I've always been a bit of a space geek. I wrote an article years ago about the neutral buoyancy tank, which is this biblically sized pool where they train astronauts. And it was just the coolest thing.

Weightlessness was unbelievable. It's physical euphoria: Nothing about you has any weight. You don't realize that you are weighed down all the time by yourself, and your organs, and your head. Your arms weigh down your shoulders. In space simulation, you get to fly like Superman! You're hanging in the air! It's the coolest thing.

Science is you! It's your head, it's your dog, it's your iPhone - it's the world. How do you see that as boring? If it's boring, it's because you're learning it from a textbook.
