Are the Fundamental Constants Changing?
The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

Bowled Over
So, variables. There are lots of them when trying to test an idea. The trick is to isolate one variable at a time to get reliable results every time. But, how do we do that? In this episode of Crash Course Kids, Sabrina shows us how to...
