What's the deal with your nickname? How did you get it? If your nickname is self-explanatory, then tell everyone when you first started using the internet, and what was the first thing that made you say "wow, this isn't just a place for freaks after all?" Was it a website? Was it an email from a long-lost friend? Go on, spill it.
Captain Science was born back in High School when I had to do a demo in my science class. Since then my science geekyness has only increased. I now am a full time science geek working for the NYPD Crime Lab (no...its not just like on CSI)
