As a popular country around the world, bowling is naturally the United States. In the early 1940s, bowling was a very popular sport, just like baseball and American football. At that time, there were about 6,000 bowling alleys in the United States, and in the future, Walmart supermarkets across the United States did not play this number.

Before the 1950s, automatic bowling bottle staking machines had not appeared, so at that time, they were all manpowered to set bottles. The bowling alley would hire some children to stand behind the ball bottles and be responsible for setting the ball bottles. Like many waiters, these children who put the ball bottles were basically unpaid, and the reward was entirely due to tips given by customers. It is also a normal phenomenon in the United States, a country where tip culture is prevalent.

In 1952, the launch of the automatic bottle staking machine made the children who put the bottle unemployed. Bowling has achieved a leapfrog development. The bowling alley no longer needs manpower to put the ball, and the management cost has been greatly reduced. It has become possible for one person to manage a bowling alley. The bowling alley has also expanded rapidly throughout the United States.

In the era when bowling was the most popular, there were more bowling alleys in the United States than gas stations. There might be only one gas station in a small town, but there might be two bowling alleys. Even in small villages like Nevada, there would be bowling alleys.

Although American bowling in the 1940s was not as prosperous as it was more than ten years later, the 6,000 bowling alleys in the United States were still a big market. If these more than 6,000 bowling alleys were all made of Chen Qiang's bowling, it would be enough to make Chen Qiang make a fortune.

The price of resin bowling balls is much lower than that of natural rubber bowling balls. Those bosses who run bowling alleys are not fools, so of course they know how to choose.

Soon, all bowling alleys in New York were used with resin bowling, followed by the branch bowling produced by Bakerland Company, which was transported to Washington along the railway and to Chicago, spreading across the United States.

At this time, there is no need to send salesmen from Bakerland. Naturally, there are agents of sports goods coming to Bakerland to order goods and earn the difference from it. A bowling ball with a cheaper price, so you don’t have to worry about having no sales.

...

Little Beckland looked at trucks pulling the newly produced bowling balls out of his factory, and his heart was filled with a sense of accomplishment.

Before this, Beckland's main business was to use phenolic plastic to produce bakelite, such as light switches, instrument cases, telephone handset shells, etc. It was also thanks to Beckland's father, Old Beckland, who was the inventor of phenolic plastic, that Beckland could do a good job in bakelite business.

Little Beckland doesn't want to keep making light switches. He wants to expand the company's business projects, so he has made many attempts to develop new products, but none of them succeeded. The more failed case is that Little Beckland missed polyamide synthetics and nylon, the most popular textile material during World War II.

Now, by producing bowling, Bakerland has finally found a leading product other than Baker. He is no longer the "Bakland who only knows how to produce light switches"!

Although the profits of bowling have not been counted yet, and even if the profits are counted, it will be distributed to Chen Qiang, Beckland is already very satisfied. As a bowling producer, he is very clear about the production cost of resin bowling. In addition to the shipment of bowling, he can estimate how much money the bowling ball has made him earn.

"That Chen Qiang, is Helmes's incarnation? Last time he asked him to look at the polyethylene tube, he made a hula hoop, and this time he asked him to look at the polyurethane, and he made a bowling ball again. This guy really has a sense of business. With such talent, it's a pity to be an athlete without doing business." Little Beckland sighed secretly.

Hermes is the god of business in Greek mythology, equivalent to the Western God of Wealth. Beckland compared Chen Qiang to Hermes, and he also agreed with Chen Qiang's ability to turn stones into gold.

The next moment, Little Beckland slapped his forehead: "By the way, I have created a lot of new materials a few years ago. I will look back and show this Chen Qiang. Maybe he can come up with something new product!"

...

In the laboratory of Bakerland Company, Chen Qiang stood in front of the sample shelves, looking confused.

Next to him, Little Beckland looked at Chen Qiang with anticipation and asked, "How is it? Did you think of new products when you see these materials?"

Chen Qiang smiled helplessly: "If you think the new product is a cabbage, you can think of it anytime and anywhere!"

"The new materials I have developed in recent years are here. If you think about it carefully, what else can you do?" Little Beckland said unwillingly.

"In fact, there are many things that plastics can do, but the current craftsmanship and plastics are not tough enough, which limits the development of plastic products." Chen Qiang said.

"Then I may be able to develop what kind of plastic you need, how tough and how strong it is." Bakerland immediately spoke. For this technical entrepreneur, studying new materials is still his daily life.

Seeing Little Beckland's passionate look, Chen Qiang was really embarrassed to attack his enthusiasm. Chen Qiang felt that he should find a way to deal with Little Beckland, so Chen Qiang said, "Have you ever made a thread with plastic?"

"The outer skins of wires were made." Bakerland replied truthfully.

"The kind of wire and skin is not good. I'm talking about a relatively durable wire, similar to a sheep intestinal wire!" Chen Qiang said.

"Can we use fiber to synthesize something like sheep intestinal thread? This should not be difficult. However, with current materials, it is impossible to achieve the toughness of sheep intestinal thread." Little Beckland said.

