Chapter 29 Chapter 5 A Severe Exam

For those who spent months brooding over hypotheses to explain the mysteries of the universe, it all became clear.All doubts were cleared.Because of the collision between the earth and the comet, they were brought to the comet, and followed the comet to travel in the interstellar space.The large orb that Servadac had seen that night after the collision, hiding behind the clouds and soon disappearing, now appeared to be the Earth.The sea of ​​Galia was rough and white-capped at that time, which was also caused by the gravitational pull of the earth. A return to Earth is now at last hopeful, at least according to Professor Rosset.However, is his calculation so accurate and so foolproof?Everyone is still a little skeptical about this, which is completely understandable.

In the next few days, everyone enthusiastically helped the new guests settle here.Fortunately, Professor Seth is not very picky about daily life, no matter what arrangement is given to him, he can make do with it.He is with the stars all day long.He spared no opportunity to pursue a celestial body cruising in space, except for coffee, he seldom considered the issues of accommodation and food.He didn't notice at all that these developers used their talents on this desolate planet to arrange the caves of "Warm Land" in such an orderly manner.less than.The sky is always so peaceful, the sun is shining during the day, and the stars are shining at night, but the sun shining on the body is not necessarily much warmer than the stars.

However, this extreme cold, even outdoors, is not unbearable.Those who spend the winter at the poles of the earth fear nothing more than biting winds, suffocating fog, and terrifying blizzards.Many navigators who explored the polar regions often died because of this.But if there is no wind, even in Melville and Parry, and Karna, north of latitude 81°, farther than the intrepid explorer Harry sailed the Polar, no matter how cold it is, people only need to wear more clothes. Order some clothes, it's still tolerable. Therefore, the conditions for these developers living in the "warm land" are very favorable, and they can completely withstand the severe cold of space.Fortunately, there are many furs on the Dobrina, and they can often wear these furs to go outdoors.

Captain Selvadak is very concerned about everyone's health.He prescribed some beneficial physical activities for everyone.Everyone has to participate in these activities, and no excuses are allowed to escape, even Pablo and little Nina are no exception.Two lively and cute little guys, wrapped in bloated leather clothes, appeared on the ice rink by the sea, looking just like two Eskimos. What was Isaac Hackhabt doing now? He got frustrated in front of Palmier Rosette, very angry in his heart, and returned to the Hansa unhappy.However, his stubborn mind was finally loosened.Professor Rosset spoke in such a simple way that he could no longer disbelieve what everyone said a few days ago.He knew that he was now on a comet, thousands of miles away from the earth, and he could only resign himself to fate if he wanted to go back.

Captain Servadac was going to give up the best room to his teacher.But Rosette was determined not to, he did not want to live with everyone.He wanted a better, secluded room that could be used as an observatory, where he could quietly conduct his observations. Captain Servadac and Second Officer Prokop looked everywhere.It was a wish fulfilled, and later on, a small cave was found on a hillside more than 30 meters away from the big cave.Although the cave is small, it is enough for him to stay and conduct research work.A bed, a wardrobe and several tables and chairs can be placed in the hole.In addition, his astronomical telescope, which never leaves his body, can also be installed here.Captain Servadac also deliberately drew a trickle from the lava "waterfall" to keep him warm.

In this way, Professor Rosset lived here, and someone brought him water and food at a fixed time every day.He sleeps very little, calculates at his desk during the day, and observes the stars under the telescope at night.In short, he seldom bothered about everyone's affairs, and lived a completely reclusive life.Everyone knows his temper very well, so they don't bother him. The weather is getting colder and the temperature gauge has dropped to -30°C.The temperature in Galia is not like that on the earth, which fluctuates greatly and changes rapidly. Instead, it drops gradually and slowly, until it reaches the limit of the temperature in space, and then gradually decreases as Galia approaches the sun. pick up.

The main reason for the lack of fluctuation in temperature is the lack of wind.The climatic conditions in which the developers of Gallia lived were very special: the air was absolutely still and motionless.In addition, the running water on the surface of the comet has all condensed, so there is no continuous drizzle, and there is no violent storm. The sky is clear all day long, and there is not even a trace of cloud.The wet or dry mists that float around the poles of the earth all day long are here to stay. As the thirty-sixth resident of Planet Galia, it stands to reason that under the current circumstances, he should reflect deeply and make amends.Selvadak and others are God's intentions to stay by his side, and he should cooperate closely with them from now on, sharing weal and woe, and no longer regard them as objects that can be exploited.

