rewound tape cassettes, i still can, probably those under thirty have a hard time understanding what i'm talking about, but maybe someone is in the know, because tape recordings are back in fashion, their sales, surprisingly, are growing, bands are releasing albums like that again, listeners, like in the old days, are struggling with the chewed tape, and are happy to be immersed in the past. here , press this, this thing turned on, listen, it's playing here, these young dancers love music, but it seems like this method of playback is new to them, we're not that side, it seems, the eldest of the kids are only 10

years old, they were born in a completely different era, when instead of a huge tape recorder, there was a small bluetooth speaker, and the role of the player was played by a smartphone. the superstar of the nineties vladimir levkin, the ex-lead singer of the group nana, whose albums were released on cassettes, is trying to explain to the children what's what. cassette, is it about the parent of what? no, flash. and the tape recorder is this converter, what is it called now, no, radio, it has always existed, a speaker, well, yes, a speaker that you turn on from your phone, well, yes, it does everything explained to them, and about the device, and about cassettes, and even about what the burden of music of those times is, there used to be... those guys

who had a tape recorder like this, they were cool and carried it like this, like this, walked around listening to music, it was later that headphones were invented, there were no headphones, everyone walked around like this, try it, cool, headphones, cool, one earphone is so big. the fashion for retro led to the revival of a seemingly forgotten technology. in britain, for example, cassette sales recently reached their highest level in the last 20 years. fans, such as russian radio host oleg mashkov, and they keep the old and collect the new. this is a small part of the collection, because there are a lot of cassettes, well, probably 250 pieces, for sure. previously, it was possible to listen to music exclusively at such on...

flea markets, like this one in the izmailovsky kremlin, among the figurines, old dishes and pioneer paraphernalia, there really are a lot of cassettes, since there is demand, there is also supply, oh, look, all this is the best for children, everything is pretty and for children, however, in an hour of searching oleg did not find anything really valuable to him, the packaging is mixed up or missing altogether, many are not original, but re-recorded cassettes.

here the aesthetic value is lost, here is how you can listen to it, of course, maybe, yes, again, how the recording was preserved here, but from a collection, from an aesthetic point of view, this will not add beauty to the shelf, it is aesthetics, the possession of some thing associated with an idol, that makes many people... buy, and musicians release new cassettes. world stars, billie eilish, harry styles and taylor swift have released their albums in the last couple of years, including this way, making special designs for the cassettes or including special booklets. in russia, there are few such new releases yet, although there are those who would gladly return to this format. in the tenth b, we listened to lyub. mordov has grown stronger. the peak of popularity

of the zotchie group came in the eighties, when cassettes were the main way of distributing music albums. willy-nilly, we listened to more good music than now, because again rewind, look for something there, don't know what to look for, yeah, it won't hit yet, while tyr-tyr there will tear back, as a result, many listened to albums in their entirety, and not individual songs, as now in digital, for the sake of an experiment, musicians tried to make a recording on a cassette and even by modern standards it turned out pretty good, let's recall the principle of operation: the tape recorder heads magnetize the tape, encrypting the sound, the... the compact cassette format was invented in 1962, initially for journalists, so that dictaphones would become smaller, but then migrated to the music industry. let's listen to what we got: we didn't listen to it in the tenth, we hear a good, warm analog

sound, without hanging highs, nothing irritates, actually what we were talking about, magnetic tape transmits... the sound so that it is comfortable to listen to, but this only happens on expensive, professional equipment, household tape recorders, as we remember, did not always give good quality, and in general suffered from many other shortcomings that had to be eliminated with improvised means. rewinding the cassette with a pencil or handles allowed, and to save battery power in a portable player and b- just rewind. set for those whose player did not have a rewind function, unfortunately, at that time the soviet industry also produced such models. now some brands have resumed production of tape recorders. modern models are equipped with a usb port so that you can play mp3, noise reduction systems, remote controls, the price

