And that's really all that's being requested here yet, for reasons which IMO don't need saying, MANY people find even that too onerous a burden. In my mind, it's the equivalent of refusing to stop calling someone the N-word or continuing to refer to people as retarded, and suggesting that people who request you do so are simply being too sensitive and ridiculous. They're not. They're on the receiving end of this and are being targeted by these words and subtle rejections every single day they exist... often for months, years, and decades at a time. It's not your place to tell others that these words aren't hurtful to them when misused, and it's not your place to continue hurting them through continued use or out of laziness or sheer refusal to move beyond historical tradition. Language evolves. Misuse of these words has fallen out of favor and their adjusted use now represents acceptable parlance in society for good reason. In much the same way you don't refer to a woman as sugar-tits, you no longer refer to a trans person who identifies as HE by calling them SHE... and thankfully those individuals who continue refusing to take the simple step of respecting pronouns of the trans community are ALSO falling out of favor culturally. You can either get onboard or get out of the way... you can either be a partner in improving society or attempt to stand in its way as an obstacle... but society will continue changing whether one likes it or not. Again here, the arrogance and lack of empathy is astonishing. Nobody is saying you can't or won't slip up... That's fine and WILL happen, but yet again here you dismiss acceptable, polite, and entirely valid requests to stop calling someone SALLY when they identify as JAMES with disparaging language like "whining" and suggesting it's no "big deal." Well, sure... Maybe it's no big deal for YOU, a cis-gendered male who's never had to battle daily slights and discrimination just for being who you are... but you're not the only person living in this world, nor are you the sole arbiter of what is considered important to millions of humans. This is about acceptance and authenticity. People are being shunned simply for being true to themselves. They are being targeted and ostracized, being brutalized and facing violence at unacceptable rates, and fighting daily battles against a culture who still too often treats them as subhuman. Maybe adjusting our own views and being just a bit more sensitive ourselves to their very real plight will help extinguish these disturbing trends.

Then do some reading, you lazy so-and-so. Nobody here is going to do your assignment for you. The world doesn't need a dud oncologist who cheated his way through medical school. If, having done your reading, you have specific questions, that's a different matter.

I'm sure there's a gif of the gaps too. There's a gif for everything!

I bet reddit.com/r/Whatisthis/ or reddit.com/r/whatisthisthing/ would figure it out within an hour. I figured it might be part of a tool, like a plane depth adjust, or a proportional divider knob. The closest I've seen is on a horological tool, like in the top left: The knob slides and tightens to lock. A string might fit in the groove, and the part is used to set the tension on it. This one looks like it spins freely though.

I think clarification is in order. Firstly, I was the one who posted this, not iNow. Secondly, I said only that ‘the world is essentially quantum’ - a statement I do stand by. What I meant by this, in the context of the discussion, is that there is no ontological difference between the macroscopic and the microscopic world; what is different is only the degree by which these domains are subject to decoherence; the larger the system, the more quickly it will generally decohere. This is why you don’t normally observe interference effects in the macro world. Classical mechanics is thus an effective description in the macro domain. But do remember that there is no law forbidding such effects - if you can find a way to delay decoherence for long enough, even macro objects would in principle exhibit such behaviour, at least for a short time. This is an engineering problem, not one of fundamental physics. I don’t believe that this is really in contention. None of this implies that ‘everything is quantised’, which clearly it is not. Even in standard QM the spectrum of hermitian operators is continuous until you impose boundary conditions on your evolution equation - it’s only this that yields discreteness of observables. Quantum-ness does not necessarily equal discreteness; it means primarily that there are pairs of observables that do not commute. And yes, I fully agree that quantisation of spacetime is very much under debate. I did not mean to imply otherwise.

Surely, if I have misunderstood, you can explain your point in more detail so I can understand ? The flysheet explains the scope of the book, which encapsulates the ongoing debate about the granularity (quantisation) or continuity of space and time and spacetime. Do you need more ?

God is often used as a way to explain things we don’t yet understand. The gif concept fills those gaps. However, as science and culture progress and we continue learning more, those gaps begin to shrink and eventually close, thus rendering the concept of God obsolete and unneeded.

Wrecked space vessels are much like wrecked sea vessels. Very little hope of surviving, so I find your "awful irony" more awful than ironic. Does this mean you wouldn't want to help them if that happened? What would that mean for the Outer Space Treaty?

Wouldn't it have been an awful irony, if their craft had been wrecked by some of the space-junk that China created by blowing up a sattelite in a weapons test a few years ago?
