How can strings be one dimensional if we live in a 3d world?
They are like numbers: They don't exist.
>>8241772
It's like a point particle, but instead of a point it's a 1D string.

How can there be cats if we live in a doggy dogg world?
I am about to destroy this board. First we need a trivial proposition
If a and b are two real numbers and R(x) is a rounding function then
[math]R(a)\neq R(b) \implies a \neq b[/math]
Hopefully this result is obvious for everyone. By the way I am speaking of rounding as in 'rounding to the next x'.
Now consider the numbers 1.00 and 0.9999999...
If you round them to the second decimal place you get
R(1.00) = [1.00] = 1.00 = 1
R(0.999...) = [0.99]99... = 0.99
1 is not equal to 0.99
Therefore 1 is not equal to 0.99999..
EASY
Wow your shitty rounding function doesn't even round properly congrats
>>8241722
no rounding function is injective. the "trivial" proposition is a lie
>>8241722
That's truncating, not rounding, you fucking idiot

hypothetically could you convince a child that they died in Stalingrad in 1943 and have them believe that for the rest of their life?
we can partially erase memories but we can't place them yet. i'm sure we'll get there though
Well you can teach millions of jewish kids that they have met Josef Mengele. It shouldn't be much more effort.

I got diagnosed with shizoid personality disorder but i feel like a warm and empathic person.
Is this all in my head and i cant realise it?
>>8241513
So-called "personality disorders" are a blatant Foucault-ian attempt to discredit and pathologize alternative opinions that oppose prevailing social norms. According to the DSM, a pattern of behaviors is classified as a personality disorder when it significantly impedes social and/or occupational functioning. But social and/or occupational functioning is a two-way street: you can't function socially without other people. So there's nothing inherently "disordered" about personality disorders-all they indicate is a disconnect between a person's beliefs/actions and prevailing social norms. Don't think the descriptions as symptoms, but rather as an explicit description of the social norms that you might have failed to pick up on and/or conform to.
>So you're saying that people shouldn't take responsibility for their beliefs or actions-everything is society's fault
Not at all. What I'm saying is merely that personalities can only be "disordered" relative to mainstream social norms. It wasn't so long ago that homosexuality was listed in the DSM. Similarly, before the Civil War, a slave who wanted to escape could be diagnosed with a mental disorder called "Drapetomania". There is no question that either of these "disorders" would have caused the afflicted great anguish.
So if your symptoms really are causing you distress, then by all means try to fix them. But if not, then don't be afraid to reject the diagnosis, and don't let anyone gaslight you by trying to convince you that "it's all in your head".

Well stated.
Suppose you have a friend with two children. He tells you that one is a boy born on a Friday.
What's the probability that both are boys?
Well, /sci/?
50%, we've been through this before
>>8241508
assuming no other information is available, roughly 50%.
I don't know if having one boy makes it more likely (genetically) to have another one or something like this, but I doubt it.

How does it feel /sci/? Even us autists in 95th percentile for IQ will be obsolete! No only that, but they'll probably be better looking, more athletic, have bigger dicks, and live longer than any of us. We'll have to m'lady our way through life, working dead-end jobs and living under a bus shelter - if we don't kill ourselves.
We'll done, science. Well fucking done.
>>8241457
that's the point.
the world is very idiotic and everything needs to burn to make place for rebuilding a new civilization with different standards.
the sooner we realize that, as individuals, we are pointless and small, the sooner it will happen.
Hey /sci/, /k/ here. I was wondering, do you have any preferences on where to buy chemicals to use in just general experiments?
Specifically Sodium, Aluminum powder, Magnesium ribbons, and red Iron oxide powder.
I've been interested in doing some experimentation with sodium because I'm scared shitless of explosives, even stuff like tanerite, but sodium seems very stable and can be relatively safe to use.
And my friend just moved into a new house and has some old appliances that would be fun to burn threw, since we usually just shoot stuff like that.
Also, if you know of any other experiments that are relatively safe, feel free to suggest them.

> In the centre of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate. This causes a tear in the fabric of space-time.

How is this even possible ? How can the physical nature of the smallest building blocks that make the entire universe just "break" ? Is this basically an inevitable defective glitch of the simulation ?
>>8241156
>implying anyone, let alone /sci/, knows what happens at the point of singularity
>>8241156
It means it's a singularity, and there's nothing you can say, mathematically, about a singularity, save, "Yup, that's a singularity."
There's limits to verbal and mathematical descriptions.
Though you can still say all sorts of things about the consequences of its existence to things around the singularity - including predicting its eventual evaporation.

how about using the wings of an airplane as servo tabs? have the aileron be the anti-servo tab. ofc this would mean that the wings have to be very weak to twisting forces but they could still be strong otherwise.

That one is funny - it's even more funny, that it was proven recently that psilocybin adds neuronal mass to the brain, extensive use would force the monkey to have a bigger - at first useless brain that would in time adapt to become useful.
Why does the hot air in the room become fresh when moved by the fan?
because the blades of the fan slice the bad air molecules which cleans it up.
>>8240931
something something evaporative cooling something something
it's hot, you sweat, the air takes up the liquid from your skin, it cools you down
it takes energy to convert liquid to gas (heat capacity for phase transition), so when liquid sweat is carried away from you as vapor you're giving up energy and feel cooler.
The fan increases the rate at which sweat is evaporated.
So the air is as hot as before passing through the fan?
