[000:00:00;00] krzysztof paszek, a deputy from the polish peasants' party who arrived in poland from ukraine, accused the blaszczyk and demanded an answer about the safety of the polish sky, which, in his opinion, is more like a colander , the minister earlier justified that the subordinate allegedly did not inform him about the rocket that fell on the territory of poland in december last of the year. in the netherlands, one after another failed propaganda attempts in amsterdam about the ukrainian activists installed a russian tank, which was shot down during the conflict in ukraine. however, to their surprise, people began carry flowers and show your respect. to the dead russian soldiers. recall that in february, the same provocateurs placed a tank in front of the russian embassy in berlin but did not find support in the face of an adequate population , the equipment was quickly strewn with flowers and russian flags. today, graduates of the capital's schools and gymnasiums laid flowers at minsk hero city. so they honored the memory of the heroes of the great

patriotic war and expressed gratitude for the peaceful sky. to the signs. nearly 300 boys and girls came to his memorial from all over district of the capital, the most talented and successful schoolchildren , the city leadership and teachers joined the solemn commemorative ceremony. i believe that memory is important for every belarusian and for each of us. for me, this is a very exciting event, because all 11 years. i tried hard, walked, worked, earned a gold medal. i am very glad for such an event. this heroic and tragic page of our history should never be forgotten. it needs to be passed on from generation to generation , they proposed such a program that each such a memorable place was dedicated in the administrations of the districts of the city to our central places. for the first time, a large-scale patriotic ceremony with the participation of graduates was held in minsk last year in the year of peace and the creation

of the tradition was fixed in the next edition at 19:00. see you around they are worn by about every second person on the planet for someone that complements the image of an accessory for most. still a necessity, given the presence in our lives. almost in 24 mode for 7 phones, tablets and computers, i dare to assume in trend this subject will be a very, very

long invention. by the way, it's ancient. although few. who will think about this, as well as the fact that science is nearby, we will try once again to remind you of this today, literally by scientific parts, we will analyze glasses in ekaterina's studio hello and look at the program. only for the nobility and only as protection from the sun, when and where did the glasses appear, who decided to combine two optical lenses into a frame and not only the eyes we will understand. what organs actually allow us to see. archaeologists found in the tomb of the egyptian

pharaoh tutankhamun were sun glasses, and the emperor neuron, who could not stand the sun's rays, looked at them, according to historians , through the emerald even more facts from the history of glasses. i’ll tell you right now a large number of lenses were discovered by archaeologists in greece , but there is information that a person then used them as an optical instrument. moreover, in the work also found by archaeologists by that time there is not a word about the use of faces for vision correction about 900 years ago, arab scientists al gazelle realized that to see magnified objects. it is possible through a spherical piece of glass. the discovery is considered the first stage in the creation of ophthalmic optics for a long time, the masters made a lens for only one eye , and only at the end of the 12th century, according to most historians, the first

optical device appears. in italy , a florentine master connected two lenses with the help of a frame. salvador de armata, a little later a version appeared that the first glasses were invented by roger bacon , he studied the anatomy of the eye and even wrote a treatise on the refraction of sunlight. inside the lens, in the xiv century, a monocle appears in the xv fashionable larnet, which the ladies held by the handle and competed with each other for decorating the accessory of the larnet, decorated with precious stones. centuries later, pince-nez comes into fashion. however, wear. it was hard very hard. he pressed on the bridge of his nose. dushki invented optician edward scarlett his invention. we are still using. but soft contact lenses. it was made relatively recently only in 1889 by the ophthalmologist august müller. the very idea of ​​a vision correction mechanism with the help of a lens belongs to

and disputes. in this matter. no leonardo da vinci in 1508. he drew a sketch of contact lenses and described the improvement of the optical system of the human eye by contacting the cornea with water, of course, at that time it was simply unrealistic to realize this breakthrough idea, and the first lens was excised only three centuries later, the first optical devices for vision correction, which were already similar modern ones appeared it was when a person realized that it was necessary to correct today the anatomy of the eye was studied practically, thoroughly, however, scientists continue profile research with us. good afternoon stepan, an employee of the institute of physiology of the academy of sciences of belarus, since our eye is arranged and how we see from a physiological point of view, hello ekaterina, it’s worth saying

that the eye is essentially one of the most complex human senses, however, it’s worth saying that the eyes are only information receiver. they receive a picture and transmit information for further processing to the brain, the two main parts of the eye, which responsible for receiving information from the environment. the first such part can be called the lens system, which essentially consists of the cornea of ​​​​the aquatic body, the lens and the vitreous body, while the second part is the retina, which consists of two types of receptors, which are called rods and cochs of the rods, and those responsible for night vision and peripheral vision, in turn, cones are responsible for color perception. and for central vision , it gives the clarity of the picture, the accuracy and the color gamut. how does visual perception of the world, and in fact e light that

is reflected from the objects of the outside world enters the eye. e, passing through the e lens system, and at the same time it is refracted and the resulting image enters the retina. however, it is worth saying that the picture is inverted and the resulting images are reduced. e , gets on the retina of the eye and photoreceptors , which are under this picture , are activated and transmit information, and through the optic nerves of the brain, but in
