How is space conveyed in painting and graphics?

According to the laws of perspective. There are linear (reduction in size depending on the distance) and aerial (change in color and sharpness of the contours of distant objects) perspective.

 Random interesting fact from the Great Encyclopedia:

Which star is the brightest?

Have you tried to find the brightest star in the sky?

You probably think that there are a myriad of stars in the sky. But without a telescope, you can see no more than 6000 stars, of which about 1500 are in the Southern Hemisphere and are not visible in the Northern Hemisphere.

Even 2000 years ago, Greek astronomers divided the stars into magnitudes or classes depending on their brightness. Before the advent of the telescope, there were six classes, or magnitudes, of stars. Stars of the first magnitude are the brightest, while those of the sixth magnitude are the faintest. Stars below the sixth magnitude are not observed without a telescope. Today, modern telescopes can photograph stars of magnitude 21.

The brightness of stars of the same magnitude is two and a half times lower than the brightness of stars of the previous magnitude. The first magnitude includes 22 stars, the brightest of them is Sirius, which has a magnitude of 1 6. Sirius is more than 1000 times brighter than any of the faintest stars that can be observed with the naked eye.

The lower the class, or magnitude, the more stars it has. So, if we attribute only 22 stars to the first magnitude, then there are about a billion stars of the 20th class.

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 ... >>

Transplanting a beak to a vulture 13.06.2023

As a result of a unique operation performed by veterinarians, the beak was successfully transplanted to the vulture. This white-backed vulture suffered serious damage when it was hit by a car in northwest South Africa. The accident caused the bird to lose one eye and break off its beak, which posed a serious threat to its survival as it could no longer feed. In the natural environment, she would be doomed to starvation.

However, the vulture was taken to the veterinary department of the University of Pretoria, where a team of experts took on the daunting task. The first two attempts to attach an artificial acrylic beak to a bird were unsuccessful, as they did not have sufficient strength and broke when eating. The doctors decided to take a different approach and turned to the beak of another vulture.

The world premiere of transplanting a beak to a vulture took only 30 minutes. The beak was attached to the damaged vulture with six screws. Currently, the bird feels good and shows positive results.

Experts predict that in a few years the vulture will grow a new beak again, and doctors will be able to remove the prosthesis. This successful operation opens up new prospects for restoring beak functionality in affected birds, which is essential for their survival and adaptation to the wild.
