Garrett Lisi in 10 Years:
Garrett Lisi is responding to criticism and his critics over at Peter Woit's Not Even Wrong weblog, which means we get a double-dose of Lisi this month, as his article with Harvard-educated physicist Jim Weatherall is featured prominently in this month's issue of Scientific American.

Lisi's version of E8 Lie Algebra, as far as I can tell, is an attempt to build a background upon which, with further development, the fundamental particles that we know exist today, with their exact masses, charges, and chiral behavior for those particles that behave so, will emerge. It has not accomplished its goal as of yet, but it is early and needs more work, as Lisi himself has stated right from the beginning.

C;ick here for Lisi's Elementary Particle Explorer and have some fun in Physics for a change.
I personally as a lifelong professional student have no idea where this theory is going. If it goes the way of Epicycles as its critics claim it is, then so be it. A great day will then come when the theory is disproven, as disproofs aka "falsifications" are often as famous as proven theories, as Michelson-Morley and Stern-Gerlach attest.
But if true, we are at the dawn of a really good thing.
I wish to see more people explore this theory. Its recent interest into triality is particularly exciting to me personally. The number 3, I have always felt, occurs with a bit more regularity in nature than it should. Is there something there? It will always occur more than 4 and less than 2, its neighboring integers, but seems to express itself moreso than that which would nicely fit its place in a first quadrant hyperbola bar graph of integer occurrence, regardless.
We'll see. Mathematics is beyond exciting once its frontiers are studied, and its seemingly limitless applications to Physics seem beyond the surreal. It is truly a beautiful world and E8 symmetry is likewise lovely. So let it be written, so let it be done.
Which reminds me, the picture above is not of Lisi but of the great actor Yul Brynner in "The King and I." "Men of a certain age" such as myself know this, I just remind us that young people exist who never knew of him. Youth is noone's fault, but that doesn't mean it is nevertheless an affliction. Father Time has the cure, be patient, like we all have to be as we await the further development of Lisi-Lie E8.
