In the university before a lecture on physics, which took place in a large classroom with levels, in which was located almost all our information faculty, several people came up with the entertainment of leaving paper aircraft.

Over the heads flew about a dozen aircraft, if one crashed into you, you raise, you send further.But someone and this seemed little.Suddenly several people resort with two huge sheets of paper (some special watmans for drawing, a diagonal probably a meter) and under the applause of the rest of the students, I begin to fold two fighter jets.

The launch was conducted from the highest levels of the audience under the headlines of photo and video cameras of many mobile phones.The larger aircraft planned to the board itself and, just hitting it, fell.The applause was spread.The second launch went with no less success.

But the change is over, with the call in the auditorium comes a physicist.The real professor with a beard and always in a suit and with a tie.He passes to the board and sees without exaggeration the mountain of aircraft...He raises one and launches in the direction of the students.
Surprising applause.
