Every number theory textbook I pick up assumes you already know number theory prior to reading it. I cannot understand the chapters/proofs fully and the exercises are impossible.
What are good number theory for retard guides? Not for Math Seniors or PhD students.
what kind of number theory are we talking about? elementary (baby's first modular arithmetic), algebraic (rings of integers etc.), analytic?
>>8492470
Baby's first exposure to number theory. I assume the one in your pic is good for baby's first exposure?
>>8492475
i don't know what your background is but i could recommend my own very first exposure which was Hungerford's 'Abstract Algebra: An Introduction', obviously it goes from an algebraic point of view but it basically starts with a chapter with the integers, does some modular arithmetic, goes onto the rationals and more general fields
'An Introduction to the Theory of Numbers' by Niven/Zuckerman/Montgomery goes further and is more purely number theoretic
Weil's definition of 'Basic' might be different than most people's
I'm an idiot.
To find the possible number of occurrences of 5 numbers (100,200,300,400,2) would you just simply multiple 100*200*300*400*2? Which would equal 4800000000 according to Google.
Thanks
>>8492394
occurrences of what?
>>8492400
anything, types of bugs, houses, etc.
Sorry if I'm not making myself clear
>>8492415
?
What do you mean by "occurrences of 5 numbers"?
Thanks
Can we talk grad school?
I just got accepted to Pharmacy School.
Are professional degrees even worth it these days?
Are any of you accepted/going to grad school? If so what disipline? Do you regret it?
>>8492195
I don't regret it cause I don't study shitty subjects

Thx for doing my homework :)
Hey /sci/ does anyone have a good intuition what differential forms are? I know how they are defined but I don't find its definition very illuminating. Inb4 it's the only thing that can be integrated over. That's not particularly helpful either
>>8491786
" muh intuition"
It's just PDE, [math] df = xdy + ydx [/math] or smt like that. If you do not get the definition, make some exercices.
>>8491786
The differential form of a function is kinda like the rate at which said function varies. At least, that's how I 'intuitively' think of it. Just keep in mind that this is rather vague and the actual definition is how you should look at it.
>>8491786
Draw a picture. The definitions describe the geometry. Don't start with definitions unless you know what they look like.
Is there a possibility that, in another region of space, ยต0 could have a different value than what we currently know? Either higher or lower.
The value of the permeability constant is a function of ฯ, so yes it will change if the region of space is sufficiently warped such that Euclidean geometry no longer applies.
>>8491928
>if the region of space is sufficiently warped such that Euclidean geometry no longer applies
I can't think of anywhere that conforms to that definition but I'm not an astronomer either, does such a place exist?

Scientifically, how many farts would i need get to the moon?
Depends on your initial position and velocity.
>>8491571
Standing still, either straight up standing in a field farting or maybe in a spaceship fuled with farts
>>8491574
you would need to store a lot to get to escape velocity

I have ADHD, I'd probably be a pipefitter instead of an engineer had I not gotten medicated as a kid.
>>8491369
fuckin hell. im 21, still no medication, and was a pipefitter during summer, after i droped from engineering school, kek, no lie.
so what are you taking and has it helped you?
>>8491381
>has it helped you?
brain lag
How were you feeling when you were medicated?
What inspires you? What inspires you to further your research? What facts about the universe motivate you?
I want to know how invested you are in the universe, the world you live in. No judgement to those who's profession is related strictly to the Earth or the sun, but you can be a geologist on Earth and still look beyond the stars. Hope it doesn't go too far into >>>/x/

How hard would you need to stomp someone's head in a curb stomp to kill them?

4 is necessary but possibly not suffient so that's wrong
How good are the 16 personalities test?
And no, no one wants to know your test result
It's got kind of a bad rep among "higher" psychologists.
http://indiana.edu/~jobtalk/Articles/develop/mbti.pdf
The descriptions are often seen as too vague and flattering, some people get a different result every time they take the test, and even among people who have a "stable" personality type there is little correlation as to how they perform in the field they're recommended. It's still fun though
I think there are other psychology tests that are more accepted among professionals, like the occupational personality questionnaire, The Hogan personality inventory, or the big five. And those tests don't really put people into categories, except for some interpretations of big five, it's mostly used to know how much a trait is present in you (for example how "open" you are).
But even then those tests are mostly used as indicative values.
>>8486030
>The Hogan personality inventory, or the big five
>none of them are free
feelsbad man
>>8486047
http://similarminds.com/bigfive.html
you can try that one if you want an idea of what the big five is about. Be warned though, the big five type descriptions aren't nearly as flattering as the MBTI ones, look at this one for example http://similarminds.com/global5/rcoei.html
