Why did the rebellious Parisians in 1789 need to take the Bastille?

The French national holiday on July 14 is known as Bastille Day. However, on this day in 1789, the rebellious Parisians had no goal at all costs to seize this fortress or to release the prisoners, of whom there were only seven at that time. It’s just that the Bastille contained large stocks of gunpowder, which the townspeople needed to fight with government troops. In addition to gunpowder, the revolutionaries demanded that the commandant remove the cannons from the embrasures, and after the refusal a firefight ensued, culminating in the surrender of the garrison.

 Random interesting fact from the Great Encyclopedia:

What does a butterfly eat?

As you know, the life of a butterfly goes through several cycles. First the egg, then the caterpillar, then the chrysalis (which sleeps all winter), and finally the butterfly emerges from the chrysalis. There is one period in the life of a butterfly when it eats especially a lot. This is the time when she is a caterpillar.

For some species of butterflies, the caterpillar stage is the only period of life when they eat anything at all. The caterpillar eats and grows in size until the skin bursts, which gives way to a new one, and so many times in a row, and after a few weeks the caterpillar becomes many times larger than at the beginning.

But in general, butterflies are quite adapted to eating: they have a head, chest, abdomen. Those butterflies that eat have a proboscis instead of a mouth, which is in a folded state between meals, like a clock spring. This proboscis can penetrate deep into the core of the flower in order to suck out its nectar.

In moths, this proboscis can reach a length of 15-20 cm, so that it is able to penetrate large tubular flowers. Some of them have incisor-like teeth at the end of their proboscis, with which she can gnaw through the peel of fruits and drink their juice!

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 ... >>

Glass linings for chips 28.03.2024

Revolutionary technologies are constantly changing the electronics industry, providing new capabilities and improvements in component manufacturing. One of the latest innovative developments is the idea of ​​using glass substrates for chips. Samsung and Intel are actively working on this technology, which could lead to significant changes in the electronics manufacturing industry.

Glass substrates promise to transform the chip manufacturing process, providing significant benefits to the electronics industry. They are characterized by high thermal and mechanical stability, making them an ideal material for use in data center applications. In addition, glass substrates have a high flatness, which improves the quality and accuracy of the lithography process, as well as the dimensional stability of interconnects.

Intel has been actively working on glass substrate technology for ten years and plans to introduce it into commercial products by 2030. This is expected to significantly increase interconnect density, which is critical for efficient signal operation and power delivery to chips.

Competing with Intel, Samsung is also actively developing this technology and plans to begin mass production of chips on glass substrates by 2026. To do this, the company has assembled a team of experts to research, develop and implement this technology. Samsung Electronics will focus on semiconductor and substrate integration, while Samsung Display will specialize in glass processing.

The use of glass substrates for chips represents an important step in the electronics industry. The technology promises to improve manufacturing processes, improve chip efficiency and quality, and lead to new possibilities in electronics. The collaboration of leading companies such as Samsung and Intel allows us to hope for the successful implementation of this innovative technology in the coming years.
