Popular Science Reading Notes.

This summer, I read the book "100,000 Whys in Space", and I learned a lot of scientific knowledge from it. For example, the largest celestial body in the solar system is a comet, commonly known as a sweep? Star, which is composed of a Hui head and a Hui tail, where the Hui head is composed of a Hui core and a Hui hair.

The diameter of the comet's nucleus is about 10 kilometers, and the huge air mass around him is Huifa, which has a diameter of tens of thousands to hundreds of thousands of kilometers. Huiwei is even longer, reaching hundreds of millions of kilometers.

I also know why the sun shines? This is because the Sun is a star, the largest celestial body in the solar system, and this large gas balloon releases a lot of light and heat all the time. It is precisely because of the sun that the earth has warmth and light, and there is life.

The temperature on the surface of the Sun is about 6,000 degrees Celsius, and the temperature at the center is also 15 million degrees Celsius. This is due to the violent atomic reactions that take place inside the sun. The sun is made up of more than 70 elements, the main component of which is hydrogen.

The temperature and pressure inside the sun is high, and this is where the nuclei of the love atoms interact, thus releasing a lot of light and heat.

I also learned that Mars is also one of the eight planets in the solar system, and scientists call him Earth's "twin brother". This is because Mars has many features similar to Earth.

If you look through a telescope, you'll see that Mars is simply a "globe". Its poles are white polar crowns, like the snow-covered north and south poles of the earth. And Mars also orbits the sun at an angle like the Earth.

In addition, a day on Mars is 39 minutes and 35 seconds longer than a day on Earth. The difference is that a year on Mars is 687 days, which is twice as long as a year on Earth. Like Earth, there is an atmosphere on Mars.

The universe is amazing, when I grow up, I must be a scientist to study the mysteries of Mars, will humans be able to live on Mars in the future? Please trust me, I will definitely study hard!

After carefully reading a famous book, you must have a lot of things to share, write a review after reading, and record the gains and contributions. But how to write the feeling after reading? The following is my review of reading popular science books for you, welcome to share.

I took out a copy of "The World of Juvenile Science Popularization" with the fragrance of ink and flipped through it. Oh, how knowledgeable an article is! Gorky said:"Books are the ladder of human progress. "Oh, yes! A good book will benefit us a lot.

The content of "Juvenile Science World" is very rich, including astronomy, geography, biology, human body, health, animals, medicine and other aspects, and it is a popular science book to increase knowledge. The plain text in the book, fresh and natural; Humorous narration ......What a bizarre and interesting story! "Juvenile Science World" made me feel childish, and those specific and detailed words made me feel the existence of scientific mysteries from time to time.

After reading this book, I have broadened my horizons, I know what to pay attention to in my daily life, and I have learned a lot of scientific truths. The novel knowledge in the book made me feel the colorful world and the ever-changing nature world, which really made me love it.

One of the things that interests me the most is the article "There are more and more remote controls at home". "There are all kinds of remote controls, strange shapes, and in recent years, the number of remote controls at home has increased relatively quickly. There are too many remote controls, and it is very inconvenient to use, and people have invented multi-function remote controls.

This passage reminds me that as my family's living standards have slowly improved in recent years, there will be more and more electrical appliances at home.

Books are a source of knowledge. It can teach us a lot. A good book can not only stimulate learning.

Fountainhead. A good book can not only stimulate the desire to learn, but also broaden our horizons, it is an invisible teacher, helping us to walk on the road of life.
