Introduce three main issues in detail:
1, Goldbach conjecture
Goldbach was born in Konigsberg, Prussia, on March 1690. 1764 165438+ died in Moscow, Russia on1October 20th. Famous mathematician and religious musician. The most famous theory is Goldbach conjecture.
Brief description of the problem:1On June 7, 742, Goldbach proposed in his letter to Euler that every even number greater than 2 is the sum of two prime numbers. In his reply on June 30th of the same year, Euler said that he believed this conjecture, but he could not prove it. Mathematicians of all ages have tried, but until today, more than 250 years later, no one can completely prove this conjecture.
2. Fermat's last theorem
Pierre de Fermat was a French lawyer and an amateur mathematician in the17th century. Amateur is called amateur because Pierre de Fermat has a full-time job as a lawyer. But his achievements in the field of mathematics are not inferior to those of professional mathematicians. Mainly contributed to modern calculus.
Brief Description of the Problem: Fermat's Last Theorem, also known as Fermat's Last Theorem, was put forward by French mathematician Pierre de Fermat in17th century. After Fermat's last theorem was put forward, it experienced many people's conjectures and dialectics. After more than 300 years of history, finally in 1995, the British mathematician andrew wiles announced that he had proved Fermat's last theorem.
3. Four-color problem
Four-color problem, also known as four-color conjecture and four-color theorem, is one of the three major mathematical problems in the modern world. The four-color theorem of map was first put forward by Grice, a British college student who graduated from London University.
Brief description of the problem: Any plane map can make countries with the same border and different colors with only four colors. Expressed in mathematical language, the plane is arbitrarily subdivided into non-overlapping areas, and each area can always be marked with one of the four numbers 1, 2, 3, 4, without making two adjacent areas get the same number.
Nowadays, with the development of computer technology, although we have made tens of billions of judgments, we have only succeeded in quantity, which does not conform to the strict logic system of mathematics. Up to now, countless math lovers are still studying it.
