I mentioned previously a friend of mine on fb who is quite a photographer himself, and the husband of UHH member Judy 2011, worked on adding a component to the SR71. He posted a photo of a large group of people in front of the plane and I could pick him out basically because he's tall. This was at Edwards AFB. He was in the AF at the time. He also had to get into the cockpit of the beast while they were working on it to install the component. He DID say they had to be very careful not to drop a pin or anything. No pictures of him sitting in the cockpit. No allowed. You know what happened to that sailor that took snapshots of his submarine!!

"We" being whom?
You must be a quantum physicist? This type of notation is a bit "beyond" Laymen, like me.
Perhaps you could define Micro & Nano in metaphorical terms, yes?

I think it was covered in 6th grade math; but as a refresher here you are, on the math is fun website:

Thanks for your condescending answer. I was in the 6th grade in 1947, and that wasn't covered. We barely learned the multiplication tables past 10.
That was shortly after those two nuclear fission experiments in Japan. Maybe, you're too young to remember that?

No condescension meant, just answering in the tone you used in the question.
But really I have to believe scientific notation was a part of math classes in either primary or high school, even in the 1940s and early 1950s.
Not being a science major, I was not familiar with the term "SCIENTIFIC NOTATION". So, I looked it up:
SCIENTIFIC NOTATION is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9.
I stated that I was (am) a layman. Had you given the example about exponential progression, and explained that MICRO (10 to minus 6th power) indicated 1/1,000,000; and, that NANO (10 to the minus 9th power) was even smaller I would have understood.
Now I know, but with no thanks to you.

Actually had you looked at the URL I attached to my post above you would have found all that out, and more. So its not my fault if you didn't use the support documentation I provided.

Fault? I said nothing about Fault.
It was just easier for you to paste an URL in your reply than taking a brief moment to post a simple explanation.
And, instead of reading that URL you posted, I found it easier to Google the specific information I wanted.
So, because of your ostensible intellectual capabilities, please give me (us) a brief synopsis of everything you know something about - and, without URL's. Go ahead, I've got a couple minutes; probably won't take even that long.

I believe I already did in the first thing I said about scientific notation. This is my post from page 3 of this thread.
"That's why we work in scientific notation.
Micro = #*10^-6
Nano = #*10^-9
Pico = #*10^-12
Part of the norm for electrical engineering with or without slide rules."
It's when you ignored that post that I put up the URL.
And with that, this is the last I have to say on this subject.
