Thread: Solved the Rubik's cube in a little over .6 seconds.

1. Solved the Rubik's cube in a little over .6 seconds.

Wow. Not awesome, but still wow.

2. Saw that, wow indeed.

What's far more wow imo is the human record is under 5 seconds! I've never timed myself, but it takes me probably 3-4 minutes to solve. In 5 seconds I've hardly got the first piece in place, the speed guys are simply amazing.

Oh and hey, if you're not a Belieber, he can do it in around 2 minutes

3. Mine time is about 20 years and holding..

You might enjoy this article then. It includes a link to a story about a guy who finally solved it after 26 years!

It also mentions 2 other records:
One-handed < 10 seconds;
Feet-only < 30 seconds.
I can't even imagine...

There are lots of YouTube videos about solving, but the quality is very variable. If you want an easier puzzle to start with, I recommend the 2x2 cube or the "Pyraminx Pyramid". Solve one of those and you'll immediately find out if you have the bug

5. Graham Parker, a builder in Hampshire, solved it in 2009 after 26 years of trying. He wept when he completed it. It had caused him backache and put a strain on his marriage, he admitted.

Sounds safer to just continue ignoring it!

6. Yeah, the "backache" is a puzzler.

7. It usually takes me between 1minute 20 seconds to 2 minutes to solve. Never figured out how the speeders do it (watched several videos and still don't get it; lol).

You're fast. I saw/read once that the speeders memorize ~60 different algorithms, so they have an immediate solution to apply once they get a look at the cube. These algos are apparently very different from the simplest beginner's approach I use.

The second part of the speedsters performance is the physical side of it.
First, a cube which they've customized for speed--mostly the right lubrication for turning without sticking, and the right tension for not over-turning iirc.
Second, they don't really hold the cube like we would, they more sort of spin it in place with very dexterous and precise finger movements. Reducing hand & finger travel is vital to achieve such ridiculous speeds, since a minimum of 20 turns are needed.

The third part of course is the obsessive constant practice.

9. Here's a puzzle everyone here can solve. lololol

Looks easy, doesn't it? But there are 6 sides--the picture is very deceptive, showing only 3

This means that instead of 1^3 possible solutions, there are in reality 1^6! So it'll be quite a challenge. What's your best time?
