Why we see? And under what conditions? We see objects only because on them there are treatments of light and shade. In darkness everything is covered by absolute “shadow”, everything is black, and we do not see. However and at bright light we would also see nothing if shadows disappeared. Everything is dazzling would shine, would stick together eyes. And only. Sometimes inexperienced photographers seat photographed against a strong light source. Shadows almost disappear, and on a card instead of the person “pancake” turns out. Features cannot almost be distinguished. And light was more, than it is necessary! If we, as well as on the Moon, had no atmospheres, then all objects standing in a shadow absolutely would disappear from the field of our sight, and the subject lit half would seem to us the photo cut in two. Our sight is adapted for terrestrial conditions where thanks to the atmosphere we have an incalculable set of shadows and penumbras. Let’s take the human face lit sideways. We see this person. However actually we see a huge number of variously lit points – and not therefore only that points are lit unevenly, but also because the person unequally absorbs and reflects rays of light.
The beam which fell on black as if by soot the drawn eyebrow, it is almost entirely absorbed, and the pale cheek will reflect light completely. But also on this cheek there will be many separate points which will unequally reflect light. Each point of the person sends to our eye a separate beam, and beams these different force. Some points do not send beams also at all. All beams meet in our eye “lens” – a pupil, and then, having refracted, again disperse – exactly as in a camera lens! But display arises not on “an opaque plate”, and on an eye retina. The last consists of huge number of separate flasks, and each flask has “wire” – the nerve transferring the image to a brain. Look in a microscope approximately of a fly. There it is visible more distinctly. An eye of a fly is similar to honeycombs. It is not one, but hundreds of six-sided eyes. And on each of them only one beam – strong or weak gets. Our retina represents something like a board for a mosaic with ready dimples into which it is possible to insert stones of the first color. Set of these “multi-colored” rather raznosvetny stones also creates an overall picture, be this person or any other subject.
And the photo cell has no “retina”. The photo cell is only one flask of our retina, it is only one cell of an eye of a fly. If the fly could close all cells of the eye, except one, then either one light point, or an arithmetic average of all beams would get to this cell. And the fly would see only one spot. Here the same arithmetic average of all beams receives also a photo cell from the lit human face. Also it reflects only one spot.
But how in that case to transfer the image of the person? You will not remake a human eye, and a photo cell if on it all beams reflected by a human face fall can transfer only a light spot. It is impossible! But the separate points on a face which are sharply lit can be transferred. If to cover the lit face with the screen and in the screen to make a small hole which, say, passes a light beam only from one point of the person, then this beam, without mixing up with others, gets on a photo cell and causes the corresponding current which can be transferred and again to turn into light point. If we place this hole in the screen against brightly lit point on a nose, then the bright beam will cause also current of the corresponding force, so, and on the accepting screen brighter point will flash. If the hole appears against the shaded point of the person, then and it will be reflected in the screen more dark stain.
Thus, it is possible to transfer only separate “stones” of different coloring for our mosaic portrait. At the same time on our mosaic these “stones” will settle down in the same spatial ratio in what they were on a face. However how to make the finished mosaic portrait? We have an opportunity “to send” only one “stone” for once. Let’s say sent black – eyebrows – and it is necessary to send white “stone” – a forehead. But hardly we will move a screen hole from eyebrows on a forehead, black “stone” will disappear, and we will not receive a mosaic portrait. So it would also be if one feature of our sight did not come to the rescue. From the screen black “stone” disappears, but he still lives in our eye and some time keeps. Our sight is capable to keep what was seen during approximately seventh fraction of a second after the subject dropped out of sight. Thus, we will see still black “stone” on the screen when on it white appeared in other place. And not only these two. If in one seventh seconds we manage to send one by one hundreds and even thousands of “stones”, then on the screen we would see them at the same time everything. Needless to say that by what the smaller quantity of “stones” will be laid in our mosaic, that the portrait will “be more rough”. The task, leaves, in that for the shortest time it is possible to transfer more “stones” – light points. This task was solved by Nipkow’s disk. In this disk of a hole are placed on a spiral. Each point of the person sends a ray of light through a certain hole of a disk. And all points at the same time create full “portrait” – the image of the person who during transfer can even move, laugh, and all these movements will be repeated on the screen.
The problem of television was so solved.
