He decided to calculate sunrise and sunset. Then went through Kepler's calculations of the elliptical orbit of the earth in Excel, told me that perihelion is at January the third. We are retired and he enjoys going back through his calculus and math, now that he's old enough to really understand it.
Pretty amazing stuff.
Omar Khayyam came up with a calendar that is more accurate than the one we use and he lived around 1000 A.D.
Great movie: THE KEEPER:THE LEGEND OF OMAR KHAYYAM, 2005, with Vanessa Redgrave.
