                               PHYSICS TIMELINE
                              *******************
300BC--640 AD   Astronomers,philosophers, mathematicians and other scientists come to the library of Alexandria in Egypt.
1543 AD         Copernicus proposes the heliocentric theory---that the sun is at the centre of the solar system.
1609 AD         Galileo conducts his famous experiments on the velocities of falling objects.He also confirms the heliocentric theory.
