Long and short chalk

After school, the 506 room was in a state of turmoil, and it became empty. The birds seemed to be silent and the air could be heard.

At this time, the glass fiber blackboard with a green and radiant reflection was reflected in front of the classroom, and the body was cleaned and cleaned by the cleaners. Suddenly at the bottom of the blackboard, an irritating voice broke this rare silence. It turned out that a long chalk was laughing at a short chalk with only half a finger.

The long chalk is slender and the skin is flawless. Then he sneered at the short chalk and said: "Look at your short body, lack of bluntness, unsightly, only to be thrown into the trash can!"

I didn’t answer the short chalk, but I thought, “At least I have grown too!”

A single-digit scientist rushed to the door and put a lot of books on his desk and turned to the blackboard. He rubbed his hand and took a warm heat. He picked up the long chalk and started writing the formula from the upper left corner to draw the geometric figures. The powder on the pen has fallen, and the bottom edge of the blackboard is already white, and only half of the time is long.

The more mathematicians write, the more they work, the more they stop. In a blink of an eye, the blackboard is filled with white pen marks. He wiped the sweat and looked at the chalk on his hand, but where can he still see it? The white end of the finger is stained with chalk, but the pen body has completely disappeared and turned into a digital element on the board.

The mathematician who could rest his breath, staring at his own master, made only to hear a loud bang on the table. He pointed to the calculation in the center of the blackboard and shouted: "How can I make such a low-level mistake? Write one plus one minus one, the latter formula is all wrong! ”

The mathematician's anger grew, and he did not care. The chalk brush on his hand had whitened half of the blackboard. He just had to find the root chalk to continue writing, and he touched the bottom edge of the blackboard. The chalk couldn’t touch the palm powder. The enthusiasm was cold and cold.

Mathematics sometimes needs inspiration, and the inspiration flashes fleeting. If you don't hurry, you can't meet it even in ten or eight years. Then he angered at the edge of the blackboard and made the white dust around him, so he could not cough. Suddenly, the mathematician rushed forward and squatted on the light green ground covered with white dust. His face changed from melancholy to eyebrows. It took only a few seconds for him to hold a short white thing. It was that short chalk.

Originally, the short chalk was covered by the white dust shattered by the long chalk. The mathematician naturally couldn't detect it. Now he found that naturally he was overjoyed, and then he handed the pen to the front of the board and carefully calculated it. With only one meal time, the blackboard is full of calculations. This time, the mathematician repeatedly checked the number of times in his heart. After confirming the accuracy, he immediately raised his hand and shouted: "This is the next, the Nobel Prize in mathematics is not for me? Haha!"

After the short chalk was completed, the body disappeared seven or eight, but he was lucky than the long chalk. The remaining value of life was only the size of the rice grain. It was light and fluttering, and no one would notice it on the ground. I only heard the sound of a slap, the volume was so small that even the ants could not hear it, but? ? The short chalk particles have been stepped into powder by the mathematician, and a short burst of wind has completely dissipated.
