We are teaching and traveling with the start of the semester. Since John has no solid cell phone signal at a conference in New Hampshire and Shannon is swimming in lecturing, we wanted to share one of our favorite interviews from this year!

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.

Classes start next week - it’s time to evaluate what we did over the summer. How did our summer manifestos work out and what are we going to accomplish this fall?

John’s Fall Goals

  • Figure out my future job
  • Finish up a couple of instrumentation projects
  • Assemble my dissertation
  • Don’t let this class kill me

Shannon’s Fall Goals

  • Look for my replacement for Evernote
  • Actually look at my to-do better next time list for classes
  • Read all the literature!
  • Submit a manuscript
  • Have fun with my new class…geology of extreme climates

Limericks

We are setting up a time to record with our judge, it may be a week or two, but hang in there. If you want to send in an audio recording of you performing your limerick, that would be awesome. Don’t forget - we have STICKERS!

This week we address a listener show request from Mike about the Driftless region and address the phenomena of Pokemon Go. Can it improve our spatial reasoning?

Having just got back from vacationing near a river, Shannon’s mind is wondering (and wandering!) about dams and their impacts, both good and bad. People use dams for electricity, recreation, flood control, and a myriad of other things. Let’s take a look at some huge dams and what they do to both communities and rivers.

Why build dams at all?

  • Water supply
  • Irrigation and flood control
  • Power supply
  • Recreation

Hydroelectric Power

  • Hoover dam generates 4.5 billion kw-hr per year, serving 8 million people in AZ, southern CA and NV
  • Itaipu dam, on the border of Brazil and Paraguay, dams the Parana River, the 7th largest in the world.
  • Penstock
