In his Twitter feed, Clifford Pickover (@Pickover) recently linked to this very good, and visual, presentation of Benford's Law:

...and here are a few other miscellaneous Pickover tweets I've jotted down over the last few months:

23 is the only prime number p such that p! is p digits long.

Aside from 17, humans will never find a prime that is the average of two consecutive Fibonacci numbers.

 19 is the only known prime of the form n^n - 8. The next prime of this form (if it exists) must be more than 34,000 digits.

Prince Rupert's cube and 1.06066 at Wikipedia:

Answer this question with "yes" or "no". Will your next word be "no"?
