Pythagoras and Hippasus

Pythagoras is mathematician and philosopher from Greece ( 582 – 496 B.C ).
Pythagoras explain that a right agled triangle, quadrat of hipotenusa is equals of the total length of salient angle adges quadrat. This theorem called Pythagoras Theorem because Pythagoras has been considered this theorem discoverer. Althought in fact this theorem has been known before, such as mathematician India ( in Sulbasutra Baudhayana and Katyayana ), Old Greece, and Babylon at before Pythagoras born, but Pythagoras is the first person who proof theorem with mathematical. So, he has been considered Pythagoras Theorem discoverer.

Then Hippasus ( mathematician and philosopher from Old Greece ca.500 B.C ), he is Pythagoras’s follower. Previosly, Pythagoras and his followers deem that all number is rational number, or can explained in comparison round number. Then Hippasus explain that √2 is irrational number. He prov with reductio ad absurdum and he succes prov that √2 is irrational number. Hippasus is irrational number discoverer. But, because this discovery, he killed by Pythagoras. Pythagoras does not admitted his philosophy mistake, and he does not opposed Hippasus, althought that is contradicted with his philosophy. And then, Pythagoras kill Hippasus.

Development Of Mathematics

Mathematics History is knowledge which learned mathematics from numbers of time. with mathematics discoveries. Then Pythagoras is mathematician from Greece ( 624 - 550 B.C ). He has been considered Pythagoras Theorm discoverer, althought in fact this theorm has been known bofore. He is tMathematics have been exist since Before Christ ( B.C ) period. It has been beginning from the philosophers ideas.
Mesopotamia, Babylon, old Egypt, and Old Greece are the influential countries in mathematics. Thales is the first person who has been conneted he first person who proved this theorm in mathematical. Therefore, mathematics is the knowledge which have to have proof.
Philosophers, such as Socrates, Plato, Aristoteles, etc also have a role in mathematics development. Their philosophies have been used in many science, such as mathematics. Furthermore spring up many mathematicians with their own teories. Such as in 1900 apperars the modern mathematicians, like Sir Michael Francis Atiyah and Isadore Singer proof Atiyah-Singer Index theorm in 1968. In 21th century also give development in mathematics. They are the people who give contribution for mathematics.
We also have to learn mathematics and try to make discovery in mathematics. So that, we will become the part of mathematics history in the future. No time for laziness.
