What kind of teacher is regarded as a master is not a fraught.

My first listen to Mr. Beam's class, is l939 in Guangxi Yishan, listening to him for the University of Physics in the second-year students of the "mechanics" (ie, theoretical mechanics) class. Before class, I heard that this course should be told from Newton's three laws of motion I am very disappointed. Because of Newton's law of motion, I have learned four times (junior middle School physics, first-year physics of senior engineers and second-year applied Mechanics and college first-grade general physics), thinking that they already know nothing to learn. And I read more than 10 books on modern physics before I went to college, and I knew a little bit about relativity and quantum mechanics, and I was eager to skip Newton's classical theory 250 years ago and go straight to the new physics of the 20th century. Popular writings I didn't think I'd heard Mr. Beam's first class. I felt that my thoughts were completely wrong. The original complacency was shattered.

The most important feature of Mr. Bundle's lectures is: In an inspiring, thought-provoking way, the emphasis and depth of the basic physical concepts and principles, so that students can understand the entire theoretical framework. He embarks on the natural phenomena that he sees everyday, and makes a thorough analysis of the basic concepts and principles through a high degree of abstraction from various sides. and take pains to use a variety of readily available examples, in layman's argument so that students can follow to grasp the basic concepts. He lectures neither the handouts nor the designation on the blackboard nor the neat outlines for the students to transcribe, but only the simple and vivid language from the familiar phenomenon to clarify the physical theory and thought. He behaves casually and bluntly, likes to walk around in the classroom and to talk on the desk.

The first lesson of mechanics he first talked about the motion of the object, then the speed, the average velocity, and the instantaneous velocity, thus introducing the mathematical limit and the differential concept. Then the emphasis is on the movement, not the movement itself needs "cause". The so-called reason refers to the outside influence, can be called "X" or "Ghost", Newton called it "Force". Aristotle, formerly the Greek philosopher, thought that the movement of objects always required a catalyst to propel Galileo and Descartes and found that it was only when the state of motion changed that there was an external influence. In this way, he contrasts the ancient movement view with the modern movement view, and integrates philosophy and physics into one.

This class I can hear God, feel enlightened spirit to get a great enjoyment. In this way, Mr. Beam took the three laws of Newton's motion for one months and its memorable. In contrast, I used to learn four times the three Laws of motion and two times calculus (high school first time), but also skillfully use Newton's law to solve a lot of mechanical problems, but for the movement and force did not form a clear physical concept, is actually indefinitely. So I began to really understand what is called theory, what is the principle ... Through Mr. Beam's class, I have a thorough understanding of the physical content of the basic concepts of Newton's mechanics. The completeness and consistency of the classical physics theory began to appreciate the importance of basic concepts and fundamental principles, and began to develop the habit of disquisitions problems ...
