On Reading The Age of Entanglement

Posted by jns on 21 May 2009

Reading proceeds apace, but writing about the books seems to happen in big clumps. For instance, my book note on Louisa Gilder’s The Age of Entanglement : When Quantum Physics was Reborn (New York : Alfred A. Knopf, 2008. xvi + 443 pages). Perhaps if I wrote less I could write sooner.

Oddly, I didn’t realize how much I had enjoyed the book until I wrote about. I found it quite engaging and, despite the author’s defensiveness about writing narrative nonfiction (and her queasiness cause me a bit of queasiness at first), I thought it was not only engaging but high in scienticity. She’s done a very careful and thorough job with keeping her science precise, and I thought she showed quite a depth of understanding in what is described as her first book.

From my collection of quotations noted but unused in the book note, this one about the distinction between a theoretical physicist and an experimental physicist. It’s pretty much true, but a bit of reflection makes it unsurprising.

“How do you tell an experimental physicist from a theorist?” asks [experimental physicist John] Clauser more than thirty years later, in his northern California desert home encrusted with sailing trophies and plaques. Running his finger along the thick spines of schoolbooks, he beings to answer his question: “A ”theorist” will have: lots of textbooks (the experimentalist will have some engineering ones, too).” He taps these with his finger. “Lots and lots of ”Phys. Rev. Letters.”” In fact, a bookshelf taking up a whole wall is crowded with the pale green journals. “Biographies of the great, and books written by them.” Clauser gestures through the door of his wood-paneled office. “But the ”experimentalist” will have”—he turns: here, in the hallway beside the kitchen door, is another floor-to-ceiling bookshelf, packed with rows and rows of narrow, shiny softcover book spines in garish fluorescent colors—””catalogues.”” He grins. “Anything I need to make, if I don’t have the pieces already, I look for it here. I can make anything.” [pp. 260—261]
