Learning Radiometry, Photometry, Optics, Thermodynamics, Fluid Mechanics(Statics & Dynamics) with great resources. I'm looking for resources for understanding the topics above. I prefer video tutorials as opposed to books but I couldn't find any video resources on Photometry and Radiometry (I guess I'll have to settle for books). As for Optics, I plan on studying the series on Khan Academy/iLectureOnline (unless you guys suggest something else). I tend to prefer video tutorials because I'm quite short on time, they usually give me enough insight without spending too much time on it, then I simply augment what I lack with books. In general I'm looking for resources that would help me understand the physics behind Radiance(the command line program). Esp. concepts and terminologies such as Lighting, Daylighting, Artificial Lighting, Sky types, Illuminance, Luminance, Radiation, Brightness, Luminosity, Flux, etc. including their relationship to material properties (e.g. transmissivity, transmittance, reflectance, specularity, etc.) If you're not familiar what Radiance (https://www.radiance-online.org ) is, it's simply a simulation program for simulating things such as Luminance, Illuminance, etc. for buildings mostly. It doesn't matter though if you're not familiar with Radiance since I've already found some resources for learning the program itself that now I'm more interested in looking for resources to understand the phycsi behind it. As for Thermodynamics and Fluids, I can see that Khan Academy and some other resources have them but they're not Calculus-based. I've already studied Thermodynamics, but it wasn't Calc-based. I'm looking to deepen my understanding of the two fields through good resources, again preferably calc-based and videos. If no videos exist, then any excellent resource would suffice. I'm also assuming the Thermodynamics course @ MITOpenCourseWare is not calc-based. I have a background in multivariable calculus so it might be easier for me to understand these topics in terms of Math. I do have an idea of these topics, but they're descriptive for the most part, not concrete/mathematical. But of course it'd be better if the resources are both descriptive and mathematical. Let me know if I've missed some topics that would be crucial for understanding Radiance. Thanks!
