Goals:

Reading
- The class notes.
- Middleman, chapter 5.
Additional Readings:
In class we talked about the example of estimating the yield of a point explosion
through dimensional analysis, solved for early atom bomb tests by G.I. Taylor. A nice
discussion of his result is provided
here,
and a somewhat grainy reproduction of the actual images used in Taylor's study is
given here. It's a good
illustration of the power of dimensional analysis to solve complicated problems.
