Previous page        Return to Catalog        Next page

    By the time they finished their simple dinner and Gao Wu cleared up the mess, the moon had already risen.

    Zhao Hao pointed the two-foot-long telescope in the direction of the moon and asked the two of them to look at it one after another.

    But this viewing experience is definitely not a pleasant one

    When the moon far away in the sky came to them.  The two clearly saw that there was no sea, no forest, and no sign of life on the entire moon.

    ??????????????????????????????????????????????????? away from the place where they originally thought it was the osmanthus tree, the toad palace, and the jade rabbit.

    The moon that they ideally imagined to be as bright and flawless as a silver plate turned out to have a big, numb and swollen face.

    "How could it be like this" Wang Wuyang and Hua Shuyang looked at each other dejectedly. They really couldn't accept that the Moon Palace, where countless beautiful legends were entrusted, was actually a dead and barren land

    Zhao Hao¡¯s previous experiments only aroused their interest in science, but now the observation of the moon directly challenges their worldview.

    "There's nothing surprising about this." Zhao Hao still said calmly: "The moon is just a planet with bumps and bumps like an orange. There is no Chang'e, Wu Gang, laurel trees, or even water and air on it."

    "Is the moon a planet?" The two of them were afraid of missing something and ignored the shock in their hearts. They quickly asked the teacher: "Master, what is a planet?"

    "A planet is a spherical celestial body that moves according to certain laws in the universe." Zhao Hao said solemnly: "The sun, moon, metal, wood, water, fire, Saturn and the earth are all planets."

    "If that's the case, why can we only see the full moon on the fifteenth day of every month?" Wang Wuyang asked puzzledly: "For example, today, the moon is obviously missing a piece!"

    "That's not right!" Hua Shuyang slapped his thigh when he heard this, and hurriedly observed again: "I just saw a black shadow in the missing part of the moon. If you include that black shadow, the moon tonight is still full.  of!"

    "It's true!" Wang Wuyang also leaned over to take a look, and he could clearly find that the overall outline of the moon was round, but part of it was blocked by something.

    "What is it covered by?" the two asked in unison.

    ¡°I¡¯ll demonstrate it and you¡¯ll know.¡± Zhao Hao said, holding a small white ball the size of a pigeon egg next to the lamp.  "Because the moon itself does not emit light, the so-called bright moon is just reflected sunlight."

    The two of them looked at the small ball that was reflected in orange and asked in a low voice: "It should always be a full moon."

    "Yes, but I just said that all planets are always moving according to certain laws." Zhao Hao said, and took out a big ball painted blue, blocking the small ball representing the moon and the candle representing the sun.  between.

    Then Zhao Hao slowly moved the small ball to rotate around the big ball, clearly demonstrating the waxing and waning changes of the moon to the two of them.

    "The so-called waxing and waning moon actually refers to how many places on the earth can be seen illuminated by sunlight. Because the moon revolves around the earth. On the first day of the lunar month, it is between the earth and the sun, and we can only see its backlight.  One side, so you can't see it with your eyes. On the seventh and eighth day of the lunar month, the moon moves to our side. At this time, we can clearly see that it is dark in the east and bright in the west. It is the so-called "first quarter moon".  '. On the fifteenth day, the moon goes around the back of the earth again. At this time, we can see its complete light-facing side, which is the day of the full moon"

    "I know!" Hua Shuyang suddenly realized: "Then it continues to rotate, and on the 18th or 9th, that is, today, it will be dark in the west and bright in the east, becoming a waning moon!"

    As he spoke, he clapped his hands, and Ying Wu said: "It will take exactly one month to complete the circle!"

    "You can be taught," Zhao Hao nodded in approval, then looked at Wang Wuyang and said, "He understands, what about you?"

    "I probably understand it, but I just follow what Master taught me" Wang Wuyang pointed at the blue ball in Zhao Hao's hand and said with a trembling voice: "Don't we also live on a ball?"

    "Yes, Master, isn't it that the sky is round and the earth is round?" Hua Shuyang also asked in disbelief.

    "Of course not." Zhao Hao took out the last teaching aid from the wooden box - a globe!

    He turned the blue sphere that resembled an armillary sphere, then pressed it gently and said to the two students: "This is the earth we live in. Three-quarters of it is covered by sea water, and the remaining quarter is land."

    The two students stared at the land masses marked with different colors on the blue globe, and soon saw the location where Ming Dynasty was written.

    "Is our Ming Dynasty here?" Hua Shuyang came closer and looked at it carefully: "The one next to him looks like a bug.Such a place, is Japan?  "

    "Ah, Fo Langji is here! There are so many countries separated from us. So the Thai and Western countries are so far away from us?" Wang Wuyang shouted from the other side: "It's really incredible that Fo Langji's sailboat can sail to the Ming Dynasty.  Simple!"

    "Yes, although I don't want to say this, I still have to admit that the countries in Europe and the West have gradually caught up with the Ming Dynasty, and even surpassed us in the fields of navigation, astronomy, mathematics and other fields." Zhao Hao sighed: "  For example, they were the first to discover and prove that the earth is round."

    "How did they prove it?" Hua Shuyang asked in shock.

    "A hundred years ago, the theory of a round earth had spread throughout the European and American countries, but there were always people who didn't believe it. So forty or fifty years ago, a French captain named Magellan decided to sail around the world.  Because if the earth is round, as long as he keeps sailing in one direction, sooner or later he will return to the starting point."

    Both of them understood this, but they just nodded slowly and said nothing.

    They were completely shocked by the feats of the great navigator.

    Zhao Hao spoke slowly to the two of them in a low voice: "In 1519 AD, which was the thirteenth year of Zhengde, Magellan, with the support of the King of Spain, led five ships and 270 sailors from Spain.  Port of Saint-Rocal and began the greatest expedition in human history!¡±

    As Zhao Hao spoke, he slowly drew lines on the earth with a brush: "They first crossed the Atlantic Ocean in seventy days and arrived at the coast of Brazil. Then they went south along the coast, bypassed South America, and entered the Pacific Ocean.  . After sailing on the Pacific for more than a hundred days, we arrived in Luzon."

    "Luzon?" This place name is familiar to both of them, and it has entered the traditional sphere of influence of the Ming Dynasty.

    "Then they crossed the Indian Ocean, arrived in Africa, rounded the Cape of Good Hope, went north along Africa, and finally returned to Spain" Zhao Hao expressed his respect for the pioneers in a deep voice: "At that time, they had only  There was only one remaining ship and eighteen sailors, and even Magellan himself had died midway.¡±

    "But they used the most indisputable method to prove that the earth is round!" Finally, Zhao Hao raised his voice, looked at the two people with piercing eyes and said: "This matter is already well known in the countries of Europe and the West, and you will definitely encounter it in the future.  If you go to Taixi, you will know the truth and lies just by asking.¡±
