For example, with the technology that everyone is using now, people in the communication industry and those in the Internet industry are studying in two completely different directions. How can people in the communication industry make it faster, more stable, and wider? People in the Internet industry are studying how to use 5G technology to provide technologies that cannot be provided now, that is, the 5G cloud driving that Li Yanhong mentioned in "Intelligent Transportation". This is the black box and the white box. The achievements of modern industrial civilization are to enjoy the work of predecessors in the form of black boxes. Our understanding of the black box is top-down, and the understanding of the white box is bottom-up, and this benchmarking in the field we are engaged in requires us to not only know but also know.
For example, in high school physics, there are many formulas. When you are learning these formulas, you are eager to use black-box thinking. You can indeed solve the example problems given in the book, but you don’t know how to special leads use them when you encounter complex problems. In which formulas, black box thinking can help solve the problem at hand, but white box thinking can determine how far you go. Although white-box thinking is relatively more long-term, white-box is very time-consuming, energy-consuming, and thinking, so you need to do more white-boxes in the fields you are engaged in or are interested in, clarify the principles, and find out ideas, but for It is not your own domain, it is more suitable to be a valuable black box.
Therefore, everyone should not look at dry goods with "filters", and blindly think that dry goods are good, but in reality, dry goods will also make us fall into the dilemma of "talking on paper". Even if we are facing dry goods that can be implemented, we must learn to use white boxes and black boxes. Think rationally and play its true value. 3. Dry goods or cognition which should you improve? Most of the dry goods in today's society are like the operation manual for the workers on the assembly line. This screw is turned 6 and a half turns, and the nut is turned 3 turns. If you think in a black box, you don't think about why this screw is screwed 6 and a half turns and the nut is screwed 3 turns. , once you encounter a new screw, you have no way of knowing how many turns the screw has been turned on.
