International Day of Mathematics

comes from their brilliant mathematical algorithms.

for secure communications relies on number theory.

like computed tomography scan (CT-scan) or magnetic resonance imaging (MRI) measure numerical data and a mathematical algorithm builds an image out of them.

are now transforming the world: for instance, computer vision, automatic translation, autonomous vehicles, etc.

is a triumph of mathematics, statistics, and computer science.

Mathematics were used to create the first photo of a black hole.

are optimized with mathematics.

can be better understood and controlled with the help of mathematics.

are accomplished with statistics and optimization.

that better represent the people's will are designed with the help of mathematics.

(floods, earthquakes, hurricanes) are better understood and hence prepared for in advance, with the help of mathematics, thus reducing disaster risk.

As Nelson Mandela said in June 1990, “Education is the most powerful weapon which you can use to change the world”. Mathematics are an essential part of education, which empowers people and opens new job opportunities.

and their consequences on biodiversity.

are needed in the move to a sustainable use of the world resources.

to extract data from satellite images and draw maps of urban, industrial, agricultural and forest areas, where traditional data are missing.

girls and women to a better future.

help every citizen to better understand the planetary challenges.

perspective symmetries, tilings, fractals, geometric curves, surfaces and shapes; patterns, scales and sounds in music.

from backgammon or chess to solving a Rubik's cube or playing Awale.

from navigations with the stars to GPS.

Without mathematics this would never be possible.
