“
The beauty of a mathematical theorem depends a great deal on its seriousness, as even in poetry the beauty of a line may depend to some extent on the significance of the ideas which it contains.” ―
G.H. Hardy, a great mathematician (This quote is from Hardy's 'A Mathematician's Apology').
"
A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories. One can imagine that the ultimate mathematician is one who can see analogies between analogies." --
Stefan Banach, a great mathematician.
Hmm. 'Mathematical Proof' (
https://www.wikiwand.com/en/Mathematical_proof ) by Wikiwand is quite good! Enjoy!
