A very complex question, for every complex question, there is a simple wrong answer

What you say, and what you do, is stupid and childish ...

Early death and early reincarnation OK?

One is a brother, the other is a girl I like, of course, I choose to quit.

Giving or not giving a gift doesn't say anything.

Tell that girl, you're in a hurry, and if you don't tell her, you'll never have that chance, while she's not your brother's girlfriend yet.

I would like to ask a question.

Even if you are together, will there be any results? Where will you be when you graduate? Where will she be? There is no banquet in the world, but love is not a banquet and not a child's play, think clearly about what your future will be?

Sorry, it's not one question anymore, it's several. In short, the current task is to study hard, as for women, it's not too late to talk about it later!

Good luck!

Children study hard and fall in love!

They are all students, and these questions are still as your brother said: go with the flow and be better friends.

If you put your energy into studying, there will still be many forks in the road in the future, and whether it is flat or rugged will require you to work hard to learn to deal with it.

The 2B pencils we used for exams when we were kids, I don't know if you have carefully observed them?

The cross-section can be seen as a regular hexagon, with a thin graphite in the middle and surrounded by wood, such a structure that we take for granted and use.

Have you ever thought about such a coherent phenomenon, what is the manufacturing process of pencils?

Maybe we take it for granted that this is not simple, it must be to make the shell first, and then put the core graphite into it!

But when you think about it, it seems that this kind of process is self-defeating. It can be seen that the ink core and the wooden shell are very tightly pasted, and there is almost no gap, which shows that the outer diameter of the wooden shell and the inner diameter of the ink core are extremely close. There is a lot of friction to overcome, and if you imagine it, it's too difficult!

So how exactly is a pencil made?

If you zoom in on one end of the pencil and look closer, you will see that there appears to be a central dividing line on the end of the pencil, and there are subtle differences in the color and grain of the wood on either side of the dividing line.

What does this mean? Could it be that there are two different pieces of wood that make up this shell?

Following this line of thought, further speculation, a more reasonable pencil manufacturing method has surfaced, perhaps simply the following three steps:

In the first step, take a wooden "half shell" and place it with the concave side facing up;

In the second step, place the cylindrical refill in the half shell;

In the third step, another wooden "half-shell" is placed on top of it, like a lid.

Misunderstandings about the pencil making process come from "taking things for granted" in the thinking process.

We take it for granted that since the pencil is divided into a refill and a case, the way to make a pencil is to insert the refill into the case. If the refill is represented by a and the shell is represented by a b, then we take it for granted that the making of a pencil is a simple a+b, and in fact, the process of making it should be: (a+, we are deceived by the obvious, and always take the easiest answer to think of as the only correct answer, as the writer George Bernard Shaw said

For every complex question, there is a simple wrong answer. ”

In any field, after studying to a deeper level, you will find that many of the original assumptions will be subverted. Those things that seem to be natural on the surface are actually wrong, just like the craftsmanship of making a thing, which may contain ingenuity and wisdom that most people can't imagine, they are likely to come from a few flashes of inspiration that have emerged from the long-term practice process, if you learn to look at things from such a perspective, then you must get more than others.

Hello! There are no simple solutions to complex problems: the world is rich and complex, and there are many ways to deal with problems, but they can be roughly summed up in two ways:

One is to "simplify" complex things; The other is to "complicate" simple things. There is such a slogan: "Complex things are done simply, simple things are done seriously."

When we are able to see complex problems clearly from a simple perspective, this actually reflects the depth and height of a kind of thinking. Simple problems are solved in simple ways, which is the level of ordinary people; Complex problems are solved in a simple way, at the level of the wise. Smart people understand that only by simplifying complex work, learning to cut work that has nothing to do with the essence, grasping the root of the problem, and expressing the problem in the most concise way, this is the basic skill that successful people should have.

The more complex the problem, the more you can't mess around, no matter what kind of problem there is, there will be a corresponding way to solve it. Generally, a problem must first be analyzed, and the complex problem should be broken down into small problems, so as to find corresponding solutions to solve them. Find a way to find the right person or thing to help solve the problem.

Problems are contradictions, and discovering problems is to discover the existence of contradictions, and to generate the need and motivation to solve contradictions, which is the process of transforming the needs of society into individual thinking activities. Finding a problem is the beginning of problem solving, and it is also the driving force for problem solving. Only by discovering problems can people be motivated and motivated to engage in problem-solving thinking activities.

Asking questions is the beginning of problem solving.
