Lam vaguely remembered that the experiment went well that day, so he was in a good mood.
As soon as he came out of the laboratory door, he saw Wei and ran over excitedly, holding an astronomical telescope in one hand and a drink in the other, asking him to follow him to the roof to enjoy the star sky.
The stars were bright that day, and the dark night was filled with countless stars, twinkling constantly.
Wei and Lam climbed to the top of the building and looked up at the stars. They couldn't help but marvel. This also aroused their curiosity.
They wanted to know what the world outside the earth was like. What impressed Lam the most was that Wei said at that time that it would be great if he could touch the boundary of the universe in his lifetime. Even death would be worth it.
But what did this sentence have to do with the number of Osiris?
Lam thought about this sentence carefully and found that it really had nothing to do with it, so he continued to search in his mind for the scene of watching the starry sky with Wei.
At that time, Wei was looking at the galaxies outside with an astronomical telescope, and he uttered a word or two of praise from time to time.
Lam finally squeezed Wei out of the way to grab the telescope. Looking out through the telescope, Lam saw distant galaxies, mysterious nebulae, and starlight that took countless millions of years to reach the earth.
Lam took up his position and looked intoxicated, letting Wei whisper something in his ear and turned a deaf ear.
Wei finally grabbed the spot and explained some astronomical concepts to Lam while watching.
Lam remembered that Wei introduced several novel concepts to him. There was one concept in particular that Wei said that the ancient Hua country had already discovered it as early as ancient times, and it was much more accurate than the West.
What was it? Lam suddenly couldn't remember what it was called.
Lam felt that the concept was about to come out, but he couldn't say it for a while. It seemed that there was some difference, related to the year.
Year, year, year, one year equals one year, yes, it is precession. The concept Wei told himself at that time was precession of the equinoxes.
According to the astronomical concept,precession of the equinoxes refered to the long-term precession of the earth's rotation axis, which caused the vernal equinox to move westward along the ecliptic, causing the tropical year to be shorter than the sidereal year.
As for the tropical year, it was the time interval between the sun passing through the vernal equinox twice in succession, that is, the time it took for the sun to shine on the vernal equinox this year until the sun shone on the vernal equinox again next year.
The current tropical year was 365 days, 5 hours, 48 minutes and 46 seconds.
The sidereal year was when the center of the earth started from a certain point in the sky, circled the sun once, and then returned to this point.
The time of a sidereal year was 365 days, 6 hours, 9 minutes and 10 seconds. Therefore, the time difference between the sidereal year and the tropical year was named precession of the equinoxes by the astronomy community.
In the fourth century AD, Yu Xi, an astronomer from the Jin Dynasty , discovered that the positions of stars were slightly shifted when analyzing ancient star charts and starry skies. He then discovered the precession of equinoxes and determined that the winter solstice would move back one degree every 50 years.
In the second century BC, when the ancient Greek astronomer Hipparchus was compiling a star catalog containing 1,022 stars, he calculated that the vernal equinox moved westward by one degree every 100 years. Yuxi was older than the conclusion reached by Hipparchus.
Lam remembered that Wei said that according to modern observations, the vernal equinox moved one degree westward, or the time it tookd for the precession of the equinoxes to move one degree was 72 years.
After introducing the precession of the equinoxes, Wei told Lam the myth of Osiris. He said that in the myth about Osiris, Osiris was murdered by Seth and 72 of his men. He also asked Lam if he was magical.
Later, Wei looked at the starry sky and began to lament the insignificance of human beings, and also admired the wisdom of the ancients.
At the same time, Wei believed that small ants like humans could define so many rules and discover so many phenomena in just a few thousand years. There must be other reasons behind it.
Wei speculated that the civilization of the previous era must have existed before the current civilization era, and then the seeds of civilization were passed down in some unknown way. After hearing this, Lam smiled noncommittally and thought it was because Wei's imagination was too rich.
At this time, Lam completely recalled the scene, but he knew that the answer was definitely not the number 72.
The password he just entered 72 showed was wrong. Lam could now confirm that the reason why Wei gave the number of Osiris was to make Lam think of the key clue of precession of the equinoxes, and 72 was a key number.
The tale has been taken without authorization; if you see it on Amazon, report the incident.
But Wei only told himself about Osiris and the precession of equinoxes. At most, he had one more key clue, 72, and 72 was still the wrong answer, so what was the correct answer?
Lam thought for a while and then looked at the information on his phone. He felt that the numbers of Osiris might have to be disassembled for analysis. The answer might lie in the clues represented by Osiris and the numbers respectively.
The numbers were easy to say, but they were related to the precession of equinoxes, and the base number of the precession of equinoxes movement was 72.
As long as we found out the clues hidden in Osiris, we could get the complete password.
Osiris was the god of ancient Egypt, so the place to stay should be ancient Egypt.
What was there in ancient Egypt? Lam blurted out without thinking, the Nile River, the Pharaohs and the pyramids. The most mysterious and famous thing about ancient Egypt was the pyramids.
"Mathilda, can you help me find some books on the study of the Egyptian pyramids? The more the better, the faster." Lam turned to her and asked, and then turned around to continue thinking without waiting for a reply.
After making a few calls, she found books on pyramid research in a bookstore. There were many books on pyramid research, but Lam couldn't read them by himself, so he asked everyone to read them together to see if they could find any clues.
