Go up one level in this thread


I have choosen a very intuitive approach - I mean  if you look at books about
Lie groups / group theory - they are abit cryptic - to say the least.

I want to come away from plies and trees -  the human brain is good in pattern
recognition, but very bad in precise calculations.

The whole thing I have in mind is so fuzzy so far, that I would not bet a single
cent on anything like " progress " - not to speak of an sulution.

It is like an unskilled rock climber trieng a big , foggy mountain on a planet
in a foreign galaxies - that means it is just a myth so far.

I keep on researching -   all dreamers , leisure mathematicians, hopeless fools
: wellcome !

Everybody else - try to make a living !!
