Then, Grandpa turned around and began to rummage through the bookcase in the room.

Naturally, Wu Zhenzhen immediately turned on the light in the room.

After some tossing, a very old copy of the Nobel Biography came out of the lowest level of the bookcase.

Grandpa patted the dust out of breath and said with a smile: "Okay, let's take this "Nobel Biography" and take a look." ”

So, in the next few days, Wu Zhen traveled through time and space and came to the era of Nobel.

It was a very tumultuous time, and with the rise of Prussia, the power of Europe as a whole became increasingly unbalanced.

On the one hand, the Great Powers were competing for colonies and semi-colonies throughout the world, and on the other hand, the power of Europe was becoming increasingly unbalanced.

Sweden gradually withdrew from the Baltic Sea competition as several rivalries with Tsarist Russia led to a decline in national strength.

However, the clash between Tsarist Russia, Prussia, Austria and the Ottomans in eastern Europe became more and more intense, and the situation in the entire Balkan Peninsula became more and more tense, even if Poland was divided, it could not be alleviated.

It was under such circumstances that Nobel began a life of legend.

Naturally, from birth, Nobel has formed an indissoluble bond with the military industry.

His father's words and deeds led Nobel to embark on the path of the military industry.

Because explosives were at the top of the profits of the military industry at that time, Nobel devoted almost all of his life to explosives.

However, the whole process was not all smooth sailing.

Since these countries on the border have great ambitions, there is never a shortage of orders.

The Crimean War, which took place in the Balkans, and the successive orders of Tsarist Russia allowed Nobel to complete the primitive accumulation of capital at once.

However, it was true that explosives were not very safe at the time. Because under the conditions of nature, it is easy to reach the critical point of explosion.

Although nitroglycerin has very good performance, it does have poor stability.

Therefore, a worker's mistake, even a small cigarette butt, can have very serious consequences in an explosives factory.

As a result, Nobel's younger brother lost his life in a very serious accident, which was a very huge blow. As a result, the factory in Sweden was forced to close.

Due to the relative peace in Europe for the next period of time, a series of accidents shut down all nitroglycerin explosives factories. After all, if there is no war, why would governments risk the production of such hard-to-preserve explosives?

Nature, a lesson from the past, a teacher of the future. Nobel began to look for ways to make more stable and safe explosives.

However, the series of research that began to expand with nitroglycerin was dangerous, after all, the study of explosives is something that ordinary people cannot imagine.

How many times the lab was destroyed, how many times Nobel was injured, there is no way of knowing.

However, the hard work paid off, and over time, it eventually paid off – relatively safe explosives were invented. Since it was indeed much safer to produce than the previous explosives, it was immediately rolled out throughout Europe.

Then, with the introduction of a series of new explosives, Nobel became one of the wealthiest industrialists in Europe.

However, by the age of forty, Nobel gradually began to reflect.

It seems that he is gradually beginning to love peace.

Of course, we don't know exactly what this is all about.

However, Leo Tolstoy's book "War and Peace", which reflected on the Crimean War, was launched almost around this time.

Then, the investment in Nobel Brothers also reaped great success.

As a result, all kinds of honors are also coming.

However, the good times did not last long, and Nobel, who moved to France, was not able to stay in France in the end.

In the following period, Nobel began his research in his new home in Italy, but Nobel, who was almost 60 years old, was clearly unable to work as much as he had done when he was younger.

After years of fatigue and various injuries in the experiment, his health deteriorated, and Nobel, who had a premonition that his time was short, returned to his native Sweden and began to prepare a will.

This is how the Nobel Prize, which had the greatest influence on the West in more than a century, was born.

Because the whole book is relatively brief, after reading it, Wu Zhenzhen only knows that so many things have happened in Nobel's life, he has studied very hard, and he has shown grief after the unfortunate death of his younger brother.

However, how exactly these things happened is unknown.

It seems that only a description of Nobel as a child seems more realistic, and the rest of the content seems to have a hint of fog.

So, after reading it, Wu Zhen asked his grandfather: "Why, I don't feel like I understand Nobel." ”

Grandpa smiled and said: "Haha, naturally it is impossible for you to understand it so easily, after all, the whole story of Nobel involves almost the whole of Europe and the modern times of the Americas, and it also has some influence on the East." ”

In this way, Wu Zhen understands that if you want to understand Nobel at a deeper level, you need more information.

When I finally got to the information technology class, when I opened the web page, it seemed that I could only turn to these Nobel Prize winners, and the information related to Nobel himself always seemed so scarce.

Naturally, this is the first time that I have been exploring but I can't find any answers.

Wu Zhen looked a little frustrated, after all, Nobel is such a great person, but the relevant information is so difficult to find.

When he got home, Wu Zhenzhen told Lao Wu about it.

Lao Wu thought for a while and said slowly: "This is normal, many things, it is true that you can't fully understand. Because, to further restore these things is also a very professional and time-consuming work. ”

After a pause, Lao Wu continued: "For example, many scholars who study "Dream of Red Mansions" have spent their whole lives figuring out some things about Cao Xueqin's era. ”

So, Wu Zhenzhen is no longer entangled in this.

After passing the exam, the seats in the classroom were adjusted again, and the adjustment made in this class meeting was relatively large.

The class was divided into 16 groups, which seemed to be a bit peculiar in that they were divided according to the average score of the group.

In other words, the 16 groups all have almost the same average score, and it seems that the process of finding the average score is complicated so late that this new seat was launched so late.

After all, in order to divide such a group of 16, the first step is to ask for an average score of all possible four people of all 60 students.

And the number of times this is calculated is naturally very large. After all, according to the number of combinations, there are 60 combinations, and there are different combinations of C (60,4) in a group of 4, so the number of times the average score to be calculated is as high as nearly 500,000 times.

Then, according to the requirements of a group of two boys and two girls as much as possible, it seems that Teacher Guan has been very strong in completing this task in more than two weeks. Take a look at the latest chapter of "Real Perspective Claw Book House" to read for free for the first time.
