Preparation, I have often said, is rightly two-thirds of any venture Amelia Earhart (Last Flight, Harcourt, Brace and Company (1937)) It’s sad if you don’t have enough money when you genuinely want to buy things. It’s even more miserable if Read more…
Hi, guys๐. Thanks for coming. Itโs always great to have you here to exchange brilliant ideas. Although we are generous in spirit, let’s adopt a more precise and critical approach when diving into physics. I like to think of myself Read more…
This covers lecture 5 to 7. These lectures give us basic language to bridge between ‘Classical Thermodynamics’ and ‘Statistical Mechanics’. I guess those two fields will be merged from next lecture as ‘Kinetic Theory’. Question

This lecture is in the realm of art. I can’t add or remove any words in his lecture notes and lecture. My respect for him and his physics life. If I become a professor, I will start teaching undergrad students Read more…
Motivation In my undergrad, this part is barely covered. But scattering is not trivial part; remember how we found that the nucleus is bigger and heavier. It comes from Ruttherfold’s alpha scattering experiment. And scattering is also important topic in Read more…
Why I prepare these problems? Close your eyes, and try to imagine some simple geometries you can see daily. How was it? I hope you didn’t see your deepest fear. My mind says circle(sphere), square(cube), triangle. Actually, these geometries have Read more…
Question Imagine a 1D typical Quantum Mechanical configuration with infinite potential well (\( x<0\) ) and attractive delta function \( U\,=\,-u\delta(x-a) \). Let’s say there is a particle with mass m. In attractive delta function, we’ve checked mathematically there can Read more…

This loyally follows the content in <Theoretical Minimum; Quantum Mechanics> of Leonard Susskind. His guideline is very clear for physics major students. Contents are the essence of quantum mechanics, without a doubt. So I will summarize the contents with notes.
