Ramanujan's Challenge

·6 mins
A bust of Srinivasa Ramanujan in Kolkata. Asking for Signs # A fallen-away Catholic friend once told me that he wished the Bible predicted modern science. “If Jesus said, ‘Oh, by the way, matter is made up of atoms,’ then I would also believe him when he says he’s God,” he said. I don’t think we should expect Jesus to have said things like that. First, it wouldn’t have helped anyone in the centuries before it could be verified.

Grocery Prices

Australians buying tea just before the price increases. Grocery prices are up, and my wife took the opportunity to do some comparison shopping. We currently shop at Aldi, of course, so her research question was, Is it worth it to buy Sam’s and/or Costco memberships and shop for certain items there? She concluded that it is for us. Here’s her spreadsheet. Enter your monthly quantities on the “Item Analysis” tab and it’ll show how much you could save at each bulk seller.

The game I knew in childhood as Sheep in Pens. I’ve got one math link and one meta-science link this month. Math: I’m excited about Ben Orlin’s forthcoming book of math games. Ben loves math and puns. He’s witty and perceptive. His post on being stuck is something I’ve included in work trainings to explain how data analysts should think. Science: Then there’s Bruce Charlton’s longform essay Not Even Trying: The Corruption of Real Science.

Jesse Tree

Tree of Jesse by Absolon Stumme. There’s a tradition in many Catholic families to make a Jesse tree in Advent. This means doing a reading from the Old Testament each day, and pinning a leaf with an associated symbol on it to a cloth tree on the wall. The name comes from Isaiah 11:1: There shall come forth a shoot from the stump of Jesse, and a branch shall grow out of his roots.

Careers, Ambition, and Humility

Dear Sebastian, I read your open letter on your economics curriculum. I happen to be thinking a lot about career advice at the moment, so the advice you include from 80000hours was interesting to me. I love the idea of including career advice in an economics class, and situating it right when the curriculum has caused that sort of angst in your students is perceptive. But I have mixed feelings about what I found at 80000hours, and it provides a useful framework for talking about the thoughts I already had brewing.
