Michael Faraday FRS (22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.<br/><br/> Although Faraday received little formal education, he was one of the most influential scientists in history. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the basis for the concept of the electromagnetic field in physics. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology.<br/><br/> Faraday ultimately became the first and foremost Fullerian Professor of Chemistry at the Royal Institution of Great Britain, a lifetime position.

Halley's Comet or Comet Halley is a short-period comet visible from Earth every 75–76 years. Halley is the only short-period comet that is clearly visible to the naked eye from Earth, and the only naked-eye comet that might appear twice in a human lifetime. Halley last appeared in the inner Solar System in 1986 and will next appear in mid-2061.
Galileo Galilei (15 Feb. 1564—8 Jan. 1642) was an Italian physicist, mathematician, philosopher and astronomer who played a pivotal role in establishing modern science at a time when contradiction of religion was considered heresy. It was as an astronomer that he was most controversial. Galileo developed telescopes that confirmed the phases of Venus, and the discovery of the four largest satellites of Jupiter (named the Galilean moons in his honour), as well as sunspots.<br/><br/> In 1610, while a majority of philosophers and astronomers still subscribed to the geocentric opinion that the Earth was the centre of the universe, Galileo came out in support of Copernicus' heliocentric view that the Sun was at the center of the solar system.<br/><br/> Galileo's opinions were met with outrage and bitter opposition, and he was denounced to the Roman Inquisition. In February 1616, although he had been cleared of any offence, the Catholic Church nevertheless condemned heliocentrism as 'false and contrary to [Christian] Scripture' and forced Galileo to renounce his scientific conclusions.<br/><br/> However, in 1632, Galileo published 'Dialogue Concerning the Two Chief World Systems', in which he again defended heliocentrism. He was tried by the Inquisition, found 'vehemently suspect of heresy', forced to recant, and spent the rest of his life under house arrest.

Leonhard Euler (15 April 1707 – 18 September 1783) was a Swiss mathematician, physicist, astronomer, logician and engineer who made important and influential discoveries in many branches of mathematics like infinitesimal calculus and graph theory, while also making pioneering contributions to several branches such as topology and analytic number theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy, and music theory.<br/><br/> Euler was one of the most eminent mathematicians of the 18th century, and is held to be one of the greatest in history. He is also widely considered to be the most prolific mathematician of all time. His collected works fill 60 to 80 quarto volumes, more than anybody in the field. He spent most of his adult life in St. Petersburg, Russia, and in Berlin, then the capital of Prussia.
Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist and philosopher of science. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). He is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed 'the world's most famous equation'). He received the 1921 Nobel Prize in Physics 'for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect'. The latter was pivotal in establishing quantum theory.<br/><br/> Einstein was visiting the United States when Adolf Hitler came to power in 1933 and, being Jewish, did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the USA, becoming an American citizen in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential development of 'extremely powerful bombs of a new type' and recommending that the U.S. begin similar research. This eventually led to what would become the Manhattan Project.<br/><br/> Einstein published more than 300 scientific papers along with over 150 non-scientific works. His intellectual achievements and originality have made the word 'Einstein' synonymous with genius.
Mileva Maric (December 19, 1875 – August 4, 1948) was a Serbian physicist. She was the only woman among Albert Einstein's fellow students at the Zurich Polytechnic. They developed a relationship and had a daughter before their marriage, Lieserl, who either died young or was given up for adoption. After their marriage in 1903, they had two sons, Hans Albert and Eduard.<br/><br/> They separated in 1914, with Maric taking the boys and returning to Zurich from Berlin. They divorced in 1919; that year Einstein married again. When he received the Nobel Prize in 1921, he transferred the money to Maric, chiefly to support their sons.
James Ferguson (25 April 1710 – 17 November 1776) was a Scottish astronomer, instrument and globe maker.<br/><br/> It is as the inventor and improver of astronomical and other scientific apparatus, and as a striking instance of self-education, that he claims a place among the most remarkable men of science of his country.

Abu ʿAlī al-Husayn ibn ʿAbd Allah ibn Sīna (c. 980, Afshana near Bukhara – 1037, Hamadan, Iran), commonly known as Ibn Sīna or by his Latinized name Avicenna, was a Persian polymath, who wrote almost 450 treatises on a wide range of subjects, of which around 240 have survived. In particular, 150 of his surviving treatises concentrate on philosophy and 40 of them concentrate on medicine.<br/><br/> His most famous works are <i>The Book of Healing</i>, a vast philosophical and scientific encyclopaedia, and <i>The Canon of Medicine</i>, which was a standard medical text at many medieval universities. <i>The Canon of Medicine</i> was used as a text-book in the universities of Montpellier and Leuven as late as 1650. Ibn Sīna's <i>Canon of Medicine</i> provides a complete system of medicine according to the principles of Galen and Hippocrates.<br/><br/> His corpus also includes writing on philosophy, astronomy, alchemy, geology, psychology, Islamic theology, logic, mathematics, physics, as well as poetry. He is regarded as the most famous and influential polymath of the Islamic Golden Age.

