    I’ve taken so many computer science classes and lectures but I still don’t know what it is, exactly, that makes us able to tame lightning and have it produce moving images that we can control.

    Like, I know how a transistor works, but not why it works. There’s just a disconnect between what science can actually tell going on between “what electricity is” and “making this little metal loop we can trap the lightning and enslave it to our will.”

    I have trouble describing what I want to know that’s missing so it probably is doubly hard to explain that thing I am trying to describe. 😵‍💫

      I think you’re missing what at my university is the course: Solid State Physics, followed by a manufacturing course that may contain a lab.

      This covers the physics of transistors and the basics from crystals, how to modify the properties of a crystal, and quantum effects. Then you will know how electricity affects a transistor (through field effect).

      Basically if you have two wires that are open, then run a live wire near these two wires, the two wires will close. That’s a very high level overview of a field effect transistor.

      Building registers and such helps. It’s very achievable… You can physically build memory or a nand gate on a breadboard

      I don’t know how I’d jump the gap from minerals to transistors, but I know how they’re arranged

    I don’t understand why entire statements come after octothorpes. I get hashtagging stuff and how it might help with organization, but I don’t understand why whole sentences.

    I’m not trying to be pretentious or “dang young people,” I just sincerely don’t understand.

    Other than that I enjoyed the post.

    To be precise we take powdered star-core only from medium sized stars, dissolve it, and grow it into a mighty monocrystal of highest purity, and then slice it up into thin chips

    Any space aliens that see or hear radio waves that find Earth as it is today must be thinking, “WHAT FRESH HELL IS THIS?”

      I mean, in reality, any alien species that can receive and decode our infintesimally small signals is almost certainly thinking, “lolol look at those apes. They’re still playing with rocks.”
