For us, we know more and more cultural knowledge, but for us, we are still not satisfied with what we know now, but it is better to know more, which is one of the most basic reasons why everyone knows a lot of things now, and for us, the more we know, the better our life will be, even in the future.
Just like the experiment we are talking about now, throw a basketball at an altitude of 600 meters, and then we will see what happens when the basketball lands. This experiment was done by our foreign guys, and the result was unexpected. Because the ball didn't explode when it landed, it jumped up directly, so we would be shocked to see such an experiment.
How many experiments these people have done for us is a good explanation process when we encounter such a situation in our later life, and it is also a very happy thing for any of us. It is also the time when these people have so many experiments every day to tell us how these things are made and make great contributions to our scientific development.
