Rubik’s Cube is 40 years old
Invented in 1974, patented in 1975 and released for sale in Hungary in 1977, Rubik’s Cube could certainly be considered to have reached its 40th birthday this year. To celebrate, inventor Ernő Rubik has helped put together a special exhibition at Liberty Science Centre, New Jersey, celebrating the history of the hexahedral enigma. The exhibition, called ‘Beyond Rubik’s Cube’, opens on 26th April for several months.
How to solve a Rubik’s Cube in one easy step
Note: If you’re looking for instructions on solving Rubik’s cube from any position, there’s a good page at Think Maths.
One day some years ago I was sat at my desk idly toying with the office Rubik’s cube. Not attempting to solve it, I was just doing the same moves again and again. Particularly I was rotating one face a quarter-turn then rotating the whole cube by an orthogonal quarter-turn like this:
Having started with a solved cube, I knew eventually if I kept doing the same thing the cube would solve itself. But this didn’t seem to be happening – and I’d been doing this for some time by now. This seemed worthy of proper investigation.
The Magic Cube – a 3D logic puzzle
A chap called Jonathan Kinlay has innovented a Rubik’s cube variant which only has one colour, but six different integer sequences on its sides. As a colourblind integer sequence enthusiast, this basically has to be my ideal Christmas present, right?
Well, it’s currently looking for funding on Kickstarter in advance of actually existing, and the first units won’t be delivered before Christmas, but it’s a fun idea anyway.
Rubik’s Cube in Minecraft
The last time we posted about Minecraft, someone had made a scientific and graphing calculator. But now someone’s made something actually useful: a Rubik’s cube!
Mastercrafter SethBling uploaded this video showing his fully-working Rubik’s cube, created entirely from standard Minecraft blocks:

World Record Rubik’s Cube Solve
This Wednesday, friend of The Aperiodical Matt Parker compered an event at London’s O2 Arena in which the world record for most simultaneous Rubik’s cube solves was smashed by a crowd including schools groups, individuals, maths fans and the UK’s current speedsolving champion, Robert Yau.
Rubik’s Tube
Numberphile filmmaker and general internet legend Brady Haran has been busy putting together a series of YouTube videos about the Rubik’s cube, with contributions from Aperiodical friends Matt Parker and James Grime. The videos also feature lots of solving clips sent in by viewers, and Aperiodical Editor triumvir and sometime maths-talker-abouter Katie Steckles (that’s me) occasionally pops in to make comments and state facts which are no longer true (a world record was broken 4 days after filming).
