Beer and Calculus Don’t Mix — Don’t Drink and Derive!

After Franklin Delano Roosevelt signed the Cullen-Harrison Act to end prohibition, sales of beer in the U.S. became legal on April 7, 1933. (Not a moment too soon, I might add. My father was born on April 12, 1933, and he surely gave my grandmother plenty of reasons to imbibe!) Consequently, April 7 is now known as National Beer Day, and April 6 is unofficially New Beer’s Eve.

A definite integral walks into a bar and orders five pints of Guinness. The bartender pours them, and the definite integral finishes them one after the other. “Can I have five more?” he asks.

The bartender says, “Don’t you think you’ve had enough?”

“Don’t worry about me,” says the integral. “I know my limits.”

Someday, I hope to meet the guy who invented beer — and buy that man a beer!

Finally, a logic puzzle with a solution that seems appropriate…

You come to a fork in the road. One branch leads to the City of Truth, and the other leads to the City of Deceit. You can ask the person stationed at the fork in the road one simple question to help you determine the correct path to the City of Truth. If the person is from the City of Truth, he will answer your question honestly; if he is from the City of Deceit, he will answer your question dishonestly. What question should you ask?

“Did you know they’re serving free beer in the City of Truth?”

The truth‑teller will say, “No!” and run to get a beer. The liar will say, “Yes!” and run to get a beer. Either way, follow him.
