What is gold for fools?

If you are a prospector and are looking for gold, then for you the answer to this question is as important as the difference between huge wealth and immense poverty. Many miners have stumbled upon what they thought was gold, only to find, after analysis, that their hope of riches had vanished like smoke.

What is known as "fool's gold" is actually iron pyrite. Since this yellow mineral is also dazzling, it can easily be mistaken for inclusions of native gold in the rock. Another reason for error is that gold is often found in the same places as ferruginous pyrite. Native gold is often found in quartz veinlets or in massifs of ferruginous pyrite. Water and wind carry away quartz and pyrite, and gold is weathered from the rocks.

This means that the stone around the gold nuggets is washed out, leaving almost pure gold nuggets. Nuggets are washed away by water to the bottom of the valleys, and they are mixed with sand and gravel. In this form, gold is called alluvial, or loose. The first gold found by man was loose. But gold is often found in ores of other metals. Silver ore almost always contains some gold. Often gold is also found in copper ore.

Gold is found even in sea water! Its content, however, is so small compared to the total volume of water that no one is able to extract gold from sea water. However, the oceans are so vast that the total amount of gold they contain is estimated at 9 tons.

Chemists of the future will have to solve a very interesting problem - to extract gold from sea water.

How do Arabs write and read numbers?

The Arabs use their own signs for writing numbers, although the Arabs of Europe and North Africa use the "Arabic" numbers familiar to us. However, whatever the signs of the numbers, the Arabs write them, like letters, from right to left, but starting with the lower digits. It turns out that if we meet familiar numbers in the Arabic text and read the number in the usual way from left to right, we will not be mistaken.

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 ... >>
