## A Quote by Karl Friedrich Gauss on effort, grace, and success

Finally, two days ago, I succeeded - not on account of my hard efforts, but by the grace of the Lord. Like a sudden flash of lightning, the riddle was solved. I am unable to say what was the conducting thread that connected what I previously knew with what made my success possible.

## A Quote by Karl Friedrich Gauss on satisfaction, time, words, and writing

## A Quote by Karl Friedrich Gauss on doubt, impossibility, lawyers, and proof

I mean the word proof not in the sense of the lawyers, who set two half proofs equal to a whole one, but in the sense of a mathematician, where half proof = 0, and it is demanded for proof that every doubt becomes impossible.
