Email Prof. Nimmo (fnimmo@es.ucsc.edu) 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 (2 ^{nd}
edition__), available in the bookstore. Not all parts of the course are
covered in detail in this book.

**Grading**:

40%
Weekly homeworks (due each *Wednesday 5pm*)

20% Midterm

40% Final

**Prerequisites**:

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.

**Plagiarism**:

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.
