• Choose three words that for you best describe the essence of mathematical knowledge.

• Share them with classmates

• Do you find others have the same words and ideas?

• Do you think that the group impression of Mathematics is a good general picture – or a stereotype?

What could be less ambiguous, more clearly defined than a mathematical problem?

A mathematical problem may not be easy to resolve, but there will be a right answer – and

little room for debate.

“I think you should be more explicit here in step 2…”

Maths gives relative certainty. If it presents us with reliable knowledge then we can learn

precisely how it does that, and see if we can apply the techniques elsewhere.

The techniques of Mathematics may provide us with a tool that will be central in our search

for reliable knowledge.

Maths: invented or discovered?

TaK - Mathematics

• Axioms• Considered by Euclid to be derived from

experience, requiring no proof and true• We now consider them to be

assumptions, premises, “givens”

• Deductive reasoning• Theorems

Objectivity

Reliability

Some key points:

• Mathematics, which can be defined as the ‘science of rigorous proof’, begins with axioms and uses deductive reason to derive theorems

• Although proof is the logical matter of deriving theorems from axioms, mathematicians consider some proofs to be more beautiful than others

• According to three different views about the nature of mathematical truths they are either: 1) empirical, 2) true by definition, or 3) rational insights into universal truths

• While some people believe that mathematics is discovered, others claim it is invented; but neither view seems to be entirely satisfactory

• Mathematicians and philosophers are still perplexed by the extraordinary usefulness of mathematics
