We still make mathematical errors that are later corrected with coefficient renormalizations. We still have no idea how to construct correct equations without invoking never observed "bare" particles.<br /><br />http://vladimirkalitvianski.wordpress.com/2013/01/06/popular-explanation-of-renormalization/Vladimir Kalitvianskihttps://www.blogger.com/profile/16310670038267361671noreply@blogger.comtag:blogger.com,1999:blog-5237654928835551390.post-72931506733759142952012-12-31T18:48:13.479+00:002012-12-31T18:48:13.479+00:00Anonymous, let me clarify my statement:

So please just go to some other place to play your stupid "I am smarter than you" games.<br /><br />No woman would ever write such a comment. But your attitude has a side-effect: you will never achieve anything in the search for a theory of everything with your attitude. (See the example of Lubos Motl, who fell into the same trap.) Find another field for you.

This kind of lets down your post, scattering amplitudes are regularly measured, and have been for a long time, in many different contexts. They have proven a very good experimental tests for theories, such as the standard model.

No day is passing by without pompous and grandiose speculations showing up in Arxiv and physics blogs. The vast majority of these ideas cannot be falsified. They are baroque but "empty" mathematical constructions with little to no contact with physical reality. Firewalls, landscape, Black Hole entropy, anthropic principles, multiverses, large extra-dimensions, loop quantum gravity, M-theory, holography, GUT models, twistors, E(8), scattering amplitudes, entropic gravity, octonions, quaternions, Clifford algebras, deformed Special Relativity and on and on...What a troubling hodge-podge of dead-end attempts to go beyond the Standard Model!<br /><br />Shifman was right in saying that what we are seeing is a lost generation of theorists in denial and fighting for their careers... <br /><br />Cheers,<br /><br />Ervin Ervin Goldfainhttps://www.blogger.com/profile/07585008304556273617noreply@blogger.com
