Humans and ghosts, ghosts and humans, two completely opposite but common life forms. Ghosts come from humans, and humans will become ghosts when they die. Ghosts will be reborn and become humans again.
A reincarnation.
To be more precise, all life has a soul. When the soul loses the body as its carrier, it becomes a ghost.
There is a clear but invisible line between humans and ghosts, separating them from each other.
There is an old saying that goes, humans and ghosts have different paths.
The world of the living and the world of the dead coexist and oppose each other.
Damn it!
Yin-Yang eyes!
This should be the hidden skill of the Hermit profession. Otokogawa was sure that he would never be able to see souls before he awakened.
Of course, except for evil spirits.
I bought braised beef, chicken legs, bread, milk and of course instant noodles in the supermarket.
Traditional sauerkraut noodles, braised beef noodles, and a bowl of dry noodles.
"Well, let's just make do with what we have! Peace is still good! Spicy crayfish, grilled squid, fresh braised beef, roasted pig's trotters, just thinking about it makes me drool. If there's chaos in the future, I won't even have enough to eat, how can I enjoy the food..."
Three bowls of noodles were lined up in front of me. To be honest, they smelled pretty good.
I opened the vacuum bag of braised beef and took a bite. It was not as delicious as the freshly made ones in the braised food shop. It was not chewy enough, and the texture and taste were really disappointing.
The chicken legs are even worse, the meat is all scattered, just enough to fill your stomach.
After barely filling his stomach, Xiao Yi took a shower, changed the bed sheets, and lay on the bed, watching the 10 points of energy absorbed by the evil spirit. Tomorrow he could finally activate the skill of "entering meditation" to study "Zhou's hypothesis."
"Well, why not come now? I can't sleep anyway..."
I really couldn't sleep. I was unconscious for more than ten hours during the day. This sleep was enough.
Paper and pen are ready, and the draft of previous research is placed in front of you.
Xiao Yi closed his eyes and calmed himself down. He felt like he had entered a state and then began to enter a state of "meditation".
The basic content of Zhou's speculation is very concise:
When 2^(2^n)
Looks simple, right
Amateur scientists are unwilling to study such conjectures of domestic scholars. Their attention is focused on problems such as the Goldbach conjecture, or trying to overturn Fermat's Last Theorem which has been proven.
Zhou's conjecture
I don't even bother to pick up a pen!
For them, solving such a problem means they cannot get money because no one offers a reward, and they cannot become famous either. Even if it is reported in the news, it will not cause much response among the public.
Of course, the premise is that it can be proven.
This conjecture about Mersenne primes was proposed in 1992 and has not yet been proved or disproven. It has become a famous mathematical problem that has troubled the entire mathematical community for more than 20 years.
And it's that simple.
Regarding the distribution of Mersenne primes, British mathematician Shanks, French mathematician Trotta, German mathematician Berlihart, Indian mathematician Ramanujan and American mathematician Gillies have all made speculations. However, their speculations have one thing in common, that is, they are all proposed in the form of approximate expressions, and the degree of closeness between them and the actual situation is not satisfactory.
Only Zhou's conjecture was put forward in a precise expression, and it is quite mathematically beautiful.
There are not many conjectures and theorems named after Chinese surnames in the world. If Zhou's conjecture can be proved, there will be another Chinese seat in the hall of mathematics.
This is a great thing that will bring glory to the country and honor to the nation.
It will go down in history.
As for proving Zhou's conjecture and promoting the progress of Mersenne prime research, what is the use of it
It doesn't seem to be of any use.
The study of Mersenne primes began hundreds of years ago. Before the invention of computers, calculations were done manually. Euler once proved that 2147483647 was a prime number by mental arithmetic while blind. This is the eighth Mersenne prime number found, and it has a total of 10 digits.
This calculation...
A normal person would feel confused!
(_)…
Of course, through the unremitting efforts of later generations, precise calculation formulas were developed for finding prime numbers. Later, the treasure hunt was handed over to computers. Now that we have supercomputers, it is still not an easy task to discover Mersenne primes.
The total number of Mersenne primes discovered in the mathematical community is still within the two-digit range and does not exceed 50.
As for what is the use of this Mersenne prime
RSA algorithm (asymmetric encryption algorithm) is one of them. Every time you shop online, you have to thank the large prime number hidden in the password that cannot be disassembled. Checking computer performance is one of them. Large prime numbers can be used to detect system vulnerabilities.
The significance of mathematics cannot be measured in money.
The meaning of these numerical puzzles is, perhaps, as a mountaineer would say, because the mountain is there.
She is right there, waiting for you to discover her, to climb up, and to see the infinitely beautiful scenery at the top that no one has ever set foot on.
Some mathematical theories that seem quite mysterious and profound now may correspond to something in nature and have potential applications, but we don’t know it yet.
Pythagoras discovered the mathematical relationship between the harmony of strings and their length. Before that, tuners relied only on intuition and experience. Later, Western music developed beautiful "chords" based on the twelve-tone equal temperament.
When exploring the "Riemann prime conjecture", mathematicians Hilbert and Polya focused on the energy levels in physical systems.
People have known about pi for a long time, but few people know that the length of all rivers on Earth is roughly equal to π times the straight-line distance from the starting point to the end point. The more rivers people count, the closer the average value is to π.
Perhaps the attraction of mathematics and mathematical mysteries lies in the fact that they appear to be “useless” and are not restricted by “usefulness”.
Of course, the most intuitive manifestation of the impact of mathematics on Xiaoyi is the accumulation of experience, which is the external manifestation of the development of the brain.
Dawn came, and the sunlight shone through the windowsill and fell on Otokogawa's back and shoulders, making them look as if they were coated with a layer of gold and sparkling.
But he was unaware and was still immersed in his own world.
When a person is doing something, he devotes his whole body and soul to it and forgets everything around him. At that time, he exudes charm and he is the most charming person.
Unfortunately, no one appreciates it.
The pen in his hand kept writing very smoothly, making a rustling sound.
After nearly 4 hours of thinking, my thoughts were finally opened up. I figured out all the previous doubts and mistakes, and the problem about "Zhou's conjecture" was easily solved in my writing.
Xiao Yi gently put down the pen and rubbed his temple. He didn't prepare any brown sugar water, so he could only swallow a bag of bread with the milk.
Then he threw his heavy body onto the big bed, closed his eyes, and began to cry...
