Understanding Modern Physics III

Simplicity and Complexity

Yi Wang

The 20th century was known as the century of physics. In the past 120 years, concepts such as space, time, energy, entropy and particles were understood to much deeper levels. New paradigms of thinking such as relativity and quantum mechanics emerged.

This course is the third course in the Understanding Modern Physics series, which covers an introduction to action principle, fundamental particle physics, entropy & information and complexity. This course offers a broad view between simplicity and complexity, to complement the first and second course in the Understanding Modern Physics series.

Reviews summary

Deep dive into modern physics concepts

According to students, Understanding Modern Physics III offers a profound conceptual understanding of complex topics, rather than focusing on mathematical rigor. Learners highlight Professor Chan's remarkable ability to simplify complex ideas and his enthusiastic delivery, making the course a truly thought-provoking experience. It excels at providing unique philosophical insights into modern physics, particularly regarding entropy, information, and complexity. However, prospective students should be aware that the course assumes a very strong foundational knowledge in physics, as it can feel fast-paced and abstract without sufficient prior background, requiring significant self-study for some.

Prioritizes ideas; lacks extensive mathematical derivations.

"A good overview, but sometimes felt a bit too high-level, skimming over mathematical derivations that I would have preferred to see."

"It's not a course for problem-solving, but rather for conceptual understanding."

"My main feedback would be for more interactive elements or perhaps some supplementary problem sets to truly solidify the understanding..."

Instructor simplifies complex ideas with clarity and enthusiasm.

"The instructor's explanations are incredibly clear, making complex topics digestible. I particularly enjoyed the segments on entropy and information..."

"Absolutely brilliant! The way Professor Chan ties together quantum mechanics and general relativity, even without going into the full mathematical rigor, is masterful."

"Professor Chan's enthusiasm shines through. The way the professor simplifies complex ideas without losing their essence is remarkable."

Offers a unique, thought-provoking philosophical approach.

"This course beautifully connects deep physics concepts with philosophical ideas, truly living up to its 'simplicity and complexity' title."

"The discussions on complexity were mind-bending in the best way. This series is a gem for anyone curious about the frontiers of physics."

"The connection between entropy, information, and the universe's complexity was fascinating. It really encourages you to think deeply about the universe."

Covers many topics; pace can feel rapid.

"The course has interesting ideas, but I struggled with the pace and the depth. It felt like it was trying to cover too much without sufficient detail..."

"The lectures jumped between topics quickly, and the explanations often felt abstract without enough concrete examples."

"I had to do a lot of external reading to keep up."

Assumes a very strong background in physics.

"It assumes a solid background in physics, which is fair for a 'III' course."

"I found this course extremely challenging... It's probably best for advanced students."

"it presumes a *very* strong background in physics, more than I anticipated. I had to do a lot of external reading to keep up."
