3/3 the first 100 pliers, then the next 100, and the last 32. You need different kinds of tape (Scotch, then packing, then duct) in each section, but after 100 more technicalities, you’d have your contraption. Press the first plier down, hard as you can, and pop goes the nut.

2/ seems impossible. He’d make pliers from scratch, and observe that they amplify force, but only by 1%. So coupling 232 of these will amplify force by (1.01)^232=10.06, plenty. Problem is, they don’t couple well. So he would build a contraption to hold them, in three parts,

Thought about Grothendieck vs Bourgain some more; my analogy would be more like: Yes, Grothendieck would put the nut in water, wait a few days, and it would open on its own. Bourgain would observe that your fingers alone need to be 10x as forceful to crack the nut, (cont’d)https://twitter.com/stevenstrogatz/status/1222628489414705152 …

2/ “As a teacher, [Courant] was good when he prepared, which was seldom” “Morrey understood lots of things, but he was hard to understand” “[At Courant] there was hardly any difference between pure and applied. There was just mathematics” “We could take turns playing Gelfand”

Suppose you have fixed power density, and the sun is of (variable) radius r. The energy flux at the surface - the thing frying you - scales as power density * volume / surface. That's proportional to the radius. The Sun is just a really, really big compost heap!

Heartbreaking anecdotes here. “More concerned with placating upset students and parents than backing up teachers, [administrators] would accept absurd excuses and tolerate unacceptable behavior.” Is it really this bad at so many places?https://twitter.com/NewLizardBrain/status/1220884784697806848 …
