Most anyone would have just broke down and changed jobs.
Ah, the man I want. Tell me, is "Ijon Tichy" a joke on "tachyon", or something else?
(noticed that years ago, been wondering it could not possibly be accidental, not Lem ...)
The word 'tichy' means 'silent' in Czech/Slovakian, and maybe in some smaller Polish dialects.
Though http://encyklopediafantastyki.pl/index.php?title=Ijon_Tichy claims that "the ancestor of Tichy was called Cichy (the silent one in Polish), but the official putting down the name in the official register was lisping"
