In the 2013 interview by TED founder Chris Anderson, Elon Musk must have inspired countless people to pursue a career in science, especially physics when asked about the secret to his innovative projects. I've been reading Musk's biography by Ashlee Vance. It is an inspirational read. So far, the take home message for me has been, Musk surrounds himself with people who are really smart and he is a serial workaholic. On a more technical note, his companies Tesla and SpaceX have been using 3D printing technology to produce lighter, stronger and cheaper components for cars and rockets.
