The human incarnation of Nyarlathotep is usually a man with dark skin, tall and thin body, and a hearty smile.

As the incarnation of Nayako in the human world, Okukankai started...tutoring after returning to school.

Well, yes, tutoring.

Because Nayako...oh, Okukankai's memory has undergone very strange changes, so his knowledge structure must be re-mastered.

It’s not just a university of knowledge.

From elementary school to junior high school, to high school, and then to college, these are all things you need to know.

Of course, Obama's tutoring is private. To the outside world, Obama is still living in the ICU.

Originally there were still people discussing this matter, but with the full spread of iBooks, the things students discussed began to change.

As the spring semester begins, the district's roughly 50,000 students find themselves learning courses like middle school history or high school biology from a new set of digital textbooks.

All the bells and whistles of these Apple-branded iBooks: videos, virtual labs, downloadable content.

Well, Catherine actually wanted to call this thing an "iPad", but considering that there might be such a tablet in the future, she just let it go.

ibook is definitely the most respected product now.

This thing has the support of the Discovery Channel, the Ivy League, and most importantly, the Second School District.

Katherine's Discovery Channel is also selling educational video services to school districts. It entered the digital textbook market largely because it saw a growth opportunity that it couldn't miss - this company, Katherine basically belongs to the free-range type. The employees who work in it

It has a lot of authority. Except for Tiantian Food...er...wilderness survival, almost all the programs here are arranged by Discovery Channel itself.

And they got in here because, according to the Association of American Publishers, traditional textbooks for kindergarten through 12th grade are a $3 billion business in the United States, and another $4 billion is spent on teacher guides.

, examination resources and reference materials.

Of course, Apple's recruitment of these companies has also allowed others to see business opportunities.

For example, Pearson, McGrawhill and Houghton Mifflin Harcourt are all launching their own digital education products, but unfortunately, only Catherine has them.

The core digital technology.

Using fed display technology, the product can be very thin and light, and because the current network is very simple and only needs the function of e-books, the current product does not consume much CPU.

The only drawback is... the battery.

No matter when, energy storage equipment always gives people a headache.

Just like on ibook.

Because of this, the ibook is made very thin and light - because there is no battery at all in this thing.

Of course, although there is no battery, it is replaced by a retractable power supply with a buckle.

In the future, such special sockets will be installed in every corner of the school district.

And because Catherine's Second School District is her home field, this thing has been installed here easily.

First of all, it goes without saying that schools have such equipment on every desk in every classroom.

On the streets, there are also such devices on benches, in squares, and on restaurant seats.

Relying on this device, students can read almost anywhere and anytime - of course. Only in the second school district.

This is forcibly promoted by relying on the strong execution power of Ark Group, but on the other hand, it has to be said that this is also a kind of helplessness...

Of course, none of this has anything to do with Obama. At this time, Obama is still tutoring.

"It seems like he's quite adaptable now."

After observing it for a while, Catherine was full of satisfaction.

"Although this person is still the same Obama, I feel that there is a big difference between him and the real, original Obama."

Jenny responded to Catherine.

"Is that so?"

Catherine tilted her head.

"Okay, now it's time for me to continue my research. The progress of the Human Genome Project has exceeded 80%. I may be able to take a look at these materials."

"What are you looking at?"

Genes are a very magical thing. When Catherine found Jenny reading a paper, she also put her head close to it.

"Epigenetic variation (heritable trait changes that do not involve modifications to the DNA sequence) injects Heisenbergian uncertainty into gene expression, which can give a species a better chance of surviving... well..."

Is this a magical thing?

"Mr. Dawkins' latest paper. "The Uncertainty Principle of Evolution."

"..."

Catherine burst into tears.

Coach, I want to study biology!

"Simply put, biology has a built-in random mechanism to prevent all eggs from being put in one basket. For example, a body that easily accumulates fat can help people survive famine but is not good for health. If good days continue for many

Generations, natural selection will eliminate the fat gene from the entire race. And when famine finally comes, the race may become extinct. But if there is a mechanism that allows some people to accumulate the same genes as others, it will be easier

fat, so they could perpetuate the race in times of famine."

