Moscow
–
Moscow is the capital and most populous city of Russia, with 13.2 million residents within the city limits and 17.8 million within the urban area. Moscow has the status of a Russian federal city, Moscow is a major political, economic, cultural, and scientific center of Russia and Eastern Europe, as well as the largest city entirely on the European continent. Moscow is the northernmost and coldest megacity and metropolis on Earth and it is home to the Ostankino Tower, the tallest free standing structure in Europe, the Federation Tower, the tallest skyscraper in Europe, and the Moscow International Business Center. Moscow is situated on the Moskva River in the Central Federal District of European Russia, the city is well known for its architecture, particularly its historic buildings such as Saint Basils Cathedral with its brightly colored domes. Moscow is the seat of power of the Government of Russia, being the site of the Moscow Kremlin, the Moscow Kremlin and Red Square are also one of several World Heritage Sites in the city. Both chambers of the Russian parliament also sit in the city and it is recognized as one of the citys landmarks due to the rich architecture of its 200 stations. In old Russian the word also meant a church administrative district. The demonym for a Moscow resident is москвич for male or москвичка for female, the name of the city is thought to be derived from the name of the Moskva River. There have been proposed several theories of the origin of the name of the river and its cognates include Russian, музга, muzga pool, puddle, Lithuanian, mazgoti and Latvian, mazgāt to wash, Sanskrit, majjati to drown, Latin, mergō to dip, immerse. There exist as well similar place names in Poland like Mozgawa, the original Old Russian form of the name is reconstructed as *Москы, *Mosky, hence it was one of a few Slavic ū-stem nouns. From the latter forms came the modern Russian name Москва, Moskva, in a similar manner the Latin name Moscovia has been formed, later it became a colloquial name for Russia used in Western Europe in the 16th–17th centuries. From it as well came English Muscovy, various other theories, having little or no scientific ground, are now largely rejected by contemporary linguists. The surface similarity of the name Russia with Rosh, an obscure biblical tribe or country, the oldest evidence of humans on the territory of Moscow dates from the Neolithic. Within the modern bounds of the city other late evidence was discovered, on the territory of the Kremlin, Sparrow Hills, Setun River and Kuntsevskiy forest park, etc. The earliest East Slavic tribes recorded as having expanded to the upper Volga in the 9th to 10th centuries are the Vyatichi and Krivichi, the Moskva River was incorporated as part of Rostov-Suzdal into the Kievan Rus in the 11th century. By AD1100, a settlement had appeared on the mouth of the Neglinnaya River. The first known reference to Moscow dates from 1147 as a place of Yuri Dolgoruky. At the time it was a town on the western border of Vladimir-Suzdal Principality

Russia
–
Russia, also officially the Russian Federation, is a country in Eurasia. The European western part of the country is more populated and urbanised than the eastern. Russias capital Moscow is one of the largest cities in the world, other urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a range of environments. It shares maritime borders with Japan by the Sea of Okhotsk, the East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, in 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus ultimately disintegrated into a number of states, most of the Rus lands were overrun by the Mongol invasion. The Soviet Union played a role in the Allied victory in World War II. The Soviet era saw some of the most significant technological achievements of the 20th century, including the worlds first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the second largest economy, largest standing military in the world. It is governed as a federal semi-presidential republic, the Russian economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2015. Russias extensive mineral and energy resources are the largest such reserves in the world, making it one of the producers of oil. The country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction, Russia is a great power as well as a regional power and has been characterised as a potential superpower. The name Russia is derived from Rus, a state populated mostly by the East Slavs. However, this name became more prominent in the later history, and the country typically was called by its inhabitants Русская Земля. In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus by modern historiography, an old Latin version of the name Rus was Ruthenia, mostly applied to the western and southern regions of Rus that were adjacent to Catholic Europe. The current name of the country, Россия, comes from the Byzantine Greek designation of the Kievan Rus, the standard way to refer to citizens of Russia is Russians in English and rossiyane in Russian. There are two Russian words which are translated into English as Russians

