Everything is echoing and trembling – Kookmin Ilbo

This joke appears in Cosmic Connections, the first mass science book published by astronomer Carl Sagan (1934-1996). He went to dinner with a publisher planner and a polynesian restaurant in Boston, USA. "You will soon be asked to decipher important messages." Is this a coincidence? In fact, he became the best-selling Cosmic Connection, and his successor Cosmos became a long-standing astronomical bridge connecting Earth and Space. People love her more.

However, the person who received the request to decipher the important message would not be the only one. Many scholars who shine like stars around the world are still trying to evaluate the order of the universe or to inform people about the order.

Kim Sang-wook (48) can not be forgotten when mentioning one of those who play such a role in Korea. He is a physics professor at Kyunghee University, and recently he has become a scientist who is known to the public, showing in the TV show "Alleyshin 3" (tvN). "Tremble and Reverberation" is a beautiful and lively public science book that he published.

"The universe is trembling"

Let's start talking about the name. Why did he mention the words "chills" and "echoes"? The reason is that these two keywords can explain the universe mechanism.

The author says: "The universe is trembling. All the stops are chills." The problem is that it is not literary exploration. The desk on you and books on the bookshelf is also in the Jeongkungdong movement. Observation with an electron microscope can vibrate a little.

If the vibration is long, it becomes a wave. The wind makes the world. All waves and sounds are waves. So, why is the word "eolim" in the name next?

"People are echoing. We react with great trembling in the neighborhood … We want to be the person who responds to another trembling. My echoes are another shivers, and I want to receive rewards with a new echo." People are so echoing and shivering. "

"Chills and Echoes" makes such a beautiful and beautiful sentence easy. The author uses two keywords, shivers and echoes, like tissue and metas, creating a huge universe order.

This is a work that can be intellectually joyous if everyone thinks it's hard, but it does not have a lot of content. This is due to the ability of authors to display 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 with the help of humanitarian senses." It seems that the goal has been achieved evenly. It is sufficiently rigorous and specific that there is no question of whether the scientist writes any questions or not.

Book stories are not really fun. Scientifically thoroughly tested all the types of Gotham theorem, which might be mentioned by the famous East and West thinkers. "What is the time?" "How many places are there?" "Death is something", "How does the world work?" …

From these points, the glance of the death of a physicist is very different from that of ordinary people. "When we know the atom, everything begins to look different in the world," he writes. All that stands out is just "atomization", so death is just a dispersal of the atom. "The atom is immortal, therefore, the birth and death of a person are not different from atomic assembly and dispersal."

It's also impressive that the reason the world is there. To explain why the world exists, we must explain the beginning of the universe. Physicists think the universe is a "starting point", which is a big bang. However, this does not mean that the universe was born while "reflecting" the space. Before the Big Bang itself was not empty. Why is the theory of big bang convincing? This is an observation that the universe is constantly expanding. This result can be obtained by tracking the past light path. To answer the question: "Why is the world there?", You should be able to explain why a big explosion took place. The author concludes a story about this issue by introducing the sentence "The History of Time" by Stephen Hawking (1942-2018) in Seedevra.

"If we find the answer to the question of why the universe exists, it will be the ultimate victory of the human mind. Only then will we know the heart of God."

The world of science

Let's remind Albert Einstein's remarks (1879-1955). "God does not consider the bekgeme". The essence of this statement is that everything has a set of principles. If yes, is there a "certain future"? The problem is chaos. There are complex movements in the world that are difficult to predict. If so, is there no answer that people can enjoy? Science is ultimately an agnostic study.

In conclusion, we have a math weapon. Science is dominated by the probability law. If you throw in the dying "1", you can not understand why this number came out, but you can see the option "1". We can solve many difficulties with a simple add / drop system.

"Mathematics describes the nature of the incredibly accurate and effective … Physicist believes that even if he meets an alien, he can communicate in mathematics. I do not know if the universe is really used in mathematics, or if we can only understand the world in terms of 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 the ground, it will decrease by 4.9 m per second. But there is no particular reason for the 24 "365" to "4.9". The same applies to other scientific laws. However, people pass on something to the back of science. We think that people appeared in this world, lost their dinosaurs and shared love.

The author wrote: "People give meaning to the meaningless universe and live." "Although the meaning is just the product of imagination, a person lives in the same way. I do not know what happiness is, but it is the people who try to live happily." Happily, a person enjoys the senseless universe, enjoying the imagination that he created in his system of imagination. So, man is more wonderful about the universe. "The white paper of this book is that it attracts the world of science without being cold.
