Single Idea 9646

[filed under theme 6. Mathematics / B. Foundations for Mathematics / 2. Proof in Mathematics ]

Full Idea

I'm tempted to say that mathematics is so rich that there are indefinitely many ways to prove anything - verbal/symbolic derivations and pictures are just two.

Gist of Idea

There is no limit to how many ways something can be proved in mathematics

A Reaction

Brown has been defending pictures as a form of proof. I wonder how long his list would be, if we challenged him to give more details? Some people have very low standards of proof.


The 7 ideas with the same theme [establishing new certainties from a starting point]:

To decide some questions, we must study the essence of mathematical proof itself [Hilbert]
It seems absurd to prove 2+2=4, where the conclusion is more certain than premises [Russell]
For intuitionists, proof is inherently informal [Shapiro]
There is no limit to how many ways something can be proved in mathematics [Brown,JR]
Computers played an essential role in proving the four-colour theorem of maps [Brown,JR]
Hilbert proofs have simple rules and complex axioms, and natural deduction is the opposite [Beall/Restall]
Computer proofs don't provide explanations [Horsten]
