Science: Strange weather: Instances and causes of fish falls during rain storms

Strange weather: Instances and causes of fish falls during rain storms #1

Raining animals is a rare meteorological phenomenon in which flightless animals fall from the sky – that happens no matter the sky is clear (no strong winds, tornados or waterspouts) or it was raining. Such occurrences have been reported in many countries all over the globe in human history, in many cultures: from the Roman empire to Asia, both America and Africa… from ancient times to modern days. The phenomenon is present in literature and popular culture, for example the English language has the famous words “it’s raining with cats and dogs”, but similar examples can be found in many languages over the world.

The most common animals fallen from the sky are the frogs and the fishes, but there have been seen rains of toads, snakes and worms.

One hypothesis explain the phenomenon using the strong winds that travel over the water and pick up creatures as fishes and fogs or small other animals like snakes and worms while passing over the land. These winds would carry them several kilometers and drop them when they lose their strength… but this phenomenon has never been scientifically tested or witnessed. French physicist André-Marie Ampère was among the first scientists to take seriously accounts of raining animals – one of the versions of this hypothesis was explained by the physicist to the Society of Natural Science.

Science: Myths and facts about the olive tree

Myths and facts about the olive tree #1

Facts about the olive tree

The olive tree (Olea europaea; Heb. zayith, Gk, elaia) is an evergreen tree usually about 5 meters (about 16 ft) high when pruned, but it can get much taller when unpruned. Young trees have a smooth silver grey bark, but with age the slender trunks become fluted, knobby and stout. Many old trees develop holes in the sides of the trunks which themselves are hollow; the holes result from old side branches rotting away. Besides the great olives, the numerous branches form a dense and shady tree that shelters a lot of animals in the heat of the day.

Olive leaves are narrow and sharply pointed, grey-green on the upper surface and white on the underside owing to a complete covering of minute white scales – that helps to keep down water loss from the tree. Flowers open on May, they bud develop among the leaves on the previous year’s wood. There are between 10 and 40 flowers carried on each short inflorescence, the white flowers are divided in 4 parts but they have only two stamens. The young olive trees start flowering when they are at leas 5 or 6 years old, their best olive production is between 40 and 50 years, but it is said there are a lot ancient trees that bear regular crops.
