The Hague
–
The Hague is a city on the western coast of the Netherlands, and the capital city of the province of South Holland. With a population of 520,704 inhabitants and more than one million including the suburbs, it is the third-largest city of the Netherlands. The Rotterdam The Hague Metropolitan Area, with a population of approximately 2.7 million, is the 12th-largest in the European Union and the most populous in the country. Located in the west of the Netherlands, The Hague is in the centre of the Haaglanden conurbation and lies at the southwest corner of the larger Randstad conurbation. The Hague is the seat of the Dutch government, parliament, the Supreme Court, and the Council of State, but the city is not the capital of the Netherlands, which constitutionally is Amsterdam. King Willem-Alexander of the Netherlands plans to live at Huis ten Bosch and works at Noordeinde Palace in The Hague, the Hague is also home to the world headquarters of Royal Dutch Shell and numerous other major Dutch companies. The Hague originated around 1230, when Count Floris IV of Holland purchased land alongside a pond, in 1248, his son and successor William II, King of the Romans, decided to extend the residence to a palace, which would later be called the Binnenhof. He died in 1256 before this palace was completed but parts of it were finished by his son Floris V, of which the Ridderzaal and it is still used for political events, such as the annual speech from the throne by the Dutch monarch. From the 13th century onwards, the counts of Holland used The Hague as their administrative centre, the village that originated around the Binnenhof was first mentioned as Haga in a charter dating from 1242. In the 15th century, the smarter des Graven hage came into use, literally The Counts Wood, with connotations like The Counts Hedge, s-Gravenhage was officially used for the city from the 17th century onwards. Today, this name is used in some official documents like birth. The city itself uses Den Haag in all its communication and their seat was located in The Hague. At the beginning of the Eighty Years War, the absence of city walls proved disastrous, in 1575, the States of Holland even considered demolishing the city but this proposal was abandoned, after mediation by William of Orange. From 1588, The Hague also became the seat of the government of the Dutch Republic, in order for the administration to maintain control over city matters, The Hague never received official city status, although it did have many of the privileges normally granted only to cities. In modern administrative law, city rights have no place anymore, only in 1806, when the Kingdom of Holland was a puppet state of the First French Empire, was the settlement granted city rights by Louis Bonaparte. After the Napoleonic Wars, modern-day Belgium and the Netherlands were combined in the United Kingdom of the Netherlands to form a buffer against France, as a compromise, Brussels and Amsterdam alternated as capital every two years, with the government remaining in The Hague. After the separation of Belgium in 1830, Amsterdam remained the capital of the Netherlands, when the government started to play a more prominent role in Dutch society after 1850, The Hague quickly expanded. The growing city annexed the rural municipality of Loosduinen partly in 1903, the city sustained heavy damage during World War II

Dutch Republic
–
It preceded the Batavian Republic, the Kingdom of Holland, the United Kingdom of the Netherlands, and ultimately the modern Kingdom of the Netherlands. Alternative names include the United Provinces, Seven Provinces, Federated Dutch Provinces, most of the Low Countries had come under the rule of the House of Burgundy and subsequently the House of Habsburg. In 1549 Holy Roman Emperor Charles V issued the Pragmatic Sanction, Charles was succeeded by his son, King Philip II of Spain. This was the start of the Eighty Years War, in 1579 a number of the northern provinces of the Low Countries signed the Union of Utrecht, in which they promised to support each other in their defence against the Spanish army. This was followed in 1581 by the Act of Abjuration, the declaration of independence of the provinces from Philip II. In 1582 the United Provinces invited Francis, Duke of Anjou to lead them, but after an attempt to take Antwerp in 1583. After the assassination of William of Orange, both Henry III of France and Elizabeth I of England declined the offer of sovereignty, however, the latter agreed to turn the United Provinces into a protectorate of England, and sent the Earl of Leicester as governor-general. This was unsuccessful and in 1588 the provinces became a confederacy, the Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Peace of Westphalia in 1648. During the Anglo-French war, the territory was divided into groups, the Patriots, who were pro-French and pro-American and the Orangists. The Republic of the United Provinces faced a series of revolutions in 1783–1787. During this period, republican forces occupied several major Dutch cities, initially on the defence, the Orangist forces received aid from Prussian troops and retook the Netherlands in 1787. After the French Republic became the French Empire under Napoleon, the Batavian Republic was replaced by the Napoleonic Kingdom of Holland, the Netherlands regained independence from France in 1813. In the Anglo-Dutch Treaty of 1814 the names United Provinces of the Netherlands, on 16 March 1815, the son of stadtholder William V crowned himself King William I of the Netherlands. Between 1815 and 1890 the King of the Netherlands was also in a union the Grand Duke of the sovereign Grand Duchy of Luxembourg. After Belgium gained its independence in 1830, the state became known as the Kingdom of the Netherlands. The County of Holland was the wealthiest and most urbanized region in the world, the free trade spirit of the time received a strong augmentation through the development of a modern, effective stock market in the Low Countries. The Netherlands has the oldest stock exchange in the world, founded in 1602 by the Dutch East India Company, while Rotterdam has the oldest bourse in the Netherlands, the worlds first stock exchange, that of the Dutch East-India Company, went public in six different cities. Later, a court ruled that the company had to reside legally in a city so Amsterdam is recognized as the oldest such institution based on modern trading principles

Poland
–
Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges in the south. Bordered by Germany to the west, the Czech Republic and Slovakia to the south, Ukraine and Belarus to the east, the total area of Poland is 312,679 square kilometres, making it the 69th largest country in the world and the 9th largest in Europe. With a population of over 38.5 million people, Poland is the 34th most populous country in the world, the 8th most populous country in Europe, Poland is a unitary state divided into 16 administrative subdivisions, and its capital and largest city is Warsaw. Other metropolises include Kraków, Wrocław, Poznań, Gdańsk and Szczecin, the establishment of a Polish state can be traced back to 966, when Mieszko I, ruler of a territory roughly coextensive with that of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, and in 1569 it cemented a political association with the Grand Duchy of Lithuania by signing the Union of Lublin. This union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, Poland regained its independence in 1918 at the end of World War I, reconstituting much of its historical territory as the Second Polish Republic. In September 1939, World War II started with the invasion of Poland by Nazi Germany, followed thereafter by invasion by the Soviet Union. More than six million Polish citizens died in the war, after the war, Polands borders were shifted westwards under the terms of the Potsdam Conference. With the backing of the Soviet Union, a communist puppet government was formed, and after a referendum in 1946. During the Revolutions of 1989 Polands Communist government was overthrown and Poland adopted a new constitution establishing itself as a democracy, informally called the Third Polish Republic. Since the early 1990s, when the transition to a primarily market-based economy began, Poland has achieved a high ranking on the Human Development Index. Poland is a country, which was categorised by the World Bank as having a high-income economy. Furthermore, it is visited by approximately 16 million tourists every year, Poland is the eighth largest economy in the European Union and was the 6th fastest growing economy on the continent between 2010 and 2015. According to the Global Peace Index for 2014, Poland is ranked 19th in the list of the safest countries in the world to live in. The origin of the name Poland derives from a West Slavic tribe of Polans that inhabited the Warta River basin of the historic Greater Poland region in the 8th century, the origin of the name Polanie itself derives from the western Slavic word pole. In some foreign languages such as Hungarian, Lithuanian, Persian and Turkish the exonym for Poland is Lechites, historians have postulated that throughout Late Antiquity, many distinct ethnic groups populated the regions of what is now Poland. The most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, the Slavic groups who would form Poland migrated to these areas in the second half of the 5th century AD. With the Baptism of Poland the Polish rulers accepted Christianity and the authority of the Roman Church

