For a refreshingly straightforward point of view from a young person in the field who just wants to get on with doing some good physics with what seems like a promising approach, read Jonathan Shock’s description of his recent attendance of meetings (including the one to which I earlier referred) on heavy ion collisions and related physics. (See also an interesting comment by Xin-Nian Wang on the comment thread of my earlier post.) Jonathan gives some useful links to presentations on some of the attempts to model some of the new physics using string theory models.
The title? Oh, yes, he gets beaten up a bit by those around him for working on strings. Get used to it Jonathan. Some (fair) criticism is good though. Learn how to defend what you are interested in working on by appealing primarily to its merits. That’s all you need.
Just remember:- If it does not kill you, it will make you strong.
