What makes diamonds gems?

Why are diamonds so highly valued? Of course, diamonds are rare, and anything that is rare has a high value. But the mere fact that it is rare is not enough. The thing must also be very attractive, and diamonds are really beautiful.

In terms of its ability to reflect light, nothing in the world can compare with a diamond. Diamond is also the hardest known substance. This embodiment of beauty, which can remain unchanged for thousands of years, has become a symbol of enduring love and fidelity. In their original form, diamonds are ugly. They must be processed to be beautiful.

In nature, diamonds of various sizes and shapes come across, and outwardly they look rather plain at first. A skilled cutter must carefully examine each stone and determine how best to bring out its beauty. Sometimes a diamond is sawn with a rapidly rotating disk covered with diamond dust. Only diamond dust can be used to polish another diamond. Most diamonds are sawn in two, each half cut and rounded. A diamond in this form is called a diamond. Diamonds are cut on a high-speed all-metal wheel coated with diamond dust and oil.

Facets are arranged symmetrically, and an ordinary diamond has 58 of them. The more facets, the more the diamond shimmers. Diamond cutters have invented a whole range of cuts: cabochon, baguette, marquise, etc. Diamonds used in jewelry can vary greatly in color and quality. Some colors are rarer than others. The most valuable are diamonds with a red or blue tint, as well as transparent and colorless.

What non-standard anatomical feature does the Statue of Liberty have?

The structure of the foot, in which the second toe is longer than the first, is called "Morton's toe". Such a structure is found in about 10% of people and often does not cause any inconvenience, although with improperly selected shoes it can cause pain and calluses. The ancient Greeks and Romans considered just such a variant of the leg to be an aesthetic standard, which was reflected in the sculptures. Therefore, the foot with the Morton toe is also called the Greek foot, as opposed to the Egyptian foot, each toe of which is shorter than the previous one. By the way, the Statue of Liberty also has a Greek foot.

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 ... >>

Electronic tattoo and microphone 15.11.2013

Motorola has filed an application with the US Patent Office that describes an "electronic tattoo" with a built-in microphone. The application says that the "tattoo" is attached to the user's neck and, in addition to the microphone, includes a transceiver and a power source. The task of the microphone is to record the vibrations of the human larynx during a conversation.

The data from the microphone is transferred to the mobile device. The developers note that this method of capturing sound will reduce background noise, and the interlocutor will hear the user with a tattoo more clearly. A display and a galvanic skin response sensor may also be placed on the tattoo to measure the electrical conductivity of the skin. The latter allows you to use the tattoo as a lie detector.

The application does not say how the tattoo is supposed to be applied to the skin. Note that earlier Motorola called the word "tattoo" a thin and flexible device attached to the skin like a patch.

Motorola suggested using the "patch" tattoo as an identifier. It was assumed that the device emits a signal that serves as confirmation of the person's identity.
