There’s a recent paper on the formation of such a “kugelblitz”; it’s argued to be unfeasible. https://arxiv.org/abs/2405.02389

How about rthym or some variation?

Someone call @keithw. He put a tremendous amount of brainpower into getting the Unicode side of this puzzle "right" (or, as "right" as it is possible to be) when he wrote mosh. I'm sure he and Hashimoto could have

If the analogy to warped spacetime was exact, then there would be a “scale factor” for every point depending on the local transit speed. Then it would be possible to do as this page does and for the answer not to depend on starting point.

Does it still go rancid if it’s kept at boiling temperatures? I’m guessing that if it’s too hot for microbes, then you only have to deal with oxidation at the surface, which can maybe be fixed with periodic skimming. Maybe?

AIUI, there is a technical criterion for an ambient EM field to imbue circuits within it with broken time-reversal symmetry. One example of a system that meets the criterion is a ferromagnet. Another is this altermagnet. One example of a s

:shocked_pikachu: Renegadry aside, for those who are more interested in the Information Theory perspective on this: Kolmogorov complexity is a good teaching tool, but hardly used in engineering practice because it contains serious foot-guns

I think you’re putting the right spin on this.

I love the drama of how the abstract is written, but TBH I don't think this is a surprise. I believe it's well-known among color theorists that large perceptual distances are inconsistent with sums of small differences. So maybe

I don’t see how the author’s arguments about impossibility results pertaining to “distributed sub-symbolic architectures” apply any more strongly to LLMs or DNNs than they do to human brains. Human programmers aren’t magically capable of s

So many footguns in this proposal! From the misleadingly symmetric symbols <= => >=, to the unintuitive behavior (for non-mathematicians) in the case of negative left argument, to the similarity to operators in other languages. S

I haven't studied antitrust policy in ages, but IIRC one aspect of this in the past has been to forbid the monopolist from peeking at their competitors' prices.

Yes; however, because of the extreme kinetic energy and momentum of the cosmic ray inputs to these collision events, the output neutrinos will be emitted in a tightly focused cone parallel to the path of the original ray. You can be fairly

There are a number of red flags here. The author puts a lot of breathless energy into airing grievances and lodging accusations. I find I don't much care: I want to know whether they have identified an experimental, quantitative, or p

I use it from time to time for work. It lacks some of Mathematica’s typographic flair (can’t ctrl-^ to get a superscript box or / to get a fraction) but IIRC has better undo support on desktop and satisfactory performance as long as y

Um. I rely heavily on Apple products, and I subscribe to some of their services for a couple bucks a month because I genuinely get a lot of enjoyment out of them. I find Apple's upsell mildly annoying, sure. But (a) the things they o

You don't get the entire wave-function as output; the wave-function is not observable. Different measurements might reveal information about certain components of the state, at least probabilistically, but those same measurements will

What you describe with finding the closest TLE is pretty much what they did. We use a highly directional antenna (~1-2 degree beam) and some tracking software, so it’s not ambiguous. I’ve been able to demodulate and reconstruct about 100 s

Their antenna was a CotS LNBF. Think just the bit on the end of the arm of a DirecTV dish, not the dish itself. Typical aperture maybe 10cm, full unit about hand-sized.

Can’t speak to the regulations, but essentially the answer is “yes”. Our publications can be found under the moniker “fused LEO GNSS”. Those of Zak Kassas and his students can be found on their website.

The particular signal they used can be captured with a $40 low-noise block w/ feedhorn (I’m using the Visiblewave Hybrid LNB), a 12-16 VDC biasing circuit, and a garden-variety SDR. I speculate, based on my own studies, that the signa

Accuracy will depend on whether/to what degree SpaceX commits to providing a positioning, navigation, and timing (PNT) service. The technique used in the article is quite powerful and general, but it does have certain drawbacks too. O
