world sorrow
(О чьем-либо мрачном виде, плохом настроении, унынии и т. п. (шутл.-ирон.))
From German: Weltschmerz. From the unfinished work "Selina, or on Immortality" (published 1827) by the German satirist Jean Paul (pseudonym J.-P. Richter, 1763-1825), who used this expression, speaking of "the countless torments of people." As the Russian poet and translator Pyotr Isaevich Weinberg (1830-1908) wrote in his article "The Poetry of World Sorrow" (1895), world sorrow is "sorrow for the imperfections of the world, for the disorder in it and for the suffering of mankind." The expression became especially popular after the publication of the article "From the exhibition of paintings in 1831." the German poet Heinrich Heine, who, speaking of the painting by the artist Delaroche "Oliver Cromwell at the body of Charles I", wrote: "What great world grief the master expressed in a few lines!"

Random fact "Did you know?":

Немецкие генетики пересадили ген производства паутины от паука картошке. В результате до 2% белков, производимых растением, составляет белок паутины. Его легко выделить из картофеля, так как он растворяется в воде. Теперь инженерам надо научиться прясть из этого белка такую же тонкую, но прочную нить, какая получается у пауков, и тогда можно будет делать легкие сверхпрочные ткани.

Random article of the Great Encyclopedia for Children and Adults:

Why are whales considered mammals?

If a whale lives in the water and is similar in shape to a fish, then why is it not considered a fish? But because a whale is a marine mammal that comes from earthly ancestors. For many millennia spent in the water, the whales began to resemble fish in shape, but in the structure of the body and way of life they remained similar to land animals.

For example, whale fins have an internal structure that resembles a hand with five fingers. On the body of some whales there are even bones in place of the hind legs! But the most important difference between whales and fish is that, like all other mammals, whales feed their young with mother's milk. These cubs do not hatch from eggs or caviar, but are born alive. And for some time after birth, the kitten remains next to its mother, who takes care of it.

Since all mammals are warm-blooded, and the whale does not have fur to keep it warm in icy water, instead it has blubber, which is a layer of subcutaneous tissue filled with fat and retains heat like a fur coat. And whales breathe differently than fish. Instead of gills, they have lungs into which they take in air through two nostrils located at the top of their heads.

When whales dive underwater, these nostrils close with small flaps to keep water out. Every five to ten minutes the whale rises to the surface of the water to take a breath. First of all, it noisily spews out exhaust air through the nostrils. As a result of this, the same "fountain" appears, which is always drawn in pictures about whales. Then he draws fresh air into his lungs and dives again to continue moving under water.
