   Can you explain results of double slit experiment (when single particle creates interference pattern) to us, mere mortals, please?

   Book describes double-slit experiment but does not explain it. I read that when I was student 20 years ago. So, WHY single particles are developing interference pattern when sent one by one? Shut up and calculate is not an answer: https:&#

   English language is foreign for me and physics is my hobby, so you can safely assume that I'm noob in physics and use plain English and simple explanations. I need much more time to read in English that in my native language, especiall

   I found papers: they are calibration results of LIGO detectors. I read them years ago, so I forget anything except that they found systematic temporal variations across day and year, and they are using long 2km arms. Their latest paper: ht

   Yep, field is covered by formulas with pretty high accuracy. AFAIK, the only practical field when correction is needed is GPS satellites, but correction is extremely low. However, our vision is moot. Video above just opened my eyes.

    C is high-level language. It's portable across variety of platforms, while low-level languages are tied to hardware platform. Assembler is low level language.

    It's looks like we are talking about differences of use of physics in practice versus advancing of physics as science. No doubt, if I will need to calculate something, being paid for that, I will use proven formulas. Totally agree with

    I had good teacher of physics. He always told to us that we must fully understand what happens at physical level, and only then start to calculate. „Shut up and calculate“ is not an answer for me. I also don't feel frightened not knowi

    Of course. Can you provide an explanation of double-slit experiment using Standard Model of QM?

    Yep, you are right — 3D version will be very different. Why not to conduct such experiment in space, where 3D version can be constructed with ease? Moreover, electromagnetic waves are very different from sound waves, so physic process invol

    IMHO, it's better explanation than God or half-dead cat. If you have better explanation, then film it, please — it will be very helpful.

    I suggest to read Gemba Kaizen books. Yes, it is hard to understand first, but then you realize that Toyota Way is like 3D printer — add only what is needed right now, do it fast, be precise. So yes, you are right — Toyota Way is not viable

    Of course, it is rare that same bug will pop up twice, but bug demonstrates areas which are not covered by tests, so new test(s) will cover these areas and will catch an other bug(s).
