Who mailed Indiana Jones' journal to the University of Chicago?

The real journal hopefully remains in the possession of movie character Indiana Jones. A remarkable, handmade copy, however, was mailed by mistake to Henry Walton Jones Jr. -- the given name of the globe-trotting antiquities hunter -- at the real university. The quality of the book and the school's efforts to track down "Jones" triggered an Internet sensation. The book was the handy work of an artist in Guam who produces detailed replicas of props. After it became separated from a larger package sent to a client, it was dutifully forwarded by a postal worker based on an address on the replica.

How big was Noah's Ark according to the Bible?

The ark was a whopping 427 feet long, 95 feet across and 75 feet high, according to Dutchman Johan Huibers, who has used the Bible's detailed description to build and launch a full-scale working replica of the legendary vessel. The modern ship was built to mirror the ancient version, which, the story says, was used to save Noah's family and two each of the world's animals from drowning in a great flood. It contains a huge space of stalls with stuffed and plastic animals, such as buffalo, zebra, gorillas, lions, tigers and bears. There also is a petting zoo with ponies, dogs, sheep and rabbits. The ship is moored in the city of Dordrecht, just south of Rotterdam.
