Back to Physics 380, 2011: Information Processing in Biology.

Please turn on the assignment either as a PDF file to me by email, or as a printout/writeup to my mailbox in physics. Detailed derivations (with explanations) and calculations must be present for the problems for full credit.

1. Let's suppose a particle starts at $x=0$ and diffuses with a diffusion coefficient D and no drift. Calculate the distribution of particle locations at time $t$.
2. How does the above distribution change if there is drift v?
