There is physics everywhere. Everywhere you look there is a working atmosphere of physical phenomena in play. One example of physical phenomena is the art of fighting, or self-defense. The forms martial arts(self-defense) is Wu-Shu and for sure it is physics based. I think, that the body of a human being is the experimental lab where two or more bodies can experiment in themselves. Trying out different types of moves on each other through the force of motion, and reversible forces of gravity a group of Wu Shu students can do a lot of combinations of tactics that seem endless. There are many unique combinations of motions in the martial arts, and there seems to be physical movement in about mostly every kind of motion in the universe. The human body, by the way, is a laboratory where humans can experiment with their minds, and exercise self- control of their anger, rage, and emotions. This art is one of the most ancient forms of fighting and was trained by the ancient Shaolin temple in China. The physics behind the arts of fighting is relatively simple, there is a opposite force against you, and you try to use that force in your favor. For example, there is someone about to punch you, and you use the force of acceleration from the fist to turn it against the opponent in a way to submit your opponent; and have him in an uncomfortable position. This process contains physics because our arms, shoulders, knees, and legs have pulleys and levers in them, and can be described by Newtonian physics.
Everything from Martial Arts, to the motion of the planets can be described by Newtonian physics. Newtonian mechanics also plays a role in the physics behind Martial Arts(Wu Shu). Although the human body can withstand the force of motion, there are always limitations to what it can take. And, the Wu Shu can be used in a dishonest and evil way. People can use knowledge of Wu Shu for good or evil. People can use it to protect their families, or to cause trouble in their communities.
I think, the only useful thing about Martial Arts is it’s self-defense mechanisms, and being able to defend oneself physically against attackers who try to do harm on your family, and friends. I’m afraid there are people in the world how will only twist knowledge from the ancients and use it for doing evil, and causing havoc. They do this because they want to control the world, and for lust for power. They can’t see their lives because they have been blinded by evil ambitions, and selfish wants, that they can’t see their own lives because it is corrupted by these wants. We, as human beings live in a society of thugs, robbers, idolaters, the homeless, and people of the like who cannot stand in the current situation of things because of the evil man has one as a result of humans selfish ambition to have more, and more things, more material wants, and not concentrate in their spiritual welfare.
I hope, as many philosophers, and poets wrote, for a renewed life where there is no pain, no more violence, and no more suffering.
