I hear a lot of seniors use the term, “jiffy.”
- “I’ll be back in a jiffy”
- “It’ll only take a jiffy”
You probably didn’t know that the term “jiffy” is actually a scientific term for time measurement. The odd thing is, the term is defined differently for different fields of science.
Originally, it was the time it took light to travel 1 centimeter (not very long). Now, in electronics, at least, it’s 1/50 or 1/60 of a second. It’s much shorter in physics.
