History has been filled with remarkable figures who have changed the course of the world through their brilliance and dedication. One such figure is the ancient Greek mathematician, Pythagoras. He lived around 500 BCE and was one of the earliest mathematicians and philosophers to make significant contributions to mathematics and science. He is remembered today as the founder of the Pythagorean school of thought, and his influence on modern mathematics is still felt today. In this article, we will explore the life and times of Pythagoras and his lasting legacy on mathematics and science.

**Who was Pythagoras?**
Pythagoras was born around 570 BCE in the Greek city of Samos. He was an accomplished philosopher, mathematician, and scientist. He is best remembered for developing the Pythagorean Theorem, which is still used today in mathematics and engineering. Beyond this, he also made numerous other contributions to mathematics, including the study of irrational numbers and geometry.
Pythagoras is also credited with founding the philosophical and religious school of thought known as Pythagoreanism. This school of thought focused on the concept of harmony between all things, as well as the importance of numbers and mathematics in understanding the universe.

**Pythagoras’s Life and Times**
Pythagoras is believed to have studied mathematics and philosophy in the city of Miletus before traveling to Egypt and Babylon. He was a great admirer of the ancient Greek philosopher, Thales, and was greatly influenced by his teachings. After his travels, Pythagoras settled in the Greek city of Croton, where he established his own school, the Pythagorean School.
At the school, Pythagoras and his followers studied mathematics, philosophy, and religion. They also developed a way of life based on the principles of harmony and order, which was known as the Pythagorean way. This way of life was based on the belief that numbers and mathematics were the basis of all things in the universe.
Pythagoras’s teachings were controversial, and he and his followers were eventually expelled from Croton by the local authorities. He then moved to Metapontum, where he is believed to have died around 500 BCE.
**Pythagoras’s Contributions to Mathematics**
Pythagoras is best remembered for his contributions to mathematics, and he is credited with making many significant advances in the field. He is credited with being one of the first to use geometry to solve problems, and he is often referred to as the “Father of Geometry”. He is also credited with developing the system of irrational numbers, which was an important advancement in mathematics at the time.
In addition to his contributions to geometry and irrational numbers, Pythagoras is also credited with developing the Pythagorean Theorem. This theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. This theorem is still used today in many fields, such as engineering and architecture.
**Pythagoras’s Religious Beliefs**
Pythagoras was a deeply religious man, and his beliefs had a great influence on his teachings and writings. He believed that the universe was made up of mathematical and numerical principles and that numbers had a special power and meaning. He also believed that the soul was immortal and that the universe was composed of cosmic harmony.
These beliefs were closely linked to his teachings on mathematics, and he believed that mathematics was the tool that could be used to understand the universe and its underlying principles. This idea of cosmic harmony is still seen in some modern religious beliefs today, such as in the concept of karma.
**Pythagoras’s Impact on Ancient and Modern Mathematics**
Pythagoras’s contributions to mathematics had a profound impact on ancient and modern mathematics. His ideas on geometry, irrational numbers, and the Pythagorean Theorem shaped the development of mathematics for centuries to come. His ideas are still used in modern mathematics and engineering, and his influence is still felt today.
Pythagoras’s philosophy was also influential in the development of modern philosophy and religion. His ideas of cosmic harmony and the power of numbers still resonate in modern religious beliefs and philosophies. His idea of the soul is immortal and the concept of karma is still seen in some modern beliefs today.
**The Pythagorean Theorem**
The Pythagorean Theorem is perhaps Pythagoras’s most famous contribution to mathematics. This theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. This theorem has been used in mathematics, engineering, and architecture for centuries, and it is still used today.
The theorem is also used in many practical applications, such as calculating the length of a side of a triangle, determining the area of a triangle, and calculating the distance between two points. It is also used in computer programming and engineering for tasks such as calculating the distance between two points in a coordinate system.
**Other Contributions by Pythagoras**
In addition to the Pythagorean Theorem, Pythagoras also made numerous other contributions to mathematics and philosophy. He is credited with developing the concept of irrational numbers, which is still used today in mathematics and engineering. He is also credited with developing the system of musical harmony, which is still used today in music theory.
He is also credited with developing a system of logic and philosophy, which was based on the concept of harmony and the power of numbers. This system of philosophy is still influential today, and it is still seen in some modern religious beliefs.
**Pythagoras's Legacy**
Pythagoras’s legacy is still felt today in mathematics, science, and philosophy. His contributions to geometry, irrational numbers, and the Pythagorean Theorem are still used in modern mathematics and engineering. His ideas on the power of numbers and the concept of cosmic harmony still resonate in modern religious beliefs and philosophies.
Pythagoras’s legacy is also seen in the many schools and organizations that have been established in his name. The Pythagorean Society is a worldwide organization dedicated to the study and appreciation of the works of Pythagoras. There are also many schools and universities named after him, and his influence and ideas are still taught in many modern classrooms.
