Chapter 1715 Gretel: Teacher, work harder and become Einstein! (Ten thousand rewards plus 21 updates)
"How did you understand today's lecture?"
Gretel was gesticulating with the magicians for a while, frothing at the mouth, making many requests, checking their plans, supervising their progress, and then 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 respectfully held the record book in both hands, stood sideways and stared 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 shouldn't be 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 exist!
Gretel shook his head, shook his head, and shook his head vigorously. Back and forth, 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 flipped through your little notebook, read your fragmentary, scattered, and unsystematic flashes of inspiration, picked out the valuable parts, discussed with you, and pointed out the direction for you!
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 a drought that leads to drought, and a waterlogging that leads to death! Like us, although there are several teachers who are also legends, they don’t have so much patience to give guidance...
Balot's teacher wanders in a different space all year round. Clifford's teacher can never be found except for weekly meetings and Q&A. Next door, Haken, the teacher of the Conjuration Department, can be contacted once a month if he is lucky.
!
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 hearing on my ears?
Even if the pinna of the ear can be turned in one direction! If it can be turned in one direction, you can hear more clearly! The legendary mage would not dare to cast spells to improve hearing in person, 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's 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 what we – can listen to without paying?
The alchemist pricked up his ears desperately, 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 with a flash.
In situ.
The workshop 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, all 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 is their ability. Besides, Master Nordmark’s ability is worthy of his treatment——
Didn’t you see 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 Nodmark...
In recent years, many research projects in the Thunder Horn were actually started by the mage Nordmark... Who said it? Don't say it was me. This thing is not guaranteed to be cooked...
But, just look at the papers published by Thunder Horn in the past few years and find out the signatures of the papers...
The alchemists were muttering and muttering, but still immersed themselves in their work. In the study on the top floor of the mage tower, Gretel was worried, facing the teacher's inquiry:
"Did you understand today's lesson?"
"understood……"
"What did you understand? Tell me about it! There are also some things that you are not sure about and don't know how to use them. 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:
No. He thought, there was something wrong with what this little guy said. It didn't feel like he completely understood and understood what he said, especially not like he had some understanding of the virtual part of the demigod, but rather 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 the properties of waves - and also have the properties of particles. 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 done, he suddenly remembered that it seemed that electrons also have wave-particle duality...
It seems that the demonstration of this effect started with electrons, and then extended to photons... How did it extend to the past? It seems that it was not taught in class, and they did not study 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 was 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 "actually" has both wave properties and particle properties, there was a gap of at least one Nobel Prize.
——
Perhaps there is more than one Nobel Prize. Who is 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 are six to seven hundred Nobel Prize winners so far - only counting the Nobel Prize in Physics, Chemistry, Physiology and Medicine, not considering 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 the detailed formula. I can’t copy it out, and even if I copy it, I won’t use it for calculations. But
…
It seems, as if, as if, there is something called the photoelectric effect...
What the hell is that?
Grete quickly immersed himself in "Medical Physics". Thank God, it was written in the book. From Planck's energy quantization theory, to the photoelectric effect, to Einstein's photoelectric equation, the book clearly stated
in vain.
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, Gretel remembers them clearly.
Chu.
However, it’s of no use… I should not understand it, but I still don’t understand it…
In other words, I have read the course, memorized it, passed the exam, and answered the questions on the paper. I closed the book and asked 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 one?
Why can the photoelectric effect equation explain the wave-particle duality of light?
You say, you say, you say!
Grete couldn't tell. In other words, Grete couldn't express these contents in his own words and with his own understanding. Apart from memorizing and copying those formulas mechanically, the meaning of the formulas was still a mess in his mind...
However, the teacher's pressing gaze was still very stressful. Grete struggled for a long time, and under the teacher's serious gaze, he said:
"Electrons have wave-particle duality, and light, we guess, 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 before? The Lord of Thunder did not speak, but his scary eyes clearly 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, slight current and light twining around his fingertips.
For a moment, Grete's vision went dark, and he had changed space. His feet were soft, as if he were stepping on the void, but strangely he did not fall directly. There were stars around him, and in the complete darkness, there was a faint light emerging——
The Lord of Thunder stood at the end of the darkness. His hands were open and clasped in front of his chest. A glimmer of light shot out from the tip of the index finger of his left hand and landed on a very thin piece of metal.
His lips pursed into a thin line, his eyes focused, staring at 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, it should be a vacuum tube, so that there is a gap between the cathode and the anode.
Form a flow of electrons?
Therefore, as long as the dim light shining on the metal sheet can excite electrons, then the current can be measured. Of course, the Lord of Thunder's powerful mental power 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:
"Uh, teacher, if you can't excite electrons for a while, maybe you can try changing the frequency of light...from infrared to ultraviolet, try them one by one. 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, blue and purple light, it soon returns to colorless.
Seeing this situation, Gretel 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 required!"
"
After the seven colors rotated once, the Lord of Thunder raised his eyebrows slightly, and it seemed that he had indeed gained something. Gretel did not wait for him to ask, and said quickly:
"Teacher, even if 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 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 stopped softly. Gretel is really good at assigning tasks to others. With his light words, everyone in the Thunder Horn has to join hands, especially Philby, who studies electric 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, and he didn't know where he went...
"teacher……"
Gretel stared at the direction where the teacher disappeared and said silently in his heart:
