How to always win at the game of matches

The rules of the game of matches are very simple: a certain number of matches are spread out in a row and each of the two players must take turns choosing between removing one, two or three. The player who removes the last match, loses. (Of course, the game can also be played with chopsticks … Read more

A 40-year-old geometric problem is finally solved

Discrete geometry studies the combinatorial properties of points, lines, circles, polygons and other geometric objects, and in this field where the resolution of this problem is important. We refer to the conjecture of the László Fejes Tóth area , which had been seeking its possible solution for 40 years. The zone conjecture Formulated in 1973 … Read more

How many binary numbers can you memorize in one minute?

The binary system , in computer science, is a numbering system in which numbers are represented using only two digits: zero and one (0 and 1). It is one of the systems that computers are used because they work internally with two voltage levels. Memorizing binary numbers is particularly difficult. Imagine something like this: 10101101011010010100000111101011001010101001010101 … Read more

The third Millennium Prize math problem could have been solved

The Millennium Prize problems were declared by the Clay Mathematics Institute on May 24, 2000. The problems are The P versus NP Problem, The Riemann Conjecture, The Yang-Mills Theory, The Navier-Stokes Equations, The Conjecture from Birch and Swinnerton-Dyer, The Hodge Conjecture and The Poincaré Conjecture. Now the third on the list could have been solved. … Read more

This is the largest Klein bottle there is

First described in 1882 by Felix Klein , the container that bears his name is closed, has no rim, and has only one "side" (that is, it does not have a clearly differentiated interior and exterior). The largest in the world is on display at the Kingbridge Center in Toronto, Canada, and is owned by … Read more

The world record for calculating decimals of the number Pi has been broken again: 62.8 trillion

The high-performance computer of the Center for Data Analysis, Visualization and Simulation (DAViS), of the University of Applied Sciences of Graubünden (FHGR), in Switzerland, has broken the world record for calculating decimals of the number Pi . It has thus surpassed the old world record of 50 trillion figures by 12.8 trillion new, previously unknown … Read more
