You're going to want to listen to today's episode of Bulletproof Radio all the way through to the end because it's full of all kinds of information

about ways you can control your cellular biology and it's sort of non-stop. And at the end of the show, if you like what you hear about,

I'm going to tell you about a way that you can get red light therapy and a copy of headstrong as a gift. Even if you have the book,

it's always good to have an extra copy to give to your mom.

Bulletproof Radio, a state of high performance.

You're listening to Bulletproof Radio with Dave Asprey.

Today's cool fact of the day is that a tiny version of a physics toy is actually revealing a bunch of things about quantum

biology and quantum mechanics that we didn't understand. You've seen those suspended metal spheres dangling in a row where you pull in one and it hits the other one.

And those are hallmarks of Newton's cradle. It's kind of cool and sort of mesmerizing. And if you were alive in the 80s,

you probably saw those on the desks of executives. But scientists have recreated that idea on an atomic scale.

And they're using it to probe how quantum systems reach a balanced state, which is known as thermal equilibrium.

For instance, if you leave a mug of hot coffee on the counter, it'll gradually cool until it reaches thermal equilibrium,

which means it matches the temperature of the room. And that thermalization process is well understood on the scale of coffee cups,

but at the quantum level, no one really understands it. So the researchers studied how chaos introduction into a quantum Newton's cradle paved the way for

thermalization. And they replaced those big metal spheres with a row of chilled laser-trapped atoms that were kicked into motion with a laser.

And what they found was that for thermalization to happen, all the atoms have to be moving randomly, just like the jiggling molecules in your cup of coffee,

instead of moving in a regular back and forth pattern. To achieve randomness, they took advantage of the fact that certain atoms that use are magnetic.

So in addition to colliding with each other, the atoms tugged on one another, which why am I telling all this stuff?

Because, well, we have no idea what's going on. At the atomic level, we're just figuring this out. And they found that by using a magnet,

they could introduce that chaos. And the result is probably going to be important for designing ultra small devices and quantum computers.

And quantum computers are terribly important for us to be able to decode what's going on inside our own quantum biological systems,

like what's happening in yourselves. And this is a very cool fact of the day, because we're going to be talking about cellular biology and light specifically,
