    I Need a layman's explanation for how scientists contain antimatter

    If they said that magnetic field consits of electrons and protons then yes, they are wrong. But I know they didn't say that, it's just you who misunderstood them. And again no one said that. Drop that attitude. The most basic thing - pop-science books are not meant to learn things from, they...

    I Need a layman's explanation for how scientists contain antimatter

    So you're here not to learn but to sell your vision of Nature? Sorry, PF is not for that. Besides, keep in mind that you are talking to physicists that know way more than you, so you should tone down a little bit. There are no electrons in magnetic filed. Wiki is not a good source when it...

    I Need a layman's explanation for how scientists contain antimatter

    And as been said, this is nonsense and does not logically follow from article you cited.

    I Rolling without slipping down an inclined plane

    But no one said that it's static friction because it has constant value. Kinetic friction also has constant value.

    Classical Textbook list for self-study?

    So? Spacetime is four-dimensional at least, and this is something that human brains can't comprehend visualy in general. Very important part of learning advanced mathematics is to rebuild your intuitions and built non-visual means of thinking about stuff. It's painful, but you have to do that to...

    I QED question: Photons absorbed and emitted by electrons

    Well, I paused for a while after reading the first chapter (I want to finish his group theory book first), but some people say (well, @vanhees71 says :oldbiggrin:) that Zee tried to fit too much in his nutshell and it didn't end up well. It may be a good read, but after you know something on the...

    I QED question: Photons absorbed and emitted by electrons

    Well, one usually starts learning QFT from QED so o0) Anyway, if you really want to delve smoothly into technicalities I recommend Klaubers Student Friendly Quantum Field Theory. It focuses on QED only, most of the derivations are outlined in great details and Klauber devotes one whole chapter...

    A Implications of quantum foundations on interpretations of relativity

    So can you give any example of paper on HEP, relativity or cosmology written in last, say, 30 years that explicitly uses relativistic mass? I know that some people use it in teaching, but teaching physics should prepare students to use physics in their work and I see no point in teaching...

    A Implications of quantum foundations on interpretations of relativity

    And this is not true - relativistic mass is not used in physics for ages. See this insight article: https://www.physicsforums.com/insights/what-is-relativistic-mass-and-why-it-is-not-used-much/

    I QED question: Photons absorbed and emitted by electrons

    I would say it's contradictio in adiecto.

    I QED question: Photons absorbed and emitted by electrons

    "Not meaningfull" is something different than "unknown". For example, where is the 'north' direction on the north pole? Do you think it's meaningfull to talk about that?

    I Problem of time in quantum field theory?

    Sorry, but I don't think that any of that makes sense at all. The question was: what does it mean that "in string theory there is no difference between time and space".

    I QED question: Photons absorbed and emitted by electrons

    If you are asking in the context of virtual photons, then this article is a good start: https://www.physicsforums.com/insights/misconceptions-virtual-particles/

    Classical Textbook list for self-study?

    These are descriptions in english. Physics describe Nature in language of mathematics, and there really is little room for any simplifications. And it's your problem that you don't have enough background in maths, not Natures or physics.
