Stockholm
–
The city is spread across 14 islands on the coast in the southeast of Sweden at the mouth of Lake Mälaren, by the Stockholm archipelago and the Baltic Sea. The area has settled since the Stone Age, in the 6th millennium BC. It is also the capital of Stockholm County, Stockholm is the cultural, media, political, and economic centre of Sweden. The Stockholm region alone accounts for over a third of the countrys GDP and it is an important global city, and the main centre for corporate headquarters in the Nordic region. The city is home to some of Europes top ranking universities, such as the Stockholm School of Economics, Karolinska Institute and it hosts the annual Nobel Prize ceremonies and banquet at the Stockholm Concert Hall and Stockholm City Hall. One of the citys most prized museums, the Vasa Museum, is the most visited museum in Scandinavia. The Stockholm metro, opened in 1950, is known for its decoration of the stations. Swedens national football arena is located north of the city centre, Ericsson Globe, the national indoor arena, is in the southern part of the city. The city was the host of the 1912 Summer Olympics, and hosted the equestrian portion of the 1956 Summer Olympics otherwise held in Melbourne, Victoria, Australia. Stockholm is the seat of the Swedish government and most of its agencies, including the highest courts in the judiciary, and the official residencies of the Swedish monarch and the Prime Minister. The government has its seat in the Rosenbad building, the Riksdag is seated in the Parliament House, and the Prime Ministers residence is adjacent at the Sager House. After the Ice Age, around 8,000 BCE, there were already a number of people living in the present-day Stockholm area. Thousands of years later, as the ground thawed, the climate became tolerable, at the intersection of the Baltic Sea and lake Mälaren is an archipelago site where the Old Town of Stockholm was first built from about 1000 CE by Vikings. They had a positive impact on the area because of the trade routes they created. Stockholms location appears in Norse sagas as Agnafit, and in Heimskringla in connection with the legendary king Agne, the earliest written mention of the name Stockholm dates from 1252, by which time the mines in Bergslagen made it an important site in the iron trade. The first part of the name means log in Swedish, although it may also be connected to an old German word meaning fortification, the second part of the name means islet, and is thought to refer to the islet Helgeandsholmen in central Stockholm. Stockholms core, the present Old Town was built on the island next to Helgeandsholmen from the mid 13th century onward. The city originally rose to prominence as a result of the Baltic trade of the Hanseatic League, Stockholm developed strong economic and cultural linkages with Lübeck, Hamburg, Gdańsk, Visby, Reval, and Riga during this time

John Bardeen
–
Bardeens developments in superconductivity, which won him his second Nobel, are used in Nuclear Magnetic Resonance Spectroscopy or its medical sub-tool magnetic resonance imaging. In 1990, John Bardeen appeared on LIFE Magazines list of 100 Most Influential Americans of the Century, John Bardeen was born in Madison, Wisconsin on May 23,1908. He was the son of Charles Russell Bardeen, the first dean of the University of Wisconsin Medical School, Bardeen attended the University High School at Madison for several years, but graduated from Madison Central High School in 1923. He graduated from school at age fifteen, even though he could have graduated several years earlier. His graduation was postponed due to taking courses at another high school. He entered the University of Wisconsin–Madison in 1923, while in college he joined the Zeta Psi fraternity. He raised the membership fees partly by playing billiards. He was initiated as a member of Tau Beta Pi engineering honor society and he chose engineering because he didnt want to be an academic like his father and also because it is mathematical. He also felt that engineering had good job prospects, Bardeen received his Bachelor of Science degree in electrical engineering in 1928 from the University of Wisconsin–Madison. He graduated in 1928 despite taking a year off during his degree to work in Chicago and he received his Master of Science degree in electrical engineering in 1929 from Wisconsin. Bardeen stayed on for time at Wisconsin furthering his studies, but he eventually went to work for Gulf Research Laboratories. From 1930 to 1933, Bardeen worked there on the development of methods for the interpretation of magnetic, after the work failed to keep his interest, he applied and was accepted to the graduate program in mathematics at Princeton University. Bardeen studied both mathematics and physics as a student, ending up writing his thesis on a problem in solid-state physics. Before completing his thesis, he was offered a position as Junior Fellow of the Society of Fellows at Harvard University in 1935 and he received his Ph. D. in mathematical physics from Princeton in 1936. In October 1945, John Bardeen began work at Bell Labs, Bardeen was a member of a Solid State Physics Group, led by William Shockley and chemist Stanley Morgan. Other personnel working in the group were Walter Brattain, physicist Gerald Pearson, chemist Robert Gibney, electronics expert Hilbert Moore and he moved his family to Summit, New Jersey. The assignment of the group was to seek an alternative to fragile glass vacuum tube amplifiers. Their first attempts were based on Shockleys ideas about using an electrical field on a semiconductor to affect its conductivity

