Triunghi ascutitunghic acoperit cu discuri

Post by Cezar Lupu »

Un numar finit de discuri acopera un triunghi ascutitunghic. Sa se demonstreze ca suma razelor este cel putin cat raza cercului circumscris triunghiului.

Mihai Baluna, "Scoala cu Ceas" 2007
An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says “You’re all idiots”, and pours two beers.
