Stone age to modern age

Events

Stone age

8000 B.C - 1000 B.C

-Used stones for tools
-found how to make, use and control fire
- lunation of glass and ceramic materials

Iron age

1200 B.C - 500 B.C

-found gold and copper
-extracted rocks
-investigated
-preserved mummies

-

Modern Age

1500 A.C - Present

-interests in the nature of matter
- 1660's Robert Boyle experimented with behavioural gases
-1770s french scientists Antoine Laurent Lavoisier studied chemical interactions.
-Late 1880s Antoine developed a system for naming chemicals
-1808 scientist John Dalton used the observations from his experiments to develop his own theory of the composition of matter.
-1897 Thomson proposed what is called the "raisin bun model" of the atom
-1904 the Japanese physicist Hantaro Nagaoka refined the model of the atom further.
-Rutherford won a nobel prize in 1808 for his work in radioactivity which he carried out at McGill University in Montreal from 1898 to 1907
-Danish researcher Niels Bohr who, working with Rutherford, suggested that electrons do not orbit randomly in an atom
-Bohr won the nobel prize in physics in 1922
Today most people still use the Bohr model to describe the particles that make up the atom.