He didn't do this, otherwise, he would not be a typical example of greed and profit-seeking in human society.On the contrary, he became more stubborn, bent on taking advantage of this once-in-a-lifetime opportunity to make a fortune.He thought that Servadac was extremely kind and would never do anything to harm him.Therefore, he was very assured of Selvadak that unless something unexpected happened, no one would embezzle his goods. He thought that although the hope of returning to Earth was very slim, it was not absolutely impossible.He can make great use of this opportunity.These Galians had gold and silver coins in abundance.Rare things are more expensive.His goods can be sold here today for a premium over Earth.He planned to take this opportunity to get the money from them bit by bit.But don't act too hastily, you have to wait until they are in urgent need of these goods before they can be sold at a good price.In short.It was these dirty ideas that he had been thinking about all day aboard the Hansa.

During April, Gallia covered another 156 million kilometers.By the end of the month, it will be 440 million kilometers from the sun.Its elliptical orbit, including its entire ephemeris, has been accurately mapped out by Professor Rosset.The entire orbit is divided into twenty-four intervals, and each interval represents the distance Gallia has traveled.According to one of Kepler's three laws, the arc lengths of the first twelve intervals from perihelion to aphelion gradually change from large to small; after aphelion, the arc lengths of each interval gradually change from small to large. Until the nearest point.

On May 12, Professor Rosset showed the chart to Captain Selvadak, Earl Iron Mashov and Second Officer Prokop.Everyone looked at the chart with great interest for a long time.They saw that Galia's orbit stretched out into space beyond the orbit of Jupiter.Gallia's monthly distance and distance from the sun are clearly written on a chart in numbers.If Professor Rosset's calculation is correct, and if Galia's revolution period is indeed two years, then two years later, Galia may rendezvous with the earth at the same place.But will there be a collision then?What are the consequences of a collision?No one wants to think about these questions.

