My mom thinks I should do something more useful with my life than a PhD in foundations of physics. Little does she know that my back-up plan is philosophy of language.

I just got a copy of this new book from Emily Adlam (with whom I did my masters, so this is the first book I'm reading written by a former classmate!). I'm going to try the thing where I tweet about it as I go.

Let's have some fun. In this NYT story, we see a picture of an OpenAI billboard on a college campus, suggesting the following prompt: "Give me a guide for mastering this Calc 101 syllabus. In two weeks. Small steps please."

Excited to announce I'm recruiting for my first two Postdoctoral Research Associates! These 5-year positions will allow the holders to dive into applying quantum foundations to understand and develop quantum advantage!

I was responding to a talk by philosopher of physics David Albert (DA), in which he expressed dissatisfaction with various approaches to reconciling the asymmetry of causation with fundamental physics. He was skeptical that causal models could help, but ended by inviting me to say more about this.

📸Quantum photo
This photo was taken with a DIY dual pinhole lens.
The holes are close enough to reproduce Young’s double-slit experiment,
demonstrating #light wave-particle duality.
Look closely at the sun on the top right to see the characteristic interference patterns.

the rules for being a good naturalist are that if your explanation appeals to something that doesn't intuitively seem like ordinary physical contact between objects, it's magical bullshit, but physics is allowed to have whatever magical bullshit it wants and that's cool
