The leopard, having tracked down a herd of monkeys, comes closer to them and lies down on the ground, spreading its legs wide, opening its mouth and eyes - not breathing, pretending to be dead. When the monkeys see this, they are overwhelmed with great joy, but, distrustful by nature, they first send the most daring monkey to find out everything. The monkey, heart pounding with fear, sneaks up on the leopard, looks into his eyes, sniffs him to make sure that he really is not breathing. The monkeys, seeing that nothing has happened, cease to be afraid and, for joy, begin to dance and jump around the motionless enemy. When the leopard sees that the monkeys have spent a lot of energy and lost all caution, he jumps up, tears several monkeys to pieces, and eats the fattest of them. Conrad Gesner.

If you choose the color of the shadows to match the color of the iris, then you will never be mistaken, and the eye makeup will turn out to be very effective and harmonious. However, often the look turns out to be more radiant and bright if you use contrasting colors, as well as colors that complement the color of the iris:

Blue eyes - gray, lilac, yellow, black-gray;

Gray-blue - pale green, bright blue, black;

Green eyes - brown, purple, red, orange, yellow, sandy, light brown, bluish green;

Blue eyes - pink, warm brown, copper, cinnamon, gray, violet-blue, mauve;

Brown eyes - brown, beige, blue;

Light brown - lavender, tawny, olive, blue;

Black and dark brown - brown, plum, tan, rotten green, lilac.

If you have an iris with speckles, then take shadows that match the color of the specks - this will noticeably refresh your look. For example, for blue eyes with greenish speckles, a delicate green tint is suitable.

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 ... >>

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. ... >>

Snails will eat England 02.12.2002

Biologist Claire Andrews from the University of Sussex (UK) discovered that Patella vulgata snails living on the chalk cliffs of Dover are gradually eating up the coast of England.

Clinging to the rock, they scrape off microscopic algae from it, which they feed on. However, along with the algae, the mollusks also scrape off some soft limestone. Three-year observations of snails have shown that up to 30 percent of coastal erosion can be attributed to these seemingly harmless creatures.

Note that the county of Sussex annually spends millions of pounds to combat coastal erosion.
