    A Testing antimatter fundamentals

    That is a silly and false dichotomy. The spending alternatives are not between antimatter research on one hand and between unemployment and gambling on the other. Your response is not an indication of an intention to have an informed discussion on this topic. As I mentioned in my earlier reply...

    A Testing antimatter fundamentals

    There was recently the experimental confirmation that antimatter falls down. That was using anti hydrogen, so that is two body. The institutional roadmaps you mention are generally scheduled at capacity. So adding more experiments would require eliminating some. Which specific experiments would...

    I What is the zero point for Potential Energy and how to find it from integral limits?

    That is correct, but then this is not a change of variable, this is a completely different integral so it does not make sense to say that they are both equal to the same ##\Delta KE##

    I What is the zero point for Potential Energy and how to find it from integral limits?

    This makes no sense: $$\int_0^{h}= \ ...$$ is not a well formed expression. If that really is the expression in your book then you need to get a new book. You need to not be sloppy. Also, define your terms here. I assume ##m## is mass and ##g## is the gravitational acceleration. What are ##h##...

    I What is the zero point for Potential Energy and how to find it from integral limits?

    Your change of limits is incorrect. Also you are forgetting the differential, and forgetting to write clearly what variable ##F## is a function of. Basically, you are being very sloppy and your confusion is a result of that sloppiness. Set up your variables clearly and do your substitutions...

    I On the physical meaning of Minkowski's spacetime model

    Yes, from that you can derive the fact that in the rotating reference frame a light beam traversing clockwise or counterclockwise will give different times.

    That is correct. A light beam traversing clockwise or counterclockwise will give different times.

    I On the physical meaning of Minkowski's spacetime model

    Yes. This is also the reason why Einstein synchronization is not possible (globally) in a rotating reference frame

    Why are Physicists so informal with mathematics?

    Another ill informed generalization. Some medical education DOES involve experimentation; I know: I coauthored papers where medical students actually performed and published experiments. This is universal in combined MD PhD programs. How is that for elitism? You want to dismiss the science-ness...

    Why are Physicists so informal with mathematics?

    Well that is another false generalization. There is a huge body of experimental work in medicine, psychology, biology, materials science, and many other scientific fields. Physics does not have a monopoly on the scientific method. Again, this is not unique to physics. As someone with your...

    Why are Physicists so informal with mathematics?

    Then how can you make these ludicrous assertions specifically singling out physics instructors? You should know better

    Why are Physicists so informal with mathematics?

    What is your background? You seem to be completely ignorant about how teaching works. Most instructors (physics, history, any subject) teach at some educational institution as part of a broader curriculum. Their job literally is to pass on a specified subset of the knowledge they have to their...

    Why are Physicists so informal with mathematics?

    I think that you are missing the point in your question. As a physics instructor I can tell you for certain that different students learn things differently. The idea that a solid grounding in the mathematical derivation will generally lead to UNDERSTANDING is incorrect. Some select students...

    Why are Physicists so informal with mathematics?

    @Sassan frankly, this is a ridiculous assertion. There are many gifted and respected physics instructors. The fact that not every professional physicist is a good physics instructor does not imply some elite community disdain for others. Good physicists who are gifted instructors are celebrated...
