Chapter 1715 Gretel: Teacher, Please Work Harder and Become Einstein! (Ten Thousand Rewards Plus Update 21)

"How did you understand today's lecture?"

Grete was gesticulating with the magicians, frothing at the mouth, making many requests, checking their plans, and supervising their progress. Then he was lying on the table writing and drawing, recording every fragment of his inspiration. .

Suddenly, a tepid question came from behind him, which shocked him so much that he jumped up on the spot and almost dropped the pen in his hand:

"Old...teacher!"

"Huh? What are you writing? - Let me see it." The Lord of Thunder stretched out his hand as a matter of course. Gretel was respectful, holding the record book in both hands, standing sideways and staring at the teacher's face:

I didn't write anything, did I?

You didn’t write anything particularly strange or advanced, right?

The things I drew in the notebook are all based on my past research, today's course, and reasonable inferences based on the two, right?

Perhaps because his anxious look was too obvious, the Lord of Thunder stopped flipping through the record book and glanced at him with a half-smile:

"Why are you looking so weird? Did you write something in the notebook that you shouldn't have written? - Or was it that I was lecturing on top and you were drawing for me on the bottom, and you didn't dare to let me see it?"

This really doesn’t happen!

Grete shook his head, shook his head, shook his head vigorously. Around them, the alchemists who were working stopped their work and looked sideways one by one with sad eyes:

What a great opportunity!

The Lord of Thunder personally teaches you!

I personally flip through your little notebook, read your fragmented, scattered, and unsystematic flashes of inspiration, pick out the valuable parts, discuss with you, and point you in the right direction!

There is still time to worry about what is and is not, and there is still time to worry about what I should not have written in my draft book, and what to do if the teacher sees it...

It’s really like drought and drought, and waterlogging and waterlogging! Like us, although some of our teachers are also legends, we don’t have that much patience to give guidance...

Balot's teacher wanders in different dimensions all year round. Clifford's teacher can never be found except for weekly meetings and Q&A. Next door, the teacher of Conjuration Department Haken, if you are lucky, you can contact him once a month. !

Feeling sad in their hearts, they turned their heads in unison and immersed themselves in their work. They only pricked their ears again and again, pricking them as high as they could.

Damn it, when I studied human body transformation before, why didn’t I solidify the spell to improve my hearing on my ears?

Even if the auricle can turn in one direction! If you can turn it in another direction, you can hear it more clearly! In front of a legendary mage, he wouldn't dare cast spells to improve his hearing, so he could only listen like this...

"What did you write here? Wave-particle duality? I don't remember that I used this word... but it is quite interesting and the description is very accurate..."

What is the Lord of Thunder saying?

What are you talking about?

The latest research progress?

What aspect is it about?

Is this something we – can listen to without paying?

The alchemist tried his best to prick up his ears, feeling excited, nervous, and a little excited about eavesdropping. The Lord of Thunder looked around, suddenly smiled, raised his hand to grab his little disciple, and disappeared in a flash.

The workroom was empty, leaving only his voice lingering:

"It's not that I won't let you listen, but there are some advanced contents that won't do you any good if you listen to them. Work hard and when the time is right, I will let you know bit by bit."

"ah……"

"Discovered..."

"What a tragedy..."

"It's nothing tragic. Fortunately, the Lord of Thunder is not angry..."

"Let me tell you, is this for the sake of Master Nodmark... Otherwise, the rest of us would be kicked out of the studio..."

"Is your 'bombing' a verbal command, or a direct blast with magic?"

"Stop talking...just work, work..."

Alas, there is nothing to envy. If someone has a good teacher, that's their skill. Besides, Mage Nordmark’s ability is worthy of his treatment——

Didn't he realize that there are so many of us, so many level 17, 18, and 19 magicians working under him? When he built this mage tower, he was only level 15!

It is said, it is said... that the Lord of Thunder can advance so quickly, and that his disciples can advance so quickly, is inseparable from Master Nordmark...