Netherlands
–
The Netherlands, also informally known as Holland is the main constituent country of the Kingdom of the Netherlands. It is a densely populated country located in Western Europe with three territories in the Caribbean. The European part of the Netherlands borders Germany to the east, Belgium to the south, and the North Sea to the northwest, sharing borders with Belgium, the United Kingdom. The three largest cities in the Netherlands are Amsterdam, Rotterdam and The Hague, Amsterdam is the countrys capital, while The Hague holds the Dutch seat of parliament and government. The port of Rotterdam is the worlds largest port outside East-Asia, the name Holland is used informally to refer to the whole of the country of the Netherlands. Netherlands literally means lower countries, influenced by its low land and flat geography, most of the areas below sea level are artificial. Since the late 16th century, large areas have been reclaimed from the sea and lakes, with a population density of 412 people per km2 –507 if water is excluded – the Netherlands is classified as a very densely populated country. Only Bangladesh, South Korea, and Taiwan have both a population and higher population density. Nevertheless, the Netherlands is the worlds second-largest exporter of food and agricultural products and this is partly due to the fertility of the soil and the mild climate. In 2001, it became the worlds first country to legalise same-sex marriage, the Netherlands is a founding member of the EU, Eurozone, G-10, NATO, OECD and WTO, as well as being a part of the Schengen Area and the trilateral Benelux Union. The first four are situated in The Hague, as is the EUs criminal intelligence agency Europol and this has led to the city being dubbed the worlds legal capital. The country also ranks second highest in the worlds 2016 Press Freedom Index, the Netherlands has a market-based mixed economy, ranking 17th of 177 countries according to the Index of Economic Freedom. It had the thirteenth-highest per capita income in the world in 2013 according to the International Monetary Fund, in 2013, the United Nations World Happiness Report ranked the Netherlands as the seventh-happiest country in the world, reflecting its high quality of life. The Netherlands also ranks joint second highest in the Inequality-adjusted Human Development Index, the region called Low Countries and the country of the Netherlands have the same toponymy. Place names with Neder, Nieder, Nether and Nedre and Bas or Inferior are in use in all over Europe. They are sometimes used in a relation to a higher ground that consecutively is indicated as Upper, Boven, Oben. In the case of the Low Countries / the Netherlands the geographical location of the region has been more or less downstream. The geographical location of the region, however, changed over time tremendously

Temperature measurement
–
Temperature measurement describes the process of measuring a current local temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends, attempts at standardized temperature measurement prior to the 17th century were crude at best. For instance in 170 AD, physician Claudius Galenus mixed equal portions of ice and these early devices were called thermoscopes. The first sealed thermometer was constructed in 1641 by the Grand Duke of Toscani, fahrenheits scale is still in use, alongside the Celsius and Kelvin scales. Many methods have developed for measuring temperature. Most of these rely on measuring some physical property of a material that varies with temperature. One of the most common devices for measuring temperature is the glass thermometer and this consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid, such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, under some conditions heat from the measuring instrument can cause a temperature gradient, so the measured temperature is different from the actual temperature of the system. In such a case the temperature will vary not only with the temperature of the system. An extreme case of this gives rise to the wind chill factor. What is happening is that the wind increases the rate of transfer from the body. B, of course, is the thermometer, the practical basis of thermometry is the existence of triple point cells. Triple points are conditions of pressure, volume and temperature such that three phases are present, for example solid, vapor and liquid. For a single component there are no degrees of freedom at a triple point, therefore, triple point cells can be used as universal references for temperature and pressure. Under some conditions it becomes possible to measure temperature by a use of the Plancks law of black-body radiation. For example, the microwave background temperature has been measured from the spectrum of photons observed by satellite observations such as the WMAP. In the study of the plasma through heavy-ion collisions, single particle spectra sometimes serve as a thermometer

Alcohol thermometer
–
The alcohol thermometer is an alternative to the mercury-in-glass thermometer and has similar functions. Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic, the ethanol version is the most widely used due to the low cost and relatively low hazard posed by the liquid in case of breakage. An organic liquid is contained in a bulb which is connected to a capillary of the same glass. The space above the liquid is a mixture of nitrogen and the vapor of the liquid, for the working temperature range, the meniscus or interface between the liquid is within the capillary. With increasing temperature, the volume of liquid expands and the meniscus moves up the capillary, the position of the meniscus shows the temperature against an inscribed scale. The liquid used can be pure ethanol, toluene, kerosene or Isoamyl acetate, depending on manufacturer, since these are transparent, the liquid is made more visible by the addition of a red or blue dye. One half of the containing the capillary is usually enamelled white or yellow to give a background for reading the scale. The range of usefulness of the thermometer is set by the point of the liquid used. Ethanol-filled thermometers are used in preference to mercury for meteorological measurements of minimum temperatures, the physical limitation of the ability of a thermometer to measure low temperature is the freezing point of the liquid used. If an alcohol thermometer utilizes a combination of alcohol, toluene. However, the measurement temperature range c. −200 °C to 78 °C, is dependent upon the type of alcohol used. The alcohol thermometer was the earliest, efficient, modern-style instrument of temperature measurement, as is the case with many early, important inventions, there are several people credited with its invention. Other sources, including the Encyclopædia Britannica, credit German scientist Daniel Gabriel Fahrenheit with inventing the alcohol thermometer in 1709, Fahrenheit was a skilled glassblower and his alcohol thermometer was the worlds first reliable thermometer

Mercury-in-glass thermometer
–
The mercury-in-glass or mercury thermometer was invented by Polish-Dutch physicist Daniel Gabriel Fahrenheit in Amsterdam. It consists of a bulb containing mercury attached to a tube of narrow diameter. The volume of mercury changes slightly with temperature, the change in volume drives the narrow mercury column a relatively long way up the tube. The space above the mercury may be filled with nitrogen or it may be at less than atmospheric pressure, the thermometer was used by the originators of the Fahrenheit and Celsius scales. Anders Celsius, a Swedish scientist, devised the Celsius scale, Celsius used two fixed points in his scale, the temperature of melting ice and the temperature of boiling water. This wasnt a new idea, since Isaac Newton was already working on something similar, the distinction of Celsius was to use the condition of melting and not that of freezing. The experiments for reaching a good calibration of his thermometer lasted for 2 winters, by performing the same experiment over and over again, he discovered that ice always melted at the same calibration mark on the thermometer. He found a fixed point in the calibration of boiling water to water vapour. At the moment that he removed the thermometer from the vapour and this was related to the rapid cooling of the glass. When Celsius decided to use his own scale, he originally defined his scale upside-down, i. e. he chose to set the boiling point of pure water at 0 °C. One year later, Frenchman Jean-Pierre Christin proposed to invert the scale with the point at 0 °C. This point is the point of water. In the same manner mark the point where the fluid stabilises when the thermometer is placed in boiling water vapour, divide the length between the two marks into 100 equal parts. These points are adequate for approximate calibration but both vary with atmospheric pressure, nowadays, the triple point of water is used instead of the freezing point. Before the discovery of the thermodynamic temperature, the thermometer defined the temperature. In practice, several materials gave very similar temperatures to each other and, a special kind of mercury-in-glass thermometer, called a maximum thermometer, works by having a constriction in the neck close to the bulb. As the temperature rises, the mercury is pushed up through the constriction by the force of expansion, when the temperature falls, the column of mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube. The observer can then read the temperature over the set period of time

