I found something interesting on Bill O'Reilly's website today. If you notice on this quiz, question 4 states that the 'c' in E = mc^2 represents the speed of sound. I'm sure Mr. O'Reilly did not create this quiz, that would be giving the gentleman too much credit. That aside, are we to take this gross lapse in basic knowledge of relativistic phyics and/or proof reading as a prelude to an imminent war on physics as well? Probably not, but it's difficult to put anything past Mr. O'Reilly.
