"Current" Events

I'm planning to teach a kid's class soon on basic electro mechanical stuff, and writing my own material. Old school me still thinks in terms of electron flow from negative to positive, but "current" teachings are that electrical current flows from positive to negative and that seems like the "path of least resistance". I'm sure I'll make numerous errors in swapping my world view. I'm likely opening a can of worms here, but can anyone WHO HAS TAUGHT KIDS offer any insight? TIA

I hope to avoid the "pandemonium" described at

In the scientific and engineering world, and in all the literature and books, everyone "knew" that in a circuit, electricity flowed from the positive battery terminal to the negative terminal. This was a well-established concept and any change to that concept would cause mass pandemonium.


  • Great idea so far. Go for it.

    No mascot.

    Nor any active robots except on Mars.

    FWIW It's always taught that current flows from positive to negative. And then they add the realisation that electrons physically flow in the opposite direction and then this part is ignored henceforth.

    Two of my all-time favorite platitudes from college engineering textbooks:

    1) It shall tacitly be assumed that... ( zero friction, zero loss, 100% efficiency etc.)

    2) It is left as an exercise to the reader to prove that... (Einstein was wrong, etc.)

  • 3) It's intuitively obvious to the most casual observer that ...

    Funny some part of my original post survived there.

    Now what prompted that one Phil?

    Still "No mascot."

    And "Nor any active robots except on Mars."

  • There are groups in the US government who care about this. You may want to contact this guy.

    There are other groups in the US government to contact as well.

    In general good to follow the Big blog by Matt Stoler. He talks about Monopoly issues.

    I really admire your company for many things. For a very interesting chip. For employing Americans, for not outsourcing, and for not taking vulture capital. For great customer service.

    In progressive politics (I run GreenMaps.US), there is a lot of discussion of solidarity economy networks, where we buy from other American companies.

    I had not considered "Buy American" as an issue in whether to use your chips or not, but it really should be front and center. Much like when we buy from Amazon, we are personally responsible for the evil Jeff Bezos does, or when we use Facebook or Twitter, we are supporting their censorship, when we buy from you, we are contributing to the good that Parallax does.

    Warm Regards

    Man, how quickly this thread went off the rails!
