Mathematician and astronomer August Ferdinand Möbius was born #OTD in 1790. 🧪 🔭
He is best known for devising a surface that not even the New York Times could find a way to both-sides.

This is a ward full of kids in iron lungs because they had polio. Vaccines saved future generations from this tragedy. RFKs determination to ban vaccines shakes me to the core because this picture from 1955 would once again become our reality.

At least 63 billionaires have now publicly endorsed Trump, hosted a fundraiser for him, or contributed to Trump aligned PACs.
Why are they rallying behind him? Tax cuts, mostly. But there's more.
The more Trump tears down democracy, the safer the oligarchy becomes.
Be warned.
