Pitch is a precept, measurable only by psychophysical investigation, and frequency is a physical quality that describes the periodic properties of signal. Sounds that contain physically measurable signal content may not produce a clear or unambiguous sense of pitch, and the perceived pitch may depend on other physical qualities such as intensity.
— Oxford Handbook of Music Psychology
In other words, the listener's brain constructs musical pitch; it's partly subjective.

"Le soleil, qui a peut-être créé la vie, quand sa lumière était plus riche en rayons chimiques"
Allons bon.
Quoi c'est-y donc qu'un rayon chimique ?
(Edmond Perrier, La Vie en action, Flammarion, 1918, p. 156-157).
Update : c'est l'ancien nom des ultraviolets ! #TIL
"Prenant connaissance de la découverte des rayons calorifiques par William Herschel en 1800, Johann Wilhelm Ritter décide d'investiguer l'autre extrémité du spectre. Il constate en 1801 que le chlorure d'argent, substance connue pour noircir en présence de lumière d'autant plus fortement que l'on se rapproche du bleu, continue de noircir au-delà du spectre visible, ce qui marque l'existence de rayonnement au-delà du bleu."
https://fr.wikipedia.org/wiki/Rayons_chimiques
"Il qualifia ce rayonnement invisible de « rayons oxydants », à la fois pour montrer leur réactivité chimique et les opposer aux « rayons thermiques » (c'est-à-dire infrarouges), (...) On adopta peu après l'expression plus simple de « rayons chimiques », qui demeura en usage jusqu'à la fin du XIXe siècle, en dépit des allégations de chercheurs qui y voyaient un rayonnement d'origine essentiellement non-lumineuse (notamment John William Draper, qui les baptisait pour cette raison « rayons tithoniques ») ; mais finalement les termes de « rayons chimiques » et de « rayons thermiques » le cédèrent aux termes de rayonnement « ultraviolet » et infrarouge, respectivement."

I remember reading about how French revolutionaries tried to replace the 7-day week with 10-days in the 1790s, but I never knew the Soviets tried something similar. Both wanted to move people away from religious activity on Sundays (among other goals).
From 1929-1940, industrial workers in the USSR had staggered 5-day work cycles. Four days on, one day off, with 20% of employees off on any given day, and the factories never shutting down. It was a big increase in leisure time (1/5 instead of 1/7) but schedules didn't usually match your family or friends so the time had less value.
The experiment was brought to an end by the Nazi invasion in 1940 when they shifted back to 7 day cycles.

»„Das Jahr 2440“ spielt als erste Utopie überhaupt in der Zukunft und gilt als DIE Utopie der Aufklärung, da man nun die ideale Welt erreichen konnte, denn diese Utopie war nun nicht mehr irgendein versteckter Ort, sondern die Zukunft.«
Ein utopischer Roman von 1771, in dem es um Gleichberechtigung und die Abschaffung der Sklaverei geht. Heute in Mike Duncans Revolutions Podcast zum ersten Mal von gehört (4.02, The Web of Tension).
Today I learned, thanks to a comment on here, that the alphabetical order of your #Apache site config files is what determines the default site if somebody tries just punching your public IP address directly into a web browser. I always wondered why the default site config files were named "000-default.conf"; it's to make sure that one is always loaded first as the default if it's enabled.
