Arthur Eddington was an English physicist, astronomer, and mathematician. He wrote numerous articles that explained Albert Einstein's theory of general relativity to the English-speaking world. He began his career in academics and eventually shifted to astronomy, becoming the chief assistant to the Astronomer Royal at the Royal Greenwich Observatory. He was a recipient of the Henry Draper Medal.
Alfred North Whitehead was a British mathematician and philosopher, best known for his collaboration with his student Bertrand Russell on Principal of Mathematics, a three-volume work on the foundations of mathematics. Also known for his pioneering works on process philosophy and metaphysics, he is credited with developing a comprehensive metaphysical system that differs from most Western philosophies.
11 Ronald Ross
Nobel Prize-winning British doctor Ronald Ross is best remembered for his pathbreaking work on malaria, which proved that the disease was caused by the Anopheles variant of mosquitoes. After his extensive research in India, he went back to London, where he was knighted. He also wrote poetry and songs.
One of the two pioneering female honorary members of the Royal Astronomical Society, Mary Somerville was a 19th-century polymath and science writer. Though she specialized in math and astronomy, she was also well-versed in botany and geology. The Connection of the Physical Sciences remains her most notable work.
14 Karl Pearson
One of the greatest statisticians of all time, Karl Pearson established the first university-level statistics department at UCL and also launched the statistics-oriented journal Biometrika. He was also well-versed in law and believed in eugenics. His The Grammar of Science later inspired Albert Einstein and other scientists.
Oliver Heaviside was an English mathematician and physicist. He invented a new technique for solving differential equations and independently developed vector calculus. He is also credited with rewriting Maxwell's equations in the form commonly used today. He formulated the telegrapher’s equations and invented the Heaviside step function as well. In 1922, he received the Faraday Medal.
16 John Venn
Sir George Stokes, 1st Baronet was an Anglo-Irish physicist and mathematician. He studied at Pembroke College, Cambridge, and spent his entire career at the University of Cambridge as the Lucasian Professor of Mathematics. As a physicist, he made key contributions to fluid mechanics and physical optics. He received the Royal Society's Copley Medal in 1893.
Alastair Denniston was a Scottish code breaker and hockey player. He was deputy head of the Government Code and Cypher School (GC&CS) from 1919 to 1942. As a member of the Scottish Olympic hockey team in 1908, he won a bronze medal. He worked as a code breaker during the war years. He taught French and Latin following his retirement.
William Henry Bragg was an English physicist, chemist, and mathematician. He is best known for sharing the 1915 Nobel Prize in Physics with his son Lawrence Bragg for their work in the analysis of crystal structure by means of X-rays. William Henry Bragg had an illustrious academic career and was elected president of the Royal Society in 1935.
20 George Green
With one year of formal schooling, George Green was entirely self-taught until the age of forty, when he entered Gonville and Caius College, Cambridge. By then, he had published his first book, propagating what are now known as Green’s theorem and Green’s functions. A fellow of the Cambridge Philosophical Society, he also established Green's identities, Green's law, and Green's matrix.
Born to legendary biologist Charles Darwin, George Darwin initially studied law and became a barrister. However, his interest in science made him deviate to astronomy. He believed the Moon was one part of the Earth. He later also taught at Cambridge and was made a Fellow of The Royal Society.
British physicist, meteorologist, mathematician, psychologist and pacifist Lewis Fry Richardson was the first to apply modern mathematical techniques of weather forecasting to predict weather accurately. He also pioneered the use of similar methods in studying reasons of wars and the way to stop them. He proposed the iterative method called modified Richardson iteration for solving a system of linear equations.
Francis Ysidro Edgeworth was an Anglo-Irish economist and statistician, known for his significant contributions to the methods of statistics. An autodidact in mathematics and economics, he imaginatively applied mathematics to the fields of economics and statistics, writing several books, including Mathematical Psychics, presenting new ideas on various topics like on the generalized utility function, the indifference curve etc. .
27 G. I. Taylor
G. I. Taylor was a British physicist and mathematician. He was a key figure in fluid dynamics and wave theory. He worked on the development of supersonic aircraft while serving on the Aeronautical Research Committee. Counted among the most notable scientists of the 20th century, he was the recipient of several prestigious awards, including the Franklin Medal.
30 James Jeans
James Jeans was an English physicist, astronomer, and mathematician who made great contributions to the areas of quantum theory, the theory of radiation, and stellar evolution. Along with Arthur Eddington, Jeans is a founder of British cosmology. He spent his academic career at Trinity College, Cambridge, and the Princeton University. He received the Royal Medal in 1919.
Hertha Ayrton was a British engineer, physicist, mathematician, and inventor. She is remembered for her work on electric arcs and ripple marks in sand and water, for which she was awarded the Hughes Medal by the Royal Society. As a woman in the 19th century, she had to face innumerable struggles in her career. She was also a passionate suffragist.
Born to a Scottish factor, mathematician Eric Temple Bell spent most of his life in the U.S. The Stanford alumnus contributed to the analytic number theory and also taught math at institutes such as Caltech. He also penned sci-fi novels such as The Time Stream as John Taine.
37 G. S. Carr
38 Horace Lamb
British astrophysicist and cosmologist Edward Arthur Milne was a brilliant student and a Cambridge scholar. Remembered for his work on kinematic relativity, he introduced the Milne model, too. He applied the Saha equation in his studies on the spectral lines of stars and also lectured on Christianity.
