EART 162 – PLANETARY INTERIORS
Spring 2010 Class Notes
All files are in Microsoft PowerPoint (.ppt) or Word (.doc) format unless otherwise indicated
Email Prof. Nimmo (firstname.lastname@example.org) if you have problems accessing them
Timing/Location: Tues/Thurs from 2:00 to 3:45 in E&MS D226
Course Goals: To provide an introduction into how we use remote-sensing observations and geophysical modeling to obtain a quantitative understanding of the structure and evolution of planetary interiors.
Course Outline: see below
Text: Turcotte and Schubert, Geodynamics (2nd edition), available in the bookstore. Not all parts of the course are covered in detail in this book.
40% Weekly homeworks (due each Wednesday 5pm)
One of: 110C, 111, Maths 22, Maths 23 A-B; and
One of: 113, Phys 6C, Phys 5C.
I am going to assume familiarity with ordinary differential equations. Some use will be made of vector calculus (div, grad, curl) and partial differential equations.
Collaboration on homework assignments is permitted and encouraged. But the work that you hand in must be your own i.e. if I ask you to reproduce your work on the board without your notes, you must be able to do so. If you are ever unsure about the appropriate level of collaboration, please ask.
If you use the textbook or other outside sources (such as web sites) then you must cite the source that you use.
