Hey, /sci/. Need your help.

So I am going to take the AMS test inot the coming weeks, but I need to be prepared for it.

The thing is, my teacher said there is no actual way to study for it and it is all application, but there must be a way to get some sort of foot in the door.

The test is a sort of mathematics based exam that will give you very complex problens and have you solve as many as you can in 90 minutes.

The only reason I am taking this and and tally giving a shit about it is because it "would be an amazing feature on a college transcript" when I apply to MIT.

Help me out /sci/, what can I do to study for the unstudyable.

Always been my dream to go there since I was a kid.

If not MIT, where would you recommend I go for a CompSci degree that isn't shit and easy to get into. Thinking of Stanford or CalPoly.

I don't know about CS.

Just make sure you put your heart and mind into that essay and make it the saddest sob story in the history of tear jerkers.

A pro tip is to start with you being a black turned white trans-race. That way you can still be white, but say that you were opressed and get those sweet, sweet opression points.

Wasn't there this famous mathematician who claimed that doing math while not on amphetamines for him was terrible or something?
He said that while on them he could look at a blank page and see a bunch of ideas and stuff.

So yeah, it probably does.

Hey /sci/

What music do you listen to?

Personally I'm all over the place as one genre never seems to fit in every situation, as in: self appreciating rap when exercising, 90s rock/alt when I'm having those feels, electronic when I want to relax, whatever Animals As Leaders falls into when the rest gets boring.

The leak dance song on infinite loop in my head when I need to stay focused.

ok sci, pls redpill me over having sex without any protection.

how dangerous are STD?
how easy is to get a girl pregnant?

how dangerous is to fuck your female friends instead of whores and sluts (this implies you'll try to meet always new female friends instead of paying for sex)?

hi, i wanted to ask /sci/ a question about linear algebra.

i'm new to this board, and i cheecekd out the /sci/ guide page (which was really good btw), but i couldn't find anything on linear algebra. my professor said that the book we will be using for linear is not very good, so i was hoping some of you anons could give me some linear algebra textbook suggestions.

i really appreciation any help given!

Okay. First off, I want to appologise for this ahead of time: English is not my first language.

Now I'm cross-posting this from /lit/ because I think this counts somewhat as a scientific problem, specifically in regards to the Species Problem:

So recently, I read Charles Darwin's On the Origin of Species. It got me thinking about evolution and how one species can change over time into another one. And I realized that gradients like that everything. AND THIS MAKES ME REALLY ANGRY! Why? Because now I find it hard to define anything. Take the image attached. I'm sure we can agree that on one side, it is blue, and on the other side, it is red. But at what point does red turn into blue? You can't mark off any specific line because at any line, the color directly on either side would be nearly identical. SO IF WE CANNOT DRAW A LINE, HOW DO WE DEFINE RED OR BLUE?

More relevant to the book, is the definition of human. You probably consider yourself to be human. You probably consider your parents to be human. And their parents. etc. But if we go back far enough, we get something that you wouldn't be willing to call human.

But let's say we do that in order. We keep going back a generation until we hit something that's not human. But we just called the child of this thing, human. And assumable, they'd be very similar things. So how can you justify calling the parent not human?

I DON'T UNDERSTAND GRADIENTS AND IT'S RUINED MY WORLD-VIEW BECAUSE I CANNOT GIVE ANYTHING CLEAR DEFINITIONS ANYMORE. HOW DO I DEFINE RED VS BLUE? HOW DO I DEFINE HUMAN VS NOT HUMAN? WHAT IS THE DIFFERENCE BETWEEN A TABLE AND A CHAIR?

Basically two things are a different species if they can no longer reproduce to produce viable offspring. So if we go back through time the point at which we can no long knock up a cousin on the Homo tree is the point at which they're two separate species.

>Intensive phototherapy is provided at an irradiance of 30 mW/cm2 per nm or more (430–490 nm).

How do I read this? Do i have to multiply it for the wavelength? Is it
30 mW/cm^2
or
30 * 460 mW/cm^2 (13.8 W/cm^2)?

Is it possible that how some believe the need for dark energy/dark matter is simply a result of us being wrong about the mass/temperature of the universe?
2 posts and 1 images submitted.

If we were wrong about the mass of the universe both dark matter and dark energy would change in quantity. Dark matter has a considerable amount of non-cosmological evidence behind it. So most likely it would stay in some new quantity (since dark matter is the largest component of the universe in mass). Dark energy's future would be more uncertain however. To be wrong about the mass of the universe tests of cosmology would have to be wrong, it is not simply assumed. If these tests were wrong then you couldn't trust the dark energy result until you rectified the problem.

The temperature of the universe (as in the CMB if that's what you mean) is measured not assumed. If that was wrong the CMB results (the most powerful test in cosmology) would be uncertain. If we were wrong about the temperature low mass dark matter like neutrinos could make a comeback.