In recent years, many research projects in Thunder Horn were actually started by the mage Nordmark... Who said that? Don't ever say it was me who said this melon won't stay ripe...

But, just look at the papers published by Thunder Horn in the past few years and the signatures of the papers...

The alchemists murmured and murmured, but still kept their heads down in their work. In the study room on the top floor of the mage tower, Gretel was worried as he faced the teacher's question:

"Did you understand today's lesson?"

"understood……"

"What did you understand? Tell me about it! What else are you not sure about and don't know how to use it? Please tell me in detail..."

Grete cautiously began to retell the content of the day's lecture. Only a third of the way through, the Lord of Thunder frowned subconsciously:

wrong. He thought, there was something wrong with what this little guy said. It doesn’t feel like I fully understand and understand what he said, especially the part about the demigod’s virtual reality. Instead, it feels like——

Instead, it was like I had peeked at the textbook and memorized it directly, but I didn’t know what I was memorizing!

He waited patiently for a while, and the more he listened, the more surprised he became. Finally, he raised his palm and called a halt:

"Wait a minute. I remember that from beginning to end, I was talking about electrons, and that electrons have wave properties—and particle properties. How did you mention light to me? When did I say that light is a wave particle? Duality?"

Gretel:! ! !

Oops, I spilled the beans!

All along, in his concept, wave-particle duality refers to photons. After the double-slit interference experiment was completed, he suddenly remembered that electrons seemed to have wave-particle duality...

It seems that the demonstration of this effect started with electrons and later extended to photons... How did it extend to the past? It seems that it was not taught in class. They are not studying the history of the development of physics!

"Well, I think, I think, Guang may be like this..." He had no choice but to answer bravely:

"Don't the particle sect and the wave sect always have their own truths and evidence... Maybe, light is also like this, with both particle and wave attributes..."

"Maybe?"

"Perhaps we can design an experiment to prove that light also has these two properties at the same time?"

He is still reasonable. The Lord of Thunder was angry and funny for a moment. He didn't know whether he should criticize him for being whimsical, or encourage him to continue talking - maybe? Maybe?

As soon as I hit my head, it was "maybe"——

"So, how do you think this experiment should be designed?"

I do not know!

Grete looked at the teacher pitifully. From guessing that light "may" have both wave properties and particle properties to proving that light "does" have both wave properties and particle properties, there is a gap of at least one Nobel Prize——

Maybe more than one Nobel Prize. Who was the scientist who proved this in history?

Looks like Einstein!

Teacher, do you think I look like Einstein? Teacher, do you think my ability and talent are as good as one of Einstein's little fingers?

In the entire human world, there have been six to seven hundred Nobel Prize winners so far - here we only count the Nobel Prize in Physics, Chemistry, Physiology and Medicine, not the Literature Prize and the Peace Prize - there are several Einsteins. ?

That was an epoch-making figure!

Wait, how did Einstein prove the wave-particle duality of light? I don’t expect detailed formulas anymore. I can’t copy them out, and even if I could, I wouldn’t use them in calculations, but...

It seems, as if, as if, there is something called the photoelectric effect...

What the hell is that?

Gretel quickly immersed himself in "Medical Physics". Thank God it’s in the book. From Planck's energy quantization theory, to the photoelectric effect, to Einstein's photoelectric equation, the book is clearly written.

Not only is it written extremely clearly, but what is the photoelectric equation, how to derive it, why it is derived in this way, and what assumptions Einstein used are all written on it.

However, after watching it for a long time, Grete still had only one thought:

He recognizes me, I don't recognize him...

Every word in the book, every line of notes he wrote on the page, the graffiti on the corner of the page, and even all the teacher's tone, demeanor and every cadence during class, thanks to the memory that comes with time travel, Grete remembers them clearly. Chu.

But, it’s of no use... I shouldn’t be able to understand it, but I still can’t understand it...

In other words, I had read the course, memorized it, passed the exam, and answered the questions on the paper. Close the book and ask you directly:

Why did Planck calculate this Planck constant?

Why does a change in Planck's constant mean that this universe is not the previous universe?

Why can the photoelectric effect equation explain the wave-particle duality of light?

You say, you say, you say!

Gretel couldn't tell. In other words, Grete was unable to express these contents in his own words and with his own understanding. In addition to endorsements and mechanically copying those formulas, the meaning of the formulas was still a mess in his mind...

However, the teacher's urgent tracking is still very stressful. Grete struggled for a long time, and under the teacher's serious gaze, he said:

"Electrons have wave-particle duality. As for light, we guess it also has wave-particle duality. So, by emitting electrons one by one, maybe we can excite photons one by one?"

…Do you think I haven’t tried this method? The Lord of Thunder did not speak, but his eyes became scary, which obviously answered this question. Gretel scratched his head:

"Then, how about emitting light and seeing if it can excite electrons one by one? Shine very weak light on the electrode and see if it can excite electrons?"

The Lord of Thunder was silent. He stared at Gretel closely, his fingers flicking gently in the void, a slight current and light twining around his fingertips.

For a moment, Grete's vision went dark and he had already changed space. The feet were soft, as if they were stepping on the void, but strangely they did not fall directly; there were stars around them, and in the complete darkness, there was a faint light emerging——

And the Lord of Thunder stands at the end of darkness. With his hands open and clasped in front of his chest, a glimmer of light shot out from the tip of his left index finger and landed on a very thin piece of metal.

His lips pursed into a thin line, and his eyes focused on the void between the two metal pieces.

When Grete got closer, he discovered that two metal pieces were suspended in parallel, each slightly concave inward, and restrained by a force field. Maybe, maybe, should, a vacuum tube is made to allow electron flow to form between the cathode and the anode?

Therefore, as long as the dim light shining on the metal sheet can excite electrons, then the current can be measured. Of course, with the powerful mental power of the Lord of Thunder, he should also be able to directly sense electrons?

"Here, teacher, are there any electronics?"

The Lord of Thunder turned his eyes and stared at him silently and meaningfully. Gretel was silent for a moment and scratched his head:

"Well, teacher, if you can't excite electrons for a while, you might try changing the frequency of light...from infrared to ultraviolet, one by one, try separately. Is there always one that works?"

The light is dim and bright, bright and dim. From invisible and colorless infrared rays, to red, orange, yellow, green, blue and purple light, it soon returned to colorless.

Seeing this situation, Grete didn't know whether to praise "The magician is so strong, he doesn't need to fiddle with the experimental equipment, just rub it with his hands", or whether he should praise "The teacher's rainbow light magic is really well practiced, seven colors are rotated, and no additional spells are needed!" "

After the seven colors rotated once, the Lord of Thunder raised his eyebrows slightly, and it seemed that he had indeed gained something. Gretel didn't wait for him to ask, and said quickly:

"Teacher, even if the electrons are excited, there is still a lot of work to be done! - For example, we need to calculate the energy of light and the energy of the escaped electrons, and then calculate their ratio;

We need to constantly change the frequency of light to see if there is an upper limit and a lower limit. If it is lower than the lower limit, electrons will not be excited. If it is higher than the upper limit, the current will not continue to increase;

We also need to replace different metal sheets to see if different metal sheets have different upper and lower limits..."

"alright!"

The Lord of Thunder shouted softly. Gretel is really good at giving people jobs. With his few casual words, everyone in the Thunder Horn has to lend a hand, especially Philby, who studies electrical magic——

Oh, the people in Philby's hands are too busy. Do you want to go back and find other magicians who study light magic and the plasticity system?

All in all, these projects are estimated to be enough for a hundred magicians to work day and night for several years...just collecting data will keep them busy for several years...

"Okay, you can go about your business." The Lord of Thunder waved his hand calmly. Gretel's eyes dimmed and then brightened, and he had returned to the top of his mage tower.

A flash of light flashed before his eyes, and the Lord of Thunder had disappeared from where he was. He didn't know where he went...

"teacher……"

Grete stared in the direction where the teacher disappeared and said silently in his heart:

"Work harder! Derive the mass-energy equation!"
