How about Dai Zongfu? Qi and Lu Qing are still alive.

The creation is full of gods, and the yin and yang are divided into darkness.

The clouds are growing in the chest, and the birds are coming back into the eyes.

You will be on the top of the mountain and overlook the small mountains.

——Du Fu's "Looking at the Mountain"

Unexpectedly, Du Fu was also very passionate when he was young.

Later, it was so sloppy that it was dependent on someone's roof, and the autumn wind was in the hut.

After going to Chengdu to attend the wedding of my roommate, I went to a park in Chengdu, which seemed to be Du Fu's Thousand Poetry Garden.

I took hundreds of his poems because not only the poems are good, but the calligraphy on them is also very good.

Star travel is the dream of mankind.

Scientific knowledge helps cultivate people's critical thinking.

One of the purposes of climbing a mountain is to look at the other side of the mountain.

I checked online and found that the 911 incident caused thousands of people to develop cancer.

Unexpectedly, the consequences were so serious.

Alas, it is almost 20th anniversary of the 9/11 incident, and the United States has also retreated from Afghanistan.

Coincidence? No. There is a certain relationship here.

The spring of the sophomore year at Harvard, Tyson took a lot of courses "hungry". One day, he chatted with a senior senior and mentioned what he did every day. He said: "I have to study a lot of questions every day.

There is almost no spare time, and I almost forgot to eat and sleep."

Yes, when I recalled the spring of my sophomore year, I almost forgot to eat and sleep and read books, study, and accumulate knowledge. I was so hungry that I was never satisfied and was determined to study.

I chatted with my mother in the morning and she said that when she was a child, she liked sweet potato buns the most. I said, why don’t you eat meat buns?

She said that at that time, the family was poor, with only vegetable buns and sweet potato buns. Moreover, in the village, basically every family was like this. Anyone who made pork could smell it far away.

Suddenly, the Greek letters were very interesting.

Ω, in cosmology, is the most commonly used symbol.

Ω represents the ratio of actual mass density to "critical" density in the universe.

It can tell us whether the ever-expanding universe will one day collapse again due to the accumulation of gravity of all the universe's material.

"Silently manipulate the engine of the entire universe through equations."

This sentence is so awesome.

There may be three reasons for the destruction of the earth:

"The demise of the sun, the collision between the Milky Way and Andromeda galaxy, the demise of the universe."

Galileo: “The Bible tells you how to go to heaven, but it won’t tell you how the sky works.”

"When I am at the forefront of universe exploration", "When I stand on the observatory on the top of the mountain to observe the endless night sky, my heart is filled with reverence for the magnificent universe."

"In the cycle of life, all matter and total energy are conserved."

The ending of "The Sky Without Border" is very well written, and the excerpts are as follows:

“When I die,

I hope to be buried,

Instead of cremation.

No matter at any time,

After the organic matter is cremated,

The biological energy contained in the four trillion cells,

Convert to heat energy completely

These heat energy will increase the temperature near the funeral home,

Finally radiates into space.

When this heat energy accumulates in the universe,

Low energy radiation increases the entropy of the universe.

And this process largely makes it impossible to recover.”

"This little heat is far from making up for everything I owe to the Earth (and the universe).

Throughout my life, I live by eating vegetation and animals on the earth.

Countless plants and animals sacrifice their lives,

Helplessly contribute their energy to maintain my survival.

All I can do is dedicate my body to this planet, the third closest to the sun.

I hope to be buried in the soil after death as I did in ancient times.

In this way, my body can be decomposed by microorganisms.

It acts as a nutrient for reptiles and rhizomes.

I will be their food,

It's like they used to be my food too.

At least I can return some of the energy I have taken from nature to all things in heaven, earth and earth."

After reading it, I remembered a sentence from the Bible:
