Rated 5 out of 5 by from Outstanding course Dr. Ressler obviously put a lot of time and energy into preparing this course. The 3-D models he uses in the studio must have taken many hours to construct. His delivery is direct and personable, but succinct. His lectures on the Colosseum, the Pantheon, and the Baths of Caracalla are particularly informativde. I would reocmmend this course to anyone.

Rated 5 out of 5 by from Fascinating and accessible from start to finish I love this personable, enthusiastic, nerdy prof and the compelling way he brought engineering and history together. It's been almost 40 years since I dabbled in statics and dynamics, and Dr. Ressler's demonstrations, particularly the 3D models and animations, made it all very clear and logical. I can't recommend this course highly enough -- one of my favorite Great Courses so far.

Rated 5 out of 5 by from Excellent Course I am a software engineer, so I have some background in engineering, focused on computer hardware. Nevertheless, I learned quite a bit through this course, since I did not take Statics and Dynamics in school. I thoroughly enjoyed Dr. Ressler's teaching style and delivery, which is punctuated with humor and many physical demonstrations. Highly recommend this course to others, and have added a few of his other courses to my watchlist.
