What is time?

In scientific terms, it is a parameter used by human beings to describe the process of movement of matter or the process of occurrence of events!

In order to understand the time represented by the day more accurately, various timers have been created, the basic principle of which is to calculate the average time consumed by a certain thing in the process of operation.

For example, the time used to divide the seconds, minutes and hours is divided by a drop of water, a handful of sand is exhausted, and a candle is burned, but this division is obviously not accurate enough, because the time of each drop of water falling cannot be completely equal, and there will inevitably be a lot of error.

The pendulum clock invented by Sean is undoubtedly more advanced, because according to the law of single pendulum, with the help of gravitational potential energy, the time spent on each swing of the pendulum is exactly the same, and its energy consumption is very small, and only one mainspring is needed to run for a long time.

So it was only necessary to find something that was equally isochronistic, but more precise, to be able to create an efficient timepiece that was different from a pendulum clock.

Listening to Lynn's story, Sean frowned, this is easy to say, but it is not so easy to find a suitable isochronism law.

"I can tell you two things that have the law of isochronism, and all you have to do is think about how to make them into timers." Lynn said with a smile.

Sean paused for a moment and looked at Lynn in surprise, he didn't expect that the speaker had found other isochronous laws, and there were still two.

"The first is a crystalline of quartz, made of silica, which has an interesting property of generating an electric current on the surface when pressed by an external force.

If positive and negative currents are introduced on both sides of a quartz crystal, the crystal will deform and oscillate at a specific frequency......"

Lynn succinctly explained the operation principle of the quartz clock to Sean, and the simple point was to use the characteristics of quartz crystals that will constantly oscillate after being applied to the interactive current to record time.

Because the vibration frequency of the quartz crystal is very stable, normally engineers will make this thing into a tuning fork by cutting the quartz crystal and controlling the current, and oscillate at a frequency of 32,768 Hz per second.

If we take each vibration as a benchmark, a quartz clock made using this principle can divide time into 32,7868th of a second.

Of course, the upper limit of the amplitude frequency of quartz crystals is far more than that, and it is not impossible that the technology is enough to reach the level of 100,000 or even millions per second.

After Lynn explained the principle of crystal vibration, Sean immediately became excited, and he made the pendulum clock, so he was naturally able to realize the important role of this thing in timekeeping.

Especially in terms of precision, the pendulum clock is completely outrageous.

It can be expected that his invention will be eliminated before it is implemented.

Sure enough, the insight and knowledge of a legendary speaker are not comparable to that of a full-fledged wizard.

The eager, excited expression on Sean's face quickly turned to helplessness, and he said with a wry smile. "Now that you have an idea and a plan, why not just make this quartz clock."

Lynn has found the most important isochronous law of crystal oscillator, and the problem is only one, that is, how to record every crystal vibration.

He didn't think that this question would be difficult for Lynn, who was a magic star.

Because of this answer, even I can think of myself, since quartz can be electrified, it would be good to work on electromagnetic signals!

"I've always believed that professional things need to be done by professional people." Lynn said with a smile.

If it had been a few minutes ago, Sean would have happily accepted the praise of this magic star, but now he was a little crying and laughing, because Lynn had just explained the principle of the quartz clock very clearly, and the professionalism made him embarrassed.

Then there is only one answer left, and the speaker can't spare much time to dump these gadgets, so he lets himself do it.

Thinking of this, Sean didn't know what expression to make for a while, if he could complete the production of this quartz clock, there was no doubt that he would be able to get a Morning Star medal again.

This is another timekeeping revolution compared to pendulum clocks, allowing wizards to accurately identify very small time scales.

However, it is such a glory, but the other party doesn't care about throwing it to himself.

It took a while for Sean to adjust, and nodded in response to the magic star's request, after all, it was a good thing no matter how you look at it.

On top of that, if the quartz clock had been invented by someone else, the Morning Star Medal he had received for making the pendulum clock would probably be questionable.

After all, his pendulum clock is a clumsy toy in comparison......

"By the way, you just said that there is another law of isochronism in addition to quartz crystals?" Sean asked with great curiosity.

"You should have read my published paper [The World of Probability: Quantum Mechanics], right?" Lynn asked rhetorically.

"Yes, yes, but I haven't fully figured out the probability theory and duality you proposed." Sean had a slightly embarrassed look on his face.

"It's okay, I'm afraid no one dares to say that they can understand quantum mechanics now!" Lynn said with a smile.

"Can't even you?" Sean asked curiously.

Although he couldn't fully understand the quantum theory of this magic star, he read it several times, and the logic was very rigorous and self-contained, and it was also consistent with the results of the double-slit interference experiment, which could explain various strange phenomena in the quantum field well.

"Of course not!" Lynn shook his head, let alone him, even the Federation in the previous life had not been able to truly perfect the quantum theory.

According to a friend he knows who studies phenomena in the microscopic realm, the gap between the current cutting-edge quantum theory and actual observation is about a hair's length from the Earth to Uranus......

This is undoubtedly very small and basically does not affect the application of its results, but since there is a gap, it means that the quantum theory has yet to be perfected, and at least there is some unknown interference that has not been found.

"If you've read my paper, you should know that when the electrons inside an atom jump between two energy levels, they absorb or release electromagnetic waves, which is also how laser magic works."

"However, the atomic clock uses another characteristic of it, the electromagnetic wave released by the same element when it transitions in a specific orbit, and the oscillation frequency is very stable, which is a fixed value."

"For example, the electromagnetic oscillations produced by rubidium atoms can reach a frequency of more than a billion times, which means that if the technology is sufficient, it can be separated, and the ...... of a billionth of a second"

Lynn gushed endlessly, and Sean, who was listening to it, would already be dizzy.

