There is an ancient Chinese proverb which says “If you don’t forget the precedence, you will get instruction.” However trite the proverb seems, we can’t deny the fact that we ought to draw some lessons from past events by examining processes we have passed through. No matter how enjoyful , exciting, or suffering it is , experience is the best teacher inspiring us to develop the royal road which leads to our pursued goals.

All mankind civilization and technology achievements are evolved based on deposited knowledge from generation to generation. Newton's first law of motion which laid entire foundation for classical mechanics was named after English physicist Isaac Newton who introduced this great theory in 1687. As we all know, prior to Newton there were some other predecessors of note who contributed to inquiring the relationship between a body and the forces acting upon it. Aristotle , one of the greatest Greek philosophers, established general principles of change that govern all natural bodies. Although Aristotle’s view that “an external force is required to keep a body in motion” turned out to be a fallacy which prevailed some fifteen centuries after his death, His concept of violent motion led to the concept of force, is one of the most significant parts of physics. Then, Galileo, a premier scientist in the seventeenth century, developed the concept of inertia. Thus, contrary to Aristotle, Galileo concluded that objects could naturally remain in motion rather than come to rest at a point. Several decades later, Isaac Newton incorporated Galileo's result in his first law of motion--the law of Inertia. What makes the first law so special is that it was developed by the accumulation of research and knowledge of multiple generations of scientists. It is extremely important because it is the foundation for more powerful Laws two and three. As Newton himself famously said: "If I have seen further, it is by standing on the shoulders of giants." The experience...