Massachusetts Institute of Technology
–
The Massachusetts Institute of Technology is a private research university in Cambridge, Massachusetts, often cited as one of the worlds most prestigious universities. Researchers worked on computers, radar, and inertial guidance during World War II, post-war defense research contributed to the rapid expansion of the faculty and campus under James Killian. The current 168-acre campus opened in 1916 and extends over 1 mile along the bank of the Charles River basin. The Institute is traditionally known for its research and education in the sciences and engineering, and more recently in biology, economics, linguistics. Air Force and 6 Fields Medalists have been affiliated with MIT, the school has a strong entrepreneurial culture, and the aggregated revenues of companies founded by MIT alumni would rank as the eleventh-largest economy in the world. In 1859, a proposal was submitted to the Massachusetts General Court to use newly filled lands in Back Bay, Boston for a Conservatory of Art and Science, but the proposal failed. A charter for the incorporation of the Massachusetts Institute of Technology, Rogers, a professor from the University of Virginia, wanted to establish an institution to address rapid scientific and technological advances. The Rogers Plan reflected the German research university model, emphasizing an independent faculty engaged in research, as well as instruction oriented around seminars, two days after the charter was issued, the first battle of the Civil War broke out. After a long delay through the war years, MITs first classes were held in the Mercantile Building in Boston in 1865, in 1863 under the same act, the Commonwealth of Massachusetts founded the Massachusetts Agricultural College, which developed as the University of Massachusetts Amherst. In 1866, the proceeds from sales went toward new buildings in the Back Bay. MIT was informally called Boston Tech, the institute adopted the European polytechnic university model and emphasized laboratory instruction from an early date. Despite chronic financial problems, the institute saw growth in the last two decades of the 19th century under President Francis Amasa Walker. Programs in electrical, chemical, marine, and sanitary engineering were introduced, new buildings were built, the curriculum drifted to a vocational emphasis, with less focus on theoretical science. The fledgling school still suffered from chronic financial shortages which diverted the attention of the MIT leadership, during these Boston Tech years, MIT faculty and alumni rebuffed Harvard University president Charles W. Eliots repeated attempts to merge MIT with Harvard Colleges Lawrence Scientific School. There would be at least six attempts to absorb MIT into Harvard, in its cramped Back Bay location, MIT could not afford to expand its overcrowded facilities, driving a desperate search for a new campus and funding. Eventually the MIT Corporation approved an agreement to merge with Harvard, over the vehement objections of MIT faculty, students. However, a 1917 decision by the Massachusetts Supreme Judicial Court effectively put an end to the merger scheme, the neoclassical New Technology campus was designed by William W. Bosworth and had been funded largely by anonymous donations from a mysterious Mr. Smith, starting in 1912. In January 1920, the donor was revealed to be the industrialist George Eastman of Rochester, New York, who had invented methods of production and processing

Data science
–
Data science is a concept to unify statistics, data analysis and their related methods in order to understand and analyze actual phenomena with data. While many university programs now offer a data science degree, there exists no consensus on a definition or curriculum contents, because of the current popularity of this term, there are many advocacy efforts surrounding it. The term data science has existed for over thirty years and was used initially as a substitute for computer science by Peter Naur in 1960, in 1996, members of the International Federation of Classification Societies met in Kobe for their biennial conference. Here, for the first time, the data science is included in the title of the conference. Jeff Wu gave the inaugural lecture entitled Statistics = Data Science, for his appointment to the H. C. Carver Professorship at the University of Michigan. In this lecture, he characterized statistical work as a trilogy of data collection, data modeling and analysis, in his conclusion, he initiated the modern, non-computer science, usage of the term data science and advocated that statistics be renamed data science and statisticians data scientists. Later, he presented his lecture entitled Statistics = Data Science, as the first of his 1998 P. C. These lectures honor Prasanta Chandra Mahalanobis, an Indian scientist and statistician, in 2001, William S.1, of the April 2001 edition of the International Statistical Review / Revue Internationale de Statistique. Shortly thereafter, in January 2003, Columbia University began publishing The Journal of Data Science, the journal was largely devoted to the application of statistical methods and quantitative research. He asserts that a data scientist is a new breed, and that a shortage of scientists is becoming a serious constraint in some sectors. In 2015, the International Journal on Data Science and Analytics was launched by Springer to publish work on data science. 2013 the first European Conference on Data Analysis was organised in Luxembourg establishing the European Association for Data Science in August 2015. In September 2015 the Gesellschaft für Klassifikation added to the name of the Society Data Science Society at the third ECDA conference at the University of Essex, Colchester, UK. Although use of the data science has exploded in business environments, many academics. Data scientist is slightly redundant in some way and people shouldn’t berate the term statistician, universities are offering masters courses in data science. Shorter private bootcamps are also offering data science certificates including student-paid programs like General Assembly to employer-paid programs like The Data Incubator, in the 2010-2011 time frame, data science software reached an inflection point where open source software started supplanting proprietary software. The use of open source software enables modifying and extending the software, mining the Social Web, 2nd Edition

