Why are Rapid Vienna fans applauding for the last 15 minutes of every match?

In 1939, the Viennese club "Rapid" met in the final match of the championship of the united Germany with "Frankfurt" and scored the decisive three goals in the last 15 minutes. Since then, a tradition has been established at Rapid's home matches - the last 15 minutes of the match are rhythmically and continuously applauded by the fans.

How does silkworm spin silk?

Thousands of years ago, the Chinese learned the secret of making silk clothes from a beautiful linen spun by a special caterpillar in the manufacture of a cocoon. This secret was kept in the strictest confidence, and if someone exported a silkworm or its eggs from China, then he was sentenced to death.

Now, of course, silkworms are common not only in China, but also in Japan, India, France, Spain, Italy and many other countries. The best silk is produced by a caterpillar of a small greyish-white moth that feeds on white mulberry leaves.

In early summer, each female lays 500 or more eggs. They are perfectly preserved on a piece of paper or clothing until the next spring, when the mulberry leaves begin to bloom again. Tiny black worms emerge from the eggs placed in the incubator. They are placed on a tray with plucked mulberry leaves, and they constantly feed on them for six weeks.

When the worms begin to barely turn their heads, this indicates that they are ready to weave their cocoon. They put small branches on a tray. Worms twine themselves with an almost invisible thread that extends from a small opening in their jaws. The cocoon, which consists of 460-1100 meters of thread, is finally ready in about 72 hours.

Inside the cocoon is a shriveled caterpillar, which turns into a moth after 12 days. The cocoons are placed in troughs with warm water, which dissolves the silk glue that holds all the threads in a certain shape.

Threads from several cocoons are connected together into one thread, which is wound into a spool. Then comes the next stage - twisting raw silk into yarn. This thread, consisting of 10-12 fibers of individual cocoons, is called a single silk thread.

When we buy things made of silk, they are marked with what kind of thread they are made of - double or triple. In our time, nylon has become so popular and cheap that it has begun to replace silk. But still, silk will always be valued for its beauty, good quality and softness.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

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 ... >>

New type of wireless charging from Microsoft 21.01.2015

Microsoft's research division has developed wireless smartphone charging technology that allows you to place your smartphone anywhere and without putting it on a special stand. The new technology consists of two parts: a light-beam charging system and a mobile device detection system on the table.

“The new method eliminates the need to connect a cable to the smartphone or place the device on the charger stand. For AutoCharge to work, the device simply needs to be placed on the table. The installation itself will find the location of the smartphone and direct a beam of light at it if the battery level is low,” the engineers explain. We created a prototype installation and tested it"

For energy transfer, the same method is used that is used in solar panels. When light hits a solar panel, an electric current is generated in its circuit. In order to make the transfer of energy with the help of light indoors efficient, the engineers made the beam concentrated and strictly directed. The light source is LEDs.

A video camera is used to detect the smartphone on the table. She takes off the entire surface of the table. As soon as a device appears on it, the installation controller, using an electric drive, turns the light emitter towards the mobile phone. Smartphone detection takes about 30ms, and the beam appears after a second. As soon as the battery of the device is fully charged, the beam turns off. If there are several devices on the table, the unit can charge them all one by one.

For the technology to work, it is necessary to equip the device being charged with a photocell, which will convert light into electric current. To know the charge level, use the light indicator on the mobile device. He also informs the system that the battery is fully charged and the beam must be turned off. If a foreign object gets in the way of the light, the system can interrupt the light emission within 50 ms.

Microsoft Research specialists note that both the back and front panels of the smartphone can be equipped with photocells, so it will not matter how it lies on the table.
