model okay and the idea is that each circuit here it's going to be small relative to its input but you get a separate circuit for each input length that's sort of the extra thing you get you get this infinite description okay so this circuit family right here alright that's a notion of P poly so you anything programs have infinite link descriptions huh excuse me why study this model okay Theory dork that's all fine and good but why don't you go play off in theory land well all the rest of us go change the world okay okay well I have
