<p>Caltech students have long been known for their quirky sense of humor and creative pranks and for finding unusual ways to have fun. What is something that you find fun or humorous?</p>
<p>I wonder, how did you answer this question. I want to listen something funny, plz write your answers</p>
<p>Mine was last year at the state math meet a couple of my friends and I made paper airplanes and went to the top of the bleachers of the auditorium the meet was in and I threw one over a basketball court sized area covered with people. Watching people gawking at the lone airplane over their heads was funny. It did fly a long way:)</p>
<p>I just wrote my two favorite math jokes: The first takes place
in a world where functions, operators and constants walk: Functions e^x and 17 are walking along when they spot
an Operator: the Evil Derivative. "Oh no! I must hide!" screams 17, knowing that a meeting with the derivative
meant a constant's demise. The exponential function, however, expects no danger from the Derivative. It walks
right up and introduces itself, saying, "Hi, I'm e^x!". The Derivative replies: "Hi, I'm d/dy!"
"Proof" that every natural number is "cool": First, define "cool" and
"uncool" (not cool) to be mutually exclusive properties. Suppose there were at least one "uncool" natural number.
Then we could consider the nonempty set of uncool natural numbers. In particular, this set has a smallest
element, the smallest uncool number. But to be the smallest uncool number is definitely cool, making the smallest
uncool number both cool and uncool! This leads to a contradiction, as a number cannot be both cool and uncool.
We must conclude that our assumption that a nonempty set of uncool numbers exists is false. Thus every natural
number is cool.</p>
