Hello guys.Today i got my first calculator.How does math explains that something is happening "randomly"

>> No.11143828

It pretends it's not random and looks for some crazy-ass equation that fits the points graphed as well as possible.

>> No.11143952

random is not a real thing. there is no such thing as randomness. it is one of the stranger axioms of modern math.

False.

Nope, you're the retard here.

it's a pseudorandom number anon.

okay big boy. define random.

True random numbers can be generated using quantum experiments.

Okay and what if we are just not advanced enough to be able to predict quantum indeterminacy.

if something happens 'randomly', what is meant is that it happened indeterminately. as in, there actually was a reason it happened, a pre-determined reason at that - but it may have happened so quickly that the human eye or measuring device just gives up. this is especially egregious against a human eye, which may consider something as slow as a simple coin flip to 'randomly' produce either a head or a tails.

more often than not, the phrase of 'randomness' is intertwined or outright confused with 'probability', an entirely different concept.

all in all, 'random' is the equivalent of a caveman watching an airplane fly through the sky. the caveman thinks it's magic because it's beyond his scope of understanding. Is it actually magic though?
is anything actually 'random' though?
no.

even the creation of this universe wasn't random. the creator just completely misinterpreted what "give me something new" meant, and seemed to disregard that all universes before this one had already validated as 'something new' despite sharing common rules, themes, and freedoms. So that's why we live in a universe where retarded and terrible shit happens.

So you can predict the exact moment an isotope decays right? Good luck

>> No.11144544

>>11144531
Isn't that just because of heisenbergs uncertainty principal though.
We cannot observe an atom without stimulating it in some way, you can't just look at an electron without shooting a particle or wave at it an measuring the result.
So just because we can't look at its inner workings we take averages, like half life.
If we could see the atom passively we could predict it's decay, but no such way exists, it's outside the limit of our technology.
But we could in theory.

>But we could in theory.
we can't though. measuring is part of "theory" and the act of measuring changes the isotope. measuring cannot just be arbitrarily excluded from theory

Almost all real numbers are completely random.

There are no hidden variables. Bell's experiment.
