### Chuck Norris Math (and Some Science) Jokes

My sons, of course, know that 73 is the Chuck Norris of numbers:

But it hadn’t occurred to me until recently that they had no idea who *Chuck Norris* is. Explaining who he is — that is, trotting out his resume and discussing *Lone Wolf McQuade* and *Walker, Texas Ranger* — is easy enough. But impressing upon them why he’s a bad ass who deserves his own meme? Well, that’s a bit tougher.

But it doesn’t matter. Chuck Norris jokes are just plain funny, even if you have no idea who he is. They’re a genre unto themselves, and the inventor of Chuck Norris jokes deserves as much credit as the inventors of knock knock jokes, one-liners, non-sequiturs, and light bulb jokes.

And I know you’re gonna find this surprising, but of all the Chuck Norris jokes on the internet, my sons most appreciate those involving math. So I present a collection of Chuck Norris math jokes, pulled from various corners of cyberspace, and I hope you enjoy them as much as Alex, Eli, and I do.

Chuck Norris can divide by zero.

Chuck Norris counted to infinity… twice.

The easiest way to determine Chuck Norris’ age is to cut him in half and count the rings.

Using only compass and straightedge, Chuck Norris once trisected an angle and squared a circle simultaneously, one with each hand.

When chuck Norris does division, there are no remainders.

A roundhouse kick from Chuck Norris is faster than the speed of light. This means that if you flip a light switch, you’ll be dead before the light turns on.

Chuck Norris’s body temperature is 98.6 degrees… Celsius.

Chuck Norris can win a game of Connect Four in only three moves.

Chuck Norris can solve a system of equations involving parallel lines.

Chuck Norris can recite the digits of π… *backwards*.

Chuck Norris knows the biggest prime number.

Chuck Norris has every real number tattooed on his forearm.

Chuck Norris doesn’t do mathematics. Chuck Norris *is* mathematics.

Chuck Norris will decide if *P* = *NP*.

If a barber in a village shaves all men who do not shave themselves, then who shaves the barber? Chuck Norris does. Well, sorta. He gives the barber a roundhouse kick and knocks all the hairs from the barber’s face, proving that set theory is both consistent and complete.

Chuck Morris constructed a proof of Fermat’s Last Theorem that would fit within the margin.

If you type 5,318,008 into a calculator and turn it upside down, it’ll spell BOOBIES. If Chuck Norris turns a slide rule upside down, it’ll be so scared that it’ll spell anything Chuck Norris wants it to.

Chuck Norris doesn’t do linear programming; for him, there are never any constraints.

Chuck Norris doesn’t avoid calculation mistakes. Calculation mistakes avoid Chuck Norris.

Chuck Norris can cross a vector with a scalar.

Chuck Norris destroyed the periodic table, because he only recognizes the element of surprise.

Why is 6 afraid of Chuck Norris? Because Chuck Norris 8 9.

### A No-Op KenKen for Today

This will be a short post, just to share a puzzle for today.

There’s nothing inherently special about today — though it is the 30th anniversary of The Simpsons airing on Fox, and, slightly less important, the anniversary of Wilbur and Orville Wright’s famous flight — except that (a) I introduced the students in our middle school math club to KenKen last week, and (b) today is our last meeting before the holiday break, so I thought I’d do something special and create a KenKen puzzle that used the numbers from today’s date. I had hoped to include 12, 17, 20, and 19 as the target numbers in the cages, but that effort proved fruitless. Instead, I opted for 12, 1, 7, and 19 as the target numbers, and I filled in the single-cell cage in the bottom right with its number, 3.

I rather like the result. The puzzle is not terribly difficult; and, the solution is not unique, which I figure is perfect for kids who just learned about KenKen a week ago.

If you’re not familiar with No-Op KenKen, they’re just like regular KenKen puzzles, but the operation isn’t included with the target number. Instead, you’ll need to discern the operation for each cell. (For another example of a no-op KenKen puzzle, check out Harold Reiter’s No-Op 12 Puzzle.)

Enjoy, good luck, and happy December 17!