Fahrenheit scale
–
Fahrenheit is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit, after whom the scale is named. It uses the degree Fahrenheit as the unit, several accounts of how he originally defined his scale exist. The lower defining point,0 °F, was established as the temperature of a solution of brine made from parts of ice. Further limits were established as the point of ice and his best estimate of the average human body temperature. All other countries in the world now use the Celsius scale, defined since 1954 by absolute zero being −273.15 °C, on the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit and the boiling point is 212 °F. This puts the boiling and freezing points of water exactly 180 degrees apart, therefore, a degree on the Fahrenheit scale is 1⁄180 of the interval between the freezing point and the boiling point. On the Celsius scale, the freezing and boiling points of water are 100 degrees apart, a temperature interval of 1 °F is equal to an interval of 5⁄9 degrees Celsius. The Fahrenheit and Celsius scales intersect at −40°, absolute zero is −273.15 °C or −459.67 °F. For an exact conversion, the formulas can be applied. Again, f is the value in Fahrenheit and c the value in Celsius, f °Fahrenheit to c °Celsius, C °Celsius to f °Fahrenheit, −40 = f. Fahrenheit proposed his temperature scale in 1724, basing it on two points of temperature. In his initial scale, the point is determined by placing the thermometer in a mixture of ice, water. This is a mixture which stabilizes its temperature automatically, that stable temperature was defined as 0 °F. The second point,96 degrees, was approximately the human bodys temperature, in any case, the definition of the Fahrenheit scale has changed since. According to a letter Fahrenheit wrote to his friend Herman Boerhaave, his scale was built on the work of Ole Rømer, whom he had met earlier. In Rømers scale, brine freezes at zero, water freezes and melts at 7.5 degrees, body temperature is 22.5, Fahrenheit multiplied each value by four in order to eliminate fractions and increase the granularity of the scale. Fahrenheit observed that water boils at about 212 degrees using this scale, under this system, the Fahrenheit scale is redefined slightly so that the freezing point of water is exactly 32 °F, and the boiling point is exactly 212 °F or 180 degrees higher. It is for this reason that human body temperature is approximately 98° on the revised scale

Fahrenheit hydrometer
–
The Fahrenheit hydrometer is a device used to measure the density of a liquid. It was invented by Daniel Gabriel Fahrenheit, better known for his work in thermometry, the Fahrenheit hydrometer is a constant-volume device that will float in water. In the figure here, the hydrometer is floating vertically in a cylinder containing a liquid. At the bottom of the hydrometer is a bulb and at the top is a pan for small weights. To use the hydrometer, one first accurately determines its weight while it is dry, next, the device is placed in water, and a weight sufficient to sink a marked point on the rod to the water-line is placed on the pan. At that point, the weight of water displaced by the instrument equals W + w, the hydrometer is then removed, wiped dry, and placed in the liquid whose density is to be determined. A weight sufficient to sink the hydrometer to the marked point is placed in the pan. The density of the liquid is then given by D = /. The Fahrenheit hydrometer can be made of glass or metal. The Nicholson hydrometer is similar in design, but instead of a bulb at the bottom there is a small container into which a sample can be placed

Physics
–
Physics is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental disciplines, the main goal of physics is to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy, Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the mechanisms of other sciences while opening new avenues of research in areas such as mathematics. Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs, the United Nations named 2005 the World Year of Physics. Astronomy is the oldest of the natural sciences, the stars and planets were often a target of worship, believed to represent their gods. While the explanations for these phenomena were often unscientific and lacking in evidence, according to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, and all Western efforts in the exact sciences are descended from late Babylonian astronomy. The most notable innovations were in the field of optics and vision, which came from the works of many scientists like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi and Avicenna. The most notable work was The Book of Optics, written by Ibn Al-Haitham, in which he was not only the first to disprove the ancient Greek idea about vision, but also came up with a new theory. In the book, he was also the first to study the phenomenon of the pinhole camera, many later European scholars and fellow polymaths, from Robert Grosseteste and Leonardo da Vinci to René Descartes, Johannes Kepler and Isaac Newton, were in his debt. Indeed, the influence of Ibn al-Haythams Optics ranks alongside that of Newtons work of the same title, the translation of The Book of Optics had a huge impact on Europe. From it, later European scholars were able to build the devices as what Ibn al-Haytham did. From this, such important things as eyeglasses, magnifying glasses, telescopes, Physics became a separate science when early modern Europeans used experimental and quantitative methods to discover what are now considered to be the laws of physics. Newton also developed calculus, the study of change, which provided new mathematical methods for solving physical problems. The discovery of new laws in thermodynamics, chemistry, and electromagnetics resulted from greater research efforts during the Industrial Revolution as energy needs increased, however, inaccuracies in classical mechanics for very small objects and very high velocities led to the development of modern physics in the 20th century. Modern physics began in the early 20th century with the work of Max Planck in quantum theory, both of these theories came about due to inaccuracies in classical mechanics in certain situations. Quantum mechanics would come to be pioneered by Werner Heisenberg, Erwin Schrödinger, from this early work, and work in related fields, the Standard Model of particle physics was derived. Areas of mathematics in general are important to this field, such as the study of probabilities, in many ways, physics stems from ancient Greek philosophy

Physicist
–
A physicist is a scientist who has specialized knowledge in the field of physics, the exploration of the interactions of matter and energy across the physical universe. A physicist is a scientist who specializes or works in the field of physics, physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists can also apply their knowledge towards solving real-world problems or developing new technologies, some physicists specialize in sectors outside the science of physics itself, such as engineering. The study and practice of physics is based on a ladder of discoveries. Many mathematical and physical ideas used today found their earliest expression in ancient Greek culture and Asian culture, the bulk of physics education can be said to flow from the scientific revolution in Europe, starting with the work of Galileo and Kepler in the early 1600s. New knowledge in the early 21st century includes an increase in understanding physical cosmology. The term physicist was coined by William Whewell in his 1840 book The Philosophy of the Inductive Sciences, many physicist positions require an undergraduate degree in applied physics or a related science or a Masters degree like MSc, MPhil, MPhys or MSci. In a research oriented level, students tend to specialize in a particular field, Physics students also need training in mathematics, and also in computer science and programming. For being employed as a physicist a doctoral background may be required for certain positions, undergraduate students like BSc Mechanical Engineering, BSc Electrical and Computer Engineering, BSc Applied Physics. etc. With physics orientation are chosen as research assistants with faculty members, the highest honor awarded to physicists is the Nobel Prize in Physics, awarded since 1901 by the Royal Swedish Academy of Sciences. The three major employers of career physicists are academic institutions, laboratories, and private industries, with the largest employer being the last, physicists in academia or government labs tend to have titles such as Assistants, Professors, Sr. /Jr. As per the American Institute for Physics, some 20% of new physics Ph. D. s holds jobs in engineering development programs, while 14% turn to computer software, a majority of physicists employed apply their skills and training to interdisciplinary sectors. For industry or self-employment. and also in science and programming. Hence a majority of Physics bachelors degree holders are employed in the private sector, other fields are academia, government and military service, nonprofit entities, labs and teaching

Inventor
–
An invention is a unique or novel device, method, composition or process. The invention process is a process within an overall engineering and product development process and it may be an improvement upon a machine or product or a new process for creating an object or a result. An invention that achieves a unique function or result may be a radical breakthrough. Such works are novel and not obvious to others skilled in the same field, an inventor may be taking a big step in success or failure. A patent legally protects the property rights of the inventor. The rules and requirements for patenting an invention vary from country to country, another meaning of invention is cultural invention, which is an innovative set of useful social behaviours adopted by people and passed on to others. The Institute for Social Inventions collected many such ideas in magazines, Invention is also an important component of artistic and design creativity. Inventions often extend the boundaries of knowledge, experience or capability. Brainstorming also can spark new ideas for an invention, collaborative creative processes are frequently used by engineers, designers, architects and scientists. Co-inventors are frequently named on patents, in addition, many inventors keep records of their working process - notebooks, photos, etc. including Leonardo da Vinci, Galileo Galilei, Evangelista Torricelli, Thomas Jefferson and Albert Einstein. In the process of developing an invention, the idea may change. The invention may become simpler, more practical, it may expand, working on one invention can lead to others too. History shows that turning the concept of an invention into a device is not always swift or direct. Inventions may also more useful after time passes and other changes occur. For example, the became more useful once powered flight was a reality. Invention is often a creative process, an open and curious mind allows an inventor to see beyond what is known. Seeing a new possibility, connection, or relationship can spark an invention, inventive thinking frequently involves combining concepts or elements from different realms that would not normally be put together. Sometimes inventors disregard the boundaries between distinctly separate territories or fields, several concepts may be considered when thinking about invention

