Charm, quark, colors, time crystals, holographs.. And now, magic. Don't worry Einstein, no spooky action at a distance here, it's just magical. > The more non-Clifford gates you need to produce a quantum state, the more magical that state is. The group found that the particles were highly magical. ..They showed that magic gave space its springiness . Magic, in other words, is connected to space’s ability to bend. At…

Is it measured in Thaum? (which, as everyone surely knows by now is the amount of magic needed to create one small white pigeon or three normal-sized billiard balls)

> This naming-proposal couldn't possibly cause any problems down the line... Your worries are a bit late, there's already a huge amount of new age conspiracy bull about quantum healing with wave function collapse, microtubule alignment and biophotons - quality all-you-can-eat word salad buffet.

Don't underestimate the capacity for the problem to get significantly worse.

That's how science always worked. The stupid people throw money at smart people and sometimes they pay back with good things. Any attempts to optimize that is futile, so the best we can do is to continue throwing money.

Calling something 'magic' is like an admission that you have no clue about what is going on. Seems to me, they do have some clue, namely that instead of codes with perfect isolation, there might be some advantage to studying ones that allow some blending. The resulting spaces may (or may not) lead to a better description of reality, but doing science means to peel back that mystery. So to go and promote this under the term 'magic' is disingenuous.

Also, if all you have is a dual model, then it’s equally accurate to say entanglement arises from spacetime. Eg, this article describes entanglement giving rise to wormholes, but the model equally says wormholes give rise to entanglement.

They’re promoting their preferred frame to ontological status when you can’t use a dual model to assert more than equivalence between frames.

Earlier quoted context omitted.

we had "god particle" too …

To be fair, that one came from an editor not a physicist; the physicist wanted to call their book «the goddamn particle», and it got censored/editorialized to «the god particle».

Is that really where the name came from? I remember being struck by how dumb that was and thought “a journalist must have come up with that”.

> this whole field is starting to feel more like a jobs program for mathematicians out of new ideas. So sick of seeing phrases like this. Science is not business. It is not about producing results that you personally think are important. It is understanding the nature of the universe for the sake of it.

There's a lot of ire for string theory. It's non-testable and wound up attracting lots of minds, funding, and resources. It hasn't seemingly led to any tangible results. Many scientists express anger about it and claim entire generations of progress were lost.
