International holidays - International Pi Day

For more than two thousand years, the mystical, irrational and mysterious number Pi has raised a lot of questions among people The cryptic value (the Greek letter "π") is a symbol used in mathematics and represents a constant - the ratio of the circumference of a circle to its diameter Most people first learned about Pi in high school and know it as 314159, but modern mathematicians have calculated it to within a trillion digits The world record for memorizing the digits of Pi is 67,890 digits In everyday life we ​​cannot escape geometry For example, a cyclist uses a number to calculate the distance of a trip, and an engineer refers to it when designing car tires, water flows or buildings In rocket science, things like the Earth's trajectory are calculated using Pi Its unspoken presence can be felt in the circular ruins of Stonehenge, in the vaulted ceilings of domed Roman temples, and in the celestial realms of Plato and Ptolemy Pi has spawned numerous mathematical puzzles for centuries and inspired some of humanity's most iconic works of art All math lovers have a special event on their calendar - International Pi Day This holiday falls on March 14th and honors one of the most recognizable irrational symbols in mathematics - "pi" or "P", once again proving that mathematics can be an interesting science This crazy day was first celebrated in 1998, thanks to physicist Larry Shaw For fans of general relativity, this is also a reason to celebrate the birthday of Albert Einstein, who was born on March 14th The history of Pi Day is inextricably linked with the origin of the symbol itself The need to know it is as old as the origin of the wheel itself In many cultures and countries, mathematicians have repeatedly tried to unravel this mysterious meaning The ancient mathematicians were able to figure out the full coverage of the entire number up to the seventh decimal place, but the great Indian scientists deciphered it only to five characters Mathematical number enthusiasts take part in competitions and quizzes to learn the number of decimal places, or to write poems in which the number of letters in each word represents the subsequent digits of the number On this day, complex works of art are born, inspired by chaotic pi Many people, especially young people, wear T-shirts with the logo of the symbol On this holiday, it is customary to eat foods that begin with pi (pizza, cake) or foods that have a round shape, such as pancakes or cookies There are many other ways to celebrate the most amazing and transcendental day to understand this number and discover its amazing secrets
