I have sometimes surprised people because I can recall and explain de Morgan's Law that
not (A and B) = (not A) or (not B)
and
not (A or B) = (not A) and (not B)
I remember it because I find it elegant.
Clever chap, that de Morgan. He also wrote one of my favourite poems (of which I was reminded by yours):
Little fleas have littler fleas Upon their backs to bite 'em. And littler fleas have still littler fleas And so on, ad infinitum.
But
I see that with my usual incompetence of memory for quotes, I do not
recall it correctly: https://en.wikipedia.org/wiki/Siphonaptera_(poem)
. And now that I see it is a parody of a satire about poets, I am even more
impressed with the genius of de Morgan.
And I think I'm doing well just because I can remember one of his laws of logic.
I feel if I tried to hold a candle to the likes of de Morgan and Swift, I would burn my fingers with hot wax, wreck the carpet, then find I had arrived a week early.
Or - crushingly - two or three centuries too late.
Who are the Jonathan Swifts of today? Are there any?

Fourth attempt at that link: en.wikipedia.org/wiki/Siphonaptera_(poem)

I always remembered
Big fleas have little fleas upon their backs to bite 'em,
And little fleas have lesser fleas, and so, ad infinitum.
which I thought was by Swift, but I see I was wrong and it is De Morgan's version.
I liked the others on the WP page as well, very good!
