Poincare Conjecture

Post by Dale »

http://news.xinhuanet.com/english/2006- ... 644754.htm
Two Chinese mathematicians, Zhu Xiping and Cao Huaidong, have put the final pieces together in the solution to the puzzle that has perplexed scientists around the globe for more than a century.

The two scientists have published a paper in the latest U.S.-based Asian Journal of Mathematics , providing complete proof of the Poincare Conjecture promulgated by French mathematician Henri Poincare in 1904.
I must be doing something wrong. For years, I've worked on this and I keep getting "7".

Was that 7 base 8 or 7 base 10?

"The conjecture is that if in a closed three-dimensional space, any closed curves can shrink to a point continuously, this space can be deformed to a sphere," he said.
That's nice.

Yeah. It is. It kind of warms the cockles of your heart-not the mussels maybe, but certainly the cockles.

What's wrong with 7? Doesn't warm the cockles?

Dale, I've reverse engineered your thought process (easy enough, knowing your "answer"). You'll kick yourself! You just forgot to invert the divisor before multiplying! Hey, it happens, especially to people not used to working in that third dimension...

DAMN IT!! Again, one simple mistake keeps me from uncovering profound truths!

Have you considered sticking with superficial truths?

Rats. I tried to read the partial proof but couldn't get past the second sentence of the abstract, so I went and looked around in the garage, instead. I’m pretty sure this is the real answer, but I don’t know how to write it up, so I guess I’ll have to concede to the Chinese dudes. And there's another frickin’ Nobel down the drain.

Darn! I almost had this worked out. I was so close. I only needed a few more days...

That is a picture of a two-manifold.
