Focus, focusing all eyes in one place, and even the afterglow cannot scan other things; defocusing, on the contrary, the eyes are scattered everywhere, without a focus, but there is a focus everywhere.
The ancients also said that "the authorities are confused, and the bystanders are clear" -: The people in the authorities are trapped in the situation and their eyes are only on that point and they cannot find a crack; while the bystanders can scatter their eyes everywhere, and may inadvertently find a breakthrough.
For example, the musician in the orchestra must be familiar with his or her performance part, and pay attention to the instructions of the conductor and keep up with the rhythm of others, so that he can play harmonious and wonderful repertoire. This is a process of coexistence of defocus and focus.
Sometimes we find that if we find another way, we find the best solution. It is precisely because we cannot find the answer through focus, but instead find a way out of defocus.
There is a story on chemically, the discovery of the structure of benzene ring .
After accurate determination by chemist Rilar and others, it was found that the relative molecular mass of benzene is 78, and its molecular formula is established as C6H6.
But what form its structural formula is still difficult to explain.
German chemist Kekule is also constantly seeking this answer, but after doing various hypothetical experimental research, there is still no answer. But he was really tired and needed a rest, so he had to fall asleep with the problem in dishearteningly.
In his dream, he saw a snake, which bit his tail very strangely and turned into a circle. A strange ring? Why is it so strange?
Kekule was instantly inspired. Can be benzene be a ring structure? After Kekule woke up, he quickly conducted hypothetical research on this inspiration. He proposed that benzene is a cyclic structure connected by alternating single and double bonds between six carbon atoms.
1935, scientist Jans used X-ray diffraction to confirm this hypothesis: the benzene molecule is a flat hexagon, and the bonds between the six carbon atoms inside are exactly the same, which is a special bond between a single bond and a double bond.
Don't be so single-minded. If you change your perspective and be half-minded, you may be able to find the answer.
The above thoughts come from "How to create your optimal working rhythm".