Lam told everyone that as long as they saw books with words related to pyramids and numbers, they could bring them to him and take a look at them, and he would analyze them.
"Dr. Lam, you see, this book states that the distance from the earth to the sun is between 146.24 million kilometers and 151.36 million kilometers. Therefore, people define the average distance between the earth and the sun as 149,597,870 kilometers as an astronomical measurement unit, and the height of the Khufu Pyramid is 146.59 meters. If multiplied by one billion, the result is 146.59 million kilometers, which is exactly within the range of 146.24 million kilometers to 151.36 million kilometers." Wang searched for a few books and finally found something similar to the pyramid. There was a description related to numbers, so she excitedly showed it to Lam.
Lam took a few glances, and silently matched the precession of equinoxes movement base number 72 in his mind.
He found that there was no relevant connection, so he shook his head at Wang, indicating that Wang had to continue looking.
Wang shrugged, flipped through the rest of the book, and found that there was no other relevant description. She could only throw the book aside and continue looking.
After reading a lot of books, a book describing ancient Egyptian mathematics finally caught Lam's attention. The above view was that the Egyptian Pyramid of Khufu may have been reduced to the ground in the northern hemisphere of the earth according to a scale of 1:43200.
Lam carefully read the argument of this book, which stated that the circumference of the earth was about 24902.45 miles, the radius from the equator to the North Pole was about 3949.92 miles, and the circumference of the Pyramid of Khufu was 3023.16 feet and the height was 481.3949 feet.
Assuming that one mile equaled 5280 feet, 24902.45 miles equaled 131484936 feet, and 3949.92 miles equaled 20855578 feet.
If reduced according to the ratio of 1:43200, 131484936 feet was approximately equal to 3023.63 feet, and 20855578 feet was approximately equal to 482.768 feet.
Considering that the earth was an ellipse and was wide at the equator and narrow on both sides, these errors can be ignored. The pyramid was a proportional projection of the northern hemisphere on the ground.
After reading the entire argument, Lam couldn't help but sigh.
Recalling what Wei said, it might be true that as Wei said, there were countless civilizations before this civilization, and each civilization might be the inheritance of the previous civilization.
Otherwise, how could it be possible to make such accurate calculations based solely on the level of ancient science?
Lam read the content in the book again and stared at the key ratio number 1:43200 for a long time. 43200 was 600 times the precession moving base of 72, which was equivalent to 43200 years for the precession to move 600 degrees. The answer was possible 43200.
Lam quickly entered the number 43200 into the password box.
After waiting anxiously, the password box popped up with the message that the password was incorrect.
Lam raised his eyebrows. Why was it wrong again? It shouldn't be. All the reasoning was consistent. After all, What went wrong?
Lam looked at the two numbers and then started to mutter, 43200 and 72 years, a precession of one degree was 72 years, and a precession of 600 degrees was 43200 years.
The current clues must be inseparable from these two numbers. Lam told himself in his heart not to worry but to be stable. Now he just needed to find out the relationship between the two.
600 degrees was 360 degrees plus 240 degrees, which was equivalent to the precession of more than a week.
Lam knew where the problem lay. Generally, calculations were based on one cycle, and 600 degrees had exceeded this benchmark.
So what were the numbers that were both multipliers of 72 and divisors of 43200 within a 360-degree precession movement? Liam calculated that there were quite a few.
Let's try starting with relatively simple numbers.
Lam followed the decimal calculation habit and started from 6 degrees. 72 multiplied by 6 equals 432. Lam entered 432 and the password was wrong.
Lam then tried 60 degrees. 72 times 60 equals 4320. He entered 4320.
Lam waited for a while and was about to try another number. Unexpectedly, the password box prompted that the password was correct.
When Lam saw this, he couldn't help but feel a little funny.
Sure enough, Wei understood him, or Wei understood the psychology of ordinary people.
When ordinary people encounter this kind of situation, they would indeed choose to start from the simple to the difficult. It can be said that Wei had predicted it.
Lam opened the email with the "O" title, but found that there was nothing in it and the content was blank.
What did Wei mean when he sent a blank email to himself?
Lam began to secretly guess again, could this email represent zero, and should he guess the address from this zero?
No, that shouldn't be the case.
In the last email, Wei obviously wrote the exact street name. It stood to reason that he would have to tell himself the specific house number next.
How could he give himself a blank email? Could it be that Wei was on purpose to confuse others?
The more Lam thought about it, the more likely he felt that this was a possibility. It seemed that he still had to decrypt the next email and find the corresponding clues from the next email.
Just as he was thinking about it, the person in charge of network security pointed to his screen and told Lam and others that hackers were attacking the entire network and trying to invade Lam's computer.
Now they could only cut off the external network and form their own local network.
Lam looked at the screen and found that there were indeed a large number of attacks, and there were also information-stealing viruses that wanted to keep pouring in.
Wei sent himself an encrypted email and set up a puzzle in the email to prevent this.
If the network was really invaded and the email content was intercepted, even if the other party cracked the password with force, they will definitely be confused when seeing such a puzzle.
After repelling the cyber attack, Lam knew that the other party should be the one who forced Wei to hide, but it was too late to find out the identity of the other party.
Now he honestly cracked the password of the third email, and then quickly found Wei.
