method [Theme]

Around misunderstood beat around the Bush, and the unknown can be selected from any known.

Three mathematicians and three physicists are going to go by train to another city for a conference. They meet in front of the cashier at the station. The first is the turn of the physicists, and they, like all normal people buy the ticket on the person. Mathematics buy one ticket for all. "How so?" - wonder of physics "Because the train controller, you without a ticket kicked out!". "Don't worry" - math the answer - "we Have a METHOD".
Before sending the train physics are getting in their cars, but I try to follow the use of the mysterious "method". Mathematics all stuffed in a toilet. When the controller fits to the toilet and knocks the door pritvoryaetsya, leans out the hand with the ticket. The controller takes the ticket and then all of them go to the destination.
After the conference the same again, meet at the station. Physics, inspired by the example of the mathematicians bought one ticket. Mathematics do not take any. - What you show the controller? - We have a METHOD.
In the train of physics stuffed in a toilet, mathematics in the other. Shortly before departure, one of the mathematicians coming to the toilet, where they hide physics. Knocks. Put out the hand with the ticket. A mathematician takes a ticket and returns to the colleagues.
The moral: you Cannot use mathematical methods without understanding them!
