San Marino is not only the longest uninterrupted sovereign state and has the world’s longest-running constitution which dates back to the year 8th in 1600.

Nonlinear Sciences > Exactly Solvable and Integrable Systems. Ten of the oldest countries in the world (Updated 2021) Study on Darboux polynomials, and their role in finding other integrability quantifiers. Human life started to evolve many millions of years ago the first evidence of human civilizations emerged relatively recently in the timeline of the human race. A case study on third-order ordinary differential equations with nonlinearity.

A few of the first civilizations were established in the period of 6500 BCE after which people stopped living in nomadic communities and began to settle and build a community in one place. Abstract In this paper we describe a method of formulating extended Prelle-Singer method’s quantifiers by using Darboux Polynomials for nonlinear third-order normal differential equations. These first settlements quickly resulted in large cities and the idea of separate nations and countries were soon to follow. In order to understand the Darboux polynomials along with its cofactors, it is possible to extract the Prelle-Singer extended method’s variables without analyzing the PrelleSinger method’s determinative equations. Some of the first countries emerged shortly after civilization was born, and all these countries were founded many thousands of years ago. Three different scenarios are considered of well-known Darboux polynomials.

10. In the first one we show that the equation is integrable in the third-order nonlinear problem by using prelle-singer’s quantifiers of the two well-known Darboux polynomials. San Marino. If we have only one Darboux polynomial, then the integrability of the equation will be determined by the case of $2$. Year of founding Year of Founded: 301, CE Founder(s): San Marinus Capital City The the City of San Marino Current Population: 33,344 (2018 estimate) In the same way, cases $3$ analyzes the integrability particular system, where there are two Darboux polynomials, and a number of Prelle-Singer method quantities.

The established interconnection not just aids in the derivation of the quantifiers that can be integrable without having to solve the fundamental determining equations.

Although many countries have more lengthy histories, San Marino is often described as the oldest city on earth because it has been an unbroken sovereign state since the year 301 CE. It also offers a method to establish that the integrability is complete and assists us to determine the general solution to the given equation. It was founded on the 3rd September 301 CE, when Saint Marinus constructed the Church at Monte Titano. The utility of this technique using three different scenarios. This small church later grew into the capital city San Marino, the capital of the country’s small size.

Ancient Iran The ancient Iranian state, also named Persia throughout the Western world up until 1935, was established in the year 555 BCE in the Achaemenid Empire. Starting from The Ming Dynasty to the Valley of the Kings, read interesting books that take your imagination on a voyage across time. Before the advent of the Persian Empire, various groups of people resided in the region that later became Iran which included the Elamites who were an ancient civilization of the pre-Iranian period which settled in the Western along with the Southwest region of present-day Iran along with the Medes who were in control over the majority areas of Iran before the Persians moved into. Rating: 3.1 /5 (591 votes cast) Cyrus II (commonly known as Cyrus the Great) established the Persian Empire around 550 BCE after he defeated his Median, Lydian, and Babylonian empires and took control over Iran. Current 3.07/5. The Achaemenid Empire controlled Iran from the time Alexander the Great conquered the Persian Empire in 330 BCE.

This is the largely untold story about Nikola Tesla, the discoverer of alternating currents, the pioneer of robotics, radars, and transmission wireless. Today, Iran was established in 1979, following the Iranian Revolution ended the monarchy and an Islamic Republic was established. He revolutionized the course of history around the world however he wasn’t acknowledged with the respect he deserved. Did You Not Know? Written by Frank Leanza.

Japan often refers to the year 660 BCE as the year of its establishment since this was the time the time that the first Emperor of Japan was Emperor Jimmu took the throne, and inaugurated Japan’s imperial lineage. Hull.

Emperor Jimmu’s name is believed to be an emperor mythic and legendary to Japan which is thought to have been the descendant of the goddess sun Amaterasu. Rating: 2.8 /5 (287 votes cast) He’s mentioned as the nation’s first Emperor in two of the earliest chronicles, Kojiki , and Nihon Shoki . Current 2.78/5. The earliest emperors in Japan after the emperor Jimmu is believed to be also legendary since there isn’t enough evidence to show that they really existed. If you’re a lover of books about historical romance, then you’ll love this fictional story of the final days of Jane Austen’s life.

Although historians don’t know that these early emperors actually existed, they are aware that the first people arrived in Japan from the Asian mainland at around 13000 BCE and the earliest documented history of Japan was recorded in the Kofun period (c.250 AD – 538 AD).
