Pandorum Stage II

[Sumpter250]

I could go into a dissertation on how a Magnetron actually produces microwaves, or describe how a Waveguide Duplexer works, or draw the full schematic of a full adder ( computer circuit), and describe, one clock pulse at a time, how it adds, subtracts, multiplies, and divides, uses the carry register, the input registers, and the output register.
There may be one or two who would be able to "understand".
But, but, I know it, therefore everyone should know it !! NOT.
It is called " Common Knowledge Syndrome", and it is the root of most misunderstandings. It was one of the hardest lessons I had to learn, before I could begin to be a good instructor.
I am sure that if I were to use the term "Flemish Horse", Someone, somewhere, would want to know what the odds were that it would win.
Wikipedia defines it: A flemish horse is a footrope on a square rigged sailing ship that is found at the extreme outer end of the yard.
Unless I knew that someone was a ship modeler, or maritime historian, I would not expect them to "understand" what a Flemish Horse was, but it is as much a part of my "professional language", as "Good morning" is a part of my "everyday language".
Let's all try to remember, "Common knowledge", isn't as "common" as we might think it is.
