Science vs. Religion: (Chapter One) (Humans)

I have only just begun, but right away I wanted to clarify something. On pg 15, where you reference Godel's theorem, I need to correct what it seems Paul Davies was suggesting. Of course I'm correcting him once-removed.

> We are dealing with my very incomplete math background. I've recently bought a calculus course to put on my computer and study.-David, -Don't be hard on yourself, you were quoting Paul Davies! The only possible error on your part was in taking him at his word; after all, physicists tend to be pretty good at math. This doesn't however, mean they're mathematicians. But I don't consider this a fault of yours.-Hawking for example has long since abandoned the idea of a "theory of everything" after having given much thought about Godel's incompleteness theorem. It is at the centerpiece of my criticism of String Theory. If String Theory is found to be complete, it will necessarily be inconsistent. -Calculus is good--by all means--but in all truth it won't get you to "real" math. (Not that calculus isn't 'real,' only that in most cases a course in calculus is targeted for engineering computations and not for abstract mathematics--ie Godel.) I would suggest this book to build the comprehension needed to tackle more abstract ideas. I can suggest others (and cheap others) beyond that, if it suits you. And if you choose to get that book, get it used... the current list price is atrocious...

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
