That graph animation is pretty mind blowing to watch, especially knowing it’s captured off real data not just the theory. All his videos are great in general.

- MichaelZuo 3y agoIt's really incredible to see. And probably the first ever visual demonstration of it. No wonder electrical engineering design is so difficult for real world, complex, circuits, if it takes roughly 8 cycles for the electrical properties and the wave motion to stabilize. The amount of resistors, transistors seemingly randomly piled up all over a circuit board makes a lot more sense now.

- mcmoor 3y agoI always wondered why digital signaling is always purported to be better than analog when analog can always carry much more data than digital. But maybe noise elimination of digital signaling is just too important.
- runnerup 3y agoDigital simplifies the design a great deal. Analog you have to worry about so, so many things. With digital, as long as the levels aren't too out of whack, you can "just" focus on the theoretical logic and ignore most real-world effects. I say "just" not only because the theoretical logic is still fiendishly complex, but also because there are still real-world effects and flaws in your components which both rear their ugly head often (all abstractions are leaky). You can never completely ignore the analog world, but digital design is almost always much, much simpler than analog for anything beyond rudimentary levels of complexity. Obviously if you're designing the silicon for digital components, you care very much about the analog reality of signals. But those silicon wizards are the ones who are building the digital abstraction of the analog world so that the rest of us can "safely" ignore it, mostly.
- lazide 3y agoDigital allows simple and easy reasoning and logic. Which allows perfect duplication, checksumming, repeating, etc. Something impossible to do with analog, due to the processing model. Digital is built on analog primitives of course.
- runnerup 3y agoI love all his videos. But this one is amazingly mind-expanding. Thanks to his previous videos and a fluids engineering background, I had the right intuition for what would occur...but holy shit his experimental method was so far beyond what I expected. I kept wondering how he was going to show us the level of detail he was teasing in the title and introduction, and seeing the resulting visualization was just so incredible and inspirational. Really he may be the best technical YouTuber for true nerds who don't want things dumbed-down but still want it to be reasonably accessible.
