Reflections on "One Hundred Thousand Why"
Recently, I read the book "One Hundred Thousand Whys", which is very rich in content, ranging from astronomy and geography to trivial things in life. Every article tells us a scientific truth. Among them, my favorite is Why Uranus is called a Cold Planet.
Among the nine planets, if Jupiter is called a "hot planet", then Uranus is a "cold planet". Although its distance from the sun is twice as close as Neptune, its surface temperature is the same as Neptune, not much higher than Pluto. According to the measurement of its radiant energy, only 6% of its radiant energy comes from the interior of the star, while Jupiter, Saturn and Neptune have 40%. It can be seen that Uranus is the only planet in the solar system that lacks internal heat energy. According to the current structural model of Uranus, its central temperature is only 2000 ℃ - 3000 ℃, far lower than other planets.
In addition, outside its core, there is a mantle with a thickness of about 10000 kilometers. What is different is that this mantle is composed of water ice, ammonia ice and methane ice. If we want to fundamentally say that tomorrow's Uranus is "cold", we must go back to its origin and evolution history. According to its high ice content, which accounts for 50% of the total mass, some people think that it is formed by the aggregation of numerous comets, which are cold "dirty snowballs".
The 100000 Whys not only helped me broaden my horizon and increase my knowledge, but also improved my reading interest, making me realize how colorful the world is. I like the 100000 Whys.
Why 100000
When I was young, I encountered problems that I didn't understand. I asked my parents why. But as I grew older, I gradually asked some questions, so I asked my sister to go to Xinhua Bookstore to buy me a set of "100000 Why".
Now, whenever I encounter a problem that I can't solve, I just need to open the book to solve it. This set of books deeply attracted me like a magnet. I found many common sense in life, which are all on it. Now, I like reading it more and more. Now, The 100000 Whys has become my mentor and friend, accompanying me every day. I don't need to ask my parents for advice when encountering problems that I don't know. The knowledge built up is much more useful than the memory garage of parents.
I remember one time when we had to learn the proverb, "Good medicine tastes bitter and is conducive to illness," I stopped. I didn't understand why this was the case, so I consulted the "little teacher", "100000 Why", and soon helped me find the answer. It turns out that although the medicine is bitter, it is still magical? My stomach disease is good to eat Chinese medicine. I'm not afraid of pain, because it can cure my disease. You think: taking medicine is better than injection! Therefore, we should read more books in the future, and we can find answers to questions we don't understand from extra-curricular books.
Ah! I learned a lot of knowledge at once by reading "100000 Why". Here, I am very grateful to my sister for buying me this good book. It is this book that makes my study so easy and happy.
I prefer the book "One Hundred Thousand Whys", which brings us learning convenience and some common sense, so I will read more books in the future to learn some knowledge.
