Trick with four aces. Focus Secret

Focus Description:

The magician asks someone to name a number between 10 and 20 and puts that number of cards one by one into a pile. Then he finds the sum of the digits of the named number, removes a number of cards equal to this sum from the top of the pile, and puts them back on top of the deck. The card that ends up in the top pile is set aside face down, and all other cards in the pile are returned to the top of the deck.

Again the artist asks for any number between 10 and 20 and does the same a second time. So the third and fourth time, until four cards are selected in this way. These four cards are revealed - and they all turn out to be aces!

Focus secret:

Before the trick begins, aces must be placed in the ninth, tenth, eleventh and twelfth places from the top. Further, the focus is obtained automatically.

For any number between 10 and 19, the difference between this number and the sum of its digits is always 9, so that after these operations we always end up on the ninth card.

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 ... >>

Google Glass glasses will transmit sound through the skull bone 07.02.2013

According to the Federal Communications Commission (FCC) documents, the Google Glass wearable computer will not only be equipped with 2.4GHz 802.11 b/g WiFi and Bluetooth 4.0 modules, but will also receive a bone-conducting speaker, thanks to which users will be able to listen to audio without using headphones. The vibrations that will pass into the inner ear through the skull bone will allow a person to hear not only music, but everything that happens around him.

This is stated in the text of the FCC document in the paragraph "Integrated vibrating element that transmits sound to the user by contact with his head." A few days ago, we recall, Google filed a patent application for a mobile computing device with a built-in bone conductive speaker. Note that this technology is not something new, but the use of devices such as Google Glass can significantly increase its popularity.

The prototype of Google Glass glasses was presented to a wide audience six months ago as part of the Google I / O conference. After that, the wearable computer was repeatedly shown to the public and even became a participant in New York Fashion Week in September last year. It is expected that developers will get their hands on the device within the next few months, while for ordinary users the gadget will be available only next year.
