The Charter School is named Kidinnu Academy in honor of Kidinnu, a Chaldean astronomer and mathematician.
Kidinnu lived in the late 4th or early 3rd century BCE. He was an astronomer and mathematician who is believed to be responsible for a Babylonian theory that described the speed of the moon’s and sun’s motions and lunar phases and eclipses.
Kidinnu applied mathematical rules to the variations in the speed of the Sun and the Moon and worked out predictions of lunar phenomena.
Kidinnu is also attributed with discoveries relating to the motion of Mercury and the relationship between two different lunar periods.
