For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You'd be surprised how far that gets you.

I know that the molecules in my body are traceable to phenomena in the cosmos. That makes me want to grab people on the street and say: ‘Have you HEARD THIS?

My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer.

When scientifically investigating the natural world, the only thing worse than a blind believer is a seeing denier.

When asked about which scientist he'd like to meet, Neil deGrasse Tyson said, "Isaac Newton. No question about it. The smartest person ever to walk the face of this earth. The man was connected to the universe in spooky ways. He discovered the laws of motion, the laws of gravity, the laws of optics. Then he turned 26.

The more I learn about the universe, the less convinced I am that there's any sort of benevolent force that has anything to do with it, at all.
