Description
These interesting podcasts come from the University of Utah Department of Physics and Astronomy and describe how physics is utilized by the human body for every day activities like blood pressure, running vision, breathing, and hearing. They talk about how strokes are caused, blisters are formed ,how sun screens work and how diseases are caused. Listen as Richard ingebretsen MD, PhD helps us understand how physics helps to operate our bodies.
