Chapter 1715 Gretel: Work harder, teacher, become Einstein! (21 rewards plus [-])
"How did you understand today's lecture?"
Gretel was gesticulating with the magicians for a while, making many requests, checking their plans, and supervising their progress, and then lying on the table to write and draw, draw and write, and record every fragment of his inspiration .
Suddenly, a tepid question sounded behind him, causing him to jump up on the spot, almost dropping the pen in his hand:
"Old... teacher!"
"Huh? What are you writing? - Show me." The Thunder Lord stretched out his hand as a matter of course.Gretel was respectful, holding the notebook with both hands, standing sideways and staring at the teacher's face:
I didn't write anything, did I?
Didn't write anything particularly strange, or particularly advanced?
What I scribbled on the notebook are all based on my past research, today's class, and reasonable inferences based on the two, right?
Perhaps it was because his anxious expression was too obvious, the Lord of Thunder stopped flipping his fingers in the record book, and glanced at him with a half-smile:
"What are you doing with this weird look? Did you write something that shouldn't be written in the notebook? ——I was lecturing on it, and you drew pictures for me on the bottom, and you dare not let me see it?"
This really doesn't exist!
Gretel shook his head, shook his head, shook his head hard.Front, back, left, and right, the working alchemists stopped their work, and looked sideways one by one, with mournful eyes:
What a great opportunity this is!
The Lord of Thunder himself taught me!
Flipping through your little book by myself, reading your fragmented, scattered, and unsystematic flashes of inspiration, picking out valuable parts from it, discussing with you, and pointing out the direction for you!
There is still time to worry about what is there, and to worry about what should not be written in the draft book, what to do if the teacher sees it...
It's really drought to death, waterlogging to death!Like us, although there are a few teachers who are also legendary, they don't have that much patience to give advice...
Balliot's teacher wanders in different spaces all year round. Clifford's teacher can never find anyone except for weekly meetings and Q & A. The teacher of Harken, the conjuration department next door, if you are lucky, you can contact him once a month. !
Complaining in their hearts, they turned their heads in unison, immersed in their work, and only pricked up their ears again and again, trying to prick up as high as possible.
Damn it, before researching human body transformation, why didn't the magic of improving hearing be solidified on the ears!
Even if the pinna can turn in one direction!If you can turn around, you can hear more clearly!Legendary mages dare not cast spells to improve their hearing in person, so they can only listen like this...
"What are you writing about here? Wave-particle duality? I don't remember ever using that word... but it's interesting, very accurate description..."
What is the Lord of Thunder talking about?
What are you talking about?
Is the latest research progress?
What aspect is it about?
Is this what we -- can we listen to without paying?
The alchemist frantically pricked up his ears, excited and nervous at the same time, with a sense of excitement of eavesdropping.The Lord of Thunder looked around, suddenly smiled, raised his hand to grab his little disciple, and disappeared in place with a flicker.
The workshop was empty, leaving only his voice lingering in place:
"It's not that you are not allowed to listen, but some advanced content is not good for you. Work hard, and when the time is right, I will let you know bit by bit."
"what……"
"It was discovered..."
"Tragedy..."
"It's nothing tragic. Fortunately, Your Excellency the Lord of Thunder is not angry..."
"If you want me to say, is this for the face of Master Nordmark... Otherwise, all of us will be kicked out of the studio directly..."
"You 'bang out', is it a verbal order, or a direct spell?"
"Stop talking... work, work..."
Alas, there is nothing to envy.It is their ability to have good teachers.Besides, Master Nordmark's ability is also worthy of his treatment——
Didn't you see so many of us, so many magicians of level 17, 18, and 19, working under his hands?When he built this mage tower, he was only level 15!
It's said, it's said...the Lord of Thunder can advance so quickly, and his disciples can advance so quickly, it's inseparable from Master Nordmark...
In recent years, many research projects in the Horn of Thunder were actually initiated by Master Nordmark... Who said that?Don't say that I said it, this melon is not guaranteed to be ripe...
But, you can find out by looking through the papers published by the Horn of Thunder in the past few years, and the signatures of the papers...
The alchemists muttered and muttered, but they still kept their heads down on their work.And in the study on the top floor of the mage tower, Gretel was worried, facing the teacher's question:
"Did you understand today's lesson?"
"understood……"
"What do you understand? Tell me! If there are any places you are not sure about and how to use them, please tell me in detail..."
Carefully, Gretel began to retell the content of the lecture that day.Only a third of the time, the Lord of Thunder frowned subconsciously:
wrong.He thought, there is something wrong with what this little guy said.It doesn't feel like he has fully understood and thoroughly understood what he said, especially not like he has comprehended the half-god part, but rather——
On the contrary, it was as if he had peeked at the textbook and memorized it directly, but he didn't know what he was memorizing!
He waited patiently for a while, and the more he listened, the more surprised he became.Finally, he raised his palm and stopped directly:
"Wait a minute. I remember I was talking about electrons and electrons have wave properties - and particle properties. How did you get me into light? When did I say wave particles of light? Duality?"
Gretel: ! ! !
Oops, I slipped my mouth!
All along, in his concept, wave-particle duality refers to photons.After the double-slit interference experiment was done, he suddenly remembered that it seems that electrons also have wave-particle duality...
It seems that the demonstration of this effect started with electrons, and then extended to photons... In the end, how did it extend to the past? It seems that they didn't talk about it in class, and they didn't study the history of physics development!
"Well, I think, I think, light may be like this..." He had no choice but to answer bravely:
"The particle faction and the wave faction have always had their own reasons, and each has its own evidence...Maybe, light is also like this, with both particle properties and wave properties..."