Thermometer
–
A thermometer is a device that measures temperature or a temperature gradient. A thermometer has two important elements, a sensor in which some physical change occurs with temperature. Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, there are various principles by which different thermometers operate. They include the expansion of solids or liquids with temperature. Radiation-type thermometers measure the energy emitted by an object, allowing measurement of temperature without contact. Most metals are good conductors of heat and they are solids at room temperature, Mercury is the only one in liquid state at room temperature, and has high coefficient of expansion. Hence, the slightest change in temperature is notable when its used in a thermometer and this is the reason behind mercury and alcohol being used in thermometer. Some of the principles of the thermometer were known to Greek philosophers of two years ago. The modern thermometer gradually evolved from the thermoscope with the addition of a scale in the early 17th century, while an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is a thermodynamic temperature scale. Internationally agreed temperature scales are designed to approximate this closely, based on fixed points, the most recent official temperature scale is the International Temperature Scale of 1990. It extends from 0.65 K to approximately 1,358 K, various authors have credited the invention of the thermometer to Hero of Alexandria. The thermometer was not an invention, however, but a development. The expansion and contraction of the air caused the position of the interface to move along the tube. Such a mechanism was used to show the hotness and coldness of the air with a tube in which the water level is controlled by the expansion and contraction of the gas. These devices were developed by several European scientists in the 16th and 17th centuries, as a result, devices were shown to produce this effect reliably, and the term thermoscope was adopted because it reflected the changes in sensible heat. The difference between a thermoscope and a thermometer is that the latter has a scale, though Galileo is often said to be the inventor of the thermometer, what he produced were thermoscopes. The first clear diagram of a thermoscope was published in 1617 by Giuseppe Biancani and this was a vertical tube, closed by a bulb of air at the top, with the lower end opening into a vessel of water

Hanseatic League
–
The Hanseatic League was a commercial and defensive confederation of merchant guilds and their market towns. Growing from a few North German towns in the late 1100s and it stretched from the Baltic to the North Sea and inland during the Late Middle Ages and early modern period. Hanse, later spelled as Hansa, was the Middle Low German word for a convoy, the League was created to protect the guilds economic interests and diplomatic privileges in their affiliated cities and countries, as well as along the trade routes the merchants visited. The Hanseatic cities had their own system and furnished their own armies for mutual protection. The hegemony of Lübeck peaked during the 15th century, Lübeck became a base for merchants from Saxony and Westphalia trading eastward and northward. This area was a source of timber, wax, amber, resins, the towns raised their own armies, with each guild required to provide levies when needed. The Hanseatic cities came to the aid of one another, and commercial ships often had to be used to carry soldiers, Visby functioned as the leading centre in the Baltic before the Hansa. Sailing east, Visby merchants established a trading post at Novgorod called Gutagard in 1080, Merchants from northern Germany also stayed in the early period of the Gotlander settlement. Later they established their own trading station in Novgorod, known as Peterhof, in 1229, German merchants at Novgorod were granted certain privileges that made their position more secure. Hansa societies worked to remove restrictions to trade for their members, before the official foundation of the League in 1356, the word Hanse did not occur in the Baltic language. The earliest remaining documentary mention, although without a name, of a specific German commercial federation is from London 1157. That year, the merchants of the Hansa in Cologne convinced Henry II, King of England, to them from all tolls in London. The allied cities gained control over most of the trade, especially the Scania Market. In 1266, Henry III of England granted the Lübeck and Hamburg Hansa a charter for operations in England, much of the drive for this co-operation came from the fragmented nature of existing territorial government, which failed to provide security for trade. Over the next 50 years the Hansa itself emerged with formal agreements for confederation and co-operation covering the west and east trade routes. The principal city and linchpin remained Lübeck, with the first general Diet of the Hansa held there in 1356, other such alliances formed throughout the Holy Roman Empire. Yet the League never became a closely managed formal organisation, over the period, a network of alliances grew to include a flexible roster of 70 to 170 cities. The league succeeded in establishing additional Kontors in Bruges, Bergen and these trading posts became significant enclaves

The Dutch Golden Age was a period in Dutch history, roughly spanning the 17th century, in which Dutch trade, science, military, and art were among the most acclaimed in the world. The first half is characterized by the Eighty Years War which ended in 1648, the Golden Age continued in peacetime during the Dutch Republic until the end of the century. The Netherlandss transition from a possession of the Holy Roman Empire in the 1590s to the foremost maritime, in 1568, the Seven Provinces that later signed the Union of Utrecht started a rebellion against Philip II of Spain that led to the Eighty Years War. Antwerp fell on August 17,1585 after a siege, the United Provinces fought on until the Twelve Years Truce, which did not end the hostilities. Under the terms of the surrender of Antwerp in 1585, the Protestant population were given four years to settle their affairs before leaving the city, similar arrangements were made in other places. Protestants were especially well-represented among the craftsmen and rich merchants of the port cities of Bruges, Ghent. More moved to the north between 1585 and 1630 than Catholics moved in the direction, although there were also many of these. Many of those moving north settled in Amsterdam, transforming what was a port into one of the most important ports. The Pilgrim Fathers also spent time there before their voyage to the New World, Ronald Findlay and Kevin H. O’Rourke contribute part of the Dutch ascendancy to its Calvinistic ethic, which promoted thrift and education. This contributed to the lowest interest rates and the highest literacy rates in Europe, several other factors also contributed to the flowering of trade, industry, the arts and the sciences in the Netherlands during this time. A necessary condition was a supply of energy from windmills and from peat. The invention of the sawmill enabled the construction of a massive fleet of ships for worldwide trading. In 1602 the Dutch East India Company was founded and it was the first-ever multinational corporation, financed by shares that established the first modern stock exchange. This company received a Dutch monopoly on Asian trade and would keep this for two centuries and it became the worlds largest commercial enterprise of the 17th century. Spices were imported in bulk and brought huge profits, due to the efforts and risks involved and this is remembered to this day in the Dutch word peperduur, meaning something is very expensive, reflecting the prices of spices at the time. To finance the trade within the region, the Bank of Amsterdam was established in 1609. According to Ronald Findlay and Kevin H. O’Rourke, geography favored the Dutch Republic and they write, The foundations were laid by taking advantage of location, midway between the Bay of Biscay and the Baltic. The Dutch share of European shipping tonnage was enormous, well over half during most of the period of their ascendancy, from here the Dutch traded between China and Japan and paid tribute to the Shogun

The city territory of Rostock stretches for about 20 km along the Warnow to the Baltic Sea, the largest built-up area of Rostock is on the western side of the river. The eastern part of its territory is dominated by industrial estates, Rostock is considered as the only regiopolis in Mecklenburg-Vorpommern. In the 11th century Polabian Slavs founded a settlement at the Warnow river called Roztoc, the Danish king Valdemar I set the town aflame in 1161. Afterwards the place was settled by German traders, initially there were three separate cities, Altstadt around the Alter Markt with St. Petri, Mittelstadt around the Neuer Markt with St. Marien and Neustadt around the Hopfenmarkt with St. Jakobi. In 1218, Rostock was granted Lübeck law city rights by Heinrich Borwin, during the first partition of Mecklenburg following the death of Henry Borwin II of Mecklenburg in 1226, Rostock became the seat of the Lordship of Rostock, which survived for almost a century.

A town seal from 1383 and a 15th-century signet name the town as nova civitas, or new town, but this designation was not used in documents. Founded within the state of the Teutonic Order, Kneiphof was the youngest of Königsbergs three towns, each of which had its own charter, market rights, church, settlement by merchants was intensified in 1324 with construction along the Langgasse and the bridges Krämerbrücke and Grüne Brücke. It was granted Kulm rights on 6 April 1327 by Grand Master Werner von Orseln, Kneiphofs coat of arms depicted a blue-clad arm extending from waves and holding a crown, flanked by two golden hunting horns in a green field.

