1840Indian rebirth

The railway from Liverpool to Manchester was the first railway in the strict sense of the word.

The so-called "railway in the strict sense" is a railway without horse-drawn carriages. Earlier railways often used a mixture of steam and horses, with a strange style.

The horse-drawn carriage railway in the late Qing Dynasty is often regarded as a farce. In fact, it was a repetition of what the British had done.

People obviously prefer horsesless ones to those with horses.

Therefore, more than ten years ago, the Liverpool-Manchester Railway was born, and it successfully triggered the trend, and countries around the world began to build railways.

The railroads in the United States had not yet reached the west, so the Apaches who followed the horse whistles to ride the trains were seeing railroads for the first time, so they naturally observed every detail of the trains with curiosity.

The horse whistle is also sizing it up.

But what is different from others is that he is looking at the train with a mentality similar to archeology.

The locomotive had a striking chimney, which didn't surprise him, but beyond that, the train also had some notable horse-drawn carriage heritage.

For example, the driver on the train looks exactly like the driver of the carriage, sitting almost in the open behind the chimney, as if the boiler in front of him is the horse he wants to spur.

The carriage is similar to that of a horse-drawn carriage. It is made of wood, has a roof, and has windows on all sides. It is very simple.

Despite this, people are still very enthusiastic about taking trains, and almost every train is full of passengers, especially those who are boarding the train for the first time.

"It was this railway that started the railway craze around the world. Now almost all countries want to have their own railways like the UK." Mayo said.

Ma Shao asked: "When was it built?"

"It seems to be around 1830." Mayo said, "After it was built, it became an amazing investment project. As far as I know, people who hold its shares can get 10% of the income every year..."

Before boarding the train, the whistleblower noticed a detail - the spiral coupler.

At this time, trains still used spiral couplers to connect the carriages. This was an unreliable device. It used chains to hook up two carriages and then tighten them. It was inefficient and unsafe.

About twenty years later, the more advanced James replacement will gradually replace the spiral coupler and continue to be used for hundreds of years.

Ma Shao felt that he should have invented the Zhan's coupler in advance.

By the standards of his previous life, the experience of riding this kind of train was terrible. The road was bumpy, and the carriages were crowded, with people standing and sitting.

Fortunately, Liverpool and Manchester are not far apart, only a few dozen kilometers.

Two hours later, they arrived in Manchester and then headed to a residential area in the suburbs.

Salford, New Bailey Street.

There is always a faint smell of beer lingering in the streets, and the people living here are accustomed to it.

Because there is a brewery located here, the taste it produces has become a part of people's lives.

At this moment, in a villa near the brewery, the young brewery owner was writing something in his study.

"To William Thomson... Regarding the experiment of measuring the temperature difference of the waterfall last year, I have done some reflections. I have to say that this was a wrong idea..." the paper read.

At this moment, a woman walked into his room and said with some dissatisfaction: "Are you writing to Thomson again?"

"Yes, what's wrong?" The brewery owner touched the beard on his chin and considered the words in the letter.

"How could you do this! I am your wife, but you correspond with others every day!" the woman said again.

The brewery owner frowned: "Thomson is a man..."

"Isn't this even worse!" the woman said reluctantly, "It was this man who ruined last year's honeymoon. You measured the temperature difference of a waterfall with him, causing me to lose a complete honeymoon! And your measurement results were actually

Still found nothing!”

"Okay, okay, I'm sorry..."

The room was quiet for a moment.

The wife calmed down and then said, "We have guests coming."

"Who?" asked the brewery owner.

"William——"

The brewery owner blurted out: "Here comes Thomson?"

The wife took a deep breath: "No, it's William Mayo, your classmate."

"Mayo?" The brewery owner thought for a moment, then stood up reluctantly, "I'm not familiar with him, why did he suddenly want to visit me? I hope he's not here to borrow money..."

As a wealthy capitalist, he would meet old friends who came to borrow money from time to time.

Not long after, he met his old classmate William Mayo.

"Long time no see, Joule." Mayo greeted first, then turned around and said, "Great Chief, this is my classmate, James Joule."

Great Chief?

Joule couldn't help but feel confused, and at the same time he carefully looked at the person next to Mayo, a young man wearing a suit and with an unusually burly figure...a yellow man.

It was quite unusual to see a yellow race person here, and the title "Big Chief" made him even more confused.

"He is?" Joule asked.

Mashao took the initiative to introduce himself: "Hello, I am Mashao, the great chief of the Apache people in North America. If you think this name is difficult to pronounce, you can also call me 'Albert' - Isaac Albert is me

The English name of.”

While speaking, he secretly looked at Joule in front of him.

At this time, James Joule looked to be in his mid-twenties, very young. He was not the familiar old man in the textbooks, although he still had a lot of beard.

It's not the well-known unit of energy.

In 1848, James Joule was just a wealthy brewery owner and a modestly famous citizen scientist.

A few years earlier, his status in the scientific community could be described as a mountain village man.

Hearing Ma Shao's self-introduction, Joule's doubts did not diminish, but he still shook hands politely: "Hello."

Mayo explained: "Joule, you may know that I went to the United States the year before last. Chief Ma Shao was the friend I made in the United States."

"Welcome." Joule nodded and said politely, with a perfunctory look almost written on his face.

He never expected that this old classmate, whom he had not seen for a long time, would bring a North American savage over when they met. What did this mean?

However, what Ma Shao said next made him stunned.

"Mr. Joule, I have read almost all of your papers, about electric current heat generation, thermal work equivalent, thermal dynamic theory..." Ma Shao was familiar with the treasures.

"Especially the experiment you designed to measure the equivalent of heat work is very clever. I even bet that this will become a must-have content in middle school textbooks in the future."

Ma Shao added: "I completely agree with some of your most important points, such as heat should be the embodiment of motion, not the so-called 'thermal mass'."
