• Jacob Turner
• Mrs. Brady

2
Life

• Pythagoras born in 570 b.c.e on Samos (island
  in the eastern Aegean) died in 495 b.c.e in
  Metapontum, Italy
• Noted as a great Mathematician, Philosopher, and
  Scientist

3
Life

• During his early years he travelled widely,
  visiting Egypt and other places seeking
  information.
• He founded Pythagoreanism, a religion with roots
  in math.
• Called himself a philosopher and a lover of
  wisdom

Life

• Some of his discoveries are the Theory of
  Functional Significance of Numbers in the World
  and in Music, Pythagorean Theorem, Pythagorean
  Triples, and Pythagorean Identities.

Life

• Since no writings survived, it is hard to say if
  Pythagoras actually invented his works, if he
  stole them from someone else, or if his disciples
  created them hundreds of years later.

Mathematical Contributions

• These include the previous Pythagorean Triples,
  Pythagorean Identities, and most recognizably,
  the Pythagorean Theorem.

Mathematical Contributions

• In mathematics, the Pythagorean Theorem or
  Pythagoras' theorem is a relation among the three
  sides of a right triangle. It states in any
  right triangle, the square of the hypotenuse is
  the sum of the squares of the legs (the two sides
  that meet at the right angle)
• In equation form
• a2 b2 c2

Mathematical Contributions

• It is suspected that Pythagoras stole this theory
  from Babylonian Mathematicians who stole it from
  Egyptians. A theory of how he came up with this
  is that he went to Egypt, where he studied with
  the people known as the "rope-stretchers". They
  held a very special secret in the form of a rope
  tied in a circle with 12 evenly spaced knots.  It
  turns out that if the rope was pegged to the
  ground in the dimensions of 3-4-5, a right
  triangle would form.

Interesting Facts

• He formulated principles that influenced
  Aristotle and Plato.
• According to Pythagoras, 10 was the perfect
  number, so maybe he had a grasp of the metric
  system way before it was invented.

Interesting Facts

• He believed in the Transmigration of Souls (kind
  of like reincarnation).
• Because of this, he considered eating animals was
  cannibalism, for they might contain the souls of
  humans.
• He said that he had previous lives such as
  Euphorbus- son of Panthus, who fought in the
  Trojan War, a tradesman, and a courtesan
