The famous quotes of physics are as follows:

1. The laws of physics cannot be obtained by thinking alone, but we should also devote ourselves to observation and experiment. - Planck

2. The beauty of the equation is far more important than conforming to the experimental results. -Dirac

3. People who are stubborn about the old theory of light are best to propose experimental explanations based on its own principles. And, if he fails in this effort, he should acknowledge these facts. -Thomas. Yang

4. As long as movement exists forever, time will never disappear. Ancient Greek philosopher Aristotle

5. The task of physics is to discover universal laws of nature. Because one of the simplest forms of such a law is the invariance of a certain physical quantity, the search for conserved quantities is not only reasonable, but also an extremely important research direction. - Laue

6. The difficulties faced by physics will force physicists to explore and master some philosophical issues more deeply than their predecessors. I am more of a philosopher than a physicist.

Introduction to physics:

Physics is a discipline that studies the most general laws of motion and the basic structure of matter. As the leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, ranging from the universe to elementary particles, and therefore becomes the research basis for other natural science disciplines.

Physics began in the era of Galileo and Newton. It has become a basic science with many branches. Physics is an experimental science, and it is also a science that advocates rationality and values ??logical reasoning. Physics fully uses mathematics as its working language. It is the most sophisticated natural science discipline today.

Physics is a natural science that focuses on the study of matter, energy, space, and time, especially their respective properties and their relationships with each other. Physics is the knowledge about the laws of nature; more broadly speaking, physics explores and analyzes the phenomena that occur in nature to understand its rules.
