Did you know !!!!!!

* Iceberg contains more heat than a burning match, but this heat is evenly distributed throughout the thickness of frozen water

* King of England Charles the Second rubbed dust from Egyptian mummies to “absorb the ancient greatness”

* Caves "breathe". This occurs when atmospheric pressure changes and the air inside them exits through cracks to the outside or, with increased external pressure, seeps in.Recommended - ordering a gazelle in Moscow will help you quickly deliver any goods.

* Cases of injury by meteorites are extremely rare, but nevertheless recorded in history. For example, on June 21, 1994, Spaniard Jose Martin and his wife were driving in a car near Madrid, when a meteorite weighing one and a half kilograms flew into the windshield, bent the steering wheel and got stuck in the back seat. Martin's finger broke, his wife escaped with a slight startle.

* If someone asks you to name poisonous animals, then you will probably remember about snakes, spiders and scorpions. However, in the world there are at least three species of poisonous ... birds. One of these birds with a very dissonant name, the crested pitohui (Pitohui dichrous) lives in New Guinea. The poison is found in the skin, in feathers and in almost all internal organs. The venom of New Guinean birds is akin to batrachotoxin - the very one that literally soaks the body of Colombian poison frogs. Of course, in the flycatcher, the concentration of poison in the body is much lower than in the body of poison frogs. A bird weighing 60-65 g contains 15-20 micrograms of toxin in the skin and 2-3 micrograms in the feather. For humans, getting this poison only threatens poisoning or a severe burn, but rabbits, dogs, mice, toads and frogs die in a matter of minutes.



* When a new uterus arrives in a bee hive, it begins to “sing” at a certain frequency, prompting working bees to kill other queens, if any are in the hive. The frequency of this sound is the same for all species of bees, with the exception of African ones - these buzz louder and higher.

* There is a hypothesis that our Sun has a companion star located at a distance of one and a half light years from the star. Its orbit is elliptical, the period of revolution is about 26 million years, during a certain period this star exchanges matter with the Sun, while part of the “exchange” crosses the Earth’s orbit, which causes the mass extinction of most living things on our planet. In a number of studies, scientists managed to find such a periodicity, but there is no direct evidence for the existence of such a companion star. It is believed that this is a red dwarf, it even has a name - Nemesis.

* There is such a mineral - fulgirite, which is formed as a result of a lightning strike in the soil. At the same time, under the influence of high temperature (1500 degrees and above), sand and clay instantly melt, forming glass-like tubes. The photo shows a fragment of such a mineral.

* At the time of the invention of his temperature scale, Anders Celsius believed that zero degrees is the boiling point, and 100 degrees is the freezing point of water. After his death, the Swedish doctor Carl Linney proposed to reverse the scale, which was done.

* Occidental College, in Los Angeles, is known for its original curriculum. It is also the only educational institution in the world where there is an item called Stupidity. Led by a professor of philosophy, students learn stupidity using President Bush and the animated series Beavis and Butthead. They say that nobody exams at exams.

* If you throw three balls - rubber, glass and metal - onto a hard (for example, granite) surface, which one will bounce higher, what do you think? No, not rubber, but glass, after metal, and rubber will show the worst result. This is because the rubber ball deforms when it hits, “spreads” over the surface, so most of the kinetic energy is lost to the friction and deformation of the ball.

* The oldest parliament in the world is the parliament of Iceland. It was approved in 930 - more than a thousand years ago.

* The speed of sound propagation in metal is much higher than in air - more than 5000 meters per second. For comparison, in water this value is 1480 meters per second, and in the air even less - 330 meters per second.

* Most icebergs are made up of frozen fresh water that has broken away from the glacier. There are also “salted” icebergs that can be identified by their green color. When freshwater icebergs fall into salt water, under certain conditions, this water freezes over fresh ice, forming characteristic colored blue-green stripes. In the photo - one of such colored icebergs.

* We all live in the ice age. It began 10-15 thousand years ago, and will continue for at least 50 thousand years. After us, icing, glaciers and other interesting events await. So in your place, I would not worry about "global warming."

* In 1952, Israel proposed becoming president of Albert Einstein, but the scientist refused.

* The 27th amendment to the US Constitution was introduced in 1789, and approved in 1992, after 202 years. Everything is clear, given that in it senators are forbidden to raise their salaries before being re-elected.

* On the island of Sark near England (population up to a thousand people), feudalism was the official system until 2008.

* The first nuclear reactor was built on a squash court near the Chicago Football Stadium on December 2, 1942. The power of this reactor was barely enough for one light bulb, but nevertheless, the beginning was laid. The project was led by the famous Italian physicist Enrico Fermi.

* The American company Lewyt Corp in the 50s was developing ... a nuclear vacuum cleaner. Alex Levitic was so sure of success that he claimed that by 1965 these devices would appear in stores.
