Reference Desk favorites edit
I mainly read and contribute to the Reference Desk. Here are some favorites I've selected:
Interesting questions
- Tuning before the study of frequency -- How could you specify an absolute pitch before the concept of frequencies in hertz was available?
- How has this image been generated? -- How is an image illustrating CGA composite artifacts generated in modern software? It involves constructing then decoding an NTSC signal, but I don't understand all of the the math involved.
