The Science of Flight—Breaking the Sound Barrier and Beyond

September 15, 2017

During and just after World War II, the quest for ever faster fighter planes reached an apparent natural barrier—the speed of sound. Yet, on approaching this limit, aircraft became unstable and uncontrollable. In this full lecture, discover how a new approach to aircraft design solved the problem of compressibility and shock waves in this transonic region, paving the way for supersonic flight and paved the way to breaking the sound barrier.

Alternating Current vs. Direct Current—What’s The Difference?

June 21, 2017

Examine the nuances of alternating and direct currents, see how transformers use electromagnetic induction to transform voltage levels in AC circuits, and observe the role of diodes and capacitors in regulating current. See how the DC power supplies that charge our cell phones are constructed so that they convert alternating to direct current. […]
