No. 7 position:

That “authentic” rabbit Dandan (Toppy Sir)’s research on current in PHF:

“We have negative charges (electrons) moving so we have a current. The other way to look at it is to say we have a flow of positive charges (holes) and get the same current. (The flow of positives is in the opposite direction of the negatives.)”

Piggy’s additional comment here:
The definition of current nowadays is "the amount of charges pass through unit surface in unit time". This traditional conception of current is unilateral (charge moves relative to any reference frame)
Dandan’s conception of current is actually bilateral (Charge moves relative to charge). A bit different.
If Dandan always hugs his “holes” (reference frame established always on his “holes”), can he get "the same opposite current"? Nope.

Actually that “authentic” rabbit broke through the “standard” limitation and became an “eccentric” rabbit. He himself wasn’t AWARE of it. That’s fun.

Next, we resort to some thought experiments to analyze which conception of current could be more sufficient in science.

1. A circular dish is charged with an iron rod in the center. When the dish rotates, a guy on the ground considers that there is current and generates magnetism and the iron rod becomes a magnet; while another guy standing on the dish considers that there is no current and no magnetism generated and the iron does not become a magnet...
Is the iron rod a magnet or not?
Someone might say that although the guy on the disc would observe he was not rotating and the charges don’t move, but he would experience rotation evident by centrifugal forces he feels. So, he will consider the iron rod becomes a magnet too. Sounds reasonable too. But this explanation has deviated from the original topic of conception of current.
If we use bilateral conception of current (charge moves relative to charge) to analyze, no matter that guy standing on the ground or the disc, he would observe charges move relative to charges. So, he will consider the iron rod becomes a magnet no matter standing on the ground or the disc. This explanation works too, and doesn’t deviate from the original topic of conception of current.

2. Okay, maybe situation of acceleration is a bit complicated. Next, simplified the researching method.
If an electron moves to you in constant velocity (reference frame built on you), you will feel that magnetism occurs because you observe current; if the electron is fixed over the ground (reference frame built on the ground / electron) and you move to it in constant velocity, you will feel no magnetism occurs because you observe no current.
According to the relative movement principle, these two cases are equivalent. Why difference occurs in our sense?

Take the remaining positive charge (because charge conservation, there must be a positive charge elsewhere) into consideration and employ the bilateral conception of current (charge moves relative to charge), the answer appears.
In the former case, the electron might move relative to the remaining positive charge, while in the latter case, the electron might not move relative to the remaining positive charge. They might be different cases logically.

3. Okay, a guy and a partner research together.
Fix a plastic ball over the ground and brush it with a piece of cloth or leather, which one is appropriate (charged by friction). Put a compass beside the ball. Put the cloth or leather on a table nearby. Walk to ball and watch if the compass turns. The guy and the partner walk to the ball in the opposite side and watch the compass.
(Assume the ball, the cloth and the compass are relatively static. The guy always set the reference frame on himself, while the partner always set the reference frame on herself.)

The guy and his partner will see the compass turns in opposite directions. That’s obvious contradiction in logic.

If they take the cloth into consideration and employ the bilateral conception of current (charge moves relative to charge), they both would not observe current, then magnetism occur, then they both would not observe the compass turn. No contradtion.


4. Talk about the Stern-Gerlach experiment again.

https://physicshelpforum.com/data/attachments/2/2169-54a2a18d4408e388d6e074eff5b9a304.jpg
(This diagram is a bit inexplicit, sorry. But that’s all piggy can do with my extreme limited resource at present.)

Below is piggy’s humble opinion:
Assume the electron turns around the nucleus counterclockwise on the paper,
A. If view from the point of the nucleus, we got a single current clockwise. (Figure 1)
B. If view from the point of the electron, we got a single current counterclockwise. (Figure 2)
That will result in two different orbital magnetic moments in counter directions.
What will nature do? To be FAIR.
That’s why those atoms separated into two symmetric parts.

Because the electron can be in different energy levels of the atom, that means different orbital angular momentums and different orbital magnetic moments might occur. So, piggy estimates the spectrum will separate further step on the base of those two symmetric parts.
With the bilateral conception of current (charge moves relative to charge), piggy understand it better and simply.

Summary:
In one hand, the traditional definition of current is “the amount of charges pass through unit surface in unit time”. A question here is that where does the unit surface establish? It’s not defined. That’s to say the traditional conception of current is charge moves relative to any reference frame. It’s unilateral.
While In another hand, the rule for deciding the direction of current is “the moving direction of positive charge”. A question here is that relative to what? Ether? It’s relative to the free electrons. For example, in a section of wire in a DC circuit, the free electrons moves rightward, the cations move leftward relatively, then we got the same amount of counter current…When we say “the free electrons moves rightward”, it’s relative to the cations. When we say “the cations move leftward relatively”, it’s relative to the free electrons. Actually, it’s a conception of charge moves relative to charge. It's bilateral.
There is an obscure flaw in the traditional conception of current.
Those “authentic” guys often contradict themselves. 呵呵

Perhaps piggy has to accept the First Limitation claimed by the First Logic (the First Order) to do a security guard in the Jiangmen city. Unfortunately, piggy is old and is in bad health (due to the cruel and all around dark sanction of the First Order for so many years), piggy even is not able to secure his own old bones. That means piggy die hard logically. Bounce…
Nonetheless, today piggy, an alive - dead man of the Jiangmen city can still PRESENCE in this world and do something meaningful in science as well as meaningful in piggy’s own life too. Piggy feels very glory.
Thanks G*. Thanks a2k. Thanks America.