can exceed 70,000 rubles. but this is for very keen connoisseurs. musicians of the zodchii group admit that for them the most important thing is in cassettes, after all. in another, and i quietly, when i taught my daughter to read 20 years ago, i quietly turned on the recording, she didn’t know, and we learned these letters with her, so when i come to my mother, i turn on this cassette, i can’t listen without tears, so for me a cassette is sacred, by the way, the question is, how not to lose these treasures, because the film deteriorates over time, there are digitization points where, with the help of decks and special programs, they turn an analog recording into a digital one. the average price is 4 rubles per minute. you can do everything yourself by connecting a player or tape recorder to a computer, but there are some nuances. the quality can vary greatly, firstly,

depending on how good your player is, as a rule, this device is cheap and it may not produce very high-quality sound, it may let in interference, for example, if you power it from a socket. in general, do not rush to throw away your old cassettes, maybe they will still be useful, if not to you, then to your children, whose generation shows a clear interest in material media, so that music can be it was not only to listen, but to touch what is valuable in our age of everything digital and virtual. all week, as usual, i followed... news from the world of science and technology and compiled a top five from them. let's start with line number five. moscow doctors have shown how artificial intelligence helps to create new lives. to carry out the procedure of in vitro fertilization, they now

use the latest robotic incubator, which not only creates a favorable environment for the dividing egg, which has just merged in a test tube with spermatozoon, but allows you to practically observe the development of the embryo online, without taking the dish with it, as was required before, out into the air from special conditions. the machine also helps to draw conclusions about the state of the embryo. this is not just a series of photographs, this is not just a beautiful film about how this or that embryo developed, this is essentially a multifactorial mathematical analysis of the parameters of the development of this embryo, including mass, mass, mass of data that are evaluated. as a result, embryologists receive much more information. allowing to make correct medical decisions, which embryo to implant in mother, and which to freeze for storage, and the embryos themselves, thanks to modern technology, experience less stress and then take root better. you are watching a miracle of technology, that's what will happen next. doctor on the wrist.

riding on a star, i will meet the wind, to an unwashed dream, lada vesta sv cross, automatic at the price of mechanics, benefit up to 3000 rubles. this is a miracle of technology, i am sergey malozyomov, we rise higher in our hit parade of news from the world of science and technology, what is on the fourth line? compliments of praise said in the left ear are more effective. scientists from switzerland came to such an unexpected conclusion. their neurobiological study involved 13 volunteers, all that is important, right-handed. they measured the activity of brain zones when sounds came from different directions using mri. it turned out that positive signals from the left

side most strongly activate the auditory cortex in the right hemisphere, which... it seems that the long-standing dream of doctors has come true: more and more people are constantly wearing a device for continuous health monitoring on their bodies, capable of immediately signaling the slightest problem. i mean fitness bracelets and smart watches. they measure blood pressure, pulse, blood oxygen saturation they take an electrocardiogram, but how much? all this is accurate, can you rely on such a small thing in such serious matters? we will test the most popular gadgets: a model of an american brand with an apple for 3200 rubles and a watch of a south korean brand (twice cheaper, but with more functionality), they also monitor the pulse, are able to take an electrocardiogram,

but in addition they can also measure blood pressure, eternal rivals will compete with ... a removable cuff that inflates, squeezing the wrist, like a classic tonometer. i will check them in action, with doctors the famous training center for olympic sports in novogorsk. the head of the department of the sports medicine center, vladimir feshchenko, by the way, actively uses the watch himself, says that it stimulates. physical activity and thanks to them he even lost 20 kg. and members of the russian national teams in various sports, as a recent survey showed, also wear such gadgets. we found out that about 50% of athletes use wearable electronics, both to monitor their health and to monitor their training. and they think this

