General Relativity admits the concepts of wormholes (Einstein-Rosen bridges) and these are a nonlocal phenomenon. So it is incorrect to assert that quantum entanglement is the only nonlocal interaction or phenomenon. Both General Relativity

by qubex 3y ago
To be perfectly frank, quantum entanglement and wormholes are just the manners in which QFT and GR respectively manifest the concepts of nonlocality. That’s my understanding of the ER=EPR dictum, anyway: physics is fundamentally nonlocal, a

I’m a very happy (and I believe competent) Apple Numbers user. The only thing I miss from Excel is recursive evaluation (which is necessary for evaluating certain financial models).

I’ve tried to appreciate SymPy but I always find myself running home to Mathematica. There’s simply no comparison. SymPy is like a match and Mathematica has the power of a sizeable thermonuclear warhead.

Yeah I get that, it’s not a single Voyager, it’s millions of them sent out radially in random directions and random speeds and one or two of them just happen to thread the needle and go on the Grand Tour. It’s just an impression. Plus as yo

Indeed. While reading that I thought to myself “gosh, that’s a lot of needles that got threaded right there”. It feels like the Voyager Grand Tour gravitationally-assisted trajectory… happening by mistake.

It’s only a matter of time before some AI ‘textbook’ on some obscure field of medicine or surgery gets somebody killed.

Yeah that’s a good point: if substantial value is added every month (as in a streaming service), a subscription model is not quite so offensive. Subscription models for software that remains essentially static (aside from bug-fixes and occa

I’m so fed up of paying for software subscriptions. If I can choose between a single payment and a subscription service, I go for the one-shot every time. I don’t even know how to describe it, but it just nauseates me at this point. I’ve al

I actually own a copy of that magazine — I have the full first two years in holding cases. I feel so amazingly old.

I’m not going to take sides in this, but I am going to mention that twenty years down the line we’ll have fascinating comparative studies with really solid data.

Thank you for your very comprehensive and insightful reply. As an applied mathematician specialised in entirely different fields, I must ask though: why the focus on the centre of mass of the whole infilling object? Surely one can subdivide

I doubt this thing is waterproof, but I still admire the aesthetics of it.

If you think about it carefully you’ll realise that a human being’s body would span a breadth of radii and therefore the parts closer to the singularity would not be able to send signals or matter to the parts that are further out, and that

by qubex 3y ago
Aside: the fact that the radial spatial dimension towards the centre of the black hole where the singularity lies becomes time inside the event horizon is why all the drivel about “what you’d see if you crossed the event horizon” is drivel.

The fact that Linux dominates does not entail that other architectural approaches may be more suitable for the task. Variety is the spice of life and the “Linux monoculture” might not be such a great thing. BeOS/Haiku, Plan9/Infer

How about these venues threaten to shine a 3000 watt light on paying viewers instead? I mean seriously, this is inane. The precedent must not be set.

The whole thing is positively dystopian in vibe, but what struck me most was that businesses were being asked to pay on the basis of potential occupancy and not on the basis of how many patrons may actually be on premises during the race. T

It doesn’t actually surprise me that hybrid genetic/memetic approaches outcompete purely genetic approaches: after all, hybrid genetic/memetic humans have outcompeted purely genetic species at every level.
