Sound: Crash Course Physics #18

We learn a lot about our surroundings thanks to sound. But... what is it exactly? Sound, that is. What is sound? And how does it travel? And what is this Doppler Effect that we've heard so much about? In this episode of Crash Course Physics, Shini goes over some of the basics (and some of the not so basics) of the Physics of Sound.

How the Brain Works Part 1 (UCLA)

These brief videos provide an introductory appreciation of how we learn skills and information, move, think, feel, speak and remember. They are brought to you by the UCLA Brain Research Institute and by Bruce H. Dobkin, MD, who directs the neurorehabilitation program in the Department of Neurology at UCLA. The videos especially aim to reach out to students in grade school to stir their interest, and to people with disabilities in walking, using an affected upper extremity, and loss of memory from neurological diseases such as stroke, brain trauma, tumors, multiple sclerosis, cerebral palsy, Parkinsons, and Alzheimers disease.
