The geometry of space-time (Schwarzschild metric) may be represented as a tetrahedron. Please see my Sat, 12 Nov 2011 05:19:08 GMT JessT http://groups.yahoo.com/group/tetrahedronT3/message/282 http://groups.yahoo.com/group/tetrahedronT3/message/282 Hoping for a speedy healthy outcome. I've had some neurological issues myself, mostly having to do with hearing and vision, but nothing permanent so far.

I had a stroke a few months ago, however I am recovering now. The following is a little off topic however I Mon, 04 Jul 2011 09:09:44 GMT Melinda Green http://groups.yahoo.com/group/tetrahedronT3/message/280 http://groups.yahoo.com/group/tetrahedronT3/message/280 Wow, that's quite a news story! It's amazing to me that just about everything about it is positive. Not so much for poor China though as you point out.

I am a little off topic again. The Einstein Field Equation (EFE) may be simplified. A tensor may be substituted by a ratio of stress and a scalar may Wed, 06 Apr 2011 20:54:27 GMT jess tauber http://groups.yahoo.com/group/tetrahedronT3/message/273 http://groups.yahoo.com/group/tetrahedronT3/message/273 This is the Leftmost-Leftmost system, which is that of most of the magic numbers that we usually think of in the nuclear system: 258- 184= 74= 72+2 184- 126= Tue, 05 Apr 2011 17:56:46 GMT JessT http://groups.yahoo.com/group/tetrahedronT3/message/272 http://groups.yahoo.com/group/tetrahedronT3/message/272 The nuclear shell filling pattern can be idealized as blocks somewhat analogous to what is seen in the electronic system, but organized differently.
