On July 19, 1952, Palomar Observatory was undertaking a photographic survey of the night sky. Part of the project was to take multiple images of the same region of sky, to help identify things such as asteroids. At around 8:52 that evening a photographic plate captured the light of three stars clustered together. At a magnitude of 15, they were reasonably bright in the image. At 9:45 pm the same region of sky was captured again, but this time the three stars were nowhere to be seen. In less than an hour they had completely vanished.
Didn’t realize they had pixelated photos in 1952…
If you find that interesting, the history of pixels and computer displays gles far back.
They had pen touch displays all the way back in 1946, it’s actually pretty interesting how long some of the tech that exploded in the mid 2000s has actually been around.

The public library in my town when I was a kid in the 80s replaced their card catalog with a touchscreen computer system. It barely worked, sometimes you had to press below where you were supposed to press, but the idea was cool.
That was a super interesting little dive thank you.
