Popular science physics, teach a magic god?

Chapter 2 Electromagnetic induction is not magic induction!

"Master Tesla!" Downs bowed excitedly again and again.

"I'm not your master yet. Also, you can just call me Renn from now on." Renn waved his hand casually.

"No! Regardless of whether the master admits it or not, you are my master - Master Tesla." Downs's kneeling was meticulous.

Don't tell me, Ren was quite happy.

Suddenly, he felt that being a science dog was not so uncomfortable anymore.

If he hadn't traveled through time, he would probably be able to earn a monthly salary of 3,000 yuan as soon as he graduated.

Ahem!

That's too far.

As a time-traveler, when it comes to accepting apprentices, the first thing he thinks of is: to get started, he must first give the teenager a nine-year compulsory education, and then thoughtfully send a box of "Five-Year College Entrance Examination and Three-Year Simulation".

But for the sake of a little money, give Towns a crash course.

Stack an armor first.

Renn reiterated again and again: "Remember! I only teach you [knowledge], whether you can learn it or not..."

Downs said firmly: "There is only one magician in ancient times. If...if I really don't have the qualifications as a disciple, I will admit it."

Renn raised his right index finger very seriously: "One semester! I will only give you one semester, which is half a year. If you can't learn..."

Downs felt awe in his heart. He couldn't help but think of the magician's apprenticeship in the bard's legend - a qualification test. If the tester does not have the qualifications, he will leave immediately. How can the master be so kind as to give him half a year.

Sure enough, Master still values me very much!

Tang Si nodded heavily and said resolutely: "If the disciple makes no progress within half a year, the disciple will leave on his own and no longer interfere with the master's cultivation."

good! Children can be fooled!

Ren finally smiled.

He didn't want to be a liar, but there were too many idiots in the other world, so he had to give him money. He just teaches physics.

Downs has studied physics but can't understand magic, so what does he have to do with Ren?

When he thought of this, Renn felt no more psychological burden.

After saying that, Ren turned around and left with his hands behind his hands. Downs immediately followed behind him: "Master, when will you teach me thunder magic?"

Ren glanced at the sky: "It's getting late. Let's rest for the night and talk about it in the morning. Yes, can you cook?"

"Uh, I understand."

Originally this would have been an ordinary conversation, but as Downs and Renne turned a corner and came to Renne's house, little Downs was stunned.

Downs saw an electric light for the first time in his life: "Master, this is..."

Ren was stunned.

Looking at the stupid temporary apprentice with enthusiastic eyes, Ren found that he couldn't explain himself again.

There are three treasures in time travel: cement, glass and soap.

These three things can be made by hand as long as you have enough materials and understand the principles.

Glass is composed of plant ash and sand, which are placed in a refractory container and fired at high temperature in proportion to produce a glass solution.

It happened that the blacksmith shop had tungsten, so Ren used tungsten to pull out tungsten wire, matched it with glass, and made a degraded version of the tungsten filament light cannon. He connected it to the alternating current from the waterwheel to create this flickering light cannon. Come.

Back and forth, Renne failed at least hundreds of times.

In front of the natives, this is undoubtedly magic.

Looking at the electric light on the roof of this small tiled house, Downs asked, "Master, is this also lightning?"

"It's definitely electricity!"

"Where does the electricity come from?"

Renn paused and pointed to the waterwheel not far away: "This is hydroelectric power, or [hydropower] for short."

This time, it was Towns' turn to be stunned.

One look at Downs's expression, and Ren knew that he might be in trouble, so he decisively bit him to death: "Don't think too much! This is [science] too!"

The speaker has a heart, and the listener has a heart!

"science?"

"Yes! This is an application of electricity after electromagnetic induction generates electricity."

Ren's statement was so categorical and unquestionable that it seemed to be something else in Downs' ears:

I see! Master is the kind of person who has a hard mouth but a soft heart!

He said he wouldn't accept a disciple, so why didn't he accept me as a disciple?

What he was preaching was [Science], but in fact, his magic teaching had already begun!

The master is clearly saying now - thunder and lightning are everywhere, the key is to rely on [induction]!

Master, I understand!

…

Here, seeing Downes looking excited and a little distracted, Renn was extremely embarrassed. If he knew that the [Electromagnetic Induction] in his mouth was cut into the so-called [Induction], he would probably slap this stupid apprentice to death on behalf of Nikola Tesla.

With some doubts, Ren asked: "What do you understand?"

"Induction!" Downs replied loudly.

Ren was a little unsure, but added: "Okay, I will show you the electromagnetic coil tomorrow."

Downs blinked. He doesn't understand [magnetic] and [coil], but this doesn't stop him from continuing to think about it:

tomorrow?

Doesn't this mean that Master's test has begun, and the winner will be decided tonight! ?

Downs couldn't help but feel nervous.

After starting to cook, Downs was a little distracted.

After all, his time... is running out.

As a former knight apprentice, Downs was no stranger to doing odd jobs. This is how knights come. Children follow the knights to do chores when they are very young. When the knights are free, they will teach their apprentices martial arts and the spirit of chivalry. When the apprentice grows up, he becomes a knight's retinue and follows the knight in battle.

Only by gaining recognition from the lord or becoming a professional can one be promoted to a true knight.

Tang Si quickly helped to light the fire and cook, while nervously answering Master's various questions about the outside world. Apart from anything else, Tang Si was extremely sure that the master had really been away from the world for a long time and knew nothing about the outside world.

The respect for the master in his heart deepened.

After eating, he still couldn't hold it back: "Master, what's going on with your [electromagnetic induction]?"

Lane replied casually: "First of all, you need a magnet. Magnets can produce magnetic fields. Although magnetism is invisible and intangible, it is real."

As Ren spoke, he pulled out an iron magnet and performed the magic trick of using a magnet to attract iron.

This scene became another scene in Downs' mind: Master was reminding me again that thunder and lightning existed in every corner of the world before they were seen. You can't see or touch it, but it is real! ?

Here, Lane rotated the U-shaped magnet around a bundle of small coils and said at the same time: "First form a closed [circuit], and then, as long as the magnet rotates fast enough, electricity can be generated through changes in the magnetic field. "

Downs' eyes widened: Oh! What Master is saying is that I want to become some kind of 'magnet', spinning rapidly and attracting the electricity hidden around me. As long as my magnet rotates fast enough, electricity can be generated that is visible to the naked eye.

Renn saw that Downs was looking a little bewildered and couldn't bear it: "Okay, okay, I'll teach you scientific knowledge tomorrow. Go to sleep first."

In the dead of night, Tang Si couldn't sleep. He tossed and turned, muttering the word "induction" from time to time.

This small tile-roofed house is only seven or eight square meters. It belongs to a half-collapsed house. It only has such a small space for two people to sleep. How could Renn not know the condition of this stupid apprentice?

There are many ways to help you fall asleep.

Maybe it's counting sheep, but in this case, another method must be used.

"Downs, don't think too much, clear your head. Go to sleep!"

The words that came from the master made Tang Si suddenly jump into action.

Master never talks nonsense, and every word he speaks must have a profound and mysterious meaning. Even at this time, Master is still guiding me!

Short?

correct!

I was so nervous that my mind was filled with the word "sensing", but I couldn't sense anything.

I should follow the teacher's instructions, empty my mind, don't think about anything, and sense the external situation.

Everything was silent in the distance, neither the sound of insects nor the chirping of birds.

There was only faint thunder in the sky and the roar of wind.

In addition to the beating of his own heart, there was a sound beyond sound.
