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.

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

07.10.2025 17:11 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

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.

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

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.

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

Do you have anything published on the notion of observers "going down branches" that you talk about at the end?

Nope I was totally wrong about this, the Born rule is still a problem over and above what is classically mysterious unless you’re convinced by e.g. the argument that it can be thought of in terms of self-locating uncertainty, which I think I agree with Adlam in not fully buying.

How long do we have to keep pretending that running arbitrary quantum circuits just automatically generates useful knowledge?

When you release a new paper, what are you most concerned about - the reaction of other scientists or the reaction of the market? Scientists in academia and industry have different incentives...

There should be no misunderstanding that this is utter and complete corporate BS. No quantum computers are needed for whatever they did in this work. It's a shame to see IBM depart from their fact-based approach. See Scott Aaronson's blog post: scottaaronson.blog?p=9170

I think this is a much clearer statement of the kind of "branch-wise aspect dualism" I've been circling around the last few days. Some configurations just do correspond to conscious experiences, and the level of mystery involved is precisely the level of mystery involved prior to quantum mechanics.
