Focus Description:

The spectator shuffles the deck, then chooses any twelve cards, and gives the rest to the magician. The spectator shuffles his twelve cards again, while the magician writes a prediction on a piece of paper, which he puts in an envelope and puts aside. The spectator places any four of his twelve cards face up in a row on the table and gives the rest to the magician.

The magician places cards from the deck face down on each card on the table so that the value of the entire pile reaches ten, that is, if it is a three, seven cards must be placed on it. For this purpose, figure cards are valued as tens, and no additional cards need to be added to them.

The values ​​of the top four cards are added up (the figure cards again go as tens), and the magician counts this number of cards from the rest of the deck. He turns over the last card dealt. The envelope is opened - and it turns out that the magician predicted this particular card.

Focus secret:

1. A spectator, let's call her Anna, shuffles the cards. She is asked to choose twelve cards and shuffle them. When she gives the rest of the cards to you, you should take a quick look at the bottom card. Let's say it's a seven of clubs. You write this card on a piece of paper and put it in an envelope, seal it and put it on the table.

2. Ask Anna to place any four of her cards face up on the table and give the rest to you, you place these cards on the bottom of your pile. You then deal your cards to each of Anna's face-up cards, adding the value of each pile to ten (face cards count as tens), as described above. Now ask Anna to add up the values ​​of the four cards she has placed on the table. Make sure it folds correctly.

This is an arithmetic trick that cannot fail (unless you make a mistake in the calculation or if the deck is missing a card!). When you take Anna's eight cards and put them on the bottom of the deck, the seven of clubs becomes the ninth card from the bottom or the fortieth from the top, since there are four cards on the table.

Now suppose that the total point of the cards on the table is eighteen. The number of cards that you will have to add to them in order to increase the value of each of the piles to ten will be twenty-two. You will have twenty-six cards left in your hand, and the eighteenth card from the bottom will be the seven of clubs.

In other words, the value of the four flipped cards, plus the cards to be added to them, will always be 40, and the fortieth card in the deck is the one you quickly looked at and wrote down.

3. Count out the appropriate number of cards from your hand and reveal the seven of clubs, which you predicted, of course.

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 ... >>

Drugs will be tested on a human simulator 12.08.2012

Scientists at the Massachusetts Institute of Technology (MIT) have received $32 million from the defense science agency DARPA and the US National Institutes of Health to develop technologies that will significantly accelerate the pace of pharmaceutical trials.

As part of the BIO-MIMETICS project, an electromechanical simulator of the human body will actually be created, which will allow observing various reactions to drugs. The platform being developed will mimic human physiology in the laboratory using an array of microfluidic chips, electronic control systems, human living cells and tissues. The BIO-MIMETICS complex will combine technologies developed at MIT, such as a universal microfluidic module that can simulate up to 10 human microphysiological circuits responsible for the functioning of organs.

Such modules will be able to simulate the work of organs and systems containing a wide range of human tissues. This list will include the circulatory system, the immune and endocrine systems, the gastrointestinal tract, the skin, as well as the musculoskeletal, nervous, reproductive, respiratory and urinary systems.

The goal of the BIO-MIMETICS program is to create a universal platform that can accurately predict the consequences of the use of a particular drug or toxic substance. With the new technology, drug manufacturers will be able to rapidly test new drugs and move to clinical trials faster and safer. For patients, this means that promising drugs that save from many dangerous ailments will appear on the shelves of pharmacies much earlier. Also, the new technology will be useful for research and adaptation of promising treatment methods, such as regenerative and personalized medicine.
