This is the entry for 'poika' in a Finnish etymological dictionary (Nykysuomen etymologinen sanakirja), run through deepl:
"The word has definite etymological equivalents in both closely related and distantly related languages, e.g. Karelian and Votic poika, Ludic and Vepsian poig}, Estonian poeg, Livonian puoga, Komi and Udmurt pi, Mansi pig, and Hungarian fiu. Possible equivalents are also the initial parts of the Mordvin word pijo 'grandchild' and the Mari word puerge 'male person' (erge 'man'). The original form of the word has been reconstructed as *pojka. The Swedish pojke, which in the past also meant 'servant boy', is apparently a loanword from Finnish. In contrast, the English boy and the etymologically related German Bube have different origins."
There are actually two distinct languages (a kind of Proto-Proto-Proto-Indo-European and Proto-Proto-Proto-Uralic) spoken in the movie, created by Anthony Burgess. He later wrote an essay (the title of which escapes me ATM) about the thinking behind it.
There is an effect called dispersion, which causes different frequencies of electromagnetic radiation to travel through a medium at different speeds (lower frequencies => slower).
It's strong enough to be noticeable in the case of pulsars (but probably insignificant inside the solar system).
Quote:
'The first part of tragedy in Kazakh language was published in 1969. The full translation of Goethe’s drama poem "Faust" was edited in 1983. The translation of "Faust" into Kazakh language in Germany was marked. Klaus Schneider in his book «Alma-Ata. Kasachischer Fruehling» writes with delight about Medeubai Kurmanov. Many warm words are written about him in the reporting of Rut Kraft «Fruechte aus Alma-Ata». Medeubai Kurmanov is selected the honorary member of Goethe International society.'
Pareto made a distinction between 'residues' (psychological bases underlying social action) and 'derivations' (rationalizations by members of society as justifications of those actions). It might be used in that sense here.
