What are gems?

Precious stones have always amazed people. For thousands of years, people wore them as amulets to protect themselves from disease and evil spirits. It was believed that with the help of some gems, their owner was able to predict the future. Other stones allegedly made it possible to determine whether the suspect was guilty or not.

In ancient times, precious stones differed only in color. Rubies are all red stones. All green stones were called emeralds, and blue stones were called sapphires.

Later it became clear that some stones are stronger and more durable than others. It also became clear that the cost of precious stones depends not only on color, brilliance, uniqueness, but also on their strength. For example, today diamonds are considered the most expensive stones because, in addition to their beauty, they have the highest durability compared to other precious stones.

All gems are called precious stones. But, strictly speaking, only the four most expensive stones can be classified as precious: diamond, ruby, emerald and sapphire. Others belong to semi-precious stones, these are opal, amethyst, topaz. Many of the precious and semi-precious stones are closely related.

Diamond, the most expensive of gems, is also the simplest in structure: it consists of one chemical element - pure carbon. Rubies and sapphires are classified as corundum. Rubies have a carmine color due to the presence of a small amount of iron in corundum. And the presence of various oxides gives sapphires different shades of blue and blue.

Most gems include various combinations of "silicates". Topaz and tourmaline belong to the silicate family, as do garnets and jadeites. Some less expensive gems belong to the quartz group, which is made up of pure silica. They include amethyst. Opal is silica containing 5-10% water. By the way, it is believed that opal is one of the few precious stones that bring misfortune to their owners.

Currently, the first attempts are being made to create artificial gems. Among them are diamonds, emeralds, rubies and sapphires. This is not a fake, in fact, these are stones similar to natural ones, only they are created in laboratories!

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 ... >>

Ozone on Venus 22.04.2012

The Venus Express space probe launched by the European Space Agency has detected a thin ozone layer in the atmosphere of Venus at an altitude of 100 kilometers from the surface of the planet.

Since ozone shields some of the ultraviolet rays that are harmful to all living things, it is believed that its presence may indicate the presence of life on the planet. However, this gas in the atmosphere of Venus is more than a hundred times less than in the atmosphere of the Earth, and for the emergence of life on the planet, at least 20% of its terrestrial concentration is needed.

So, most likely, there is no life on Venus, even in the upper atmosphere, where it is not as hot as on the surface.
