Words of the Day:Haram (singular) and ahram (plural) mean "pyramid(s)" in Egyptian Arabic.
Tech Fact of the Day: The ancient Egyptians were excellent mathematicians. Among their other achievements, they figured out how to construct right angles by using triangles whose sides measured 3, 4, and 5, or 5, 12, and 13 units. Without right angles they would have found it very hard to build the pyramids!
