Show Notes
You've seen the headline: AI "solved" one of math's Millennium Prize problems. Thomas and Jenessa (here as a friend, not an expert) are joined by David Souther, a software engineer and LLM researcher, who's SO annoyed about it. Why did he answer Jenessa's text in all caps? And what's the deal with a rushed phone call between OpenAI and a math professor? Are you an expert in something and want to be on the show? Apply here!

We welcome back Dr. Eric Jaffe to help us understand a really cool, groundbreaking scientific discovery! Our brains are not one organ! Turns out your forebrain and your hindbrain might be two completely separate lineages that never actually came from each other, more like two kids in a trench coat than one continuous evolution. Why does that matter for ALS research? And how far back in evolution does the split actually go? Are you an expert in something and want to be on the show? Apply here!

How does AI use affect learning? You’d be surprised how much we already know.

Kids are weird, like really weird, but in a fun way? Dr. Jenessa Seymour is back to tell us about some classic child development paradigms that really need to be reevaluated. Depending on when you learned about these experiments, you were either taught that they were the gospel truth, with established ages where kids can and cannot pass these tests, and major consequences for late development, or maybe you heard that recent studies show it’s a bit more complicated. Still makes for some cute and funny demonstrations either way.

Dr. Tania Lombrozo, professor of psychology at Princeton University (affiliated with its philosophy and cognitive science departments), joins Thomas to discuss her forthcoming book Why We Ask Why: The Science of Explanation and the Human Drive to Understand. Why are humans so driven to explain things, but only some things? Why does understanding go beyond just being able to predict? And what happens when asking why makes you the social liability in the room? Are you an expert in something and want to be on the show? Apply here! Please support the show on Patreon!

David O'Brien, higher education policy scholar with the California Community Colleges System, is back to answer the question Thomas posed last time: why is college so expensive? They get into tuition vs. total cost of attendance, the dirty little secret of private university pricing, administrative bloat, the amenities arms race, and why the people loudest about college costs are likely well-off, but getting very little financial aid.
