# When We Cease to Understand the World **Benjamín Labatut** | 2020, translated from the Spanish by Adrian Nathan West | Fiction built on fact --- Five pieces that start in documented history and slide into invention, about the scientists and mathematicians whose discoveries ran ahead of what they could bear to understand. Fritz Haber and the chemistry that runs from Prussian blue to cyanide, Karl Schwarzschild solving Einstein's equations from the Russian front, Grothendieck and Mochizuki at the edge of mathematics, and Heisenberg and Schrödinger fighting over what quantum mechanics means. Under every chapter runs the same question, what a discovery costs the person who makes it once the math works and the meaning goes missing. --- ## Currently Tracking - Where Labatut's fact ends and his fiction begins, and why he blurs the line on purpose - Discovery as something that happens to a person, with the cost landing on them - Mathematics and physics that outrun the people who find them - Heisenberg's matrices against Schrödinger's waves, and the quarrel underneath them --- *Notes and highlights in progress.*
