It's been three days since the Guardian of the World demonstrated his extradimensional powers.

The Origin Light Cluster has been used, and now four-fifths of Adam's soul has the Origin characteristics, and the quality of his magic power has been further improved, and the energy content of the unit of magic power has increased several times compared to the original, and the power of various magic has also increased a lot.

He didn't pay much attention to this kind of ascension, and during the past three days, his mind was full of both ideological and material content, constantly thinking about how he could open a gap in the 'box' and integrate his subjective will into knowledge and magic.

No matter how he thought about it, he still felt that it was too unobjective and abstract, so he simply gave up the idea of finding direction in the ideas provided by His Majesty Croft, and prepared to continue his experiment.

He felt that no matter how difficult the proposition was, the result could be obtained from the formula and experimental data.

The Personal Chip Research Institute has become a large research base across the Holy Tower, nominally headed by Adam, but in reality, Adam does not have the authority to transfer and direct his mages except for big data and cloud computing-related projects.

So he still had to do his own experiments with his clones.

However, the current clones are very different, each clone has contracted a chip, joined the joint computing network, and the work efficiency is much higher than before.

Before he derived Maxwell's equations and Lorentz force equations, it was not difficult to derive classical electromagnetism except for the theory of starting from scratch, because it described the macroscopic and visible to the naked eye, but when Adam came to the fourth level and needed further theories to support his research in order to advance to the extradimensional and even make an opening in the 'box' of ideas and matter, the subsequent research became very difficult.

On Earth, the establishment of quantum electrodynamics is the result of the joint efforts of many great physicists, and it involves many magical experiments and obscure theories, while in the mage world, so far, Adam is alone, and he wants to achieve so many genius results with the power of one person, even now that he thinks about it, it is almost an impossible task.

Previously, after deriving the complete Maxwell's equations in the etheric environment, he mastered the electromagnetic field from a macroscopic level, and obtained the power of various current elemental magic, so he discovered electromagnetic waves, and to a certain extent, he can use electromagnetic waves, but in fact, it can only be used, and he can't actually analyze it fundamentally.

After thinking about it for a long time, Adam decided to start from this aspect, starting from the most basic visible light, and analyzing the nature of light in the etheric environment.

Here it is necessary to complete several classical physics experiments - light interference experiments, photoelectric effect experiments, and blackbody radiation experiments.

The first thing to be done is the blackbody radiation experiment, from which a very important constant, Planck's constant, can be derived, and only when the specific value of this constant is calculated can the next series of studies be carried out.

Adam first needed to make an absolute black body out of materials, this ideal model that only existed in theory on the earth, and it could not be complete in the mage world, but the power of magic and magical magic materials could make the effect of the black body closer to an ideal state.

After several days of searching and experimenting with materials, Adam made an object that absorbs radiant energy at any temperature and at any wavelength in a ratio infinitely close to one, thus acting as an absolute black body.

The experiment quickly got on track after Adam's radiation output tended to be correctly stable.

For the first time in this period, Adam felt exhausted, and the research he was doing now and in the future was a set of knowledge that was completely different from the previous system, which was equivalent to starting from scratch again, and he could foresee that the future would often be more difficult than before.

After seven days, hundreds of repeated experiments, and thousands of data comparisons and analyses, Adam finally measured the value of Planck's constant in an etheric environment, and replaced it with the symbol h.

The difficulty lies in assuming that the absorption and emission of electromagnetic waves are discontinuous, but carried out in parts, in which case the calculation results can be consistent with the experimental results.

Each energy is equal to hν, ν is the frequency of the radiated electromagnetic wave, and h is a constant, which is equal to 6.62606896(33)×10^(-34) J·s.

Adam did not bother to study the phenomenon shown by the blackbody radiation experiment for the time being, and after measuring this value, he stopped the experiment and switched to the light interference experiment.

This was much simpler, Adam made the experiment as fast as he could, he made a small hole in a wooden board, then covered it with a thick piece of paper, poked a small hole in the piece of paper for the light to pass through, and used a mirror to reflect the light through, and then he used a very thin piece of paper to split the light into two beams from the middle, and saw the intersecting light and shadow.

The experimental results show that two rays of light can interfere with each other like waves.

Adam then performed several other simple experiments to verify the diffraction and polarization of light, which indiscernibly illustrated the wave-like nature of light.

Having come to this conclusion, Adam ignored the changes in his soul and immediately began to prepare for the photoelectric effect.

This time the equipment took a long time to build, and it took ten days before Adam was ready to complete the materials.

He closed the laboratory and all channels through which the outside world could contact him, and devoted himself to the experiment.

Half a month later, after testing the phenomenon of electromagnetic waves of various frequencies irradiating metal materials, Adam found that the electrons inside the matter would be excited by photons to produce an electric current, that is, photoelectricity.

This phenomenon verifies the existence of photons and the correctness of Planck's constant.

When the conclusion appeared, his soul changed again, and Adam forcibly suppressed the rising power, sealing himself non-stop to begin the verification of the Compton effect.

Another month passed, the series of experiments were completed, and Adam began to summarize all the experimental data, the photoelectric effect experiment and the Compton effect, and irrefutably proved that light is particle.

At this point, the fluctuation and particle nature of the light were verified, Adam released the seal on himself, and a relatively faint aetheric light descended on him, increasing his soul power and magic a little.

More crucially, he finally gained the ability to manipulate visible light.
