Why Life is Physics and not Chemistry

... and never even mind Biology :)

Here is note about the article: "http://www.technologyreview.com/blog/arxiv/26059/"

And here is the article: "http://arxiv.org/abs/1011.4125"

So far, I've just read the note and the abstract ... but I've now downloaded the article and am going through it now.

This really looks grand.

Some Excellent Posts


In the course of thinking about the limitations of logic and mathematics I've read many posts.

Here are three that seem to me to pull a lot of things together:

"The Vagueness Paradox" - A post by Terence Tao that brings together a lot of stuff (in combination with a couple of Wikipedia articles - see the next two links.)

"Tarski's Undefinability Theorem" - A link to this page is in the post by Tao.

"Diagonal lemma" - A link to this page is in the Tarski article.

I said in some post quite a while ago that I thought things could be sorted out by carefully thinking about how it all fits together. Well that is indeed the case as illustrated by these posts and articles. Here is a link to my thoughts about a "A Gödelian Puzzle".
