Introduces the first atomic theory

WebDalton’s experiments with gases led to some of the earliest measurements of atomic masses and a concept of atomic structure and reactivity. Dalton’s atomic theory contained the following ideas: All atoms of a given element are identical. The atoms of different elements vary in mass and size. Atoms are indestructible.

Atomic theory is the scientific theory that matter is composed of particles called atoms. Atomic theory traces its origins to an ancient philosophical tradition known as atomism. According to this idea, if one were to take a lump of matter and cut it into ever smaller pieces, one would eventually reach a point where the pieces could not be further cut into anything smaller. Ancient Greek philosophers called these hypothetical ultimate particles of matter atomos, a word which mean… WebIn December of 1959, Richard Feynman gave a talk called “There’s Plenty of Room at the Bottom” at an annual meeting of the American Physical Society at Caltech.
