- Time Capsule.
Bai Yang has wanted to buy this thing for a long time.
His plan is obvious. BG4MSR claims to live in 2040, so as long as Bai Yang sends a slow delivery that spans twenty years, if the other party can receive it, it will prove that what she said is true.
?It sounds simple and straightforward, but when you think about it, it is very difficult in practice. To prevent cheating, fraud, lying, and loss, it must be within the capabilities of a high school student.
Place an order!
Bai Yang bought a small time capsule, made of stainless steel, with two wrenches and a shovel as a gift, sixty-eight yuan each.
It's so expensive, it will hurt for a while.
So what should I give?
What should go in a time capsule?
food? drug? souvenir? a letter?
No, none of this matters.
The most important thing is the timer, which is a watch. Bai Yang needs a clock that can keep time. When the time capsule was dug out from the ground, the clock was rediscovered, and it could tell people how much time had passed.
No clock can be kept in a time capsule for 20 years and still run normally. The battery life of an electronic quartz watch is only five to ten years. The automatic mechanical watch does not use a battery. It uses a tourbillon to wind up the mainspring, but relies on external vibrations to provide energy , the pointer will stop if it is left standing for a long time.
How to do this?
With the current advanced technology of human beings, it must be a matter of minutes to manufacture a timer that can continue to work for twenty years, but Bai Yang can't do it. He is just an ordinary high school student with limited ability and financial resources. His greatest reliance is It is the shopping sites Taobao and JD.com.
Bai Yang tried to search for "timer" on Taobao, but most of the results he got were ordinary electronic clocks, and it was impossible for them to last twenty years in the time capsule with his toes. All you need is a clock, you don¡¯t need any bells and whistles, you just need to keep time¡ªlisten, how simple it is, isn¡¯t it your job as a clock to keep time?
But how long will it last?
At least twenty years.
This is not easy. It is not easy to achieve the ultimate in simple functions. Bai Yang really couldn't find a suitable target for a while.
He sat on a chair, staring at the phone screen, lost in thought.
Twenty years is too long. In daily life, except for the house and the furniture used in the house, there are very few things designed and used in units of twenty years.
"Twenty years"
Bai Yang frowned and muttered, playing with a coin in his hand.
It was a Morse code practice coin. Bai Yang bought it when he was practicing the constant-width newspaper. It was about the size of an ordinary one-dollar coin, but the Morse code and their corresponding letters were engraved on the front and back. It looked golden, but in fact Made of stainless steel, copper plated.
But in the end, Bai Yang didn't develop his ability to send telegrams. His father said that he would be useless if he practiced blindly like this. The bad habits he practiced could not be changed. He attributed the responsibility to the fact that the Changshu K4 key he bought on Xianyu was a pirated copy.
"Twenty years, how can we persevere through these twenty years?"
This problem is not so complicated at first glance.
After careful consideration, I realized that it was extremely difficult.
When time itself becomes a stumbling block in front of you, what you have to face is the most powerful force in the world.
Since man-made creations are unreliable, we can only place our hopes on the physical laws of the world itself¡ªchanges in the natural world are always measured in millions of years, and twenty years are but a snap of the fingers.
Bai Yang's first thought was oxidation.
"Oxidation?"
Oxidation of iron, or oxidation of copper.
Iron is oxidized to ferric oxide, the color is red, and copper is oxidized to copper oxide, the color is green.
If Bai Yang can use the color change caused by metal oxidation, for example, when BG4MSR digs out the time capsule, she will see the metal time marker placed in the capsule.
At this time, Bai Yang only needs to ask the other party, the color of the marker - this thing cannot be faked, and the other party does not know the meaning of the color, so they can't lie - to know whether the girl is telling the truth.
"Can this method work?"
"It won't work."
Bai Yang shook his head.
It doesn't work.
The time capsule is strictly sealed, and it is not breathable or ventilated at all, so how can there be so much oxygen.Bai Yang's second thought was evaporation.
He thought of the legend that the Mausoleum of the First Emperor Qinshihuang was filled with mercury. There are rivers, lakes and seas with mercury, and boats can be sailed on rivers, lakes and seas. The volatilization speed is extremely slow. If he puts 0.5 grams of mercury in the time capsule, it may take more than ten years for this mercury to completely volatilize
When BG4MSR opens the time capsule twenty years later, she will see - a high concentration of mercury vapor.
Neither will this.
Isn't this harmful.
Bai Yang scratched his head.
This doesn't work, and that doesn't work, what should I do?
It's a pity that there is no second person present to discuss this issue with him. Two brains are definitely better than one. Otherwise, he could still have a brain on his ass to help him think. In the silence, the small alarm clock on the desk was ticking. It was very late at night, and the rain outside the window seemed to be still falling.
That night Bai Yang lay on the bed unable to sleep, his eyes wide open, staring at the ceiling in the darkness, thinking about this question over and over in his mind.
He hoped to find a method, a method that could not be faked, it would not be disturbed by any external force, and the result would not be tampered with by anyone, and only the iron of this world could control its changes, just like when trees die and turn into coal, rocks are turned into coal. Erosion forms caves¡ªlet the world itself be a timer, only in this way can it be called an ironclad proof.
That's what I said, but it's easier said than done.
As a high school student, it is still too difficult to find such a method, Bai Yang thought silently, maybe change to someone else, someone who is older and has more life experience, and the method will come out as soon as he thinks about it. Or is she too young and too ignorant Can she think of a good way to replace Brother Yan? Can He Leqin come up with a good solution?
He Dashao has seen a lot since he was a child, and he has gone abroad more times than he has gone out of the province. Maybe he can think of a good way?
Forget it, Bai Yang shook his head, He Leqin failed the physics test again and again, his chemistry test score was lower than physics, his daily homework had to be rescued by Bai Yang and Brother Yan, and he was addicted to PlayerUnknown¡¯s Battlegrounds all day long, ass total war Assassin¡¯s Creed Dark Souls European truck Microsoft Flight Simulator Half-LifeHalf-Life is really a bad translation, it is the first of the top ten bad Chinese game translationsWho translated it into Half-LifeWhat was the original name of Half-Life?
Bai Yang thought wildly.
The original name of Half-Life?
It seems to be half
half life?
Bai Yang was stunned for a moment, and sat up in shock in his dying illness.
