For most people, the word "calculus" triggers a kind of academic vertigo. It marks the spot where the intuitive world of numbers hardens into a thicket of dry, mechanical symbols — a gatekeeper meant to be endured rather than a window meant to be looked through. We remember it as a series of hurdles. Steven Strogatz, a professor of applied mathematics at Cornell, remembers it as an epic. Strogatz is what you might call a mathematics mensch . Despite his world-class credentials, he still describes himself as the "weakest math major" of his Princeton years, watching classmates solve problems at a speed he couldn't match. That humility is what makes him such an effective translator of the subject. Whether he's walking the hills of Ithaca dictating chapters to his dog, Murray, or trading ideas on the Into the Impossible podcast, Strogatz treats mathematics as a matter of human history and feeling, not formula. For him, calculus isn't a textbook subject. I...
The data show a labour market bruised by many things. AI, so far, is a bit player BAD NEWS travels fast, and few stories travel faster these days than the one about robots coming for the cubicle. Layoffs at Coinbase, Meta and Cisco are cited as proof that a white-collar reckoning has begun. Yet a look at the actual figures tells a duller, more reassuring story: America's aggregate labour market shows scant sign of an AI-driven collapse. Unemployment among occupations most exposed to artificial intelligence is, if anything, lower than among those least exposed. Nor is there any sign of a mass migration from AI-threatened desk jobs to supposedly safer manual ones — the kind of shift one would expect if the robots really were coming. None of this means AI is harmless to workers. It means the disruption, if it is coming, has not yet shown up in the statistics that economists watch most closely. Slow-moving technology, fast-moving fears Erika McEntarfer, who ran the Bureau of ...
