Focus Description:

We cut out a square from paper, put it on a glass and carefully turn it over. The paper has stuck to the glass, as if magnetized, and the water does not pour out. Miracles!

Focus paper cover

Props:

Glass, water, paper.

Focus secret:

When we cover a glass of water with a piece of paper and turn it over, water presses on the sheet on one side, and air on the other side (from the very bottom). The air pressure is greater than the pressure of the water in the glass, so the sheet does not fall.

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 ... >>

Robot dog Sony aibo new generation 01.11.2017

The Japanese corporation Sony has introduced a new generation of robotic dog - intelligent pet aibo will go on sale in January next year.

Compared to its predecessors, the new robot dog looks and behaves more naturally. The dog has all parts of the body moving, and the total number of degrees of freedom reaches 22. The robot is equipped with an array of four microphones and a speaker; small OLED displays are integrated into the eyes.

Over time, aibo learns and adapts to its owners. For example, a dog remembers actions that make people smile and enjoy. In addition, the dog takes into account when the owners stroke and praise him, and when they scold him for "tricks".

The robot is endowed with a wide variety of sensors. These are touch sensors on the back and head, three-axis gyroscopes and accelerometers, motion sensors, light sensors, etc. In addition, there are cameras.

Inside aibo beats a silicon "heart" with four computing cores. The dog supports data exchange via LTE cellular networks and IEEE 802.11b/g/n Wi-Fi wireless networks.

Deep learning tools allow a robotic dog to change its behavior over time. The dog is able to demonstrate its own emotions, in particular, to reciprocate the expressions of love from the owners.

The aibo measures approximately 180 x 293 x 305 mm and weighs 2,2 kg. The battery charge is enough for two hours of active existence, recharging takes about three hours.

Initially, the novelty will be available in Japan for about $1700. In addition, owners will have to purchase an accompanying service subscription (for access to the cloud and LTE) for three years at a cost of $26 per month.
