🧮 Neutrinos Lead to Unexpected Discovery in Basic Math

As long as you consider linear algebra and eigenvectors “basic math”:

They’d noticed that hard-to-compute terms called “eigenvectors,” describing, in this case, the ways that neutrinos propagate through matter, were equal to combinations of terms called “eigenvalues,” which are far easier to compute. Moreover, they realized that the relationship between eigenvectors and eigenvalues — ubiquitous objects in math, physics and engineering that have been studied since the 18th century — seemed to hold more generally.


Quanta, Relativity, and the Nature of Reality

It’s quite a daunting task to explain anything in theoretical physics in 250 pages, but this is just what I like about Carlo Rovelli’s books. Earlier this year I read The Order of Time, and like that book, Reality is Not What it Seems gets right to the point. No time is wasted or point too embellished.

This time around Rovelli tackles his specialty: quantum gravity. While it is a work of popular science, he does an admirable job of explaining wildly complex theories — made all the more difficult because a...
