Quiet

A father and son went hunting together for the first time. The father said "Stay here and be very quiet. I'll be across the field." A little while later the father heard a blood curdling scream and ran back to his son asking, "What's wrong? I told you to be quiet."

The son answered, "Look, I was quiet when the snake slithered across my feet. I was quiet when the bear breathed down my neck. But when the two chipmunks crawled up my pant legs and said 'Should we eat them here or take them with us?' I panicked..."

Farkas Bolyai

Died 20 Nov 1856 at age 81 (born 9 Feb 1775). Farkas (Wolfgang) Bolyai was a Hungarian mathematician, poet and dramatist who spent a lifetime trying to prove Euclid's (fifth) postulate that parallel lines do not meet. While studying at the University of Göttingen, he met as a fellow student, the noted German mathematician Carl F. Gauss, with whom he corresponded as a life-long friend. Bolyai taught mathematics, physics and chemistry at Marosvásárhely all his life. He discouraged his son, János Bolyai, from studying the parallel axiom as he had, writing in a letter to him: “For God's sake, please give it up. Fear it no less than the sensual passion, because it, too, may take up all your time and deprive you of your health, peace of mind and happiness in life.”Wolfgang is the German form for the Hungarian name Farkas.
