I am always wondering why it is called JK flip-flop?
As we know, SR flip-flop, S stands for "Set" and R stands for "Reset".
J stands for what?
and how about K?

Salam,
J and K have no significance except that they are adjacent letters in the alphabet.
Bye

Actually, the choice of the letters "JK" in the JK flip flop do have significance. The JK flip flop was named after Jack Kilby, the Texas Instruments engineer that invented the integrated circuit in 1958. The modified RS circuit that eliminated race conditions was named JK in his honor.
Search for "JK" and "Jack Kilby" simultaneously to see multiple sources for this.

Q is comes from Latin language "quiscens" or "the present particle" or "what is present available" or "present output". Similar is the word quiescence. A lot of words in physics come from Latin and Greek languages. To scientists and scholars it is an obsession. Nothing else. Just humans. You love rock and roll they love other things.
JK are intials for Jack Kilby. He shared the Nobel Prize in 2000 with a German and a Russian. To my opinion each one of them deserved a Nobel Prize separately.

No proved evidences for what you are saying, so they mean not believable.
That's why in general I never care about the component's and circuit's names, I just learn their names by heart and care only about its functions, parameters and how to use it well and how to distinguish it from the other similar components/circuits.
