Pythagoras was a Greek philosopher and mathematician born in 570 BC who founded a school in Croton that made outstanding contributions to mathematics. He is known best for the Pythagorean theorem relating the lengths of the sides of a right triangle and believed that everything was related to mathematics. Leonhard Euler was a Swiss mathematician and physicist born in 1707 who made major contributions to subjects including geometry, calculus, trigonometry, and number theory. He standardized modern mathematics using Greek symbols still used today and contributed to fields like astronomy, mechanics, optics and acoustics. Euler discovered a new theorem in Euclidean geometry and wrote school books that helped define modern mathematical symbols.

Pythagoras
Pythagoras was born in 570 BC (Before the birth of Christ) on the island of Samos and he
died in 495 BC in the city of Metapontum. He was Greek philosopher and mathematician,
known best for the Pythagorean Theorem. He founded a school in Croton, which made
outstanding contributions to the field of mathematics. Pythagoras and his cult members
believed that everything was related to mathematics and agreed that, eventually, “all is
number”. Pythagoras is also famous for his study of sound and his theorem relating the
lengths of the side of a right triangle.

Leonhard Euler
Leonhard Euler was born Switzerland in 1707 and died in Russia in 1783. He was a
Mathematician and a physicist. Euler’s parents were very religious, his father being pastor
and his mother the daughter of a pastor. Euler himself, religion was very important too, but
even though he studied theology. He attended the University of Basel, where he studied
mathematics. At a very young age of 15 Euler received his Bachelor’s degree from the
University and one year later completed his Master degree. Euler contributed to the
subjects of geometry, calculus, trigonometry, and number theory. He standardised modern
maths using Greek symbols that continue to be used today. Euler contributed to the
subjects of geometry, calculus, trigonometry, and number theory. He standardised modern
maths using Greek symbols that continue to be used today. He also contributed to the fields
of astronomy, mechanic, optics and acoustics and made a major contribution to theoretical
aerodynamics.
Euler even found a new theorem in Euclidean geometry, a field which had been looked at as
completed. Here's a short explanation of this theorem:
The three heights of a triangle meet in point H, and the three
perpendicular bisectors in point M. Point E in the middle of the
line between H and M is the centre of a circle on which are all
the intersections of the heights and the perpendicular
bisectors with the triangle.
Euler didn't only make a lot of research, but also wrote a number of school books. Through
that he played an important part in defining the mathematical symbols we use today.
