Back to Physics 434, 2012: Information Processing in Biology.
The main ideas we discussed in block one are:
- Many biological information processing systems are probabilistic -- we study properties of random variables -- uniform, Poisson, exponential, Gaussian
- Random walks and (on large scales) diffusion are particularly useful in modeling biological information processing -- and we studied their properties in different dimensions, in reaction-diffusion systems, etc.
- Noises can be modeled using different techniques, including the diffusion equation (Fokker-Planck), the master equation, the Langevin process
- Noises propagate, and these propagation properties are far from trivial.
