Classical Mechanics 0
In Chapter 4 (at the end of Section 4.7) I claimed that, for a system with one degree of freedom, positions of stable equilibrium "normally" correspond to minima of the potential energy U (q). Using Lagrangian mechanics, you can now prove this claim. (a) Consider a one-degree system of N particles wi

Probability and Statistical Inference 9
As a clue to the amount of organic waste in Lake Macatawa (see Example 7.1-4), a count was made of the number of bacteria colonies in 100 milliliters of water. The number of colonies, in hundreds, for \(n = 30\) samples of water from the east basin yielded \(\begin{array}{rrrrrrrrrr} 93 & 140 & 8 & 1
