String Theory Backlash

Sharon Begley has an interesting column today in the WSJ on the growing chorus of voices aiming to discredit string theory.

String theory isn't any more wrong than preons, twistor theory, dynamical triangulations, or other physics fads. But in those cases, physicists saw the writing on the wall and moved on. Not so in string theory.

"What is strange is that string theory has survived past the point where it should have been clear that it wouldn't work," says Mr. Woit. [Professor Peter Woit of Columbia University] Not merely survived, but thrived. Virtually every young mathematically inclined particle theorist must sign on to the string agenda to get an academic job. By his count, of 22 recently tenured professors in particle theory at the six top U.S. departments, 20 are string theorists.

Having just read a review copy of Lee Smolin's new book The Trouble With Physics, I must confess that I'm convinced. Smolin argues that string theory is responsible for the failure of physics to "make any real headway in the last 30 years." According to Smolin, string theory is slowly strangling particle physics, and moving a fundamental science into the realm of metaphysics. Woit's book, which is due out this fall, has a damning title: Not Even Wrong.

Begley ends her article on a harsh and sobering tone: "That string theory abandoned testable predictions may be its ultimate betrayal of science."

Have a look at this article from the current New Yorker. It focuses on the recent anti-string theory books from Lee Smolin and Peter Woit. The article provides a decent summary of Smolin's and Woit's views, but it is seriously marred by the lack of any contrary views of the matter. The views…
I finished Lee Smolin's The Trouble With Physics last night, and will write up a full review in the next couple of days. On the whole, I thought it was a well-done book, and he makes some good points. It's not without its problems, though, chief among them being the fact that the title is missing…
The two most talked-about books in physics this year are probably a pair of anti-sting-theory books, Lee Smolin's The Trouble With Physics, and Peter Woit's Not Even Wrong, which shares a name with Jacques Distler's favorite weblog. I got review copies of both, but Not Even Wrong arrived first (…
Lee Smolin's The Trouble With Physics is probably the hot physics book of the year. Granted, that's not saying very much, relative to whatever Oprah's reading this week, but it's led to no end of discussion among physics types. And also, frequently, the spectacle of people with Ph.D.'s squabbling…

String theory is just a theory, not a fact! Teach the controversy!

Oh, wait, that sounds right this time.
