I am not afraid of chaos because chaos is the womb of light and life. What I don’t like is the mismanagement of chaos. – Frankétienne

At the captain’s table

-- Did I tell you about my last cruise?
– Just a finite number of times.
– We were eating at the captain’s table one night.
– How many in all?
– n, if I remember correctly.
– How many were liars?
– Less than half.
– Your task during the supper was to find one that told the truth?
– Exactly! How did you know?
– Let me guess that you could ask any guest about any other guest if they were liars or not.
– Yes, and the challenge was to find out using as few questions as possible.
– Couldn’t a liar give you wrong information?
– Yes, but he could also choose to tell the truth.
– How many questions did you need?