Jenny's explanation is much easier to understand than Hayfrick's bible-like explanation.

"Lamarck once proposed that acquired traits can be passed on to the next generation. Darwin also believed that acquired changes provide options for natural selection - although DNA later gave up acquired inheritance, but a recent one

Since the beginning of the century, people have re-recognized that environmental factors can cause heritable variation in organisms. Many different mechanisms of epigenetic inheritance, such as DNA methylation, have also been discovered."

Myopia is an acquired change, but this change is absolutely not hereditary. To say that myopia is hereditary is absolute pseudoscience.

"Dr. Dawkins's paper is excellent and his indeterminate hypothesis points to another role for epigenetic inheritance."

Seemingly seeing that Catherine didn't understand, Jenny went on to explain: "In the study of DNA methylation, he and his colleagues found that different individuals, and even different cells of the same individual, have different DNA methylation patterns. What's more, it's even more surprising.

Surprisingly, those genes that are significantly affected by methylation are important genes that control the basic development of the body. This means that epigenetic changes can bring significant changes to the phenotype."

"If Dr. Dawkins is correct, evolution is selecting not for epigenetic traits but for the very mechanisms that produce epigenetic diversity."

Catherine nodded doubtfully.

She decisively chose to change the topic.

"Speaking of DNA, maybe compared to hard drives, DNA seems to be a good way to store our technology, right?"

"I don't know much about things on hard drives, but if it's a relatively simple theory...well...I think it's probably OK."

Using DNA to store data is no longer an impossible task in the 21st century.

In the 21st century, Harvard University stored 700 terabytes of data into just 1 gram of DNA.

In the laboratory environment at that time, people used this method to store more than 100 million hours of high-resolution video, and only needed a small cup of DNA.

"Reading DNA is simple, but writing data accurately remains a major obstacle to realizing DNA storage."

Jenny thought for a moment and then said: "Moreover, using the current method, we can only create a small piece of DNA; secondly, the reading and writing of DNA are very error-prone, especially when a large number of the same characters are encoded into DNA."

"If the code is divided into several overlapping fragments in two directions, each of them is equipped with index information, which can show which section of the entire code each fragment belongs to. In this way, a code is designed that does not allow duplication

Method. Using this method, the data will only fail to be read if the same error occurs on the four fragments. In this way, maybe it is feasible?"

Catherine put forward her own opinion. After all, she was born in software.

A similar method was actually used in the 21st century: Agilent Technologies in California provided synthesis equipment for researchers. Ivan and Nick sent a piece of DNA-encoded data to Agilent, including a Martin.

A highly fault-tolerant coding method has been created in molecular form (i.e. DNA), and this storage method can be stored for 10,000 years or even longer under the right conditions. As long as someone knows what these codes are, and one

If they have a machine that can read DNA, they can know its contents.

This is absolutely amazing technology.

This high density and durability of DNA make it a very attractive storage medium.

Tapes are declining more and more nowadays, and the space of hard disks is increasing too slowly. Fluorescent discs are stuck in technology. Now, Catherine thinks that maybe DNA hard disk is the best way?

…

Four updates completed! There is one more update to go! The human incarnation of Nyarlathotep is usually a man with dark skin, tall and thin body, and a hearty smile.

First of all, there is no need to talk about schools. There is such a device on every desk in every classroom.

On the streets, there are also such devices on benches, in squares, and on restaurant seats.

Relying on this kind of equipment, students can read almost anytime, anywhere -of course, only in the second school district.

This is forcibly promoted by the powerful execution of the Ark Group, but on the other hand, it has to be said to be helpless ...

Of course, these have nothing to do with Obama. At this time, Obama is still tutoring.

"It seems that he is quite suitable now."

After observing for a while, Catherine was full of satisfaction.

"Although this person is still the previous Obama, I think there is a big difference between him and the original Obama."

Jenny responded to Catherine.