Artificial intelligence
–
Artificial intelligence is intelligence exhibited by machines. Colloquially, the artificial intelligence is applied when a machine mimics cognitive functions that humans associate with other human minds, such as learning. As machines become increasingly capable, mental facilities once thought to require intelligence are removed from the definition, for instance, optical character recognition is no longer perceived as an example of artificial intelligence, having become a routine technology. AI research is divided into subfields that focus on specific problems or on specific approaches or on the use of a tool or towards satisfying particular applications. The central problems of AI research include reasoning, knowledge, planning, learning, natural language processing, perception, general intelligence is among the fields long-term goals. Approaches include statistical methods, computational intelligence, and traditional symbolic AI, Many tools are used in AI, including versions of search and mathematical optimization, logic, methods based on probability and economics. The AI field draws upon computer science, mathematics, psychology, linguistics, philosophy, neuroscience, the field was founded on the claim that human intelligence can be so precisely described that a machine can be made to simulate it. Some people also consider AI a danger to humanity if it progresses unabatedly, while thought-capable artificial beings appeared as storytelling devices in antiquity, the idea of actually trying to build a machine to perform useful reasoning may have begun with Ramon Llull. With his Calculus ratiocinator, Gottfried Leibniz extended the concept of the calculating machine, since the 19th century, artificial beings are common in fiction, as in Mary Shelleys Frankenstein or Karel Čapeks R. U. R. The study of mechanical or formal reasoning began with philosophers and mathematicians in antiquity, in the 19th century, George Boole refined those ideas into propositional logic and Gottlob Frege developed a notational system for mechanical reasoning. Around the 1940s, Alan Turings theory of computation suggested that a machine, by shuffling symbols as simple as 0 and 1 and this insight, that digital computers can simulate any process of formal reasoning, is known as the Church–Turing thesis. Along with concurrent discoveries in neurology, information theory and cybernetics, the first work that is now generally recognized as AI was McCullouch and Pitts 1943 formal design for Turing-complete artificial neurons. The field of AI research was born at a conference at Dartmouth College in 1956, attendees Allen Newell, Herbert Simon, John McCarthy, Marvin Minsky and Arthur Samuel became the founders and leaders of AI research. At the conference, Newell and Simon, together with programmer J. C, shaw, presented the first true artificial intelligence program, the Logic Theorist. This spurred tremendous research in the domain, computers were winning at checkers, solving problems in algebra, proving logical theorems. By the middle of the 1960s, research in the U. S. was heavily funded by the Department of Defense and laboratories had been established around the world. AIs founders were optimistic about the future, Herbert Simon predicted, machines will be capable, within twenty years, Marvin Minsky agreed, writing, within a generation. The problem of creating artificial intelligence will substantially be solved and they failed to recognize the difficulty of some of the remaining tasks

Engineering
–
The term Engineering is derived from the Latin ingenium, meaning cleverness and ingeniare, meaning to contrive, devise. Engineering has existed since ancient times as humans devised fundamental inventions such as the wedge, lever, wheel, each of these inventions is essentially consistent with the modern definition of engineering. The term engineering is derived from the engineer, which itself dates back to 1390 when an engineer originally referred to a constructor of military engines. In this context, now obsolete, a referred to a military machine. Notable examples of the obsolete usage which have survived to the present day are military engineering corps, the word engine itself is of even older origin, ultimately deriving from the Latin ingenium, meaning innate quality, especially mental power, hence a clever invention. The earliest civil engineer known by name is Imhotep, as one of the officials of the Pharaoh, Djosèr, he probably designed and supervised the construction of the Pyramid of Djoser at Saqqara in Egypt around 2630–2611 BC. Ancient Greece developed machines in both civilian and military domains, the Antikythera mechanism, the first known mechanical computer, and the mechanical inventions of Archimedes are examples of early mechanical engineering. In the Middle Ages, the trebuchet was developed, the first steam engine was built in 1698 by Thomas Savery. The development of this gave rise to the Industrial Revolution in the coming decades. With the rise of engineering as a profession in the 18th century, similarly, in addition to military and civil engineering, the fields then known as the mechanic arts became incorporated into engineering. The inventions of Thomas Newcomen and the Scottish engineer James Watt gave rise to mechanical engineering. The development of specialized machines and machine tools during the revolution led to the rapid growth of mechanical engineering both in its birthplace Britain and abroad. John Smeaton was the first self-proclaimed civil engineer and is regarded as the father of civil engineering. He was an English civil engineer responsible for the design of bridges, canals, harbours and he was also a capable mechanical engineer and an eminent physicist. Smeaton designed the third Eddystone Lighthouse where he pioneered the use of hydraulic lime and his lighthouse remained in use until 1877 and was dismantled and partially rebuilt at Plymouth Hoe where it is known as Smeatons Tower. The United States census of 1850 listed the occupation of engineer for the first time with a count of 2,000, there were fewer than 50 engineering graduates in the U. S. before 1865. In 1870 there were a dozen U. S. mechanical engineering graduates, in 1890 there were 6,000 engineers in civil, mining, mechanical and electrical. There was no chair of applied mechanism and applied mechanics established at Cambridge until 1875, the theoretical work of James Maxwell and Heinrich Hertz in the late 19th century gave rise to the field of electronics

