The next afternoon.
Although the weather wasn't cooperative.
The light flurries from last night had turned into a heavy snowfall of large snowflakes.
Whoosh—!
But for Aiven, this was no big deal. With a gentle wave of his hand, as if it were an eraser, he wiped away the leaden clouds that covered half of the Duchy.
Besides Anita and Liweina.
He also led a gathering of Wizards, including those from the "Life Tree School," "chanical Immortality School," and witches, as well as students and professors from the Galliot National University's engineering departnt, to a small hill on Long Island.
However, it wasn't until around dusk, the scheduled test ti.
A group of [Electrical Engineers] who had graduated from the Galliot National University engineering departnt finally managed, with sweat on their brows, to complete the final adjustnts to the signal transmission equipnt located in the Far Sails Territory, sending a signal that they were ready.
Aiven observed the entire process without intervening.
In order to continue replicating and growing the "electrical era," sacrificing a little ti for practice was sothing he could tolerate.
"Wireless radio technology" is a technique for transmitting signals via radio waves. The principle lies in the fact that changes in the current intensity in a conductor produce radio waves.
Utilizing this phenonon, modulation techniques can load information onto radio waves.
When radio waves travel through space to reach the receiving end, the electromagnetic field changes induced by the waves generate a current in the conductor. Demodulation techniques can then extract the information from these current changes, achieving the purpose of information transmission.
This is an extrely practical and important branch of electrical science. Coming from the information age, Aiven was acutely aware of the power hidden behind it!
Thud!
Aiven then took out a suitcase-sized, exquisitely crafted wooden box, seemingly made of brass and walnut, and placed it on the ground—a larger version of... a radio receiver.
Radio wavelengths can be categorized into longwave, dium wave, shortwave, ultrashortwave, and microwave.
Aiven used the amplitude-modulated shortwave broadcast mode.
Because of the "ionosphere" in the planet's atmosphere.
It can act like a mirror, reflecting radio waves sent at the speed of light back to the Earth's surface instead of shooting straight into space, allowing extrely distant radio stations to communicate with each other.
The "shortwave" band can be relatively steadily reflected by the ionosphere in the atmosphere.
Moreover, shortwave has strong penetration and is less prone to interference. The signal, once reflected by the ionosphere, can travel hundreds or even thousands of kiloters.
Thus, shortwave broadcasting is suited for long-range broadcasts and can even be used for international broadcasts, possessing imnse strategic value.
Even in Aiven's ti, engineers generally considered it the most efficient way to transmit information globally on a large scale—safe, cheap, and fast.
However, shortwave broadcasting mainly uses "skywave" propagation, and due to atmospheric conditions, its transmission distance is farther at night than during the day.
Since this was the first test, of course, they had to create the most convenient conditions.
Opening the radio receiver's dial, only low static was heard inside.
Aiven glanced at the ti and whispered softly through the [Mind Network]:
"Hesi, start the test."
At the sa ti.
On the top floor of Orange Leaf Castle, ho of the Aimoer family in the Southern Far Sails Territory, next to a towering signal transmission tower and a specially made receiving device, stood an expensive-looking black piano.
Nymph and Olivia, mother and daughter, adorned in matching off-shoulder evening gowns resembling the starry night sky, exposing their slender necks and delicate arms, sat side by side next to the piano.
Exchanging a glance, they simultaneously raised their delicate hands and lightly touched the ivory keys.
Thud—!
In Aiven's eyes, from where he was on Long Island, a radio wave sliced through the air, and a captivating piano lody soon echoed from the radio receiver.
Dididongong...
It felt like a stream of moonlight, cool and clear as water, flowing silently through the forest.
It was Achille Claude's third piece from the "Begamo Suite" — "Moonlight."
Indeed, the first note ant that the first test of radio broadcasting in human history had already succeeded.
Yet the Wizards, students, and technical staff present seed to have forgotten their original purpose, including his sister and Liweina, who all slightly closed their eyes, lost in the exquisite lody.
A scene of utter silence and moonlit beauty unfolded slowly in everyone's mind. The music painted a picture, and the picture held music, with the lody capturing the flow of ti and the image reflecting still beauty.
Before their marriage, Nymph and Olivia were born into Great Noble families, with impeccable artistic qualities that significantly elevated the artistic stature of the Galliot Clan.
If they had one, that is.
At this mont.
Despite a distance of thousands of kiloters between them, listeners seed to be sitting right by the piano, holding their breath to listen intently, loath to interrupt their performance.
The experience was so imrsive that people forgot to clap entirely.
This might be the allure of art compounded with the radio, a fusion producing a fundantal change.
Even Aiven, who was rely revisiting it, found himself sowhat entranced.
Though many witchcraft tools are more wondrous than a radio, this device can be endlessly replicated using basic materials like brass, steel, and wood.
The most formidable aspect of the radio isn't the device itself, but the scale effect it heralds.
The image of all the village's inhabitants, old and young, carrying stools and surrounding a little box on the threshing ground seed to materialize once again before Aiven's eyes.
They then eagerly absorbed the imparted values, determined to beco devoted supporters of [Royal Authority].
Compared to it, the inherently flawed theater, newspapers, concert halls, traveling poets... aren't even worthy of handling its shoes.
In addition, with technological advancents already preemptively resolved.
If shortwave were replaced by microwave, and the "seagulls" of the [Mind Network] were employed as relay stations, signal strength could be rapidly enhanced, switching to a high-quality long-distance military signal.
The piece ended, and the lovely sound lingered, still resonating softly in the night air.
Clap! Clap! Clap!...
Coming to their senses, a tidal wave of applause enveloped the small hill and the Nymph and Olivia who appeared, hand in hand, stepping out from the air accompanied by butterflies made of light.
Liweina was the most excited.
A series of subversive activities in the Lowland Republic has already sufficiently demonstrated:
"dia" as a dium for information dissemination and a channel for exerting influence, plays a critical role in shaping national soft power and international authority, where doing well can never compare to speaking well.
"Discourse power" is truth, knowledge, and authority!
The impact of this new dia's birth is as powerful as several "Gods of Music and Opera" combined!
At this mont.
Whoosh! Whoosh! Whoosh! Whoosh!
Four streams of light suddenly sliced through the sky.
Angie's voice then rang out in Aiven's mind:
"Teacher, I think you'd better co and see this!"
