Vegetarian AI guy. Clueless... Zoute popcorn. Does word order matter more than world order? Chips are potatoes too. There ain't roombas in the sky 🛸

    Ben Thomson: "there may not be a significant paradigm shift on the horizon" which I read thanks to . Is there nothing left after mainframe, pc, laptop, and smartphone? Is this it!?

    Einstein's clocks, Poincaré's maps by Galison contains a lot of info on tech at around 1880. Did you know clocks were coordinated using compressed air? Electrification of time had yet to come!

    An Opinionated Guide to ML Research: “To make breakthroughs with idea-driven research, you need to develop an exceptionally deep understanding of your subject, and a perspective that diverges from the rest of the community—some can do it, but it’s hard.”

    There are many more that can be found in optimization theory. I think Lee Smolin would/should like to read up on computer science rather than - kind of - bash it. 😀

    Positions depending on momentum and momentum depending on position is nothing special. A common "dual estimation" problem such as Simultaneous Localization and Mapping (SLAM) in robotics.

    Einstein's Unfinished Revolution (Smolin, p262) is a bit quick on "dual equations" being restricted to physics. Even worse that computer analogues are therefore unhelpful.

    However, if our universe on a macroscopic level is a causal loop it doesn't tell us much over the microscopic level. Even if there are a lot of loops, there are still even more events caused by something in the "past" than the "future" of the large loop we're in.

    Time travel is then possible, theoretically, paradoxical time travel is not. If you would be able to shoot your grandfather, that world cannot come "into existence".

    How it's possible that we live in such a "rich" causal loop? Somehow all grains of sand, all fallen leafs, are like sequences of digits in a transcendental number. Is this superdeterminism?

    Smaller loops can exist as well. As long as the annihilation of the particle does not contradict its creation.

    What if it is completely the opposite? The only events that can arise are the ones that are "consistent" in the following sense. A causal loop can be arbitrarily "big". The universe exists because it causes itself.

    Causal set theory by Rafael Sorkin looks interesting. A condition: an event is never its own cause.

    Perhaps we haven't studied such types of symmetries enough.

    Symmetries of "configurations", say molecular structure in chemistry, to symmetries "across scales", such as fractals do not seem to require such a "background".

    I was triggered by Smolin's statement that symmetries are always defined by something "external". That sounds only true for rotation, translation, etc.

    Down the rabbit hole after reading Smolin. Found an article studying fractal differential equations and postulating an analogue for Noether's theorem (on fractal sets).
