BRING SCIENCE HOME The First Cartoon: Make Your Own Thaumatrope! Now you see it--now you see more! Build this clever toy and see how some of the earliest cartoons were created. What will you animate?  Credit: George Retseck It’s probably difficult to imagine a time with no television, no movies and no cartoons. But believe it or not, those times weren’t so long ago! What did those kids do when they couldn't watch movies? One of the most popular toys during that time was a great-grandfather of the modern cartoon. This toy was called a “thaumatrope,” and in this activity you’re going to make (and test) your own thaumatrope to learn about how vision works!

Slow Stability Last year, the mathematician Elena Giorgi posted a 900-page proof that slowly rotating black holes are stable. Rachel Crowell writes about the proof and Giorgi's broader research interests for Science News. In their proof, Giorgi and her colleagues considered what would happen if a rotating black hole were struck by gravitational waves. Steve Nadis explained their proof by contradiction for Quanta last August.
