Was it just a dream?

– The other day I had a wonderful dream!

– It is called day dreaming. Yes, it can be rather pleasant.

– I was dreaming about a parabola and a straight line.

– I sometimes dream of me and Paula Bola!

– Do you know what a parabola is?

– I have one in my garden.

– Its equation is ax^2 + bx + c.

– I don’t know. A friend gave it to me.

– And a straight line is dx + e.

– I love the alphabet!

– In my dream, see the image above, I saw a straight line that intersected a parabola only once!

– I don’t see anything.

– I followed the line upwards, but never did it cross the parabola again.

– Amazing!

– When I woke up I could not find a, b, c, d, and e.

– Did you look under your pillow.

– That’s the problem. I sleep without one.

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?

Public

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
