 Random interesting fact from the Great Encyclopedia:

What did the philosopher Auguste Comte consider the most striking example of such knowledge, which will forever remain hidden from man, and why was he wrong?

In 1844, the philosopher Auguste Comte (1798-1857) was looking for an example of such knowledge that would forever remain hidden from mankind. He focused on the chemical composition of distant stars and planets. Comte believed that a person would never visit them and, having no samples of a substance in his hands, was forever deprived of the opportunity to know its composition.

Auguste Comte chose an extremely unfortunate example. Just three years after his death, it became clear that the spectrum of their radiation could be used to determine the chemical composition of distant objects.

Astronomical spectroscopy made it possible to determine the composition of the gas shells of the planets of the solar system, the chemical composition of the Sun, distant stars and galaxies.

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 ... >>

Martian soil will be delivered to Earth 25.04.2018

Currently, soil and sand from the surface of Mars can only be explored remotely: this is done, for example, by the Curiosity rover. The device collects samples of dry soil, sorts particles by size and analyzes their chemical composition using built-in scientific instruments. However, a much more accurate analysis is available on Earth - its methods are constantly being improved.

Representatives of NASA and the European Space Agency (ESA) have developed a plan to bring soil samples to Earth from the surface of Mars.

The plan for delivering soil to Earth was divided into three main stages. The first will be the launch of the Mars 2020 rover, which began to be assembled in April 2018. About 30 containers for soil were included in the design of the apparatus, each the size of a ballpoint pen. On the next mission to Mars, a small rover will arrive to pick up the sample containers and deliver them to the Mars Ascent Vehicle rocket. It will put the cargo into Martian orbit, from where another spacecraft launched from Earth will pick up the sample containers and other collected materials. The ship responsible for the last leg is expected to land in the US.

During the same period, the apparatus of the joint Russian-European mission ExoMars will operate on the Red Planet. The drill of this device will be able to extract samples from a depth of about two meters. His work will allow researchers to choose which Martian soil samples to bring back to Earth.

Detailed planning results for the new series of missions will be presented at the 2019 ESA Council of Ministers meeting. If they approve the results, the researchers will continue to work on the project.
