>avoid replying to yourself>ask anonymously>if someone replies to your question with a raisinpost, ignore it>avoid arguing with Yukarifag>do not tell us you came from whatever the fuck board, /soy/ in particular>do not mention how [other place] didn't answer your question so you're reposting it here>If you use j for the complex unit, put a ¿ somewhere in your post or use emoticons I will automatically ignore your question. I don't actually know about everyone else, but you shouldn't assume they're too far off about whatever random things they dislike №7710[Quote]

>>7719>Who is right?disagreeing in math means you have some kinds of proof to back it up otherwise it's just philosophy and philosophers disagree all the time.
social "sciences" are in a completely different category than math due to the problems with reproducibility
tell those niggers to start producing reproducible results then we'll talk
>>7736sieg heil brother. the ride never ends

It’s freezing cold outside, and warm inside. When I open the door, cold air rushes in, instead of hot air rushing out. Why?

see pic rel: Imagine line t in the plane carrying an infinite row of unit squares Iₖ, and you stand at a point p exactly x units above the midpoint of some finite subchain
Sₙ = I₁ ∪ … ∪ Iₙ. Your only move is "turn once at p, then walk straight" — if that ray hits one square you land there.
Let n(x) be the number of squares reachable in one straight hop, and record the jump‑heights B = { xⱼ | n(xⱼ)=j+1, j≥0 }, with x₀=0. Subtly: package all one‑bend paths into a sheaf F on X = t ∪ {p}, then push it forward by π: X→[0,∞) with π(p)=x and π|ₜ=0, yielding G = π_*F. By design, the stalk Gₓ has size n(x) and vanishes exactly when no square is reachable.
Question
What’s the critical height
x꜀ = inf{ x>0 | Gₓ=∅ } = sup{ x | Gₓ≠∅ },
i.e. the exact distance from t beyond which no single straight‑line ray from p can ever hit any square?

>>8882> How healthy it is to drink water from those pic related reusable bottles? long term: probably not healthy. all plastics tend to leech chemicals into water over time. short term usage shouldn't have any affect on health. i forget what chemical it was in plastic, nor do i give a fuck looking it up, but it can mimic estrogen.
> is the sterilization proccess safe?extremely safe if done properly.

>>7700 (OP)Dear biologists, there's a grebe in my neighborhood that can't get a partner because it keeps fucking up the last part of the dance where they dive under water to grab a weed. It fails to find its partner for a while and gets confused. It makes me wonder whether or not biologists have figured out how grebes are able to dance so well in the first place, what factors determine succes or failure, what that says about biology in general. Is there any hope for this sad grebe to learn how to succesfully perform the last step?

Gravity bends light.
Can light be set in orbit? If successful, you could create time capsules by simply observing the light which was set in orbit maybe 5, 10, or 150 years ago.

Is true consciousness a form of insanity?
As we're basically the universe observing itself from infinitesimally small perspectives that make a large whole, surely the universe is fractured and the deviations are a resulting insanity? Dogs all are "programmed" (let's say) like dogs, cats all "programmed" like cats, plants are all "programmed" like plants.
But not humans. We can choose to deny our base programming that was programmed by the universe. As we can each discern a self of self through higher brain function (as can other mammals such as dolphins, and even avians such as ravens) by recognising themselves through a mirror, isn't the very sense of a fractured psyche, in itself, insanity?

What solution do you use to remotely access files on your PC over a wireguard tunnel?
I tried the obvious already (SMB, SFTP) and they both fucking suck over high latency networks. Throughput and reliability are ass. In comparison, dumb "python -m http.server" works so much better, but is inconvenient.
What's the /tech/ way?

Assuming Darwinian evolution is real, I wonder if this capability emerged gradually in humans or if it's more like a bit flag that either grants you this consciousness or not, with nothing in between

Why do normies act like they have to throw their phone away because it no longer recieves software and security updates? Just don't download fishy APKs, stick to the app/play store. Just don't download things from emails of people you don't know.
I'm still on pixel 3a and it works fine.