Efficient energy use
–
Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to achieve, installing fluorescent lights, LED lights or natural skylights reduces the amount of energy required to attain the same level of illumination compared with using traditional incandescent light bulbs. Improvements in energy efficiency are generally achieved by adopting an efficient technology or production process or by application of commonly accepted methods to reduce energy losses. There are many motivations to improve energy efficiency, reducing energy use reduces energy costs and may result in a financial cost saving to consumers if the energy savings offset any additional costs of implementing an energy efficient technology. Reducing energy use is seen as a solution to the problem of reducing greenhouse gas emissions. Energy efficiency and renewable energy are said to be the pillars of sustainable energy policy and are high priorities in the sustainable energy hierarchy. Energy efficiency has proved to be a strategy for building economies without necessarily increasing energy consumption. For example, the state of California began implementing energy-efficiency measures in the mid-1970s, including building code, during the following years, Californias energy consumption has remained approximately flat on a per capita basis while national US consumption doubled. In general, up to 75% of the electricity used in the US today could be saved with efficiency measures that cost less than the electricity itself. The same holds true for this is home and there is 78% of electricity uses D in your home-owners, in fact, researchers at the US Department of Energy and their consortium, Residential Energy Efficient Distribution Systems have found that duct efficiency may be as low as 50–70%. The US Department of Energy has stated there is potential for energy saving in the magnitude of 90 Billion kWh by increasing home energy efficiency. Other studies have emphasized this.2 percent average growth anticipated through 2020 in a business-as-usual scenario, international standards ISO17743 and ISO17742 provide a documented methodology for calculating and reporting on energy savings and energy efficiency for countries and cities. Modern appliances, such as, freezers, ovens, stoves, dishwashers, installing a clothesline will significantly reduce ones energy consumption as their dryer will be used less. Current energy efficient refrigerators, for example, use 40 percent less energy than conventional models did in 2001, in the US, the corresponding figures would be 17 billion kWh of electricity and 27,000,000,000 lb CO2. According to a 2009 study from McKinsey & Company the replacement of old appliances is one of the most efficient global measures to reduce emissions of greenhouse gases. Modern power management systems also reduce energy usage by idle appliances by turning them off or putting them into a low-energy mode after a certain time, many countries identify energy-efficient appliances using energy input labeling. The impact of energy efficiency on peak demand depends on when the appliance is used, for example, an air conditioner uses more energy during the afternoon when it is hot. Therefore, an efficient air conditioner will have a larger impact on peak demand than off-peak demand

Skolkovo, Moscow Oblast
–
Skolkovo is a rural locality in Odintsovsky District of Moscow Oblast, Russia, located 2 kilometers west of MKAD near the Setun River. The village has known since the 16th century. In 1862, the population of the lived in 23 homesteads comprising 226 people. In March 2010, Russian President Dmitry Medvedev announced plans to create Skolkovo innovation center—a modern technology complex to encourage scientific research, the construction of the center is expected to start in the vicinity of Skolkovo in 2011. Currently, another major project is realized near Skolkovo - the construction of the campus of Skolkovo Moscow School of Management, Сколково — непростая история небольшого села

