Not realistic. What technological advance has ever been restricted to only the rich? Even now, it costs under $1 per base pair to get a piece of DNA made to order. People will be selling it to the poor within a few years of selling it to the richer early-adopters, same as everything else.

P.S. Your cartoon indicates you need to read Atlas Shrugged.

Any technological/social method to compensate for less-beneficial genes (allowing the individual to reproduce anyway) is obviously taking away the effect of natural selection. Including vision correction, cancer treatment, etc. The population boom of the last few centuries is made of people who wouldn't have survived without modern advances, for whatever reason (though not necessarily genetic reasons in all cases). Without advancing technology it would be a bleak picture and you would be led to advocate eugenics. However, with advancing technology, we'll be able to genetically engineer out unwanted mutations within a few decades, so it doesn't really matter.

according to video "Root of All Evil?: The God Delusion" they said "45% believe that earth has existed for 10'000 years" I think this means 45% of Americans are Christians

I've also posted this at PhysicsForums I'll be putting any new pages up there (new pages probably won't be for a while)

If you're doing stuff with a whole bunch of tensors, lot's of contractions, etc, then the diagrams are much easier to look at and work with.
Of course there's nothing that you can't do with the original notation. I just like looking at diagrams much more than a long line of algebra.

I'd have to draw the diagrams by hand anyway. Powerpoint would just make this harder!

And this is the last one.

The topics not included are derivatives and Lie Algebras. I don't have anything written on those yet, and it will probably be a while until I do. I probably won't be posting them here unless people really want them (but it seems like there are only a handful of people who would care)

Eh, if you want it up on Rapidshare, you can do it.

The rest of this is on how to compute components of tensors.

I don't think anyone will care if I go away for half an hour - this is a good place to take a break

And here is one place where the notation really shines over the standard notation
