Albert Einstein was a famous mathematician. When he was a boy, he was an odd man out. But when was he an adult, boy was he smart. Yet, he counted on his fingers. He had a little sister that drove him CRAZY! One time, he had a temper tantrum that sent the baby sitter out of the house forever. And now, he will be known forever and always. He also knew about square roots like it was his brother. He LOVED math and that was that. My math teacher (Mrs. White) thinks he was really cool! I would like to learn some of the math he did. It would have been cool to be Albert Einstein. When he was a baby he had a fat head and he was chubby. But now Albert Einstein does not mean fat baby or big head. It means smart, smart man. He was the most important physicist of the 1990"s and one of the most famous scientists of all time. Some of his fame came from strange idea's that were later proved true. He was theoretical. When Einstein used his theory to calculate the precession of Mercury's orbit, the result agreed exactly with the observed motion. In the complex mathematics of relativity, time and space are not absolutely separate. The principle of equivalence states that the effects of gravity are equivalent to the effects of acceleration. To understand this principle, suppose you were in a rocket so far from any planet, star, or other celestial object that the ship experienced virtually no gravitation. Imagine that the ship was moving forward, but not accelerating_
