Focus Description:

The magician tells the audience:

1) Think of a number less than 10 (other than zero)
2) Add 29 to it
3) Drop the last digit of the result
4) What's left, multiply by 10
5) Add 4 to the result
6) Multiply the result by 3
7) Subtract 2 from the result

After that, the magician announces: "It turned out 100."

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 ... >>

Olympus Tough TG-870 rugged camera 23.03.2016

The Japanese company Olympus has launched a new compact rugged camera series Tough - Olympus Tough TG-870 - with unique selfie capabilities in any conditions, even underwater.

The camera is protected in all respects: it can be immersed in water to a depth of 15 meters, thrown from a height of 2,1 meters, used at temperatures down to -10 ° C, the body also withstands a pressure of 100 kg and is dust resistant.

As for technical features, the Tough TG-870 has a wide-angle zoom lens with a focal length range of 21-105mm EGF, a 3-inch swivel display and a 16-megapixel back-illuminated CMOS sensor.

The unique 5-axis stabilization system allows you to take sharp pictures even in low light conditions that require slow shutter speeds. 13 artistic filters will help you to decorate your shots.

From the unusual - the camera is perfectly equipped for selfies. Firstly, the screen rotates 180°, which makes taking selfies especially easy. Secondly, the shutter button is duplicated on the front panel, which will allow you to hold the camera in the way that is convenient for you.

In addition to photos, the camera allows you to shoot video in Full-HD at 60 frames per second in progressive scan. By the way, due to the fact that its body is protected from water ingress, it will be possible to shoot amazing videos (and photos, however, too) from the underwater depths.
