The light stream stopped also unexpectedly, as well as began. And at once after this event began to flow upside-down. All scales began to decrease. Harichkin and Larichkin’s “planet” contracted in the eyes, becoming less. It did not fly around a huge proton on an orbit any more, and approached it on a spiral. Also the proton decreased. “Solar systems” approached until merged in one molecule. Fussy molecules grew and approached one another. Here all of them united and became similar to the huge valley with mountain folds. Mountains were quickly narrowed as if thawed, and Harichkin and Larichkin saw soon that they stand on a caesium plate near big as the tank, inkwells.
On it their adventures did not terminate. Got closer to them, gleaming, a convex surface. It was the magnifying glass of professor Filinov. But also through a magnifying glass the old scientist could not make out the pupils yet. It was necessary “to breed” them a little. Then Eagle owls were taken by thin tweezers, picked up Harichkin and Larichkin and threw them into emptiness. Probably, it reduced again them because Harichkin and Larichkin long flew in world space before fell to mountain top. No, they did not break. They were easier than fuzzes. Rose, looked round around. This time they came to be in the new world.
“Earth” on which they stayed was not limited to the horizon. Regions of “earth” of hollow rose up and passed into “the heavenly sphere” of the same color, as “earth”.
– Whether there are no we in the world of the fourth measurement? – Harichkin asked.
– What there fourth measurement! – Larichkin objected. – Just we stand on the internal surface of a spherical body. You look, in the center of this sphere there is a huge ring strengthened on the core thrust to “earth”, and in “sky” opposite to us, some star foggy flickers. It occupies nearly a quarter of all sky.
– Listen! – Larichkin exclaimed. – Yes same middle of a glass cylinder of a photo cell! I knocked over a layer of “earth”, and something began to shine. It is, apparently, a silver layer. The caesium layer is applied on it. Therefore, we stand on the photo cell cathode, and a ring in the middle of our “Universe” – the anode. A round opening in a lamp as the giant window to other world, shines foggy: the photo cell, obviously, is already included in the battery, however streams of current and light are still small and the photo cell does not work.
– We, apparently, again decreased – Harichkin told.
– You see how “mountains” on our “earth” increased, and in the sky we see what was not noticed earlier again – countless multitudes of “celestial bodies” which move in all directions. These are not motes any more, these are gas molecules.
– Interestingly to travel on such planet – Larichkin dreams. – The small planetka – a gas molecule – approaches the surface of “earth”. It flies with the greatest speed, but it seems to travelers that it moves smoothly – they are microscopic beings.
– We jump! Hop! It is ready!. – Harichkin and Larichkin depart to space.
– The interplanetary travel began – Larichkin says. – Well and dance around us! To present only that the whole world stays in such continuous movement! Nothing does not stand still, “even the fact that it costs”. In a gravestone and in the gloomy rock, in a penknife and in the sunk anchor unruly are trampled down, fuss, molecules jump. In solid bodies – more smoothly, in gaseous – quicker, and the temperature is higher, the dance is more live.
Larichkin and Harichkin cross “interplanetary space” here and there. Their molecule with unprecedented speed falls down, flies up, hits against “sky”, then – again down, aside, faces other “planetka” sharply jumps aside from it – keep, do not fall!
During this wandering travelers had an opportunity to study “celestial bodies” from within. One molecules bore on themselves positive charges of electricity, others – negative, and many had both that and others. It were “neutral” molecules of gas.
Unexpectedly huge window occupying nearly a quarter of the sphere it is dazzling flashed. Now it seemed to similar to the real sun. This is Filinov sent a ray of light to a photo cell opening. The mass of light escaped from an opening, rushed through “an interplanetary scope” and began to fall meteorites on an opposite wall. Here also amusing began.
Fiery bombs fell to valleys and mountains, and over valleys and mountains anxiously began to fuss as if expecting a trouble, electrons. Light shells began to knock out these electrons – to tear off them from a surface, and electrons departed to an interplanetary scope, on the central ring – the anode. On the road they faced “neutral” gas molecules and knocked out from them electrons.
The stream of these electrons went to the center of the Universe – to a ring. It was also current. The photo cell began to work. The enormous interplanetary scope dividing the anode and the cathode was won. Under the influence of abyss light as if would disappear. Electrons – negatively loaded parts of electricity – flew to a positive pole.
But on it business did not come to an end. “Neutral” planetka – gas molecules – having lost an electron, became “a positive ion”. Such molecule has already only one satellite – a positive charge. The “earth” of caesium loaded with negative electricity began to attract it uncontrollably. And positive ions began to fall to “ground”. It was possible to think that there was a space disaster. The rain of positive electrons fell to “ground”, beat out new and new electrons each time. They soared up from a surface, rushed in an interplanetary scope on the central ring and fell. Other of them faced on the way neutral molecules, knocked out from them electrons which immediately fell to “ground”. And the stream of “meteorites” which broke from “earth” and flew to “the center of the Universe” grew as an avalanche – there was what is called increase in current.
Filinov, probably, still increased tension in a current chain to which the photo cell was attached, and gas molecules were suddenly lit. Now each of them became similar to the moon, and everything together they represented extremely beautiful show – thousands, millions of the moon which incessantly move.
– Gas luminescence? – Larichkin who did not forget about “terrestrial” names of the phenomena made in this world exclaimed. The sun window inflamed, grew dull. Filinov regulated luminous intensity. And when “window” shone stronger, the stream of electrons from a surface to the center of a sphere increased if “window” grew dull, also the current of electrons decreased – in other words, current fell. Harichkin and Larichkin saw what the scientist determines only by imagination, calculations given devices for observation own eyes. They could observe how the slightest increase or reduction of light increased or reduced quantity of the electrons falling on the central ring – that is current.
Harichkin and Larichkin were fascinated by an unprecedented show. They even forgot about danger and suddenly with horror saw that on their planetku-molecule the celestial body falls. They did not manage to scream from a fright as there was a collision and they fainted. And when recovered, saw that lie on a sofa near a cat of professor Filinov who had the usual sizes, as well as all around.
– There now – said Eagle owls – you also visited the world of a microcosm and now, probably, acquired much better all processes what are made in a photo cell. Light can give rise to electric current – you knew it earlier. Now you saw how he is born.
Photo cell! This new mighty weapon of the person. The current which is given rise or strengthened by light can set the mechanism in motion. Light can open and close doors, warn about the fires, stop trains, cars, to set huge cars in motion. Light of the star located at distance of hundreds of millions of kilometers from Earth can include an electric lighting, perform any task; the photo cell can sort cigars and consider development on the conveyor; the photo
