In the late 19th century, three brilliant inventors, Thomas Edison, Nikola Tesla and George Westinghouse, battled over which electricity system – direct current (DC) or alternating current – would power the world’s entry into the 20th century. The stakes were monumental. The battle epic. The “dirty tricks” down right dirty. And Eric Vedeler will take the “mystery” out of electricity.

Presented by Erik Vedeler, retired from NASA after a 26-year career at Langley Research Center as the head of the electromagnetics and sensors branch and prior to that as a microwave electromagnetic measurements researcher. He holds degrees in physics, computer science and math and a masters in electrical engineering. Erik demonstrates a passion unveiling the fun and mystery of electromagnetics.