However the decision nevertheless was incomplete. I already said that the more in our mosaic, the image is fuller and more expressive than “stones”. But we are limited to time. And if we give for a short time too many “stones”, then each of them will exist very short time. The more “stones”, the less time “burns” on the screen light point, the photo cell works more weakly, the less light is transferred to the screen, and the image appears dim. It was necessary to look for an exit in other design of a photo cell, and the right way of searches could be only one – to try to create the photo cell coming the device to a human eye with its “mosaic” of a photosensitive retina.
Such photo cell was also created. In it there is a transferring tube, on it a photosensitive mosaic on which the cathodic beam slides. Each element, each cell of this mosaic is as if a singular photo cell of the microscopic size like a flask of our eye. Each element receives a charge from a light beam. This charge is sent by the lamp amplifier. Each point of a new photo cell consists of the small silver ball covered with a caesium layer for photosensitivity. What did we reach? The image became expressive, clearer and lit. There was a possibility of increase in screens.
Whether the problem of ideal vision at distance is solved by it up to the end? It is clear, that does not decide. The wonderful eye of the TV still concedes to the most wonderful eye of the person. The task is in that on the TV screen we saw not worse, than on the screen of cinema. But also the cinema did not tell the last word yet. Why not to reach the color images which are ideally transferring nature why not to solve a problem of stereoscopy of the image? In a word, the screen of the TV is designed to give and will give ideal copies of reality. The image on the screen reaches full illusion. The person forgets that he sees the image on the flat screen, but not “an open window to the world”. The television connects to a sound broadcast. The person both sees and hears that he becomes in other place. The person creates to himself a teleeye and a teleear. Before it the whole world is open, and he becomes really the owner of the world. Its horizons extend to boundlessness. Its knowledge of the world increases. He becomes the new person in comparison with the ancestors – the person giant. Ancestors heard only at the distance available to an ear, and saw only with the naked eye.
Yes, the person will undergo wonderful transformation, will rise by the highest step, will gain “divine” properties of an omniscience and vseslyshaniye.
Eternal glory to that who worked on creation of these new tools of human knowledge of the world – “superears” and “a wonderful eye”!”
– Well? How? – Mischa asked, having finished reading.
Ginzburg moved lips.
– Anything, interestingly. You did not understand something, something is inexact lit. And in general it is interesting. About a cat tiger – it at you well left.
Mischa was a little disappointed. The cat is so, for humour, and here what scientific inaccuracies? But Ginzburg hurried.
– Reach! You will study more deeply, you will correct itself. Then you will read to me once again.
– But you go soon!
Ginzburg a broad gesture showed on the screen, a loud-speaker and theatrically recited:
– There is no separation any more. We will see and speak here is how now.
At last there came also day of departure of an expedition. Ginzburg warmly said goodbye to Mischa.
– Good-bye, and, I hope, to fast – he told. – You will see me on the screen as soon as I arrive to Murmansk and I will enter a radio cabin. On our trawler I will place TVs so that you will be able to see almost everything and by steamship, and around. We not for nothing worked with your father!
Mischa strong shook hands with Ginzburg, and they left.
The engineer Borin left to see off the guest.
When Mischa remained one, he looked at the white screen with the size in square meter, as on the page of the book where the text of the fascinating novel will appear soon.
MISCHA THE BARIN GOES TO THE TELEEXPEDITION
In the evening of the same day Mischa heard Ginzburg’s voice from a loud-speaker:
– Hallo, Mischa! I fly over Petrozavodsk. Over the Petrozavodsk airfield a beacon in two million candles. Bumpiness. Night flight over Karelia. Aero beacons specify the direction of flight… Just came back from salon restaurant. Ate tasty fish – a salmon. At supper – a concert from Madrid. I go to bed soon. Good night! In the morning, I hope, we will meet.
The voice ceased. The father entered.
– Who with you spoke? – he asked.
– Motya – Mischa answered and sighed.
This night he slept is disturbing. It dreamed flight over Karelia. The plane fell in dark. Bears ran together and began to jump near the broken car. Mischa drove away them the burning golovny. Then it flew again, and again the plane fell. Mischa bailed out and broke a leg. Leg of a zanyl. He moaned and woke up. Windows of an office were densely closed, the lamp shone, and it was impossible to define, morning now or night. The nurse came, washed Mischa and gave hot tea. There was ninth o’clock in the morning. Suddenly Mischa heard Ginzburg’s voice again:
– Hallo, Mischa! Turn off light.
