Rated 5 out of 5 by from Adds to our Travel Pleasure We love to travel and have seen many of the discussed structures but this course will add to our awareness of the structures and their history. Excellent presentation with models, one does not need to be an Engineer or Mathmatician, although it probably helps.

Rated 5 out of 5 by from Wonderful Stephen Ressler is my absolute favorite GC instructor. I own all 4 of his courses and hope that he does more. This course is kind of heavy on the math/algebra but his wonderful models make complicated engineering concepts understandable. Course has many excellent photos of unique and beautiful structures along with lots of computer generated presentations

Rated 5 out of 5 by from Captivating Course The Greatest Structures course is the eighth (maybe ninth) TGC lecture series that I have purchased. I have focused mainly on cultural and historical lectures. They have all been informative and I am hooked on them. Some of the courses are a bit distracting in the pacing back-and-forth method of presentation, but nothing fatal to the course. I purchased the Greatest Structures (outside my usual focus) based on the rave reviews. The Greatest Structures course is terrific! I am not an engineer or architect so the basic information and presentation was perfect for me. Prof. Ressler's presentation is smooth, relaxed, and folksy. My understanding of design and engineering expanded with every course. After each lecture, I drove my wife crazy trying to tell her about what I had learned. I cannot drive down the street or watch Rick Steves' travel lectures without seeing buildings, bridges, and towers in a new light. I loaned my Great Structures DVD's to my neighbor who has now watched them twice. Great Structures has been the best of all the courses so far.

Rated 5 out of 5 by from It's Truly a "Great Course" I based my purchase on prior reviews and I am very much interested in this subject. The instructor seems to be a really nice guy who is passionate and well organized. He explains things in such a way that it's very understandable. I took statics over 20 years ago and I struggled and ended up changing majors. It's nice to come back this type of course because I really enjoy civil and environmental engineering. It's never too late to learn about structures and it still might be very useful to my life.

Rated 5 out of 5 by from Great Photos, Graphics and Physical Models Of the 54 courses I have viewed, "Understanding the World's Greatest Structures..." was the best, so far. Professor Ressler is an excellent presenter and uses Physical Models, Graphics and many photographs as examples of how structures work. There are only a few formulas he uses, which makes the presentations go quickly and not bogged down with minutia. He uses many photographs as examples of the various styles of structures, both bridges and towers, which he explains separately. He uses graphics to further show how these photographed structures behave, the way they were designed. The physical models, mostly made of wood, were very well crafted to show the forces exerted against the various parts of the models. Professor Ressler's presentations were so entertaining that I felt like the lessons were over before they began. This is in conparison to some lessons, by other presenters, that you wish they were over, sooner. Although I have a technical background, I enjoyed how Professor Ressler presented his ideas in a casual, but, complete and accurate way. Whether you are technically savvy or just interested in static-based physics, you will enjoy this course. I highly recommend "Understnding the World's Greatest Structures: Science and Innovation from Antiquity to Modernity".

Rated 4 out of 5 by from Very Well Produced and Informative This course lives up to the standards of excellence that I enjoyed in a previous course by Prof. Ressler – Everyday Engineering. If you enjoy practical engineering, take these two courses. In this course, Dr. Ressler explains the world’s greatest structures, using civil engineering and architecture. He is an excellent speaker who uses diagrams, illustrations, pictures, and impressive models to great effect. The models are hand-built and a great teaching tool. As a retired engineer, I’m in awe of his range of knowledge. When you read his Course Guidebook, you’ll be impressed just with the Appendix. It contains easy to understand solutions to many problems. There are also impressive tables that list attributes of the important structures throughout past and modern history There are many positives that easily offset my one negative comment. My main criticism is that his pace is fast and sometimes hard to follow. I’m ashamed to admit it, but I often became sleepy despite how good the course is. I guess I’m just getting old? If you like science and engineering, take this course – you’ll enjoy it.
