    All the typical weirdnesses of QM - the double slit experiment, observation collapsing the wave function etc. - are they still regarded as mysteries that need to be resolved, or is the view now that that's just how the universe is and there is no explanation beyond that?

    Isn't it the other way around? What we observe in nature is the weird looking stuff. And QM is the, or at least one, explanation for it? I do not see how you can take the observations that we make about the universe to not reasonably represent how the universe is.

    The "Nomenclature" section alone makes it look like a bad joke.

    If an AI species seeks to understand human behaviour, it has to interact with humans in their interaction patterns.

    This is important for anybody interested in the topic of this thread. Note it.
    If the topic does not interest you, you will surely find better entertainment elsewhere.

    But how to understand it?

    What use of the term "species" is employed here. There are many possible uses, I know one use of the term in Combinatorial Enumeration. There is a common use of the term in biology, is that the intended one? With one basic treat being the ability to produce fertile offspring?

    Would it be important in some context to understand the statement If a human researcher seeks to understand the behaviour of ants, they have to interact with ants in their interaction patterns

    Yes and proportional divisions can be any , but coordinates of cross point should be constant.

    What do you mean by an "arc" when you say "there is especial arc"?  An arc can mean a piece of the unit circle, or just an angle, in the context. Like, there is an arc from \(0\) to \(\pi /2\) and an arc from \(\pi\) to \(3\pi /2,\) or do you think of them as just the same arc, of length \(\pi /2\)?

    8/9 Pi is!

    Well, yes, well done! The OP seems to have in mind some kind of riddle,  to which the solution is an angle between \(5\pi /6\) and \(17\pi /18.\): ...there is especial arc in which if to connect any two points of proportional division of this arc and its chord by straight line and to connect any two points of any another proportional division of this arc and its chord by another straight line , then the straight lines cross in one point of definition of trigonometric functions and angles(arcs). Scratching my head to figure out what it means.

    There are many ways of defining the sine function. Some are given here: https://en.m.wikipedia.org/wiki/Sine

    Maybe it also helps to answer the OP's question to observe that the link given by Strange refers to a basic definition of an angle as a union of two rays that meet in a point. There is nothing about real numbers or approximations. The \(\sin\) function is then defined by assigning a congruency class of line segments to each congruency class of angles. Other explanations, more popular nowadays, are derived by assigning real-valued measures to angles and line segments. But the original definition needs none of that.

    Here are cameras on every corner and in almost every shop.. Bank will just exchange data with police where somebody attempted to withdraw cash or shopped. Police is going to shop and getting videos from cameras..

    Here we do not have cameras at check-out in ordinary shops. If you find a lost card on the sidewalk and use it to pay for purchases, you can do so freely, dispose of the card somehow and be free to go. In any case, if you worry about cameras, just wear a hoodie and sunglasses.

    Smart wallet thieves take the cash and everything else are throwing away. It disallows almost completely to identify them. If thief is going to ATM trying to withdraw cash, knowing or not knowing PIN, will be recorded by e.g. cameras on the street around, even if ATM has no built-in camera. Analyse of cell-stations who logged in and out will reveal thief phone number..

    Debit cards found here are valuable in any case. You take it to a shop, pick up goods, and check out paying by it. Only in rare cases do you need to know the pin, and if the teller should ask for it, the thief can just claim that he forgot it, and then leave to try the next shop.

    I meant are they still forming stars 

    not that it really matters anymore 

    Oh, okay, yes, they are mostly star forming, as Ghideon said already. But good that it doesn't matter, since then I do not have to feel bad if my answer is wrong.

    Go find a counsellor or  psychologist to talk to.

    Science discussion won't help you. You need to know why you want us all to be doomed.

    Doomsday is just fun entertainment to some people. Don't judge...

    We can learn to live with it...

    Very nice, +1. 

    Although treating Earth as an organism still seems crude. You cannot safely take what Earth has that somehow corresponds to a human leg and amputate it, or remove what corresponds to a kidney. If we treat Earth instead as an ecosystem, we would know that whatever we do to either part of it necessarily has an effect on every other part. And this is where you have to start taking in account what happens when you severe the wing of the butterfly that lives in the Amazon jungle.

  12. 16 minutes ago, dimreepr said:

    So, not the same???

    There are ecosystems on this planet that are entirely removed from both humans and bees, they mostly live underground/water...

    Sure, we agree that if we have two collections of organisms that do not interact at all, then they live in (at least) two distinct ecosystems. It is up to a definitorial property of an ecosystem whether humans and bees live in the same or in different ones. It is when, as you suggested, the ecosystems of bees and humans interact, whether that means that the two ecosystems necessarily fuse into one. It is not necessarily a scientific point. We can analyse any system of interactions between organisms as if they comprise an ecosystem. If they live together in an ecosystem that is not actually closed, we just have to adjust our conclusion to accommodate this fact.

  13. 11 minutes ago, dimreepr said:

    Do bee's need humans?

    Maybe not. But since human activity affects the living conditions of bees, it is fair to declare that we do live in ecosystems that are interconnected. Depending on whichever loose definition (here we go again) of what you consider to be an ecosystem, you decide whether the quantity of interconnectivity is enough to deem our ecosystems completely fused or just weakly interconnected.

    My ecosystem interacts with a bee's ecosytem.

    It is because it is the same ecosystem.

    EDIT: assuming, for the sake of argument, that you are a live person.

    I think life and it's ecosystem are co-dependant and inextricably linked, and so are qualitatively no different. 

    Insofar as an ecosystem, generally interpreted, means the totality of present lifeforms that interact with each other, and lifeforms are the perceived individual components of any ecosystem, this kind of thinking is not far-fetched. Still they are qualitatively different. Within an ecosystem, the different lifeforms have different roles in processing the chemical composition of the system. We can refer to the function of each different live object and abstract the totality of objects that have essentially the same function into a single species of life form. The converse is not quite true, at least not in the way that we ordinarily use language. Even a system composed of various essentially similar different ecosystems is not identified as a single life form, especially since by definition, different ecosystems do not interact. Lifeforms do interact.

  16. Just now, dimreepr said:

    Why?

    It doesn't seem to argue against a volcano being alive, since the ecosystem of a volcano maintains the property of having volcanoes (even if individual volcanoes eventually die, this is no different from standard lifeforms). And hence if volcanoes are lifeforms, then their ecosystem maintains life.
