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!

i am so ready for quantum to be the next dumb buzzword the tech industry forces everyone to pretend to care about. "how are you incorporating quantum into your daily work?" i'm not but it's so refreshing you asked me a new and different stupid question

you are literally saying a little prayer absolving yourself for using a magic 8-ball as a research method. it cannot hear your words or interpret them!!

I guess what I'm saying is does anybody have an fMRI machine they can stick me in/do we still believe in those?

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

But maybe I actually can only do one of them and most people really can do both?

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

I've always (or at least since my Dennettian conversion last fall) sort of thought that people are just very sloppy about how they *talk about* what's going on in their minds, and that this stuff about "I can see things vividly"/"I can't see them at all" was just confusing exactly those two things.

"The biggest source of confusion [...] comes from the assumption that “imagination” and “forming mental images” are one and the same thing [...] I’m able to imagine anything, except it is all devoid of sensory representations. The imagined objects exist in my mind as interconnected concepts"

My Brain Doesn’t Picture Things

I can’t imagine sights, smells, or sounds. What’s wrong with me?

Coming to terms with the fact that I probably do not have a novel perspective on the measurement problem

just watched a dozen people ask microsoft copilot experts their most pressing questions and those questions were 90% “how do i turn it off?” and “when i turn it off, is it really off or is it spying on me?”

I vaguely remember a similar thing with somebody asking Larry David if McKinsey could've helped with writing Seinfeld.

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:

Jeffrey M Epstein @jeffreymepstein.bsky.social · 7d

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 · 7d

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

Jeffrey M Epstein @jeffreymepstein.bsky.social · 7d

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.
