Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

People have suspected that Earth rotates for thousands of years, but how did we first prove it?

What is a Neutrino?
