Random interesting fact from the Great Encyclopedia:

Where did card games first appear?

Card games have been around for so long that no one can say exactly where they first appeared. Most experts believe that playing cards came to us from Asia. There is a legend according to which the Hindus and Muslims in the old days used round playing cards for entertainment, but this is not documented.

The first documentary evidence of this dates back to the 1120th century. The Chinese claim that cards existed in China as early as XNUMX and that they were invented during the reign of Emperor Qian Huo for the entertainment of his courtiers. We know that by the end of the XNUMXth century, cards were very popular in France. They became so popular that even a law was passed forbidding working people from playing on weekdays!

The first cards were mostly rectangular or square, although in some places round cards were also played. The first decks of cards usually consisted of 86 cards. One of the cards had no number and was called "fool". In modern times, this card is called the Joker.

In the XNUMXth century, the art of wood engraving became widespread in Europe. Before that, the cards were hand-drawn and very expensive, so only very wealthy people could afford to buy them. But with the help of wood engraving, cheaper cards were made possible, and for the first time the lower strata of society were able to spend their leisure time playing card games.

In the XNUMXth century, four suits first appeared in France, which are still in use today: hearts, spades, clubs and diamonds.

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 ... >>

Life without passwords 08.02.2015

Developers from the US military academy at West Point are creating a new employee identification system that will be able to replace passwords and biometrics. The government has allocated "millions of dollars" to the project, writes Sky News. The specific amount is not specified.

The project is called cognitive fingerprint ("cognitive fingerprints") and is dedicated to the ways of identifying a person according to the peculiarities of using a mobile device or PC. For example, how fast he types on the keyboard, moves the mouse cursor, or how often he makes spelling mistakes.

The new technology could change the market for identification systems, according to project documents that Sky News has accessed.

“When you interact with technology, your brain processes information in an individual way. In this way, you kind of leave a “cognitive imprint” inherent only to you, just like leaving your fingerprint on a fingerprint sensor,” the documents say.

"Our goal is to create a next-generation identification system that can be used on standard Department of Defense equipment," the authors say.

Similar technologies are currently used in commercial software such as plagiarism checker applications. They compare two texts and decide whether the second text is the original or a modified copy of the first. In the same way, here the system will understand whether an authorized user or a stranger is working with it.

“We live in a world where any user can become a victim of fraud, threats or intelligence agencies due to the lack of sufficiently reliable means of identification on the Internet. For this reason, any new technology that could determine the identity of a person in the background could make the world wide web more civilized place," ViaTheWire's strategist Sharif Sakr told Sky News.

The authorities plan to introduce the new technology in all military departments and do not exclude that it will enter the commercial market in the future. It is assumed that it will be able to increase the level of protection of bank accounts, accounts of payment systems and online stores. The new technology could also be used to access smart consumer electronics, Sky News writes, citing documents.

We add that Google is also working on improving identification tools, but the methods proposed by it are more traditional. In January 2013, the corporation presented a project in which it is proposed to provide web services with two-factor authentication using physical means, such as a smartphone or USB dongle. The first devices are already on sale.
