almost insanely wrong in hindsight about some things and are brilliant visionaries in other ways.

And one figure that I learned about was Max von Pettenkofer, who really did the research behind those carbon dioxide meters.

He figured out in the mid-1800s that you could figure out the ventilation in a room by looking at the carbon dioxide.

We call it the Pettenkofer number, like how much CO2 is in the room.

Visionary guy.

Also, totally refused to believe in the germ theory of disease.

Amazing.

He even tried to convince people that cholera was airborne, and he did it.

He took a vial.

He was an old man.

He took a vial full of Vibrio cholerae, the bacteria that cause cholera.

rank it down to prove his point he didn't feel well afterwards but he survived and he said that's my proof so this history of science is not the simple story that we imagined it to be yeah well congratulations this was a tour de force you had to put in a lot of work to pull this all together and you're enlightening us about air like never before so thanks so much for joining Carl it was a real pleasure thanks for having me

The building blocks for our DNA... They're all right-handed. They could be left-handed, but they're not. And that's just a rule across all of life.

Now, if you want to make mirror insulin, there's no cellular factory around that you can use to make those molecules. You have to make them by hand, basically.
