Woah, was it that disruptive?

Oh I appreciate you actualling my actually ^^ but isn’t this case a special case of the one I wrote? I.e. when an and b are manifolds and admit tangent bundles?

Yes! I love Conal Eliot’s work. The one you wrote is the compositional derivative which augments the regular derivative by also returning the function itself (otherwise composition won’t work well). For anyone interested look up “the simple

> In fact, Nim first compiles to C which in turn is compiled to machine code by the C compiler of your choice (gcc/clang). Can one use the zig compiler after nim has compiled to C?

Mmh, this is a bit sloppy. The derivative of a function f::a -> b is a function Df::a -> a -o b where the second funny arrow indicates a linear function. I.e. the derivative Df takes a point in the domain and returns a linear approxim

Back when I was in high school I read a book ("the speed of dark" by Elizabeth Moon) which is written from the perspective of an autistic person who works for a pharmaceutical company (I won't add spoilers). It was full of nu

“The mission scans nearly all the planet’s land and ice surfaces twice every 12 days.” What was wrong with saying once every 6 days?

I’m curious, are they now fully autonomous? I remember some time ago they had a remote operator.

Nowhere near close, but getting every day closer. And you should factor in for how long secrets need to last.

I didn’t mean it’s the only explanation, but it sure is a knob that companies use to tune “growth” (or fake growth, for that matter), among other things like better technology.

I fully agree. Additionally, stock price is driven also by expectations of further growth, which in order to keep happening, something's gotta give so it must chip away at quality of the final product too (cheaper materials, cheaper ma

Yes I know addition and multiplication don't commute, but what does that have to do with the discussion above? Do you mean that repeated measurements on different systems might not be independent because they come from the same source?

I’m not sure I understand. Expectation values are just scalars, why wouldn’t they commute? Can you explain what you mean?

About 20 years ago I used to volunteer for CICAP, the Italian skeptics society. One year we had a big convention with lots of cool speakers. Obviously also some weirdos with wacky ideas showed up at the venue. I will always remember how Mar

Quantum physicist here. I can only say that reality down there at the quantum level is really really weird. You can get used to it, but forget making sense of it. A delayed choice setup is not too dissimilar than a Bell inequality violation

I was at a physics conference once and the RGB cable for the presentations was a bit faulty and one of the color channels wouldn’t work, and this presenter’s slides were all tinted cyan. After a bit of jiggling it finally worked and the sli

How do they know the causal link? Can it be that people who stay up late sleep less and this causes issues, and there being light is only a consequence of staying up late?

The confusing bit to me is that the LHS of this {greeting, thing} = dct is a set, which is not ordered, so why would greeting and thing be assigned in the order in which they appear?

I love these engineering "hacks". Similarly, a friend of mine wrote a paper on how to use the GPS signal as radar source (so you only need a receiver) [0]. [0] https://udrc.eng.ed.ac.uk/sites/udrc.eng.ed.ac.uk

That would be my no 1 go-to, if I didn't have to remain alert for my 3 year old sleeping next door (he can seep through the noisy neighbors though!)... (btw our neighbours are underneath and they cook at night, and talk very loudly)

How did you make the world not pick up a geometric phase as you move it around? It's always oriented nicely.
