Rated 5 out of 5 by from Clear and Comprehensive Lectures Prof. Wolfson tackles tough subjects and make physics easier to understand. He goes at a rapid pace but uses demonstrations that really help. The lectures have been thought out well and add a little fun to the understanding. This is not an audio course as the demonstrations are important to understand the concepts he is teaching.

Rated 3 out of 5 by from Just 'so-so' The professor's presentation is awful in my view : way too rushed - like his main focus is to get thru the material in a certain time frame rather than make it comprehensible. The pdf guidebook is a saving grace, and I'd suggest reading the chapters prior to watching the presentations.

Rated 4 out of 5 by from Physics in Your Life A little dated, but the principles of basic physics don't really change. One of the 'new' technologies mentioned in the first two lectures was DVD technology. The teacher is very fast-talking so it's a little hard to keep up, but he says that he will mention some of the concepts in more detail in the future modules in the course.

Rated 5 out of 5 by from Awesome presentation .... I wish I would have had this presented to me at high school before taking all the advanced classes in physics, thermo, etc. in college... great job of explaining the basic nuts and bolts!!! Professor Wolfson does an outstanding job of making the material understandable and alive with his presentation and prop usage. GREAT job!!!!

Rated 5 out of 5 by from Physics made simple Richard Wolfson explains how the laws of physics impact everything you do, use, and see in your everyday life, even your body. He gives many examples and demonstrations of the physic principle he is describing, making it easy to understand, even for those who don't have knowledge of physics. Great course.
