Course Information

Description

Uses physics to analyze important technologies and real-world systems. Stresses estimation and “back of the envelope” calculations, as are commonly used by research physicists. New physical concepts are introduced as necessary. Example topics: energy production and storage, nuclear physics, nuclear power and weapons, health effects of radiation, risk analysis, airplanes, spy satellites, rockets, fluids, water waves, mechanical design and failure, global warming, and cosmology.  Emphasis is on developing physical intuition and the ability to do order-of-magnitude calculations.