Mischa forgot about tea and clicked the switch. The screen recovered. Ginzburg, smiling, stood on the deck of the trawler and nodded. For Ginzburg were seen the boat and near port – an arrow and the winch for a trawl raising. Mischa already knew that this winch will lift the underwater TV. Behind a board dark waters of Kola Bay were seen.
Ginzburg made a sign a hand, and the screen darkened. In a few minutes Mischa heard Ginzburg’s voice again:
– Microphones are not installed on the deck yet. You will see soon and will hear me. In an hour we will move to the sea.
So the screen of the TV turned for Mischa into the original fascinating novel. A lack of this book was that Mischa could not overturn the read pages. However Ginzburg consoled him in the fact that as soon as the trawler comes to the place, continuous transfer of everything will begin that will occur.
Pages turned over one by one. Mischa saw how Sergo took to the open sea and began to rock on gray-haired waves as high-speed Perseus caught up with the trawler “Sergo” and went forward… There passed shkher of Finland, the cape Nordkap, Lofoten Islands, coast of Norway, Sweden.
Days went behind days, and on the screen of the TV the new picture – the Leningrad port appeared. The big motor ship lifted anchors and went to swimming. All three ships had to meet in the Atlantic Ocean.
Nikolay Petrovich Borin established a two-way radio communication with all three steamships. Mischa could now several times in day speak with the friend Motya. Got acquainted with the captain Makovsky, still the young man, with swarty Azores who also went to a travel, and, at last, with the diver Protchev. Protchev interested Mischa. If the captain Makovsky had a typical face of the Englishman, then the shaved face of Protchev had obviously Mongolian lines. It could be taken for the Mongol or the Chinese. Once Mischa asked Protchev why he is similar to the Chinese, and that answered that he was born in Vladivostok. Mother his Mongol.
Protchev grew up on ocean coasts and since the childhood fell in love with diving business. Now it was the person of years under forty, very strong. The round head, a very broad breast, to Pomor widely placed legs, heavy fists. He called himself the diver on calling. Still the young man he “set up records” long stay under water without diving suit. Protchev already fell by a bottom of five Soviet seas and now with impatience expected when it is possible to look that he is created at the bottom of the Atlantic Ocean.
During swimming the screen lit up not really often. Mischa saw the deck of Perseus, the captain’s cabin of Sergo, a cabin of the big motor ship.
The ships headed for twenty degrees of the western longitude and thirty seven degrees of northern latitude – exactly here, on the great ocean way from Buenos Aires to London and Hamburg, “Leviathan” died. Moscow shone electric fires for a long time, and on the TV screen Makovsky’s face with the English profile was still filled in with the evening sun. And what tone! This golden light of the sun, an ocean blue, yellow with black strips of a pipe of the steamship, white shirts of seamen – what clearness! Yes, it is better, than on the screen of cinema.
Captains of three ships reported on Barkovsky. Weather favored to an expedition. The ocean was quiet. Mischa himself could observe a rhythmical kolykhaniye of a surface of the water, and sometimes it seemed to it that he inhales “aroma of the ocean”. But, perhaps, this aroma was brought by ep-ronovets Kirillov if only aroma of strong “kepsten” [57] could remind a sea smell.
Sometimes on the edge of the screen steamships with overseas flags were seen. Passed them on a great way between Europe and America much. The Soviet flotilla from three vessels could draw, of course, attention. But as the Soviet vessels often crossed at this time the ocean, a talk on a flotilla was carried on meanwhile only among teams of foreign vessels. Some more days, and a flotilla will come to the place.
IN ATLANTIC
Makovsky sat in a captain’s cabin, having inclined over the card.
– So – he told and put a pencil the end to a skreshcheniye of the twenty ninth degree of the western longitude and the thirty seventh northern latitude.
– Profits? – Azores asked, releasing dense puffs of the Manila cigar from a mouth.
– As if – the captain answered. – The place of death of “Leviathan” is designated quite precisely. We, probably, should probe a bottom on the square about a quarter of square mile, no more. It is necessary to report to the headquarters that we arrived to the place. – Makovsky gave a hand to phone.
– A billeting – Azores stopped it – I will pass in a radio cabin.
Mischa Borin re-read history of ice campaigns.
– Hallo! – he heard Azores’s voice. – Who is on duty in the headquarters?
