I suppose a good demo would be a pulsing laser bouncing off a mirror and then hitting a detector, to explain how LIDAR works by observing the delay as the distance to the mirror is changed. Could also do something similar with a speaker and microphone, to show the difference in speed of sound vs speed of light.

I was thinking of Olympic touch pads and time resolution and the "key debounce problem". I would show a capture of  typical unfiltered raw button press and then explain that everytime they are typing on a computer keyboard multiple edges are occurring and that the micro in the keyboard is filtering those out. The same happens for aquatic sports touch pads, increasing the possibility of a tie being recorded.

That reminds me: in the 'German Sport and Olympics Museum' (in Cologne), to explain how close this race was, there are two buttons next to each other. You task is to press them, one after the other, and get a time difference of just 1/100th of a second between the presses. (I think I came down to 6 or 7 hundredths of a second, but not better)

Then you must show them what 1ns is, vs 1 microsecond, this style:



Good programmers will already be aware of visual representations of time scales from other places similar with this:

but I think the physical piece of a "1ns wire", vs a spool of "1us wire", has more impact than any chart.  You can pass them the wires, so they can touch and feel their weight while passing the two from one to another.

If the time difference between two runners is under 50ms, then it's as good as a draw.

I had a stopwatch with a resolution of 0.01s as a child. If I pressed the start/stop button twice very quickly, I could get it to stop at 0.03s. I thought it was pointless having such a high resolution. 0.1s, would have been more than good enough. The extra digit made no difference, given the human is the weakest link.

I'm certain that if I were giving the talk (on oscilloscopes) I would share the entire Grace Hopper video, just because everyone should know who Grace Hopper was and get a chance to see her.