useful? yes, they think it is useful. well, you can't fool them, they know their bodies. true,. athletes mainly use the functions of counting steps and tracking workouts, but what about medical functions? let's compare the watch with professional devices. they stick ecg sensors closer to my heart and measure my blood pressure with a classic tonometer and a watch. it's a very unusual feeling when the watch inflates on your hand. the first results are not bad at rest, blood pressure and pulse are measured up to... exactly, a cardiogram it is taken correctly, let's complicate the task by adding a load, elevation 7.8, speed 3.55, my pulse shows 113, how much do you have, mine is 115, so my pulse shows 120, yours

is 112, 93, 81, 81, you guessed wrong, 80, 95, my readings haven't changed yet, it seemed to us that the watch was just a little behind with measurements, but the situation with pressure is more complicated, after jogging the korean model, for example, gave, to put it mildly, not quite an accurate result, 154, 118x68. something is very different, let's try it again, 142 80, 102.69, it diverges very much, the difference is 40 and 2.

with chronic diseases. yaroslav tsitovtsev is a hypertensive patient. he has been familiar with a tonometer since he was 14 and never parted with pills. if you take medications, it is usually 135x80 to 75. and if

you do not take them, it reaches 150-160. at the peak, it is exactly 170. there is a headache, sometimes the eye is really pressing from the inside. in principle, some moments, maybe sodzhki appear. will it make life easier. pressure measurements will come in handy. by the way, the korean american models offer to evaluate another parameter, the stress level. useful

is it? apparently, says anton klachkov, head of the neurorehabilitation and physiotherapy department, the watch analyzes the variability of the pulse. by the way, this is also the basis for the pre-trip control method for pilots, drivers or employees of hazardous industries. we will record using a cardiogram, evaluate the variability of the heart rate before the experiment and then repeat it after. in addition, a psychological test is also used. so far, all the indicators for our test subject dasha kortamysheva are normal, but not for long. meet the tarantula spider, nicknamed the flower. tell me he's not real? i 'm afraid he's real, oh my god, dasha is terrified of spiders, i can't, she's like that,

that's it, i'm not scared, help, that's enough, the korean watch noticed that the pulse jumped to 120 beats per minute, the stress level is at its maximum, i can't take it anymore, the american model recorded an increase in the indicator to 59%. professional equipment also sees changes, but not as much. in general, the function is more entertaining, maybe, for example, to remind you to rest on a busy working day. you shouldn't take this parameter too seriously. well, what about? medical parameters, is it true that the watch can record arrhythmia when their notifications can save a life? we'll tell you in just a couple of minutes: continuation

of the investigation about smart watches, how accurate are their ecg, pulse and pressure measurements? we suspect that tattoos can distort the readings: can you trust them with vital questions? clean fresh air? the device can improve the atmosphere in the house, my nose itches, i sneeze, i cough, and my eyes, my eyes itch, are climate control systems capable of cooling the air as well as air conditioners? and also the most amazing discoveries and inventions, leaders of the weekly news hit parade.

nikita's guardian was assured that his biological mother named diana larechkina was no longer alive, my adoptive mother told me that my mother had died, but he found a page of a woman named diana larechkina on a social network, her eyes were very similar to mine, blue eyes, was it really she who gave birth to him 20 years ago.

she had no documents, she could have given the name of someone she didn't know, there is a high probability that such a woman doesn't exist in nature. will nikita be able to find out the truth about why he was abandoned? the child was admitted to the hospital from the maternity hospital, born to a woman who called herself diana albertovna larechkina. all this information was recorded from the words when he had to be discharged from the hospital, for some reason she didn't come for him. i really want... they appeared in my life, i open the envelope, dna, tomorrow at 17:50 on ntv. nevsky, new season, coming soon to ntv. heaviness, pain and swelling. these may be symptoms of varicose veins. the course of phlebodia 600 helps treat varicose veins. phlebodia 600 for the freedom of your legs. tele2 presents. i have heard a lot about your exchange. tele2. show me

