Richard Feynman: Why Electricity Is Physically IMPOSSIBLE to Be What You Were Taught

Richard Feynman Why Electricity Is Physically IMPOSSIBLE to Be What You Were Taught I asked students at Caltech in 1964: “What is electricity?” And as usual, the entire class—some of the brightest minds we had selected—sat in silence, looking at me as though the question were a trap. The strange thing is that we have been living in the electrical era for nearly 150 years. Ever since alternating current was invented in 1888, since the first power stations lit up cities in 1882, since the incandescent light bulb appeared in 1879… electricity has become something far too familiar. You are surrounded by it: in the phone you’re charging, in the refrigerator running all night, in the electric car on the street, even in the Internet itself—born in 1969—the very thing you’re using to hear me right now. #richardfeynman #3iatlas #NASA #space #MichioKaku #spacenews #deepspace #sciencenews #spaceexploration #spacescience
