Only costs $150Bn (25% USA yrly military budget) to deploy 2000Km of digitally controllable micron-thick solar sunshades which would allow us to variably adjust the temperature of the Earth. Blocks up to 2% of sunlight, controllable instantly from Earth (by rotating shades).

Probably the craziest thing about all of this for me is that my piece on the book has gotten >250k views by now and still not a single neuroscientist or sleep scientist commented meaningfully on the merits of my accusations. Only Andrew Gelman (a statistician) picked them up.

@Health_Affairs @ml_barnett @AnupamBJena @yhgrad @athenahealth We compared patients treated before vs. after someone with the flu. Patients treated after were more likely to revisit in the next two weeks…with the flu.

In a coin toss, what's the chance of getting two heads in a row?
Someone had the brilliant idea of asking politicians.
77% of UK Labour MPs didn't know, only 23% did.
It was about half and half with Conservatives.

Considering a donation to Wikipedia? They sure need your money, how else can they keep doubling their budget every three years? But you could also donate to SciHub instead.

A thing that helped me leave academia was a “normal” review proc where the editor maintained that if “novelty was compromised” before acceptance then they would reject it, and then delayed accept upon pos reviews by months for clerical reasons. Imagine if my future was tied to it https://t.co/3aPx7MdREF
