Delta is a pretty special magazine about math, physics, and astronomy that’s been around for over 50 years. What makes it cool is that even though it’s meant for high schoolers, the content is actually quite advanced — even math grads might find it interesting. It’s kind of like the Russian Kvant. I’ve always thought it should be available in English, and now it is! Hopefully this won’t be a one-off. Definitely worth checking out.
