[Infrastructure] Rose kissed Barcelona

Under the wavy light blue ceiling, Mary sat at the long wooden table, nibbled on the crispy bread wrapped with roasted tomatoes in one hand, and flipped through the physics book with the other.

Usually at this point, Mary was alone at the table—the only one in the house who was still in middle school and had to get up early to eat and go to school.

But today is unusual.Antonio woke up very early in the morning, unexpectedly catching up with her, a middle school student, for the same breakfast.

Oddly enough, he didn't seem in a rush either.

He sat across from her, neither eating nor talking, just stirring the coffee in his hand silently.That focused and pious appearance made Mary feel that he was diluting the concentrated sulfuric acid, and it would burst if he didn't stir it well.

There were people busy in the kitchen, but the two people in the dining room were silent, and it was eerily quiet for a while.

Mary ate the last piece of crisp bread in one bite, and kept her original posture until she finished reading the experiments on this page, and then reluctantly put the book aside.

She picked up a towel to wipe her fingers, and politely reminded: "Mr. Gaudi, if you don't say anything, I will go to school."

"Mary, let me ask you a question." Antonio spoke at the same time.

"Never mind. Go ahead." Mary blinked.When she said nothing.

Antonio coughed lightly, with a serious face: "What should a boy do to make you fall in love with him?"

Mary: "..." So suddenly?

Haven't really considered this issue.

She thought for a while: "Uh...maybe, send me a new element?"

Antonio was stunned: "Then... can someone really catch you?"

Mary tilted her head and spread her hands: "Isn't this just what I want?"

Antonio: "..." This is not a good sign.

"Okay. If there is no second question, I'll go to school. See you this afternoon." Mary put the book in her schoolbag and walked out.

"See you in the afternoon."

"By the way, no puppy love."

"Oh." Mary secretly rolled her eyes behind her back.

Do you think I'm you?

People who are in love are fools, even famous geniuses are no exception.

……

"Niobium?" Joey looked at the small crystal ball in his hand in surprise.

Although it is a crystal ball, the glass seems to be a bit too thin and looks very fragile.

Inside the palm-sized transparent glass cover, a bundle of colorful niobium wires extends from the base, like a colorful double-petal rose.

It can be roughly recognized that each niobium wire itself winds a coil with a clover-like pattern, and the coils with gradient colors are fixed at the same central point.

"Yes. It's made of niobium silk—a gift to celebrate the completion of Rose's Milk Tea Shop." Antonio turned his head lightly, and leaned against the bright light yellow window lattice.

They stood by the window of the small attic facing the street on the second floor of the newly completed Rose House milk tea shop.

Joy laughed: "Why use niobium?"

She is actually very familiar with this metal.

Not long ago, when the city council put forward a grand vision for the site needed to bid for the World Expo, some rigorous engineers quickly poured cold water on it—such a huge structure, human beings simply cannot do it.

At that time, the yawning Joey interjected inexplicably: "Reinforced concrete, why can't it be done?"

"Reinforced concrete?" Everyone looked at her in surprise, and she was so frightened that she suppressed the remaining half of her yawn.

Fortunately, she soon discovered that this thing had already been invented.

In fact, even the patent already exists - but, when a French gardener exhibited this patent at the Paris World Expo in 1867, its use was only for flowerpots.No one thought of using it in architecture.

So, Joy boldly and confidently suggested: "Use it to build a house!"

"By the way, I had a dream last night, and an angel told me that adding niobium to steel can greatly increase its strength."

Thus began a revolution in building materials.

In fact, because of the good ductility of niobium, many people also tried niobium when trying filament materials in the whole city.However, its melting point is lower than that of tungsten wire, so after the determination of tungsten wire, no one cares about niobium.

The discovery of new uses makes the mine owners of niobite and pyrochlore crazy happy.Of course, architects and structural engineers are also madly happy.

The dream of human beings is to keep approaching the sky.Let the building grow taller!

Praise the great reinforced concrete.

Praise the RC lady who bought the patent from the French!

Back to reality.Why Niobium?

"Guess." Antonio raised an eyebrow.

