S. Issue πOne of the most well -known fixed mathematics, is celebrated all over the world in this Friday 14 March. History, chosen to represent the approach 3,14It is characterized by educational and recreational activities that highlight their importance.
Definition of representation A percentage between the circumference of the circle and its diameterThe number Bay It is an example of an irrational number, that is, his decimal series does not end or never repeat. It is widely used in mathematics and science, as it is necessary for accounts in areas such as engineering, physics and computing.
How is the day to celebrate me?
The Pi Mathematics Day celebrates and includes activities that mix learning and fun, according to the site PIDay.org. Some of the most popular celebration forms include:
- Objective food: Many people celebrate pies and pizza, taking advantage of the pun between “PI” and “Pie”. Some schools encourage students to measure the diameter of food and its surroundings before consuming them.
- Conservation competitions: There are competitions to know who can read most of the numbers Bay. The world record exceeds 70 thousand twelve places.
- Emmatic races: Some institutions organize a 3.14 mile (about 5 km) race, with prizes as rules for the winners.
- Sports Challenges: Many students participate in hunting treasure or Knowledge challenges On the number Bay.
- Technical activities: Some schools encourage the creation of inspired business BayAs a colorful graphic represents fixed numbers.
PI date
story Bay Returning to more than 4000 years. Civilizations, such as the Babylonians and the Egyptians, provided estimates of their value. Babylon π 3,125, while the Egyptians used a 3.16 approach.
The Greek mathematician Archimedes was around 250 BC, which developed a more accurate method of account BayUsing the registered and restricted polygons to a circle. Your approach showed that value Bay It was between 3,1408 and 3,1429.
The name “PI” began to be used in the seventeenth century, but Leonard Awar was popular in the eighteenth century. English mathematician William Ostrared began its use in 1647, but Leonard Ursle in 1737, which was popular Code π. The choice of the Greek message is due to the word “ocean”, which is written in the Greek language in the name of Perimetros.
Decisive mathematical discoveries
Issue study Bay It led to important athletic progress. In 1767, Swiss Johann Heinrich Lambert proved that π is irrational, that is, it cannot be expressed as an accurate breakage. In 1882, Ferdinand von Lindmann showed that π is also a transcendent as well, which means that it could not be a multi -border equation solution with rational transactions.
With technology progress, account Bay It has evolved greatly. Today, it was calculated to more than 31 trillion number, although in practice only 39 is necessary for most scientific and engineering applications.
