By john Dalton in 1808
The idea that led to the atomic theory of matter, was John Dalton.
There was no concrete evidence that led Dalton to propose his atomic theory. He proposed this theory based on logical explanations about the behavior of elements, gases or materials.
his observations led him to believe that gases are made of individual particles are very similar to the idia of the atom proposedby democritus
Gold foil experiment
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
He developed the theory of general and special relativity (E=mc2) which led to Robert Oppenheimer and his team creating the atomic bomb. The project was known as the Manhattan Project
Dalton's interest was sparked in atoms because he wanted to know why elements combine in specific proportions to form compounds. He was a pioneer in the development of modern atomic theory.
The idea was they believed that protoplasm was the same in all cells.
what led to the idea of usingpostage stamps
Besides discovering the photoelectric effect, Einstein developed the Theory of Special Relativity and the Theory of General Relativity, which are the basis for quantum theory and particle theory, and the formula E=Mc2 that indirectly led to the atomic bomb, nuclear power, and much of the current theory about the structure of the universe. Other than that, not much.
James Hanslow
he made a mistake in assuming that the simplest compound of two elements must be binary, formed from atoms of each element in a 1:1 ratio, and his system of atomic weights was not very accurate - he gave oxygen an atomic number of seven instead of eight. Despite these errors, Dalton's theory provided a logical explanation of concepts, and led the way into new fields of experimentation.