He stretched out a hand, curled his slender fingers, and tapped a marigold on the tile, "Do you like it? This small attic."

Joey also turned around like him, leaned against the window, and looked around.

Bright marigolds bloom one after another on the mosaic tiles with green vines, while thick light red bricks are stretched along the wall, and a string of cherry branches full of cherries is painted in deep rose red.

The ceiling is the purest and boldest blue-gold color, as if stealing a clear midsummer sky.A field of birds, vines, and flowers hovered over the tiles of the fireplace.

Bright sunlight flooded the entire small attic through the bright windows, and in a trance, all the lush and prosperous animals and plants in the entire space came to life. Joey almost felt that the tip of his nose smelled the fresh floral fragrance of calendula, which was as light as green grass.

So vigorous, so luxuriant, so full of vitality, it seems that a big garden has been planted in a small attic.Who wouldn't love it?

Joey tilted his head and blinked narrowly: "What is this small attic used for? You see, the staff of the milk tea shop are only on the first floor. They are busy with work, and it is impossible to run up and down. It is beautiful here, But no one came."

Antonio turned his head and explained very seriously: "This is designed for you. It was originally just a storefront along the street, but there is still some space above the storefront, which can be used as a secret small attic-a small attic that belongs only to you .”

“I calculated the temperature and air movement in the space. In summer, the breeze will blow from one side of the window sill to the other, taking extra heat. And I also made a buffer compartment above this attic for insulation. , even if the sun burns the red-brick roof, it will be cool and breezy.”

Joey leaned comfortably by the window, and couldn't help but look at Antonio—he would only say so much in one breath when introducing his own works.

Antonio didn't realize it, and pointed to the wall facing the window: "You can put a swing chair made of agate rattan here. Whether it's winter or summer, you can sit here with your purple tooth crow in your arms, basking in the sun while drinking. milk tea."

"In summer, the water droplets on the glass are dripping down, and you are sitting in the house full of marigolds, but it is very cool."

"In winter, Ziyawu will curl up in your arms obediently, the rattan chair is covered with plush felt, and the warm milk tea is placed next to the crackling fireplace, with your favorite taro balls in it. "

Ah, that sounds so heartwarming.

Joey thought for a while, and said seriously: "Then if a fire broke out on the first floor, wouldn't it be impossible for me to escape if I'm trapped here."

Antonio seemed to be choking suddenly.

Joey: "I'm serious. As an architect, shouldn't the escape route be the first consideration?"

Antonio: "...it's only two meters above the ground."

Joey stretched out his hand and poked his chest in dissatisfaction: "Then you mean, let me jump down with Ziyawu in my arms? Will you catch me?"

Antonio grabbed her dishonest hand: "...you can put the cat down first, and then jump down by yourself."

In fact, it's not like I didn't take it.

The memory unconsciously went back to the softness in her arms with a faint girly fragrance, and the tips of her ears suddenly started to feel hot.

Joey smiled smugly, and his heart was aroused.

She quickly curled her fingers and scratched Antonio's palm.

He was shocked and shook her hand away.

Joey laughed so hard that he bent down, and suddenly saw something: "Hey, there is a rose here."

On the wall next to her, there is a relief of a rose.Nowhere else, like a totem.

There are still some gaps around the bottom tile, which seems to be loose.

She couldn't help picking it with her hands.Did not pick.

Antonio pulled her aside: "Don't pick. I'm not in charge of vandalism."

"Tch, cheapskate." Joey grimaced at him.

Antonio looked at the big clock across the street, "Why don't you go home first. I have to go to Park Güell. I made an appointment to go to the planning sketch with the count today."

"Oh, okay. Let's go." Joy remembered that she also had a lot of things to do.

It's really easy to relax in this cozy little space, and it makes people want to keep doing nothing.It's a pity that the dead line is ruthless.

When the carriage passed through La Rambla, Joey secretly pulled up the curtain and looked at Rose's house from behind the bustling crowd.

This is the annoyance of Antonio after he became famous—they couldn’t stand in front of the house to admire it openly, because there were an endless stream of tourists who came to visit it every day, and now Rose’s house had to arrange special personnel to maintain order in front of the door.

