Nicolas Chuquet was a 15th century French mathematician.
The exact dates of birth and death of this scientist are not known, nor are the places of birth. Chuquet received a Bachelor of Medicine degree from the University of Paris, went to Italy in the early 1470s, and around 1480 moved to Lyon, where he worked as a physician, mathematics teacher, and scribe. He is also known to have translated Latin works into French.
In 1484 he wrote his major algebraic work, the treatise Le Triparty en la Science des Nombres (The Science of Numbers in Three Parts), now considered one of the most original mathematical texts of the 15th century. At the time, arithmeticians lacked even the most basic notations for addition subtraction, multiplication, and division. Chuquet was one of the first to propose these symbols; he also introduced the names of large numbers into common use: billion, trillion, etc. In addition to general arithmetic and rules for calculating roots, the treatise contains a doctrine of equations and a collection of problems.
This treatise was published only in 1880, but the works of Nicolas Chuquet had a significant influence on the development of algebra, and they were consistently supplemented and expanded by scientists of the following generations.
Charles Robert Darwin was an English naturalist, geologist, and biologist, widely known for contributing to the understanding of evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.

Albert Einstein was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics. His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. 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", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius".
Michael Faraday was a British physicist and chemist, explorer and experimenter.
Faraday, because of his family's poverty, was unable to receive a formal education, but at the bookbinding shop in London where he worked, he read many books, including encyclopedias and textbooks on chemistry and physics. He persevered in self-education, attending hearings at the City Philosophical Society and later lectures by Sir Humphry Davy at the Royal Institution, who as a result took the able student on as an apprentice. In 1825 he replaced the seriously ill Davy in the management of the laboratory of the Royal Institution.
In 1833 Faraday was appointed to a research chair of chemistry created especially for him, where, among other achievements, the scientist liquefied various gases, including chlorine and carbon dioxide. His study of heating and lighting oils led to the discovery of benzene and other hydrocarbons, and he experimented extensively with various steel alloys and optical glasses. Faraday was an excellent experimentalist who presented his ideas in simple language. He is best known for his contributions to the understanding of electricity and electrochemistry. The concepts behind electromagnetic induction, diamagnetism, and electrolysis were some of his most important discoveries. His electromagnetic research formed the basis of the electromagnetic equations that James Clerk Maxwell developed in the 1850s and 1860s.
Between 1831 and 1855, Faraday read a series of 30 papers before the Royal Society, which were published in his three-volume Experimental Investigations in Electricity. His bibliography numbers some 500 printed articles. By 1844 he had been elected a member of some 70 scientific societies, including the St. Petersburg Academy of Sciences.
Levinus Lemnius (Dutch: Lieven Lemse, Lenneus, Lennius, Lemmens, Lemnii of Lemnes) was a Dutch physician, philosopher, botanist and writer.
He studied under the famous Swiss botanist and bibliographer Conrad Gesner at the University of Louvain and under the famous Flemish anatomist Andreas Vesalius at the University of Padua. Lemnius's book On the Habit and Constitution of the Body was translated by Thomas Newton, an Anglican clergyman who translated some of Lemnius's treatises into English, as well as other modern continental and classical works.
Lemnius is considered the first author to describe the plants mentioned in the Bible, in T. Newton's translation, Herbal for the Bible (1587). Levin Lemnius's most famous book is Occulta naturae miracula (1559), a book of mysteries that was reprinted many times over a period of four hundred years.

Farkas Bolyai, also known as Wolfgang Bolyai in Germany, was a Hungarian mathematician, mainly known for his work in geometry.
Henry DeWolf Smyth was an American scientist, nuclear physicist, and diplomat.
Smyth studied at Princeton and Cambridge Universities, taught in Princeton's physics department from 1924 to 1966, and chaired the department for many years. At first he investigated the ionization of gases, but from the mid-1930s he turned his attention to nuclear physics. During World War II, Smith was a member of the uranium section of the National Defense Research Committee. He also proposed electromagnetic techniques that were used to enrich the first samples of U-235 during the Manhattan Project. Smith worked as a consultant on this project from 1943 to 1945 and served as deputy director of the Metallurgical Laboratory at the University of Chicago.
In 1944, General Leslie Groves appointed Henry Smith to the Committee on Postwar Policy to propose a public policy for research and development of atomic energy after the war. He wrote the official public report on the bomb, which became known as the Smith Report and was widely distributed throughout the country.
After the war, Henry DeWolf Smith served as commissioner of the U.S. Atomic Energy Commission and as the U.S. representative to the International Atomic Energy Agency (IAEA). In 1953, he was President Eisenhower's chief advisor on Ike's "Atoms for Peace" speech and received the Atoms for Peace Award in 1968.
Francis Harry Compton Crick was a British molecular biologist, biophysicist and neuroscientist. He won the Nobel Prize in Physiology and Medicine in 1962.
During World War II he had to work on developments for the military, and in 1947 he turned to biology at the Strangeways Research Laboratory, University of Cambridge. In 1949 he moved to the University Medical Research Council at Cavendish Laboratories. Using X-ray diffraction studies of DNA by biophysicist Maurice Wilkins (1916-2004) and X-ray diffraction images taken by Rosalind Franklin, biophysicist James Watson and Crick were able to construct a molecular model consistent with the known physical and chemical properties of DNA.
This achievement became a cornerstone of genetics and was regarded as one of the most important discoveries of 20th century biology. In 1962, Francis Crick, along with James Watson and Maurice Wilkins, won the Nobel Prize in Physiology or Medicine for determining the molecular structure of deoxyribonucleic acid (DNA), the chemical ultimately responsible for the hereditary control of life functions.
From 1977 until the end of his life, Crick served as professor emeritus at the Salk Institute for Biological Studies in San Diego, California, where he conducted research on the neurological basis of consciousness. He also wrote several books. In 1991, Francis Crick received the Order of Merit.

Ronald Wilson Reagan was an American statesman and politician, the 40th President of the United States of America (1981-1989).
Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets move around the Sun in elliptical orbits.
Kepler created the three fundamental laws of planetary motion. He also did seminal work in optics and geometry, calculated the most accurate astronomical tables, and made many inventions and discoveries in physics on which further scientific discoveries by advanced scientists were based.
