He IP number? 3.14, most people know how to answer. But what very few people know is how much hide this infinite sequence from which we draw each year more decimals which accompany the 3. They are already located, although the sources differ greatly, in more than 60 billion» declares mathematician David Ríos in statements to Efe. But this figure goes beyond mathematics. The “3.141592….” (the sequence is infinite) was for centuries the more fascinating and studied numbers (also in schools). For many reasons.

First for reveal the relationship between perimeter and diameter of a circumference – crucial in calculation – but then in all areas of knowledge: in physics, in engineering, in numerous medical advances, in quantum computing or to understand the rules which govern the Universe. This irrational number which hides the keys to navigation, algorithms or artificial intelligence.

## What is the number Pi

The professor of risk analysis and data science at the Institute of Mathematical Sciences (ICMAT) of the High Council for Scientific Research explained that the number Pi is a number “transcendent”, “irrational” and “infinite” and it will always be like this, even if each year progress is made in the knowledge of the number of decimal places which accompany 3 and which are already, although the sources differ greatly, at more than 60 billion.

The importance of this number is such that it is also behind the algorithm that advises the next purchase, which suggests a song or a book, economic forecasts and automatic machine learning, as observed by l ‘expert. However, he recognizes that although this mathematical constant appears in virtually all scientific disciplines due to the properties and solutions it brings to each of them, many of them properties are still unknown. In other words, many of the solutions to certain challenges facing humanity (economic, medical or security) lie behind mathematics.

## From number to day

This transcendent, irrational and infinite number is so important that it has its own day. But not for long. The idea came from physicist Larry Shaw in 1988 in San Francisco. But officially celebrated since 2009 Following a resolution by the United States House of Representatives, the date was approved to mark the existence of the famous mathematical constant and, by extension, the role of science and mathematics in solving problems in physics, engineering or medicine, among others.

In this sense, UNESCO seeks to ensure that the Internet search engine success These are mathematical algorithms, in which secure communications are based on number theory, or in which certain medical devices (resonance or scanner) start from the collection of digital data that an algorithm transforms into images.

The decoding of the human genome constituted a scientific milestone supported by the statistics, computer science and mathematicsthat transform computer vision, machine translation or autonomous vehicles and serve to understand how epidemics spread, to design electoral systems and legislation or to better understand natural risks and prevent disasters. Now, in addition to knowing which figure Pi is hiding, you also know its current implications.