"You can try the nylon that became popular last year. Perhaps this material can be made into a more durable thread." Chen Qiang reminded.

"Okay, I'll go to the lab to try it. But what are you going to do with this kind of wire?" Little Beckland asked.

"Of course, it's a tennis line." Chen Qiang paused and continued: "Now the tennis line is made of goat intestine line, which is not cheap, and it is prone to decay over time. I think a new tennis line that is cheaper will definitely have a market."

"I almost forgot that you have won the US Open championship. You must have the right to speak in this regard! But this is just right. When I really develop a new tennis line, we will save even the endorsement fee." Bakerland said.

"That's right. At that time, I will use the new tennis line to go to the US Internet and win a championship. It will be better than any advertisement!" Chen Qiang nodded.

The development history of the sheep intestine thread is almost the history of the development of tennis. People first invented the sheep intestine thread to use it as a tennis line for tennis rackets. The first tennis line in history was an ordinary sheep intestine thread.

The tension of the sheep intestine line is very good. Using the sheep intestine line as a tennis line, the biggest feature is that it feels very good when playing.

From the 19th to the 20th century, humans' craftsmanship for making sheep intestines has been continuously improved. From the early days, they could only use the sheep intestines of eight-month-old sheep, to later use cow intestines, and later even the intestines of horses, donkeys, mules, and kangaroos, they could make sheep intestines.

The use of sheep intestine thread is becoming more and more widespread. In addition to making tennis threads, you can also have surgical sutures, make various bowed string instruments, etc. Even in modern times, most string instruments use steel strings, but there are still performers who pay attention to timbre and use sheep intestine thread as the strings of the instrument.

Sheep intestinal stitch is a natural material that will inevitably be affected by temperature and humidity, and its durability is not particularly good, so if it is used as tennis stitches, it will have a relatively large impact on players.

For example, in Wimbledon's game, it often rains during the game. At this time, the tennis line made by the sheep intestine line will change due to the humid air. For players, it is likely to be two different games before and after the rain.

The durability of the sheep intestine line was not a problem in the 1940s. The skills and strength of tennis players in the 1940s were not as good as those of later generations, and the sheep intestine line could still hold on. If it were in the future when tennis heavy gunners were everywhere, the sheep intestine line might break if it couldn't hold on for a few servings.

Attenuation is also a major problem with natural materials. Over time, the attenuation of sheep intestinal lines will become more and more severe, so the frequency of changing tennis lines by tennis players in that era is definitely much more frequent than modern times.

The biggest problem with using sheep intestinal thread as tennis line is the cost.

The main reason why tennis is called aristocratic sport is that it costs a lot of money, and this money is spent on rackets.

A tennis ball is not worth a lot of money, and a flat tennis court is easy to find, but the price of a tennis racket is very high. The reason why tennis rackets are sold is expensive is because the tennis line is valuable. In the early stages of tennis, three cows need intestines to make a tennis line for a tennis racket. Therefore, early tennis balls had such high requirements for dressing. If they were not dressed neatly, they would be sorry for the intestines of the three cows. At that time, only aristocrats could afford this sport. In countries like China, where oxen are particularly expensive, it was impossible for them to slaughter three cows to make a tennis racket.

The so-called "noble movement" was really a sport that only aristocrats could play at the beginning of their invention. For example, bowling was originally a religious ritual. In Europe at that time, ordinary people were not qualified to participate in formal religious rituals. To participate in formal religious rituals, let the bishop talk in front of you, it was all the privileges of the nobles. Only ordinary people would not bother to pay attention to you.

For example, billiards were made of ivory in the early days, because wooden billiards and copper billiards would deform after hitting, and ivory was not easily deformed. However, ivory is a very expensive material. Just imagine that except for the nobles, ordinary people would not be willing to play ivory balls. If they accidentally break them, they would not be able to afford it.

In the future, due to the emergence of various new materials, tennis lines will no longer use goat intestine lines. Of course, some tennis rackets that claim to be high-end, such as some luxury sports brands in France, will still use natural tennis lines. However, high-level professional tennis players will definitely not use natural goat intestine lines as tennis lines. After all, goat intestine lines are too durable. Top players such as Federer and Nadal, their rackets are specially made by sponsors, and the materials even contain many high-tech elements.

Chen Qiang has some understanding of tennis lines. In the future, there are single-core single-layer structural fibers, single-core multi-layer structural fibers, multi-fibers, and composite fibers. The materials are varied and each has its own advantages.

The most popular one is the single-core single-layer fiber tennis line. This tennis line feels very close to the natural sheep intestine line, and is more durable than the natural sheep intestine line. It does not agree to attenuation. More importantly, this tennis line is very cheap, so it is also the most popular. As for other types of tennis lines, many of them are developed from single-core single-layer fiber tennis lines.

The raw material of this single-core single-layer fiber is nylon, that is, polyamide fiber.

For Bakerland, a plastic expert, nylon is not a very fresh material, so Chen Qiang simply told Bakerland that nylon can make tennis lines. As for whether Bakerland can develop nylon tennis lines in the end, it depends on his ability.

