Description
(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.

Customer Reviews
bad speaker, doesn't really know anything
after about twenty or so minutes of stuttering and "ums" and "ahs" (extremely distracting), a student asked a question about how embryonic stem cells knew how to divide, and the teacher spent like ten minutes answering her with the same exact generalization about how they just divide. He really doesn't know and can't admit it. Instead he wastes times trying to explain whatever fourth grade biology text book would say. I also have to say he is a horrible speaker in general. I was so distracted with his stuttering, that I had to shut it off in twenty minutes.
