This anecdote appeared in Cosmic Connections, the first mass science book published by astronomer Carl Sagan (1934-1996). He went to dinner with a publishing planner and Polynesian restaurant in Boston, USA. "You will immediately be asked to outline important messages." Could it be a coincidence? In fact, it became the best-selling book for Cosmic Connection, and its successor, the Cosmos, became a long-established astronomical bridge, connecting Earth and space. People love him more.
However, people who receive "requests to elaborate on important messages" will not be the only ones. Many scientists who shine like stars all over the world are still struggling to measure the order of the universe or to tell people about orders.
Kim Sang-wook (48) cannot be ignored if one of those who plays that role in Korea is quoted. He is a professor of physics at Kyunghee University, and he recently became a scholar known publicly by appearing on TV programs & # 39; Alleyshin 3 & # 39; (tvN). & # 39; Tremble and Reverberation & # 39; is a beautiful and living public science book that he published.
"The universe is trembling"
Let's start by talking about the title. Why did he mention the words "tremble" and & # 39; echoing & # 39 ;? The reason is that these two keywords can explain the mechanism of the universe.
The author said, "The universe is trembling. All stopped trembling." The problem is this is not a literary investigation. The table in front of you and the books on the bookshelf are also in the Jeongkungdong movement. Electron microscope observations can give a slight vibration to all.
When the vibration is long, it becomes a wave. Waves make the world. All waves and sounds are waves. So why is the word & # 39; eolim & # 39; in the title side by side?
"Humans resonate. We react with a lot of trembling around it. … We want to be the person who responds to shaking others. My echo is another vibration and I want to be rewarded with a new echo. Humans are very echoing and trembling."
In & # 39; shaking and echoing, beautiful and beautiful sentences like that point easily. The author uses two key words, trembling and echoing, as feed and warp, drawing a very large order of the universe.
This is a job that can feel intellectual pleasure if everyone thinks that it is difficult but does not have a lot of content. Thanks to the ability of the author to show off complicated content in literary style. The author writes, "I write in the hope that physics will look like a human," and wrote, "I try to tell physics through human feelings." That goal seems to have been achieved steadily. This is quite rigid and concrete so it does not need to be questioned whether a scientist writes a question or not.
The stories in this book are not really funny. Scientifically it is carefully examined for every type of Gotham theory that will be mentioned by famous East and West thinkers. & # 39; What is time? & # 39; & # 39; How much space is space? & # 39; & # 39; Death is something, & # 39; & # 39; How does the world work? & # 39; …
Among these questions, the physicist's view of death is very different from ordinary people. "When we know atoms, everything in the world starts to look different," he wrote. Everything that stands out is only "collecting atoms," so death is just an atom scattering. "An atom is eternal, so human birth and death are no different from the collection and spread of atoms."
It also impresses the reason why the world exists. To explain why the world exists, we must explain the beginning of the universe. Physicists think there is a "starting point" for the universe, which is the big bang. However, this does not mean that the universe was born when "banging" space. Before the Big Bang, there was no empty space itself. Why is the big bang theory convincing? That is the observation that the universe continues to grow. This result can be obtained by tracing the path of light originating from the past. To answer the question, "Why does the world exist?", You must be able to explain why the big bang happened. The author concludes the story of this question by introducing a sentence in Stephen Hawking's (1942-2018), "The History of Time."
"If we find the answer to the question why the universe exists, it will be the final victory of human reason. Only then will we know God's heart."
The world of science
Let us recall Albert Einstein's comments (1879-1955). "God doesn't play backgammon." The point of this statement is that all have a set of principles. If so, is there a "determined future"? The problem is chaos. There are complicated movements in a world that is difficult to predict. If so, is there no answer that humans can enjoy? Science is ultimately a study of agnosticism.
In conclusion, we have mathematical weapons. Science "is dominated by probability rules." If you throw & # 39; 1 & # 39; when you roll the dice, you cannot understand why this number is coming out, but you can see the possibility of & # 39; 1 & # 39 ;. We can solve many difficulties with a simple add / drop system.
"Mathematics describes nature in a very accurate and efficient way. … Physicists believe that even if he meets aliens, he can communicate in mathematics. I don't know whether the universe is really used in mathematics, or if we can only understand the world in mathematics, but without mathematics there is no physics. "
The universe moves according to the formula. One day is 24 hours. One year is 365 days. If you drop something on earth, it falls 4.9 m per second. But there are no specific reasons for appearance & # 39; 24 & # 39; & # 39; 365 & # 39; & # 39; 4.9 & # 39 ;. The same applies to other scientific laws. However, humans give up the meaning of something behind science. We think that humans appeared in this world, the extinction of dinosaurs, and shared love.
The author writes, "Humans give meaning to the universe without meaning and life." "Although meaning is only a product of imagination, it is humans to live like that. I do not know what happiness is, but people who try to live happily. Humans enjoy the universe without meaning happily, enjoying the imagination that they make in their imaginary systems. humans are more beautiful than the universe. "The white paper of this book is about drawing the world of science so coldly.
