Using quaternion pairs for 4-space rotations relies on the simple fact that each quaternion represents a hyperplane in 4-space ( https://en.wikipedia.org/wiki/Transformation_geometry ). Using single quaternions to repres

Isn't the mirror stage really about discovering the unity of the body (as a kind of closed contour), thus permitting entry into the Imaginary? Then the Symbolic is initiated when these entities (of which the body's image is suppos

I know HN is kind of a safe space for engineers to express their (sometimes arrogant or poorly informed) opinions about other people's fields. But this seems over-the-top. Who are these "ridiculous" people in New York, whose

This is a good example. C made the transition from "hot new platform" to "infrastructural millstone" before conferences on trendy programming topics were a thing. The original Bourne Shell was written in an odd preproces

I'm pretty sure Alexander would see the same problems in most Barcelona architecture as he does in other cities. The design in Barcelona is very good by the standards of European cities (and exceptional relative to a lot of places) but

I don't understand your comment. I think the site is trying hard to strike a nonjudgmental tone. Yes, poppy seed tea is a way of taking opiates. The point being made is that the dose is difficult to control.

No, this is about withdrawal symptoms. When you stop taking certain pharmaceuticals, you may experience withdrawal symptoms that aren't just a return to how you felt before you started. In the case of antidepressants these symptoms som

It's probably culturally dependent. I'd like to tell you that you can just ignore people you don't want to disturb, regardless of their relative social status, but I'm sure that's not always true. https:/&#x2F

I don't know exactly where you are coming from, politically (or religiously). But I believe that phenomena like narcissism constitute poorly understood pathologies of personality, and to be able to see them for what they are, clearly,

I hear you, but I think what's happening, in terms of psychological insight, is that millennials have more insight than earlier generations. They are also more likely to have narcissistic traits. The vigorous conversation about these i

You've been lucky, evidently. The idea that everyone is fundamentally OK, and that we just have to get along — well, in some cases, the effort that takes is just unsustainable. Maybe you're saying that you think there's no su

It's OK to distinguish between healthy and diseased specimens of any organic phenomenon, thinking included. e.g. Trump is a toxic narcissist, etc. I can't really take this article seriously as a comment on literature because it us

On the other hand, photo albums were quite often tedious props for narcissism. (I have some relatives who force people to sit while they narrate slideshows of holiday snaps on a laptop; new technology, same old pathology.)

There are obviously classes of objects that we don't have hard-wired detectors for. The face is one of the few that I've heard claimed as wired from birth. But I think "feature detectors" are exactly what the earlier com

I think the GP didn't mean to imply that humans have an innate cat representation from birth. It makes more sense to interpret the comment as saying that humans don't learn an internal image representation. Humans do learn rep

It means that a data structure is an object which supports a very limited range of algebraic operations. E.g. for a stack, you just have push and pop. That's the whole set of actions for that data structure. You could argue that it con

You actually made pretty bold claims about discontent being the human condition, I'd say they need proper justification if you want them to be taken as universal truths, not just personal opinions.

Unfortunately, as with the idea of batteries for electric cars that can be swapped out at the charging station, there is an incentive to hold onto better units, and quickly return inferior units to the pool. It's a case of Gresham&#x2
