With King Tut going under the X-ray machine to determine the exact cause of his death over 3,000 years ago, it's time to remember your fifth grade civics class lessons as to who this guy actually was. National Geographic has put together a great Web site  documenting the opening of Tut's tomb in 1923. But if you want to see Tut and his treasures, you'll have to travel to Bonn, Germany. The traveling Tut exhibition  from the Egyptian Museum of Cairo will be stopping over in the city through May 1.
