What is industrial diamond?

The only difference between an industrial diamond and any other is that it is of a lower quality. If a diamond is of impeccable quality, beautiful, without a single speck, color, then, of course, it will be used in jewelry, where a higher price will be given for it.

It may come as a surprise that something as valuable as a diamond is used in industry at all, but the diamond is called the "King of Industry"!

The Greeks called the diamond "adamas", which means "invincible". A diamond is truly invincible as nothing in the world can cut it apart - except another diamond! Therefore, three-quarters of all mined diamonds do not go to jewelers at all. They are used in industry. And they are used because of their extreme hardness.

For example, about 20 percent of diamonds go to rig heads that are used to drill into rock. Diamonds are ground into a powder and this diamond powder is used for grinding wheels on which diamonds are processed. Some diamonds are used in metalworking. Without diamonds, some of the most important industries would not be able to operate.

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 ... >>

Physics and Linguistics 04.02.2012

Murray Gell-Mann, an American physicist and winner of the 1969 Nobel Prize in Physics, is known for his work in the field of elementary particles and for predicting the existence of quarks. Unexpectedly, he published an article on linguistics last fall, albeit in collaboration with a professional philologist.

They examined the typical word order in sentences in 2011 languages, including dead ones, and concluded that in short phrases of the first human language (judging by the data of archeology, genetics and linguistics, it arose about 50 years ago), the subject came first, then the object and at the end the predicate. For example: "The man killed the bear." In the future, there was an evolution: "A man killed a bear" and (in the most "advanced" languages) "A man killed a bear." However, this evolution applies only to languages ​​with a fixed word order, such as English.

Curiously, Gell-Mann is not the first prominent physicist to become interested in linguistics. The English scientist Thomas Young (1773-1829), who proved the wave nature of light, contributed to the deciphering of Egyptian hieroglyphs.