If Beckland could develop a nylon tennis line, Chen Qiang and Beckland, the partner of Beckland, would inevitably make a big profit. The price of nylon is not high. If nylon is very expensive, it would not be possible to make hundreds of millions of pairs of stockings to sell to the whole world. Compared with the sheep intestinal line, the price advantage of the nylon tennis line is too great. Once the nylon tennis line is released, people will definitely choose cheaper nylon tennis line and give up the expensive sheep intestinal line. Of course, there will always be those who deliberately pretend to continue to use the sheep intestinal line.

Moreover, the emergence of nylon tennis lines can also reduce the cost of tennis, and it is also a good thing for the promotion and popularization of tennis.

...

The domestic situation is still very bad. After the Japanese army landed in Zhejiang and Fujian, they launched an offensive in the Second War Zone. Although Chief Yan of the Second War Zone had five armies and was also very good in weapons and equipment, they still chose to "preserve their strength". As a result, the Japanese army easily occupied the eastern Jin area north of the Yellow River.

Subsequently, Japan began a new round of bombing on Chongqing. This time, not only did it blow up the US Embassy in China, but it also sank a US gunboat parked on the Yangtze River.

This move was interpreted as Japan's revenge on the United States, because not long ago, Japan occupied French Indochina, which is now Vietnam, Laos and Cambodia. In response, Roosevelt announced that it had frozen all Japan's assets in the United States. At the same time, Roosevelt also appointed MacArthur as the US military commander in the Philippines, obviously guarding against Japan's attack on the Philippines.

Before that, Roosevelt also announced that all assets of Germany and Italy in the United States would be frozen, and the consulates of Germany and Italy in the United States would be ordered to close, and their staff would also have to leave the United States within ten days.

The United States' attack on Germany and Italy did not affect the process of the European war. In Europe, the war entered a new stage. After repeated attacks on Britain without success, the German army finally pointed its finger at the Soviet Union.

On June 22, 1941, Germany tore up the Soviet-German Treaty of Non-Aggression and launched an attack on the Soviet Union in three groups. Countries such as Lithuania, Finland, Hungary, Slovakia, Bulgaria, Czechoslovakia and other countries also sent troops to support Germany and launched an attack on the Soviet Union.

Among these countries, such as Finland and Lithuania have suffered in the hands of the Soviet Union, such as Finland was taken away by the Soviet Union, Lithuania was forced to join the Soviet Union, etc. Now that there is a chance to oppose the Soviet Union, these countries that have suffered in the hands of the Soviet Union will naturally not hesitate and immediately stand on the side of Germany.

Several other countries are also German brothers. Some countries have gained a lot of benefits in the process of Germany conquering Europe. For example, Hungary gained a lot of territory in the process of dividing Slovakia and Yugoslavia. Since they took the benefits from the Germans, they naturally had to help Germany send troops to fight the Soviet Union. Romania received Germany's promise to get half of Ukraine after invading the Soviet Union.

The war was also as recorded in history. The German army advanced rapidly, while the Soviet army retreated step by step. In just 18 days, the German mechanized troops advanced more than 600 kilometers. In just the first day of the battle, the Soviet army lost 1,200 aircraft.

The Soviet legions were repelled one by one, and the dissatisfaction with the Soviet Union in the Baltic Three Kingdoms and Western Ukraine began to erupt. The Soviet army, which was fighting locally, was trapped in the ocean of people's war. There were always a large number of leading parties in the attack of the German army.

The Soviet Union gave up the Baltic region, Minsk, the Black Sea port, and Kiev. In the end, the Soviet Union had to adopt the policy of scorched earth resistance, so that Germany could not get supplies as much as possible. The Soviet leader even said in a public speech: "When our troops had to retreat, they had to transport all railway rolling stocks and vehicles without leaving a locomotive or a carriage for the enemy, and no kilogram of food or a liter of fuel for the enemy!"

Implementing a scorched earth policy in its own country can be said to kill 800 enemies and lose 1,000 of them. The current Soviet Union is really forced to the edge of a cliff.

In September, the German army surrounded Leningrad, the Soviet industrial city, and prepared to launch an attack on Moscow.

For the Soviet Union, the only good news may be that the winter this year came earlier, and just as September began, Russia had its first snow.

However, this first snow not only did not stop the Germans from attacking, but instead made the Germans step up their attack. At this time, the Soviets had to ask the United States for help. Soviet foreign accountants Molotov urgently asked for US representative Avil Harriman to seek support from the United States.

The Americans did not expect that the Soviet Union would lose so quickly and so badly. The United States would definitely not allow the Soviet Union to fall so quickly. So Roosevelt urgently approved a billion-dollar aid. However, if the Soviets wanted to receive this aid, they had to save Moscow first. If Moscow was lost, the Soviet Union would be not far from the destruction of its country, and it would be useless to ask for assistance.

It was also at this time that Chen Qiang received a letter from Esther, and the movie he invested in was finally finished.
