Not as bad. When I was 15 I read Calculus made Easy by Martin Gardener over the summer, and ended up skipping Calc 1 and 2 and just went straight to Calc 3

>>8787956
did you memorize all of your identities?


That's really the secret to calc 2. Being able to do the algebra and simplifications. The actual integration and derivatives are easy.

Also you're only in the first few weeks of class, it will get more difficult and quickly.

>>8787956
calc III is easier than calc II

"Fermtas last theorem" by Simon Singh is really fun to read!

That's a great book. So is Code Book (by the same guy)

Personally I'm looking for more mathematical/science-y books. Pic related is good although not as much as my opening post

>bedtime reading
>math

You honestly read math books during bed time? Wtf?

Fuck that noise. Reading math is the worst thing about being in this field. I like doing math. If I am to do anything math related during bedtime, I'm going to be thinking about something or trying to sketch a proof of something.

Fuck reading math.

Also, I've read that light that gets stuck on the edge of the ergosphere trying to escape outwards going the wrong way is infinitely redshifted. Why wouldn't light leaving the ergosphere be infinitely blueshifted, like it's expected to be near the inner horizon of rotating and charged black holes.

shameless bump, first page is filled with shit threads anyway

>>8788090
Ya'll sure about that nigga? I'm pretty sure that objects in the ergosphere orbit large black holes in relatively short amount of times, as seen by outside viewers. Also I would imagine the amount of time dilation you see an object experiencing would depend on the angle you are viewing them at, and objects that are moving towards you in the ergosphere should have clocks that are possibly ticking faster than your own.

It's the fact that our current status quo, constructous apparatus, what has gotten humanity to where it is. It will not get us much farther. We need innovation, and we need it now.

>>8787441
We're only human, it was bound to happen but there's hope.

In faster words, I might have been exposed to 15 - 30 seconds of garage CO to turn it off from at worst, 5 minutes of running.

I haven't passed out or had any trouble breathing. Will I be fine?

You'll be alright besides the minor loss of ~30 IQ points.

>>8785983
CO is not dangerous, CO2 is though.

nofap is literally just meme tier reddit broscience, there's nothing to it

From personal experience, it's because your dick gets tired and you find average women ugly because you are staring at hotties all day.

I don't think it causes permanent damage.

Rocket Science.
Except for the suicidal ones.

electrical definitely has the least women, so that one

Environmental. I started out as one but realized that no one respects it, and most people who get a degree in environmental engineering don't work in their field.

Why would I waste 3 hours taking a test for 17-18 year olds, when I could take multiple online IQ tests in that same amount of time?

first one is easy by noticing that integrating I_n - I_n+1 is the same as integrating u^2/(1+u^2)^n+1, which you can do by parts as u and u/(1+u^2)^n+1

the second part you just gotta iterate the formula

>>8775614
Looks easy enough

I did the Oxford Physics Aptitude test when applying and that was easy as shit, so the Cambridge maths one probably is as well

It's mostly 16-17 year olds doing the test, it's done like 3/4 of a year before graduating highschool

Yes. Yes I am. If they pull it off then we are officially living in the future.

>>8774571
It's going to explore you fucking idiot. The duture is not now, and people evolved to live on Earth, not in space so we don't belong there. Deal with it.

>>8791187
you can only deduce g1 and g2 are equal if you're actually covering all the set
if there's a point that f doesn't reach, then you can create different functions by making them take a different value at that point (one of them can take 0, the other 1)

>>8791200
Can you show me a trivial example (spelled out for me)? I am almost following.

So do you mean every object in the entire category has to have arrows, or does it mean only every object in the category Z ( in my example) has to have arrows mapped to it?

>>8791187
En epimorphism is simply a function [math]f : X \rightarrow Y[/math] such that for any two functions [math]g_1,g_2 : Y \rightarrow T [/math] to some testobject T. we have that [math]g_1f = g_2f \implies g_1 = g_2 [/math].

Now if [math]f[/math] is surjective, then [math]f(X) = Y[/math] so this means [math]g_1, g_2[/math] coincide on all of [math]Y[/math], meaning [math]g_1 = g_2[/math]

His is the right way to do math but there is a quick and dirty way to translate math from his version to the version accepted by the (((mathematical establishment))).

Find theorems using his theory.
Translate to (((their))) theory
Publish and get (((their))) money.
Repeat.

They say Perelman did this with his legendary proof but didn't accept the prize because a good Christian does not take money from (((them))).

>>8791007
does he teach math until calculus or what?

>>8791015
He teaches all sort of shit.

Number theory, integral calculus, geometry, trigonometry, algebra, topology. analysis. All has been covered.

There are gaps though. He hasn't finished his series and many topics have only been covered at an introductory level but if you already know modern algebra, and then you watch his introduction, you can translate the rest into his theory pretty easily.

>I just wished everything wasted energy and had more latency
why?

fucking die you stupid normalfag, I hope this won't become a trend because of you brain dead normies who have no idea that shit like wireless audio is wasteful and of shit quality

I can't imagine that pacemakers and computers would do well with wireless electricity

>how to prove theorems
you need a full math undergrad
the start is real analysis and linear algebra

>>8790493
I am CS major.
I can know real analysis is needed but what is in linear algebra.Its just vectors and matrices.

>>8790505
it would be wise to approach math in a more humble manner. linear algebra is relatively simple but not nearly as much as they make it look for non math majors. it is a very nice topic and you need to be able to use its tools very well for higher topics. using the correct book goes a long way, try Hoffman & Kunze

while I'm recommending books you can use Tao Analysis I for analysis
