Stagioni

Seasons order the course of nature to a natural calendar. Many scientific disciplines deal with the beginning, duration and shifting of seasons. Scientists also call this field of research phenology. Precise knowledge of causes and consequences is important in agriculture, weather and climate research, ecology, medicine and tourism.

Immer wieder —

Der Winter ging, der Sommer kam. Er bringt aufs neue wieder
Den vielbeliebten Wunderkram der Blumen und der Lieder.

Wie das so wechselt Jahr um Jahr, betracht ich fast mit Sorgen.
Was lebte, starb, was ist, es war, und heute wird zu morgen.

Stets muss die Bildnerin Natur den alten Ton benützen
In Haus und Garten, Wald und Flur zu ihren neuen Skizzen.

Wilhelm Busch (1832-1908)