"Maybe?"
"Maybe, we can design an experiment to prove that light also has these two properties at the same time?"
He also made sense.The Lord of Thunder was angry and funny for a while, he didn't know whether to criticize him for his whimsy, or encourage him to continue talking—maybe?Maybe?
A pat on the head is a "maybe"——
"So what do you think, how should this experiment be designed?"
I do not know!
Gretel looked at the teacher pitifully.Guessing that light "may" have wave and particle properties at the same time, to prove that light "is" has wave and particle properties at the same time, there is at least one Nobel Prize so far away——
Maybe more than one Nobel Prize.In history, who was the scientist who proved this point?
It's like Einstein!
Teacher, do you think I look like Einstein?Teacher, do you think my ability and talent can catch up with Einstein's little finger?
In the entire human world, there have been six to seven hundred Nobel Prize winners—only the Nobel Prizes in Physics, Chemistry, Physiology and Medicine are counted here, and the Literature Prize and Peace Prize are not considered—there are a few Einsteins ?
That is an epoch-making figure!
Wait, how did Einstein prove the wave-particle duality of light?I don't count on the detailed formula, and I can't copy it out, and I won't use it for calculation if I copy it out, but...
It seems, as if, as if, there is something called the photoelectric effect...
What is that?
Gretel quickly sank his mind into Medical Physics.Thank goodness 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 very clearly, but also, 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, Gretel still only had one thought:
He knows me, I don't know him...
Every word in the book, every line of notes I wrote on the page, the graffiti on the corner of the page, and even all the tone of voice and every cadence of the teacher in class, thanks to the gift of memory that comes with time travel, Gretel can remember clearly Chu.
But, it's useless... I don't understand it, I still don't understand it...
In other words, at that time, 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 the change of Planck's constant mean that this universe is not the one before?
Why can the photoelectric effect equation explain the wave-particle duality of light?
Say it, say it, say it!
Gretel couldn't speak.In other words, Gretel has no way to use his own words, his own understanding, to express these contents.In addition to endorsing, copying those formulas mechanically, the meaning of the formulas is still a mess in his mind...
However, the teacher's tight marking is still very stressful.Gretel struggled for a long time, and under the teacher's substantive gaze, he said:
"Electrons have wave-particle duality, and light, we guess, also has wave-particle duality. ——So, emitting electrons one by one may excite photons one by one?"
... Do you think I haven't tried this method?The Lord of Thunder didn't speak, but with his frightening eyes, he obviously answered this question.Gretel scratched his head:
"Then, just emit light, and see if it will excite electrons one by one? Very weak, very weak light, shine on the electrode, and see if it can excite electrons?"
The Thunder Lord was silent.He stared closely at Gretel, flicking his fingers lightly in the void, slight electric current and light entwined around his fingertips.
In a moment, Gretel's eyes went dark, and he had already changed space.The feet are soft, as if stepping on the void, but it is strange that they did not fall directly; there are dots around, in the complete darkness, there is a faint light emerging——
And the Lord of Thunder stands at the end of the darkness.With both hands open, Xu Xu put them together in front of his chest, a ray of light shot out from the tip of his left index finger and landed on an extremely thin piece of metal.
His lips were pursed into a thin line, and his eyes were focused, staring at the void between the two pieces of metal.
Gretel got closer, only to find that two metal pieces were suspended in parallel, each slightly recessed inward, and restrained by a force field in the middle.Possibly, perhaps, should, be a vacuum tube made so that electron flow can be formed between the cathode and the anode?
Therefore, as long as the shimmering light 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 perceive electrons?
"Here, teacher, is there an electron?"
The Lord of Thunder turned his gaze around, staring at him silently and meaningfully.Gretel was silent for a while, scratching his head:
"Uh, teacher, if you can't excite electrons for a while, maybe you can try to change the frequency of light... From infrared to ultraviolet, try one by one, one by one, there is always one that works?"
The light is dim and bright, and bright and dim.From the invisible and colorless infrared rays to the red, orange, yellow, green, blue, blue and purple rays, they quickly return to colorless.
Seeing this situation, Gretel didn't know whether to praise "the magician is strong, you don't need to toss the experimental device, just rub it with your hands", or should praise "The teacher's rainbow magic is really well practiced, seven colors are rotated, and there is no need to cast extra spells! "
The seven-color wheel rotated once, and the Lord of Thunder raised his eyebrows slightly, as if he had indeed gained something.Gretel didn't wait for him to ask, and hurriedly said:
"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, and if it is higher than the upper limit, the current will not continue to increase;
We also need to replace different metal pieces to see if different metal pieces have different upper and lower limits..."
"All right!"
The Lord of Thunder stopped softly.Gretel is really good at giving people jobs. With his light words, all the people in the Horn of Thunder will be involved, especially Philby, who studies electric magic—
Oh, the people in Philby's hands are too busy, so I want to go back and find someone who studies light magic and other magicians from the evocation department?
In short, these projects are estimated to be enough for a hundred magicians to work day and night for several years... just collecting data, they have been busy for several years...
"Okay, you can go about your business." The Lord of Thunder calmly waved his hand.Gretel's eyes dimmed and then brightened, and he had already returned to the top floor of his mage tower.
With a flash of light in front of his eyes, the Lord of Thunder has disappeared in place, and he doesn't know where he went...
"teacher……"
Gretel stared at the direction where the teacher disappeared, and said silently in his heart:
"Come on! Deduce the mass-energy equation!"
