We would like to clear out every room over time, but asking guests to leave seems rude. Instead, every day we assign them new rooms using a monotone increasing function… Primitive Recursion and the Disappearing Guests Bevin Maultsby NC State University Hilbert’s Hotel is a well-known thought experiment which challenges...

We’ve seen that semialgebraic Teddy and semialgebraic Lambkin are both images of a four-dimensional ball. Could they be images of each other? The Teddy-Lambkin Theorem Ursula Whitcher Mathematical Reviews (AMS) My given name means bear—it’s the same root as the constellation Ursa Major—so growing up I had a huge collection... Read more
If we were working with low dosages and using the correlation between dosage and outcomes as our metric of assessing effectiveness, we might underestimate how well the drug is actually working...

Either math makes no sense at all, or integration by substitution is much deeper and more profound than we've given it credit for. I hope to convince you of the latter… Elliptic Functions, Doughnuts, and a Secret Integration Technique Anil Venkatesh Adelphi University Introduction Let's start with some pictures. What's...
