I had this not only once. I walked into my room, and before I did that, I knew exactly what I wanted to do, but in the room I had no clue. I thought and thought and thought but couldn’t remember. Or I made a crossword puzzle and the correct answer was on the tip of my tongue but I couldn’t say it. Do you know what I mean? Or I tried to understand a simple equation like in maths. Or I wrote a word, the computer “said” it’s wrong and I looked and looked at it but couldn't find the mistake. And then someone came, and without thinking, solving the equation, writing the word correctly on which I was thinking about for such a long time. And he or she solved that in a blink of an eye and I thought: why haven't I figured it out?
I found this on the internet. When I read that kindergarten children can do this easily but a professor can’t, my first thought was that this is impossible. In fact, I have to say, I hadn’t figured it out when I first saw it. I thought about it, but couldn’t find the logic. Maybe we have learned too much, think too abstract, I don’t know. Here is it, maybe you find the right solution. Think about it and please write me your solution. I finally figured it out and so know its logic now ;)
