Into Unscientific Chapter 180

  Chapter 180 Now everything is engraved into DNA (6.241K)

  Outside.

   With the drizzle falling.

  Many events that would have developed in another direction have quietly appeared an inflection point.

  These things are big or small, light or heavy.

   Among them are national strategic plans, small businesses of ordinary people, and trivial bickering of ordinary people in the market.

   This drizzle is like a broom.

  Swept away all the hostile garbage in the society, and silently changed the life trajectory of countless people.

  And when these inflection points of countless quantitative changes are added together, some qualitative changes will naturally follow.

Of course.

  This qualitative change cannot be seen, cannot be touched, and can take a long, long time to actually see results.

  From those in power to ordinary people, at most they feel that many things seem to be going smoothly than expected, that's all.

   Therefore, Xu Yun, who is in a claustrophobic space, naturally cannot know these changes.

  He can only guess from the literal meaning. This is probably a buff similar to blessing, and it is also a common effect in the game.

  But he doesn't understand the effect of this so-called +1.

   Then he temporarily put his curiosity aside, and returned his attention to the ball.

  He had already dropped four small **** before.

   A time album, a formula card without any explanation, an easter egg and a buff were issued respectively.

  Although these rewards have their own characteristics, their value is not low.

   But neither appears to be a realistic technology for imidacloprid-like formulations.

   I wonder if there will be other black technologies in the next four balls?

  Think here.

  Xu Yun couldn't help stretching out his hand, and poked at the fifth bubble.

  boo~

   After a while.

   Another piece of paper floated in front of Xu Yun.

  He subconsciously took the piece of paper.

  The texture of this piece of paper is very soft, only the size of a Band-Aid, and the content on it is also very simple, with only one landmark written on it:

  Longitude:117.2764

  Latitude:31.8392

  【Hint: This is a coordinate, guess what you will find? 】

  Xu Yun frowned suddenly.

  Although his major is science, he has no intersection with geography, and he has not had much contact with latitude and longitude information in his spare time.

  But as a HKUST student for two lifetimes, he still has some impressions of this number:

  Ignore the last few digits, just look at the first five numbers, isn't this the HKUST campus?

   As for where the last three digits are, it's hard to say, but it must be on the HKUST campus.

  USTC campus. What will there be?

   There will never be cockroaches, right?

   besides

  What should I do if it is a female dormitory?

  Holding this delicate mood, Xu Yun put away the paper and continued to click on the sixth light sphere.

  boo~

  The moment he saw the photosphere evolution, his brows were raised slightly:

  The sixth light sphere is still a small piece of paper, but he is somewhat familiar with this piece of paper:

  The paper sheet engraved with the formula of the fifth-generation imidacloprid was of this material and specification.

as predicted.

  When the piece of paper falls into the hand.

  Xu Yun spread it out on the palm of his hand, only to see a line written on it:

  [DNA storage technology: This is a very interesting technology, but it also requires a little bit of effort to research, are you ready, young man? 】

  【Comment: Don't carve everything into your DNA, Hundan, except Fenghualian's out-of-print video before she retired. 】

   "Hey guys, DNA storage technology?"

  As a biological Wang, Xu Yun has a good understanding of cutting-edge biological technology in his life.

  In the current cutting-edge field of biology.

  DNA storage technology has always been a project that is not widely spread, but it is recognized as a promising project.

  The theoretical basis for this technique is simple:

first.

  Current computer data is stored with 0 and 1, that is, binary.

  And the students who are not mad at the biology teacher should know it.

  Every bit of DNA has only four possibilities:

  AGCT.

  If the bases are assigned, such as T=0, G+C=1, then chemical signals can be converted into digital signals.

  Therefore, a DNA can be regarded as a binary data storage material.

  As for why DNA is used as a data storage material?

  The reason is also very simple.

  The amount of information produced by the earth every day has far exceeded the sum of information in the evolution history of human civilization in the past 5,000 years (Source: International Data Corporation).

   This is also the origin of the term big data era.

  Estimated based on current trends.

  In the next year alone, a data volume of 48ZB (1ZB=10^12GB) will be generated.

   Wait until 2040.

  The world needs at least one million tons of silicon-based chips to store the data generated that year.

  So, someone is targeting DNA.

   Technically speaking.

  In addition to binary effects, DNA can be artificially synthesized from scratch, which can be achieved by solid-phase synthesizers.

   In addition, DNA can also be amplified in large quantities in the laboratory by PCR technology.

   This ensures that a large amount of DNA with the desired sequence can be easily synthesized.

   As for the advantages of using DNA for information storage

   Naturally, it has high storage density, low energy consumption, and long storage period.

  For example, the storage density of DNA can reach 10^19bit/cm3, which means that theoretically only one kilogram of DNA is needed to store the current total amount of global information.

   In 2012.

  Penn University's Church and others used DNA synthesis technology to store a book, including 53426 words, 11 pictures and 1 JavaScript program, a total of 5.27MB.

