[Elecraft] A little theory

[Fred Jensen]

A short story, possibly apocryphal ["alternative fact" in today's 
vernacular], that circulated at NASA during Apollo, had Dr. Feynman 
lecturing on some subject.  At one point, the chalk hit the blackboard, 
he wrote out an equation [or something like that] and then said, "This 
is obvious, of course."  He paused, turned and left the room, leaving 
everyone wondering if that was all.  A couple of minutes later, he was 
said to return and continue the lecture with, "Yes, it is definitely 
obvious."

I don't know if it's true but it sure fits his style.

And a sound that is precious (in retrospect) to me  -  the sound of chalk hitting blackboard.   That “leading edge”, the audible signal that something important may follow, is an “attention getter” that physicists and mathematicians will always be attuned to.   It can be heard about 2 minutes into your clip.
