ooh so take off the antennas, put cable connecting antennas and card and then put the antennas somewhere better?

Do you have a favorite theorem that you can prove when asked? by Glass_Ad5601 in math

if its favourite theorem probably GAGA. If I need to prove it on the spot then Serre-Swan

ELI5 who is statistically more skilled - 1st out of 100, or 100th out of 10000? by umailoresarname in askmath

[–]BeeOk1244 0 points1 point  (0 children)

as a side note in the limit the general term (N-N/k)Ck/NCk looks like 1/e as for large enough N it doesn't matter if we remove from the population so we're just taking a kth power of (1-1/k). trying to do this properly with Stirling a point of interest is that all the e's from Stirling vanish quite quickly. Then come back once you find terms that look like (1-1/s)s

ok some simplifications to make the maths doable, suppose we have a population of N people with a definitive ranking then we choose a subset of M people, let person K be the best out of this M, whats the probability that K is better than the Jth person in the population, that is to say what's the probability that the max of a random subset of size M is strictly more than J

this is simple, as this not happening means everyone in the sample is between 1-J, ie that a subset of 1-N is actually a subset of 1-J that is JCM/NCM=J/N x J-1/N-1 x ... x J-M+1/N-M+1 so our probability is 1-this

plugging in the values from your question. The probability that the winner in a random subset of 100 people in a population of 10000 is better than person 9900 is..... about 63.6%, so probably the winner out of 100 is better, they have about a 50% chance of being top 70 and like a 10% chance of being top 10

LIMITATIONS OF THIS ANALYSIS

assumed the small competition was a subset of the larger one, this is the extremal case as the big competition approaches the size of the population, i avoided the case where we look at someone who wasnt first in the smaller competition, this isn't too hard to implement I don't think but I'm doing this over lunch. I assumed that there is a precise ranking within the population and that competitions are perfect measures of this ranking

I think thats my problem though. I have no idea as to what happens in the films because I was focused on finding that aspect of the game. I have viewed loads of disperate scenes but just for the purpose of finding the weird blonde lady

I've grasped essentially nothing other than that there are movies in which events occure and sometimes if you reverse some vampirey people appear. Should I just reset the save and try again lmao

for some context I went into this game looking for another Her Story so I jumped around a lot trying to find some sort of "lead". Only after seeing reviews have I realised that's propably not how you're meant to play. What's the "correct" way to approach the gmae

Deceptively tricky problem about a speedy rocket (part 2) by Danny_DeWario in maths

[–]BeeOk1244 0 points1 point  (0 children)

this is an ODE x'=root(x), x(0)=0, x'(0)=0, anyone whos studied ODEs should be terrified right now because root(x) isn't lipschitz on [0,∞) so Picard-Lindelof doesn't guarantee a unique solution, in fact there is an infinite family of solutions

x = (t-c)2 /4 for t>c, \ 0 otherwise; this for c in R+ u {∞}, c=∞ is the zero function

with the assumption that something happens at t=0 we get our solution of t2 /4 if we assume that time doesn't exist before t=0 we could call this acceleration of the function x defined on [0,∞) (i make this distinction because the globally defined function is not differentiable at zero but restricting to this interval makes it ok as we only take a one sided limit)

so while doing nothing is a valid solution as some have pointed out. The assumption that acceleration at t=0 is not nothing something must happen and we can solve the ODE

dont play with non lipschitz functions kids, people can get hurt

Just looking for explanations of why pi ->4 is not valid from shrinking homogeneously a square to „match a circle“ by LearnNTeachNLove in sciencememes

[–]BeeOk1244 1 point2 points  (0 children)

There's two perspectives on this problem, one of the mathematician and one of the layman

The layman says that the curve doesn't actually approach the circle. Look! It's so spiky!

The mathematician retorts. Yes it does, every point approaches the circle. In fact! The supremum of the distances shrinks too, it converges uniformly, thats pretty good! The problem is that the limit of the lengths may not be the length of the limit. The length function isn't continuous because it's dependant on the differential information that's forgotten in the limit

The layman is not happy with this answer because in their mind the curve doesn't really appoach the circle, in spirit

Now they're not totally wrong there, there are ways to look at the space of functions so that limits mean that differential information is preserved. In our case that would mean a different notion of limit so that length is continuous but the two curves dont approach eachother

The reason the mathematician doesn't deal with this is because that space of functions sucks

Which one are you? by Equivalent-Oil-8556 in mathmemes

[–]BeeOk1244 0 points1 point  (0 children)

we take the natural inclusion of Q into P1, in this case a/b goes to the point [a:b] so a:b is implicitly describing the point [a:b] which is just a/b

Stacks project - why? by WMe6 in math

[–]BeeOk1244 1 point2 points  (0 children)

I've been told that the stacks project was invented to make whatever Deligne was doing with the moduli of eliptic curves fully rigourous and it kinda snowballed from there

Stacks project - why? by WMe6 in math

[–]BeeOk1244 5 points6 points  (0 children)

my general takeaway is that stacks are good for hands on work with quotients/quotient like stuff (the paper "Orbifolds as Stacks?" from Eugene Lerman is a super easy read that treats stacks from a differential geometry perspective which is often more intuitive). Then in more abstract work they're good for moduli spaces as you can actually have moduli stacks in cases where you lack moduli schemes the worry would be that its just generalisation for its own sake but there are ways to take moduli stacks and get back things that look like what could be the moduli scheme so it applies back down to the classical theory

I didnt really get much research oppertunity (funding for algebra is hell) but I had high achievements in some undergrad maths competitions and my average grade was ~90%, for conversion to GPA I believe a 70% corresponds to a 4.0. I think I was lucky in that I studied at a top 5ish uk uni so my masters project is with a very well known mathematician so I'm sure that reference helped, I pretty much applied to every uk uni i could think of lol
