I fell into a depression for a while so nothing, but recently my sense of curiosity is coming back. I’ve been reading about climate change. I feel like I’ve been bombarded by all sorts of information over the last few years and want to sort out at least a little of my confusion.
Oh and I got a VR headset and have been learning how to use the 3d paint app.
If you zoom in really hard into how “electricity” works you find it mostly has to do with electromagnetic fields.
If you zoom in on electromagnetic fields you get quantum mechanics.
If you zoom in on quantum mechanics you find a lot of disagreement, basically the best scientists today still don’t fully understand our observations.
So in essence we still don’t really understand electricity.
At best you get physics that describes phenomena like vanderwaals forces describes the magnet force but they don’t explain how to phenomena exist, how those forces form.
Or i am just to stupid to understand the current scientific meta. I have always been dissatisfied with how unrevealing physics was and how much questions it never answered while getting a passing grade though.
The real world application fields convert these theories into smaller easier to understand rules that you can hold, touch, taste, and smell. A microchip groups a ton of sub micro scale components working together as a factory to produce a device that is used to make another device , etc. Each one of those sub scale components was meticulously designed to work in a certain way using well understood rules. We likely do not have the understanding of lower level quantum-ish magic that makes it work, but we do know how to build real things with our simpler rules.
No, you’re pretty accurate! As a physics geek I’ve always joked that electricity is the closest thing we have to real life magic and all of our computers are essentially running on magitech 😂
I thought electricity was just a stream of electrons flowing in one direction like a provoked stampede.
Did Bill Nye lie to me?
Bill Nye was describing a direct current (DC). But most houses use alternating current. With an alternating current (AC), the electrons are jutting back and forth rapidly rather than flowing in one direction, and the rate of this depends on the Hz (frequency)!
Yes he did. Its the holes. The holes move.
But beyond circuits I, the OC is right. It quickly gets into field theory, where electricity in wires is just a special case.
its 100% in any meaningful sense of the word move the electrons that move, but thanks to ol’ benny franks we have an ass-backwards roundabout way of describing the relative motion of stationary proton “holes” compared to electrons which are- well, more teleporting than moving, frequently (if you’ll pardon the pun). holes move in the same way that water pressure is analogous to voltage: there may be mathematical and maybe even some physical comparisons to be made, but the conceptual framework is fundamentally an analogy, and in the case of “hole flow” a fudged up cya excuse for not updating the damn convention when the mistake was discovered. hurrumph.
holes flowing… protons with free motion? in a solid wire or semiconductor? you mean a plasma.
is there a physical constraint one could apply to matter to cause “holes” to flow while electrons stay put?
I was reading legal cases of divorced parents, one who wants to vaccinate their children and the other who doesn’t, this weekend. The judge always sides with the parent who wants to vaccinate.
strange, that. government conspiracy no doubt.
Read in a travel guide about the modern history of Cyprus, and it was not what my super-superficial knowledge made me expect to read. Did not dive into a rabbit hole though.
Learning more about Ancient Cahokia.
I learned quite a lot yesterday about the creation of Call of Duty licence by the Infinity Ward studio. Quite interesting to see how the story unfold, and how defining to the whole industry a single studio could be
I’ve been reading a lot about personal finance. The Millionaire Next Door really opened my eyes.
I also learned about leading and lagging indicators and thought that was cool!
Small advice: take that book with a grain of salt. The author took advantage of a specific market, what he did is not achievable everywhere for everyone
You mean it only applies to the US, or something different?
