Way back in the dim and dark days of the 1970's when I was being taught electronics, we were tutored on a device called an Ignatron, which was a mercury vapour rectifier for turning AC power into DC, and dating back to the 1930's (yes, our education was a way off 'cutting edge' technology)! Our lecturer was an old chap, who I distinctly remember saying something like "I'm obliged to teach you this, BUT I've never even seen one outside of a textbook in my long career before taking up lecturing, let alone in use, and you lot are certainly unlikely to ever need to know this outside of an exam, but that's the curriculum for you!"
Well, he was right, never encountered one for 45 years after my 'education', UNTIL I visited a water pumping station living museum, with steam engines and ancillary equipment dating back to the early part of 20th century, and low and behold there was a working Ignatron in the flesh no less! Only a daft old engineer could get excited by such things, but it was like discovering a Unicorn, it wasn't just ancient myth and legend and tales told in dusty books, they really did exist, a sad old man's moment of elation at coming 'face to electrode' with a mythical beast!
The other sad old engineers out there will recognise the 'joy' of encountering something of the ilk, the rest of you will write me off as being a bit barmy, but all the best engineers are a bit barmy! ... I think!
Anyway my years of expensive adult education in dusty corridors of academia being taught pointless trivia wasn't all wasted, I can recognise obscure ancient artifacts in museums without need to refer to explanatory plaques or listen to guidance from curators!
