Diffusion and Fick's Law
How do neurons send chemical signals to neighboring neurons? Why do you wear a jacket in the winter? Why do some animals have circulatory systems? These questions depend on random walks and diffusion. In this video, using a very simple model, you will learn the fundamental difference between a regular and a random walk, and be able to predict the consequences of that difference for biophysical systems. This video is part of the Probability and Statistics video series. Many events and phenomena are probabilistic. Engineers, designers, and architects often use probability distributions to predict system behavior. Hi, my name is Sanjoy Mahajan, and I'm a professor of Applied Science and Engineering at Olin College. Before watching this video, you should be familiar with moments of distributions and with concentration gradients. After watching this video, you will be able to: Describe the difference between regular and random walks. And, explain the structure of Fick'...
