It’s time for the answer to life, the universe, and everything in Carnival Form: Carnival of Mathematics #42 is up over at The Endeavour, a blog by John D. Cook. His blog has neat articles like how to convert files to .pdf and Jenga Math (weakening the hypothesis of a theorem without causing the whole thing to collapse). The Carnival has lots of neat articles on logic, computer science, and how the check-sum digit works on credit cards. So pull up a chair and Enjoy!
