MTL - Into Unscientific-Chapter 21 tough first step

  Chapter 21 The Difficult First Step

  Although Xiao Niu's sleeping style is really not good, the snoring sound is comparable to that of the ears.

  But perhaps because he was too tired from working all day, Xu Yun finally fell asleep in a drowsy state.

   Nothing to say all night.

   After an unknown amount of time, there was a burst of birdsong outside the window.

  Xu Yun lazily opened his eyes, scratched his messy hair, stretched, yawned, and just woke up.

  It is now winter in the British Peninsula, and the air in the morning is extremely humid and cold. Xu Yun exhaled in one breath, and soon a cloud of white mist appeared in front of him.

   Then he suddenly thought of something, and turned his head to look to the right.

   There was no one on Maverick's bed, obviously the patriarch had been awake for a long time.

  The sky at this time is slightly bright, and it is estimated that it may be around 6:30 in the morning, at most 7:00.

  Stay in the mainland, maybe some street writers who stayed up late to code have just gone to bed at this time.

Then Xu Yun clasped his hands together, breathed out in front of his mouth, rubbed his face vigorously, and quickly got out of the quilt—everyone in the migrant workers knows that if they want to get out of the seal of the quilt in winter, they have to take advantage of it. If you don't pay attention to the quilt, it will be done overnight.

   After arranging his clothes briefly, Xu Yun gently opened the bedroom door and looked out with his head sideways.

as predicted.

  At this time, Mavericks was sitting on the desk outside with his head lowered, writing vigorously, as if he was calculating something.

  Hearing the movement of the bedroom door, Maverick raised his head, and pouted his chin towards a tea table at the entrance:

   "The bread is on the table, it's still a piece, take a break after breakfast, and then go to inspect the orchard."

   Maverick hesitated for a while after speaking, and changed his words before Xu Yun answered:

   "Forget it, today is your first day doing this job, I will take you through the process first, and you will go alone tomorrow."

  Xu Yun nodded:

   "Understood, Mr. Newton."

   After speaking, he glanced at the Maverick who was wielding a pen, and continued:

   "Mr. Newton, I want to go out and get some water to moisten my throat. After sleeping all night, my mouth is a little thirsty."

   Maverick didn't speak this time, but hummed lightly.

   After getting permission, an inexplicable brilliance flashed in Xu Yun's eyes, and he went out with a wooden cup planed yesterday.

   There is a slightly old water tank on the side of the garden room. Judging from the age, it should be written by William, and it is located out of sight of the window behind the calf.

  Xu Yun came to the water tank leisurely, took a sip of water from a wooden cup, and poured it into his mouth without feeling too cold.

  Gulping and gargling.

   I have to say that in the context of the time before the 19th century, the mainstream cultural habits of China were much better than those of Europe.

  For example, although there was no toothbrush in ancient China, there were many ways to wash.

  For example, there is a record in "Book of Rites" that "chicken just crows, rinse with salt". In ancient China, the commonly used toiletries included wine, vinegar, salt water, tea, etc.

   Among them, wine, vinegar, and salt water have a bactericidal effect, and tea is rich in fluorine.

  The fluorine element has a certain anti-caries effect, and it can also clean the oral cavity and protect the teeth.

   Later, the famous wicker and bristle, etc. were derived, which were regarded as the prototype of the early toothbrush.

  But ancient Europe was different. They basically didn't know how to brush their teeth and take a bath-especially Britain.

   Even now, many British people still do not have the habit of brushing their teeth, so oral health in the UK has always been a big problem.

Of course.

   This is mainly related to their political and cultural background, and this matter will not be shown for the time being.

  In short, from the perspective of a modern person, Xu Yun would be happy to respect some customs if they don’t have much influence, but he still can’t get along with the custom of not brushing his teeth or washing his face.

  So he can only seize every opportunity and try to keep his body clean.

   If there is a chance, it is also necessary to correct the habits of the Mavericks and William.