oh, sago. bend osago to yourself on repens.ru , issue it for as long as you want, at least for a year, at least for a month in just 3 minutes. flexible osago from renaissance insurance. this is no longer just osago. miracle technology on the air. and what news took third place in our list of the most striking messages from the world of science and technology. the laptop screen is no longer needed. its wonderful will replace compact, but providing a better view, augmented reality glasses. this is what the creators of an israeli startup are sure of, which presented just such a model: it unfolds a giant hundred-inch virtual screen in front of the user's eyes. another advantage is that no one else will see what is happening on this display. smart watches have learned to measure the pulse, take

an electrocardiogram, and this, of course, is amazing. but their algorithms are not always perfect. for example, the previous generation apple model can be confused tattoos on the body. a system error has seriously angered users on the internet. their solution to the problem was offered on the air of an american evening show: a joke gadget for tattooed people, a separate wrist for a watch, allegedly from the apple company. it's not a glitch if we can sell you a solution. this is the fictitious advertising slogan, and below is the traditionally high price tag, but maybe the manufacturers have corrected the oversight. let's check the three models we selected: american, a newer version, korean and russian. smart watches at volunteer with a suitable wrist. a chest heart rate monitor is used as a standard. our sasha

tsyganko will monitor its data via a smartphone. let's go! it seems that the manufacturer managed to fine-tune the algorithms, and the drawings on the body did not become an obstacle for these watches. and what about other models? we suspect that... ings can distort the readings, because the light emitted by the sensors of smart watches, it actually passes differently through the very ink that is applied under the skin, it was not possible to measure, let the watch of the korean brand did not even try to illuminate ink, immediately gave an error, on the area of ​​skin without a pattern everything is fine, there were problems with russian watches, they measured the pulse through the tattoo with a large error. to complete the picture, we decided to check whether the optical sensors would be confused by abundant hair, all devices coped flawlessly here, it's time to find out how they showed themselves in real everyday conditions. yaroslav confidently

chose the most suitable watch for himself in terms of accuracy and convenience in a week, and these are two different gadgets. in terms of convenience, these ones, which without cuffs, they are better, because of the fact that she has a program.

specifically here in this place the watch was installed. we decided not to rely only on subjective sensations. for two days, using different watches, nina gennadyevna wore a holter monitor, continuously recording the ecg pulse. the data was assessed by cardiologist evgeny potekhin, comparing them with what the watch measured. the coincidences were pleasing. i looked at the diary, where you note a slight spinning, accelerating.

is that section of kg, which is registered by the watch, with those complaints, which a person presents, it’s, well , you just know, here’s not... words, probably, we should erect a monument to those people who - brought this idea to a practical solution. there is already more than one known case when a smart watch literally saved a life. the heart stopped more than a hundred times in two days, the owner from britain did not feel anything. he even decided that the device was faulty, but on the advice of his wife he visited a doctor, it turned out that he needed an operation, since the risk of dying in his sleep is very high. by the way, we are talking not only about cardiovascular diseases, so

the parents of a twelve-year-old american girl, after warnings about her heart rate being too high on her smartwatch, went to the doctor in time and found out that their daughter had early-stage cancer. isn't this a real miracle of technology, capable of not only improving, but sometimes prolonging life. you are watching a miracle of technology, here's what will happen after a short commercial. refresh, clean. cool, which devices will really save you from heat and dust, as well as the top line of the hot five world scientific and technological news, what we found most interesting this week? watch the match akron zenit fonbet russian football cup on august 27. buying an apartment is easier with t-bank, apply for a mortgage online with a decision in a couple of minutes. insure your mortgage and the apartment itself. and all this in one tebank application. te-bank. he

replace an entire operating room was created by a company from the usa. all parts fit into a backpack and unfold in a matter of minutes. as a result , the patient. ends up in a sterile bubble, inside which the surgeon's hands perform the operation. the new product is intended for military zones of natural disasters remote areas. in our apartments we breathe dust, carbon dioxide, microscopic mites. so we are scared by the advertising of devices that promise to improve the air quality in the house. cleaners, humidifiers, ionizers, breezers. maybe it's really time to buy one of these? we inhale dust mites fraught with asthma, particles of our own skin, animal hair, fabric fibers and even a dangerous carcinogen,

