"Maybe you can afford to wait. Maybe for you there’s a tomorrow. Maybe for you there’s one thousand tomorrows, or three thousand, or ten, so much time you can bathe in it, roll around it, let it slide like coins through your fingers. So much time you can waste it. But for some of us there’s only today. And the truth is, you never really know."

Science is not just about theory; it's about making things that work in the real world.
