seriously nobody?

Wrong board, /sci/ is for QI and religion, you have a better chance on /pol/ or /b/ (I'm serious, especially for /pol/) if you have a question that require more than high school knowledge.

To answer partly to your question you need that :
-f(a) R g(a) for every a in A
-f(a) R g(b) and f(b) R g(a) for every a,b in A

>>9077817
thanks man, guess I should have known better haha
naturally you also need that if f(a) R g(b) and f(b) R g(c) then f(a) R g(c) for every a, b and c in A.

But I'm actually looking for less trivial requirements for f and g. It's a tough question I guess, but I can't think of more requirements or properties f and g might have.

are you confused about why applying a force moves a load?

>>9077280
the inclined plane

>>9077404
ok you know how the gravitational force is always pointing down right? well the component that's actually active against your force will only be a component that's perpendicular to the inclined plane. alongside that, the normal force is going to be counteracting the initial startup of movement, but only the component that's perpendicular to the plane agan. these are all broken down using right triangles. you can also use the dot product depending on how comfortable you are. i can draw a graph to give a better explanation.

>falling for the nofap meme
OP confirmed for pseud

I had much higher gainz after stopping NoFap
Considering testosterone [math]\implies[/math] gainz, I'm certain NoFap is a meme.
But I'm just a broscientist so what the fuck would I know

You're the one that's turning them into feelings. They're literally just mechanical waves.

>>9074071
How does the brain turn mechanical waves into feelings?

>>9074081
I don't know, personally.

I assume you're talking about sound waves hear, judging from the OP picture.

I did find those short article on music and the brain <http://serendip.brynmawr.edu/bb/neuro/neuro99/web1/Sancar.html>. It's from the 90s, I'm not sure of it's value, but you can look into the papers it cites if you want to be sure of it's scientific validity.

It seems that the brain is specifically geared towards recognizing logical patterns, and patterns in music are everywhere. If you care to examine how music develops patterns, I'd recommend reading "Fundamentals of Musical Composition" by Arnold Schoenberg, which details methods of creating patterns by repeating and varying single melodies. It is a book written for classical composers, bu the general idea holds across all music, including non-Western music.

I'm not a scientist, and I'm no the best composer or musician, but I hope I've been of some help.

Poker, since you don't have complete information.

You can't compare them as they are of two incompatible natures.

finally got the PhD but now I can't keep up with my projects.

It's of course related to doing a 40 hour job now, but there's also social media I think I should do to break out of basic wage life, and that crypto shit which magically seems to be a money machine. I try to combine that with dependently typed memes as good as I can, but I must somehow externalize some capacities. Maybe I'll find a schedule that works for me and then I'd like to do time series and probability, as this relates to everything.

Fuck off highschooler.

conjugate
back to classroom

This is a routine problem of the sort you should learn how to do in class.

Multiply the top and bottom by the complex conjugate

>>9078791
You don't process information really fast, that's why you failed your exams

Just look up pomodoro method. Build the discipline of high focus for 3-4 hours at a time by starting with just 1 hour of high focus. It's like a muscle, you have to build it up. It's not an easy fix, it's discipline. Also you procrastinate because you're scared you won't be as smart as you think you are, because studying involves trying and nothing is more humiliating to you than trying your best and failing anyway.

Now fuck off

Unplug yourself from social media, of other people. Listen to your own brain and don't try and force it if it doesn't want to. Find solace in its own limitations and work with them, not against them to achieve equilibrium.

>What's the evolutionary purpose behind modern blacks having big black penises?

It's so that white women had an alternative to small white dicks, of course. Are you little dumb, son?

>>9078535
Evolution does not work like that.
But they are still around, so it served them well, apparently.
That's how it works.
Evolution has no will, purpose or path, only traceable history.

>>9078698
It would be energetically sensible though. Isn't evolution about optimization, to most extents?

The official YouTube account of Reddit

Psychology. Even the professionals don't know what they're doing, but EVERYBODY has their own pet theories of how people work

>>9078269
This beg the question, why the fuck do you browse reddit?

By design, reddit is about attention whoring as much as you want. If you do not want to deal with attention whores then get out of reddit, facebook, instagram and similar social networks. There are so many different chans online that it makes no sense to use a typical social network. That is like eating soup with a dildo and then complaining that there is a dick in your soup.

Biology. So many people conflate biological sex with gender, and those who don't will claim that only XX or XY exist
