Two logicians are on holiday in the Alps when a mad scientist captures them. The mad scientist knocks them unconscious and then tattoos their forheads. When they awake, the mad scientist says with a sneer:

" At least one of your has a tattoo on your forehead. Maybe both of you do...I'm not telling. I will allow you to go free if you have a tattoo on your forehead. All you have to do is walk out that door.

However, if your walk out that door and you do not have a tattoo on your forehead, I will put you to to death. I will leave you in this room, and if you communicate with one another in any way, you will be put to death.

Every day at noon, I will have the door unlocked briefly. You can choose to leave then and only then if you think you have a tattoo on your forehead."


1. Does any one escape? and

2. How long does it take?

3. What is a Logician?

A leader's credentials do not hang on his wall. They are written by the lives of those he has led.

I think they both would leave the first day (assuming they both have tattoos) because one thing I know about tattoos is that they hurt for at least a week, and might even scab over if they don't take care of it. Therefore, they would feel pain on their foreheads, and/or feel a scab :D

especially on a place like the forehead,
because it's just skin, then bone, without much in between
so it's much more painful to get a tatoo on places like the forehead, knee, ribs, stuff like that
