The universe is sounding and trembling – Kookmin Ilbo

This anecdote appears in Cosmic Connections, the first book of mass science published by astronomer Carl Sagan (1934-1996). He went to dinner with a design publisher and a Polynesian restaurant in Boston, USA. "You will be prompted to decipher important messages soon." Could it be a coincidence? In fact, he became a Belgian salesman of Cosmic Connection and his successor, Cosmos, became a long-term astronomical bridge linking Earth and space. People love him most.

However, the person who received the "request to decrypt the important message" would not be the only one. Many scientists who shine like stars around the world are still struggling to measure the order of the universe or to inform people about the series.

Kim Sang-wook (48) can not be ignored if one of those who plays such a role in Korea is mentioned. He is a professor of physics at the University of Kyunghee and recently became a home designer in the TV program "Alleyshin 3" (TVN). "Tremble and Reverberation" is a beautiful and lively public science book he published.

"The universe shakes"

Let's start talking about the title. Why did he mention the words "trembling" and "echo"? The reason is that these two keywords can explain the mechanism of the universe.

The writer says, "The universe is shaking, all the postures tremble." The problem is that it is not literary research. The table in front of you and books in the library are also in the Jeongkungdong movement. Observation by electron microscopy can give a small vibration to everything.

When the vibration is high, it becomes a wave. The wave makes the world. All waves and sounds are waves. Why, then, the word & # 39; eolim & # 39; next to the title?

"People are reacting, we are dealing with a lot of terror in the environment … We want to be a person who responds to others' horror, my echoes are another freshness and I want to be rewarded with a new echo, people repeat and tremble.

In "trembling and echo", such a beautiful and beautiful phrase easily leads. The writer uses two keywords that tremble and repeat, like weft and isolation, drawing a huge class for the universe.

It is a work that can feel the spiritual pleasure if everyone believes it is difficult but does not have many contents. It is thanks to the ability of writers to highlight complex content in literary style. The author wrote: "I wrote in the hope that physics would look human," and wrote: "I tried to say physics through the sense of the humanities." This objective appears to have been achieved steadily. It is rigid and quite specific that it does not matter if a scientist writes any questions or not.

The stories in the book are not really playful. Scientifically, he examined in detail any kind of Gotham theory that the famous thinkers of the East and the West would refer to. "What time is it?" "How long is the space?" "Death is something," "How does the world work?"

Among these questions, the look of the natural for death is very different from that of ordinary people. "When we know the person, everything in the world is starting to look different," he writes. Everything that stands out is just a "gathering of people," so death is just a scatter of people. "A person is immortal, so the birth and death of a person is no different than the concentration and dispersion of individuals."

It is also impressive that the reason why there is the world. To explain why the world exists, we need to explain the beginning of the universe. Physicists believe there is a "starting point" of the universe, which is the big bang. However, this does not mean that the universe was born while "beating" the place. Before the Big Bang, there was no empty space. Why is the Big Bang theory convincing? This is the observation that the universe is expanding steadily. This result can be achieved by identifying the path of light coming from the past. To answer the question "Why is there people?", You need to explain why the big bang happened. The author completes the story of this issue by introducing a phrase in the masterpiece of Stephen Hawking (1942-2018), "The History of Time."

"If we find the answer to the question of why the universe exists, it will be the final victory of human logic, only then we will know the heart of God."

The world of science

Let us remember the remarks of Albert Einstein (1879-1955). "God does not play backgammon." The very essence of this statement is that they all have a set of principles. If so, is there a "decisive future"? The problem is chaos. There are complex moves in the world that are difficult to predict. If so, is there no answer that can be enjoyed by human beings? Science is ultimately a study of agnosticism.

In conclusion, we have a mathematical weapon. Science is "dominated by the rule of probability". If you throw away a & # 39; 1 & # 39; when you throw a dying, you can not understand why this number came out, but you can see the possibility of a "1". We can solve many difficulties with a simple add / drop system.

"Mathematics describes nature in an incredibly accurate and effective way … The physicist believes that even if he meets an alien, he can communicate in mathematics, I do not know if the universe is actually used in mathematics or if we can only understand it in terms of mathematics, but without mathematics there is no physical. "

The universe moves according to the formula. One day is 24 hours. One year is 365 days. If you drop something on the ground, it drops 4.9 m per second. But there is no special reason for the appearance of "24" & # 39; 365 & # 39; & Quot; 4.9 & quot ;. The same applies to other scientific laws. However, human beings deliver the concept of something to the back of science. We believe that people have appeared in this world, the disappearance of dinosaurs and the exchange of love.

The writer wrote: "Human beings make sense to the pointless universe and live." "Although the meaning is only a product of imagination, it is human to live like that, I do not know what happiness is, but it is people who try to live happily." Man happily enjoys the useless universe, enjoying the imagination he made in his fantasy system. So the human being is more wonderful than the universe. "The white paper of this book is that it draws the world of science away from being so cold.
