A recent episode of the Nerdist podcast featured physicist Brian Cox, who hosts his own entertaining and enlightening podcast, The Infinite Monkey Cage.

I listened to most of this episode of the Nerdist while walking my dog last night. The podcast was a fascinating conversation between regular humans and a super smart scientist who has a knack for making complex concepts approachable for the rest of us.

It’s a great episode and made me consider possibilities about the nature of the universe that I hadn’t before. And Cox had this poetic comment more than an hour into it that I had to write down:

“I think the key to being a scientist is to delight in not knowing. It’s to stand on the edge of the known and face the unknown with curiosity and delight and not fear.” –Brian Cox

It’s the key to being not just a scientist, though, but a curious, open-minded human no matter your work. This embrace of not-knowing has been a theme in much of what I’ve read recently.

Courage is required, but delight and wonder and new possibilities are the reward for letting go of certainty.
