But the only answer that explains why it works 
|
|
|
|
|
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...

Your explanation doesn't account for why taking an amount of coins equal to the number of tails is necessary  But yes, the rest of the explanation could be simplified by math instead of words 
|
|
|
|
|
Gather 14 coins at a time. Feel them if found any tails keep them separate. Repeat until you find all 14 tails and then gather rest of them ( All heads ) and make two piles with same number of coins from head and tail pile. Best case you find all 14 in first go. Worst case you have to feel all 284 coins.

I can live with the best case, the worst case bothers me however... There is much simpler way to do it

I'm not sure there is a switch inside the room, but can 'feel' for it...

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

Well spotted.

Tell them where the couch is. They will all go and hide. No coins, no problems.

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...

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??)

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

God was once approached by a scientist who said, “Listen God, we’ve decided we don’t need you anymore. These days we can clone people, transplant organs and do all sorts of things that used to be considered miraculous.”
God replied, “Don’t need me huh? How about we put your theory to the test. Why don’t we have a competition to see who can make a human being, say, a male human being.”
The scientist agrees, so God declares they should do it like he did in the good old days when he created Adam.
“Fine” says the scientist as he bends down to scoop up a handful of dirt.”
“Whoa!” says God, shaking his head in disapproval. “Not so fast. You get your own dirt.”

I love that one, but I am a sort of believer in the oneness of matter and mind, and occasionally matter manifests out from mind, and the details of the matter are those of projection, so the closer you look, the more detail you see, i.e. in the beginning, there was only awareness, and after incredibly much division and projection from that first, unified awareness, we finally have details like minds, bodies, and dust.

You still need the mind to come from somewhere.
|
|
|
|
|
The mind arises spontaneously out of what the universe is made of, an indescribable quantum flux that has potential for both mind and matter.
If you ask who or what made that, I'll invoke Occam's Razor and say it just always was.

I agree and disagree with what you're saying. Gotta love paradoxes.
