Astrophysicist Jeff Hester on The Poetry of Science, Hot Yoga, Bertrand Russell, and His Upcoming Visit to Changing Hands

After dabbling in guest lectures, textbook authoring, and commercial acting for Irish hard ciders, Hester returns to the public eye with Adventuresome Minds, a science conversation series in Tempe. 

After two successful nights at Studio Vino, the event arrives at Changing Hands Bookstore on April 11 with "From Big Bang to Big Brains," a program which Hester describes as equal parts physics and philosophy.

Here are just a few thoughts Hester explained when he sat down with Jackalope Ranch last week:

Why Conversation > Lecture for Learning Physics

"It's kind of like the difference between going and hearing a symphony or orchestra and going to a rock concert. Symphonies are fine, but what makes the rock concert fun, what makes it memorable, is that it's participatory. And people's brains do better when they're active. It's just more fun to be part of a conversation.

"[Adventuresome Minds] is bridging that gap. [...] You go see a science fiction, and I like science fiction movies too, [but] the reality of what's out there, the mind-blowing, head-spinning, philosophically daunting reality of what's really out there is accessible. It doesn't have to hide behind words. And what makes it fascinating is that it is accessible, that it is everyday, that it is related to our experiences."

On the Art of Science

"The poet says, 'You are stardust,' but that's not [just] poetry. That's literal truth. We're living in a universe that began in an event, The Big Bang, which had no cause. What does that mean? To say that the universe itself has no cause? That's a fascinating question to try to wrap your head around.

"If I tell you that my job is to look around me and look for patterns in the world that I think are meaningful and then to find a way to express those so that other people can see the meaning in them as well, am I scientist or am I an artist? Fundamentally, there is no difference...

"Internally ... science and art are the same damn thing. And one of the things I care about deeply is conveying that vision, giving people an understanding, letting them see those ideas about the universe [...and] showing them the beauty in that, the elegance."

On the Limitations of Physics, Even Today

"Isn't there a contradiction between, on the one hand, saying we know a tremendous amount, and on the other hand, acknowledging that there's a lot that we don't know?"

"Once you say you're certain, the game's over. You don't know a damn thing. It's by confronting your ideas, challenging them, looking for their weaknesses, being open to new evidence that might come along and make you reassess, it's by doing that that you build reliable knowledge of the world.

"Think about it. If there's an idea that you really care about, that really matters to you, that you really want to be true, do you want to work to show that it's right, or do you want to challenge it to see if it can withstand the challenge? I hope the answer is that you challenge it. I would prefer not to hang my hat on an idea that can't withstand that kind of scrutiny."
