I don’t mean BETTER. That’s a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That’s just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

    Automatic watches and grandfather clocks. The way they kept track of time using only mechanical principles is crazy. How does my automatic watch recharge itself using only the movement from wearing it and keep accurate track of time. Grandfather clocks are cool because they’re so power efficient.

      They are very cool indeed. And the fact that you can have a century old watch on your wrist and it’s just as useful as a modern one. In fact I’m wearing a watch from the 50s right now!
