The 2020 International Day of Mathematics

On November 26, 2019, UNESCO proclaimed March 14 as the International Day of Mathematics , and in March 14, 2020, we celebrated it for the first time.

Mathematics is Everywhere

The theme chosen for the first IDM was Mathematics is Everywhere. We invited people worldwide to explore how mathematics can be found in science and technology, nature, and human activities of all kinds, even art and games.

  • Mathematics help plan and manage economic and social systems enabling the move towards a sustainable use of resources.
  • We travel the world guided by precise mathematical calculations based on the position of the sun, stars and GPS satellites.
  • We explore the inside of the human body through CT scans and MRI by building images out of numerical data through mathematical algorithms.
  • We discover how human thought works by building AI software that can learn and make decisions through mathematic models.
  • We photographed a black hole and continue exploring the edges of the universe with mathematics.

The Worldwide Video Challenge

As part of the celebrations we put together a video with clips submitted by math lovers all over the world who wanted to show that Mathematics is Everywhere

Visit our Worldwide Video page to learn more about the project and watch some other great submissions.

Many Celebrations

In 2020, people and organizations all over the world announced events in their cities:

Please note that many planned IDM events were cancelled due to COVID-19

The Live Global Launch

Due to the COVID-19 pandemic the official launch event of the International Day of Mathematics took place online. From the start of March 14, 2020, in New Zeland to the end in the west coast of the United States, we live-blogged photos of events and celebrations, videos, and special announcements through this website.
