What is the purpose of our study of physics?

Physics is a basic science aimed at studying the basic laws of material structure and movement in nature. It is also a discipline that plays a leading role in other disciplines and is the foundation of modern civilization. Physics has become an independent subject since Newton's masterpiece (the mathematical principle of natural philosophy). This is a subject that studies the laws of nature. We find laws from the chaos of nature, apply them, and then explain all the phenomena in nature. For example: 1, TV, mobile phone, computer, Internet. 2. Modern medical equipment such as CT, MRI and X-ray. Cars, high-speed trains, planes, ships and warships are all based on physics. Anyone who intends to engage in any kind of technical work needs to understand the basic principles of physics, so as to understand the basic principles on which our modern high-tech society depends. And physics has also promoted the development of human society in the future.
