After having sat dormant for more than two thousand years, atomic theory was finally brought into the modern age with the work of John Dalton.

Brief biography of John Dalton, scientist and weather pioneer who established the modern concept of atoms known as Dalton's Atomic Theory.

Following up on the work of John Dalton, Robert Brown and, later, Albert Einstein, would finally help to convince the world of the existence of atoms.

Atoms, of course, have existed since the beginning of time. Man's study of them, however, did not begin until considerably after that.

The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.

Much of the difficulty scientists had in discovering, and then proving the existence of, atoms, is their size. Something so small had never before been defined.

In order to understand many phenomena in the study of chemistry it is important to know how atoms are made up.

The earliest use of the guillotine as a method of execution took place in England, not France. The use of the Gibbet pre-dates the French guillotine by several centuries.

When Atomic Theory began to grow in popularity during the nineteenth century, it did so in part thanks to the mathematical work of Austrian Physicist Ludwig Boltzmann.

This is a hands-on, minds-on approach to providing students with a concrete model of the earth's atmosphere to visualize the gases that comprise the atmosphere.

New Zealander Ernest Rutherford made waves in the scientific community in the first couple decades of the twentieth century with his work on the atomic structure.

Several times over the last 500 years low sunspots numbers have coincided with much cooler global temperatures. Is there a connection or is it coincidence?

In 2008, no sunspots were observed on 266 of the year's 366 days (73%), a low surpassed only in 1913, which had 311 spotless days (85%).

In 1932, James Chadwick proved that the atomic nucleus contained a neutral particle which had been proposed more than a decade earlier by Ernest Rutherford.