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

Nobel Prize
–
The Nobel Prize is a set of annual international awards bestowed in a number of categories by Swedish and Norwegian institutions in recognition of academic, cultural, or scientific advances. The will of the Swedish inventor Alfred Nobel established the prizes in 1895, the prizes in Chemistry, Literature, Peace, Physics, and Physiology or Medicine were first awarded in 1901. Medals made before 1980 were struck in 23 carat gold, between 1901 and 2016, the Nobel Prizes and the Prize in Economic Sciences were awarded 579 times to 911 people and organisations. With some receiving the Nobel Prize more than once, this makes a total of 23 organisations, the prize ceremonies take place annually in Stockholm, Sweden. Each recipient, or laureate, receives a medal, a diploma. The Nobel Prize is widely regarded as the most prestigious award available in the fields of literature, medicine, physics, chemistry, peace, and economics. The prize is not awarded posthumously, however, if a person is awarded a prize and dies before receiving it, though the average number of laureates per prize increased substantially during the 20th century, a prize may not be shared among more than three people. Alfred Nobel was born on 21 October 1833 in Stockholm, Sweden and he was a chemist, engineer, and inventor. In 1894, Nobel purchased the Bofors iron and steel mill and this invention was a precursor to many smokeless military explosives, especially the British smokeless powder cordite. As a consequence of his patent claims, Nobel was eventually involved in a patent infringement lawsuit over cordite, Nobel amassed a fortune during his lifetime, with most of his wealth from his 355 inventions, of which dynamite is the most famous. In 1888, Nobel was astonished to read his own obituary, titled The merchant of death is dead, as it was Alfreds brother Ludvig who had died, the obituary was eight years premature. The article disconcerted Nobel and made him apprehensive about how he would be remembered and this inspired him to change his will. On 10 December 1896, Alfred Nobel died in his villa in San Remo, Italy, Nobel wrote several wills during his lifetime. He composed the last over a year before he died, signing it at the Swedish–Norwegian Club in Paris on 27 November 1895, Nobel bequeathed 94% of his total assets,31 million SEK, to establish the five Nobel Prizes. Because of skepticism surrounding the will, it was not until 26 April 1897 that it was approved by the Storting in Norway. The executors of Nobels will, Ragnar Sohlman and Rudolf Lilljequist, formed the Nobel Foundation to take care of Nobels fortune, Nobels instructions named a Norwegian Nobel Committee to award the Peace Prize, the members of whom were appointed shortly after the will was approved in April 1897. Soon thereafter, the other prize-awarding organisations were designated or established and these were Karolinska Institutet on 7 June, the Swedish Academy on 9 June, and the Royal Swedish Academy of Sciences on 11 June. The Nobel Foundation reached an agreement on guidelines for how the prizes should be awarded, and, in 1900, in 1905, the personal union between Sweden and Norway was dissolved

X-ray
–
X-radiation is a form of electromagnetic radiation. Most X-rays have a wavelength ranging from 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz, X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. Spelling of X-ray in the English language includes the variants x-ray, xray, X-rays with high photon energies are called hard X-rays, while those with lower energy are called soft X-rays. Due to their ability, hard X-rays are widely used to image the inside of objects, e. g. in medical radiography. The term X-ray is metonymically used to refer to an image produced using this method. Since the wavelengths of hard X-rays are similar to the size of atoms they are useful for determining crystal structures by X-ray crystallography. By contrast, soft X-rays are easily absorbed in air, the length of 600 eV X-rays in water is less than 1 micrometer. There is no consensus for a definition distinguishing between X-rays and gamma rays, one common practice is to distinguish between the two types of radiation based on their source, X-rays are emitted by electrons, while gamma rays are emitted by the atomic nucleus. This definition has problems, other processes also can generate these high-energy photons. One common alternative is to distinguish X- and gamma radiation on the basis of wavelength, with radiation shorter than some arbitrary wavelength, such as 10−11 m and this criterion assigns a photon to an unambiguous category, but is only possible if wavelength is known. Occasionally, one term or the other is used in specific contexts due to precedent, based on measurement technique. Thus, gamma-rays generated for medical and industrial uses, for radiotherapy, in the ranges of 6–20 MeV. X-ray photons carry enough energy to ionize atoms and disrupt molecular bonds and this makes it a type of ionizing radiation, and therefore harmful to living tissue. A very high radiation dose over a period of time causes radiation sickness. In medical imaging this increased risk is generally greatly outweighed by the benefits of the examination. The ionizing capability of X-rays can be utilized in treatment to kill malignant cells using radiation therapy. It is also used for material characterization using X-ray spectroscopy, hard X-rays can traverse relatively thick objects without being much absorbed or scattered. For this reason, X-rays are widely used to image the inside of visually opaque objects, the most often seen applications are in medical radiography and airport security scanners, but similar techniques are also important in industry and research

