Wang Xizhi, a great calligrapher in Jin Dynasty, loved calligraphy since childhood. At the age of seven, I studied calligraphy with Mrs. Wei, a calligrapher at that time, and studied hard every day. When there is no ink and brush, he writes on his clothes by hand, sometimes in the sand with branches, and sometimes in the moonlight at night. According to legend, he practiced calligraphy beside Lanting Pool in Shaoxing, Zhejiang, and the water in the pool was dyed black by washing pens and inkstones. After twenty years of hard work, he finally became a world-famous calligrapher, and his works have been passed down through the ages.
The lotus flowers painted by Huang Yongyu, a famous modern painter, are highly praised. But who knows how many lotus sketches he has drawn? Even Huang Yongyu himself can't count. Once, he asked his son to count how many sketches he had drawn. My son came in bundles, each bundle 100, a total of more than 80 bundles. After more than 20 years of hard sketching, Huang Yongyu repeatedly learned the skills of drawing lotus flowers.
Absorb the strengths of each family and achieve mastery through a comprehensive study. Later, he painted lotus flowers with unique charm.
Einstein said: success = hard work+correct method+less empty talk. As long as you pay, you will get something. Hard work pays off. Let's make unremitting efforts for success and create tomorrow's brilliance.
1.1In September, 878, Edison decided to attack the fortress of electric lighting. He read a lot of books about electric lighting and made up his mind to make cheap, durable, safe and convenient electric lights.
He started the experiment with an incandescent lamp. Put a small piece of heat-resistant thing in a glass bubble, and when the current burns it to a white-hot level, it will give off heat and glow. His first thought was charcoal, so he put a small piece of charcoal wire into a glass bubble, and the glass bubble broke as soon as it was electrified.
"What is the reason?" Edison picked up the carbon wire broken in two and looked at the glass bubble again. After a long time, he suddenly remembered: "Oh, maybe it's because there is air in it. The oxygen in the air helps the carbon wire burn and makes it break immediately!" " So he used his own hand-made air extractor to extract the air from the glass bubble as much as possible. Once it is electrified, it will not go out immediately. But eight minutes later, the light went out.
In any case, Edison finally found that the vacuum state is very important for incandescent lamps, and the key is carbon filament, which is the key to the problem.
So what kind of heat-resistant materials should we choose?
As long as you have perseverance, you will succeed one day, just as the saying goes, "many things grind."