Doctor of Philosophy
–
A Doctor of Philosophy is a type of doctoral degree awarded by universities in many countries. Ph. D. s are awarded for a range of programs in the sciences, engineering. The Ph. D. is a degree in many fields. The completion of a Ph. D. is often a requirement for employment as a university professor, researcher, individuals with an earned doctorate can use the title of Doctor with their name and use the post-nominal letters Ph. D. The requirements to earn a Ph. D. degree vary considerably according to the country, institution, a person who attains a doctorate of philosophy is automatically awarded the academic title of doctor. A student attaining this level may be granted a Candidate of Philosophy degree at some institutions. A Ph. D. candidate must submit a project, thesis or dissertation often consisting of a body of academic research. In many countries, a candidate must defend this work before a panel of examiners appointed by the university. Universities award other types of doctorates besides the Ph. D. such as the Doctor of Musical Arts, a degree for music performers and the Doctor of Education, in 2016, ELIA launched The Florence Principles on the Doctorate in the Arts. The Florence Principles have been endorsed are supported also by AEC, CILECT, CUMULUS, the degree is abbreviated PhD, from the Latin Philosophiae Doctor, pronounced as three separate letters. In the universities of Medieval Europe, study was organized in four faculties, the faculty of arts. All of these faculties awarded intermediate degrees and final degrees, the doctorates in the higher faculties were quite different from the current Ph. D. degree in that they were awarded for advanced scholarship, not original research. No dissertation or original work was required, only lengthy residency requirements, besides these degrees, there was the licentiate. According to Keith Allan Noble, the first doctoral degree was awarded in medieval Paris around 1150, the doctorate of philosophy developed in Germany as the terminal Teachers credential in the 17th century. Typically, upon completion, the candidate undergoes an oral examination, always public, starting in 2016, in Ukraine Doctor of Philosophy is the highest education level and the first science degree. PhD is awarded in recognition of a contribution to scientific knowledge. A PhD degree is a prerequisite for heading a university department in Ukraine, upon completion of a PhD, a PhD holder can elect to continue his studies and get a post-doctoral degree called Doctor of Sciences, which is the second and the highest science degree in Ukraine. Scandinavian countries were among the early adopters of a known as a doctorate of philosophy

Petroleum engineering
–
For petroleum refinery engineering, see Process engineering. Petroleum engineering is a field of engineering concerned with the related to the production of hydrocarbons. Exploration and Production are deemed to fall within the sector of the oil. Recruitment to the industry has historically been from the disciplines of physics, subsequent development training has usually been done within oil companies. The profession got its start in 1914 within the American Institute of Mining, Metallurgical, the first Petroleum Engineering degree was conferred in 1915 by the University of Pittsburgh. Since then, the profession has evolved to solve increasingly difficult situations, as much of the low hanging fruit of the oil fields have been found. Deep-water, arctic and desert conditions are usually contended with, the Society of Petroleum Engineers is the largest professional society for petroleum engineers and publishes much information concerning the industry. Petroleum engineering has historically been one of the highest paid engineering disciplines, in a June 4,2007 article, Forbes. com reported that petroleum engineering was the 24th best paying job in the United States. The 2010 National Association of Colleges and Employers survey showed petroleum engineers as the highest paid 2010 graduates at an average $125,220 annual salary, for individuals with experience, salaries can go from $170,000 to $260,000 annually. They make an average of $112,000 a year and about $53.75 per hour, Petroleum engineers divide themselves into several types, Reservoir engineers work to optimize production of oil and gas via proper placement, production rates, and enhanced oil recovery techniques. Drilling engineers manage the technical aspects of drilling exploratory, production and injection wells, Petroleum Engineering - Best Petroleum Engineering Schools & Colleges, Jobs in USA About Petroleum Engineering Career Opportunities in Petroleum Engineering

Photonics
–
Photonics is the physical science of light generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification, and detection/sensing. Though covering all lights technical applications over the spectrum, most photonic applications are in the range of visible. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s, Photonics as a field began with the invention of the laser in 1960. Other developments followed, the diode in the 1970s, optical fibers for transmitting information. These inventions formed the basis for the revolution of the late 20th century. Though coined earlier, the term came into common use in the 1980s as fiber-optic data transmission was adopted by telecommunications network operators. At that time, the term was used widely at Bell Laboratories and its use was confirmed when the IEEE Lasers and Electro-Optics Society established an archival journal named Photonics Technology Letters at the end of the 1980s. During the period leading up to the dot-com crash circa 2001, further growth of photonics is likely if current silicon photonics developments are successful. Photonics is closely related to optics, classical optics long preceded the discovery that light is quantized, when Albert Einstein famously explained the photoelectric effect in 1905. Optics tools include the lens, the reflecting mirror. Photonics is related to optics, optomechanics, electro-optics, optoelectronics. However, each area has different connotations by scientific and government communities. Quantum optics often connotes fundamental research, whereas photonics is used to connote applied research, the term optoelectronics connotes devices or circuits that comprise both electrical and optical functions, i. e. a thin-film semiconductor device. Photonics also relates to the science of quantum information and quantum optics. Included are all areas from everyday life to the most advanced science, just as applications of electronics have expanded dramatically since the first transistor was invented in 1948, the unique applications of photonics continue to emerge. The science of photonics includes investigation of the emission, transmission, amplification, detection, light sources used in photonics are usually far more sophisticated than light bulbs. Photonics commonly uses semiconductor light sources like light-emitting diodes, superluminescent diodes, other light sources include single photon sources, fluorescent lamps, cathode ray tubes, and plasma screens. Characteristic for research on semiconductor light sources is the frequent use of III-V semiconductors instead of the classical semiconductors like silicon and this is due to the special properties of III-V semiconductors that allow for the implementation of light emitting devices

