I'm a first year student taking undergrad course in Aeronautical Engineering. Truly speaking, this interactive site helped me a lot, that I totally got addicted to it. In fact, most of my reasoning and intuition in physics was brought by my lovely fellow members here. Mostly, I'll be around doing this editing, reviewing, poking into random questions, etc. I do answer questions too which sometimes may turn wrong ;-)

To those who're interested in space-travel, don't miss this proposal...
