My link roundup skipped last month. In the last two months, the ace journal club talked about asexual literary theory, and sexual pain in Christian women. I also wrote a review of Portalmania, a short story collection.
Has the Navier Stokes equation been solved? | Stand-up Maths (video, 23min) – AI has been used to solve the Navier-Stokes Millennium Problem. The Navier-Stokes equation is basically the equation of motion for classical incompressible fluids. But after learning some of the details, I’m a bit disappointed. Solving the Millennium Problem is not the same as solving the equation. Instead, they proved that there isn’t always a solution. Some initial conditions will result in a singularity. Of course in the real world, no singularity would occur, because the fluid would stop being classical and incompressible before reaching that point.
So the Navier-Stokes Millenium Problem is, deceptively, kind of a pure math problem without any immediate application. If you want to actually predict the behavior of a fluid, there are already numerical methods available, and the Millenium Problem won’t help you. Some mathematicians are pointing out that for pure math problems, the journey is more important than the destination, because that’s where we may learn new techniques. That seems fair enough to me.
Why I am not an Effective Altruist | Tell me why the world is weird – Perfect Number discusses her disagreements with the EA approach to global poverty (to say nothing of animal welfare or ex-risk). In short, she wants to give to causes that she has a personal connection with, even if they’re not necessarily the most optimal charities from the “objective” perspective. e.g. a woman who benefits from women’s rights might want to donate to causes that fight for women’s rights. Seems sensible to me. Although I would say, global poverty is not exactly disconnected from us, we beneficiaries of centuries of colonialism.
I donate ~10% of my income, mostly to GiveWell, plus maxing out my political campaign contributions. For all my misgivings about EA, Givewell seems pretty respectable and 10% a reasonable standard. But I don’t feel much connection to any particular cause, and I generally find the prospect of choosing between charities to be stressful.
Spooktober 2026 | Life’s a Gas – Bébé Mélange has this series where they share an idea for a spooky novel every day. I think these are neat.