Marie Curie
–
Marie Skłodowska Curie, born Maria Salomea Skłodowska, was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was also the first woman to become a professor at the University of Paris and she was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaws clandestine Floating University and began her scientific training in Warsaw. In 1891, aged 24, she followed her older sister Bronisława to study in Paris and she shared the 1903 Nobel Prize in Physics with her husband Pierre Curie and with physicist Henri Becquerel. She won the 1911 Nobel Prize in Chemistry and her achievements included the development of the theory of radioactivity, techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the worlds first studies were conducted into the treatment of neoplasms and she founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. During World War I, she developed mobile radiography units to provide X-ray services to field hospitals, while a French citizen, Marie Skłodowska Curie never lost her sense of Polish identity. She taught her daughters the Polish language and took them on visits to Poland and she named the first chemical element that she discovered—polonium, which she isolated in 1898—after her native country. Maria Skłodowska was born in Warsaw, in the Russian partition of Poland, on 7 November 1867, the fifth and youngest child of well-known teachers Bronisława, née Boguska, the elder siblings of Maria were Zofia, Józef, Bronisława and Helena. On both the paternal and maternal sides, the family had lost their property and fortunes through patriotic involvements in Polish national uprisings aimed at restoring Polands independence. This condemned the subsequent generation, including Maria, her sisters and her brother. Marias paternal grandfather, Józef Skłodowski, had been a teacher in Lublin, where he taught the young Bolesław Prus. Her father, Władysław Skłodowski, taught mathematics and physics, subjects that Maria was to pursue, after Russian authorities eliminated laboratory instruction from the Polish schools, he brought much of the laboratory equipment home, and instructed his children in its use. Marias mother Bronisława operated a prestigious Warsaw boarding school for girls and she died of tuberculosis in May 1878, when Maria was ten years old. Less than three years earlier, Marias oldest sibling, Zofia, had died of typhus contracted from a boarder, Marias father was an atheist, her mother a devout Catholic. The deaths of Marias mother and sister caused her to give up Catholicism and become agnostic. When she was ten years old, Maria began attending the school of J. Sikorska, next she attended a gymnasium for girls. After a collapse, possibly due to depression, she spent the year in the countryside with relatives of her father, and the next year with her father in Warsaw

Maria Goeppert-Mayer
–
Maria Goeppert Mayer was a German-born American theoretical physicist, and Nobel laureate in Physics for proposing the nuclear shell model of the atomic nucleus. She was the second female Nobel laureate in physics, after Marie Curie, a graduate of the University of Göttingen, Goeppert Mayer wrote her doctorate on the theory of possible two-photon absorption by atoms. At the time, the chances of experimentally verifying her thesis seemed remote, today, the unit for the two-photon absorption cross section is named the Goeppert Mayer unit. Maria Goeppert married Joseph Edward Mayer and moved to the United States, in 1937, she moved to Columbia University, where she took an unpaid position. During World War II, she worked for the Manhattan Project at Columbia on isotope separation, after the war, Goeppert Mayer became a voluntary associate professor of Physics at the University of Chicago and a senior physicist at the nearby Argonne National Laboratory. She developed a model for the structure of nuclear shells, for which she was awarded the Nobel Prize in Physics in 1963. In 1960, she was appointed professor of physics at the University of California. Maria Göppert was born on June 28,1906, in Kattowitz, a city in Prussia, in 1910, she moved with her family to Göttingen when her father, a sixth-generation university professor, was appointed as the professor of pediatrics at the University of Göttingen. Goeppert was closer to her father than her mother, well, my father was more interesting, she later explained. He was after all a scientist, Göppert was educated at the Höhere Technische in Göttingen, a school for middle-class girls who aspired to higher education. In 1921, she entered the Frauenstudium, a high school run by suffragettes that aimed to prepare girls for university. She took the abitur, the university examination, at age 17. All the girls passed, but only one of the boys did, in the Spring of 1924, Göppert entered the University of Göttingen, where she studied mathematics. Instead, Goeppert became interested in physics, and chose to pursue a Ph. D, in her 1930 doctoral thesis she worked out the theory of possible two-photon absorption by atoms. Eugene Wigner later described the thesis as a masterpiece of clarity, to honor her fundamental contribution to this area, the unit for the two-photon absorption cross section is named the Goeppert-Mayer unit. One GM is 10−50 cm4 s photon−1 and her examiners were three future Nobel prize winners, Max Born, James Franck and Adolf Otto Reinhold Windaus. On January 19,1930, Goeppert married Joseph Edward Mayer, the two had met when Mayer had boarded with the Goeppert family. The couple moved to Mayers home country of the United States and they had two children, Maria Ann and Peter Conrad

