topography engineer student
I feel like we're not studying shit here , just geodesy and other crap satellite detection and other useless shuiit , I regret doing topography
am i a real engineer /sci/?
>>8590253
fuck and i had a very high gpa for you americans
I couldve been doing mechanical engineering or electric engineer ing but no , i chose topography since there are only 60 places in the whole country so work is guaranteed

I took Calculus I-III almost 10 years ago. Made an A in it. I since forgotten all the Calculus I know but will need the computational aspects for graduate studies.
What is the quickest way to get a review? I am looking to get the most of out the time I put in.
I narrowed it down to:
Khan Academy, MIT OCW, OSU's Coursera Calculus videos.
Which one should I throw myself into?
>>8590103
Fucking figure it out. You already learned it. Learn it again
>>8590110
I'm leaning towards Khan academy cause he gets to the point quicker. MIT OCW will probably be good when I have more time to invest in it.
>>8590103
Khan Academy, srs
How do we make education appealing to everybody /sci/?
We have access into a plethora of information about almost anything on the web if you look hard enough but why does the majority (particularly the middle-class and below) choose to rather spend their time obsessing over celebrity drama and television? How do we fix this? Also, why are there still people who choose not to make their resources available to everyone? I think that as human beings, helping our fellows should make us feel nice and allow us as a society to advance faster. But why does the air of competition still dominant in our world? Is competition against our own kind really the way to go?
Your position implies that everybody needs the same level of education.
Ultimately, they do not.
>>8589936
I'm not saying that everybody needs the same level of education but more on raising their desire to be more educated, people are literally rallying because their mcjob is being taken away from them by robots all because they couldn't for the life of them, find the desire to git gud on anything that's not minimum wage tier
have less smug bundle of sticks LARP as scientists
Could a true hermaphrodite (with functioning testes and ovaries) impregnate themselves?
>>8589786
Just try it yourself, OP.
>>8589786
if they produce sperm and egg cells and have a uterus for the egg to attach to they could fertilize themselves but a person that genetically fucked probably could not produce viable offspring
>>8589796
>implant functional uterus in a man
>he fucks himself to pregnancy one way or another
A bit of a cheat but it's likely it might actually happen and not in the far future.
How did they make the first magnets?
So I understand that magnets are made by using powerful electromagnets to magnetize the molten metal as it cools but powerful electromagnets require lots of electricity, which in turn requires powerful magnets to generate in a plant. Thus a paradox.
How did they make the first magnets?
How did they make them more powerful, in other words, how do you make a stronger magnet from a weaker one?

It's fucking magic, dude. Don't try to think about it.

https://en.wikipedia.org/wiki/Magnet#Magnetizing_ferromagnets
is this what you're looking for?
there's more than one way to magnetise/increase strengh of a magnet.
stroke two weak magnets and you end up with two stronger ones.
>>8589556
magnets can form naturally sometimes
If you were to go to the North or South Pole and stand directly on the Earth's axis point (I'm talking like directly on top of) and jumped, would there be any difference? Would twisting your jump in either direction make any difference? What I'm getting at is would gravity effect you the same way as it would if you were standing at the Equator?
Thank you for your time and patience if you choose to answer.
A magnetic field is not regular dofus.
>>8589515
Sorry dofus here, don't follow? A short explanation please? I understand that gravity created by the Earth's mass would be consistent regardless of location. I was just curious weather or not a change in position relative to rotation would make any difference?
Has it ever been tested?
>>8589497
you wouldn't be able to jump as high because of inertia you don't have at the poles but the mass difference at the pole and equator is pretty much negligible
Earth's equatorial diameter is 7,926 miles (12,756 km), but from pole to pole, the diameter is 7,898 miles (12,714 km) — a difference of only 28 miles (42 km).
How do you make something out nothing?
Explain that /sci/ ...
>>8589337
Nothing doesn't exist.
Therfore something didn't come from nothing.

Amen, amen, amen.

How do i get better at da maths??? I dont suck at math, i'd say im average. But i want to get better.
work harder
spend effort making sure you understand stuff instead of memorizing how to do particular sorts of problems
make sure you understand everything you've learned so far. emphasis on understanding.
>>8589279
Read Gelfand's books, solve the problems.
>>8589289
understanding a concept doesn't necessarily help you remember it. You need both understanding and memorization.
Otherwise you'll know how to use an equation or derive it, but when it comes time to need the equation you can't remember its exact form.
You will instead get the Mandela effect and end up with an equation from your inexact memory that feels right to you, but is actually wrong.

It's easy to confuse yourself with this shit but it's quite simple.
All that the ramanujan summation stuff, cutoff and zeta regularization does, is look at the smoothed curve at x = 0.
What sums usually do is look at the value as x->inf.
It's just a unique value you can assign to a sum, really they have many such values.

>>8589432
wtf is a smoothed curve?

i hear alot of people praise Grothendieck
but i don't know much, can someone explain to me what the hell this man did to get alot recognition?

he made category theory actually slightly useful
Why is NASA so fucking retarded?
They're more interested in fucking stupid rocks that are only useful for mining, and they wouldn't have began working towards sending humans farther into space if it wasn't for the public raising so much awareness for Mars.
Also, why the fuck are they still working on aeronautics?
>>8588426
They should try and get to Europa. Fuck Mars, it's boring.
>>8588434
Best place to start a colony to get further into space tho
>>8588426
>They're more interested in fucking stupid rocks
I'm quite certain it is only you, projecting your sexual fantasies onto a dispassionate agency. Please try to convince me NASA wants to have sex with rocks.
Hi, I'm making a collection of mathematics textbooks. Would like to know if any of you have other collections that I can download to add to it.
I already have /sci/ collection of books and the following from TPB: "MATH MATHEMATICS BOOK COLLECTION" , "Dover Mathematics Book Collection" , "Mathematics Book Collection - Diophantine".
I'll put this collection for download when it's done
>>8588358
libgen.io has all the books you want may as well archive a bunch in case it goes down
I recommend you add:
-Algebra: Chapter 0. by Paolo Aluffi
-Linear Algebra Done Right by Sheldon Axler (actually all of Axler's books)
-MIT's "book" (coursenotes) on Mathematics for Computer Science http://courses.csail.mit.edu/6.042/fall16/mcs-ftl.pdf
-Advanced Calculus http://www.math.harvard.edu/~shlomo/docs/Advanced_Calculus.pdf
Plus all the texts listed here in this 3 part series (mainly Springer books) https://www.quantstart.com/articles/How-to-Learn-Advanced-Mathematics-Without-Heading-to-University-Part-1
I've also recently started archiving stuff because it tends to disappear forever these days. I prefer a physical copy to give the author money and save my eyes but some are priced ridiculous https://www.amazon.com/Calculus-Analytic-Geometry-George-Simmons/dp/0070576424
>>8588514
There a bunch here anon.

Hello.
What kind of programs would do a lot of floating point math?
I just upgraded my CPU and read that the new one can do FP way faster.
Went from Phenom ii x4 to i5-6600.
Try Prime95
>>8587522
Ah thanks.
>>8587522
primes are intigers...
