Rated 2 out of 5 by from Well Prepared But Annoying Delivery It’s obvious that he spent a lot of time preparing the material. Unfortunately he had to talk very fast to get everything in the 36 hour format. Also, it was very to see him constantly looking at his notes. I got the feeling that he was checking them to make sure that he was getting everything covered in the compressed time frame. Finally, in several places he talked about events that happened 10-15 years ago. I wonder what this course would look like if it was recorded more recently.

Rated 5 out of 5 by from very good I think this professor is excellent! I though Physics was very hard to understand, but he made it far easier for me to understand. And this course covers a lot of knowledge in Physics. I am glad that I found it.

Rated 5 out of 5 by from A Fascinating Course Very Well Presented All credit to Professor Wolfson for providing an excellent series of lectures that are interesting and informative without being too heavy for a non scientific person to understand. Starting to show it's age now (2004) but the majority of the content is still relevant. I thought that overall the course was excellent and very well presented.

Rated 5 out of 5 by from Absolutely fantastic course!!! Brings physics into every day life and shows you how physics works in almost everything we do in actual life. Professor clearly demonstrates the everyday way physics affects every aspect of daily activities. Highly recommend this excellent course!!

Rated 5 out of 5 by from wolfs is an amazing lecturer just the module on computers makes this course worth the time and expense. Unlike a few other physics courses, this one is easily understandable and i still paraphrase parts of it 8 years later

Why does a curveball curve? Why does ice float? How do CDs and DVDs work? Why don't your legs break when you jump off a chair? What keeps a moving bicycle from falling over? These questions involve physical principles that relate not only to interesting aspects of our daily lives, but also explain fundamental features of reality. In this DVD-only course, filled with hands-on demonstrations, you explore the physics of everyday events and end up with a deeper understanding of the universe.


Richard Wolfson

Physics explains the workings of the universe at the deepest level, the everyday natural phenomena that are all around us, and the technologies that enable modern society. It's an essential liberal art.


Middlebury College

Dr. Richard Wolfson is the Benjamin F. Wissler Professor of Physics at Middlebury College, where he also teaches Climate Change in Middlebury's Environmental Studies Program. He completed his undergraduate work at MIT and Swarthmore College, graduating from Swarthmore with a double major in Physics and Philosophy. He holds a master's degree in Environmental Studies from the University of Michigan and a Ph.D. in Physics from Dartmouth.

Professor Wolfson's published work encompasses diverse fields such as medical physics, plasma physics, solar energy engineering, electronic circuit design, observational astronomy, theoretical astrophysics, nuclear issues, and climate change. His current research involves the eruptive behavior of the sun's outer atmosphere, or corona, as well as terrestrial climate change and the sun-Earth connection.

Professor Wolfson is the author of several books, including the college textbooks Physics for Scientists and Engineers, Essential University Physics,and Energy, Environment, and Climate. He is also an interpreter of science for the nonspecialist, a contributor to Scientific American, and author of the books Nuclear Choices: A Citizen's Guide to Nuclear Technology and Simply Einstein: Relativity Demystified.
