Problem 2.

Author: Murashkowsky N. Y.
Topic: Methods.
Content of the problem: An Amazonian fish lives near the surface of the water and gets its food both under the water and over the water. The one who sees clearly under the water doesn’t see as well in the air, and vice versa. That is why sea-animals and land animals have eyes differently designed. What eyes should an Amazonian fish have to see well both in the air and under the water?
Solution: - ?

Problem 3.

Author: Klyastutis Usyavichus.
Topic: Methods.
Content of the problem: In order to catch insects in the spider’s web, the web’s threads should be sticky and invisible, transparent. But the problem is: some kinds of the day spiders, because their webs are invisible, suffer from the birds flying by. It is possible, of course, to make a web visible, but in this case, insects won’t get there. What should be done?
Solution: - ?

     Try to single out a method to solve these contradictions.

     Nif-Nif, Naf-Naf and Nuf-Nuf started construction.
     "The house should be big in order to have space for games and entertainment", said Nif-Nif.
     "No, no", argued Naf-Naf, "the house should be small to hide us and to give us privacy."
     What did Nuf-Nuf suggest?

     Draw your solution.

     "We have to paint the walls white and we will be able to see our house from far away", said Nif-Nif.
     "Let’s paint the walls black and in winter against the snow background we’ll see our house clearly", argued Naf-Naf.
     "Don’t hurry", said Nuf-Nuf, "let’s do the following…"
     What did Nuf-Nuf suggest?

     Draw your solution.

     Draw your solution.

     "The house should be light, to be easily built".
     "The house should be heavy, to be solid against the wind"
     In this situation Nuf-Nuf found the way out.
     What did he suggest?

     Draw your solution.

     "The house should be high to give a good view from the roof", said Nif-Nif.
     "The house should be low, to be easy to climb the roof", argued Naf-Naf.
     "We’ll make all that", answered Nuf-Nuf.
What will you suggest?

    "I like everything round. I want our house to be round",said Nif-Nif.
     "I like everything square, I want our house to be square", argued Naf-Naf.
     "Nothing can be easier", answered Nuf-Nuf.
     How to do it?

     Draw your solution.

Each of these contradictions is a basis for a problem. Try to articulate problems, devising a small plot to each contradiction.

Lesson 2

Problem 4.

Author:
Topic. Methods.
Content of the problem: It is the Zoo. It is necessary to measure all the snakes to within 1 centimeter. The person responsible for the snakes is sick. What to do?
Solution: - ?

Problem 5.

Author: Altshuller, G. S.
Topic: Methods.
Content of the problem: In the open railway platforms the pine logs were being loaded. The controllers were measuring the diameter of each log in order to calculate the volume of all logs. The work proceeded slowly, the controllers were going to delay the train to finish the process of measuring... And suddenly the inventor arrived. "I have got an idea!" he said. "The train will leave in 5 minutes. Take…" What did he suggest?
Solution: - ?
Source of information: “And Suddenly the Inventor Appeared…”
