About this video

An excellent video by Veritasium that explains how vacuum tubes a.k.a. "thermionic valves" came to be and how they work.
If you like tech/sciency stuff, I suggest u follow their channel - Their vids are very well made and always interesting.

    Oh yeah, Veritasium is really good.

    Also Fermilab, narrated by a friend of mine.
