Comments on the article
One of the designers of the T-34 tank, Koshkin, said that the most reliable part is the one that does not exist. So in the proposed semiautomatic device for the "eternal" lamp, the number of parts is reduced to a minimum.
It is not difficult to click first one switch (SA1) and then another (SA2) (Fig. 1 and 2). The time it takes to move your hand from one switch to another is enough to preheat the lamp. With ever-increasing electricity tariffs, it is possible, perhaps, with the help of this "machine" to save money if you turn on the lamp when necessary, not at full power. The flickering of light in this mode can be eliminated by closing it with a "corrugated" lampshade.

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 ... >>
The threat of space debris to the Earth's magnetic field
01.05.2024
More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>
Solidification of bulk substances
30.04.2024
There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>
| Random news from the Archive Volumetric microscope eye
23.04.2009
A microcamera made by American scientists allows you to see the cell from all sides at once. To create a three-dimensional image of a micro-object, scientists from Vanderbilt University, led by Associate Professor Chris Yanetopoulos, etched a depression in a single crystal of silicon.
Since, when such a material is etched, different planes of the crystal lattice dissolve at different rates, this recess took the form of a tetrahedral pyramid. The walls of the pyramid were covered with layers of gold or silver, giving them the properties of a mirror. A micro-object placed in a recess is reflected from the mirror walls, and the researcher sees it from all sides.
In fairness, it should be noted that such devices have already been used to study nanoparticles. And the Yanetopoulos group was the first to use a plate with pyramids of different sizes to study living microorganisms.
"This device is great for studying dynamic processes in living cells, because it allows you to follow them in three-dimensional space. For example, we were able to trace the path of centrioles during division," says Chris Yanetopoulos.
His colleague Dmitry Markov plans to study the deformation of a cell under pressure, which creates a microscopic trickle of water. Dimples in silicon are inexpensive to make, and their size can be varied over a wide range, which makes it possible to study a variety of objects.
