My heat transfer prof is a super smart, super nice older guy but he is sadly not a very good educator. So thanks Dr. Biddle I've used you to teach me fluids and now heat transfer. You've got such a no nonsense style to your teaching I love it! I recommend your videos to all my class mates. Also keep this camera person, he or she is on the ball!

Prof. Biddle knows all.

In my experience, professors from high ranking universities tend to not be very good educators nor do they care much. They care more about their research. I went to a Community college before I transferred to a "high ranking" engineering school (and by the way, I had very smart friends who went to lower ranking states schools because they were foreign students and could not afford the more expensive schools. So you also find high caliber students at state schools), and in my very personal experience, the professors at the community college were so much better at conveying the material and they cared more for the students. I don't know where this professor teaches and if it is a "high ranking" school or not but what I do know is that he seems like one of those professors that care about making a difference in his student's life. This institution is lucky to have such professors. Thanks to him I have relearned this material after 13 years out of school.

I've been lost in my heat transfer class as my professor's teaching style does not jive well with my learning style. This lecture series has been a life-saver. Such a concise, highly energetic educator. My hat off to you, sir.

To calculate sun's temperature, its easy to use \lambda_max*T = C_3 once we plot the radiation distribution instead of plotting curves at different temperature iteratively

Why is the formula for the heat radiation of a black body given by the integral of the whole graph from 0 to infinity? Shouldn't it be the integral from 0.1 micrometers to 100 micrometers (the wavelength range of heat radiation)?

I think the integral is from 0 to infinity because thermal radiation occurs only between 0.1 micrometers to 100 micrometers. Lower or higher wavelengths add thermal radiation close to zero so it makes no difference. But it's just a guess, but it would be possible to find out by comparison between the integrals of the function given by Planck's Law with two different boundaries (0..infinity and 0.1..100 micrometers)
