How long did it take Patriarch Photius of Constantinople to go through all the degrees that separated the layman from the head of the clergy?

In 858, the Byzantine Emperor Michael III (842-867) deposed Patriarch Ignatius and installed Photius, a scholar and courtier, in his place. Not having any, even the lowest spiritual dignity, Photius in 5 days passed all the degrees that separated the layman from the head of the clergy, and was elected the new patriarch.

Why did Dirac want to refuse the Nobel Prize?

When the English physicist Paul Dirac was awarded the Nobel Prize in 1933, he wanted to refuse it because he hated advertising. However, Rutherford still persuaded a colleague to receive an award, since the refusal would have become even more advertising.

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 ... >>

GPS signal will measure wind speed over water 02.08.2013

Winds over oceans and lakes can be tracked by reflecting GPS signals. This will help meteorologists more accurately predict the weather and, in particular, catastrophic events such as tornadoes. On a global scale, NASA experts hope to better understand our planet's climate with a new method of measuring wind speeds.

Accurate weather prediction and climate modeling requires accurate knowledge of wind strength at various altitudes, or at least near the surface. On land, this task is more or less performed by simple weather stations, but over the oceans, over the "kitchen" of the world climate, it is more difficult to make measurements. Usually, disposable probes dropped from aircraft are used for this. However, these probes are not cheap: $750 each, and in fact, during a typical mission, a "hurricane hunter" consumes about 20 of these probes.

It is clear that to obtain a pattern of winds over a large area, dropped probes are not enough. To solve this problem, NASA has developed monitoring technology that measures wind speed by bouncing GPS satellite signals off sea waves. The accuracy of such a measurement is 10 times lower than that of drop probes, which are only 0,5 m/s wrong. At the same time, analysis of the reflection of GPS signals from waves makes it possible to monitor vast areas in real time, which is very important for forecasting hurricanes.

Thanks to GPS, you can now follow the winds without dropping sensors. Wind data can be collected from aircraft and satellites. Specifically, in 2016, NASA plans to launch a system of small satellites called CYGNSS that will measure GPS returns from low orbit. This will allow forecasting the movement of storm fronts. In the future, in addition to GPS signals, it will be possible to use TV broadcast signals from powerful satellite transmitters such as DirecTV and Sirius XM for monitoring.

Thus, extremely powerful satellites provide scientists with "free" monitoring of the oceans, which until now has been an extremely difficult task. All you need is a GPS receiver, some chips and some software. All this costs several hundred dollars.