"Will this be like this?"

Catherine crooked his head.

"Well, now I should continue to study that the progress of the human genome program has exceeded 80%. I may be able to see these materials."

"What are you looking at?"

This thing is amazing. When Catherine found that Jenny read a paper, she also made her head.

"Objective genetic variation (genetic changes in genetic but not involved the modification of the DNA sequence) injected the uncertainty of the Heisenburg style into gene expression, which allows species to have more opportunities to survive ... uh ..."

Is this a god horse?

"Mr. Doukins's latest paper." Principles of uncertainty of evolution "."

"..."

Catherine burst into tears.

Coach, I think students!

"Simply put, there is a built -in random mechanism of creatures to prevent all eggs from being placed in a basket. For example, the constitution that is easy to accumulates fat helps people to spend the famine but it is not good for health. If a good day continues to be more

On behalf of the natural choice, the fat gene will be removed in the entire race. When the famine finally comes, the race may be extinct. But if there is a mechanism for some people to have the same genes as others, it will easily accumulate

Fat, then they can continue the race during the famine period. "

Jenny's explanation is better than Hayfrik's natural script, so people must know much.

"Ramak has proposed that the traits obtained the day after tomorrow can be inherited to the next generation. And Darwin also believes that the acquisition of nature has provided an option for nature to choose.

Since the century, people have re -realized that environmental factors can lead to genetic variations that can produce genetic variants. Various mechanisms that are inherited, such as DNA methylation have also been discovered. "

Myopia is a kind of obtaining change, but this change is absolutely not inherited. It is said that myopia will be inherited, which is an absolutely right pseudo -science.

"Dr. Doukins's paper is very good. His uncertain hypothesis points out another role of apparently inheritance."

It seems that Catherine does not understand. Jenny then explained: "He and his colleagues found different individuals, even different cells of the same individual in the study of DNA methylation.

It is surprising that those genes that are obviously affected by methylation are important genes that control the basic development of the body. This means that apparent genetic variations will bring significant changes to the expression. "

"If Dr. Doukins is correct, the evolution is not selected by the apparent genetic traits, but the mechanism itself that produces an apparent genetic diversity."

Catherine nodded in doubt.

She decisively chose the topic.

"If you say DNA, maybe for the hard disk, DNA is used to store our technology, it seems to be a good aspect?"

"I don't know about things on the hard disk, but if it is a relatively simple theory ... oh ... I think it's okay."

Storing data with DNA. This is a task that is not possible in the 21st century.

In the 21st century, Harvard University deposited 700TB of data into only 1 gram of DNA.

At that time, the laboratory environment, people used this method to store high -resolution videos of more than 100 million hours, just a small cup of DNA.

"The work of reading DNA is simple, but how to accurately write data is still the main obstacle to achieve DNA storage."

Jenny thought about it. Then he said: "And, in the current method, we can only create a small section of DNA; second, the reading and writing of DNA is very easy to make mistakes, especially when a large number of the same characters are encoded into DNA."

"If the encoding is separated into several overlapping fragments in two directions, each is equipped with indexing information. This can show which section of each fragment belongs to the entire code, so that a coding that is not allowed to repeat repeated codes can be designed.

Methods. Using this method, the data will fail to read the same errors on the four fragments. This method may be feasible? "

Catherine put forward her own view, after all, she was born with software.

Similar methods, in fact, the original 21st century was applied: Agaren Technology Company in California provided researchers with synthetic devices. Ivan and Nick sent a section of DNA data to Aglen, including a Martin.

In the form of molecular (ie DNA), a method of encoding with high tolerance capabilities can be created, and this storage method can be stored for 10,000 years or even longer under the right conditions.

Taiwan can read the DNA machine, and they can know the content.

This is definitely a great technology.

This high density and persistence of DNA make it a very attractive storage medium.

The tape is becoming more and more declining today, and the rising space of the hard disk is really too slow. The fluorescent disc is the owner of the craft card. Now, Catherine thinks that maybe the DNA hard disk is the best way?