  Although there is no direct evidence from later generations to show that there is any causal relationship between their lifespan and not bathing or brushing their teeth, the correction of this habit is beneficial and harmless, and it is profitable to live a few more months, right?

  After simply rinsing his mouth, Xu Yun dipped in some cold water.

   Patted on the face a few times.

  The cool feeling infiltrated the skin, making him refreshed all of a sudden.

   After washing up, Xu Yun did not rush back, but looked up at the sky.

   "Tsk tsk, it's cloudless and the sun is shining. It's really a good day for fishing."

  Xu Yun rubbed his hands together, and chose a corner of the wall where the sunlight and the shadows accounted for half.

  Take off your own 900-degree eyes, and then.

  I didn't do anything, I pricked up my ears and listened carefully to the movement at the door of the garden room.

   Meanwhile, inside the house.

  At this moment, Xiao Niu is quickly doing calculations on paper:

A+B)m/n=(P+PQ)m/n=Pm/n+(m/n)·AQ+[(m-n)/2n]·BQ)+[(m-2n)/3n]) +[(m-3n)/4n])+...."

   "Well, if it is written as e^(n*ln(1+1/n)), 0/0 is used in the exponent to convert it into 1. Damn it, it's not right!"

   Following the pause of the pen nib, Maverick plucked his hair in frustration.

   His cheeks bulged, and he let out a foul breath.

   At this time yesterday, he met Xu Yun who fell from the sky, and a series of subsequent things happened.

  Actually, this matter itself is nothing special, it’s nothing more than a relatively coincidental encounter, and that’s all it is.

  But the scene where Xu Yun landed vaguely overlapped with a certain question Maverick had thought of earlier:

  Why do things that lose their support not float up, but fall?

Of course.

   It was far from yesterday that this question really appeared. The first person who raised this idea was not even Mavericks himself.

  But Xu Yun's appearance made this question a lot deeper in Maverick's mind.

   And unlike the others.

   For this mysterious 'force', the Mavericks actually already have some clues, that is Kepler's three laws.

  According to Kepler's three laws, all planets in the solar system are moving around the sun along elliptical orbits.

  So many people, including Mavericks, guessed that there should be some connection between the inverse square law and Kepler's three laws.

But the problem is that in order to realize the mutual push between the two, it is necessary to use a mathematical tool that does not yet exist. Mavericks calls this tool flow counting, which is a kind of relationship between known flows. Relationships and methods for inverse operations.

  Now Mavericks has completed a small part of the derivation, but is stuck on the problem of simplifying the binomial (P+PQ)^m/n.

   This is his sixth attempt to simplify the binomial, but he still cannot successfully expand it into a series.

  If even this level cannot be cleared, how can we talk about analyzing that mysterious 'force'?

   So for a while, Mavericks became a little irritable, and his mind gradually began to broaden:

   In a few hours we will be leaving for Uncle William's house.

  I miss you so much, Lisa

   I don’t know how much food my uncle’s family still has, after all, there is an extra ration for a fat fish.

and many more!

   Thinking about it, Mavericks suddenly realized something, and quickly turned his head a few times:

  What about the fat fish?

   It has been more than half an hour since he went out to fetch water, no matter what, he should fetch water and come back—that kid can't go to the Thames River to fetch water, right?

  Thinking of the living expenses agreed between the Oriental and himself, Mavericks couldn't sit still.

  So he quickly put down his pen and walked out of the room quickly.

   crunch—

   After pushing open the door, Maverick walked towards the water tank familiarly.

   Unexpectedly, as soon as he turned the corner, he saw Xu Yun squatting on the ground in an Asian squatting posture with glasses in one hand.

  Finding that Xu Yun did not have an accident as he had imagined, and even showed some signs of fishing, Maverick's violent temper immediately surged:

   "FU"

   As a result, before a certain word could be uttered, he stopped it abruptly in his throat.

   It is not the review system of the Qidian Chinese website that stops him from pronouncing, but

  On the shadow of the corner behind Xu Yun, a cluster of small but clearly visible

  Seven colors of light!

   Sure enough, I caught a cold