Using the frequency of electromagnetic wave vibrations generated by atomic transitions to time?

The Speaker's brain hole really embarrassed him.

It's just a clock to make, is it really necessary to make such a big battle, and measure it so accurately?

Perhaps seeing Sean's thoughts, Lynn opened his mouth to explain. "For macroscopic nature, there is no need for billionths of a second of accuracy, but when it comes to experiments and observations at the atomic level, or even quantum level, it is necessary."

Due to the issue of secrecy, Lynn did not say that the new timer would be used to measure the flow of time, but only used quantum experiments as an explanation.

"Here I recommend three elements - hydrogen, rubidium, and cesium, and you can experiment with them one by one." Lynn suggested.

"Speaker Lynn, I can still think of a way to find that quartz vibration detection device, but I'm afraid I don't have the ability to make this atomic clock." Sean felt that the speaker in front of him was really thinking too highly of himself.

He's just a little formal wizard, and the principles of atomic clocks involve laser emission, the internal structure of the elements, and even quantum theory, which he doesn't even feel confused to hear, let alone make.

"If you don't try hard, how do you know you can't do it? You can take my handwritten book to the Academy of Magic for help, and if there is any problem that they don't understand, you can always ask me. ”

Lynn said encouragingly, and then asked Sean to get the quartz clock out first, and then slowly study the atomic clock, and strive to get it within a year!

As long as he succeeds, his name will surely leave a strong mark on the history of magic, and time will be redefined because of these achievements!

Under the wonderful prospect and repeated assurances of Lynn, Sean couldn't help but be moved, it was undoubtedly a very tempting condition to be able to get the guidance of the speaker at any time, and after hesitating for a while, Sean agreed to give it a try, but there was no guarantee that the atomic clock would be made.

After seeing Sean leave, Lynn couldn't help but smile on her face, and in this way, she once again solved a necessary matter.

The quartz clock is okay, and he can do it in a few days if he wants, but the process of the atomic clock is very complicated, and it is definitely not possible to make it with the current level of craftsmanship in the Magic Kingdom.

But fortunately, they have a miracle called magic, which can make up for the lack of materials and craftsmanship, and all they need is to constantly come up with ideas and experiments.

This is undoubtedly a very time-consuming task.

Lynn, who became the speaker, naturally would not bow down to everything, otherwise he would not have to die of exhaustion, and Sean was the one he chose.

It is not difficult to discover the law of the single pendulum, but according to Sean's description, he intuitively perceives that the time of each pendulum swinging back and forth is very close to each other, not as linear as logic expects, and then verifies it experimentally.

This kind of insight is the best way to invent and create!

After Lynn gathered her thoughts, she didn't stop for a moment, and asked the squire to inform Haroff, Aurora, and Vittorio that she needed to hold an internal impromptu meeting.

When the Speakers arrived, Lynn repeated the information she had received from Bard and the Raven in detail.

"Do the two worlds have different rates of time? This is great news! Aurora said happily.

It was widely believed that war could break out in three months, and in extreme cases even within a month, but now it seems that there will be more time than expected.

Afterwards, the few people discussed how many men should be sent and which space-time gate to enter to investigate.

This number cannot be too much, nor too little.

Once there are too many of them, it is easy to attract the detection of the Lord of Necromancy, and the location of the space-time gate will be exposed in advance, if it is less, and the whole army will be wiped out in danger, there will not even be a person to report it.

After deliberating, they quickly decided to form a nine-member team consisting of a great wizard and eight official wizards, and the location of the entry also excluded the two nodes of the Holy City and the City of Fire and Oil, and chose the space-time gate located in the north.

There are three reasons for this, the first is that Bard's intelligence makes them not ignorant of the situation in that area.

Second, if the Church's expeditionary force can enter it in large numbers, then they should have no problem sending people in.

Thirdly, the dangerous monsters there have been cleaned up by the expeditionary force and should be slightly safer.

Overall, it's the best choice.

……

A week passed in a flash, and Sean's research and development speed was a little faster than Lynn expected, and it only took six days to get it done.

During this time, with the Parliament's half-year development plan, the entire Magic Kingdom also attracted a second wave of construction boom, various cities were building roads, building workshops, everyone was too busy to stop, the number of laborers alone has exceeded a million, and many wizards are even more distressed.

Because there is too much technical work to be able to do magic, many wizards have to juggle multiple tasks at a time.

Lynn had to ask the council to spend some of its resources on the laying of the magic signal tower, and as long as the magic net could be officially operated, tens of thousands more official wizards could be created in an instant.

The council's grain collection plan is going very well.

With the lessons learned from the bankrupt colleagues in the last grain war, even the wealthy businessmen who regard money as their life do not dare to engage in the kind of strange goods, not to mention that the parliament is very generous and can make a fortune at a price 30 percent above the market.

If you want to say that what really makes Lynn and the others feel a headache, is the selection of personnel who enter the space-time gate.

This group of people is called the exploration team at the best, and the death squad is the death squad at the worst sound, and the wizards who enter it need to be prepared for unexpected situations and cannot return, if they are discovered or captured by the lord of the necromancy, they must also take the initiative to trigger the backhand and kill everyone present from the material and soul level, so as to avoid the other party getting too much information about this side.

So it required that every candidate be trustworthy, shrewd, decisive, and sacrificial, until seven days later, when the nine men were selected on the basis of presumption and voluntariness.

On the day of departure, Lynn dropped the research project in his hand and personally came to see off a few people.
