+Sameer Rajesh so what you are saying is that's it's not an actual value rather more of a primary I'd # in the directory of important mathematical ideas???

Pair correlation of nontrivial zero of zeta function
 
Mod(x,p)/p of realization of sieve of Eratosthenes for combination of prime equal and less than  x^1/2 of Euler product for (cos)>x part stay close Euler product divided by correspond prime number minus 1 which is total of reverse of combination of prime, combine with (sin)<x part can get nontrivial zero of zeta function, can see when gap between prime get bigger, then nontrivial zero get closer like Euler product (p-1)/p((21-14)>(25-21)).

For any combination NCR when N= (6n+1) or (6n-1), then the combination will be divisible by N for the any value of R other than the value of R= (0 & N) 

Sorry for the above matters only prime numbers are perfectly divisible by N.

Math

Discussion  - 
 
Real analysis is a branch of math that takes a closer look at the concepts developed in introductory calculus: differentiation, integration, limits, and infinite series. If you really want to fully develop these ideas, then you might start asking yourself what structure you need on your space to understand these operations. What ends up being crucial is a sense of nearness (a topology https://en.wikipedia.org/wiki/Topological_space), a way to measure distances (a metric https://en.wikipedia.org/wiki/Metric_(mathematics)), a way to measure lengths (a norm https://en.wikipedia.org/wiki/Norm_(mathematics)), and a way to measure angles (an inner product https://en.wikipedia.org/wiki/Inner_product_space). This is all roughly speaking of course, but with all of these structures together on a (vector) space, it is possible to develop a fairly full theory of differential calculus of several dimensions on the real numbers.

Notice that in the above Venn diagram that most of the spaces are a subset of one of the others. This happens because each smaller space induces a property on the larger space. That is, if we start with an inner product space (a vector space with an inner product), then we have a “natural” way of writing a norm using that inner product. So an inner product induces a norm, a norm induces a metric, and a metric induces a topology. However, not every topological space is a metric space, not every metric space is a normed vector space, and not every normed vector space is an inner product space.

Pascal's Theorem

If a hexagon ab'ca'bc' is circumscribed to a conic, the straight lines p, q, r which join the three pairs of opposite sides are concurrent.

Branchion's Theorem

If a hexagon AB'CA'BC' is inscribed in a conic, the three pairs of opposite sides intersect one another in three collinear points, P, Q, R.

There is an excellent study of how Pappus of Alexandria reduced the problem of the duplication of the cube to the finding of two mean proportionals (along 2a = (a + c) + (a - c), I venture to imply):

when (2^n - 2)/n is perfectly divisible then the number n may be prime number. 

The above statement is derived from the raw of combination number where 
For any combination NCR when N is prime number then the combination will be divisible by N for the any value of R other than the value of R= (0 & N). The summing of all the combination number except (R=0 & R=N) will be divisible by N. 

The above statement will fail when for non prime numbers N' the some of its combination number N'CR form a divisible number of N'. 

I am posting it for discussion purpose. I have no firm Proof to prove the statement is right.

calculate nontrivial zero of zeta function from realization of sieve of Eratosthenes.
 
From realization of sieve of Eratosthenes can calculate total value for mod of combination of prime for <x and >x part, and from Euler product for prime equal and less square root of x can get nontrivial zero of zeta function, at difference of x get different value, take average can close to real value, for example 1597^2 get 14.1465, 10009^2 get 14.3365, 19997^2 get 13.909, add 3 number together then divided by 3 get 14.13, actually value for first nontrivial zero of zeta function is 14.134725 which correspond to 2, for second zero 21.022(correspond to 3) repeat same process, and so on for rest of zero, each zero only one prime difference, and trivial zero are reverse of nontrivial zero. is possible Riemann calculated several nontrivial zero from same method use here.

+Brett Hawkes Only in your ignorant imagination is Pi an algebraic number. The fact that pi is transcendental was proven centuries ago and hasn't been disputed since. If you think that you're in the position to challenge a fundamental proof verified by a high mathematical society then you're a very delusional and conceited motherfucker.

Everything you wrote blatantly shows that you do not understand what a transcendental or algebraic number is even after looking it up just now. And everybody knows what transcendence means outside of math you idiot! The fact that you obviously assume that the average person doesn't further shows how full of yourself you are.
The fact that you think that entering that horseshit irrational number into a calculator could in some way suggest that Pi is algebraic further goes to show how little you understand what an algebraic or transcendental number is.

Quit embarrassing yourself with your bullshit and go educate yourself so that you'll cease to be a fucking idiot.

Awesome blogpost on John Conway
 
Article très sympa sur John Conway.
The long read: John Horton Conway is a cross between Archimedes, Mick Jagger and Salvador Dalí. For many years, he worried that his obsession with playing silly games was ruining his career – until he realised that it could lead to extraordinary discoveries

Junction is the study of combination and permutation. This study enables to find combination and permutation in an effective way. In this sight I have described the convenient method to permute a permutation with formula and its proof.
