While we wouldn’t want to document a computer motherboard with ASCII schematics, it’s great for a quick-and-dirty circuit diagrams. Not exactly schematics, but [Duckman] has some Arduino ...

Stem and leaf diagrams make it easier to read lists of number Stem and leaf diagrams are formed by splitting the number into two parts, the ‘stem’ and the ‘leaf. For example: In the number ...

The emergence of life on our planet added a new layer to the carbon cycle. As plants grow, they take CO 2 out of the atmosphere, and when they die, it is released again. Animals that consume the ...