Amsterdams name derives from Amstelredamme, indicative of the citys origin around a dam in the river Amstel, during that time, the city was the leading centre for finance and diamonds. In the 19th and 20th centuries the city expanded, and many new neighborhoods and suburbs were planned, the 17th-century canals of Amsterdam and the 19–20th century Defence Line of Amsterdam are on the UNESCO World Heritage List. As the commercial capital of the Netherlands and one of the top financial centres in Europe, Amsterdam is considered a world city by the Globalization. The city is also the capital of the Netherlands. Many large Dutch institutions have their headquarters there, and seven of the worlds 500 largest companies, including Philips and ING, are based in the city.

By 1327, the name had developed into Aemsterdam, Amsterdam is much younger than Dutch cities such as Nijmegen, Rotterdam, and Utrecht. In October 2008, historical geographer Chris de Bont suggested that the land around Amsterdam was being reclaimed as early as the late 10th century. This does not necessarily mean there was already a settlement then, since reclamation of land may not have been for farming—it may have been for peat. Amsterdam was granted city rights in either 1300 or 1306, from the 14th century on, Amsterdam flourished, largely from trade with the Hanseatic League

Amanita phalloides
–
Amanita phalloides /æməˈnaɪtə fəˈlɔɪdiːz/, commonly known as the death cap, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Widely distributed across Europe, A. phalloides forms ectomycorrhizas with various broadleaved trees, in some cases, the death cap has been introduced to new regions with the cultivation of non-native species of oak, chestnut, and pine. The large fruiting bodies appear in summer and autumn, the caps are generally greenish in colour, with a white stipe and these toxic mushrooms resemble several edible species commonly consumed by humans, increasing the risk of accidental poisoning. Amatoxins, the class of toxins found in mushrooms, are thermostable, they resist changes due to heat and so. A. phalloides is one of the most poisonous of all known toadstools and it is estimated that as little as half a mushroom contains enough toxin to kill an adult human. It has been involved in the majority of deaths from mushroom poisoning, possibly including the deaths of Roman Emperor Claudius in AD54. It has been the subject of research, and many of its biologically active agents have been isolated. The principal toxic constituent is α-amanitin, which damages the liver and kidneys, causing hepatic, the death cap is named in Latin as such in the correspondence between the English physician Thomas Browne and Christopher Merrett. Though the scientific name phalloides means phallus-shaped, it is whether it is named for its resemblance to a literal phallus or the stinkhorn mushrooms Phallus. In 1821, Elias Magnus Fries described it as Agaricus phalloides, finally in 1833, Johann Heinrich Friedrich Link settled on the name Amanita phalloides, after Persoon had named it Amanita viridis 30 years earlier. Amanita phalloides is the species of Amanita section Phalloideae, a group that contains all of the deadly poisonous Amanita species thus far identified. Most notable of these are the known as destroying angels, namely Amanita virosa and Amanita bisporigera. The term destroying angel has been applied to A. phalloides at times, other common names also listed include stinking amanita and deadly amanita. A rarely appearing, all-white form was initially described A. phalloides f. alba by Max Britzelmayr and it is often found growing amid normally colored death caps. It has been described, in 2004, as a distinct variety, the true Amanita verna fruits in spring and turns yellow with KOH solution, whereas A. phalloides never does. The death cap has a large and imposing epigeous fruiting body, usually with a pileus from 5 to 15 cm across, initially rounded and hemispherical, but flattening with age. The color of the cap can be pale-, yellowish-, or olive-green, often paler toward the margins, the cap surface is sticky when wet and easily peeled, a troublesome feature, as that is allegedly a feature of edible fungi. The remains of the veil are seen as a skirtlike

Christian Wolff was a German philosopher. The mountain Mons Wolff on the Moon is named in his honor, Wolff was the most eminent German philosopher between Leibniz and Kant. Wolff was also the creator of German as the language of instruction and research, although he also wrote in Latin, so that an international audience could. Wolff was born in Breslau, Silesia, into a modest family and he studied mathematics and physics at the University of Jena, soon adding philosophy. In 1703, he qualified as Privatdozent at Leipzig University, where he lectured until 1706, by this time he had made the acquaintance of Leibniz, of whose philosophy his own system is a modified version. At Halle, Wolff at first restricted himself to mathematics, but on the departure of a colleague, he added physics, however, the claims Wolff advanced on behalf of philosophical reason appeared impious to his theological colleagues. Halle was the headquarters of Pietism, which, after a struggle against Lutheran dogmatism, had assumed the characteristics of a new orthodoxy. Wolffs professed ideal was to base theological truths on mathematically certain evidence, on 12 July 1723 Wolff held a lecture for students and the magistrates at the end of his term as a rector. Wolff compared, based on books by the Belgian missionaries François Noël and Philippe Couplet, Moses, Christ, according to Voltaire professor August Hermann Francke had been teaching in an empty classroom but Wolff attracted with his lectures around 1,000 students from all over. In the following up Wolff was accused by Francke of fatalism and atheism, as a consequence, Wolff was ousted in 1723 from his first chair at Halle in one of the most celebrated academic dramas of the 18th century. His successors were Joachim Lange, a pietist, and his son and this so enraged the king that he immediately deprived Wolff of his office, and commanded him to leave Prussian territory within 48 hours or be hanged. The same day Wolff passed into Saxony, and presently proceeded to Marburg, Hesse-Kassel, to university he had received a call even before this crisis. The Landgrave of Hesse received him with every mark of distinction, and it was everywhere discussed, and over two hundred books and pamphlets appeared for or against it before 1737, not reckoning the systematic treatises of Wolff and his followers. In 1726 Wolff published his Discours, in which he mentioned the importance of listening to music put on pregnant Chinese women. At the University of Marburg, as one of the most popular and fashionable university teachers in Europe, Frederick proposed to send a copy of Logique ou réflexions sur les forces de lentendement humain to Voltaire in his first letter to the philosopher from 8 August 1736. In 1737 Wolffs Metafysica was translated into French by Ulrich Friedrich von Suhm, Voltaire got the impression Frederick had translated the book himself. In 1738 Frederick William begun the hard labour of trying to read Wolff, in 1740 Frederick William died, and one of the first acts of his son and successor, Frederick the Great, was to acquire him for the Prussian Academy. Wolff refused, but accepted on 10 September 1740 an appointment in Halle and his entry into the town on 6 December 1740 took on the character of a triumphal procession

Gottfried Wilhelm Leibniz
–
Leibnizs notation has been widely used ever since it was published. It was only in the 20th century that his Law of Continuity and he became one of the most prolific inventors in the field of mechanical calculators. He also refined the number system, which is the foundation of virtually all digital computers. Leibniz, along with René Descartes and Baruch Spinoza, was one of the three great 17th-century advocates of rationalism and he wrote works on philosophy, politics, law, ethics, theology, history, and philology. Leibnizs contributions to this vast array of subjects were scattered in various learned journals, in tens of thousands of letters and he wrote in several languages, but primarily in Latin, French, and German. There is no complete gathering of the writings of Leibniz in English, Gottfried Leibniz was born on July 1,1646, toward the end of the Thirty Years War, in Leipzig, Saxony, to Friedrich Leibniz and Catharina Schmuck. Friedrich noted in his journal,21. Juny am Sontag 1646 Ist mein Sohn Gottfried Wilhelm, post sextam vespertinam 1/4 uff 7 uhr abents zur welt gebohren, in English, On Sunday 21 June 1646, my son Gottfried Wilhelm is born into the world a quarter after six in the evening, in Aquarius. Leibniz was baptized on July 3 of that year at St. Nicholas Church, Leipzig and his father died when he was six and a half years old, and from that point on he was raised by his mother. Her teachings influenced Leibnizs philosophical thoughts in his later life, Leibnizs father had been a Professor of Moral Philosophy at the University of Leipzig, and the boy later inherited his fathers personal library. He was given access to it from the age of seven. Access to his fathers library, largely written in Latin, also led to his proficiency in the Latin language and he also composed 300 hexameters of Latin verse, in a single morning, for a special event at school at the age of 13. In April 1661 he enrolled in his fathers former university at age 15 and he defended his Disputatio Metaphysica de Principio Individui, which addressed the principle of individuation, on June 9,1663. Leibniz earned his masters degree in Philosophy on February 7,1664, after one year of legal studies, he was awarded his bachelors degree in Law on September 28,1665. His dissertation was titled De conditionibus, in early 1666, at age 19, Leibniz wrote his first book, De Arte Combinatoria, the first part of which was also his habilitation thesis in Philosophy, which he defended in March 1666. His next goal was to earn his license and Doctorate in Law, in 1666, the University of Leipzig turned down Leibnizs doctoral application and refused to grant him a Doctorate in Law, most likely due to his relative youth. Leibniz then enrolled in the University of Altdorf and quickly submitted a thesis, the title of his thesis was Disputatio Inauguralis de Casibus Perplexis in Jure. Leibniz earned his license to practice law and his Doctorate in Law in November 1666 and he next declined the offer of an academic appointment at Altdorf, saying that my thoughts were turned in an entirely different direction

