Understanding Modern Physics I: Relativity and Cosmology
The Hong Kong University of Science and Technology

I am thrilled to share my 100th course certificate. My journey to Coursera started in 2017, it has been 5 years since I got my first certificate. For this 100th certificate, I deliberately chose this course “Understanding Modern Physics”. I would like to express my deepest respect for Relativity, which is for sure the most beautiful theory ever created.

Almost every video clip in this course will rock your world. The first 2/3 of the course focuses on the Special Relativity. Special Relativity will reconstruct all of the concepts that you seem familiar: time, space, length, geometry, momentum, energy. It challenged beliefs that everyone else took for granted.



Contributions from many great physicists and scientists become the cornerstones and treasures of the modern physics. It is not only about Einstein, you will learn Lorentz Transformation, and Schwarzschild metric, but also find the “shadow” of Maxwell equations from electrodynamics. If you go deeper, quantum mechanics / gravity, thermodynamics, and many are also relevant.

To fill the gap between Newtonian and Special Relativity, the course smoothly moves its focus to General Relativity. Assuming the equivalence of gravitational field and acceleration is ingenious. Understanding gravity is critical here. Black hole is fascinating and probably will be out of your imagination.

The last part is about cosmology. It is about our universe. Its origin, evolution, and future. There are a lot mind-blowing WOW moments. While human beings are so small, our journey to explore the universe is gorgeous and amazing, our lives are very worthwhile living.
