hey guys, im trying to figure out how to approach a 2.5d packing factor problem of sorts and trying to see how we can. How many credit cards could you throw into a pool, or lets simplify it and say what would be the packing factor of credit cards in the presence of gravity (hence mostly aligning the cards to have their largest side face up).

@ACuriousMind how would distance from camera be figured into that term though i guess is my question

juggernaut insurance companies*

The whole incentive and punishment structure of mortgages for example makes no sense for individuals, if America wasn't leveraging it's future monetary supply to create mortgage funds it wouldnt be sustainable in any capacity. Mortgages make sense for a business which can run a portfolio of properties to weather dry spells

Mutual aid societies collapsed into juggernaut societies, broad public markets detached from anything except self proliferation of a corporation, and you could eventually get people to even buy their houses like how a asset ownership business would want to financially structure it

@ACuriousMind this is a very effective way of introducing ideological shift, basically the balancing game of mercantilism greed with financial longevity and growth was only a small part of how society worked. By getting a "capitalist" culture accepted you created the consent to financialize all of society. This creates a bunch of new pathologies that you can create consent for under the guise of profits/returns

Which actually is why I initially started looking at this, I wanted a "lensing" mechanism that allows for you to look around an object/shape, but the GR aspect of it left me having a hard time understand how to control the manipulation.

yea, its a mechanism to look around something I suppose

@ACuriousMind so is this more of a generalized lensing equation, in the sense that it also describes traditional optical phenomena, or is it still just structured kind of mathematically like GR lensing sans the physics

@ACuriousMind the coefficient here was the confusing part for me btw, it causes some major localized warping but you're saying its just a fudge factor for physical effects right.

@ACuriousMind imo the term capitalism itself is kind of an interesting piece of manufactured consent. It was never used by Adam Smith, and was actually a term made by socialists (Louis Blanc). Before that "commercial economics" applied in an important but limited sense to describe a large family of market dynamics that occurred in what i call a communitarian producer society, but there wasnt this "everything for sale" culture that "capitalism" takes on. The word itself is a social trap

i expect that's technically done to allow for it to be better performance on video

just swapped overwriting img with imagecopy to return the copy

@ACuriousMind oh that was actually my only edit to actually make their code a little easier to mess around with

the visual effect seems reasonably approximate but it definitely doesnt scream physical to me either

hmm, youre right mathjax hadsomething right

no codeblock support =(

    if (lens >= src):

I had a bit of gravitational lensing code I was trying to understand but I actually never got to do more than special relativity so I was wondering if someone could help me break down what's going on and a bit of relevant reading (especially to help me figure out if this is an approximation)

Howdy folks, been a while

theres the name i was looking for

@Slereah is that from some gauss divergence thm shenanigans

hey guys, is there a nice way to think about faraday cages based on antenna EM diagrams

feeling European for the first time. Water pressure has gone to almost 0 today so I busted open that jar of mineral water

but how do you take the magnetic ffield produced by something like a solenoid and compare that with the magnetic forces characteristic of magnet. Like there should be some kind mass related term for a magnet shouldnt there, but you just see people throw out "this neodynmium magnet is ~1T"

curie temp

or was it called curie temp

@ACuriousMind well technically youd hit the curie limit before that most likely

Hey guys, quick question, practically speaking how do electromagnet strengths compare with rare earth magnets. I dont often see permanent magnets using a unit thats eaasy to compare with electromagnets, or they dont provide strength info per unit mass

@PM2Ring thanks, exactly what i meant

hey guys, is there a compressed notation similar to einstein notation using products (and tbh on that end is there a name for when you use the product operator, kinda like how summations are said to be in sigma notation)

So in that metric would the recurrence time be infinity, or would the concept of a recurrence time not exist (some kind of true divide by zero unrenormalizable /undefined error)

Hey guys, would an arbitrary macrostate of the universe have a Poincaré recurrence time or some analog of it? Could it be proven that such a term would need to be finite or infinite?

and the "compact dimensions" are just group operations that occur that aren't embedded in SO(3)

@bolbteppa i meant that expanding on the idea of large symmetries that are observed outside of standard 3 dimensional space (SO(3) symmetries), I was wondering if string theory evolved in a similar light. There were symmetries that extend beyond our standard understanding of 3d space to describe electron spin ( I believe that was SU(2) ), and hadrons for quark interactions ( Gell-mann shows up here). I was wondering if string theory is just another higher level group representation

@vzn the amount of fake things being shared is what really drives up the wall

aka accepting your alternative hypothesis of some correlation or etc

btw, rejecting the null hypothesis meant getting a p-value sufficiently small (below your cutoff) right?

man, ive changed computers twice since i made that bat signal photoshop for him, i wonder where that file is

he's missing the ACM signal though, so will he even answer our calls?

oh ok, so its a matter of scale invariance and renormalization groups

NCVS averages this to a defensive gun use::firearm incident ratio of 6 when it averages the15 major surveys where DGUs were reported source: Crime statistics: Bureau of Justice Statistics – National Crime Victimization Survey (2005). DGU statistics: Targeting Guns, Kleck

An often overlooked statistic that supports the difficulty in gauging this is Defensive Gun Use compared to violent crime statistics. Depending on your sources the number of DGU ranges from 600k to 3.5M cases a year. Journal of Criminal Law and Criminology, Kleck and Gertz, Fall 1995 is the 2.5M study and is one of the more commonly cited figures. An LA Times study reached the 3.5M estimate, and the Hemenway study cited by activists is an order of magnitude smaller vs most other major studies (outlier). This translates to a DGU:Firearm Incident ratio 2x and a 10x. Brandish DGU 92% effective

There is an incident that occurred in Oklahoma where a shooter opened fire and multiple people returned fire and he retreated. I was in the area I think in the Spring of 2019 and heard about it as current events from a resident in the area but dont know further details.

for a triplet of numbers, does them all being pairwise coprime mean that all 3 terms have no overlapping factors

any ideas about what i asked in terms of defining "a best fit" between a pair of arbitrary nonlinear functions

(to each other)

Hey guys, I was wondering if there is a golden standard for "the best fit" of two arbitrary nonlinear functions
