Meat, or high-calorie and high-protein food, can be seen as a source of human happiness from both a physical and a psychological point of view. Wang Qi, who had eaten heartily, returned to his room and burped happily.

Zhen Xianzi just can't get used to seeing this kid's appearance: "What have you become, and my ring, a good immortal weapon will be ruined by you." ”

Wang Qi picked up a piece of scratch paper casually and rubbed it on the jade ring "mathematics": "I did meet something good today, I'm happy." ”

"When people don't invite you, you don't want to be happy. Zhen Xianzi sighed: "People are crazy!"

After wiping the ring clean, Wang Qi fell up and prepared for bed. But he lay down for a long time and did not fall asleep.

I'm still so excited.

Wang Qi got up from the bed. Anyway, the cultivator didn't have any need for sleep, so he just found something to do well.

With this in mind, Wang Qi looked at the source where he couldn't sleep—the storage bag he had taken from the Shenjing treasury.

"Anyway, there are a lot of things in the storage bag right now, so let's try to play with them first. ”

The first thing Wang Qi took out from the storage bag was a bottle of reagent. This bottle of reagent is contained in a clear glass bottle, and it is only a few tens of milliliters. Unlike reagents on Earth, this glass bottle flatters two layers, and between the two layers of glass is a vacuum. Then the mouth of the bottle is also engraved with a special magic seal to prevent the aura from pouring in. This is a standard bottle of Yuan Reiki reagent, which can eliminate the interference of Reiki on the real yàn as much as possible.

Wang Qi played with the reagent bottle for a while, and then put it back in the storage bag. Such a bottle of reagent is worth five stones of spiritual energy, considering that he has recently dried up some spiritual pools, Wang Qi still thinks it is better not to play with this.

What's more, he was engaged in theoretical physics in his previous life, and this vein was mostly hand-wrecked and practical.

And to be honest, there are not many harmless things like glucose in biological reagents, more of them are poisonous, and a few are highly toxic. Wang Qi's body is strong, and he is not very afraid of poison, but it is not impossible for several unknown solutions to be mixed together to make something that can poison the monk. The reagent management guidelines in the real room should be followed.

After putting away the bottle, Wang Qi took out a piece of jade and a piece of Yao Tie in his hand: "Let's come to refine the calculator tonight and try my hand." ”

The refining calculator is not a DIY assembly machine, but it is equivalent to buying electronic components to solder the motherboard by yourself, and starting from scratch. This is a difficulty for China's future IT leaders in the first decade of the twentieth century to disassemble the original from scrapped electrical appliances and make their own computers.

"Think about it, theoretically speaking, the most important thing in refining a calculator is refining yin and yang, and yin and yang are to the calculator what a logical operation unit is to a computer...... Then, the mechanism of yin and yang is the "Judgment Sutra", and the calculator is actually the same anomaly as the "Judgment Sutra...... Refining yin and yang requires a material that has both positive and negative properties......"

Wang Qi muttered to the discretion on the ground, as if he was conceiving. Zhen Xianzi sighed: "The old man saw the day when you refined the weapon alone, and the first time you refined the weapon was something that the old man couldn't understand......

However, a quarter of an hour passed.

However, half an hour passed.

Wang Qi was still meditating.

Zhen Xianzi called: "Hey, boy, it takes so long to think about practicing a hand?"

Wang Qi raised his head, his face stern: "Hey, old man, I found a problem with Yan zhòng." ”

"What?"

"What's the first step?"

Zhen Yanzi roared: "You've been thinking about feelings for so long, but you actually can't start at all?"

Wang Qi felt quite innocent: "I didn't choose a cultivator, it's not a compulsory test." ”

"Wait a minute, what about the basic theory course of refining weapons? This is compulsory?"

Wang Qi scratched the back of his head: "The basic theory of refining weapons...... Oh, this one, this is compulsory but not within the scope of the exam, at that time I remembered that I was, I was, oh, to solve the problem of the conflict between the inner law of the body, and I didn't care about listening to the class. ”

"I don't take the test because it's not something that must be mastered for seeking the Tao, but it's a necessary skill for cultivating immortals, you stupid!" Zhen Yanzi scolded: "Taking a bath is not a necessary thing for traveling thousands of miles, but what will happen if you really don't take a bath all the way?"

Wang Qi corrected: "Taking a bath will be for the sake of health, and it is easy to get sick if you don't take a bath, and it seems that it is necessary to take a bath outside the industry......"

Okay, I'm going to make up for the knowledge of the refiner......

Wang Qi sighed, put away the materials, and sat down at the desk.

I can't refine the weapon, so I'd better write my thesis.

Wang Qi took out a piece of scratch paper, thought about it, and wrote down the title of the paper - "A Little Discussion on Bo's Law of Large Numbers".

Bo's law of large numbers, known on Earth as Bernoulli's law of large numbers, is the first limit law of probability theory in history. Its core idea is very simple. The more repeated a random result is, the closer the frequency of a certain outcome is to its probability. When the number of trials is large enough, the frequency of the event can be replaced by the probability of the event.

"Bernoulli's law of large numbers is a special case of Chebyshev's law of large numbers, and Poisson's law of large numbers is a generalization of Bernoulli's law of large numbers...... This time, I'd better choose Poisson's law of large numbers......"

Poisson's law of large numbers also has some weight in the history of mathematics, but it is not as dominant as Chebyshev or Markov. In addition, it is only one step further than Bernoulli's law of large numbers. Bernoulli's law of large numbers proves the stability of the frequency of events in randomized trials repeated under exactly the same conditions, while Poisson's theorem states that the frequency remains stable when the conditions of the independently conducted randomized trials change.

Watching Wang Qi write down a bunch of things on the paper that he could read but couldn't read, Zhen Yanzi sighed: "Sometimes I really don't understand what you guys think, things that can be guessed by instinct, you have to be entangled......

"Intuition doesn't ask for the way. Wang Qi said as he wrote: "Moreover, the law of large numbers is the proof that my generation is on the right path. ”

The law that humans have in their possession is only the statistical average of the occurrence of random events, but one can know the "frequency" of random events based on the mathematical expectations, variance, and random distribution forms and parameters derived from this statistic. As humans observe more events, the closer the "frequency" gets to the "ideal probability".

That is the "Tao".

After Wang Qi had written half a page, he suddenly stopped and put aside the part he had written.

"What's wrong?"

"I'm going to take out the rest of the part and discuss it. ”

That's how Wang Qi replied. He is a newcomer, and it is really normal that the papers sent out are not taken seriously. If he is not taken seriously, it means that no one will look at him, it means that he will not get merit, and it also means that he will not be able to brush up his prestige. At this time, it is still a wise choice to tie Bo Xiaoya, who was born into a famous family, with himself. And he just graduated from the Immortal Academy, and he has "taken a small step forward, a big step forward" in the field of probability theory, which is a bit abnormal no matter how you say it. But Bo Xiaoya is different. She is good at the sword of large numbers, and has a deep understanding of the law of large numbers of the Bo family, and it seems normal to send them together in the name of the two of them.

"So, what's next?"
