Euro anons, can you tell me a bit about your respective university systems?

>Difference in administrative culture
>The best Universities of different countries

(e.g. In America, MIT loves foreigners, but my home uni prefers americans)

feel free to tell some stories too.

Somewhere out there, that unit exists.

because this

what are, currently, the largest two WHOLE numbers that can be divided by each other to give, up to a point (decimal), an equal value of pi? note I know it will always just be an approximation.


x>221/71
x<22/7
x>???
x<???

question:
Does man know an accurate formula method of finding larger and larger whole numbers that divide more accurately "into" pi?
or are such whole numbers only 'found' by analysis, through other formulas ie. BBP

>but if you worry too much about mathematical rigor you end up massively obstructing progress

Yes and 1=2=π=e=α=√2=-1=0=∞ because fuck worrying about the details.

>which have all been experimentally verified. If you think all of those predictions were just due to luck, then you probably have brain damage or something.

Hell, dimensional analysis is literally "Lets play alphabet soup with symbols and see if the results check out" and occasionally comes out with the correct results. Anything that comes from such hand waving, whether be dimensional analysis or perturbation, comes out of pure luck.

You remind me of this.

i am really feeling like there is no way in hell that the units check out on that...

and can you attempt to explain gravity vs entropy?

hey i'm working on some differential and partial equations, and was wondering if there's a program that i can use to map out 3-d equations and do everything else i haven't learned yet. anything off pirate bay is a plus cuz i'm not paying for shit. inb4 lurk moar. i'd rather deal with the hate and come here first.

Pic unrelated.

What is the best STEM field to go into nowadays?
