Re: coins problem

I also have the same puzzle, why cannot find one odd coin in (3^n1)/2 coins with n weighings?
Here I have another problem, saying "we have two same appearance coins, knowing one is standard, one is odd but don't know it is weight or light. weigh them with twopans, seems we can not find the odd coin forever?"
