Even though the laws of friction have been understood since a long time, some properties were understood properly, only after the discovery of atoms and molecules. No matter how well polished two surfaces are, at the atomic level they are never plane. Sometimes, when these extr..

Bohr's Theory of Hydrogen Atom - Niels Bohr suggested that the problem about hydrogen spectrum can be solved if we can make some assumptions. According to classical theory, the frequency of the electromagnetic waves emitted by a revolving electron is equal to the frequ..

John Dalton, a British school teacher, published his theory about atoms in the year 1808. His findings were based on experiments and also from laws of chemical combinatio..

John Dalton provided a simple theory of matter to provide theoretical justification to the laws of chemical combinations in 1805. The basic postulates of the theory are: All substances are made up of tiny, indivisible particles called atoms. Atoms of the same..
