In old Greek we had many good mathematicians , that created many good theories , but it was many years ago.The most of you probably had forgotten this many times.Would you like to remember the Greeks?

So let's go!

The Greek's numbering system , was very alike the Roman's numbering system.It was like this:

I think we can start by the numbering system.

The Greeks had adopted and adapted many elements of mathematics from both the Babylonians and the Egyptians , but they create their own theories like the Xeno's Paradox Theory.

Pythagoras

Pythagoras was an Ionian Greek philosopher, mathematician, and founder of the religious movement called Pythagoreanism.He was born in the Island of Samos.He created many interesting and incredible theories, and one of them was the Theorem of Pythagoras, that basically say:"The sum of the square of the legs of a triangle equals the square of the hypotenuse."

Plato

**428-348 BC**

**384-322 BC**

Socrates was born in Athens and became one of the leading thinkers of ancient Greece. We can say that Socrates founded we know today as Western philosophy. He was influenced by the knowledge of another important Greek philosopher: Anaxagoras. His early studies and thoughts they discuss the essence of the nature of the human soul.

We had many examples of paradoxes, but the easiest understand is the paradox of Achilles and the Tortoise.

Now, that we talked about one theory, let's talk about philosophers.I will show you 4 famous philosophers.They are Pythagoras , Socrates , Plato and Aristotle.Let's go?

Socrates

Aristotle

His ideas about humanity have significant influences on education and contemporary Western thought. Aristotle is considered the creator of logic thought.He went to live in Athens at the age 17, where he met Plato, becoming his disciple. He found a school in Athens Lyceum focuses on the study of natural sciences. The philosopher valued human intelligence, the only way to reach the truth. His thoughts were followed and propagated by the disciples. Thought and written about various areas of knowledge: politics, logic, morals, ethics, theology, pedagogy, metaphysics, didactic poetry, rhetoric, physics, anthropology, psychology and biology.

The dark side of Pythagoras

There is also a VERY interesting story about Pythagoras. It is a legend, no one knows if it is true. Pythagoras believed that every number could be expressed as a fraction, that is, the Greek thought that all numbers were rational.One day, his student Hippasos, discovered a irrational number: The square root of 2. Pythagoras was very obsessed with perfection, so he didn't believe in irrational numbers.Then, one day, they were sailing in a boat, and Pythagoras threw his student overboard (to the sea) and swore that he would do the same if any other student said anything about the irrational number.

Curiosity

One day Socrates was taken with his mother to a complicated delivery, he began to think of her work, she should not raise the baby, just help at his birth and try to lessen the pain of childbirth, while if it did not cause a baby, then he would end up dying, and also the mother die. Socrates then began to think that he also, in a way, was a midwife, was within the knowledge of the person, because he was able to learn by itself, but it could help this knowledge be born and try to lessen the pain that so even today the teachings of Socrates are known maieutics.

Plato's school

“Let no-one ignorant of geometry enter here”

Curiosity

In front of Plato's school was wrote in big letters:

Curiosity

Aristotle, like Socrates was accused of impiety, but knowing that there was conspiracy against him does not wait for the court decision, closes the Lyceum and flees to his final exile. At the age of 61 Aristotle escapes to the island of Euboea, in the former home of his mother and dies at the age of 62. As for his death is not known for certain whether he was stricken by a stomach ailment, if drinking aconite or if he drowned at sea.

Of course that we have many much others good philosophers, but this is what I have today.

I hope you enjoyed.

See you next time.

By Rafael

Although remembered today as a philosopher, Plato was also a mathematician.Inspired by Pythagoras he founded his academy in 378 BC.His academy though mathematics as a branch of philosophy, as Pythagoras had done, and the first 10 years of the 15 years course a the academy involved the study of science and mathematics.