formaldehyde from some finishing materials and furniture. do devices help against all this, for example, this climate control one? for 11 thousand rubles promises to immediately cool, purify and humidify the air. in the ceramic workshop of our production designer elena kvoshnena, all this would be useful, because there is no escape from dust, the products require polishing. lena has had an air purifier for a long time, it works well, but it does not reduce the temperature and does not humidify the air. it is very hot here in the summer. the windows do not open, the stove works, or it cools down, you need to pour water into this device, load refrigerants into a special compartment, they are already included in the kit, each time they must be pre-frozen, the water passes through the cooler wets the filter, through

which the fan drives air, so, apparently, you can set the timer, cooling, speed, turn on, turn off, noise level or normal, natural sleep? natural, what kind of mode is this? let's leave the lenikomplex for a week, maybe with such an assistant and the air conditioner will not be needed? by the way, both of these devices do not bring fresh air, only drive back and forth, already existing. another device - brizer provides exactly the inflow from the street, with filtration, of course, the installation is not the best. simple: you need to drill a through hole in the wall with a diameter of about 10 cm. is it worth it? our colleague daria lyubina used the breezers for several years, the air became cleaner, this was confirmed by measurements, but over time , disadvantages were also discovered, the device was noisy, in frosts it let in cold, but it still did not replace

normal ventilation. the entrance was quite dry in the apartment, that is , i still had to periodically open the windows and ... and at least somehow ventilate the room a little, because the breezers were not able to ventilate such a large room. sellers of breezers recommend installing them in every living room, and the exhaust hood must work well. some models can serve in recirculation mode without outside air intake, simply cleaning the air and heating it up if necessary. a real salvation, a breezer or... purifier can be for allergy sufferers. for example, in the family of ekaterina kunitskaya, everyone suffers from this problem. there is even a separate first aid kit for antihistamines. a few years ago, birch pollen triggered asthma in little varvara. my brain itches, i sneeze, cough, and my eyes, my eyes itch, my eyes

sometimes swell. mom fights allergens on all fronts, she vacuums seasonal things in a closet so they don't collect dust, and steams home textiles and soft toys. unfortunately, this doesn't always help. dust mites sometimes start up in it, well, yes, uh , dust. that's why i have to wash it, for me, a purifier is an indispensable thing now, because we open the windows, dust flies , we take out things, salt, dust flies, all this circulates in the air and this thing allows itself to collect all this and not let us breathe it. the purifiers pass the air through a system of filters, each of which performs its own task, for example, the carbon filter destroys odors, the heppa filter holds back... dust particles, and the photocatalytic filter kills bacteria, fungi and viruses. this technology, by the way, is used in space.

installations called flow, installations for photocatalysis of air, which just clean the station from various bacteria and fungi that can inevitably appear on any surface due to the life of astronauts there. the surface of such a filter is covered with a layer of titanium dioxide, a catalyst for a chemical reaction and, under the influence of ultraviolet light, it gnaws. manufacturers claim that these devices improve sleep, speed up metabolism, and kill bacteria, but this has not been scientifically proven. yes, the devices generate electricity, as in a thunderstorm, and some of the molecules pass into the state of charged particles, ions, but their health benefits have not been proven, and scientists from the alinoian institute of technology recently discovered that the ionizer actually replaces

some harmful substances to others. our permanent expert, ivan kalinin, also warns of the danger. during the operation of the ionizer device, there is a by-product. one of the most important is ozone, which is a very strong oxidizer, and because of which quite large health problems can arise. we recorded another effect of such a device during a colorful experiment: we filled two glass cubes with smoke, simulating dust, and placed an ionizer in one of the containers. as a result, the air here was cleared in less than 2 minutes, but is it good? the ionizer essentially knocks down dust, it makes its particles electrify, they stick to surfaces, walls, furniture.
