There are photons that have been traveling for 30,000 years, and I'm... snatching them from this journey and planting them into my digital detector. And then I started feeling bad for the photon, and I said maybe it wanted to continue but I got in its way. But then I said, no, those are probably happier photons than the one that slammed into the mountainside that will go unanalyzed and will not contribute to the depth of our understanding of the universe.

We're an elective democracy where science and technology will define where the economically strong countries in the world will be. And science and technological literacy is important for security, as well.

What are you doing? Why are you concerning yourself with the meaning of meaning?

The persistent failures of controlled, double-blind experiments to support the claims of parapsychology suggest that what's going on is nonsense rather than sixth sense.

I try to write in a way where you care deeply what the next paragraph will be. I hear the rhythm of prose and that, to me, distinguishes great writing from ordinary writing. By the way, I don't even claim that I'm good. I claim that I value it.

Our entire universe emerged from a point smaller than a single atom. Space itself exploded in a cosmic fire, launching the expansion of the universe and giving birth to all the energy and all the matter we know today. I know that sounds crazy, but there’s strong observational evidence to support the Big Bang theory. And it includes the amount of helium in the cosmos and the glow of radio waves left over from the explosion.

Curiosity is a self-driven motivation to explore and to learn. Learning is like... you know, you have to take your medicine. And that is what it has become. And that's unfortunate.
