Imagine: You are a clever ancient Egyptian. It is almost 4,000 years before the magnetic compass will be invented, and the North Star isn't "north" yet. Pharoah commands that you use a simple method to orient his pyramid so that its sides are precisely aligned with the compass directions. But how? Ah, ha! You are holding your ankh staff and there are a few rocks at your feet. You think you have everything you need! So simple! Why hasn't anyone thought of this before?!       You will follow the ankh's shaddow through many days - before and after, and especially on the first day of Spring or Fall (the equinoxes). What could be simpler?! Back to the present - would this work in Australia? Or on Mars? Be sure to see: www.science-projects.com/Pyramid.htm
