Organic as a dandelion seed, [the ship of our imagination] will carry us to worlds of dreams and worlds of facts

Not all birds can fly. What separates the flyers from the walkers is the ability to take off.

All colours are arbitrary.

The prediction I can make with the highest confidence is that the most amazing discoveries will be the ones we are not today wise enough to foresee.

I believe that part of what propels science is the thirst for wonder. It's a very powerful emotion. All children feel it. In a first grade classroom everybody feels it; in a twelfth grade classroom almost nobody feels it, or at least acknowledges it. Something happens between first and twelfth grade, and it's not just puberty. Not only do the schools and the media not teach much skepticism, there is also little encouragement of this stirring sense of wonder. Science and pseudoscience both arouse that feeling. Poor popularizations of science establish an ecological niche for pseudoscience.

Science is more than a body of knowledge. It's a way of thinking: a way of skeptically interrogating the universe.

We go about our daily lives understanding almost nothing of the world.
