Found the perfect ending for my block on binary and hex codes: The plates carried by the space probes Pioneer and Voyager!
They use a fundamental measurement of hydrogen amounting to 0.7 nanoseconds and binary code to try to communicate with aliens. Here's an example:
If you jot down the binary number around the disc, it's 100110000110010000000000000000000. In decimal numbers, that's 5'113'380'864.
If you multiply that with the fundamental measurement of hydrogen (0.7 nanoseconds), you get ~3.6 seconds, which is how long one rotation of the disc should take to hear the sounds properly.
Besides this, it was apparently also upon Carl Sagan's initiative, to turn Voyager 1 around and shoot that picture where earth is just a "pale blue dot".... His take is very moving 🥹
