"Listen to my voice, where will you go?"

"The devil lies in the abyss, or hides in heaven?"

……

In the dream, an endless voice called for Xiao Qi.

"Wow!"

A crisp birdsong woke him from his nightmare, and the uneasiness hidden in his eyes was dissipated.

Xiao Qi panicked, it was enough for him to save Audrey, and now he didn't think about anything else.

As he spoke, he looked up, "After all, I'm still that weak. ”

After the previous world and the grandmother were also separated, Xiao Qi also secretly investigated some things, and probably learned the way to save Audrey, but the matter about the grandmother is not very clear. I wanted to continue the investigation, but unfortunately my life was short, and I soon died in a hurry.

After that, he went to his friend and boss in a rage and came to the world again.

As long as you push the physics of this world, you have a chance to reclaim Audrey's soul again!

"But ......, this world, is it really possible?" Xiao Qi showed a contemptuous expression, "Decimal, I really don't know what the people here think, they actually use the decimal system, isn't it too troublesome?" It's a shame that this place can have a key. ”

With that, he walked out of his current shelter, a tree.

Xiao Qi's gaze locked on a young clerk who was walking silently.

What is extremely incompatible with this little clerk's clothes is his temperament as if no one is around. He kept his head down—unless he was attracted to the stone bricks that had been in obscurity for decades—or he was certainly like the obscure stone bricks

I'm thinking about something. If you can see his eyes, the person who looks at him will find that the other person is not looking at himself at all, but at the universe in his head.

"It should be this person," Xiao Qi confirmed, "Albert Einstein." ”

"So," Hei jumped off the tree, "it seems that our key man, Mr., is also in trouble." How can I remind him? As he walked, Xiao Hei thought.

The crisp chirping of the birds is always accompanied by sparkling dewdrops, which gather together little by little as the leaves shake, and then slowly slide down, leaving the leaves to wave slowly in place.

A drop of dew hit a leaf on the ground, and then the claws of the little fleshy flesh stepped on it, and through the leaves, stepped on a round pit in the soft soil. On the other side, there is a shallow cat's paw-shaped pit.

Xiao Qi, who was soiled because of his paws, quickly retracted it, and as if he suddenly thought of something, he began to ponder.

"As long as it prompts this, it should be fine......"

Thinking of this, Xiao Qi stretched his waist, "So, what are you going to eat today?" With that, he turned his gaze to the new restaurant that had opened on the street.

……

When night falls, the melodious sound of the violin floats among the stars, telling, asking.

Xiao Qi jumped on the roof, looked around, and began his own plan.

Seeing the cement that had just been refilled at the door of the restaurant on the corner, a black cat showed a few bright teeth in the moonlight.

The next morning, Xiao Qi calculated the time for Albert to come out of the house, jumped off the roof, and found a random leaf to stick to his feet.

As soon as Albert came out, he left two clear rows of footprints on the cement.

The footsteps approached, and the sound gradually increased, with a slight hint of haste.

Xiao Qi raised his head proudly, with a "thank me" expression.

Then, Xiao Qi watched Albert pass by him, without even looking at him.

Looking at Albert's distant back, Xiao Qi was alone in the wind.

"You cat!" Suddenly, a loud shout came from behind Xiao Qi, who was the owner of this restaurant.

You must know that Xiao Qi is eating and drinking here, and he is obviously very familiar with the boss, but the boss still grits his teeth every time he sees him, and he can't wait to develop a dish by himself.

Xiao Qi skillfully dodged the swinging stick, jumped on the roof and left.

Day 2, Day 3......

After being messy in the wind again, Xiao Qi finally couldn't bear it anymore, rolled his eyes, dodged the stick of the shopkeeper behind him, and jumped forward, dragging the cement on the ground until he reached the door of Albert's house.

Of course, the restaurant owner also repaired the concrete floor for four days in a row.

On the fifth day, finally, the kind lady reminded this person who walked without regard to the left and right, so that Xiao Qi's plan finally succeeded.

Fortunately, Mrs. Wise made this decision, otherwise Xiao Qi might have sealed the door of Albert's house with cement today.

That night, Albert's piano sounded a little longer than an imperceptible one, as if it was carefully scrutinizing his mind with every note, and vibrating his nerves.

Why is the photoelectric effect based on the frequency of light?

Light, is a wave, a continuous wave.

It's like a line, a continuous line.

The sound of the piano, with its beautiful kneading, like a piece of silk, slowly sank to the bottom of the sea with a shimmering blue light.

Frequency? Frequency is just a property of light waves, and its frequency can be seen every cycle.

Every cycle?

Suddenly, the same footprints of the daylight appeared in Albert's head.

The piano begins again, opening more intensely than the previous movement.

Is a string of footprints ......?

Footprints?

The rhythm of the violin became more and more cheerful.

Albert noticed the "h" at this point, Planck's constant.

The thing that Planck preached that should not be used casually.

What if it is regarded as an indivisible quantum of light?

Light quanta, just like ...... It's like footprints.

Albert pulled the bow quickly, the sound so loud that the key hanging beside him resonated unconsciously.

The shape of the footprint, the information contained in it is the owner of the footprint, and the depth of the footprint can only reflect the amount of pressure.

The frequency of the light wave contains the information of the light quantum, and the intensity of the light wave is only the amount of the light quanta!

The sound of the piano stopped abruptly.

After the song is finished, the world floats.

On March 17, 1905, Einstein's paper "An Enlightening View of the Creation and Transformation of Light" was published, which is also known as-

The optical quantum hypothesis.

As a "very revolutionary" paper, this publication naturally caused an uproar among physicists.

However, Xiao Qi ignored these and took the fish that had just been stolen from the restaurant in his mouth, "Well, this is the last one." ”

Thinking like this, the long shadow melted into the shadows of the alley little by little.

However, Xiao Qi didn't notice that a shadow followed him into the alley.

"There should be another ...... next step No, two places to go. Xiao Qi walked silently with his head down, and said to himself, "I just don't know if there will be any forks?" ”

Suddenly, Xiao Qi sensed that something was wrong - it was too dark in front.

It seems like...... The walls here are heightened?!

At this moment, he felt a stick hit behind him again, the angle and speed were stronger than ordinary attacks, if it was before, Xiao Qi would never be able to dodge easily.

However, the "intimate interaction" with the restaurant owner every day made Xiao Qi keenly dodge this attack.

"Not really, right?" He thought to himself, isn't it just another fish, and it's not the first time.

Standing on the trash can in the corner, through the faint light, Xiao Qi saw a thin and blurred outline.

"It's definitely not that big guy." Xiao Qi immediately judged.

"Ahh Also, it would be too disappointing for me if it was that easy. From the vague outline came a clear juvenile voice.

"What are you going to do?" Xiao Qi let out a threatening roar, and at the same time really wanted to give himself a mouth, this open mouth, it was really wrong.

"No nonsense, someone wants your ring."

"I've never heard of such a request."

"So that guy found me."

"I don't know who you are, but do you know who I am?"

The boy spread his hands: "Anyway, you're a cat now." ”

As he spoke, the thin figure gradually approached.
