The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.

Isochrones

isolines of the simultaneity of a particular phenomenon.

In meteorology, isochrones of various meteorological elements are examined (for example, a perennial average transition of air temperature through 0°C). In astronomy, isochrones of solar eclipses are constructed corresponding to the beginning or end of a partial eclipse or to the greatest phase. Isochrones of the beginning and end of a partial eclipse are contours of the lunar penumbra that graphically indicate its progress along the surface of the earth.

Here, Nietzsche develops the pseudo-scientific rationale of cultural isochrones, by means of which he tries to establish that the Ubermensch is not a matter of historical progress, but of surpassing oneself in a way that serves as a measure of and justifies the entire cultural context: "Wenn es einmal moglich sein wird, isochronische Cultur-Linien durch die Gesehichte zu ziehen, so wird der moderne Begriff Fortschritt artig auf den Kopf zu stehen kommen" (KSA 13: 191).
