【Story】
The width of the rails in the United States is uniformly 4 feet 8.5 inches, about 1.45 meters, because the American railway was first built by the British, so the British standard of 1.45 meters was adopted. The earliest railways in Britain were designed by people who built trams, and 1.45 meters is the standard used for tram tracks, while the first people who built trams used to build horse-drawn carriages, and the wheel width standard of horse-drawn carriages was 1.45 meters.
The wheelbase standard of the racecourse is determined by the width of the old road in the United Kingdom, because the width of the ruts on the old road is 1.45 meters. The width of these roads depends on the width of the Roman chariot, which is 1.45 meters wide, and the reason why the Roman chariot is 1.45 meters wide is because the butt width of the two horses is about 1.45 meters.
【Effect Understanding】
Correlation law: Everything in this world has a certain connection, and no one thing is completely independent. It's best to solve a problem somewhere else, rather than just focusing on one difficult point.
The law of correlation refers to the way that when people think creatively and look for the best thinking conclusion, because the thinking is inspired by the known characteristics of other things, they associate themselves with similar and related things to the thinking conclusion they are seeking, so as to combine the two to achieve the purpose of "interpreting the other in this way".
【Life example】
After reading this law, I think of a kind of problem type that I will encounter when reading a book, looking for a law. This experience is to find a way to connect with each other in a series of confusions, thus proving that this relationship is valid and reasonable for several options.
Related laws can be seen everywhere in life, such as going out to dinner because of salary, because of dinner, drinking some wine, resulting in a little dizziness, the next day at work, still no spirit, to slow down for several days. See, isn't this just an interconnected event? In fact, it is a common reason in life.
For life learning, the relevant laws also play a role, like memorizing the commonly used joint ideas of words, the branches that diverge when doing mind maps, life is not isolated, is not one thing accompanied by one thing?
