Quantum Mechanics: Fitzpatrick's Online Grad Course vs. Feynman & Sakurai

AI Thread Summary
Fitzpatrick's online graduate course in quantum mechanics is compared to Feynman's lectures and Sakurai's textbook, highlighting significant differences in difficulty. Feynman's lectures are designed for first-year university students and aim to foster a love for physics, making them less challenging than advanced texts. In contrast, Sakurai's book is recognized as a difficult graduate-level resource. Fitzpatrick's course is positioned as being more aligned with Sakurai's complexity, suggesting that it is intended for a more advanced audience. Overall, the consensus is that Sakurai is considerably more challenging than Feynman's introductory approach.

Just out of curiosity, how hard is Fitzpatrick's online Graduate version of quantum mechanics compared to the Feynman lectures and Sakurai's book?

I've never heard of Fitzpatrick's course, but the gap between the Feynman lectures and Sakurai is very very significant.
 
Sakurai by a landslide I'd imagine. Feynman's lectures were intended to instill a love of physics to a group of first year university students. They're not like actual advanced lectures.
 
Yep. Feynman's lectures are good for introducing quantum mechanics, but it's presented for first-year undergrads. Sakurai is an advanced graduate text, and a difficult one at that. Fitzpatrick's is definitely closer to Sakurai.
 
The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis, etc, it teaches QFT with only a passing acquaintance of ordinary QM you would get at HS. However, I would read Lenny Susskind's book on QM first. Purchased a copy straight away, but it will not arrive until the end of December; however, Scribd has a PDF I am now studying. The first part introduces distribution theory (and other related concepts), which...
I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
