I Know Numbers Are Beautiful.

God Has The Big Book, The Beautiful Proofs Of Mathematical Theorems Are Listed Here.

There Are Three Signs Of Senility. The First Sign Is That A Man Forgets His Theorems. The Second Sign Is That He Forgets To Zip Up. The Third Sign Is That He Forgets To Zip Down.

Suppose Aliens Invade The Earth And Threaten To Obliterate It In A Year's Time Unless Human Beings Can Find The Ramsey Number For Red Five And Blue Five. We Could Marshal The World's Best Minds And Fastest Computers, And Within A Year We Could Probably Calculate The Value. If The Aliens Demanded The Ramsey Number For Red Six And Blue Six, However, We Would Have No Choice But To Launch A Preemptive Attack.

A Mathematician Is A Device For Turning Coffee Into Theorems.

God May Not Play Dice With The Universe, But Something Strange Is Going On With The Prime Numbers.
