Chapter 72 stone and bird

A stone thrown from a man's hand always falls back to the ground.The trajectory of a stone thrown is called a "parabola" by physicists.If you use more force, the stone will be thrown farther, and if you use less force, the stone will be thrown closer.Although the shapes of these parabolas are different, this trajectory must conform to the law of the parabola formula, and it cannot run out of this circle.Unless you throw the stone at a very fast speed, exceeding the speed of the first universe, and getting rid of the attraction of the earth, this curve will change in essence. In that case, the stone in your hand will become an artificial earth satellite.Of course, these are all questions that physicists discuss and care about. We only consider the problems in the first universe—the problems we encounter in our daily life.If what we hold in our hands is not a stone, but a flying bird, after throwing the bird, the bird will fly into the sky. There is no need to follow the law of the parabola, and you can fly freely in the sky, neither following your original plan nor breaking away from your original imagination.

The story of stones and birds is a story often mentioned by Chinese real estate colleagues in the past year, and it has also become a code word among colleagues.Whenever I see a piece of news about real estate on the Internet or in newspapers, I discuss it with each other on the phone or MSN: "Is this a bird or a stone?" The rules can be followed, and at the same time, you will generally know who the stone will hit and whether it will hurt; if it is a bird, after flying out, even the person who threw the bird may not know where it will land , what the result will be is completely random.

In fact, everyone holds something that is about to be thrown in their hands. You can decide whether it is a bird or a stone, and it will bring you two completely different feelings.
