What chemical element was obtained as a side effect of trying to isolate gold from urine?

In 1669, the German alchemist Brand Hennig, in search of the philosopher's stone, decided to try to synthesize gold from human urine. In the process of evaporating, distilling and calcining, he obtained a white powder that glows in the dark. Hennig mistook it for the "primordial matter" of gold and called it "light-bearer" (which is pronounced "phosphorus" in Greek). When further manipulations with this matter did not lead to obtaining the precious metal, he began to sell the new substance even more expensive than the gold itself.

What is quicksand?

In many places around the globe, people have lived in fear of quicksand for centuries. They were credited with the mysterious ability to suck in the victim until there was not a trace of it left on the surface of the earth. In reality, quicksand has no such power. If you know what it is and how to behave on it, then it will not cause any harm.

What is quicksand, or, as it is also called, quicksand? It is light, loose sand with a high water content. In appearance, it does not differ in any way from ordinary sand, located next to it.

However, there is still a difference between them: quicksand is not a support for heavy things. Usually quicksands appear near the mouth of large rivers and on gently sloping banks. Under them is a layer of viscous, dense clay, which does not allow moisture to pass into the earth. Therefore, rain water and mostly river water accumulates in it.

Unlike ordinary sand grains, which have an irregular or pointed shape, quicksand sand grains are small, round balls. The water accumulating under them dilutes the sand, and the grains of sand seem to float in it. That is why they are not able to hold heavy objects on the surface.

Quicksand does not have to be sandy. Any loose soil, a mixture of sand and silt, or the same silt with small pebbles, is suitable for it. People who fall on quicksand do not drown in it at all. Since it contains a lot of moisture, they can swim in it, just like in water. In addition, quicksand is denser than water and therefore easier to stay on the surface. We must remember, however, that, once on the quicksand, you should move slowly enough. This allows the sand to flow around your body, as it does when you swim in water. In this case, you will not have reason to fear for your life.

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 ... >>