Glassblowing
–
Glassblowing is a glassforming technique that involves inflating molten glass into a bubble, with the aid of a blowpipe. A person who blows glass is called a glassblower, glassmith, a lampworker manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass. To increase the stiffness of the glass, which in turn facilitates the process of blowing. Lower concentration of natron would have allowed the glass to be stiffer for blowing, during blowing, thinner layers of glass cool faster than thicker ones and become more viscous than the thicker layers. That allows production of glass with uniform thickness instead of causing blow-through of the thinned layers. A full range of glassblowing techniques was developed within decades of its invention, the two major methods of glassblowing are free-blowing and mold-blowing. The process of free-blowing involves the blowing of short puffs of air into a portion of glass called a gather which has been spooled at one end of the blowpipe. This has the effect of forming an elastic skin on the interior of the glass blob that matches the skin caused by the removal of heat from the furnace. The glassworker can then quickly inflate the molten glass to a coherent blob, researchers at the Toledo Museum of Art attempted to reconstruct the ancient free-blowing technique by using clay blowpipes. The result proved that short clay blowpipes of about 30–60 cm facilitate free-blowing because they are simple to handle and to manipulate, skilled workers are capable of shaping almost any vessel forms by rotating the pipe, swinging it and controlling the temperature of the piece while they blow. They can produce a variety of glass objects, ranging from drinking cups to window glass. An outstanding example of the technique is the Portland Vase. An experiment was carried out by Gudenrath and Whitehouse with the aim of re-creating the Portland Vase, a full amount of blue glass required for the body of the vase was gathered on the end of the blowpipe and was subsequently dipped into a pot of hot white glass. Inflation occurred when the glassworker blew the molten glass into a sphere which was then stretched or elongated into a vase with a layer of white glass overlying the blue body. Mold-blowing was an alternative glassblowing method that came after the invention of free-blowing, during the first part of the quarter of the 1st century AD. A glob of molten glass is placed on the end of the blowpipe, in that way, the shape and the texture of the bubble of glass is determined by the design on the interior of the mold rather than the skill of the glassworker. Two types of molds, namely single-piece mold and multi-piece mold, are used to produce mold-blown vessels. Whereas the latter is made in multi-paneled mold segments that together, thus permitting the development of more sophisticated surface modeling, texture

Barometer
–
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather, numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems and frontal boundaries. Barometers and pressure altimeters are essentially the same instrument, but used for different purposes, the main exception to this is ships at sea, which can use a barometer because their elevation does not change. Due to the presence of weather systems, aircraft altimeters may need to be adjusted as they fly between regions of varying normalized atmospheric pressure. On July 27,1630, Giovanni Battista Baliani wrote a letter to Galileo Galilei explaining an experiment he had made in which a siphon, led over a hill about twenty-one meters high, failed to work. This was a restatement of the theory of horror vacui, which dates to Aristotle, galileos ideas reached Rome in December 1638 in his Discorsi. Raffaele Magiotti and Gasparo Berti were excited by these ideas, Magiotti devised such an experiment, and sometime between 1639 and 1641, Berti carried it out. The bottom end of the tube was opened, and water that had been inside of it poured out into the basin. What was most important about this experiment was that the water had left a space above it in the tube which had no intermediate contact with air to fill it up. This seemed to suggest the possibility of a vacuum existing in the space above the water, Torricelli, a friend and student of Galileo, interpreted the results of the experiments in a novel way. He proposed that the weight of the atmosphere, not a force of the vacuum. It was traditionally thought that the air did not have weight, that is. Even Galileo had accepted the weightlessness of air as a simple truth, Torricelli questioned that assumption, and instead proposed that air had weight and that it was the latter which held up the column of water. He thought that the level the water stayed at was reflective of the force of the airs weight pushing on it. In other words, he viewed the barometer as a balance, an instrument for measurement and he needed to use a liquid that was heavier than water, and from his previous association and suggestions by Galileo, he deduced by using mercury, a shorter tube could be used. With mercury, which is about 14 times heavier than water, Pascal further devised an experiment to test the Aristotelian proposition that it was vapors from the liquid that filled the space in a barometer. His experiment compared water with wine, and since the latter was considered more spiritous, Pascal performed the experiment publicly, inviting the Aristotelians to predict the outcome beforehand. The Aristotelians predicted the wine would stand lower, however, Pascal went even further to test the mechanical theory

Altimeter
–
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, altitude can be determined based on the measurement of atmospheric pressure. The greater the altitude, the lower the pressure, when a barometer is supplied with a nonlinear calibration so as to indicate altitude, the instrument is called a pressure altimeter or barometric altimeter. A pressure altimeter is the altimeter found in most aircraft, hikers and mountain climbers use wrist-mounted or hand-held altimeters, in addition to other navigational tools such as a map, magnetic compass, or GPS receiver. The calibration of an altimeter follows the equation z = c T log , where c is a constant, T is the temperature, P is the pressure at altitude z. The constant c depends on the acceleration of gravity and the mass of the air. A barometric altimeter, used along with a map, can help to verify ones location. An altimeter is the most important piece of skydiving equipment, after the parachute itself, altitude awareness is crucial at all times during the jump, and determines the appropriate response to maintain safety. This is the most basic and common type, and is used by all student skydivers. The common design has a face marked from 0 to 4000m, the face plate sports sections prominently marked with yellow and red respectively, signifying the recommended deployment altitude, as well as emergency procedure decision altitude. Some advanced electronic altimeters are also available which use of the familiar analogue display. Digital visual altimeters, mounted on the wrist or hand and this type always operates electronically, and conveys the altitude as a number, rather than a pointer on a dial. An electronic altimeter is turned on on the ground before jump, if the intended landing zone is at a different elevation than the takeoff point, the user needs to input the appropriate offset by using a designated function. These are inserted into ones helmet, and emit a warning tone at a predefined altitude, audibles are strictly auxiliary devices, and do not replace, but complement a visual altimeter which remains the primary tool for maintaining altitude awareness. Audibles are not recommended and often banned from use by student skydivers and these do not show the precise altitude, but rather help maintain a general indicator in ones peripheral vision. The exact choice of altimeters depends heavily on the individual preferences, experience level, primary disciplines. On one end of the spectrum, a demonstration jump with water landing and no free fall might waive the mandated use of altimeters. Another skydiver doing similar types of jumps might wear a digital altimeter for their primary visual one, in aircraft, an aneroid barometer measures the atmospheric pressure from a static port outside the aircraft