Mischa jumped up on a bed. He could already sit, but did not allow go to him yet.
– Ya. Mischa. It you, Azores? What new? You arrived to the place?
– Yes. Tell about it by phone to the father and companion Barkovsky. The captain Makovsky waits for orders of the headquarters.
– Now! – Azores heard an uneasy voice of Mischa and grinned. Azores knew with what impatience the inquisitive teenager expected when the flotilla arrives to the place. While Mischa called by telephone to members of the headquarters, Azores came back to a cabin of the captain and told:
– One is not absolutely clear to me: you, Makovsky, say that the place of death of “Leviathan” is known quite precisely; depths of the Atlantic Ocean are precisely known too why our scientists and technicians, designing the underwater TV, counted on depth about one thousand meters? Perhaps, such depth is also not necessary.
– Yes. Depths of the Atlantic Ocean are rather known – Makovsky answered. – Measurements of ocean depths established existence of the greatest underwater plateau which begins to the south of the British Isles, lasts on the West along the African coast and at an angle approaches South America. However this underwater plateau not flat. In 1898 laid the cable line from Europe to North America. For nine hundred kilometers to the north from the Azores the cable broke and fell to a bottom. To lift the end, it was necessary to look for several days it on a bottom steel cats. And that’s when it became clear that the bottom in this place reminded a mountain chain: everywhere high rocky tops, steep slopes, gorges, deep valleys met. Sami Azorskiye and the Canary Islands – only tops of these underwater mountains. The sunk “Leviathan” could lay down on top of the underwater mountain, and then to us, perhaps, it will be possible to lower to him even the diver. But it could dive also into the deep gorge, and into the underwater valley. Then who knows whether we will be able to lower even the television transmitter. Should we redesign it counting upon a deep water, so, and bigger pressure. We are over very uneven underwater relief now. Calculations were conducted on average depths of these places.
– What we will begin with? – Azores asked.
– As the headquarters will order – the captain answered. – I think, from a measurement of depths.
Makovsky was not mistaken. The headquarters ordered to begin careful measurements of depths on the radius of five hundred meters from that point where died as assumed, “Leviathan”.
“The reconnoitered circle” as it was called on the card, was divided into three sectors. In each of them one of expedition steamships had to conduct works. All data were marked on the map of big scale and broadcast to the headquarters.
For Mischa interesting days and hours came: it also got the card and designated on it depths, character of soil and so forth. Soon the piece of a bottom of the Atlantic Ocean became known to it, probably, better, than topography of streets of Moscow. What it was the marvelous underwater country! Around death of “Leviathan” from a bottom of the sea the mountain peak which hollow fell by the southwest rose. In the northwest there passed the deepest gorge of one thousand four hundred meters in depth. Now all question was in where “Leviathan” fell.
But the most interesting was ahead. People will lower “an underwater eye” in ocean depth, and Mischa will see hiding places of the underwater world. Oh, as slowly there is time!
Sergo, Perseus and Martie worked several days until finished measurements.
The radio communication worked almost continuously. The difficult question was considered: how to give to steamships perhaps big stability in the open ocean. The extended anchor chains hardly reached tops of the underwater mountain. One steamship still could drop an anchor, but for three over peak there was no place. Waves and wind could lead to collision of steamships and accident. And “Leviathan” could lie on a considerable distance from underwater peak. The floating anchor only slowed down drift of the steamships carried by a sea current and wind. Meanwhile almost full immovability of vessels was necessary for work with a TV eye. It was necessary to lower a teleeye on the bottom, and it extremely uneven. The device will trudge on a bottom and can crash against ledges of sharp rocks. It was necessary to hold cars under steam and to maneuver the screw.
– And unless it is impossible to extend an anchor chain? – Azores asked.
– Of course, it is possible – Makovsky answered. – But you represent what weight of a one and a half kilometer long chain will be?
– Means, it is impossible?
– Up to the certain depth it is possible. For big depths we should build special steamships, special winches, arrows, special decks or pontoon bridges for folding of a chain. Depth is a stronghold which is not so easy for overcoming.
At that time when steamships prepared for descent of a teleeye, in Moscow, at institute of telemechanics, three new offices of underwater television were prepared. With the first there could be an accident. Besides and searches will be quicker conducted if each steamship has the TV. TVs will be delivered to the ships gidrostratoplany which creation is just finished by the new plant of jet superhigh-rise transport.
