Shangwen shrugged helplessly.One of his arms was still injured.Can it be fast?But it is also hurt.Many things are handed over to others.For example, approval of documents.Meng Yi took on the vast majority.In this way, Shangwen has a lot of free time.Otherwise he would have absolutely no time to do so many experiments.
Naofumi soon started working on telegrams.In fact, the telegraph that Shangwen made was a Morse telegraph, not the 26-key telegraph, magnetic needle telegraph, and five-needle telegraph that appeared before this telegraph.The principle of these telegraphs is very simple.They all use electromagnetic induction.But his g is bad.Or not suitable for current requirements.for example. 26 keys.Utilize the electromagnetic induction phenomenon to absorb the small pieces of paper with letters written on them with the small copper balls that are energized.This accuracy is poor.And regardless of the pointer at the back, the system established by the five needles is based on 26 letters.Instead of the later simplified code composed of dots and horizontal lines.This code can represent numbers.letter.punctuation marks and more.There are tens of thousands of words.Representing it with numbers just simplifies it.
Shang Wen directly jumped over a large distance of invention.Morse built a telegraph.Its sending device is very simple and consists of electric keys and a set of batteries.Press the button and the current will flow.Press for a short time to indicate a dot signal, and press for a longer time to indicate a horizontal line signal.Its telegraph device is more complicated, is made up of an electromagnet and related accessories.When a current passes through, the electromagnet generates magnetism, and the pen controlled by the electromagnet also records points or horizontal lines on the paper.The effective working distance of this transmitter is 5 meters.This is the telegraph that Naofumi will be working on.
But it will cost a lot of money to popularize it on a large scale.The price of natural resin is definitely not cheap.The number is very rare.And because of the location.The latitude is above twenty.There is no safety zone in tropical climate areas.None of the rubber.can think of.The insulating material is too large for Qin's electrical power.Those Qin scholars who study electricity need to spend a lot of money to have insulated wires tens of feet wide.
"Call".Shangwen let out a heavy breath.Naofumi made a telegraph machine according to the appearance of the history museum.Shangwen looked at it for a while.It was already past two o'clock in the middle of the night.Naofumi stayed up all night again to complete a new invention.But this invention is very worthwhile.
The advent of the telegram.Make the world suddenly small.Information transmission has become extremely convenient.think about it.Trains are getting bigger and bigger.Start faster and faster.The telegraph can transmit messages from thousands of miles away in a short time by pressing the button.This is definitely a big advantage militarily.
The opponent just moved out.We will know by telegram.The highest level also knows.via telegram.The King of Qin can convey news to the frontline commanders as quickly as possible.Think of it as an advantage.But insulating the wires becomes a hassle.His price can be compared with gold.But it's not impossible.The use of coal will provide Shangwen with new insulating materials.No coal.And oil.The potential of these two industrial raw materials is huge.
The reason why Shangwen invented the telegraph may be subconsciously.The inducement may come from the earthquake in Daidi.The speed of information dissemination has caused many people to die because of untimely rescue.This made Shangwen hang in his heart.Telegraph is also in the experimental process.There was a hazy feeling.But it's all right now.The telegram finally came out.
Because of the telegram.Shang Wen was very excited.He decided to step up.Invent the camera too.Give Ying Yu a big surprise.Everything is conceived.There was still some silver halide left unused in the morning.Naofumi decided to make some more.Because there is also a large amount of silver halide needed to develop a photo.Moreover, it is necessary to temporarily transform the room as a darkroom for developing photos.
502 camera
The best photosensitive material is silver bromide.Preparation of silver bromide.Sodium bromide is much more common than potassium bromide.Silver bromide is produced by reacting sodium bromide with silver nitrate.All this had to be done in a darkroom.But Naofumi covered it with a large blanket.Then take a lampshade made of red paper and cover it on the kerosene lamp.Because of the kerosene lamp.Shang Wen had to come out to take a breath.Or set it up with a stand.
There is silver bromide.Photographic gelatin is barely there.Because gelatin needs fresh beef bones to be made after ninety to one hundred days.But things have gotten to the point where it's barely usable.
The next step is to make a camera.Make a portable wooden box camera according to the local method.Naofumi needs to make two.One for viewing and one for taking pictures.The shutter is also a mechanical shutter.
Follow Shangwen's instructions immediately.The camera must also have a focal length.For measurement.Shang Wen spent a lot of thought.With the help of triangulation.Calculates the distance of a third point from the distance of two known points.This method has been widely used in artillery and architecture.And based on this, some people began to give birth to geometry.A lot of people are doing research.Because the areas involved are very broad.Shangwen did just that.He has to calculate the appropriate distance based on triangulation.Later generations of cameras all have this distance measuring device.
There is also a rotatable mirror.The whole camera is made of two wooden boxes.This will allow you to adjust the focus.
Naofumi made a twin-lens reflex camera.This suddenly spanned the history of the camera several times.But Shangwen is still satisfied.And flash.Early flashes were spotlights.Naofumi made an umbrella shape out of tinfoil.Magnesium is then electrolyzed.
Magnesium has been recognized in Qin's laboratory.It is mainly produced by electrolysis of lime.Active metals such as sodium and potassium were also prepared by point solution method.This made Qin's chemical technology advance again.These are all thanks to Bai Ai.Continuous research and development experiments based on a booklet of limited knowledge.
