Why are kindergartens called that?

In 1837, the German teacher Friedrich Fröbel opened an educational institution for young children, where they could play, sing, dance and learn important life skills, calling it Kindergarten, which means "kindergarten". Through this concept, Fröbel wanted to draw an analogy between such institutions and familiar gardens: children should be cared for and looked after in the same way as plants are looked after. Today, preschools are called kindergartens in many languages of the world.

How long do animals live?

Long-lived species are found at different stages of the evolutionary development of animals.

Of multicellular animals, sponges live up to 10-15 years, coelenterates in some cases up to 70-80 years (anemones), representatives of various groups of worms from 1-3 to several decades, spiders 4-5, sometimes up to 20 years (female tarantulas) , crustaceans - from a few weeks (daphnia) to 50 years (lobsters).

Insects in the imago stage (characterized by the full development of wings and the presence of sexual appendages at the end of the abdomen) usually do not live long, but some are homoptera up to 40-60 years.

The life expectancy of laminabranch mollusks is up to 100 years, however, many species of mollusks live for several months or even weeks.

From vertebrates: sturgeons live up to 50-100 years, giant salamander - over 50 years, toads and newts - up to 25-30 years, frogs - up to 12-13 years, crocodiles and turtles live up to 50-150 years.

From birds: eagle owls, crows, golden eagles, white pelican, parrots live up to 50-70 years, gulls, cranes, condor, African ostrich - up to 30-40 years.

Some mammals - up to 70-110 years. The maximum life expectancy within a class usually differs by several dozen times, and within a detachment by several times. So, in mammals, small rodents (mice, rats) live up to 3-4 years, predators (cat, leopard, lion, dog, wolf) - up to 25-30 years, artiodactyls (pig, sheep, cow, deer, elk) - up to 15-30 years, equine (donkey, zebra, horse, elephant) - up to 30-70 years, monkeys (orangutans, chimpanzees) - up to 25-45 years. The record holder for longevity among mammals is the bowhead whale, whose life expectancy can reach 150 years.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Security on the Internet 12.12.2001

A small electronic company "Scholey" in Wales (Great Britain) has developed a system of television surveillance via the Internet. It is five times cheaper than conventional surveillance systems, in which cameras placed on the streets or inside guarded buildings are connected by cable to monitors in the security room.

Cheapness is explained by the fact that there is no need to lay cables (you can view the image via the Internet by phone) and pay for three shifts of on-duty observers (the camera has a memory). Actually, there are few places in the world that it is desirable to watch inseparably every minute 24 hours a day. You can simply view the frames stored in the camera from time to time.

The Sholi TV camera is connected to the Internet and is equipped with a hard disk for recording images. In the more expensive model, the recording is on DVD, with one disc containing footage from a network of eight cameras in a month of operation. The picture received in real time or recorded can be viewed via the Internet. Distance doesn't matter. For example, being in a Hong Kong cafe, you can see what is happening in your apartment on the other side of the Earth, if you have a laptop or PDA and a cell phone with you. The image quality allows people to be identified and used as evidence in court.

The camera can be remotely controlled, also via the Internet - rotate, tilt, change the focal length of the lens. The transmitted image is encoded so that not every Internet user can look where he is not supposed to. In addition, to view the image, you need to know the phone number with which the camera is associated.
