History of Chem (by:Mandy)

drop the math, and lets learn a bit about the history of chemistry.
here are some of the important historical chemists:

Aristotle believed matter was made of different combinations of earth, air, fire, and water Lavoisier, A.L. (1743-1794)Discovered nitrogen; studied acids and described composition of many organic compounds.

Dalton, John (1766-1844)He proposed atomic theory, stated law of partial pressure of gases. His ideas led to laws of multiple proportions, constant composition and conservation of mass.

Thomson, Sir J.J. (1856-1940)Research on cathode rays resulted in proof of existence of electrons. Won the Nobel Prize in 1906

Rutherford, Ernest (1871-1937): Discovered that the atoms of the heavier elements, which had been thought to be irreversible, actually decay into various forms of radiation. Rutherford was the first to establish the theory of the nuclear atom and discovered rays: alpha, beta, and gamma. He also revealed the half-life of radioactive elements and applied this to studies of age determination of rocks by measuring the decay period of radium to lead-206. Have fun!