The use of electrolysis also discovered a poisonous gas.Chlorine.At the same time, another hydrochloric acid was obtained.These are all produced by electrolysis of salt water.As for efficacy.Laboratory personnel are still working on it.
Chemistry has been recognized by more and more people.Some arsenals began to specifically link chemistry to weapons manufacturing.It is mainly used as propellant for muskets.But progress has been very slow.Shangwen remembers that a gunpowder worker discovered smokeless gunpowder because the fiber material used was catkins.Catkins are the best fiber material that Qin State has found so far.It is used in many places.Such as papermaking.Banknotes and checks require a lot of catkins to make high-end paper.This pushes up the price of catkins.Use catkins to make smokeless gunpowder to shoot powder.It seems a bit extravagant.For this reason.It caused Qin to go astray in launching gunpowder.They turned to other alternative medicines.Because of the relationship between smokeless gunpowder.machine gun.And the development of other bullet types has been slow.
But if there is a loss, there must be a gain.The R&D staff invented another hair-shot drug.picric acid.But he mainly used it on shells.This made Qin State start a large-scale advancement in artillery technology.Some people started making breech-loading guns based on pressure cookers.Medicine kits also began to use metal barrels.The emergence of detonators.Let an expensive single-base charge shell appear.But there was a problem with the barrel.Because the artillery still uses bronze or copper as the launch tube.The demand for steel is brought up again.People have reached a point where there is an urgent need for steel.
Steel needs repeated forging and pressing to come out.This led some to find new ways to make steel.This time, though, it's chemistry.Because chemistry uses a series of chemical agents to measure its composition.And make a foundation for mining minerals.
Naofumi's camera has already done almost the same.The rest is photo paper.Look at the time and it's five o'clock.Shangwen decided to take a break.But Ying Yu was too excited to fall asleep.Because of sunglasses.Lots of sunglasses.She wants to try it.
With that in mind.She was turning left and couldn't sleep.Turn right to sleep.
"Why is it still dark? My sunglasses!" Ying Yu took the sunglasses and put them on.
"No. I have to get up." Ying Yu immediately turned over while speaking.The maids she was messing with had to be busy too.Ying Yu was so excited.She kept urging to hurry up.
When it's almost over.He put on a pair of big brown toad mirrors early and walked out the door.
Just went out.Seeing Ying Yu's attendant was taken aback.
"Ah" Many attendants knocked the guys in their hands to the ground.
"What is it called? Have you never seen this princess wearing sunglasses? Huh!" Ying Yu planned to appear in a brand new posture.I didn't expect that someone didn't understand.This is such a disappointment.
King Qin got up early, and Zhao Gao followed King Qin after serving King Qin.There are very few documents approved by King Qin himself.So Qin Wang has more free time every day.
"Zhao Gao, is today's newspaper here?" King Qin asked.
"Young one, go get it now." Zhao Gao bowed respectfully and prepared to leave.When he was about to turn, Ying Yu suddenly appeared wearing sunglasses.
Zhao Gao, who had never seen such a dress before, was frightened to the ground.
"This..." Zhao Gao didn't say anything.
"Hey, I was taken aback! These are sunglasses!" Ying Yu said.
"Get up!" Ying Yu said.
"What are you doing wearing a mask?" King Qin turned his head and asked attracted by Zhao Gao's voice.
"Father! This is not a mask. These are sunglasses. They block the sun." Ying Yu stepped forward and took off the sunglasses and handed them to King Qin.
"Oh! Mr. Qin made it for you, right?" King Qin asked.
Ying Yu nodded in agreement.
Qin Wang put on his sunglasses and took a look.
"Hey! Why is it so dark today? Wouldn't it make you invisible if you wear it?" King Qin asked strangely.
"It needs to be used after the sun comes out. After the sun comes out, there is no need to dazzle." Ying Yu explained.
"Yes." King Qin really wanted to try it.But the sun had not risen in the morning.Sunglasses are not very useful.
"Tell me, what else did Mr. Qin invent?" Qin Wang took off his sunglasses and asked.
"Father, how do you know that there are new things invented?" Ying Yu asked.
"Look at you!" King Qin replied.
"Look at me." Ying Yu was puzzled.
"You came so early, there must be other things. Tell me!" King Qin said.
"Hmm." Ying Yu was still puzzled.But the father had to answer the question first.
"What kind of telegram is he studying. It's the one that can send the news all at once. There's also a camera. It's the thing that can draw the father and the king at once." Ying Yu answered truthfully.
"Oh! The widow is going to take a look." King Qin said.
"Zhao Gao, prepare the car!" King Qin shouted loudly.
503 Wife?eggplant!
"Hey! Idiot, wake up!" Ying Yu patted Shang Wen's forehead and shouted loudly.
"What's the matter?" Shangwen woke up reluctantly and asked.
"Get up quickly. I want to see the new things you invented." Ying Yu shouted loudly.
"Wait a minute." Shang Wen still wanted to sleep for a while.
"Don't wait. My father and king are here." Ying Yu said.
"Come as soon as you come... who, who is here?" Shang Wen finally realized.
