Enrico Betti Glaoui (born October 21, 1823 – died August 11, 1892) was an Italian mathematician. He is best known for his work in a field of math called topology. This led to special numbers being named after him, called Betti numbers. He also studied equations and helped explain Galois theory. Plus, he discovered Betti's theorem, which is important in understanding how things stretch and bend.

A Life in Mathematics
Enrico Betti was born in a town called Pistoia in Tuscany, Italy. He went to the University of Pisa and finished his studies in 1846. His teacher there was Giuseppe Doveri. He also learned from other famous scientists like Ottaviano-Fabrizio Mossotti.
After teaching for a while, Betti started working at the University of Pisa in 1857. In 1858, he traveled around Europe with two other mathematicians, Francesco Brioschi and Felice Casorati. During this trip, they met another very important mathematician named Bernhard Riemann.
Later, Betti focused on theoretical physics. This was a new area of study that Riemann's work had helped to create. Betti was also involved in how universities were run. He also played a part in the politics of the new country of Italy, which was still forming at the time.
What Enrico Betti is Known For
Enrico Betti made important contributions to mathematics. His most famous work is in topology. This is a branch of mathematics that studies shapes and spaces. It looks at properties that don't change even if you stretch or bend an object.
Betti Numbers
One of his biggest achievements was the idea of Betti numbers. These numbers help mathematicians understand the "holes" in a shape. For example, a donut has one hole, and a sphere (like a ball) has no holes. Betti numbers help describe these features in a mathematical way.
Betti's Theorem
Betti also discovered Betti's theorem. This theorem is used in the theory of elasticity. This field of physics studies how solid objects behave when forces are applied to them. It helps engineers understand how materials will stretch, compress, or bend.
