> Electronics is about building useful circuits. This is just factually inaccurate; electronics is the field which relates to control/emission of electrons. If you build a "useful circuit" which does not use any active components, you aren't doing electronics. If you're applying solid state physics to model transistor behaviour, you're doing electronics. The terminology has absolutely nothing to do with levels of abstraction. I understand what you're saying, and agree that there is a broad range of levels of abstraction within electronics, but the division in abstraction is unrelated to the division between electrical and electronic engineering.

There are multiple definitions of electronics. If you are physicist you might envision electronics as control of emission of electrons. If you are an actual engineer you will have very different definition and understanding of what electronics is. It is like calling computer scientist experts in software development. No, knowledge of algorithms is far, far from software development which is also about human interaction, project organization, and many, many other things. Go google "electronics definition": >noun >the branch of physics _and technology_ concerned with the design of circuits using transistors and microchips, and with the behaviour and movement of electrons in a semiconductor, conductor, vacuum, or gas. So no, it is not obviously just about control/emission of electrons.

  > the branch of physics _and technology_ concerned with the design of circuits using transistors and microchips, and with the behaviour and movement of electrons in a semiconductor, conductor, vacuum, or gas. Yep; it is explicitly is talking about either active devices or literally cases where the topic of focus is control/behaviour of electrons. > If you are physicist you might envision electronics as control of emission of electrons. If you are an actual engineer you will have very different definition and understanding of what electronics is. It has nothing to do with the level of abstraction at which you're working, which is my entire point; whilst an engineer may very well not be considering the behaviour of electrons in day to day work, if she is doing electronics, she is working with devices/technologies which involve the control/emission of electrons. If she is working on, for example, an induction machine, she is not doing electronics. Again, I'm not contesting that people work at different levels of abstraction within a field, just pointing out that the term "electronics" as opposed to "study of electricity" has absolutely nothing to do with abstraction; it refers specifically to whether <active devices/transistors/semiconductors/control and behaviour of electrons/whatever you want to call it> is involved.
