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?

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
