"Short Course on Impact Cratering" Professor H. J. Melosh

Dear all

This is an announcement of course (3 times) hosted by Fluid Mechanics Unit.

Title: Short course on impact cratering
Speaker: Professor H. J. Melosh,
        (Distinguished Professor of Earth, Atmospheric and Planetary Science at Purdue University USA.)

This short course consists of three lectures:

1.  Introduction to impact cratering:  History of study and implications for science

2.  Shock waves and Crater Mechanics:  The three stages of impact cratering

3.  Numerical modeling of impact craters

These three lectures will offer a brief introduction to the process of impact cratering, starting from a historical perspective that will introduce why impact craters are important to us today.  A second lecture will focus on basic ideas of shock waves, their interaction with geologic materials, and the underling mechanics of the impact process.  I will also discuss how to recognize whether or not a circular structure on Earth was caused by impact (the vast majority are not, despite numerous claims by overenthusiastic geologists!).  The course will wrap up with a description of how impacts are modeled numerically and the basic requirements of numerical models explained.  I will also introduce the class to iSALE, currently the premier tool for modeling impact processes.

Schedule:

Lecture 1:  January 18^th (Wed), 11:00am-12:30pm, @B700

Lecture 2:  January 18^th (Wed), 4:00pm-5:30pm, @B700

Lecture 3:  January 20^th (Fri), 11:00am-12:30pm, @C210
