A thought just occurred to me: How does one calculate the median of an arbitrary set of complex numbers?

Haven't thought about this, but here's an idea that at least works as expected for real numbers. The median is the center of mass of those z that minimize \sum_{n=1}^N | z - x_n |.

R.O.S.E(realization of sieve of Eratosthenes) have mod(x,Po)/Po which is error item for count prime number where zero are divided into Po<x part equal to Po>x part (from all over view)for every zero of zeta function(Po is all combination of product of prime number less and equal to x^1/2), from Pascal triangle can see it symmetry at x=1/2(take two end point of line at bottom of triangle at 0,1), happen with Bernoulli number and moment of zero together , zero of zeta function Po<x part range from 0 to 1/2 (total of prime number in upper limit of Euler product at x^1/2)and equal to Po>x part mean 1/2+1/2=1(total of prime at x^1 for upper limit of Euler product) imply prime number theorem is true(zero inside 0<x<1 strip), more over from R.O.S.E p less and equal to x^1/2(without e in x^(1/2+e)) for x=p^2(for example at 2^2,3^2,5^2) , imply zero exactly right on line x=1/2, for x not equal to p^2 can fit in this structure(for example pi(5)=5*1/2+1/2=3) imply Riemann Hypothesis is true.

Countless numbers of physicists continue to insist that phenomena such as spherical collapse / star collapse are dictated by Newtonian gravity. Despite GR and the Schwarzschild solution being a century old now, folks continue to talk about gravity as a real physical force, instead of a manifestation of Spacetime curvature. Very strange! For example, star/spherical collapse is dictated by the matching of the interior and exterior Schwarzschild metrics:

+Mani A. Since I wrote the above comment, I tried out mathjax. For a small amount of math it is OK. But for a lot of math it becomes unacceptably slow. I'm using iceweasel, the Debian port of Firefox, since Google dropped support for Chrome.

|| MATHEMATICIANS BRIDGE FINITE INFINITE DIVIDE ||

A surprising new proof is helping to connect the Mathematics of Infinity to the physical world .

Mathematicians Ludovic Patey and Keita Yokoyama have found a bridge across the Finite Infinite divide , helping at the same time to map this strange boundary .

How is asking someone if they have an original publication allowing further reading on the topic "responding poorly"? Obviously, you are an internet troll, not a mind reader. I asked a logical question about a topic I simply want to know more about, and didn't deserve to have my integrity questioned by a childish provocateur.

I have no connection to the first commenter, LOGIC FAIL.

"Cause precedes effect; extempoproximally to its permissible effect...." Quite full of ourselves tonight in our refudiating malapropositions, aren't we?? Sarah Palin's neologisms didn't make her sound very smart either. Besides lifelong issues with logic and reading comprehension, she's quite good at picking arguments over topics she has ersatz knowledge about for attention too.

I hope your need to be 'drama queen' and 'tone troll' for the day was satiated, while the rest of us just who want to talk about math can get back to business, Mr or Ms. wool.

My question to the OP still stands....where can I read more about this topic in the academic math literature? I do not have online access to "Quanta Magazine". If that's not possible, a simple "I don't know, I'm just reposting the article" will suffice. Thank you!

+Ikjyot Singh Kohli​​​​​ Sorry, not sure to understand. Do you refer to folks or to physicists? :-) Also, I assume that it is the exterior metric that describes the collapse and it is more generally reported as an effect of GR gravity and Einstein relativity: where the inward attraction starts, deviating from the pure Newtonian orbit... Why are you concerned with the matching of the interior and exterior metrics? E.g. From Wikipedia, that's a coordinate singularity (nothing happens at the event horizon in GR theory), a lot of physicists do discuss about it in relation to the firewall paradox, but that's another (still unclear) matter, where quantum gravity is more relevant than GR... What am I missing? :-)

One thing about the law of identity is that it can make things redundant when it is isolated from its family of Ascending Meta-Hermetic Formulas. Under the Law of identity since it is the law of "look alikes" or "copies" then its interpretation of multiplication logically leads to Multiplication being the repeat of Multiplicants relative to Multiplier's value. Thus the law of identity sees the repeat of multiplicants as its only representation. In Ascending Mathematics it is not the redundancy but its originality. For the Multiplier called 5 we know that five is the mid point in the Decimal system and it is connected to the Divine split by 5(it self). Thus only two simple factors are needed when 5 is a multiplier...1) 1/2 and 10. Every Multiplicant is also a Synergy Value. The synergy is halved and multiplied by 10. Notice the digital variable value is 1/2 thus 1=1/2 when 1 is a digital varable. Hence 1/2 times 10 is the universal answer to 5 as a multiplier in Decimal system.
Polar formula is when a negative and positive number of the same magnetude is equated and thus its synergy value is double that of one side. That is why in a general formula of -A=+A the synergy value -2A and +2A.

Ascending Algebra and Ascending Arithmatic are two different poles that merge as one mathematical element. I will use "x" and "y" as elements in my example.
Demensions Define in Ascending Mathematics is Different Base System Space. Different space have different patterns and thus different space is defined by different base system. If Different Axis have the same base system then they are of the same Demension if they are different base sysem then they are of different demensions.
In the Future I will use D instead of X and Y to define the axis because there are infinite unique types of Axis(Demensions). So for x I will use 1D and for y 2D for example. Also we leanred that we can use digits and numbers as varables besides using x and y.
