Chapter 74 beauty and efficiency

Analyzing the movements of aerobics athletes with computers and robots reveals that those movements are extremely inefficient, but undeniably beautiful. A mechanical engineer at the University of Wisconsin, Searig, has spent more than ten years working on a fairly complete computer description of every movement of human beings, from walking to chewing gum, and the mechanics of bone and muscle operation.He said: As long as you know how humans move, you know how to help those who cannot move correctly.This is of great help in orthopedics, rehabilitation and athlete training. For example, for a person with a femur injury, we can input his height, weight, joint injury and other data into the computer, and the machine model can tell us what the patient's best walking posture should be, and how to use crutches.

The robot model designed by Seerig is like a real person. It can perform extremely fine movements. When it moves, we can know the sequence and degree of activity of each muscle, and then use these data to help patients or normal people. human action. Although this machine model shows the similarity between the human body and the machine, the human is still different from the machine.Seerig said: One of the principles of a good machine is to do the most work with the least energy, but it does not apply to people.We can't make every movement very efficient, this is purely for beauty. Human beings walk in a posture that looks beautiful to us, it is a subconscious movement.We once applied it to an aerobics athlete with a robot model and found that the movement of this athlete was very inefficient, but it was undoubtedly beautiful.It means that we are not computerized mannequins, that humans are imperfect machines; we are flawed, but beautiful humans.

A man who regards man as a machine will lose many beautiful things in this world.People who pay attention to efficiency in everything will not be able to experience many beautiful things.
