Math Jokes
"An infinite number of mathematicians walk into a bar. The first orders a beer. The second orders half a beer. The third orders a third of a beer. The bartender bellows "Get out of here! Are you trying to ruin me?"
"To a topologist, a doughnut is the same as a coffee cup."
"Why did the chicken cross the Mobius strip? To get to the same side!"
e^x was walking down the street one day and met a polynomial running in the opposite direction.
"Wait, why are you running?" asked e^x. The polynomial said:
"There's a differential operator over there! It could differentiate me and turn me into zero!" And the polynomial continued running in fright.
"Ha ha," e^x said to himself. "I'm e^x! Let them differentiate me as many times as they want, it makes no difference to me!" So e^x walked on and reached the
differential operator. He confidently introduced himself: "Hi, I'm e^x!" The reply:
"Hi, I'm ∂/∂y!"
And that was when e^x learned the true meaning of fear: all his life, he'd believed himself to be invulnerable to differentiation and integration. It was the only thing rock-steady e^x had ever known: all his life, everyone around him had told him that he could never change - at least not at the hands of the differential operator.
