Go on then, enlighten us...

oh its one of those principles, thingies, you were talking about. like once you know them you can deduce the world.
IIRC there was a problem in amplifiers and the cause was that the electrons moved through the vacuum, hit the cathode but then bounced off before being reattracted. This proved that these things had mass. i.e. its a physical bounce rather than a magnetic type one.

interesting if you do a degree in ancient electronics, otherwise, useless, totally useless.

Pretty much everything has mass when it changes direction, even massless things.

There was a small dimple in my understanding of our World that has now been filled. Thank you.

There is an object in the universe that can change direction so quickly that it can be proven to have no mass, yet the inertia is so great that it must have infinite mass.
It's called my project manager

Gosh.

Even when I was doing my first attempt at a degree, vacuum state electronics wasn't on the curriculum.

Though we did do weird things like crts using magnetic & electrostatic deflection as I recall. Electron ballistics, that's what it was called.

No one younger than about 45 has ever heard of any of it.

Also did stuff about magnetic amplifiers which are even more obscure, despite being used in 99% of PC psus.

Now people are too stupid to make the connection.

national wealth is created by borrowing money, innit?
