Planck's Constant -> 6.626 x 10^34
Also the idea of Quanta's, further researched by Einstien. :D
Atomic Theory
I don't know of atomic theory, but he came up with the idea that light energy acted like packetts of energy that he called photons. Thru some theoretical calculations he came up with Plank's constant that deals with the energy of different wavelengths of light.
Two related questions (completed with answers) should be followed.Cf 'Related questions' in the link below this answer.
Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
Mendel
Charles Darwin was a naturalist. His major contribution to science was the Theory of Evolution.
Aristotle did not believe in the Atomic Theory. He believed that everything was made up of only 4 elements fire, water, air, and earth. This theory was proven incorrect as is evidenced by the periodic table of elements. In short the answer to this question is, none.
They contributed the atomic bomb which had a major impact on the citizens of Hiroshima and Nagasaki.
One scientist who did not make a major contribution to cell theory was Lamarck. While Lamarck made significant contributions to evolution with his theory of inheritance of acquired characteristics, his work did not significantly impact the development of cell theory.
