Creation of the Telescope Lens
In this year Johannes Kepler helped Galileo create the telescope by creating the lens.The lens is a very important part of the telescope.When light passes through the objective lens,it is refracted.Then the light and the focal plane get at a certain angle.That is why we can see so far with a telescope.

isaac newton and the three laws of motion
Isaac Newton discoverd the three laws of motion in 1687! The first law is an object at rest will stay at rest and an object in motion will stay in motion. The second law states that the more force an object has the more it accelerates. The third law is there is an equal and opposite reaction to every action. JGM