Theoretical physics
–
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to physics, which uses experimental tools to probe these phenomena. The advancement of science depends in general on the interplay between experimental studies and theory, in some cases, theoretical physics adheres to standards of mathematical rigor while giving little weight to experiments and observations. Conversely, Einstein was awarded the Nobel Prize for explaining the photoelectric effect, a physical theory is a model of physical events. It is judged by the extent to which its predictions agree with empirical observations, the quality of a physical theory is also judged on its ability to make new predictions which can be verified by new observations. A physical theory similarly differs from a theory, in the sense that the word theory has a different meaning in mathematical terms. A physical theory involves one or more relationships between various measurable quantities, archimedes realized that a ship floats by displacing its mass of water, Pythagoras understood the relation between the length of a vibrating string and the musical tone it produces. Other examples include entropy as a measure of the uncertainty regarding the positions and motions of unseen particles, Theoretical physics consists of several different approaches. In this regard, theoretical particle physics forms a good example, for instance, phenomenologists might employ empirical formulas to agree with experimental results, often without deep physical understanding. Modelers often appear much like phenomenologists, but try to model speculative theories that have certain desirable features, some attempt to create approximate theories, called effective theories, because fully developed theories may be regarded as unsolvable or too complicated. Other theorists may try to unify, formalise, reinterpret or generalise extant theories, or create completely new ones altogether. Sometimes the vision provided by pure mathematical systems can provide clues to how a system might be modeled, e. g. the notion, due to Riemann and others. Theoretical problems that need computational investigation are often the concern of computational physics, Theoretical advances may consist in setting aside old, incorrect paradigms or may be an alternative model that provides answers that are more accurate or that can be more widely applied. In the latter case, a correspondence principle will be required to recover the previously known result, sometimes though, advances may proceed along different paths. However, an exception to all the above is the wave–particle duality, Physical theories become accepted if they are able to make correct predictions and no incorrect ones. They are also likely to be accepted if they connect a wide range of phenomena. Testing the consequences of a theory is part of the scientific method, Physical theories can be grouped into three categories, mainstream theories, proposed theories and fringe theories. Theoretical physics began at least 2,300 years ago, under the Pre-socratic philosophy, during the Middle Ages and Renaissance, the concept of experimental science, the counterpoint to theory, began with scholars such as Ibn al-Haytham and Francis Bacon

Biotechnology
–
Depending on the tools and applications, it often overlaps with the fields of bioengineering, biomedical engineering, biomanufacturing, molecular engineering, etc. For thousands of years, humankind has used biotechnology in agriculture, food production, the term is largely believed to have been coined in 1919 by Hungarian engineer Károly Ereky. Modern usage also includes genetic engineering as well as cell and tissue culture technologies, as per European Federation of Biotechnology, biotechnology is the integration of natural science and organisms, cells, parts thereof, and molecular analogues for products and services. Biotechnology also writes on the biological sciences. By contrast, bioengineering is generally thought of as a field that more heavily emphasizes higher systems approaches for interfacing with. Bioengineering is the application of the principles of engineering and natural sciences to tissues, cells and this can be considered as the use of knowledge from working with and manipulating biology to achieve a result that can improve functions in plants and animals. Although not normally what first comes to mind, many forms of human-derived agriculture clearly fit the definition of utilizing a biotechnological system to make products. Indeed, the cultivation of plants may be viewed as the earliest biotechnological enterprise, Agriculture has been theorized to have become the dominant way of producing food since the Neolithic Revolution. Through early biotechnology, the earliest farmers selected and bred the best suited crops, having the highest yields and these processes also were included in early fermentation of beer. These processes were introduced in early Mesopotamia, Egypt, China and India, in brewing, malted grains convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in the grains were broken down into alcohols such as ethanol, later other cultures produced the process of lactic acid fermentation which allowed the fermentation and preservation of other forms of food, such as soy sauce. Fermentation was also used in time period to produce leavened bread. Although the process of fermentation was not fully understood until Louis Pasteurs work in 1857, before the time of Charles Darwins work and life, animal and plant scientists had already used selective breeding. Darwin added to body of work with his scientific observations about the ability of science to change species. These accounts contributed to Darwins theory of natural selection, for thousands of years, humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics, for example, this technique was used with corn to produce the largest and sweetest crops. In the early twentieth century scientists gained an understanding of microbiology. Biotechnology has also led to the development of antibiotics, in 1928, Alexander Fleming discovered the mold Penicillium

