Will Pangea Form Again? The Next Supercontinent on Earth
Did you know that in about 200 million years, Earth is due for another supercontinent? What exactly that supercontinent will look like, though, depends on a lot of geological factors, and is harder to guess at than you might think!...

The Divergence Theorem
Green's Theorem gave us a way to calculate a line integral around a closed curve. Similarly, we have a way to calculate a surface integral for a closed surface. That's the Divergence Theorem. This is also known as Gauss's Theorem, and...
