Description
We return to two of our favorite topics, the red giant star Betelgeuse, and of course the Moon. Some clever historical detective work has revealed that Betelgeuse was not red, but yellow, two thousand years ago. This tells us how massive the star is and how far along it is in its evolution to a supernova. Closer to home, another clever bit of detective work gives a new history to ancient lunar craters by examining the Moon’s gravitational lumpiness. Cool!

Veridical Paradox
If you're tired of Zeno's Paradox, and have, in fact, successfully gone from point A to point B, try a veridical paradox. These head scratchers may hurt your brain, but they will also teach you how the world really works, because while they may be absurd, they are demonstrably true. Hilbert's Hotel with an infinite number of rooms all of which are occupied can indeed accommodate a countable infinity of additional guests. Stretch your brain and broaden your horizons with any of the many veridical paradoxes, including the Monty Hall Paradox, Eros Impossibility Theorem, and the Ugly Duckling Theorem. Veridical paradox, it's not tv, it's HBO (HBO).
