Isaac Newton was a British astronomer,
mathematician, inventor, philosopher and physicist. He was born in 1643 and was
very curious as a boy. His hobbies included drawing the construction of wooden
objects. His earlier inventions were a sundial and a windmill. CHILDHOOD
Newton is most famous for his ideas about
motion, forces, gravity and light. According to legend, Newton started working
on the gravitational theory after he saw and apple fall from a tree. He argued
that gravity explains why objects fall to the ground, why planets orbit the sun
and why ocean tides occur. FORCES
Newton also investigated the properties of
light. He shone a white light through a prism ( a transparent piece of glass
with a triangular cross section) and demonstrated that white light refracts
into seven separate colours. He also studied the speed of sound and built the
first reflecting telescope.
