niels nielsen

physics enthusiast and electric bassist, recovering ex-engineer (there's a 12-step program for that but it's notoriously ineffective). Tries to answer questions on the stack exchange in order to help people and improve his game. Website full of weirdly cool stuff he's done at www.nielsenkillowatt.com