At the same time, in view of Professor Rosset's eccentric temper, even if someone has any doubts about the accuracy of his charts, they cannot express it in the slightest. "So," said Captain Servadac, "Gallia covered only 136,000,000 kilometers in May, and is 550,600,000 kilometers from the sun?" "Exactly," said Professor Rosset. "Have we left the asteroid field now?" Count Iron Mashev asked. "You can see for yourself, sir. It's very clearly drawn on the diagram," said Professor Rosset. "So the comet will reach aphelion exactly one year after passing its perihelion?" asked Servadak. "yes." "That's January 15th." "Of course, January 15th... No, why is it January 15th, Captain?" Professor Rosset asked. "Because from January 15th of this year to January 15th of next year, it happens to be a year, that is, twelve months." "The twelve months you speak of are the Earth's calendar, not the Galian calendar." Prokop's second officer couldn't help smiling when he heard this. "Why are you laughing, sir?" Palman said.Rosette asked him. "I see that you want to revise the Earth's calendar, Mr. Professor." "I don't think so at all, sir, I just think it's more reasonable." "Okay! Whatever makes sense, let's do it!" Selvadak shouted. "Do you admit," asked Professor Seth, "that it takes two full years for Gallia to return to its perihelion after passing its solar point?" "Full admission." "Is the two-year revolution period the year of Gallia?" "certainly." "Should the year in Gallia be divided into twelve months?" "Of course, if you like, my dear teacher." "It's not a question of whether I want to..." "Well, divide it into twelve months," said Servadac. "Then how many days should each month be?" "Sixty days, because Gallia's day has been cut in half." "Captain Servadac," Professor Rosset said sharply, "Think about it carefully, is it right..." "I think I've accepted your point of view," said Servadak. "No." "I don't understand where is the problem river?" "The question is simple." Professor Rosset shrugged dismissively, "Should one month in Gallia be equal to two months on Earth?" "Of course. Because one Galian year is two Earth years." "Is two months on earth equal to sixty days?" "yes." "Two months on earth are sixty days, but to Gallia they are one hundred and twenty, because Gallia's day is only twelve hours. Do you understand?" "Understood, sir." Count Ironmashev said, "But this timing may easily cause confusion..." "There will be no confusion," said Professor Rosset. "That's how I've kept my time since January 1." "In this way, there are one hundred and twenty days in a month now?" Selvadak said. "What's wrong with that?" "There is nothing wrong, dear teacher. Then it is not May but March." "Yes, gentlemen. Today would be the twelfth of March in the Gallian calendar. And if sixty days later..." "That's March 72. Well, that makes sense!" cried Servadak. It seemed to Palmillan Rosette that his former pupil was laughing at him for being too complicated.But it was getting late, and the three visitors got up to take their leave. Professor Rosset compiled a calendar for Gallia.It should be said that this set of calendars is only used by him.Others stick to Earth's calendar as usual.For when Professor Rosset speaks of April 47th, or May 118th, no one knows which day he is speaking of. At this time, the sixth month of the old calendar has come, and this month Gallia has traveled even less, only 110 million kilometers, and 620 million kilometers away from the sun.Temperatures continue to drop and the weather is consistently good.Life in Gallia has always been orderly; very peaceful.But as long as there is Professor Rosset, who is eccentric and prone to anger, this peaceful atmosphere can be easily broken.Whenever he walked out of his observation room and came into the hall, there would always be quite a disturbance. Their debates, almost without exception, revolve around the question of the comet's next collision with Earth.Selvadak and others feel that although the collision is very dangerous, they can take this opportunity to return to Earth, so they still hope that the collision will happen.Professor Rosset was very angry. He didn't want to hear everyone talking about going back.He has been working tirelessly on his research, and it seems that he has no intention of going back. One day, June 27, Palmillian Rosette suddenly burst into the hall like a gust of wind.Captain Servadak, Second Officer Prokop, Count Ironmashev and Ben-Zov are all here. "Second Officer Prokop," he called, "I'm going to give you a question, and you must answer me immediately." "I'm afraid I can't answer well..." Second Officer Prokop said. "It doesn't matter!" said Rosset, in a tone that completely regarded the second officer as a schoolboy, "you answer me now: Have you ever sailed around the equator of Gallia in the Dobrina?" "Yes, sir, we have made round voyages," replied Prokop. "The Na's voyage is recorded." "We only made rough notes with our odometer and compass," said Prokop, "because we can't tell from the position of the sun or the stars." "What was the result?..." "The circumference of Gallia is 2,323 kilometers, which means that its diameter is 740 kilometers." "That's right..." Professor Rockit said to himself, "The diameter of Galilee is only one-seventeenth that of the earth, because the diameter of the earth is twelve thousand seven hundred and ninety-two kilometers." Everyone looked at Rosset, not knowing what he was going to do. "Gentlemen," Professor Rosset seemed to have guessed everyone's thoughts, and continued, "Due to work, I now need to know the area, volume, mass, density and surface gravity of Gallia." "Since we already know Gallia's diameter, its area and volume are not difficult to calculate." Prokop's second officer said. "Did I say that this problem is not easy to solve?" The professor growled, "Student Servadak, take a pen and do the math. The perimeter is already known, what should the area be?" "Master," replied Servadac with the care of a schoolboy, "multiply the diameter by the circumference." "That's right, the final calculation!" said Mrs. Rosset. "What is the result? Haven't you figured it out yet?" "The result is 1,719,020 square kilometers," said Selvadak. 255 damage, he said angrily. But Prokop's second officer still did not show weakness, and said bluntly: "Looking at Gallia from the earth, this planet is only a seventh-magnitude star, so it is completely invisible to the naked eye." Professor Rosset was about to have a fit, but he restrained himself. Just as Ben-Zoff loved his hometown—Montmartre, he also had a special affection for the comet he discovered, and he did not want anyone to despise it. Of. He finally calmed down and said to Selvadak and the others: "Gentlemen, we now know Gallia's diameter, circumference, area, and volume. These are impressive figures. But that's not all. I want to work out its mass, density, and surface gravity." "It's not that easy," said Count Ironmashev. "It's no big deal. I've got to work out the weight of my comet." "The problem is we don't know what Gallia is made of," Prokop said. "You really don't know?" Professor Rosset asked. really do not know. said Count Ironmashev, "if you know, please tell us..." "I'm going to figure it out anyway, even without knowing it," said Professor Rosset. "As long as you want, we will follow your orders at any time." Captain Selvadak said at this time. "I need a month to solve these problems." Professor Rosset said, "I think you will be willing to wait..." "Where is it, Mr. Professor?" said Count Ironmashev. "How long shall we wait?" "Yes, Gallia's area is equal to one-two hundred and ninety-eighth of the earth." Professor Rosset said. "What is its volume?" "Size?..." Selvadak was a little flustered for a while. "The area is already known, how should the volume be calculated? Have you forgotten?" "No, Mrs. Rosset...you push me so hard that I can't even breathe." "That's what it takes to be a scholar, sir." Selvadak and the others are very serious, otherwise Professor Rosedai would have been furious. "Have you figured it out? What's the volume?" "The same area..." Selvadak replied in a panic. "Multiply by a third of the radius, sir!" cried Rosette. "Have you not figured it out yet?" "Come on. One-third of the radius is 123 kilometers... The result should be 211,439,460 cubic kilometers." "This is the volume of my comet." Professor Rosset said, "This is not a small number!" "Of course," said Second Officer Prokop, "but it's only one-fifty-one-sixty-seventh that of the earth, because the volume of the earth is..." "1082.841 million cubic kilometers." Professor Rosset blurted out. "Gallia is much smaller than the moon," said Prokop, "for the moon is one-forty-ninth the size of the earth!" "Who told you this?" Professor Rosset's self-esteem seemed to be greatly stimulated, "As long as you want." "Then we will get together again on April 62 to resolve these issues," said Palmilla Rosset.He was referring to July 31 in the old calendar.
