Comments on the article Comments on the article

Man is a product of the most complex evolutionary processes that have been going on for hundreds of millions of years. Being the pinnacle of the development of matter, modern man has developed as a biopsychosocial being, whose life activity can be characterized by biological, mental and social indicators. Biological ones are expressed in various functions of the human body, its direct connections with the environment, without which it simply cannot exist physically. The mental world is understood as the spiritual world of a person and its manifestations, and the social is the "embedded" of a person in the established relationships in a team, in a community of people.

From the standpoint of ecology, humanity is a global population of a biological species, an integral part of Earth's biospherewhere it originated and developed. A person enters the biotic component of the biosphere, where he is connected by food chains with producers, is a consumer of the first and second (sometimes third order), heterotrophic, uses ready-made organic matter and biogenic elements, is included in the cycle of substances in the biosphere and obeys the law of physical and chemical unity of matter B I. Vernadsky - living matter is physically and chemically one.

The biosphere is divided into three sub-spheres as places of modern habitat of organisms together with the organisms themselves:

1) geobiosphere - the upper part of the lithosphere inhabited by geobionts;

2) hydrobiosphere - hydrosphere without groundwater, inhabited by hydrobionts;

3) aerobiosphere - the lower part of the atmosphere inhabited by aerobionts.

V. I. Vernadsky considered the biosphere as an area of ​​life, including, along with organisms, their habitat. The formation of the biosphere took place over billions of years.

In order to ensure biological life and existence, a person absolutely needs a continuous supply of atmospheric oxygen, drinking water, and food. The reflection of the biological nature of a person (as well as all living things) is the desire to preserve one's life by all available means, including through the use of natural factors, to continue it through reproduction, to ensure maximum safety of life. As is known, the term "biosphere" itself was first proposed by E. Leroy in 1927 and P. Teilhard de Chardin in 1930. In 1944, V. I. Vernadsky developed ideas about the transition of the biosphere into the noosphere, i.e. its state when the development of the biosphere will be controlled by the human mind.

With the development of scientific and technological progress, anthropogenic impacts on the biosphere have acquired a global scale, especially in the second half of the XNUMXth century, and in many aspects they are negative and even destructive. At international conferences held under the auspices of the UN, scientists have repeatedly warned of an impending environmental catastrophe, a threat to the safe life of mankind as a whole, on a planetary scale.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Photos instead of satellites for the new navigation system 29.09.2012

The Munich Polytechnic Institute developed the original NAVVIS positioning technology, which is based not on satellite signals, but on visual information. NAVVIS is a smartphone application that allows users to find their current location on a map. All you need to do is take a picture of the area around you. The application independently compares the photo with the image stored in the database and determines the exact position of the user (up to a meter), as well as the direction in which he moves. In doing so, it uses arrows to indicate the way in a three-dimensional projection.

In order for the NAVVIS system to function reliably, it was necessary not only to develop a special recognition system, but also to do a lot of preliminary work. First, a XNUMXD lidar scan of the area is carried out, which creates a "skeletal" XNUMXD map of the environment. After that, a lot of pictures of buildings are taken, including their characteristic features, such as stairs and signposts. Then certain points on the XNUMXD map are associated with the photographs. Thanks to this information, the navigation system allows you to navigate in any space, for example, quickly find the "Mona Lisa" in the Louvre.

However, unlike museums, many buildings and streets are often rebuilt. How will NAVVIS function in such conditions, since its database will become obsolete? This problem is solved by the users themselves, who take changes on the smartphone camera and thus update the database.

NAVVIS is ideal for areas where satellite navigation is not available, such as buildings, city streets, subways, etc. At the same time, wireless networks can be used for NAVVIS operation, which can also be used for rough positioning. It is very easy to use such a system: NAVVIS loads visual data packets when you start the application. The user takes a snapshot of their surroundings, and in a fraction of a second the program compares it to the image database and shows the user's exact location.
