Episode 035 - Anne Hofmeister Shakes Up Earth Science

November 26, 2018

TSSM goes heavy: hard-hitting journalism from one of science's great controversialists, Anne Hofmeister. Intrigued? Disagree? Write me an email (giesting@alumni.nd.edu) or look her up at Washington University in St. Louis' EPS department website.

The times below are keyed to the start of the interview and ignore my opening (just over 2 min).

0:00 Introduction

1:00 Anne's background (sorry, this part Anne was talking so quietly that I can't seem to fix it with Audacity, but bear with us; we moved the microphone and figured some things out and it gets better)

2:00 Spectroscopy and heat transfer

3:00 Thermal conductivity experiments and their pitfalls

5:00 Criticism of the history of thermodynamics and heat transfer; identification of light and heat

6:00 Problems with equilibrium and elastic collisions in theories of thermodynamics

8:00 Criticism of phonon theory

10:00 Electron and vibrational transfer of heat decoupled; metals and heat transfer

13:00 Garnet

14:00 Earth's interior: convection, the Rayleigh number

15:00 Viscosity

16:00 The Earth's mantle: nearly all solid

17:00 Plate tectonics without mantle convection

18:00 An even more radical idea: heat is being trapped inside the solid Earth

19:00 [there was a distortion I had to cut]

20:00 Implications: heat generation is in the crust (this part is widely known!)

21:00 Implications: the core is melting, not solidifying?

22:00 The geodynamo and magnetic field

23:00 The core: buffered at the temperature of melting high pressure iron

24:00 Magnetic modes diagram for the planets: spin and magnetic field
