On a barge is not floating in the Hudson.

Came here to say this.

It ain't no Duck.

Does not appear to have removable stickers.  Too hard for me.

I don't remember Rubix Cube having a brown bottom.

Those are some of the least inspiring cool pics I have ever seen.

I like puzzle.

once got 2 sides completed, gave up after that.  Had a friend that I worked with that solved a cube in about 45 secionds in the dark illuminated only by headlights.  Pete, you are awesome.

I'm actually disappointed it wasn't in the Hudson... Think it'd look a lot cooler that way.

CSB:
I can solve a Rubix cube in under 5 minutes. Once, I did it one-handed (took me 15 minutes). I keep one on my desk at work - people are reluctant to "mess it up", even after I tell them I can solve it easily. Usually, that leads to a short conversation during which I solve the thing. (It actually sets my teeth on edge to see one unsolved anymore.)

A rabbi taught me how.

end CSB. NO WAIT-

OddLlama: I like puzzle.


NOW end CSB.

Just wait till NYPD discovers it's a cover for a drone.

If they're not going to be solving it on the way, it's not worth the effort.

Cpl.D: I used to be able to do 'em under a minute.


Mine was 36 seconds (30 years ago...).  I have no idea how people do it any faster because that was probably the best I could ever do.  My average time was about a minute +/- 10 seconds.

My favorite configuration is this cube-within-a-cube-within-a-cube, each shell rotated.  It's much harder to do than simply knowing a bunch of algorithms to solve the cube, because you have to know a move that puts _this_ piece _there, and what other pieces it will mess up when you do that.

So, the cube sucked a flock of geese into its engines?

So, you just need a different set of algorithms.

The most cruel joke you can play on some one who just discovered the rubics cube is to peel off random color stickers and move them around so the puzzle can never ever be solved.

wallywam1: So, you just need a different set of algorithms.


I'm not sure that I have a set to start with.  I just have a bunch of moves - to rotate/swap these cubes, do this.  Almost every time, I have to re-examine the cube to see what my next move needs to be.  "Oh, I need to put this corner piece here. Bam.  Oh, I need to swap these edge pieces. Bam."  That rotated-subcube structure I came up with is hard because I usually have to move one or two pieces to figure out what my next move needs to be.  Doing that figure takes me about 20 minutes because after each move I have to figure out where the hell I am. What I can't do/understand are people that can look at a full cube and then solve it from there, without further looks. As inefficient as my method is, it's still pretty damn fast.

I am not good at chess.  But then, I earned my moves.  I figured out how to move X to Y, and I only have three moves of complexity, one of which I couldn't recall until spontaneously a few minutes ago and the third of which is "Rubik's Move" I got from a book for flipping two edge pieces in a plane.  The other two swap two corner pieces without screwing up the top (hardest one I just remembered) and rotate 3/4 bottom layer corner pieces without moving any.

There was actually a Scientific American article in (1984?) about how Rubik's Cube corner rotation matched with quark charges - you could have any number of 1/3 changes as long as they added to an integer.  3 1/3 clockwise rotations, or one 2/3 CCW and one CCW rotation, both were good. You couldn't do a move that only had a net 2/3 corner movement, just as no particle has a net fractional quark charge. You'd think they wasted a lot of brainpower on that issue, but using a corner-cube model to match against quark charges is better than the currently-accepted theory, which is "we have no f'ing clue that we can prove".

Not so fun fact: The Narrows is where The Scarecrow drugged Batman and he (the Goddam Batman),freaked out and got burned.

/FACT!
