Preet Bharara 0:41
What happens when political appointees push charges that career prosecutors don't support?
Matthew Schmidt 0:46
There is an element to this administration that wants to simply shout down reality. And I think shouting down reality and shouting down justice, shouting down fairness, should be a deeply concerning thing to all Americans.
Preet Bharara 0:59
I'm Preet Bharara. And this week, longtime GOJ reporter Devlin Barrett joins me to discuss his new book, The Department of Revenge, How Trump Took Control of American Justice. The episode is out now. Search and follow Stay Tuned with Preet wherever you get your podcasts.
Meredith Hodnot 1:29
And that's us. Noam and Meredith. Jazz hands. Jazzing it up. All right. So do you remember the great archive scramble of 2025? When we had to save all our show ideas?
Noam Hassenfeld 1:48
Yeah, yeah. All of our, like, oldest messages we'd sent each other on the team were going to disappear. Yeah. Show ideas, books we'd found, our favorite science articles.
Exactly.
Noam Hassenfeld 2:01
Then you scrolled through that whole thing, right? Like, years and years of messages, and you put them into this ridiculously huge Google Doc?
Meredith Hodnot 2:09
It wasn't the most graceful solution, but we saved it. I was actually just scrolling through this the other day, and... There's so much good stuff in there, way more than we could ever make into episodes. So it got me thinking that we should just shout out some of this great work.
Noam Hassenfeld 2:28
Oh, yeah.
Meredith Hodnot 2:29
I mean, yeah, some of our favorite science writers, our favorite articles and point listeners to where they can find them.
Noam Hassenfeld 2:36
That sounds awesome. Let's do it.
Meredith Hodnot 2:37
Yeah. So today, for you, Noam, I picked an article by Charlie Wood in Quanta magazine.
Noam Hassenfeld 2:46
Ooh, love Quanta.
Meredith Hodnot 2:47
And this is just like an example of some of my favorite science writing. The kind of writing that takes something everyday, takes something ordinary, and just makes it extraordinary.
Noam Hassenfeld 2:59
Yeah.
Meredith Hodnot 2:59
So his article is called, What Causes Lightning? The answer keeps getting more interesting.
Yeah.
Noam Hassenfeld 3:06
I don't know if lightning is ordinary.
Meredith Hodnot 3:08
It's true. It's a pretty, it's of the like everyday phenomena. It is pretty extraordinary.
Noam Hassenfeld 3:14
Yes. It is already, let's be fair to lightning. It's pretty cool.
Meredith Hodnot 3:19
I love watching thunderstorms.
Noam Hassenfeld 3:21
Yeah.
Meredith Hodnot 3:22
So believe me, already a lightning fan.
Noam Hassenfeld 3:24
Okay.
Meredith Hodnot 3:25
But this article blew my mind. And it's because we know what lightning is, but we don't know what triggers it.
Noam Hassenfeld 3:33
Classic unexplainable.
Meredith Hodnot 3:34
Classic unexplainable frame there.
Noam Hassenfeld 3:37
Yeah. What actually is lightning? I feel like you're saying we know what lightning is.
Meredith Hodnot 3:42
Science knows what lightning is.
Noam Hassenfeld 3:44
I don't know if I would be able to tell you what lightning is other than electricity.
Meredith Hodnot 3:49
It is electricity. It's a form of static electricity, so the same as rubbing on a balloon and then shocking yourself, but just at a wildly bigger scale. And in this case, the static electricity comes from ice and water droplets and hail inside the giant thundercloud itself that, through all the turbulence and updrafts, is rubbing against each other and building up this giant electric charge.
Noam Hassenfeld 4:17
Uh-oh. And that's lightning.
Meredith Hodnot 4:19
And that's lightning. But there's a problem. There's just not enough energy in the cloud. Like, there needs to be enough electric force to literally, like, break apart the molecules of the air and release, as Charlie puts it, like an avalanche of electrons that crash across the sky.
Noam Hassenfeld 4:37
Oh, okay.
Meredith Hodnot 4:38
There's this threshold that we need to get over, and there's just not enough energy in clouds to get over that threshold.
Noam Hassenfeld 4:45
Wait, is it not Zeus?
Yeah.
Meredith Hodnot 4:48
It is perhaps not Zeus. Okay. But it might be cooler.
Noam Hassenfeld 4:53
Okay.
Meredith Hodnot 4:55
Apparently there's a whole generation of scientists who are using tools designed to look at things like solar flares and deep space explosions.
