Hi. I am an undergraduate physics student and have just begun lectures on elementary particles and the Standard Model. At the moment I really know nothing about this branch of physics and am looking for recommendations on a textbook which introduces the subject well. Thanks

The axiom says: "The interaction between two observations is constrained by causality |x-y|^2 <0 \Rightarrow [\phi(x),\phi(y)]=0 " But |x-y|^2<0 is always false that means the if the condition applies then by simple logic the consequnet of the condition can occur or not occur, I don't...

Hey I either have the worst physics textbook in the history of physics textbooks or i can't understand a topic.I'd appreciate if you help me decide which is it. (Pic related is the image of the example) First let's agree on the symbols let's call angular velocity: \omega = \frac{rxv}{||r||^2} ...
