(BENG 100) The course covers basic concepts of biomedical engineering and their connection with the spectrum of human activity. It serves as an introduction to the fundamental science and engineering on which biomedical engineering is based. Case studies of drugs and medical products illustrate the product development-product testing cycle, patent protection, and FDA approval. It is designed for science and non-science majors. This course was recorded in Spring 2008.

This lecture series was life-changing. I was in college having no idea what I wanted to study and randomly stumbled upon this series of lectures on Biomedical Engineering. The topic that I found most interesting was tissue engineering. Now I'm at a top institution studying BME for my undergrad degree and loving every second of it. Had I not discovered this series of lectures I would have probably ended up with either a business degree or a biology degree.
Great sound - bad visuals
The lecturer has a great and simple way of explaining things. Unfortunately, the illustrations he is using throughout the lecture the whole time aren't visible for the viewer. This extremely limits the viewers understanding of the topics presented by the lecturer.
