I (and I believe the OP) had hoped that it would give people some mental juice. Especially, I was trying to get people to understand the underlying concept, and see that it crops up in places seemingly not related to robotics. I had hoped to get some ideas to collide in people's minds, so that they would start looking for patterns and connections. I believe it was Picasso who said "Computers are useless. They only give answers." Well, I disagree with him. But I think he had a point. Mathematics is the science and art of noticing patterns and correspondences where one would not normally expect to see them.

I don't speak for Alcatel <- They make me say that. ``` Previous message: [DPRG] Re: Robot math problems Next message: [DPRG] Robot math problems Message index sorted by: [ date ] [ thread ] [ subject ] [ author ] More information about the DPRG mailing list
