Khan Academy videos of interest

There are other ressources than Khan Academy out there, so I thought I’d start out with a few remarks related to those. I’m about to start a course on coursera which I signed up for a long time ago, but I’m actually reconsidering now because I may not be able to find the time. If you don’t know about the site, go have a look around. A friend of mine also linked to this collection of videos from MIT on Electricity and Magnetism – looks very interesting. Anyway, a few Khan Academy videos below:

Just how sensitive blood flow is to vessel radius is an aspect I’d never given much thought, even though this is not exactly the first time I’ve done work on fluid dynamics (there’s also a largish section on that at Khan Academy) or the cardiovascular system. For some reason this video really made that link much more obvious to me, and these dynamics make it easier in my mind to understand why even relatively small changes in blood vessel composition over time can actually impede blood flow quite significantly and turn out to have rather large physiological effects. Math far more often than not helps me to think more clearly about stuff.
