Let's talk about the space-tampon story. OK, so this is a story confirmed by Sally Ride and Kathy Sullivan, where a male engineer asks if 100 tampons is good for one week, and she politely tells him he can go a lot lower. Very often repeated, and true so far as it goes. BUT

My little Jacob Wohl story: August 2016, we're sitting around the trading turrets at my office on a bored to tears slow day. Our receptionist said someone was here for his 2pm appointment. None of us had an appointment on schedule. Who is it? we ask? Some guy named Jacob Wohl 1/

Jacob Wohl, for those out of loop, gained quite a bit of notoriety for becoming the youngest guy to ever get himself barred for life from the financial industry. Now he's waiting in our lobby to pitch something. We're a large merchant bank. 2/

Send him in, we said. In walks young Jacob asking to be seeded with $25mm to start a new hedge fund in exchange for an ownership stake in it. Oh, & he needs an office. And a Bloomberg station. And needs to borrow staff until he can hire some guys. And he needs a leased car... 3/

And he needs an answer today. Right now. Because there's a competing offer from Izzy Englander's firm Millenium (we know those guys well). We fight the urge to literally start laughing, but do ask him...hey, you the same guy who got banned by regulators? He didn't even flinch 4/

He went on about that being untrue & handed over a letter he said was from his lawyer who had confirmed he was not barred, had been vindicated but it 'just wasn't in the system yet at the SEC, CFTC'...whatever that means. 5/

Remember: Just because an idea is old doesn't mean it's good.

Knowing whether old ideas are more likely to be good requires understanding whether conditions have changed in important ways.

Horse archery was an amazing method of warfare for over a thousand years...then people invented guns, and suddenly this great idea that had stood the test of time became obsolete.

Then again, when underlying conditions don't change much, tried-and-true approaches are probably better.

"Learning the lessons of history" usually just means assuming ergodicity and stationarity in an informal time-series model...

MY RACIST

If U remember from an earlier post I brought up Sen Elizabeth Warrens remark that "Obama did more for Wall Street than Main Street." I concur. U can ignore poor black people all day, but under no circumstance can U ever ignore poor white

Now Biden must be careful not to repeat the same mistakes of Obama. Biden most go big & go big fast. Fuck inflation. Order the treasury to start printing money. You will not beat Trump by impeaching or prosecuting him. You must beat him on the battlefield of ideas & you do so by-

helping the people he ignored. People with good jobs, food on the table & a roof over their head dont have time to do insurrections. If U help these people, you will choke off the fuel to Trumpism. Some black people will criticize me for taking this approach. My simple retort is-

you can't out-violence white people. We don't make guns. We don't make bombs. We don't make shit. You have to make it such that everyone eats. Otherwise you have to deal with the warning Heather McGhee lays out in her new book: white

Obama did not get this. He made it such that only rich white oligarchs got to feast. Everyone else got crumbs. I need you to get precisely what peace requires. There are a good number of white people in this country which would rather burn this country down than to allow any-

I’ve just finished some research about the use of biosolids (human sewage sludge) as farm manure. The results will keep me awake at night.
¾ of biosolids in the UK are spread on farmland. The rules about what it can contain are not fit for purpose. Please read and share this 🧵

Biosolids typically contain a wide range of synthetic chemicals, including antibiotics and other pharmaceuticals, personal care products, microplastics and persistant organic pollutants, among them “forever chemicals”. Yet testing is restricted to a small number of contaminants.

Spreading them across the land means spreading them through the foodchain and the ecosystem. There’s plenty of evidence of uptake of many of these chemicals by crops, earthworms and other soil animals, and of large-scale antibiotic resistance developing among soil bacteria.

When soil is blown or washed off the land, these chemicals enter the air and water. Some seep into groundwater. We're likely to eat, drink and breathe them. It’s hard to say what the health thresholds are, or what the combined impact of this cocktail of synthetics might be.

Yet the issue has been wilfully neglected by governments. Regulation is negligible. Farmers in the UK are “responsible for knowing the levels of any potentially toxic elements” before spreading sludge. But how? With an on-farm lab that can test for 80,000 possible contaminants?
