From The New York Times: “ON a recent Monday night, a gaggle of 20-somethings crammed into a former Curves fitness center along the industrial edge of Carroll Gardens in Brooklyn. The storefront gym had been carved into two classrooms. In one, a rugged blond man, Brandon LeNoir, was teaching a class called “Let There Be Light.” A dozen students, huddled at long butcher-block tables littered with wires and scissors, learned how to make a simple lamp. “Don’t worry about neutral and live wires,” said Mr. LeNoir, 34, an interior designer by day. “It doesn’t matter for us.”…It was just another school night at the Brooklyn Brainery, a hipster schoolhouse started by a pair of underemployed polymaths, where students can learn abstruse subjects like the secret lives of bacteria, taught by teachers with few teaching credentials. Tuition is $5 to $30, enrollment takes place online and PayPal is accepted.”
