"Divide it evenly into sixty parts,"
"Each serving is for one minute."
"Make another minute hand,"
"Used to calculate minutes."
The Taoist priest opened his mouth wide.
Finally, she lowered her head and replied, "Yes!"
Add a minute hand,
It's not as simple as it sounds.
The leader opens his mouth,
The subordinates were running themselves ragged.
Once Wang the Taoist priest finishes making the minute hand system...
Then it's time to let him design the timekeeping system.
.....
Kaifeng is a very large city.
Therefore, there is more than one bell and drum tower.
The Sui, Tang, Song, and Yuan dynasties,
There are also bell and drum towers in the imperial city.
I don't know why it was abolished in the Ming Dynasty.
A clock that is off by two quarters of an hour per month.
Zhao Yuan's senses were already quite accurate.
So he ordered the making of two more large pendulum clocks.
They were placed on the Bell Tower and the Drum Tower respectively.
The pendulum clock that has already been completed,
It was then placed in the Daqing Hall.
Used for telling time when the emperor and his ministers attend court assemblies.
The bell and drum towers in Kaifeng are laid out in an east-west direction.
The Drum Tower is in the east, and the Bell Tower is in the west.
It was a very tall two-story building.
The base is exactly like a city wall.
There is also a pedestrian archway below.
Including the stone base, there are actually three layers.
Zhao Yuan planned to build those four-sided clocks.
You can see it from all four directions.
He asked Wang the Taoist priest if it would be difficult.
The answer I got was:
Design and manufacture four clock faces.
It's much simpler than adding a minute hand...
On the contrary, the Chinese-style roof of the clock tower,
This thing is not suitable for installation.
During the late Qing and Republican periods,
They also have similar worries.
The solution was extremely crude.
They simply cut a hole in the roof of the Bell and Drum Towers.
Build a small Western-style clock tower up there.
In the blink of an eye,
Just like the top of a traditional clock tower,
A single horn suddenly grew from the bone spur.
It's incredibly ugly!
But its advantage lies in saving money and hassle.
Zhao Yuan certainly didn't need to save trouble.
Let the professionals do the work.
Benefiting from Emperor Huizong of Song's large-scale construction projects,
It has produced many excellent architects and craftsmen.
The Ministry of Works quickly provided the design.
Narrowing the top floor of the clock tower,
Continue by adding three more layers on top.
The layers gradually narrower and narrower.
Like a Buddhist pagoda.
I don't know when it started,
Tokyo residents suddenly realized that
The drum at the Drum Tower is no longer sounding.
All you can hear every day is the clock tower chiming.
After making careful inquiries, I learned that
The upper floors of the Drum Tower are being demolished and rebuilt.
Nobody took it to heart.
They were used to being tormented by Emperor Huizong of Song.
As long as they don't forcibly demolish people's houses, nobody cares.
Before the finished pendulum clock was moved to the Daqing Hall...
They even managed to get some to keep at the East Palace for a few days.
Zhao Yuan's wife and children all came to watch the spectacle.
I found this thing very novel.
Why can this needle keep moving?
Liu Huiniang squatted in front of the clock.
After looking at it for a while, I couldn't help but ask a question.
Zhao Yuan explained simply,
"That thing that swings back and forth is called a simple pendulum."
"If there were no air or mechanical resistance,"
"It can keep swinging indefinitely,"
"To power this pendulum clock."
"The thing next to it that looks like a weight is called a hammer."
"Pull up the heavy hammer,"
"It has a downward force,"
"Used to compensate for the frictional resistance experienced by a simple pendulum."
Chapter 1753 Natural Disasters
Liu Huiniang blinked.
It seemed like they understood.
It's as if I didn't understand anything at all.
"I know about friction; my father told me about it!"
The seven-year-old eldest son, Zhao Kang, raised his little hand.
Zhao Yuan asked, "What else do you know?"
Zhao Kang replied, "My father said, 'My toy wooden ball is to roll out.'"
"If there's no friction, it will keep rolling."
"It only stops because of friction."
"Hahaha!"
Zhao Yuan couldn't help but burst into laughter.
Hu Sanniang stood to the side with a beaming smile.
Her son,
She was bright and clever from a young age.
He was extremely favored by Zhao Yuan and his son.
In contrast, Zhao Yang, the legitimate son born to Li Shishi,
He looks rather dull.
He doesn't talk much normally.
In comparison,
Zheng Yuanyi inevitably developed other thoughts.
The other concubines didn't have as many ideas.
Anyway, their children will definitely not be crown princes.
Hu Sanniang said, "I have been studying physics in recent years."
"But he hasn't learned about the simple pendulum yet,"
"I don't know what principle it uses."
"Bring me paper and pen, I'll draw it for you," Zhao Yuan said.
Liu Huiniang immediately had a palace maid bring paper and pen.
They easily attracted Zhao Yuan's attention.
Hu Sanniang was quite helpless.
She really didn't understand those kinds of knowledge.
Li Shishi sat down beside her with a smile.
He spoke in a low voice to Pei Chang'e.
He seemed completely unaware that someone was vying for his favor.
Zhong Miaoyun stood beside Liu Huiniang.
Listen patiently as Zhao Yuan explains the principle of a simple pendulum.