Systems engineering
–
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles. At its core systems engineering utilizes systems thinking principles to organize this body of knowledge, Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects. Systems engineering ensures that all aspects of a project or system are considered. The systems engineering process is a process that is quite unlike a manufacturing process. A manufacturing process is focused on activities that achieve high quality outputs with minimum cost. The term systems engineering can be traced back to Bell Telephone Laboratories in the 1940s. S, the continuing evolution of systems engineering comprises the development and identification of new methods and modeling techniques. These methods aid in the comprehension and the design and development control of engineering systems as they grow more complex. Popular tools that are used in the systems engineering context were developed during these times, including USL, UML, QFD. In 1990, a society for systems engineering, the National Council on Systems Engineering, was founded by representatives from a number of U. S. corporations and organizations. NCOSE was created to address the need for improvements in engineering practices. As a result of growing involvement from systems engineers outside of the U. S. the name of the organization was changed to the International Council on Systems Engineering in 1995. Schools in several countries offer programs in systems engineering. Systems engineering signifies only an approach and, more recently, a discipline in engineering, as an approach, systems engineering is holistic and interdisciplinary in flavour. The traditional scope of engineering embraces the conception, design, development, Systems engineering, as originally conceived, falls within this scope. The Apollo program is an example of a systems engineering project. The use of the systems engineer has evolved over time to embrace a wider, more holistic concept of systems. This evolution of the definition has been a subject of ongoing controversy, traditional systems engineering was seen as a branch of engineering in the classical sense, that is, as applied only to physical system, such as space craft and aircraft. More recently, systems engineering has evolved to a take on a broader meaning especially when humans were seen as a component of a system

The interdisciplinary field of materials science, also commonly termed materials science and engineering, involves the discovery and design of new materials, with an emphasis on solids. Materials science still incorporates elements of physics, chemistry, and engineering, as such, the field was long considered by academic institutions as a sub-field of these related fields. Materials science is a syncretic discipline hybridizing metallurgy, ceramics, solid-state physics and it is the first example of a new academic discipline emerging by fusion rather than fission. Many of the most pressing scientific problems humans currently face are due to the limits of the materials that are available, thus, breakthroughs in materials science are likely to affect the future of technology significantly. Materials scientists emphasize understanding how the history of a material influences its structure, the understanding of processing-structure-properties relationships is called the § materials paradigm. This paradigm is used to advance understanding in a variety of areas, including nanotechnology, biomaterials. Such investigations are key to understanding, for example, the causes of various accidents and incidents. The material of choice of a given era is often a defining point, phrases such as Stone Age, Bronze Age, Iron Age, and Steel Age are great examples. Originally deriving from the manufacture of ceramics and its putative derivative metallurgy, materials science is one of the oldest forms of engineering, modern materials science evolved directly from metallurgy, which itself evolved from mining and ceramics and the use of fire. Materials science has driven, and been driven by, the development of technologies such as rubbers, plastics, semiconductors. Before the 1960s, many materials science departments were named metallurgy departments, reflecting the 19th, a material is defined as a substance that is intended to be used for certain applications. There are a myriad of materials around us—they can be found in anything from buildings to spacecraft, Materials can generally be divided into two classes, crystalline and non-crystalline. The traditional examples of materials are metals, semiconductors, ceramics, New and advanced materials that are being developed include nanomaterials and biomaterials, etc. The basis of science involves studying the structure of materials. Once a materials scientist knows about this structure-property correlation, they can go on to study the relative performance of a material in a given application. The major determinants of the structure of a material and thus of its properties are its constituent chemical elements and these characteristics, taken together and related through the laws of thermodynamics and kinetics, govern a materials microstructure, and thus its properties. As mentioned above, structure is one of the most important components of the field of materials science, Materials science examines the structure of materials from the atomic scale, all the way up to the macro scale. Characterization is the way materials scientists examine the structure of a material, structure is studied at various levels, as detailed below

