Modern Atomic Theory - In view of new discoveries about atoms, Dalton's atomic theory was modified as given below: Atom is no longer indivisible as it has a complex structure of sub atomic particles (electrons, protons and neutrons). Atoms of the same element may posse..

In view of new discoveries about atoms, Dalton's atomic theory was modified as given below: Atom is no longer indivisible as it has a complex structure of sub atomic particles (electrons, protons and neutrons). Atoms of the same element may posses different relative masses (isotopes). Cer..

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 extremely well polished ..

Although Dalton's theory of the existence of atoms was published in 1808, there was no clear idea of what an atom might look like until the early part of the twentieth century. With the advent of electricity and phenomenon of spectrum, experimentation underwent a change and a flurry of r..

The theory put forth by Darwin and Wallace gained wide acceptance. However, in the light of modern evidences, it was slightly modified and called the neo-Darwinism. In neo-Darwinism, organic evolution is by natural selection of inherited characters. It utilises evidences from va..

The Atom - When scientists started exploring matter, they realised that matter can be divided into smaller and still smaller particles. What was the ultimate particle like? They discovered that the smallest particle of an element that maintains its chemical identity through all chemical and phys..

Evolution - Exploration of the planets by space probes has expanded our understanding of the solar system. Modern theories about the earth's origin explore how the earth fits into the solar system, the Milky Way galaxy, and the universe as a whole. Most scientists agree that the..

According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline substance in whi..

Introduction - We are already familiar with set theory and mathematical logic from earlier classes. It has already been seen that there is a similarity between the laws stated in set theory and the mathematical logic. The operations 'union', 'intersection' and 'complement' on se..