   Subsequently, they stored a dynamic gif information into DNA, which can be introduced into E. coli for self-replication.

  It was last year, which is 2021.

  The local team of Southeast University successfully stored the four Chinese characters of the school motto "Zhi Zhi Shan" into a DNA sequence, and this matter was also listed on SCIENCE ADVANCES. (DOI: 10.1126/sciadv.abk0100)

But on the other hand.

  Although this technology is more promising, it has great limitations.

   The first is the cost.

  Generally speaking.

  The base AGCT of DNA costs 0.5-1 US dollars, which is 3-6 Huaxia coins.

  Because the "consumables" are too expensive, it is difficult for both experiments and civilian popularization.

  The second is the problem of reading.

  At present, it takes an average of several months to store a movie, which is much longer than the computer hardware cycle.

   At the forefront of the entire technology is the team led by Erlich of Yale University. Not long ago, they coded an operating system called movie1.

   Not only can this system run smoothly, it can even play minesweeper.

all in all.

  This is not a technology that appeared out of thin air. It has a certain foundation and possibility of finished products, and it is relatively not so difficult in terms of acceptance.

   Predictably though.

   Just like the threshold of the fourth generation in addition to the formula of the fifth generation imidacloprid.

   The DNA storage technology given by Halo may still require a lot of research and development to achieve results.

at the same time,

   There was also an inexplicable emotion in Xu Yun's heart.

  He always felt that this technology seemed to be prepared for other things.

  But after thinking about it, he finally couldn't figure out what it had to do with it, so he could only temporarily put this thought behind him.

  Maybe it's just my own random thinking

   anyway.

  This DNA storage technology is also the only physical technology he has obtained so far.

  The previous equations and landmarks are at most only the possibility of certain technical realization, and cannot be regarded as guaranteed formulas.

   Then Xu Yun adjusted his breathing, and cast his gaze on the last two light spheres.

  What will appear in them?

soon.

  boo~

   This time.

   What appeared in front of Xu Yun was still a piece of paper that was exactly the same as the DNA storage technology.

  Technical reward two combos.JPG.

   After getting the piece of paper.

  Xu Yun skillfully turned the piece of paper over, and when he saw the information written on it, he was slightly taken aback:

   "Good guy, what is this thing?"

  I saw a few words on the piece of paper:

  【Artificial intelligence-entry version-upgradeable】

  【Evaluation: An artificial mentally retarded person who is much dumber than Xiao Ai, but as long as you can become a long-distance runner, you may see it upgrade one day! 】

  Xu Yun:

be honest.

  After going through two missions, he has somewhat understood the personality of the halo, or made some preparations.

  So what silenced him was not the halo words, but the nature of the reward:

  The technical rewards that appear this time can be attributed to physics, computers, and even mathematics.

  But it's the only one that doesn't have much to do with creatures.

   So does this illustrate one thing:

  The rewards given by the halo are not just technology or knowledge in the biological field?

  If so.

  The actual value and influence that the halo may produce will be much higher than Xu Yun's original expectation.

   After all, from the perspective of life research, biology and chemistry must be key subjects.

   But from a technical point of view, physics and mathematics are the real core subjects.

   It would be interesting if the aura rewards included other rewards.

To know.

  Old Su's mission is only four stars.

   Not to mention there is also a comparison link to complete the scoring.

  If you get a high ratio score in the five-star mission, what will the reward be?

  Controllable nuclear fusion?

  Anti-gravity technology?

   Or an automatic code word keyboard?

  Endless possibilities

  With such a comparison, the artificial retardation reward itself is not so eye-catching.

  After all, the entry version and subsequent evaluations can explain everything.

  If you want to upgrade this thing, I'm afraid you need to complete a few more tasks.

  From the perspective of ability realization, its ranking may be lower than DNA storage technology.

Of course.

   Considering the four words of artificial intelligence in the official name.

  The value of this reward after realization is obviously far beyond what DNA storage technology can compare, and it is worthy of its penultimate photosphere ranking from the perspective of value.

  As for the penultimate one, we have to mention the penultimate one—or in other words, the only light sphere left.

   Then Xu Yun took a deep breath, put away the small piece of paper,

  Looked at the eighth light sphere.

   I don't know if it's because of my mentality.

  He always felt that this ball of light seemed to be a little larger than the other seven in terms of volume, similar to the situation of eggs and goose eggs.

   Then he was silent for a moment, and stretched out his finger towards the finale ball of light.

Snapped-

  The eighth light sphere issued a distinctive broken syllable.

   After a while.

   A beam of golden particles slowly floated out of the light sphere.

  This beam of particles neither flies to the halo like the time-space album, nor does it appear as a piece of paper or a golden egg like other rewards, but

   Slowly flew around in the space, and finally disappeared abruptly.

  Xu Yun:

   Could it be another buff similar to a big tripod?

