/sci/ - Science & Math

What does /sci/ thinks of this study?

Although my experience obviously anecdotal, I have a feminine face and my girlfriend who says loves me to death, takes contraceptive pills.

Welp no matter, the study is legit

n-back is more predictive of academic success than IQ.

AHAHAHAHAHAHAHAHHA oh wow

Scientific community:
>Particles behave completely random at subatomic level.
Logic:
>B-but naturally there has to be something that we can't detect that affects the particles to move they way they do.
S.C.:
>NO! NOTHING AFFECTS THEM, WE CHECKED, THERE AREN'T ANY VARIABLES THAT COULD AFFECT THE SAID PARTICLES
Logic:
>How about variables that cannot be seen by our current methods, dare i say "hidden variables"?
S.C.:
>Oh you silly boy, we're grown up scientists, ofc we checked for "hidden variables"
Logic:
>Umm, by definition if the variables are hidden then our instruments cannot detect them, that's the whole point of the hidden variable hypothesis.
S.C.:
>How many times i must say, we do have such instruments that allows us to detect any variable that can affect the particles, they just are random, no interaction occurs.
Logic:
>Welp, you also accept Entanglement, which assumes there is an interaction from distance that isn't direct or how you say "local", you haven't manged to explain how entanglement works yet, but you exclude any chance that the subatomic particles can be affected by other means like non-local variables, hidden or not.
>If these variables were non-local like the entanglement phenomenon, couldn't that explain it? By extension the current scientific limits assumes there are things we just cannot know yet. It is unscientific to just presume we have excluded such thing as any kind of variable that could affect the subatomic particles.
S.C.:
>Bah, it's science bitch, Heisy tolds us, he had a degree, what do you have? faggot lel gfto, my peers got my back, get rekt faggy

hey guys

im doing the electrolysis of water with a 20% KOH solution (potassium hydroxide). I want to make it as effective as possible for my uses.
How do i calculate the decomposition voltage (voltage needed that the electrolysis starts). i have been reading ranges of 1.2-1.7 V on the internet. but i'd like to know the exact formula with explanation.
the pressure is 1 bar and the electrodes are made of stainless steel and have a surface of 80cm^2
question 2: does voltage (other than decomposition voltage) play any rule in the electrolysis of water or do you only want to have as much ampere (current) as possible
