I was very kindly offered a chance to discuss my Frauchiger-Renner paper on the Quantum Frontiers blog! I attempt to situate the work, focusing on the philosophical motivations/commitments implicit in Wigner's Friend and the FR paradox. Cameo by another, unrelated obsession of mine at the end!

While I'm updating my website, here's a little blog post type thing about quantum conditional operations, in answer to a question I had a while ago:

Yeah exactly - somehow you have to bring signals from the two bodies together to one place where you can observe them.

Jeffrey M Epstein @jeffreymepstein.bsky.social · 1d

What would it mean to "directly" observe time dilation?

Jeffrey M Epstein @jeffreymepstein.bsky.social · 1d

Isn't that all that we can observe in the end? So if I want to observe "time dilation", I observe the nth pulse from a moving source arrives at the same time as the mth from a stationary one, for n < m (say the sources are both constrained to a circle around me to avoid correcting for travel time).

This thread now lives in a pdf here. I didn't do any further editing, so any typos and/or giant mistakes in the original thread are still present, but hopefully it's a bit easier to read.

Be warned: The declaration of a borderless State of Palestine creates a Palestinian state of mind that has no boundaries or limits.

Carlo Rovelli's book on Anaximander is pretty interesting from this point of view.

Jeffrey M Epstein @jeffreymepstein.bsky.social · 5d

Actually this is timely because I've been thinking a lot about how to take seriously the notion that people in the past were probably basically as smart as we are, so it's on me to understand how the absurd stuff they said probably did actually mean something and not on them to speak my language.

I haven't read the David Wootton review of @philipcball.bsky.social's Alchemy book, but Philip's response is insightful and well worth reading #histSTM philipball86.substack.com/p/was-alchem...

Was alchemy a load of nonsense?

David Wootton seems to think so; I disagree.

Would you believe I'm not?

LinkedIn message from some guy Sudheer Matta (or obviously his AI proxy) reading "Hi Jeffrey, As a Senior Quantum Applications Engineer, you're probably curious how AIOps can be leveraged to help improve end-to-end operator and end-user experiences."

Jeffrey M Epstein @jeffreymepstein.bsky.social · 5d

This is what gets me about this stuff. The good use cases aren't at all clear, and the bad use cases are obvious. It's not even progress for progress's sake, it's a case of a tool being developed that will clearly be used for ill, without any argument that this is outweighed by anything good.

So you agree. You think you're really good at running a campaign.

the extwitter mindset is ultimately about a contempt for knowledge. it was never about "science vs humanities." it is about the idea that it is worthwhile to understand the different facets of a complex system even if you cannot provide an immediately instrumental justification for doing so

Lakshya Jain @lakshya.splitticket.org · 8d

I get this reply a lot. I think people who don't study computer science genuinely do not understand how it's taught.

You *have* to understand logic gates. In Berkeley, students are also made to learn assembly. Less about the language, more about principles. www.theargumentmag.com/p/chatgpt-an...