   Not right.

  Although the great cauldron of the National Games disappeared from the space in the end, it still had some explanations before it disappeared.

   From the performance point of view

   It seems to be a combination of the shortcomings of the National Games rewards and the formula card?

  Scratching head.JPG.

  Think here.

  Xu Yun could not help but sigh slightly:

  The eight light spheres are all disassembled right now.

   Among them, Chinese luck, formula cards, and golden particle beams are all unclear things, and the origin and whereabouts cannot be seen clearly.

  Artificial intelligence is an entry-level version of mental retardation, and there should be no big expectations in the short term.

  As for the easter eggs.

   This thing may bring emotional surprises, but it will not produce too high practical value.

  Unknown what will be found at the coordinates of the University of Science and Technology, the rewards that really make Xu Yun feel "good" are actually two:

  Space-time album and DNA storage technology, the former is the first reward to be released.

   This is a bit of a crotch, is it worthy of what I have worked so hard to do?

  If this content is put in the novel I wrote in my previous life, I am afraid that it will be sprayed like a dog by readers!

  Think here.

  Xu Yun looked around again.

  The rewards that should be taken now have already been taken, and the time consumption of the time-space album has also been used up, so it is meaningless to stay in the space.

  So he thought for a moment, and decisively chose to return to reality.

   After a slight dizziness.

  Xu Yun's eyes lit up, and he returned to the long-lost cabin, standing in front of the computer desk.

  One press to turn on the phone, and the time will appear automatically.

   Same as the 1665 copy.

   Nearly a year has passed in the dungeon, but in reality it only jumped for a few seconds.

  Wear down jackets and warm boots when walking.

  When he came back, he was dressed in an ancient costume, and even his hair grew back to look like an ancient person.

at the same time.

  Xu Yun was also surprised to find one thing:

   After living in the Northern Song Dynasty for a year, he actually felt a subtle but obvious sense of separation from reality, that is, the modern technological environment of the 21st century.

  For example, the mobile phone on the table.

   When he just turned on the phone to check the time, he pressed the volume button several times before realizing that the small button below the volume button is the power button.

To know.

   Right now, it's just the second dungeon he's experienced.

  Who knows if there will be a two-year, three-year or even five-year mission period in the next mission?

  The sense of separation brought about by the switch between the two eras does take a lot of time to get used to.

   Use an idiom to describe it.

   It seems like a lifetime away.

   Perhaps next time before entering the copy, you can prepare a memo on the table first?

   Look through the memo when you come back, maybe you can recall the reality faster, and at the same time avoid some psychological problems.

  When he was writing a novel in his previous life, he had read a book called "Global Movie King", in which the protagonist seemed to have some psychological problems because of this.

  For example, dressed as an old man, come back to fall in love with aunt or something.

  Thinking of this, a line of poem appeared in Xu Yun's mind:

   "Who will wake up to the big dream first."

  However, when he was still in a daze, a voice suddenly came from his ear:

   "Where is this?"

  Heard a sentence.

  Xu Yun's whole body trembled, and he subconsciously turned around.

  I saw this moment.

   At the end of the bed not far from him, stood a young man in his 20s!

  A series of possibilities such as the thief flashed across Xu Yun's mind, and he subconsciously picked up an apple knife on the table.

  Shoulders sank, he made the opening gesture of "Lai Fu Jian Jue", and asked:

"Who are you?"

"I?"

  The young man raised an inexplicable expression on his face, frowning and staring at Xu Yun for a while.

  After confirming that Xu Yun's expression was serious, he said in modern Chinese with a correct accent:

   "Old man Su Song, why, Xiao Wang, you don't recognize the old man?"

at the same time.

  A curtain of light slowly appeared in front of Xu Yun:

  【Special mission settlement reward: 22-year-old Su Song, who has complete documents, is in full bloom, and has all the memories of his previous life. Be sure to give a five-star praise! 】

  【Evaluation: Su Song in history was not well-known for various reasons. Instead of correcting people's perceptions, it is better to let him create history again! 】

   "Fuck?!"

Note:

   After finishing this chapter, I feel relieved.

   It feels like it's too early to ask everyone to rate the day before yesterday. Many readers said that I made Lao Su depressed and ended up deducting points, but Lao Su's ending is here.

  Actually, I have hinted that Lao Su will come to modern times a long time ago, and I have hinted more than once. At the beginning, it was Xu Yun's admiration when he judged the principle of the generator, and there were many similar hints later.

   And he also said during the coup that unless Lao Su really saw the original historical facts, he would not be able to let go.

  This is also the foreshadowing that I planted from the beginning. Why did the protagonist travel to the side of a mature old Su?

  How much change can a dying person make in the world?

   The answer is here.

  No matter what the dungeon history is, the old Su in the local history is still very little known. Of course, he has to change all this...

   Continue to explode tonight, ask for a monthly ticket! !