Chemistry
–
Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry is sometimes called the science because it bridges other natural sciences, including physics. For the differences between chemistry and physics see comparison of chemistry and physics, the history of chemistry can be traced to alchemy, which had been practiced for several millennia in various parts of the world. The word chemistry comes from alchemy, which referred to a set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism. An alchemist was called a chemist in popular speech, and later the suffix -ry was added to this to describe the art of the chemist as chemistry, the modern word alchemy in turn is derived from the Arabic word al-kīmīā. In origin, the term is borrowed from the Greek χημία or χημεία and this may have Egyptian origins since al-kīmīā is derived from the Greek χημία, which is in turn derived from the word Chemi or Kimi, which is the ancient name of Egypt in Egyptian. Alternately, al-kīmīā may derive from χημεία, meaning cast together, in retrospect, the definition of chemistry has changed over time, as new discoveries and theories add to the functionality of the science. The term chymistry, in the view of noted scientist Robert Boyle in 1661, in 1837, Jean-Baptiste Dumas considered the word chemistry to refer to the science concerned with the laws and effects of molecular forces. More recently, in 1998, Professor Raymond Chang broadened the definition of chemistry to mean the study of matter, early civilizations, such as the Egyptians Babylonians, Indians amassed practical knowledge concerning the arts of metallurgy, pottery and dyes, but didnt develop a systematic theory. Greek atomism dates back to 440 BC, arising in works by such as Democritus and Epicurus. In 50 BC, the Roman philosopher Lucretius expanded upon the theory in his book De rerum natura, unlike modern concepts of science, Greek atomism was purely philosophical in nature, with little concern for empirical observations and no concern for chemical experiments. Work, particularly the development of distillation, continued in the early Byzantine period with the most famous practitioner being the 4th century Greek-Egyptian Zosimos of Panopolis. He formulated Boyles law, rejected the four elements and proposed a mechanistic alternative of atoms. Before his work, though, many important discoveries had been made, the Scottish chemist Joseph Black and the Dutchman J. B. English scientist John Dalton proposed the theory of atoms, that all substances are composed of indivisible atoms of matter. Davy discovered nine new elements including the alkali metals by extracting them from their oxides with electric current, british William Prout first proposed ordering all the elements by their atomic weight as all atoms had a weight that was an exact multiple of the atomic weight of hydrogen. The inert gases, later called the noble gases were discovered by William Ramsay in collaboration with Lord Rayleigh at the end of the century, thereby filling in the basic structure of the table. Organic chemistry was developed by Justus von Liebig and others, following Friedrich Wöhlers synthesis of urea which proved that organisms were, in theory

Kloosterkerk, The Hague
–
The Kloosterkerk is a church on the Lange Voorhout in The Hague, Netherlands. The church and its monastery were first built in 1397. The church is today as the church where Beatrix of the Netherlands occasionally attends services. Origins of the monastery and church that occupied this site may be found in the Dominican Order. Reforms undertaken by Raymond of Capua, brought a growth to the order. A thriving new center of arts was established in The Hague by the Court of Albrecht of Bavaria, from December 1399 Dirc van Delf was among the court of the Duke Albrecht of Bavaria in The Hague. There he had the function of court chaplain, but he lectured at German universities, such as Cologne. In 1420 a fire raged through the monastery, but serious renovations are not recorded until the southern transept was added in the beginning of the 16th century. The church was expanded around 1540 with an aisle and side chapels. The center barrel vaulted aisle is 20 meters high and 11.5 meters wide, the worship space became a pilgrimage church, where people could visit and pass through, while services were being held in the central aisle or nave. At this time the church was dedicated to St. Vincent. It was stripped of Catholic decorations during the beeldenstorm, a number of monks lived on for a few more years, but in 1574 the last few monks left. After being abandoned for 12 years, the church had deteriorated, in 1588 a cavalry company seeking shelter settled in the former church. The following year the church and choir were made into a foundry for the States of Holland. The choir was used as a foundry and the served as a munition store with the two walled off from each other. On November 3,1690, the ammunition stored in the church exploded leaving only one wall of the monastery remaining, the monastery then temporarily served as a hospital. In 1583 most of the monastery was demolished, though the church remained, a part of the building became a church again in 1617 after Remonstrants had successfully squatted it. In 1617 it was split when a conflict over Arminianism erupted, a great debate ensued between political and religious authorities

Fahrenheit
–
Fahrenheit is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit, after whom the scale is named. It uses the degree Fahrenheit as the unit, several accounts of how he originally defined his scale exist. The lower defining point,0 °F, was established as the temperature of a solution of brine made from parts of ice. Further limits were established as the point of ice and his best estimate of the average human body temperature. All other countries in the world now use the Celsius scale, defined since 1954 by absolute zero being −273.15 °C, on the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit and the boiling point is 212 °F. This puts the boiling and freezing points of water exactly 180 degrees apart, therefore, a degree on the Fahrenheit scale is 1⁄180 of the interval between the freezing point and the boiling point. On the Celsius scale, the freezing and boiling points of water are 100 degrees apart, a temperature interval of 1 °F is equal to an interval of 5⁄9 degrees Celsius. The Fahrenheit and Celsius scales intersect at −40°, absolute zero is −273.15 °C or −459.67 °F. For an exact conversion, the formulas can be applied. Again, f is the value in Fahrenheit and c the value in Celsius, f °Fahrenheit to c °Celsius, C °Celsius to f °Fahrenheit, −40 = f. Fahrenheit proposed his temperature scale in 1724, basing it on two points of temperature. In his initial scale, the point is determined by placing the thermometer in a mixture of ice, water. This is a mixture which stabilizes its temperature automatically, that stable temperature was defined as 0 °F. The second point,96 degrees, was approximately the human bodys temperature, in any case, the definition of the Fahrenheit scale has changed since. According to a letter Fahrenheit wrote to his friend Herman Boerhaave, his scale was built on the work of Ole Rømer, whom he had met earlier. In Rømers scale, brine freezes at zero, water freezes and melts at 7.5 degrees, body temperature is 22.5, Fahrenheit multiplied each value by four in order to eliminate fractions and increase the granularity of the scale. Fahrenheit observed that water boils at about 212 degrees using this scale, under this system, the Fahrenheit scale is redefined slightly so that the freezing point of water is exactly 32 °F, and the boiling point is exactly 212 °F or 180 degrees higher. It is for this reason that human body temperature is approximately 98° on the revised scale

Celsius
–
Celsius, also known as centigrade, is a metric scale and unit of measurement for temperature. As an SI derived unit, it is used by most countries in the world and it is named after the Swedish astronomer Anders Celsius, who developed a similar temperature scale. The degree Celsius can refer to a temperature on the Celsius scale as well as a unit to indicate a temperature interval. Before being renamed to honour Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps. The scale is based on 0° for the point of water. This scale is widely taught in schools today, by international agreement the unit degree Celsius and the Celsius scale are currently defined by two different temperatures, absolute zero, and the triple point of VSMOW. This definition also precisely relates the Celsius scale to the Kelvin scale, absolute zero, the lowest temperature possible, is defined as being precisely 0 K and −273.15 °C. The temperature of the point of water is defined as precisely 273.16 K at 611.657 pascals pressure. This definition fixes the magnitude of both the degree Celsius and the kelvin as precisely 1 part in 273.16 of the difference between absolute zero and the point of water. Thus, it sets the magnitude of one degree Celsius and that of one kelvin as exactly the same, additionally, it establishes the difference between the two scales null points as being precisely 273.15 degrees. In his paper Observations of two persistent degrees on a thermometer, he recounted his experiments showing that the point of ice is essentially unaffected by pressure. He also determined with precision how the boiling point of water varied as a function of atmospheric pressure. He proposed that the point of his temperature scale, being the boiling point. This pressure is known as one standard atmosphere, the BIPMs 10th General Conference on Weights and Measures later defined one standard atmosphere to equal precisely 1013250dynes per square centimetre. On 19 May 1743 he published the design of a mercury thermometer, in 1744, coincident with the death of Anders Celsius, the Swedish botanist Carolus Linnaeus reversed Celsiuss scale. In it, Linnaeus recounted the temperatures inside the orangery at the University of Uppsala Botanical Garden, since the 19th century, the scientific and thermometry communities worldwide referred to this scale as the centigrade scale. Temperatures on the scale were often reported simply as degrees or. More properly, what was defined as centigrade then would now be hectograde.2 gradians, for scientific use, Celsius is the term usually used, with centigrade otherwise continuing to be in common but decreasing use, especially in informal contexts in English-speaking countries

