Episode 57 – “You go to a cave and do math problems”

This week we’re going underground…to caves that is. We review the basics of how caves form, some unique features, and a lot of fun vocabulary. We also talk about the latest and greatest scientific discovery!

Fun Paper Friday

This week we learn about one of the most exciting physics discoveries in modern physics – the measurement of gravitational waves.

Episode 56 – “A lot people would like to think they’ve got a lunar meteorite” Brad Jolliff

This week a special guest takes us to the moon by talking about lunar rocks and meteorites! The moon turns out to be a fascinating place, but probably won’t break up like in Seveneves.

Episode 55 – “Every time you clip your fingernails” Plate Tectonics

Why do mountains form, earthquakes happen, and volcanoes form where they do? The answer is plate tectonics. This week we explore the history of being wrong about how the Earth works.

Episode 54 – “We use statistics”

We’ve already talked a little bit about the Earth’s magnetic field, but where does that fall in terms of geoscience? Lots of physicists look at the magnetic field, but so do geologists. Not just our current field, but the ancient magnetic field, which is called paleomagnetism.
