“I remember chatting with a doctor who said, unless you strapped the helmet to a player’s shoulders so that your head couldn’t move around on your neck, the helmet really can’t do all that much to prevent a concussion,” says Kathleen Bachynski , an associate professor of public health at Muhlenberg College. “I do think you can tweak design around the edges, but I think you’re up against the law of physics.”

Each month, the BPP tracks millions of prices, with sources spanning e-commerce sites, credit- and debit-card transactions, retail food surveys, regulatory filings, pharmacy transactions and corporate datasets. The goal is to measure prices in a way that is as close as possible to the approach used by BLS, but adapted to alternative sources.
We construct price indexes at a deeper level of granularity than the CPI, breaking them down by criteria like product, geography and brand.

Almost half (44%) of our tested claims are now expired in today’s models. Another 34% have weakened significantly, 16% persist, and 6% have strengthened relative to the original claim. Persistence varies by topic. Five of nine reasoning claims and six of eleven sycophancy-and-deception claims are classified as expired. Three of ten claims about models as judges, reviewers, and raters persist or strengthen.

Cusack succeeds in delighting his readers with Momo, too, but only if traditional definition of “delight” is expanded to include hard-earned enlightenment. The story piles on enough facts, half-facts, and non-facts to create cognitive dissonance, which only then leads to something delightful: the moment when the reader asks where the truth is. Or more precisely, how much they’re being lied to.

One might ask if at some point pure mathematics will somehow be “finished”. And to this we can definitively answer that it will not. Computational irreducibility ensures that there will always be an infinite sequence of mathematical facts—and surprises—to be discovered. And there will also be an infinite number of pockets of computational reducibility, representing new mathematical concepts and structures.
Many beautiful thoughts here in Stephen Wolfram's latest essay on AI's role in pure mathematics.