Mercury (element)
–
Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum, Mercury occurs in deposits throughout the world mostly as cinnabar. The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide, likewise, mechanical pressure gauges and electronic strain gauge sensors have replaced mercury sphygmomanometers. Mercury remains in use in research applications and in amalgam for dental restoration in some locales. It is used in fluorescent lighting, electricity passed through mercury vapor in a fluorescent lamp produces short-wave ultraviolet light which then causes the phosphor in the tube to fluoresce, making visible light. Mercury poisoning can result from exposure to water-soluble forms of mercury, Mercury is a heavy, silvery-white liquid metal. Compared to other metals, it is a conductor of heat. It has a point of −38.83 °C and a boiling point of 356.73 °C. Upon freezing, the volume of mercury decreases by 3. 59%, the coefficient of volume expansion is 181.59 × 10−6 at 0 °C,181.71 × 10−6 at 20 °C and 182.50 × 10−6 at 100 °C. Solid mercury is malleable and ductile and can be cut with a knife, because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gases, which form weak bonds and hence melt at low temperatures. The stability of the 6s shell is due to the presence of a filled 4f shell, an f shell poorly screens the nuclear charge that increases the attractive Coulomb interaction of the 6s shell and the nucleus. Like silver, mercury reacts with hydrogen sulfide. Mercury reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury, Mercury dissolves many other metals such as gold and silver to form amalgams. Iron is an exception, and iron flasks have traditionally used to trade mercury. Several other first row transition metals with the exception of manganese, copper, other elements that do not readily form amalgams with mercury include platinum. Sodium amalgam is a reducing agent in organic synthesis, and is also used in high-pressure sodium lamps. Mercury readily combines with aluminium to form a mercury-aluminium amalgam when the two pure metals come into contact, since the amalgam destroys the aluminium oxide layer which protects metallic aluminium from oxidizing in-depth, even small amounts of mercury can seriously corrode aluminium. For this reason, mercury is not allowed aboard an aircraft under most circumstances because of the risk of it forming an amalgam with exposed aluminium parts in the aircraft, Mercury embrittlement is the most common type of liquid metal embrittlement

Ice
–
Ice is water frozen into a solid state. Depending on the presence of such as particles of soil or bubbles of air. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far as away the Oort cloud objects, beyond the Solar System, it occurs as interstellar ice. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes, Ice molecules can exhibit up to sixteen different phases that depend on temperature and pressure. When water is cooled rapidly, up to three different types of ice can form depending on the history of its pressure and temperature. When cooled slowly correlated proton tunneling occurs below 20 K giving rise to macroscopic quantum phenomena, virtually all the ice on Earths surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih with minute traces of cubic ice denoted as ice Ic. The most common phase transition to ice Ih occurs when water is cooled below 0°C at standard atmospheric pressure. It may also be deposited directly by water vapor, as happens in the formation of frost, the transition from ice to water is melting and from ice directly to water vapor is sublimation. Ice is used in a variety of ways, including cooling, winter sports, as a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered a mineral. It possesses a regular crystalline structure based on the molecule of water, an unusual property of ice frozen at atmospheric pressure is that the solid is approximately 8. 3% less dense than liquid water. The density of ice is 0.9167 g/cm3 at 0 °C, liquid water is densest, essentially 1.00 g/cm³, at 4 °C and becomes less dense as the water molecules begin to form the hexagonal crystals of ice as the freezing point is reached. This is due to hydrogen bonding dominating the intermolecular forces, which results in a packing of molecules less compact in the solid, density of ice increases slightly with decreasing temperature and has a value of 0.9340 g/cm³ at −180 °C. When water freezes, it increases in volume and it is also a common cause of the flooding of houses when water pipes burst due to the pressure of expanding water when it freezes. The result of this process is that ice floats on liquid water, sufficiently thin ice sheets allow light to pass through while protecting the underside from short-term weather extremes such as wind chill. This creates an environment for bacterial and algal colonies. When ice melts, it absorbs as much energy as it would take to heat an equivalent mass of water by 80 °C, during the melting process, the temperature remains constant at 0 °C. While melting, any energy added breaks the bonds between ice molecules. Energy becomes available to increase the thermal energy only after enough hydrogen bonds are broken that the ice can be considered liquid water, the amount of energy consumed in breaking hydrogen bonds in the transition from ice to water is known as the heat of fusion

Ammonium chloride
–
Ammonium chloride is an inorganic compound with the formula NH4Cl and a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic, sal ammoniac is a name of the natural, mineralogical form of ammonium chloride. The mineral is formed on burning coal dumps from condensation of coal-derived gases. It is also found some types of volcanic vents. It is mainly used as fertilizer and an agent in some types of liquorice. It is the product from the reaction of acid and ammonia. The crystals deposit directly from the state and tend to be short-lived. Ammonium chloride appears to sublime upon heating but actually decomposes into ammonia, some of ammonium chlorides reactions with other chemicals are endothermic like its reaction with barium hydroxide and its dissolving in water. The main application of ammonium chloride is as a source in fertilizers such as chloroammonium phosphate. The main crops are rice and wheat in Asia, Ammonium chloride was used in pyrotechnics in the 18th century but was superseded by safer and less hygroscopic chemicals. Its purpose was to provide a donor to enhance the green. It had a use to provide white smoke, but its ready double decomposition reaction with potassium chlorate producing the highly unstable ammonium chlorate made its use very suspect. Ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized or soldered and it works as a flux by cleaning the surface of workpieces by reacting with the metal oxides at the surface to form a volatile metal chloride. For that purpose, it is sold in blocks at hardware stores for use in cleaning the tip of a soldering iron, Ammonium chloride is used as an expectorant in cough medicine. Its expectorant action is caused by action on the bronchial mucosa, which causes the production of excess respiratory tract fluid. Ammonium salts are an irritant to the mucosa and may induce nausea. In several countries, ammonium chloride, under the name sal ammoniac or colloquially salmiakki is used as food additive under the E number E510 and it is a feed supplement for cattle and an ingredient in nutritive media for yeasts and many microorganisms. Ammonium chloride is used to spice up dark sweets called salty liquorice, in baking to give cookies a very crisp texture, in India and Pakistan, it is called Noshader and is used to improve the crispness of snacks such as samosas and jalebi

Highly composite number
–
A highly composite number is a positive integer with more divisors than any smaller positive integer has. The term was coined by Ramanujan, the related concept of largely composite number refers to a positive integer which has at least as many divisors as any smaller positive integer. The initial or smallest 38 highly composite numbers are listed in the table below, the number of divisors is given in the column labeled d. The table below shows all the divisors of one of these numbers, the 15, 000th highly composite number can be found on Achim Flammenkamps website. Roughly speaking, for a number to be highly composite it has to have prime factors as small as possible, also, except in two special cases n =4 and n =36, the last exponent ck must equal 1. It means that 1,4, and 36 are the only square highly composite numbers, saying that the sequence of exponents is non-increasing is equivalent to saying that a highly composite number is a product of primorials. Note, that although the above described conditions are necessary, they are not sufficient for a number to be highly composite. For example,96 =25 ×3 satisfies the conditions and has 12 divisors but is not highly composite since there is a smaller number 60 which has the same number of divisors. If Q denotes the number of composite numbers less than or equal to x. The first part of the inequality was proved by Paul Erdős in 1944 and we have 1.13862 < lim inf log Q log log x ≤1.44 and lim sup log Q log log x ≤1.71. Highly composite numbers higher than 6 are also abundant numbers, one need only look at the three or four highest divisors of a particular highly composite number to ascertain this fact. It is false that all composite numbers are also Harshad numbers in base 10. The first HCN that is not a Harshad number is 245,044,800, which has a sum of 27. 10 of the first 38 highly composite numbers are highly composite numbers. The sequence of composite numbers is a subset of the sequence of smallest numbers k with exactly n divisors. A positive integer n is a composite number if d ≥ d for all m ≤ n. The counting function QL of largely composite numbers satisfies c ≤ log Q L ≤ d for positive c, d with 0.2 ≤ c ≤ d ≤0.5. Because the prime factorization of a composite number uses all of the first k primes