The wind blew the corner of her hat brim, and the transparent ribbon brushed over the back of her hand, and yesterday's "Barcelona Evening News" was flipped in her hand.

"Never before has a building perfectly combined such a simple structure with such an ornate decoration - the overall outline of the Rose House milk tea shop is reminiscent of the Alhambra Palace in Granada, with an archway under the flat roof line."

"This description seems ordinary - but you can never imagine what kind of masterpiece can be collided with such a simple combination."

"Bright red bricks set a bright, rustic tone, with marigold green tiles interspersed with white tiles in a checkerboard mosaic pattern. Bright, bold color contrasts make this house look It is like a fairy tale reflected in reality, a mysterious and gorgeous island of 'Arabian Nights' in the sea of ​​Greek and Roman mythology."

"Unlike the roofs of the Fernandez House and the Earl's House, we can see the obvious oriental features from this building, which makes it stand out on the entire classical and neoclassical Rambla Street-yes, this For a time, even the famous Earl's House was eclipsed by its charm."

"We have even more interesting discoveries. If the real designer of the House of Fernandez hadn't surfaced, we wouldn't have known it. In fact, before it, Antonio Gaudí, who was still a student, had already participated in the design of the roof of the House of Counts." .”

"As we all know, the most admirable part of that building is the roof, but the main designer of the whole house, Jose Abbas, never mentioned it when he accepted various awards. .This has to make us have some personality questions about an architect who has always been known for being well-bred..."

"Ah, the rose thread!" Joey blurted out.

When she was sitting in the carriage, she turned the crystal ball that Antonio gave her upside down, and finally found a line of small words engraved on the side of the wooden base——

r=sin(1/3θ).

This is a polar coordinate system.She probably had the impression that the formed pattern seemed to be called rose line.If you take a closer look, it seems that each niobium wire is wound into a three-leaf rose wire, and then combined together.

It seems that this is a three-dimensional rose composed of r=sin(1/3θ) functions on many planes.

Let's just say, she didn't find out the relationship between this crystal ball and Rose's milk tea shop before.

Looking at the "rose" made of colorful coils, Joey couldn't help but raise the corners of his lips.

It's a bit too abstract, but it's cute.

This is a cute and silly rose.

Turn it over again, and there is a line of small characters at the bottom of the base.Joey held up the crystal ball and looked closely to make it out.

Nbmía.

My niobium.

Return his niobium.Obviously she was the first to discover the role of niobium in architecture.

Moreover, the full name of niobium, niobio, is clearly a masculine word, and even the yin and yang are wrongly spelled, tsk.

It is indeed a gift from a straight man of engineering.Joey knocked on the shell of the crystal ball with disgust, and carefully put it into his arms.

When she was walking home through the back door that Antonio repaired urgently, she met Xiu En who was rushing out with a dignified expression, and almost bumped into her.

Joey slammed on the brakes and called Xiu En: "What's wrong?"

Only then did Xiu En realize that he almost bumped into her, and quickly apologized: "I'm sorry, Miss. I want to..."

"Sister, Xiu En is in a hurry to deliver the letter for me. Let me tell you." The young man's crisp voice came from the stairs with a hint of coquettishness, interrupting Xiu En's words.

On the winding and curly stairs, the frail young man was shrouded in the shadow of the dragon's spine handrail, looking down in this direction.

It was as if no light could fall on him.

The author has something to say: Joey: Thank you.Yes, I am very Nb.

Niobium (Nb) Niobium, the element is a shiny gray metal, but the oxide is rich in color and has good biophilicity. Like titanium, it is an ideal metal for making colored metal jewelry.Traditional use is in steel alloys to improve strength.

mía means "my", but the usage is postposition, MyNb=Nbmía.

Western nouns are divided into masculine and feminine, and adjectives that modify nouns will also use the ending -o or -a to distinguish between masculine and feminine.The Spanish name of niobium, niobio, is a masculine noun, but mía is used here instead of mío, so Joey dislikes that Antonio has a grammatical error.

Pseudo-Crystal Ball: Both the sender and the receiver are stupid, not my fault.
