How did a person learn to write?

No one knows exactly where and when writing arose. We can only speculate how it has developed since ancient times. The man began to draw pictures telling about hunting and war, about the life of the tribes. Pictures were also used to convey messages. The image of the Sun meant day. Two marks next to the Sun meant two days. These icons are called pictograms.

With the development of civilization, this method of writing was accelerated by simplifying pictures. The Egyptians used a wavy line to represent water. The Chinese drew an ear between two doors, which meant "listen". Such signs were called ideographs or ideograms. The ancient Egyptians used a system we call hieroglyphs. At first it was a completely ideographic system. But in the course of centuries, the Egyptians also created a phonetic system, that is, such signs that meant the sounds of speech, and not only depicted objects or phenomena.

With the development of civilization, a need arose for a large number of signs. Thus arose a method of writing words according to their sound. The signs that convey sounds are called phonemes. Words can be divided into syllables. The next stage in the development of writing was the creation of the alphabet. The ancient Egyptians and Babylonians knew how to write alphabetically. According to their method, the Greek and Latin alphabets were created, which are widely used in the world, with the exception of Asian countries.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Solved the problem of quantum computers 14.03.2015

Researchers from Google Corporation, along with colleagues from the University of California at Santa Barbara, have found a solution to one of the problems preventing the emergence of quantum computers, reports Wired.

In modern computing systems, all simple data operations are checked for errors. This procedure allows you to avoid the consequences of external influences on the system and make sure that the final result is correct.

But if it is easy to perform such a check in a modern PC or on a server, in a quantum system it is impossible by standard methods, since the procedure for measuring a qubit (the smallest element for storing information) will change its state and itself will cause an error.

To avoid changing the state of the qubit during the measurement of its state, the researchers added additional qubits to the quantum system - four for the five existing ones. These four qubits perform only one function - they check the status of other units of information storage. They do it in such a way that the state of the main five qubits does not change.

However, such a solution leads to another complexity, said Daniel Gottesman, a quantum mechanics expert at the Perimeter Institute for Theoretical Physics in Canada. He draws attention, in particular, to the fact that checking for errors in a quantum system will require a significant amount of electrical energy - in addition to the already considerable amounts that the quantum computer itself will consume.

However, without verification, a quantum system would be meaningless, the researchers say. "To create a practical quantum computer, you have to solve the problem of random change in the state of qubits, there is no getting around it," said Austin Fowler, one of the project participants, a quantum electronics engineer from Google.

A quantum computer is based on such a concept in quantum mechanics as superposition, the scientists explain. Superposition is a phenomenon in which a physical object, such as an atom or an electron (which a quantum computer uses to store information), is simultaneously in several alternative states from the point of view of classical mechanics. "Scientists believe that computers based on this aspect of quantum mechanics , in the future will work millions of times faster than today's computers.

In September 2014, Google announced its intention to independently develop, manufacture and test processors for quantum systems. To do this, the corporation invited a team of scientists led by John Martinez (John Martinis) from the University of California at Santa Barbara. This group in April 2014 developed the simplest prototype of a quantum processor capable of operating five qubits with a high degree of reliability. The scientists' achievement was widely publicized in the scientific press, including the popular journal Nature, and the team leader received the Fritz London Prize, which is awarded for outstanding contributions to the field of low temperature physics.
