Lin Ke was writing furiously, both hands working together, leaving afterimages on the paper, with his eyes emitting a remarkable white light.
"The speed of spherical light emitted by any light source is isotropic in every inertial reference fra and always equals c, and the laws of physics are the sa within all inertial reference fras."
"The actual mass of an object is the sum of its rest mass and the extra mass gained through motion. When an external force acts on a free particle at rest mass, the increase in kinetic energy as it undergoes displacent is..."
"If the external force is in the sa direction as the displacent, the above equation becos... According to the Lorentz transformation, the formula for mass transformation is..."
The magic power within him flowed continuously without diminishing, and in this massive consumption, so formulas were imdiately derived and simulated by him.
Mass, energy.
Mass, energy.
Mass, energy.
Right now, Lin Ke's entire mind was filled with formulas, theorems, phenona, results, proofs... all concerning mass and energy!
For an object, if you cut it in half, do the sum of the masses of these halves and the original whole's mass weigh the sa? But is this really the case?
Perhaps the change in mass is just due to asurent inaccuracies?
How about starting from the microscopic level?
An iron atom contains 26 protons, 26 electrons, and 30 neutrons.
However, the mass of the iron atom is less than the sum of the mass of a standalone iron nucleus plus 26 electrons, also less than the combined mass of 26 protons and 30 neutrons.
Why is this?
Energy is released when electrons, protons, and neutrons combine into a nucleus!
And this energy cos from the conversion of mass, so the components of the iron atom lose mass in the process of forming the iron atom.
The sun is similar too.
About three-quarters of the sun's mass is hydrogen, with most of the remainder being helium, and the temperature at its core is as high as 16 million degrees with significant pressure.
Under these extre conditions, nuclear fusion occurs between protons—two protons provided by hydrogen atoms combine to form a deuterium nucleus.
The deuterium nucleus then combines with two more protons successively, forming a helium-4 nucleus, and the mass of the helium-4 nucleus is only 99.3% of the mass of the four protons that ford it!
This ans 0.7% of the mass has been converted into energy and released.
In the process of forming each helium-4 atom, about 28 V of energy is released.
A helium-4 atom is so light it can almost be ignored, but the sun produces 596 million tons of helium-4 per second, the energy generated in the process is astonishingly huge.
So all of this reveals the conversion relationship between mass and energy!
Mass can create energy, and energy can similarly create mass.
The mass of an object is divided into rest mass and motion mass. Motion mass is related to speed: the greater the speed of the object, the greater its mass.
Thus, if we increase the speed of an object, it will contain more energy, making it possible to convert into other objects with greater rest mass.
For example, if we accelerate two electrons to a sufficiently high speed and make them collide, a new pair of particles can be produced!
One matter particle, like an electron, muon, proton, etc., and one antimatter particle, like a positron, antimuon, antiproton, etc., are thus created, and the rest mass of this new pair of particles is greater than the rest mass of the two electrons.
This is the essence of the mass-energy equation!
An equation identity lies in the arbitrary conversion between the sides of the equation.
And the mass-energy equation represents that the mass and energy on both sides of the equation can be converted into each other.
This is where its terror lies.
"Mass and energy..."
In Lin Ke's mind, various experints concerning the two were simulating, colliding.
In an instant, hundreds of thousands of experints were ongoing simultaneously, all based on the actual situation of Naseng.
From gaining weight after eating food to the microcosm of atoms and electrons.
From cutting through lines of magnetic force to the depiction and application of magic and skills.
All the motives, progression, and results of these experints were simulated in Lin Ke's mind and then written down on paper.
Originally, the paper drawers connected to all the paper mills should have extended infinitely, with the amount of paper inside decreasing at a visibly perceptible rate.
If it weren't for Naseng already being considered an industrial magical society, Lin Ke alone might have used up the amount of paper a country would consu in a past life.
Fortunately, once those paper mills discovered the paper orders from Great Wilderness University, they imdiately began production, so the paper in the drawer on Lin Ke's desk was always sufficient.
At the sa ti, all of Lin Ke's derivations and experint results were docunted on paper, the dense manuscripts stacking from one corner of the wall to another.
The entire room was almost subrged in paper!
The dark blue pen in his hand operated at full speed, with strands of feedback rging into it.
The dark blue pen experienced a whole new transformation amidst Lin Ke's furious writing.
And at a certain point in ti, soone quietly entered this room.
It was John!
The changes in the entire Magma Territory could not escape John's attention, not to ntion a major event like the lockdown of Great Wilderness University.
John naturally deduced the reason for this event.
So, regardless of how important or urgent the outside matters were, he put everything aside and returned to Great Wilderness City.
Subsequently, he ticulously organized Lin Ke's densely filled manuscripts and stored them in the Space Ring.
And he placed a cup of warm Gula Milk within Lin Ke's habitual reach.
Not uttering a word, for more than a month no actions could be seen.
John quietly stood behind Lin Ke, helping him organize things, adding milk, or placing so snacks.
Lin Ke was deeply imrsed in the ocean of derivation, his body reduced to re instinct.
If anyone else ca here, even Rica, Fulon, Ove, and the like, they'd probably unintentionally disrupt Lin Ke's state.
However, it was John who ca here.
Since childhood, Lin Ke suspected even he didn't know his habits and preferences, but John knew.
So, Lin Ke's very instincts had grown accustod to John's presence.
Thus, Lin Ke unconsciously picked up the Gula Milk and drank it, unconsciously ate a piece of sour milk cake, unconsciously handed the drafts to John.
After John's arrival, Lin Ke's derivation speed was also enhanced.
John was, after all, the [Butler]!
Skills—Assist!
Skills—Coordinate!
Only John could help Lin Ke with his abilities without waking him up.
For others, even if Knicks ca, that kind of healing magic would likely make Lin Ke aware and alert.
Thus, with John's company, Lin Ke's speed got faster, and faster, and faster...
Until two days later, John's statue-like body moved slightly.
For he noticed that Lin Ke's pen had stopped!
Lin Ke stretched deeply, then the eyes as if they were suns, looked towards John behind him:
"Huh? John? When did you get here?"