Piggy found that those pictures of rabbits and pigs in my threads can’t be seen in my browser anymore. What a sadness.
Actually piggy even can't access PHF at present.
Piggy suggests PHF galaxy released those lovely rabbits and pigs. Otherwise, piggy would condemn PHF mistreat little animals. Bounce…
They should pursue rational new research. Otherwise, their knowledge would be constrained by their own “standard” thought and lag behind one era. Piggy thinks.呵呵

Seems piggy exactly estimated the pig’s situation is getting worse and worse and prepared some materials a few weeks ago. Haha
Next go on with the PHA. Piggy is fair.

(The story of “Travelling to the West” 西游记 is a story of adventure. The adventure team encountered all kinds of monsters and difficulty in the journey. The pig almost became a delicious steamed pig on the dinner table of the monsters for many times…)

No. 6 position:

That “authentic” rabbit Dandan (Toppy Sir)’s research on current (one thing two aspects) in PHF:

“I suppose it might seem reasonable to suggest that the two particles would experience different changes to the electric potential, but in actuality the magnitudes of the potentials are the same so the two particles react the same.”

Piggy’s additional comment here:

Piggy’s original scenario was:

“Here construct a simplest system: a proton on the left side and an electron on the right side. Two charges move relative to each other (one thing). When the frame of reference is established on the proton, the electron is moving (one aspect). When the frame of reference is established on the electron, the proton is moving (another aspect). In respect of electromagnetism, are these two aspects different? In another word: an electron moving relative to a proton or a proton moving relative to an electron are different events logically?”
“Assume the distance between the two charges is increasing. Then, what the electron experiences is electric potential decreasing, what the proton experiences is electric potential increasing. (Or say, the electron moves in the direction of electric line of force, while the proton moves in the counter direction of electric line of force) Logically, they seem to be different events?

Logically, they are different affairs and there might be different effect in physics.

The traditional unilateral conception of current can’t demonstrate this obscure difference, while the bilateral conception of current can do it. So, the bilateral conception of current could be more sufficient in science.

Relevant material for reference:
The S – G experiment in the No. 7 position ahead. And piggy’s alternative analysis there.

I don’t know. Perhaps we all dead…thereafter, FBI goes to investigate.
Whose mission is it? The First Order?

No. 5 position:

That pig head neila9876’s research on the “analysis of the speed of probability wave” in PHF galaxy in 2020.
 https://pic.ntimg.cn/file/20150831/21698751_152045769760_2.jpg

Piggy’s additional comment here:
I don’t know how to display the full context of the “analysis of the speed of probability wave” here because I am not able to use the software to show some mathematical calculation. What I can do is to show its abstract.

The beginning of the context is:
According to Duc de Broglie’s original idea, the frequency of probability wave γ = E / h, the wavelength of probability wave λ = h / p.

The speed of probability wave of a free particle could be calculated as below:
If v is the moving speed of the particle, then, the speed of the corresponding probability wave:
u = γλ = (E / h)( h / p) = E / p =…

The conclusion of the context is:
When v → 0, Lim u = 0,
When v → c, Lim u = c,
When 0 < v < c, v > u

There are two hard problems as below:
1. What does the inconformity between “v” and “u” in case of 0 < v < c mean exactly in physics? It represents the wave state separating from the particle state? How lame it all sound. It’s too abstract and not understandable. It just means the concept of wavicle (wave – particle duality) in QM can’t establish in this situation. Why?
Seems there is a flaw here in QM.
2. And what does the conformity between “v” and “u” in case of “v → c, Lim u = c” mean exactly in physics? It should mean the concept of wavicle established in this situation. Why?

The traditional conception of probability wave lacks of a “sound base”. Piggy has given it up. (The other major reason caused piggy given up the traditional conception of probability wave is “the amplitude of probability wave function non – sense in physics”.)
For details, please see relevant materials in the thread “T vs R (2)”.

Now we have a better choice: the new conception of “electric wave”. QM should be the science to research the wave characteristics of electric interaction or say wave function is to DESCRIBE “electric wave”.
Then, QM can escape “capital punishment”. 呵呵
What the traditional conception of probability wave can do, the new conception of electric wave can do it too.
The difference is the new conception of “electric wave” has a “sound base” and explicit physical meaning and is more understandable. Moreover, it can solve the problem of “incompatibility” between Relativity and QM. The wonderful affair is it can INTERCONNECT classical electromagnetism.

The answer to the why above is as below:
1. The range of velocity of 0 < v < c is just the character of movement of spherical electromagnetic wave.
As a whole, spherical electromagnetic wave doesn’t demonstrate wave characteristic. It demonstrates particle characteristic only.
Wave is the wave characteristic of electric interaction, not the wave characteristic of the particle such as electron itself. The “wave” and the “particle” are different independent things. It’s unnecessary for the speed of “electric wave” “u” to be in conformity with the moving speed of the particle “v”.
A vivid analogy: A boat moves on the water and activates water wave. The water wave and the boat are different independent things. It’s unnecessary for the speed of water wave to be in conformity with the moving speed of the boat.
2. The Chen’s physics model for a released photon is “a section of electromagnetic wave travelling in straight line”, “a section” is from the angle of “particle” while “electromagnetic wave” is from the angle of “wave”. Of course v = u = c. Perfect conformity. Notice, at this moment, “u” changes to be the speed of electromagnetic wave rather than the speed of the “electric wave”.

(Piggy knows that pig head neila9876’s original version of “analysis of the speed of probability wave” in his thread “wavicle, an old topic” in the quantum forum in PHF galaxy in 2020 was a primary and rough one. It’s me help him renew and improve it. Haha. But the spirit of PHA is to promote scientific research and bet on those outstanding AWARENESS. If someone wants a newest version of “analysis of the speed of probability wave”, he can pm piggy. )

The research on the “analysis of the speed of probability wave” would be the break though point in this revolution of physics.