Avempace (c. 1085 – 1138) is the Latinate form of Ibn Bajja, full name Abu Bakr Muḥammad Ibn Yahya ibn as-Saiigh at-Tujibi Ibn Bajja al-Tujibi, a medieval Andalusian Arab. His writings include works regarding astronomy, physics, and music, as well as philosophy, medicine, botany, and poetry.<br/><br/> He was the author of the <i>Kitab al-Nabat</i> ('The Book of Plants'), a popular work on botany, which defined the sex of plants. His philosophic ideas had a clear effect on Ibn Rushd (Averroes) and Albertus Magnus. Most of his writings and books were not completed (or well-organized) because of his early death. He had a vast knowledge of medicine, mathematics and astronomy. His main contribution to Islamic philosophy is his idea on soul phenomenology, which was never completed.

Teller immigrated to the United States in the 1930s, and was an early member of the Manhattan Project charged with developing the first atomic bombs. During this time he made a serious push to develop the first fusion-based weapons as well, but these were deferred until after World War II.<br/><br/> After his controversial testimony in the security clearance hearing of his former Los Alamos colleague J. Robert Oppenheimer, Teller was ostracized by much of the scientific community. He continued to find support from the U.S. government and military research establishment, particularly for his advocacy for nuclear energy development, a strong nuclear arsenal, and a vigorous nuclear testing program.<br/><br/> He was a co-founder of Lawrence Livermore National Laboratory (LLNL), and was both its director and associate director for many years.

Abū ʿAlī al-Ḥasan ibn al-Ḥasan ibn al-Haytham (Arabic: أبو علي، الحسن بن الحسن بن الهيثم, Persian: ابن هیثم, Latinized: Alhacen or Alhazen, 965 in Basra – c. 1040 in Cairo) was a Muslim, Persian or Arab scientist and polymath. He is frequently referred to as Ibn al-Haytham, and sometimes as al-Basri (Arabic: البصري), after his birthplace in the city of Basra.<br/><br/> Alhazen made significant contributions to the principles of optics, as well as to physics, astronomy, mathematics, ophthalmology, philosophy, visual perception, and to the scientific method. He was also nicknamed Ptolemaeus Secundus ('Ptolemy the Second') or simply 'The Physicist' in medieval Europe. Alhazen wrote insightful commentaries on works by Aristotle, Ptolemy, and the Greek mathematician Euclid.<br/><br/> Born circa 965, in Basra, Iraq, he lived mainly in Cairo, Egypt, dying there at age 76. Over-confident about practical application of his mathematical knowledge, he assumed that he could regulate the floods of the Nile. After being ordered by Al-Hakim bi-Amr Allah, the sixth ruler of the Fatimid caliphate, to carry out this operation, he quickly perceived the impossibility of what he was attempting to do, and retired from engineering.<br/><br/> Fearing for his life, he feigned madness and was placed under house arrest, during and after which he devoted himself to his scientific work until his death.

Galileo Galilei (15 Feb. 1564—8 Jan. 1642) was an Italian physicist, mathematician, philosopher and astronomer who played a pivotal role in establishing modern science at a time when contradiction of religion was considered heresy. It was as an astronomer that he was most controversial. Galileo developed telescopes that confirmed the phases of Venus, and the discovery of the four largest satellites of Jupiter (named the Galilean moons in his honour), as well as sunspots.<br/><br/> In 1610, while a majority of philosophers and astronomers still subscribed to the geocentric opinion that the Earth was the centre of the universe, Galileo came out in support of Copernicus' heliocentric view that the Sun was at the center of the solar system.<br/><br/> Galileo's opinions were met with outrage and bitter opposition, and he was denounced to the Roman Inquisition. In February 1616, although he had been cleared of any offence, the Catholic Church nevertheless condemned heliocentrism as 'false and contrary to [Christian] Scripture' and forced Galileo to renounce his scientific conclusions.<br/><br/> However, in 1632, Galileo published 'Dialogue Concerning the Two Chief World Systems', in which he again defended heliocentrism. He was tried by the Inquisition, found 'vehemently suspect of heresy', forced to recant, and spent the rest of his life under house arrest.

Julius Robert Oppenheimer(April 22, 1904 – February 18, 1967) was an American theoretical physicist and professor of physics at the University of California, Berkeley. He is among the persons who are often called the 'father of the atomic bomb' for their role in the Manhattan Project, the World War II project that developed the first nuclear weapons. The first atomic bomb was detonated on July 16, 1945, in the Trinity test in New Mexico; Oppenheimer remarked later that it brought to mind words from the Bhagavad Gita: 'Now I am become Death, the destroyer of worlds'.<br/><br/> After the war he became a chief advisor to the newly created United States Atomic Energy Commission and used that position to lobby for international control of nuclear power to avert nuclear proliferation and an arms race with the Soviet Union. After provoking the ire of many politicians with his outspoken opinions during the Second Red Scare, he had his security clearance revoked in a much-publicized hearing in 1954, and was effectively stripped of his direct political influence; he continued to lecture, write and work in physics. Nine years later President John F. Kennedy awarded (and Lyndon B. Johnson presented) him with the Enrico Fermi Award as a gesture of political rehabilitation.
