Where are marathons in which people compete at the same time as horses?

Since 1980, Wales has hosted an annual 35 km cross-country marathon in which people compete at the same time as jockeys on horseback. It was invented by the owner of a local bar, who heard the words of one of the visitors that at a long distance a man will not yield to a horse.

At first, people were far behind, and in 1985 cyclists were allowed to participate, one of whom won the victory four years later. Then the cyclists were again refused, and only in 2004 a runner named Hugh Lobb managed to overtake all the horses, and three years later Florian Halzinger repeated his success.

Similar marathons are also held in Scotland and New Zealand.

Why did the Vikings cut and burn the nails of the dead?

According to Scandinavian mythology, in Ragnarok, an army of etuns will sail to battle with the aesir gods on the Naglfar, a ship made of the nails of the dead. Therefore, the Vikings had a custom to cut and burn the nails of the dead in order to prevent the creation of Naglfar.

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 ... >>

Light radar on a microchip 12.01.2013

Engineers from the Massachusetts Institute of Technology have created on a microchip an analogue of a phased array antenna, which allows you to direct light in the right direction and has the potential to create a holographic image.

The principle of operation of the device resembles modern military radars. In them, instead of a single moving source of radio pulses, a fixed array (matrix) of many individual emitters is used. The phase of the wave in these radiators is strictly controlled. Due to the interference of waves between adjacent emitters, it is possible to create a beam that is narrowly directed in a certain direction. By changing the phases in individual emitters, this beam can be made to "run" along the horizon at a speed unattainable for ordinary heavy radars.

Engineers reproduced the principle of operation of a phased antenna array on two silicon microchips. Both versions of the device are arrayed antennas connected by silicon waveguides, which receive light from an external source - a laser.

In the first, static version, there were 4096 antennas on the substrate in rows of 64 by 64. Getting on the microchip, the light from the laser propagates through the device and forms a static image with the help of interference - the logo of the MIT Institute. In the second, dynamic version, there were fewer antennas - 8 by 8 rows, but they could change their phase, due to which the resulting image moved.

The existing technology does not limit the size of the antenna array, which could potentially be very large, the engineers said. This means that such a device can become a source of holographic radiation, which can be used in engineering, medicine, or to create holographic displays.
