Physics is the science that describes the interactions of mass and energy in the world around us. The Coursera course “普通物理學-電磁學、光學及近代物理 (General Physics (1))” offers an engaging introduction to modern physics, focusing on electromagnetism, optics, and the breakthroughs of contemporary physics.
### Course Overview
This course is structured into seven weeks, each focusing on a different aspect of physics. The first week begins with electrostatics, introducing concepts such as electric charge, electric fields, and Coulomb’s law. The instructor emphasizes real-life applications and historical context, making the material relatable and engaging.
In the second week, the course transitions to electric current, exploring the discovery of current, resistance, and Ohm’s law. The use of everyday examples, such as the electrical signals in human nerves, helps to illustrate these concepts.
The third week dives into the mysterious world of magnetic fields, discussing how scientists historically observed the relationship between electricity and magnetism, leading to the formulation of Ampère’s and Faraday’s laws.
Week four combines electricity and magnetism to introduce electromagnetic waves, highlighting the significant contributions of James Clerk Maxwell. Although this week involves some mathematics, the beauty of symmetry in physics is emphasized.
The fifth week focuses on optics, exploring the interaction of light with matter through reflection, refraction, and diffraction, among other phenomena. This week invites students to appreciate the wonders of the optical world.
In week six, the course covers the theory of relativity, discussing Einstein’s revolutionary ideas and their implications for our understanding of time and space. The famous equation E=mc² is explained in a way that connects it to everyday life.
Finally, the seventh week introduces quantum mechanics, the cornerstone of modern physics, discussing concepts such as energy quantization and wave-particle duality. The course concludes with a brief overview of atomic structure, providing a comprehensive understanding of the quantum world.
### Recommendation
I highly recommend this course for anyone interested in physics, whether you’re a beginner or looking to refresh your knowledge. The instructor’s engaging teaching style, combined with practical examples, makes complex concepts accessible and enjoyable. The course not only provides a solid foundation in physics but also encourages critical thinking and observation of the world around us.
If you’re ready to embark on a fascinating journey through the principles of physics, this course on Coursera is a perfect starting point!
