Basics of Particle Physics: books and courses
Where to learn entry-level particle physics? Like most people, I have been hearing about words like "quarks, hadrons, leptons" since junior high school. However, I have never known the next…
Summary for 2023 — Physics (continued)
Quantum Information and error correction by Daniel Gottesman and Artur Ekert During January to April in 2023, while studying quantum error correction in the textbook reading session of our research…
Summary for 2023 — Physics
The effect of pandemic decayed away in 2023, so I attended many activities. This is the most dynamical year since the start of graduate school in 2019. I split the…
Memoirs: Polyakov, Migdal and Polchinski
I finished reading several memoirs of physicists this month. Two are Russian-born physicists, Alexander Polyakov and Alexander Migdal. One is the author of a modern String Theory textbook, Polchinski. I…
Modern Classical Dynamics by Polyakov at Princeton: Symmetry, Lagrangian and Hamiltonian Mechanics
I was so exciting to find a series of lecture videos on YouTube about Classical Physics by Professor Alexander Polyakov early this year. From the course website here or here,…
Kepler Problem
Today I suddenly realized that Kepler problem is easier than I thought. I first met this problem in high school physics class around 2010 and 2011, where we were simply…
General relativity: MIT video lectures
From middle July 2022, I started studying general relativity (GR) again. I use three resource at the same time: 1) Prof. Scott Hughes’s MIT’s physics graduate course 8.962, 2) the textbook…
Spacetime Physics by Taylor and Wheeler
Many failures and difficulty in understanding general relativity, quantum field theory, and conformal field theory I tried to follow the video lectures of the MIT course 8.962 about general relativity…
Into Rabbit Hole of Quantum Again
It has been half a year since my last post, and I forgot to post a plan for the year 2022. So first some recent updates about my physics study.…
Geometric aspect of classical mechanics
There are many approaches to classical mechanics. The first introduction in high school is intuitive and fit into our everyday experience: motion of a single particle is some trajectory in…
