The Fact Is There Are Few More

They [formulae 1.10 - 1.12 Of Ramanujan] Must Be True Because, If They Were Not True, No One Would Have Had The Imagination To Invent Them.

As History Proves Abundantly, Mathematical Achievement, Whatever Its Intrinsic Worth, Is The Most Enduring Of All.

The Primes Are The Raw Material Out Of Which We Have To Build Arithmetic, And Euclid's Theorem Assures Us That We Have Plenty Of Material For The Task.

Reductio Ad Absurdum, Which Euclid Loved So Much, Is One Of A Mathematician's Finest Weapons. It Is A Far Finer Gambit Than Any Chess Play: A Chess Player May Offer The Sacrifice Of A Pawn Or Even A Piece, But A Mathematician Offers The Game.

I Do Not Know An Instance Of A Major Mathematical Advance Initiated By A Man Past Fifty
