Zoom Into a Microchip
It is absolutely crazy how tiny we can make things today.
What we’re seeing here is a standard microchip, older though in principle the same as modern cell phone chip.
At the micro level we’re dealing with this comparison:
"A micron is 1 millionth of a meter, 10-6 or 10-3 of a millimeter. Very tiny. It is abbreviated with the greek letter for M, or the mu."
It takes 100,000 Microns to equal about 4 inches and toward the end of the set we’re in the 1 micron range.
