Newton

S5, E10: Maestro explains that it only became possible for astronauts to move in space thanks to the brilliant discoveries and calculations of a certain Sir Isaac Newton. As a little boy, Isaac tended the sheep of his father. Even at that young age, his amazing talent for inventing became obvious. He developed several machines, invented water meters and constructed some elaborate kites. At his father’s farm, he developed his theory of light. One day, an apple falls from a tree right onto his head. That’s when he suddenly has an idea of the gravitation theory.
