Although copies of the lecture notes are provided here, it is highly advisable that you should take note in the class. Passing the information from your eye, through your brain, and to your hands will help you to retain the information much better. You should also note that there might be small changes in these notes as compare to the one presented in class.

- Here is a recent book review from NYT on a good book by physicist Brian Greene with an interesting musing on entropy and the end of time.
- When you have some time during Spring Break, you might want to read throught this interesting (but long) exposition on the history and development of the 2nd Law of Thermodynamics by Stephen Wolfarm.
- Here is also a copy of the paper written by Sadi Carnot on heat engines and the embryonic form of the 2nd Law of Thermodyanics.
- Here is the second sample example which you can practice on for your exam: link.

- Here is a great video from Vertasium on the priniple of least action underlining a general physical understanding of the natural world.
- Chapters 34 & 35 (Lecture #14)
- Chapter 35 & 36 (Lecture #15)
- Here is a link to a brief description of the Poisson's spot. If you have a small telescope at home, you can also try to recreate it following the description in this article.

- Here is a link to a recent article on how new measurements of the muon's magnetic anomaly might bring new understanding of nature beyond the Standard Model.
- Chapter 37 (Extra slides for Special Relativity) Topics not included in lecture: Twin Paradox, Relativistic Dopper Effect, Space-time diagrams, and an intro to General Relativity are here. For those interested in learning about these topics, please read them over.
- Good introductory articles on General Relativity for those of you who are interested from Einstein online, Max Planck Institute for Gravitational Physics.
- Chapter 37 & 38 (Lecture #22)
- Chapter 38 & 39 (Lecture #23)
- Here is the article to a recent quantum interference experiment with large bio-molecules. As Richard Feynman once said: "The basic element of quantum theory is the double-slit experiment. It is a phenomenon which is impossible, absolutely impossible to explain in any classical way and which has in it the heart of quantum mechanics. In reality it contains the only mystery ... the basic peculiarities of all quantum mechanics."
- Also, here is an informative video from Veritasisum on how the Path Integral formulation of Nature (i.e., a natural system explores all possible paths simultaneously between two points in space-time) and the Principle of Least Action helps us to develop an unified (classica and quantum) view of Nature. At the heart of it, you will recognize the familiar phenomena of wave interference.
- Here is also an interview of Louis de Broglie stored at the Institut national de l'audiovisuel (INA) (National Audiovisual Institute) which is a repository of all French radio and television audiovisual archives. A YouTube version of it with English subtitle is here.
- Chapters 39 (Lecture #24)
- Chapter 39 & 40 (Lecture #25)
- A derivation of average E in Blackbody Radiation (in pdf format) The math trick which I used to sum the infinite series is a good trick to learn.
- Chapter 40 (Lecture #26)
- Here is another set of sample problems on modern physics for you to practice on.
- Chapter 40 (Lecture #27)
