A thing of beauty

Sabine Hossenfelder's new book, Lost in Math:  How Beauty Leads Physics Astray is stirring up quite a stir with multiple reviews.  Hossenfelder has recently stuck her oar into the question about whether a new supercollider should be built as a follow-on to CERN.

The just-look-argument is of course well and fine. But, as I have pointed out many times before, the same just-look-argument can be made for any other new experiment in the foundations of physics. It therefore does not explain why a larger particle collider in particular is a good investment. Indeed, the opposite is the case: There are less costly experiments for which we have good reasons, such as measuring more precisely the properties of dark matter or probing the weak field regime of quantum gravity.

Eli got into this a little bit on Twitter

Think of it as the argument btw theory: Go here and experiment: Cast about. When there is no indicative theory you cast about.

You are making an economic argument not a scientific one.

but the issue of beauty in physics, in science in general, what is worth doing, at least to Eli is of interest.  About a month ago the Rabett in a comment to Hossenfelder thought that beauty in physics was a matter of being terse, spare simple.  She really did not like that, and after all, who is Eli.  Reading the New Yorker this week a rather better description appeared in James Marcus' memorial to his father, a bioscientist, who died a difficult death.

Later, after his death, one of his colleagues noted that my father "believed that beauty would save the world".  My father would never have said that about himself.  Yet it was true, if you understood beauty to encompass not only ecstasy but precision, rigor a relish for the tiniest (literally microscopic) details. And it was true about me, too. We were a religious sect consisting of two people, and now half the congregation was gone. There would be no closure, no healing. I would simply adjust myself to a new and severely depleted reality. The world would come to an end, as it always does, one world at a time.
