1840 Indian Rebirth

Chapter 175 [Joule]

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

The so-called "railway in the strict sense" is a railway without a carriage. The earlier railways are often mixed with steam and horses, and the style of painting is weird.

The horse-drawn carriage railway in the late Qing Dynasty is often regarded as a farce, but it was actually doing what the British had done.

People obviously prefer horseless horses to horseless ones.

So more than ten years ago, the Liverpool-Manchester Railway was born and successfully followed suit, and countries all over the world began to build railways.

The railways in the United States have not yet spread to the west. The Apaches who followed the horse post to take the train were seeing the railway for the first time, and naturally observed every detail of the train curiously.

The horse whistle is also looking at it.

However, unlike others, he looked at the train with an archaeological attitude.

The locomotive had a prominent chimney, which didn't surprise him, but otherwise, the train had some notable horse-drawn heritage.

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

The carriage is also similar to that of a 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 riding the train, and almost every train is full of passengers, especially those who are boarding the train for the first time.

"It is this railway that sparked the railway craze all over the world. Now almost all countries want to have their own railways like the UK." Mayo said.

Ma Shao asked, "When was it built?"

"Looks like 1830 or so," Mayo said. "When it was built, it became an amazing investment. As far as I know, people who own shares in it can get 10% a year. . . . "

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

At this time, the train was still using a screw coupler to connect the carriages. This is an unreliable device. It is inefficient and unsafe to hook up two carriages with an iron chain and then tighten them.

About 20 years later, the more advanced Zhan's will gradually replace the spiral coupler, and it has been used for hundreds of years.

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

According to the standards of his previous life, the experience of taking this kind of train was terrible, the road was bumpy, the carriages were crowded, full of people, there were stops and seats.

Fortunately, Liverpool and Manchester are not far apart, only a few tens of kilometers away.

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

Salford, New Bailey Street.

The street is always filled with a faint smell of beer, lingering, and the people living here are also accustomed to it.

Because there is a brewery here, and 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 is writing something in his study.

"To William Thomson... I have had some reflection on last year's experiment to measure temperature differences at waterfalls and I have to say it was a poorly conceived..." 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 the matter?" The owner of the brewery touched the beard of his chin and carefully considered his words in the letter.

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

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

"Isn't this even worse!" the woman insisted, "It's this man who ruined last year's honeymoon. You measured the temperature difference of a waterfall with him, and made me lose a whole honeymoon! And your measurement results are actually Still nothing!"

"Okay, okay, sorry..."

There was a moment of silence in the room.

The wife calmed down, and then said: "There is a guest."

"Who?" asked the brewery owner.

"William—"

The brewery owner blurted out, "Is Thomson here?"

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

"Mayo?" The brewery owner thought for a moment, then got up reluctantly, "I don't know him well, why did he suddenly want to see me, I hope he didn't come to borrow money..."

As a wealthy capitalist, he meets old friends who come 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 his head and said, "Chief, this is my classmate, James Joule."

Great Chief?
Joule couldn't help feeling puzzled, and at the same time carefully looked at the person beside Mayo, an unusually burly young man in a suit... a man of yellow race.

It was quite unusual to see people of the yellow race here, and the title "Great Chief" made him a little confused.

"He is?" Joule asked.

Horse Whistle took the initiative to introduce himself: "Hi, I am Horse Whistle, Great Chief of the Apaches of North America. If you find this name a mouthful, you can also call me 'Albert' - Isaac Albert is me English name."

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

At this time, James Joule looked 28 and [-] years old, very young, not the familiar image of the old man in the textbook, although he also had a lot of beard.

Not even the well-known energy unit.

In 1848, James Joule was just a wealthy brewery owner and a popular scientist.

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

Hearing the self-introduction of the horse whistle, the doubts in Joule's heart did not decrease, but he shook hands politely first: "Hello."

Mayo explained: "Joule, you may know that I went to the United States the year before last. The Chief Horse Whistle is a friend I met in the United States."

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

He never expected that this old classmate, whom he hadn't seen for a long time, brought a North American savage over when they met. What does this mean?
But what the horse whistle said next made him stunned.

"Mr. Joule, I have read almost all of your papers, about current heat generation, thermal work equivalent, thermodynamic theory..." Horse whistle is like a treasure.

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

Ma Shao said again: "I very much agree with some of your most important points, such as heat should be the embodiment of movement, not the so-called 'heat mass'."
