Back to school jokes for everyone

Theorem: Every positive integer is interesting. 

Proof: By contradiction, assume that there exists an uninteresting positive integer. Then there must be a smallest uninteresting positive integer. But that's pretty interesting! Therefore a contradiction!

Q: How many mathematicians does it take to screw in a light bulb?

A1: None. It's left to the reader as an exercise.

A2: None. A mathematician can't screw in a light bulb, but he can easily prove the work can be done. 

A3: One. He gives it to four programmers, thereby reducing the problem to the already solved

A4: The answer is intuitively obvious

Top ln(e^10) reasons why e is better than pi:
10) e is easier to spell than pi.
9) pi ~= 3.14 while e ~=2.718281828459045...
8) The character for e can be found on a keyboard, but pi sure can't.
7) Everybody fights for their piece of the pie.
6) ln(pi) is a really nasty number, but ln(e) = 1.
5) e is used in calculus while pi is used in baby geometry.
4) 'e' is the most commonly picked vowel in Wheel of Fortune.
3) e stands for Euler's Number, pi doesn't stand for squat.
2) You don't need to know Greek to be able to use e.
1) You can't confuse e with a food product.

Buffon's Needle and solving crimes

 There is a professor of mathematics working for FBI as a crime analyst in the NUMB3RS show. In an episode he uses a math theory to narrow a number of relevant court cases to only two. 

Next, the mathematician restricts his focus on only one case and states that Pi points to that case. Could Pi, the ratio of a circle's circumference and its diameter, help the crime investigation? 

Yes. Pi is also important in the field of probability. 

“Buffon's Needle is one of the oldest problems in the field of geometrical probability. It was first stated in 1777. It involves dropping a needle on a lined sheet of paper and determining the probability of the needle crossing one of the lines on the page. The remarkable result is that the probability is directly related to the value of pi.”
