If there was a Hall of Fame for scientists, physicist Isaac Newton (1642-1727) would’ve been the charter member. He was like Elvis Presley and Chuck Berry were to rock and roll, like Babe Ruth to baseball. The theory of gravity and the three laws of motion were his gifts to the world. He made major contributions to mathematics and optics, and was a central figure in defining modern science. There’s a legend that he invented the cat door, inspired by his pet felines. Whether or not it’s true, it’s an excellent metaphor for this horoscope. It’s a great time to apply your finest talents and highest intelligence to dream up small, mundane but practical innovations.
