Where and when were video record players sold?

Records served not only to transmit sound information. In the 1970s, the German firms Telefunken and Teldec introduced a special foil video player to the market.

The disk in the device rotated at a speed of 1500 revolutions per minute and could hold no more than 10 minutes of video. But such a system was not widely used due to the beginning of the VHS era.

Why do baby kangaroos stay in a pouch for so long?

Marsupials form a special type of mammals. They differ from other mammals in the way they bear and care for their young. At birth, a baby kangaroo is barely 2,5 cm long and is not even fully formed. The tail and hind legs of baby kangaroos resemble small stumps. The eyes are closed and the ears are not shaped. The mouth of the cubs is just a hole. Only the front paws are well developed, with fingers and claws.

Barely born, the baby kangaroo begins to wade through the mother's fur to the hole in the bag on her belly. They are driven by instinct. Mother at this time licks the opening of the bag. Scratching with its front paws, the kangaroo still reaches the opening of the bag and looks out. Inside the bag, the newborn quickly finds the mother's nipples and begins to feed.

A small kangaroo stays in the bag for several weeks, hatches and develops there. He grows, becomes covered with wool, opens his eyes, his ears are formed. Finally, he comes off the nipples and jumps out of the bag. The cub leaves the bag at the age of several months, but if he is in danger at this time, he can immediately climb back into it. But by the age of six months, it reaches such a size that it does not fit in a bag. The kangaroo begins to eat grass, vegetables, like the mother. He is already strong enough to take care of himself.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Mars laser catapult 23.02.2022

In Canada, they proposed sending astronauts to Mars with a laser "catapult". Local scientists believe that with the help of a revolutionary idea, they can reduce travel time to 45 days.

This is many times greater than the performance that existing technologies are capable of - the NASA Perseverance rover traveled to the Red Planet in just over 7 months.

The idea is to build a laser-thermal propulsion system on Earth from a group of infrared lasers with a diameter of ten meters and a power of 100 megawatts. Approximately 80 American households consume this much.

An orbiting craft would have a reflector that would aim beams from the planet's surface into a heating chamber filled with hydrogen plasma. As the temperature rises, it will be ejected through the nozzle, thus creating powerful thrust. As planned, when the radiation subsides, the ship will accelerate to 17 km / s.

However, this is also the main snag - the researchers still have little idea how to slow down at the destination. This may require a similar laser facility on the Red Planet to create reverse thrust. However, in this case, you need to wait until people master Mars.

Flights with the help of a laser catapult can start no earlier than 2040, but for now the first colonists will have to get to Mars on conventional rockets. SpaceX Muska has calculated that it will take them about six months to fly on conventional fuel.
