Note that this is a research article. The target audience is other researchers in the field, who it would seem would already be familiar with this term. That target audience apparently doesn't include you, which is something that happe

Scientific publishing is one of the most parasitic industries out there. To be clear the authors of studies that get published at places like nature have very little leverage on this kind of thing -- it is the rent-seeking publishers that a

This is basically it, yes, along with cos(x) = 1. If the axis of rotation is much further than the distance that you move through upon rotation, the angle of rotation is very close to zero, so the approximations are very good. In the limit

The word axis can be used to mean various things. One of those is the line that a rotation happens around.

I'm happy to agree to disagree about where the line between "division" and "division like" should be placed. As you say, it is a question of convention and not really a question of math. But I don't agree that

Honestly saying you can't have a number 1/0 because it breaks the ring axioms seems exactly analogous to saying 0 can't exist because it breaks the group axioms for multiplication on the non-zero reals. Is ring multiplication

I didn't realise this, but apparently it is also possible to do good algebra on this kind of structure by adding an element 0/0: https://en.wikipedia.org/wiki/Wheel_theory (which someone pointed to in one of

Giving the answer that is relevant to the situation is very sensible. Saying that "this is the only thing division can mean in mathematics" is evidently false, though (I take it that you agree with me on this now?), and false in a

I am not at all concerned with what is or isn't possible in a computer for the purposes of this discussion. My only point with the link is that dealing with inverses in particular situations (i.e. where multiplication has or doesn&#x27

We redefine multiplication for new contexts every day in math, I don't see why division should be any different. See also: https://en.wikipedia.org/wiki/Division_(mathematics)#Divisio...

What you're saying is that the analogy between subtraction and division is good as far as it goes. So why should "as far as it goes" end at zero not having an inverse, rather than division by zero producing something other th

"_____ is not defined anywhere in math" is a kind of sentence that is almost never true, and even if it were, it would be impossible to prove that someone hadn't jotted a valid definition on a napkin somewhere. In this case i

Unlikely: assuming all of the authors of the various papers were on earth at the time, the spacetime intervals separating their discoveries were almost certainly timelike, in which case there is no ambiguity in their ordering. Unless they w

The previous couple sentences before what your parent quoted make this clearer IMO. e.g. they don't want hires to be "purely technology focused".

I think the idea is you want to avoid hiring the person who will quit if you eventually stop using their pet technology.

There are applications where the point is 3d graphics. I don't object to letting them use my gpu if they ask nicely. There are other applications -- really the vast majority of them -- where 3d graphics is completely beside the point,

What do you think there will be more of: a) existing functionality moves to more efficient implementation on gpu, or b) "hey, we can use gpus now, let's shove some more compute-intensive features into this app that add nothing but

by topaz0 4y ago
Incredible insight, but I fear it won't work out well: when the option is there and ubiquitous, websites will rely on it, so disabling features is basically choosing to save some of my resources in exchange for a broken web experience.

I'd rather not have websites soak up my compute resources, thanks. They are already doing that many times too much for my taste.

See my edits for more substantive points, but more generally it is really useful to formalize your argument. Once you do that, it is much easier to see what parts of the argument are on a firm footing, and which ones are inadequately justif

I believe you are mistaken. At steady state turning the steering is typically pretty subtle, and of course you can oversteer and have that mess with your balance in the opposite direction, but some steering has to be there to get the wheel

Common mistake: you are confusing energy and momentum, or power (rate of energy/work) and force (rate of momentum change). In fact, power at constant force is F.v (force time velocity), which solves your question.
