Kansas Classrooms

I can’t teach you about safe sex because it might encourage you to become promiscuous.

I can’t tell you what airbags do. That information will make you think it’s okay to start crashing into things.

I’m sorry class. We can no longer study Mexico. As you’d all run away to Tijuana if I told you what was there.

If I teach you girls how to rescue a burnt casserole, how can I trust you to follow the teachings of Héloise?

I’m afraid I can’t tell you how Hannibal crossed the Alps. If I did, you crazy kids are likely to conquer the prom with elephants. Oops.

Trigonometry will no longer be taught. You could use that knowledge to calculate the trajectory of eggs thrown at my Geo Metro.

We won’t be using safety glasses this year in shop class. I believe anyone who gets a word chip in their eye have it coming.

Science has been cancelled because your parents prefer to believe in magic.

On Infinity

“If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those who live in the present.”

– Ludwig Wittgenstein

Hypotenuse [Noun.]

In geometry, the side of a right triangle opposite the right angle.

“About binomial theorem I’m teeming with a lot o’ news,
With many cheerful facts about the square of the hypotenuse.”
– Gilbert and Sullivan, The Pirates of Penzance (1879)

On Two Outcomes

“There are two possible outcomes: if the result confirms the hypothesis, then you’ve made a discovery. If the result is contrary to the hypothesis, then you’ve made a discovery.”

– Enrico Fermi

Rubik’s Cube

The Rubik’s Cube is a 3D combination puzzle. It is the brainchild of the Hungarian professor of architecture Ernő Rubik, who invented in it 1974. Since then, over 300 million Rubik’s Cubes have been sold worldwide. If they were stacked on top of each other, they would reach the top of Mount Everest, twice.

It is estimated that in the mid-eighties about a fifth of the world’s population had, at some point, handled a Rubik’s Cube. And because of its simple design, people continue to be astounded by its devilish complexity. The percentage of people that has ever solved the Cube, is more somewhat more difficult to ascertain.

Obviously, there is only one solution in which all six sides of the Cube have the same colour; as for all the different unsolved states, the original 3x3x3 Cube has 43252003274489856000 (that is to say, over 43 quintillion) possible Cubes. If there was a Cube for every permutation, they would cover the Earth with 273 layers – a sea of Cubes 15,5 meters (50 foot) deep. If there was a cube scrambled for every permutation and they were laid end to end then they would stretch approximately 261 light years – from Earth to Alpha Columbae.

Because of the vast amount different Cubes, algorithms (a sequence of moves that has a desired effect) are used to solve the Cube. Without algorithms to solve the Cube, it could take ages: if you made a single turn of one of the Cube’s faces every second, it would take you 1371,51 billion years to go through all the possible configurations. The universe is only 13,82 billion years old. If you had started this project during the Big Bang, you still would not be done yet.

Amazingly, the best speed cubers (people who take part in speed cubing – a sport where competitors try and solve the cube as quickly as possible) can solve the cube in under six seconds. At the time of writing, the world record is 4,90 seconds; the record for blindfolded solving (including memorization beforehand) is 21,05 seconds.

Mike: Look I don’t know, ok; it’s like a fucking Rubik’s Cube! I mean, it’s impossible at this point.
Selina: What? Mike, a Rubik’s cube is not impossible to solve.
Gary: Yeah, I saw an Asian kid do it in like ten seconds.
Selina: Ten seconds Mike.
