Chapter 329 Great cause of science
Many people participated in the discussion.

Sleepless for you tonight and said: "Although I also want to believe that your guess is true, after all, if Liu Shiyuan, the golden hand, is Liu Shiyuan, his reputation should be even more prominent. Just what you said proves that This result is somewhat far-fetched."

The meteor flying across the starry sky also said: "Yes, I also feel that what you said is really far-fetched. If you want to attract attention, don't use this method. I also hope that what you said is true, so that Liu Shiyuan can't use genius To describe it, it must be described as a monster."

Ziyun Ziyun said: "I don't think there is much difference between yes and no. If it is true, Liu Shiyuan can't add much reputation to Liu Shiyuan, and if it's not, it can't reduce Liu Shiyuan's reputation much."

However, this news only appeared in the post bar of Liu Shiyuan's fan group, but it was quickly denied.

It didn't have much impact on Liu Shiyuan either.

Now Liu Shiyuan is preparing to publish a paper in the identity of Nai An, and this paper is the element of radium.

He is also the first person in this world to discover this element.

Radium, chemical formula Ra, atomic number 88, atomic weight 226.0254, is a natural radioactive element. The name of the element comes from Latin, which means "ray".

In 1898, the Curie couple discovered radium from the uranium slag. In 1902, 90 mg of radium chloride was isolated, and the atomic weight of radium was initially determined.Radium is widely distributed in nature, but its content is very small. The content in the earth's crust is one part per billion, and the total amount is about 1800 million tons.All isotopes of radium with a mass number of 206-230 have been found, of which only radium 223, 224, 226, and 228 are natural radioactive isotopes, and the rest are synthesized by artificial nuclear reactions.Radium 226 has the longest half-life and the largest natural abundance, and is the most important isotope of radium.

Radium is a silvery white lustrous metal with a melting point of 700°C, a boiling point of 1140°C, a density of about 5 g/cm, and a body-centered cubic lattice.The chemical properties of radium are active, similar to barium.

Metal radium can react quickly when exposed to air to form oxides and nitrides; it can react with water to form radium hydroxide; the newly prepared radium salt is white, and changes color due to irradiation after being placed.

Radium is the most important radioactive substance before the rise of the modern nuclear industry, and it is widely used in the fields of medical treatment, industry and scientific research; mixing radium salt and zinc sulfide fluorescent powder can make permanent luminescent powder.

Radium is a highly toxic substance.

In 1898, Madame Curie and her husband (Pierre Curie) discovered the element radium, which caused a huge sensation in the world of physics.

Radium is a by-product of uranium production. When uranium is leached from uranium ore with sulfuric acid, radium becomes sulfate and exists in the slag, and then it is converted into radium chloride. Using barium salt as a carrier, fractional crystallization can be obtained to obtain pure radium salt.

Radium and its decay products emit gamma rays, which can destroy malignant tissues in the human body, so radium needles can cure cancer.After mixing radium salt and zinc sulfide fluorescent powder, it can be made into a permanent luminescent material, which can be applied to clocks and various instruments to glow in the dark. It is a luminous watch.

In industry, radium is used as a γ-ray source for flaw detection, and non-destructive inspection of internal cracks and defects of metal materials.

In scientific research, it is used for radium gamma standard source and radium-beryllium neutron standard source.

The above is all of Liu Shiyuan's memories, and this is also the information Liu Shiyuan will write in "Dream World".

Of course, Mrs. Curie and her husband (Pierre Curie) will also be written by Liu Shiyuan in "Dream World".

Of course, this book contains all the memories of Liu Shiyuan in his previous life.

The scope is very wide, and it simply cannot be completed in a few years.

This is a very large project.

However, Liu Shiyuan only provided an article introducing the characteristics, refining methods and uses of radium, or a work on chemistry.

Nai An's identity has performed well in the fields of physics, mathematics, and biology.

He has all the performances in science, only the talent in chemistry has not been shown.

This article just makes up for this shortcoming.

In mathematics, there is a book "1+1" theory, in physics, there are "artificial black hole conjecture" and "atomic bomb conjecture", and in the field of biology, there is "Origin of Species".

The least important thing is mathematics. Although the physics room is loved by many people, the military of various countries are naturally the most concerned about these.

However, these things have naturally received widespread attention. Although Liu Shiyuan's identity is known to everyone in the entertainment industry, his influence is far less profound than that of Nai An.

Songs, entertainment circles, etc. are all pastime things, and they are also dispensable things, but science has a great influence. After all, people's desire for knowledge is much greater than people's demand for music.

Even in a very small country, there will be a group of people with a strong desire for knowledge to study Liu Shiyuan's stuff. After all, knowledge can change everything.

At this time, Cui Wenxu stood behind Liu Shiyuan in silence.

She didn't know how she was feeling.

Liu Shiyuan is not only Yuan Shi, an Internet writer, Liu Shi, a master of music, but also Nai An, who has shaken the scientific world.

No wonder Liu Shiyuan was able to turn Jin Jaejoong around.

No wonder he was able to escape from many dangers calmly.

Because he is Liu Shiyuan, he is a legend.

"Husband, can you tell me what identities you have? Why do I feel that I still don't know you?" Cui Wenxu said.

"Xiaoxu, I only have three hidden identities, one is the original stone, one is the golden hand Liu, one is Nai'an, and the other is my real identity.

In the past, I didn’t think carefully, and I was afraid of causing unnecessary trouble. Although there are talents who speak 72 languages ​​in this world, there are also great writers in this world who write novels of tens of thousands of words a day.

But there are still very few people who span so many fields.

I was afraid of causing trouble, so I used three identities, and now one and a half of them have been exposed. I didn't think how long I could hide these identities, I just thought that these identities would give everyone time to accept my identities. "Liu Shiyuan turned around and said with a smile.

"Husband, you are really amazing. Why do I feel that I am not good enough for you now? Ever since I met you, I feel that you are the only one in my life. Many people say that when I know you To be honest, I didn't even think about the achievements you have achieved now. I just thought that if you can't support your family, I will support you instead. But your performance later really surprised me and even made me Many people were taken aback." Cui Wenxu looked at Liu Shiyuan with some admiration and said.

　Sorry, my wife is here, tomorrow is too difficult. Three chapters and eight thousand words
