This document discusses a method for determining if Goldbach's conjecture is true for a given even number 2n. It presents a formula (formula 3) that checks if two prime numbers p and q exist such that their sum is 2n. The formula uses sine functions and multiplications to test all possible combinations of p and q between 2 and 2n-2. An example application of the formula in a computer program finds a solution, providing evidence for Goldbach's conjecture being true for that even number. The document concludes by stating the remaining step is a formal proof that the formula always produces a valid q.
In this work, the author builds a search algorithm for large Primes. It is shown that the number constructed by this algorithm are integers not representable as a sum of two squares. Specified one note of Fermat. Namely, we prove that there are infinitely many numbers of Fermat. It is determined that the first number of Fermat exceeding the number 2 1 4 2 satisfies the inequality n 17 .
Derivation of a prime verification formula to prove the related open problemsChris De Corte
In this document, we will develop a new formula to calculate prime numbers and use it to discuss open problems like Goldbach, Polignac and Twin prime conjectures, perfect numbers, the existence of odd harmonic divisors, ...
Note: Some people found already errors in this document. I thank them for reporting them to me. Though, I am able to solve them, I deliberately want to keep these errors in the document for the time being to discourage error seekers from reading my papers. These people look at the details while missing the bigger picture.
Yet another prime formula to prove open problemsChris De Corte
In this document, I derive again a new formula to calculate prime numbers and use it to discuss open problems like Goldbach and Polignac or Twin prime conjectures.
The derived formula is an interesting variant of my previous one.

Analysis of algorithms is the determination of the amount of time and space resources required to execute it. Usually, the efficiency or running time of an algorithm is stated as a function relating the input length to the number of steps, known as time complexity, or volume of memory, known as space complexity.
Now we have learnt the basics in logic.
We are going to apply the logical rules in proving mathematical theorems.

2-Contrapositive
3-Proof by contradiction

The 1741 Goldbach [1] made his most famous contribution to mathematics with the conjecture that all even numbers can be expressed as the sum of the two primes (currently Conjecture) referred to as “all even numbers greater than 2 can be expressed as the sum-two primes” (DOI:10.13140/RG.2.2.32893.69600/1)
Finding and sustaining Alpha is the wet dream of some mutual fund managers. If their investment approach would result in a sustainable alpha then it would mean that they generate money for their clients despite the fact that the stock market goes up and down.
The Collatz conjecture can be summarised as follows: take any positive integer n. If n is even, divide it by 2 to get n/2. If n is odd, multiply it by 3 and add 1 to obtain 3n+1. Repeat
the process indefinitly. The conjecture is that no matter what number you start with, you will always eventually reach 1.
The answer to the question whether there are any odd perfect numbers is one of the unsolved problems in mathematics. In this paper, we will show that there aren't.

Where and why are the lucky primes positioned in the spectrum of the Polignac...Chris De Corte
The goal of this document is to share with the mathematical community the test results of my twin counting formula. The focus of the test is twofold: first we test if the formula seems to be valid for different offsets in twin primes. Second, we try to understand if we can derive some properties in the results.

Approximations in drawing π and squaring the circleChris De Corte
In this document, I will explain how one can theoretically draw π (pi), up to any desired accuracy, using only a ruler and a compass.
Afterwards, I will show the easiest way to approximate the squaring of a circle.
I am well aware that “Carl Louis Ferdinand von Lindemann (April 12, 1852 –March 6, 1939) published in 1882 his proof that π (pi) is a transcendental number, i.e., it is not a root of any polynomial with rational coefficients”.
The reader is warned that following this, it should not be possible to draw π hence to square the circle.
In this document, I will explain how one can quickly and easily trisect an angle with reasonably high accuracy using only a ruler and a compass.
As one will see that the used methods will result in a trisection with unnoticeable error by the naked eye.
I am well aware of Pierre Laurent Wantzel’s proof from 1837 that trisecting an angle is mathematically impossible.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

1. How to determine Goldbach’s q’s where 2n=p+q
The starting point is an earlier derived formula to check if a number is prime or
not:
ିଵ
ܲሺ݊ሻ = ෑ sin ቀ
(formula 1.)
ୀଶ
ߨ݊
ቁ <> 0 => ݊ = Prime
݅
Goldbach’s conjecture states that every even number can be written as the sum
of two primes.
We can agree on following convention:
2n
q
p
every even number
prime number greater than 2 (and q≤p)
prime number smaller than 2n-2
With: 2n=p+q (formula 2.)
By increasing q in formula 2, p will automatically decrease if 2n is fixed.
Author : chrisdecorte@yahoo.com
Page 1
2. We can now scan the range between 2 and 2n-2 for a suitable combination of q
and p to find couples of (q,p) where Goldbach is valid for 2n.
We can do this using the following new formula where we temporarily put q=x
and p=2n-x:
௫ିଵ
ሺଶି௫ሻିଵ
ୀଶ
ୀଶ
ߨݔ
ܩሺݔሻ = ෑ sin ቀ ቁ .
݅
ෑ
ߨሺ2݊ − ݔሻ
sin ൬
൰ <> 0 => ݍ + = ݊2 ݀݊ܽ ݍ = ݔ
݆
(formula 3.)
We tested the formula in PARI/GP using the following code (example for 2n=22):
for(two_n=22,22,for(x=2,two_n,print(x,"
", prod(i=2,x1,sin(Pi()*x/i),{i=1})*prod(j=2,two_n-x-1,sin(Pi()*(two_n-x)/j),{j=1}))))
We found the following correct result:
We now have to prove that there is always a valid q in formula 3 to prove Goldbach’s
conjecture.
