That's awesome!". At the end of the day, though, we're physicists, and we need to ship some physics out the door. [0] http://guavaduck.com/laser/
I disagree. Take a military analogy - if you're not doing something "shippable" (ex: fighting), you are training to maintain or raise your potential for when you will have to get in action - or at least to maintain discipline. I'm not into physics, but if I had to place my bets between a team of physicists who loves to redo the world with the help of beers during long lunch hours, and a team of physicist who is into…
And adding in a quote I heard recently supposedly from a Navy SEAL
Under pressure you don't rise to the occassion, you sink
