If computers can do all this and solve puzzles that have plagued our minds for centuries, where will the limit be? Perhaps one day the effect of a drug in a patient or the release of software into a market will be fully simulated through computation.

Unless you believe there is something inherently "magical" about human beings (i.e., we have a soul) then we are simply following the laws of physics which determine how the matter and energy in our bodies will behave.

Does that mean we could simulate human society? Maybe. The effects of the uncertainty principle, quantum mechanics, random radioactive decay etc. mean that you can't do it perfectly, but how well you can do it depend

To say that we "follow" the laws of physics gives a misleding connotation. Physical "law" decribes how things act, it doesn't determine how things act.

You see, people have a misconception that the world can be divided into natural and manmade. It's an easy mistake to make that is ingrained in our way of thinking. Look at foods and cosmetics being touted as "organic" or "natural" when they really just mean that humans haven't screwed around with what was already there.

But seriously, I think that this will be the case. There is no compensation required by a diagnostic program.

I see some form of this happening in my lifetime.

Most of them are easily derived from other solutions, by swapping, reflecting, and rotating various sections. With a systematic approach, I'm sure that Archimedes, or anyone following him, could have listed all the distinct solutions within a few weeks of work."

I couldn't be less interested in the notion that a computer barfed out all possible solutions. Somehow I imagine we are being denied the real interesting part of this. What seems interesting is the parts mentioned about how certain pieces were always found in a pair. I'd also be interested in how one solution maps into another solution. What clumps and individual parts can be interchanged. Also, someone should do one that fits on the surface of a sphere. (though, probably already been done)## WRONG (Score:5, Funny)

For example the fact that the vast majority of 536 solutions are bilaterally symmetric suggests that the first cut in the creation of the puzzle was right down the middle. I'd also wager that cuts that bisect fragments are more likely than cuts that nick a fragment. Such straight-line, bisecting cutting behaviors are more likely than cutting polygons out of the middle of the whole square.

It may be a math puzzle solved by a computer, but I wonder if we can learn something about how people think from it.

Assuming the pairing that you describe, bilateral symmetry would multiply the number of seemingly unique solutions by a factor of 8.
