Ennio De Giorgi

Ennio de Giorgi was a really smart man who made big discoveries in math. He found out some really important things about shapes called geometric shapes, which are like the things you make out of playdough or see in your coloring books.

Ennio de Giorgi was really interested in curved shapes that are called surfaces. He figured out that there are some surfaces that are "smooth" and others that are not smooth. A smooth surface is like a table that has no bumps or scratches, while one that is not smooth might feel rough like sandpaper.

Ennio de Giorgi figured out that there are only three types of smooth surfaces that can exist. He used a lot of really hard math to explain why this is true. This was a really big deal, because he was able to describe something about the world around us that nobody else knew before him.

His discoveries helped people to understand the shapes and patterns that make up our world, and they are still used by mathematicians and scientists today.
