Rubik's Cube Now Solvable in 20 Moves

Posted by CmdrTaco on Monday August 9, 2010 @03:30AM from the good-use-of-spare-time dept.

A few years ago we reported that it had been proven that Rubik's Cubes could be solved in 23 moves. Well now that number is down to just 20. Proving it required 35 years of computer time donated by Google to get it done.

Enough with the Rubik's cube junk, someone please tell us how to unhook a bra with *1* move.

  Easy.
  Step 1:
  Unhook the bra
  It's all relative - what do you consider 1 move? I came across this argument during my first DnD session, and subsequently, haven't played it since.

  You gotta do what I did in 8th grade...find a girl who wanted to learn how to unzip a fly with one hand, and was willing to let you practice taking her bra off with one hand.
  I haven't seen her in well over a decade, but I hope her training paid off. I know mine did!

  All good /.'ers seek knowledge. Whether we ever get to *use* that knowledge is another discussion.

  Placing the hand such that the forefinger is bent against the section of the bra closest to the back and the thumb is over the piece in the foreground with the hooks, slide in the detaching direction with the thumb.
  Alternatively, just ask her to take it off for you ... but that may be a problem if you didn't actually know the girl on the bus in the first place.

  He actually only needs to know how to unhook a bra because it's currently holding a bundle of Cat6 together.

  That's just unhooking, not removing. Removing in one move is best accomplished through the brute force method. Grab the side opposite the clasp and yank hard.

  You do realize that some of them have FOUR hooks, right? Sure it is easy on the one or two hook models for the smaller chested women. But on the 4 hook models for the larger chested - I defy you to do it with one hand in one "move"...
  
  Bring me a large-breasted woman and I'll show you how it's done!

  I'm imagining this game session.
  You: "Alright, I'll unhook the wood nymph's bra."
  DM: "Okay, how do you do that?"
  [rest of gaming group listens intently]
  You: "Umm...I just, you know, unhook it?"
  DM: "Okay, we'll say it takes three rounds."
  You: "It doesn't take three rounds to unhook a bra!"
  DM: "Well, it takes your character three rounds."
  You: "That's bullshit. Have you ever done it?"

  I never said it wasn’t easy. What isn’t easy is doing a “mirror symmetric problem” with no practice.
  Saying the alphabet backward is easy too, but that’s because I practiced it.

Moves 1 through 19: repeatedly hit cube with hammer
Move 20: reassemble the smashed bits into a solved cube.
Warning: Your cube may or may not remain functional through use of this solution.

  1) Turn one face 45 degrees
  2) Pry upward on one middle edge piece until it pops out
  3) Remove all edge and corner pieces
  4) Put the cube back together, but flip exactly 1 edge piece
  5) Give it to someone who knows how to solve it
  6) Laugh maniacally when they just can't seem to get that last piece where it belongs.

It can be shown that a cure for cancer can easily be derived from a method of solving any Rubik's cube in 19 moves.

When I was about six years old, my cousin challenged me to solve a scrambled Rubik's Cube. The family figured it would keep me busy for hours.
I solved it in the fastest possible way: I pulled off every sticker and put them on the right sides.
Problem solved; it wasn't MY fault they didn't define the problem properly.

It's REAL science! Hemp also cures cancer and water fluoridation is really dumping toxic waste in our water supply. The moon landings were faked too because they took too many nice pictures, and the smallpox vaccine is actually made from cowpox, so there's no chance it could possibly create the same antibodies needed to kill smallpox. Also, joint pain can be cured remotely by any well-trained chiropractor.
