The Character of Physical Law

In a television lecture originally provided by Cornell University and recorded by the BBC, Richard Feynman provided an overview of the chosen law of physics and focused on a common immutable principle. From the beginning he tends to discuss his graciousness in the final decision of all science laws rather than the importance of physics "finding out how wise it is ... how to pay attention wisely" He insisted. And briefly. The essence of the law of physics is not the paper on the most important achievements of modern science but the statements of the most remarkable thing in nature. Feynman's wise approach, his wisdom and enthusiasm makes this an unforgettable exhibition of scientist's craftsmanship. The law of gravity is the main example of the author. He uses it to show the basic interaction between mathematics and physics about his discovery details and his mathematical characteristics. He thinks that mathematics is the key to every science law system. It suggests that if it is possible to complete the structure of the scientific theory, the result will be a comprehensive set of mathematical axioms. Then, considering the principles of classical and modern physics development, conservation, symmetry, and time irreversibility, Feynman has developed a unique analysis of the process and future of scientific discovery. Just like reflection of other words, "the characteristics of physics" also has special value to prove actual thought.

A prominent feature of the physical law is that Feynman easily covers a wide range of physical fields - for example the role of universal gravitation, the relationship between physics and mathematics, and the role of symmetry in the laws of physics. But it is important to explain clearly that he is equally good at discussing the relationship between the history of these topics and daily life and why people are interested in them. It is this combination of skills that allows him to avoid excessive abstraction and philosophical thinking, which is a common trap when seeing the overall situation.

As Wilczek pointed out in the preface, there have been many things in physics since 1965. However, the nature of the laws of physics is very good today. My favorite chapter is the symmetry of physics. Feynman first pointed out that symmetry seems to appeal to human thought for aesthetic reasons. But he chose to emphasize the symmetry of the laws of physics itself. For example, some laws may be temporally and spatially symmetrical, but not necessarily scalable. In some cases, the meaning of these symmetries is more prominent than others. But the important point is that by focusing on these basic rules of the game you can understand the characteristics of the physical law they apply.

Richard Feynman's "Physical Law Nature", which was published in 1965 and is currently being reissued by the Massachusetts Institute of Technology, Frank Wilsack's Preface, stands out as an early example of achieving this goal. This book is based on a series of lectures by symbolic physicists at Cornell University last year. But this is a multilayered work and Feynman clearly shows that he is inspired by another lecture at the California Institute of Technology in 1961 and 1963. These will continue to be his most famous work: Feynman physics lecture (reviewed here)
