These are excellent books. I think that Shankar is sufficient for QM (and Sakurai is really not a great textbook to learn from, in my opinion). But you definitely need to be very at ease with special relativity and with tensor manipulation.Andreol263 said:https://www.amazon.com/gp/product/1466513179/?tag=pfamazon01-20
This book, so will suffice if i read Shankar? Or i will need to read Sakurai too?
That shows how picking books is subjective. That's why I never say that a book is great or a book is bad, I can only say that something is good or bad, in my opinion.vanhees71 said:I'm not so enthusiastic about Aitchison and Hey. I don't know Shankar's textbook very well. Sakurai, from which I learned QM in my introductory course lecture, is excellent.
Ok, but they also make a lot of effort to be pedagogical, I find.Andreol263 said:I Don't know, i picked up the Aitchison and Hey's book because it appears to have more content and good for self-studying, because this book has two volumes that summed up go to nearly 1000 pages!
Gauge theories are mathematical models used in particle physics to describe the interactions between subatomic particles. They involve the use of symmetries and mathematical fields to explain the behavior and properties of particles.
Gauge theories explain the fundamental forces of nature by using the concept of gauge invariance, which means that the laws of physics remain unchanged under certain transformations. These transformations correspond to the fundamental forces, such as electromagnetism and the strong and weak nuclear forces.
Symmetry plays a crucial role in gauge theories, as it allows for the conservation of important quantities such as energy and momentum. Gauge theories rely on the symmetry of physical laws to accurately describe the behavior of particles and their interactions.
Gauge theories are tested and validated through experimental observations, such as particle collisions in accelerators. Scientists also use mathematical calculations and simulations to predict and verify the behavior of particles based on gauge theories.
Gauge theories are considered to be one of the most successful and fundamental theories in modern physics. They provide a unified framework for understanding the behavior of particles and their interactions, and have been crucial in the development of theories such as the Standard Model and the theory of quantum chromodynamics.
