    I'm floored! Dr. Soares has explained a lot of VERY abstract concepts in a VERY practical, VERY easy to understand way. This 20 minute video succeeded in elucidating many of my questions from HOURS of watching videos given by droning physics professors scribbling formulas (for the 10,000th time). Of course, the formulas are indispensable but there needs to be a connection between the math and the physical. Thank you!

    This video was beyond helpful. I am required to do a lot of rheology in my new R&D job, and this video really helped me brush up on some of the underlying concepts. Well done, and thanks so much for putting this together!

    Excellent video. There are clear distinctions to understanding the moduli... the concepts apply similarly across different types of shear... and without these distinctions, it is easy to lose track of what symbols mean what and where. Cheers