Mathematics

Mathematics is the study of topics such as quantity, structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope, Mathematicians seek out patterns and use them to formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof, when mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry, rigorous arguments first appeared in Greek mathematics, most notably in Euclids Elements. Galileo Galilei said, The universe cannot be read until we have learned the language and it is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth, carl Friedrich Gauss referred to mathematics as the Queen of the Sciences. Benjamin Peirce called mathematics the science that draws necessary conclusions, David Hilbert said of mathematics, We are not speaking here of arbitrariness in any sense. Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules, rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise. Albert Einstein stated that as far as the laws of mathematics refer to reality, they are not certain, Mathematics is essential in many fields, including natural science, engineering, medicine, finance and the social sciences. Applied mathematics has led to entirely new mathematical disciplines, such as statistics, Mathematicians also engage in pure mathematics, or mathematics for its own sake, without having any application in mind. There is no clear line separating pure and applied mathematics, the history of mathematics can be seen as an ever-increasing series of abstractions. The earliest uses of mathematics were in trading, land measurement, painting and weaving patterns, in Babylonian mathematics elementary arithmetic first appears in the archaeological record. Numeracy pre-dated writing and numeral systems have many and diverse. Between 600 and 300 BC the Ancient Greeks began a study of mathematics in its own right with Greek mathematics. Mathematics has since been extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both. Mathematical discoveries continue to be made today, the overwhelming majority of works in this ocean contain new mathematical theorems and their proofs. The word máthēma is derived from μανθάνω, while the modern Greek equivalent is μαθαίνω, in Greece, the word for mathematics came to have the narrower and more technical meaning mathematical study even in Classical times

Mechanics
–
Mechanics is an area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. The scientific discipline has its origins in Ancient Greece with the writings of Aristotle, during the early modern period, scientists such as Khayaam, Galileo, Kepler, and Newton, laid the foundation for what is now known as classical mechanics. It is a branch of physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as a branch of science which deals with the motion of, historically, classical mechanics came first, while quantum mechanics is a comparatively recent invention. Classical mechanics originated with Isaac Newtons laws of motion in Philosophiæ Naturalis Principia Mathematica, both are commonly held to constitute the most certain knowledge that exists about physical nature. Classical mechanics has especially often been viewed as a model for other so-called exact sciences, essential in this respect is the relentless use of mathematics in theories, as well as the decisive role played by experiment in generating and testing them. Quantum mechanics is of a scope, as it encompasses classical mechanics as a sub-discipline which applies under certain restricted circumstances. According to the principle, there is no contradiction or conflict between the two subjects, each simply pertains to specific situations. The correspondence principle states that the behavior of systems described by quantum theories reproduces classical physics in the limit of quantum numbers. Quantum mechanics has superseded classical mechanics at the level and is indispensable for the explanation and prediction of processes at the molecular, atomic. However, for macroscopic processes classical mechanics is able to solve problems which are difficult in quantum mechanics and hence remains useful. Modern descriptions of such behavior begin with a definition of such quantities as displacement, time, velocity, acceleration, mass. Until about 400 years ago, however, motion was explained from a different point of view. He showed that the speed of falling objects increases steadily during the time of their fall and this acceleration is the same for heavy objects as for light ones, provided air friction is discounted. The English mathematician and physicist Isaac Newton improved this analysis by defining force and mass, for objects traveling at speeds close to the speed of light, Newton’s laws were superseded by Albert Einstein’s theory of relativity. For atomic and subatomic particles, Newton’s laws were superseded by quantum theory, for everyday phenomena, however, Newton’s three laws of motion remain the cornerstone of dynamics, which is the study of what causes motion. In analogy to the distinction between quantum and classical mechanics, Einsteins general and special theories of relativity have expanded the scope of Newton, the differences between relativistic and Newtonian mechanics become significant and even dominant as the velocity of a massive body approaches the speed of light. Relativistic corrections are also needed for quantum mechanics, although general relativity has not been integrated, the two theories remain incompatible, a hurdle which must be overcome in developing a theory of everything
