i have done two real iq tests and the result is around 125. Now i just realize that a lot of "bad luck" in exams and competitions could actually be a result of inferior brain power.

Do you still remember the difference between Rieman and Lebesgue integration after graduation?
You can admit it here, this is a safe space

With the Riemann integral you had upper and lower sums and they had to converge to the same value

I don't really remember the Lebesgue integral but I recall there was something wonky with finitely-valued functions

there is a difference?

Well whenever both are defined, they take the same values so...

>area between two curves above x-axis is positive
>area between two curves below x-axis is negative
Makes sense

>area between two curves that covers areas above and below the x axis is only positive

Somebody explain this shit. I understand that all areas are non negative or positive, but computing the integral for an area above x-axis is positive, below x-axis is negative, how does the integral follow those rules but still solves areas that expand across both quadrants?

>negative area

>>
>>8619381
No, the area between two curves is not affected by where they are on the Cartesian plane. Taking the integral of f(x)-g(x) instead of g(x)-f(x) is the only thing that changes the sign of the integral.
>>
>>8619394
The integral will come out negative if the area is only below the x-axis.

You're marooned in your spaceship with 5 minutes of oxygen left when some ayys hail you.
Through ayy magic they contact you and say they can prepare a room for you on their ship.
But they need to know what conditions, atmosphere and such the room needs to have for you to survive.

What do you tell them?

If you've got ayy magic then can't you just scan the contents of my air tank?
>>
>>8619369
Assuming they are friendly and don't want to keep me for experimentation, I would tell them to fill the room with air composed of 75% Nitrogen and 25% Oxygen. The atmosphere would have a pressure of 15 pounds per square inch. Provide a hole for getting rid of waste products and reclaim water. Assuming that they can fabricate certain compounds or atoms, I would tell them to provide twenty gallons of water with some multivitamins.

I'm studying psychobiology ( psychology degree in the university of Barcelona ) and the more I study it, the more I think something/someone created us. Everything is so complicated and perfect that, fuck off, it's almost impossible.

Have you ever wondered if there's really a ''''god'''' that created us?

>Everything is so complicated
>and perfect that
if by complicated you mean you don;t understand it then how can you say it's perfect. Surely understanding is required to judge something as perfect?

I present this as proof it is not perfect because you did not understand this, which means you are not perfect, and your deductions are wrong.

If you think everything about human cognition or the human brain is so perfect, clearly you haven't been studying psychology for very long.

I'll try to explain myself. I can understand the logic into mathematic, and why you have to do an operation in one way or another. but as example, when I see formulas an there is a exponential, why? how do you know you have to elevate something to a determined power? I understand it in geometry, but once I'm aout of that field, I can't make any sense of it.
what I really want to know and my poor english does not let me explain is that, there is logic at the bottom of mathematical operations and formulas, but I can't see it. how do I undertand this kind of things?

>>8619276
Usually a field has two defined operations. Then you can prove that other operations follow from them.

For example the reals have two operations, addition and multiication. You can use the trichotomy law to get division and subtraction. You use multiplication to get to exponent, etc.....

The logic behind it is that you unfurl definitions to more and more basic logic until you get back where you started.
>>
>>8619276
>when I see formulas an there is a exponential, why?
Because we want to.

>how do you know you have to elevate something to a determined power?
We know this if when we simulate solving the problem in our mind, at the end we get a solution.

> there is logic at the bottom of mathematical operations and formulas, but I can't see it

There isn't much logic to it. For every problem there are a billion ways to solve it so you just need to start simulating solving it in your brain until something clicks. Then you write that down.

>how do I undertand this kind of things?
By solving problems.

Faulty logic senpai. For starters women haven't been able attend university for that long, for example Cambridge didn't admit women until 1947. Second you assume that Nobels should be distributed amoung women and men equally, why? It's completely plausible that women have interests laying in fields that aren't science.

Engineers, how many credits did you usually take per semester? The internet tells me it should be around 17, but I seem to need to take around 20 this semester to stay on track. (I've never fallen behind either).

i took 16 every semester but my last where i took 12. did 6 credits the first two summers and did internships my last two.

also dual enrolled at my local community college because they had 3 week, weekend classes which allowed me to blast through a bunch of bullshit humanities courses. look into something like that near you because goddamn am i glad i didn't have to put up with that shit for a whole semester.

Okay either that is some euro bullshit or your credits are worth less than ours. Post an example of a 30 credit courseload.
