Let us declare following first. The world is round, water runs downhill, iron is harder than paper, if you have doubts only a short slap to the back of your head with both materials should convice you immediately, the fastest way between two points is the straight line, a curve can never be a straight line, the sun is bigger than the moon, the altitude of the sun has nothing to do with the intelligence of blog-writing students. Everyone knows everything. No way, you say and you are right. What I mean is that we know some things, but not all. Have the answer and the problem is solved. Right, well, maybe. The first part of problem solving is to determine what the problem is. Sometimes we are too quick in presenting answers, we belief in knowing the solution without close analysis, without having recognized the problem in all details. To be engaged in the whole details of a problem brings you to a level where you can decide whether it is a big or a small problem, whether searching for answers is indispensable to life or is to be equated with the story about the toppled down bicycle in China.
By the way, there are even some people who give us answers or try to give us answers to questions nobody on earth would raise them. As a result of this awareness and due to the fact that a story should have an end I can record following: I am more the follower of the solely true elephant theory: “You can eat an elephant one bite at a time”.
