This plant itself is motionless, but it can move its genes with the help of wind, water and animals. For example, flowers produce nectar, attract bees and let seeds move on bees. Plants form fruits and attract animals to pick them. Animals eat the pulp and throw away the stone, and the seeds move. The seeds of lotus root float on the water with the help of lotus flowers and move with the current.
Vultures are the most efficient animals in nature. It produces hot steam after heavy rain in the savannah. Vultures can glide easily in the sky with open wings, and can land vertically without any difficulty when they find food. (Jobs wrote an article about vultures. He studied vultures in order to find equipment to improve the efficiency of human movement, so he made a computer. )
With the development of history, the physical world began to migrate to the information world, and human beings can communicate indirectly with the physical world through information. For example, in Greek mythology, Passieux tried to kill Medusa, but he couldn't fight Medusa face to face, because Medusa's eyes could petrify anything, so he polished the shield, used it as a mirror, obtained Medusa's position information, and finally defeated her.
Another example is the elephant in Cao Chong. Cao Chong didn't directly hang the elephant and weigh it. Instead, first catch the elephant on the boat, write down the information of the water level scale, and put stones on the boat after catching the elephant to make the boat reach the same water level scale. The weight of an elephant is obtained by weighing the stones on the boat. Cao Chong obtained the weight of the elephant indirectly through the information of the scale.
At the beginning, human beings transmitted information through physical displacement. For example, the messenger from Athens, in order to convey the message that "we won", ran 42 kilometers from marathon to Athens. Later, a method of transmitting information without relying on physical movement was invented, such as beacon tower transmitting information. Although the beacon tower stands still, it can transmit information thousands of miles away by broadcasting beacon smoke.
After the informationization of the physical world, communication (information movement) replaced traffic (physical movement). People don't have to get information face to face. Although thousands of miles apart, it feels close at hand. Interestingly, 2.5 million years ago, apes went out with stones, but today people go out with mobile phones. The history of civilization is a history of migration from the atomic world to the bit world. In the bit world, without the bondage of atoms, human beings feel unprecedented freedom. 1 second can reach anywhere on the earth (get local information through video and telephone). Futurists predict that human beings will complete their digitalization in 2045. They can store their memories on a USB flash drive, and then put them into a new body after the body ages to realize eternal life.
Financial history is also a history of pursuing liquidity, but it is only a movement of wealth. The initial business of mankind was barter, but the flow efficiency was too low, so there was money. As a medium (media characteristics: carrying information, allowing information to move relatively), money carried wealth information. From shell currency, gold and silver currency to paper money, the liquidity of wealth is constantly developing. Now, a bank card can carry thousands of wealth information. Future wealth is developing in the direction of being completely divorced from entities, such as bitcoin. In addition to space movement, wealth can also move across time. For example, a loan is to move future money to the present.
But are we really free?
Philosophers divide freedom into two kinds: positive freedom, that is, what I can do freely; Negative freedom, also called negative freedom, means the freedom not to do something. Compared with these two freedoms, the latter is more precious and rare. For example, I don't want to be disturbed, I don't want to be trapped, I just want to be quiet Traveling abroad is looking for positive freedom, while staying in private space is looking for negative freedom.
Man has been pursuing freedom. Freedom gives them more choices, but this era is characterized by unlimited choices. Choice is not scarce, but like a flood. People want water to drink because they are thirsty, but what they give you is not a glass of water, but a terrible flood. Under this freedom, everyone is at a loss, there are new news every day, everyone is highly interconnected, and greedy anxiety is everywhere.
Infinite freedom = no freedom. Astronauts should be extremely unaffected by gravity in space, but weightlessness is terrible. In the state of weightlessness, human beings can't control their movements, and they are at a loss and can't find their direction.
Nietzsche said that our eyes are our prison, and our eyes are the walls of the prison. A person's life is to polish his eyes and widen the prison wall, but you are still in prison after all, and freedom is relative and dependent.
If freedom floats in the wind like a feather, it is involuntary. You may be disturbed and captured at any time. Freedom should be like a bird. Although bound by gravity, you can spread your wings and fly by yourself.
In this era, if you want to be free, you should get out of the torrent of information, get off the line from the Internet, reduce the efficiency of mobile, find a small corner and be yourself.

After listening to the theory of relativity in Wu Dong, I was impressed by Wu Bofan's wisdom and learned from him.