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

Peace
–
Peace is a lack of conflict and freedom from fear of violence between heterogeneous social groups. Commonly understood as the absence of hostility, peace often involves compromise, Peace can be defined in a positive direction and in a negative sense. Positively, peace is a state of tranquility and stillness, however, in a negative sense, the term peace originates most recently from the Anglo-French pes, and the Old French pais, meaning peace, reconciliation, silence, agreement. But, Pes itself comes from the Latin pax, meaning peace, compact, agreement, treaty of peace, tranquility, absence of hostility, harmony. At a personal level, peaceful behaviors are kind, considerate, respectful, just, and tolerant of others beliefs and behaviors — tending to manifest goodwill. This latter understanding of peace can also pertain to an individuals introspective sense or concept of her/himself, as in being at peace in ones own mind, as found in European references from c.1200. In many languages, the word for peace is used as a greeting or a farewell, for example the Hawaiian word aloha. In English the word peace is used as a farewell, especially for the dead. Religious beliefs often seek to identify and address the problems of human life. Among pagan faiths, worship of personified Peace was organized in antiquity under the name Eirene in Greek-speaking areas and as Pax in Latin-speaking ones and her idols depicted a full-grown woman, usually with a horn of plenty and scepter and sometimes with a torch or olive leaves. Christians, who believe Jesus of Nazareth to be the Jewish Messiah called Christ, numerous pontifical documents on the Holy Rosary document a continuity of views of the Popes to have confidence in the Holy Rosary as a means to foster peace. Islam derived from the root word salam which literally means peace, muslims are called followers of Islam. Quran clearly stated Those who have believed and whose hearts are assured by the remembrance of Allah. Unquestionably, by the remembrance of Allah, hearts are assured and stated O you who have believed, and when you are told, Arise, then arise, Allah will raise those who have believed among you and those who were given knowledge, by degrees. And Allah is Acquainted with what you do, buddhists believe that peace can be attained once all suffering ends. They regard all suffering as stemming from cravings, aversions, or delusions, to eliminate such suffering and achieve personal peace, followers in the path of the Buddha adhere to a set of teachings called the Four Noble Truths — a central tenet in Buddhist philosophy. Hindu texts contain the following passages, May there be peace in the heavens, peace in the atmosphere, let there be coolness in the water, healing in the herbs and peace radiating from the trees. Let there be harmony in the planets and in the stars, may everything in the universe be at peace

Medicine
–
Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. The word medicine is derived from Latin medicus, meaning a physician, Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Medicine has existed for thousands of years, during most of which it was an art frequently having connections to the religious and philosophical beliefs of local culture. For example, a man would apply herbs and say prayers for healing, or an ancient philosopher. In recent centuries, since the advent of modern science, most medicine has become a combination of art, while stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science. Prescientific forms of medicine are now known as medicine and folk medicine. They remain commonly used with or instead of medicine and are thus called alternative medicine. For example, evidence on the effectiveness of acupuncture is variable and inconsistent for any condition, in contrast, treatments outside the bounds of safety and efficacy are termed quackery. Medical availability and clinical practice varies across the world due to differences in culture. In modern clinical practice, physicians personally assess patients in order to diagnose, treat, the doctor-patient relationship typically begins an interaction with an examination of the patients medical history and medical record, followed by a medical interview and a physical examination. Basic diagnostic medical devices are typically used, after examination for signs and interviewing for symptoms, the doctor may order medical tests, take a biopsy, or prescribe pharmaceutical drugs or other therapies. Differential diagnosis methods help to rule out conditions based on the information provided, during the encounter, properly informing the patient of all relevant facts is an important part of the relationship and the development of trust. The medical encounter is then documented in the record, which is a legal document in many jurisdictions. Follow-ups may be shorter but follow the general procedure. The diagnosis and treatment may take only a few minutes or a few weeks depending upon the complexity of the issue, the components of the medical interview and encounter are, Chief complaint, the reason for the current medical visit. They are in the patients own words and are recorded along with the duration of each one, also called chief concern or presenting complaint. History of present illness, the order of events of symptoms. Distinguishable from history of illness, often called past medical history
