This is one of those things I never gave much thought but is super facinating. The technology connections youtube channel just did a video about this, too: http

I was just going to post this. Others have given some of the math and technical explanation below but if you would like to see this in action with a bit more of the history behind it all, I highly recommend this video.

The TC video was good, but the link here sure is a faster way to learn the same basic information!

What age range is this channel's target audience? The slow pace and sophomoric description of 2 channel audio at the beginning makes me thing it is aimed at a young audience.

    It's not playback speed that's slow. It's the sophomoric definition of stereo. It's the absolute dragging of the feet to deliver that definition that isn't even a good description of stereo.

  I'm 30 or 40 years old, and this is one of my favorite youtube channels. :)

    I am also 30 or 40 years old. I'm Schrödingers millenial. I quite enjoy the delivery of technology connections. A nice change of pace imo, compared to other youtubers that edit out every millisecond of quiet time between words and sentences. But I'm not watching the videos to learn new stuff either

      Slower videos just means they last longer, and that I can keep up with them while I'm crocheting.

I frequently find myself wanting to think more critically and guess about things like this. If I had thought a bit further before reading (one needle, but what is the groove like?) I would gotten to assuming that it was one dimensional, but then stepped from there to it actually affording two dimensions. Does anyone have recommendations for reading or exercises to improve this kind of thinking?

  When I was a kid I used to wonder how everything worked and would disassemble things to find out. Started to take apart those disposable cameras people used to use for vacation photos. Learned the painful way what a capacitor is and how it discharges enough electricity to make that camera flash in a hurry. So my recommendation is electro-shock therapy. Self administered of course.

    Ha, excellent. I have pretty good mechanical sense & experience and can reason through how things work. I guess I just want to get better? But this applies to thinking that gets you into a rut working on a bug. Sometimes es I find that if I would have stopped, backed up, and thought through the whole stack more critically, I would have gotten the fix faster.
