It starts with electrons and Silicon. The silicon is doped with Boron (P-Type) or Antimony (N-Type) to change its type or charge. Joing the two in a PN junction allows connecting electricity in a single direction: it's a diode. If we do more junctions, we can to an NPN transistor construction, which is in fact a electric switch.

It allows us to do boolean algebra with two values: true and false, 0 and 1, or at the physical level high and low. We can arrange transistors to make circuits that behave like boolean operations: OR, AND, NOT, NAND, etc. With the magic of math, we know that we can express all other boolean operations with just NAND. #RustInParis
