What is a cathedral?

In the Middle Ages, all of Western Europe belonged to the Roman Catholic religion. Each congregation had its own church. These churches were grouped within areas called dioceses. Each diocese was under the jurisdiction of a bishop. The main church of the diocese had an episcopal throne - the pulpit. Translated from Latin, the name of such a church sounds like "cathedral church".

Most cathedrals were built in the shape of a cross. The long part of the cross is the nave of the church, which serves to gather the worshipers. It is crossed, as it were, by the crossbar. At the "top" of the cross was an altar and a place for the choir. Domes in such churches were most often built over the intersection of two elongated spaces. Cathedrals were built in almost all architectural styles. But most of the most famous cathedrals were built either in the Byzantine, Romanesque, Gothic, or Renaissance styles.

Most of the most famous cathedrals, such as Notre Dame de Paris, were built in the Gothic style of the XNUMXth-XNUMXth centuries. Strangely enough, the world's largest Gothic Cathedral of St. John the Evangelist was built in the XNUMXth-XNUMXth centuries in New York, and it is not Roman Catholic, but Episcopalian. St. Peter's Basilica in Rome is not officially a cathedral as it does not have an episcopal pulpit. This is a great example of a Renaissance building. Its dome was designed by the great Michelangelo and is a masterpiece in itself.

What is regeneration?

Could it be that in people who accidentally lost an arm, leg or even a finger, they simply grow back in the same place? This is impossible for people, but there are such living beings for whom this happens!

The process of restoration of lost organs and tissues by the body is called regeneration. Regeneration occurs in few living beings. For example, in certain species of worms and starfish, the entire body can be restored from a tiny particle of the body.

In our body, the process of regeneration of a certain type can also proceed. The top layer of our skin is constantly being worn away and replaced by other cells. Our hair and nails regenerate all the time. Even our baby teeth can regenerate in a certain way. And, of course, feathers, wool and scales lost by various animals are restored in the process of regeneration. In more complex organisms (and man is a very complex organism), regeneration is less developed.

Man and all mammals cannot regenerate a whole organ. But salamanders and insects can regenerate entire limbs. What can really regenerate in us is fractured bones, damaged skin and muscles, and certain types of nerves. Regeneration is of two types. The first is when new tissue grows on the surface of the wound. The other is when the restored parts are transformed, but a new organ does not grow.

Regeneration "budding" is formed on the surface of the wound. It is usually cone-shaped and contains germ cell types or cells that are present at the birth of a living being. These cells develop into special cells that form a new organ.

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 ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Tunguska meteorite - once in a thousand years 14.12.2003

Over the past eight years, from February 1994 to September 2002, American reconnaissance satellites in geostationary orbits and covering almost the entire surface of the Earth with their observation have registered 300 cases of small asteroids invading the earth's atmosphere.

The main task of this system is to detect possible atomic explosions, but, having not found any, the military shared data on flashes similar to explosions with astronomers. Asteroids with a diameter of 50-100 meters crashed into the atmosphere at a speed of several tens of kilometers per second.

New data forced astronomers to reconsider the frequency of collisions of such celestial wanderers with the Earth. It turns out that a celestial body bursts into the atmosphere once a year, capable of releasing energy corresponding to 5 kilotons of TNT, and such cases as the Tunguska catastrophe (an explosion with a force of 10 megatons) can occur only about once every thousand years.

Until now, based on ground-based observations, experts believed that Tunguska-type meteorites could fall once every 200-300 years.
