Turn 14 coins over in one pile and all the others go into the second pile. Whichever 14 you turn over, there will be the same number of tails on both piles.

That works, but my answers were more entertaining ;P
Proud to have finally moved to the A-Ark. Which one are you in?

Damn, and I was only one step away from suggesting burning down the room so all the coins would be so scorched that none of them would be showing heads OR tails. And he had to go and post an actual answer... How's a guy supposed to troll in this kind of environment? :laugh:

Let see... After you separate 14 coins from the rest there is exactly n coins with tails in that pile... In the other pile there is 14 - n... Now flip the coins in the pile of 14, now it has 14 - n coins with tails, just as in the other pile...

ALL ABOUT COUNTING RIGHT In a dark room (so you can't actually recognize the coins, but feel and mover them only) there are 284 coins scattered on the floor. It is known that only 14 hast their tail upward. Create two piles of coins - using all the coins in the room - with the same number of coins with their tails up...

Make a pile of all the coins. Take 14 from there to make the second pile. Turn all the coins in the second pile upside down. the pile: H:270 T:14 two piles: H:270-t T:t; H:t T:14-t (t is whatever number of tails in the big pile) upside down the small pile: H:270-t T:t; H:14-t T:t (Done). Ooh, ooh. (Anyone notice the error in my answer to the ant on the rope? - should have been exp(100)-1 seconds. I had stopped the ant at the starting point of the other post rather than where it had moved to. - So I now agree with the other responder except I think he used 364 days in a year??)

Easy. Just say "Thank God we don't live in Medieaval times", and turn the light on.

If we do not live in medieval times, why should we thank God? And al-Khwārizmī - who lived even before - was able to solve it without electricity...

Yes, we all noticed. That's why we don't believe anything you say, any more.
