John Dalton " Pool Ball Model "

John Dalton was a meteorologist, physicist, and English chemist in the 1700's - 1800's.  He was born on September 6, 1766 and was born colour blind.  He is mainly known for his modern atomic theory and his research towards colour blindness.   Dalton started out to run a Quaker school with his older brother, until 1793, he became a natural philosophy teacher at a college all because of John Gough.  In 1800 he resigned because of money issues, and soon became a tutor for another college. He started to work with different types of gases, which led him to the study of atoms.  He had five main points in his theory: 1st- the atoms of an element are different from those of another element. 2nd- all atoms of a given element are identical. 3rd- atoms with one element can combine with atoms with other elements to form chemical compounds. 4th- a chemical reaction only changes the way atoms are grouped in. 5th- elements are made up of atoms.

History- Thales

Thales was a pre-Socratic Greek philosopher from Miletus. It is said that he is one of the first Greek philosophers ever. He was trying to discover an explanation of the existence of the world without using mythology. Many other philosophers looked up to him and he later got the nickname of the " Father of Science ". He brought many new ideas to the scientific revolution because he did not believe in mythology. Thales was also called one of the first mathmaticians. He was the first one to use the deductive reasoning that applied to geometry, which led to Thale's Theorem.
