Atomism or social atomism is a sociological theory arising from the scientific notion atomic theory, coined by the ancient Greek philosopher Democritus and the Roman philosopher Lucretius. In the scientific rendering of the word, atomism refers to the notion that all matter in the universe is composed of basic indivisible components, or atoms.
He described atomic theory as a 'Thoroughly materialistic bit of joiners work'. [77] English chemist Alexander Williamson used his Presidential Address to the London Chemical Society in 1869 [78] to defend the atomic theory against its critics and doubters. This in turn led to further meetings at which the positivists again attacked the ...
The law of multiple proportions is one of the basic laws of stoichiometry used to establish the atomic theory. Despite the importance of the work as the first view of atoms as physically real entities and the introduction of a system of chemical symbols, New System of Chemical Philosophy devoted almost as much space to the caloric theory as to ...
Atomic theory is one of the most important scientific developments in history, crucial to all the physical sciences. At the start of The Feynman Lectures on Physics , physicist and Nobel laureate Richard Feynman offers the atomic hypothesis as the single most prolific scientific concept.
1982 – The documentary film The Atomic Cafe, detailing society's attitudes toward the atomic bomb in the early Atomic Age, debuted to widespread acclaim. 1982 – Jonathan Schell's book Fate of the Earth, about the consequences of nuclear war, is published. The book "forces even the most reluctant person to confront the unthinkable: the ...
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.

But this ancient idea was based in philosophical reasoning rather than scientific reasoning. Modern atomic theory is not based on these old concepts. [2] [3] In the early 19th century, the scientist John Dalton found evidence that matter really is composed of discrete units, and so applied the word atom to those units. [4]
