Should one infer from this that people who don't teach physics don't really understand it?

Neither do I. I completely misinterpreted the whole situation.

Yes. I actually ran into my conceptual problem with Taylor's example, because I always blindly applied the definition of work as a dot...

I am glad for you that you never have misconceptions.

No, I do understand it. I just had this misconception about it, which I have finally clarified for myself.

Thank you for your detailed explanation. This is not even new to me, I have done it like this myself before. My question was actually...

Yes. Once again I posted a question without thinking it through. Everything is clear, sorry for the bother.

I wonder what the work actually represents in this example. Normally, I would say that ##W=\int{\vec{F} \cdot d \vec{r}}## is the work...

This is odd. I checked the masses and they were okay. I now checked them again, and they are not okay. I must have used the wrong mass...

This is problem 2.7 from Griffiths' Introduction to Elementary Particles. Here are the two reactions that I am trying to examine: (c)...

Yes, that is mine. I just cannot find anything resembling that one among Griffiths' diagrams. Or could it perhaps be this one:

This is problem 2.3 in Griffiths' Introducion to Elementary Particles. I have Griffiths' solutions, otherwise I would be completely...

Thank you. I find it always interesting to read recommendations and comments on books. I noticed that Susan Rigetti has chosen the exact...

The particular derivation I gave requires knowledge of complex analysis and is quite lengthy. I therefore thought that it illustrated...

Thanks a lot. This is a derivation that I can follow. For physics purposes it is of course much easier to look up the zeta function and...
