Was a Canadian astronomer.He worked as a machinist, and was offered a job as a mechanician at the Department of Physics at the University of Toronto, constructing apparatuses and assisting with demonstrations during lectures. He found this so interesting that at the age of 30 he enrolled as an undergraduate in mathematics and physics. He stayed at the university until 1903, doing research on color photography.His formal astronomical career did not start until 1903, when he was appointed to the staff at Dominion Observatory in Ottawa. His achievements are all the more remarkable for this very late start.

Was an American botanist.Torrey was born in New York. When he was 15 or 16 years of age his father received a prison appointment at Greenwich, and there he made the acquaintance of Amos Eaton, a pioneer of natural history studies in America. He thus learned the elements of botany, as well as something of mineralogy and chemistry. In 1815 he began the study of medicine, qualifying in 1818. In the following year he issued his Catalogue of Plants growing spontaneously within Thirty Miles of the City of New York, and in 1824 he issued the only volume of his Flora of the Northern and Middle States.

Was an American ichthyologist.Nichols was curator of recent fishes at the American Museum of Natural History. In 1913 he founded Copeia which became the official journal of the American Society of Ichthyologists and Herpetologists in 1923. This society was established in 1913 too. In 1916 he was the first who described the long lost Bermuda Petrel which was rediscovered in 1906 by Louis Mowbray.

Was an English biologist and Roman Catholic priest.He did experiments with gravy and later tainted wheat that seemed to show that life was able to be generated from non-living material, or abiogenesis (spontaneous generation). Lazzaro Spallanzani repeated the experiments but this time covering the containers which contained the gravy and wheat (which Needham did not do), and the living organisms which appeared in Needham's original experiments did not appear. Needham argued that air was essential for the life, including those formed from spontaneous generation and that this air had been excluded in the experiments of Spallanzani, therefore destroying the 'vegetative force'.

Was a Canadian geophysicist and geologist who achieved worldwide acclaim for his contributions to the theory of plate tectonics.Plate tectonics is the idea that the rigid outer layers of the Earth (crust and part of the upper mantle), the lithosphere, are broken up into numerous pieces or "plates" that move independently over the weaker asthenosphere. Wilson maintained that the Hawaiian Islands were created as a tectonic plate, extending across much of the Pacific Ocean, shifted slowly in a northwesterly direction over a fixed hotspot, spawning a long series of volcanoes. He also conceived of the transform fault, a major plate boundary where two plates move past each other horizontally (e.g., the San Andreas Fault).

Was a Hungarian-born American mathematician who made major contributions to a vast range of fields including set theory, functional analysis, quantum mechanics, ergodic theory, continuous geometry, economics and game theory, computer science, numerical analysis, hydrodynamics (of explosions), and statistics, as well as many other mathematical fields. He is generally regarded as one of the foremost mathematicians of the 20th century. Most notably, von Neumann was a pioneer of the application of operator theory to quantum mechanics, a member of the Manhattan Project and the Institute for Advanced Study in Princeton (as one of the few originally appointed), and a key figure in the development of game theory and the concepts of cellular automata and the universal constructor. Along with Ede Teller (known as Edward) and Stanislaw Ulam, von Neumann worked out key steps in the nuclear physics involved in thermonuclear reactions and the hydrogen bomb.

He is famous for the 1869 Powell Geographic Expedition, a three-month river trip down the Green and Colorado rivers that included the first passage through the Grand Canyon.He studied at Illinois College, Wheaton College, and Oberlin College, acquiring a knowledge of Ancient Greek and Latin but never graduating. Powell had a deep interest in the natural sciences, with a restless nature. As a young man, he undertook a series of adventures through the Mississippi River valley. In 1855 he spent four months walking across Wisconsin. In 1856 he rowed the Mississippi from St. Anthony to the sea,

Was an English surgeon and botanical collector.White was born in Sussex (some sources state he was born in 1750)[1] and entered the Royal Navy on 26 June 1778 as third surgeon's mate[2]. He was promoted surgeon in 1780, and was the principal surgeon during the voyage of the First Fleet to Australia. In March 1787 White joined the First Fleet transports at Plymouth, where he found that the convicts had been living for some time on salt meat, a bad preparation for a long voyage. He succeeded in obtaining supplies of fresh meat and vegetables for them, and arranged that they should be allowed up on deck in relays to obtain fresh air. His sensible and humane treatment was probably the reason why the number of convict deaths during the voyage was not higher.[1] John White was a surgeon serving on the ship Charlotte during his voyage to Australia.

Was the 2nd Hollis Professor of Mathematics and Natural Philosophy in Harvard College. He was a distinguished mathematician, physicist and astronomer, born in Boston, Mass. His great-great-grandfather, also named John Winthrop, was founder of the Massachusetts Bay colony. He graduated in 1732 at Harvard, where, from 1738 until his death he was professor of mathematics and natural philosophy. Professor Winthrop was one of the foremost men of science in America in the eighteenth century, and his influence on the early advance of science in New England in particular was very great. Both Benjamin Franklin and Benjamin Thompson (Count Rumford) probably owed to him much of their early interest in scientific research.
