84. Rubik’s Cubes
My friend Andrea, always thinking, sent me a message saying she just got a Rubik’s Cube. And what’s a Rubik’s Cube? Rectangles upon rectangles upon rectangles! I asked Andrea if she wanted to guest-write an article for TTAR on the elusive Cube. Here’s her response:
“I don’t know how to write articles. But I did find some fun facts about cubes. They were discovered in 1974 by a Hungarian named Erno Rubik. He was a sculptor and architect. Originally, they were 3x3x3, but they come in sizes 2x2x2 all the way up to 7x7x7.
There are competitions involving Rubik’s cubes called speed cubing and include things like solving them blindfolded, solving them with one’s feet, one handed, team blindfolded solving, and underwater Rubik’s cube solving. There are also promo cubes, and spherical Rubik’s cubes.
That is all. Oh, but other things in my room that are rectangles include a box of lucky charms, my windows, my notebooks and school stuffs, a one dollar bill, a metal box with little bees on it, my bulletin board, and some bumper stickers that I stuck on my wall.
Yep. So that was probably not that interesting, but by far a better spent 20 minutes than the homework (also rectangular) that I should be doing.”
Thank you, Andrea. That was interesting, and now let’s explore the Rubik’s Cube some more.
So, who is Erno Rubik?
Erno Rubik (born July 13, 1944) is a Hungarian inventor, sculptor and professor of architecture. He is best known for the invention of mechanical puzzles including Rubik’s Cube, Rubik’s Magic, Rubik’s Snake and Rubik’s 360.
Wait, what are those things?
Rubik’s Cube, Rubik’s Magic, Rubik’s Snake and Rubik’s 360, you mean? Well. Let’s see what Wikipedia has to say.
“In a classic Rubik’s Cube, each of the six faces is covered by nine stickers, among six solid colours (traditionally white, red, blue, orange, green, and yellow). A pivot mechanism enables each face to turn independently, thus mixing up the colours. For the puzzle to be solved, each face must be a solid colour. Similar puzzles have now been produced with various numbers of stickers, not all of them by Rubik. The original 3×3×3 version celebrates its thirtieth anniversary in 2010.”
Here are pictures of the other three “mechanical puzzles.”
