Lecture 1 - Random walks - I What's Important: course logistics discrete random walks Text : Reif Demo : strings, ball falling down peg board Logistics Text: Statistical and Thermal Physics by Reif To be covered: most material up to Chap. 12 Grading: 15% for 10 assignments 25% for midterm exam 60% for final exam Random Walk in one dimension For the first several lectures, we discuss the random walk problem, which has widespread applicability in physics, chemistry and biology. For example diffusion configurations of polymers, including proteins and DNA non-interacting spins in a magnetic field ↓↑↓↓↑↑↓↓↑↓↓↓↓↑↑↑ In one or two dimensions, the problem is often compared to the random motion of a drunk near a lamp-post: this motion can still be random, even if the probabilities are unequal
