Ancient Greek Mathematicians: Introducing Concept of Proof

Ancient Greek Mathematicians

• Around 2500 years ago, a group of revolutionary thinkers changed the way we think about mathematics by introducing the concept of proof.
• The ancient Greeks showed that mathematics is not just about calculations, but a way to understand and test the reality around us.

The Concept of Proof

• A proof is a convincing argument to prove the truth or falsehood of something.
• A simple example of a proof: if all dogs have four legs, then is this thing a dog? (Easy to prove it's not just because all dogs have four legs, not everything with four legs is a dog.)

Mathematical Proofs

• You may have heard of Pythagoras' theorem, a mathematical fact about the sides of a right-angled triangle.
• A valid proof is an undeniable fact, like Pythagoras' theorem.

Euclid's Contributions

• 200 years after Pythagoras, another Greek mathematician named Euclid perfected the method of writing proofs.
• Using some basic assumptions called "axioms", Euclid was able to prove many mathematical results.
• He collected these results in a great book called "The Elements", which formed the foundation of modern mathematics.

Impact of Proofs

• Proofs have been used in many areas, from cryptography to architectural designs.
• The ancient Greek mathematicians, scientists, economists, lawyers, architects, and almost everyone else have benefited from a new mathematical understanding of the world.

The Concept of Proof

• A proof is a convincing argument to prove the truth or falsehood of something.
• A proof involves making an argument to support a claim, using logical reasoning and evidence.

Mathematical Proofs

• Pythagoras' theorem is a famous mathematical fact about the sides of a right-angled triangle.
• A valid proof is an undeniable fact, like Pythagoras' theorem, that has been rigorously tested and verified.

Euclid's Contributions

• Euclid, a Greek mathematician, perfected the method of writing proofs 200 years after Pythagoras.
• He used basic assumptions called "axioms" to prove many mathematical results.

• Proofs have enabled people to make informed decisions, design innovative solutions, and understand complex phenomena.
