Essay on exploration 800 words, essay on the topic of exploration

My exploration. The autumn wind rises, the crab feet are itchy, and it is the golden autumn season of crab fat chrysanthemum yellow! On this day, my mother bought a plump hairy crab again.

I can't tell you how happy I am! I still thought in my heart: I can "kill again" today!

My mother quickly washed the hairy crabs with her teeth and claws, and tied them up one by one with hemp rope. From time to time, I urged my mother: "Hurry up, hurry up!"

Little gluttonous cat, it's going to be good right away! Mom replied as she put the crab in the pot. Through the transparent pan, I could see that the crabs were struggling desperately, but they calmed down after a while.

To my surprise, the shell changed from blue-black to orange-red. I wondered what was going on: why did the crab turn red when the shell was cooked?

I hurriedly asked my mother on the side: "Mom, do you know why the shell of the crab turns red when it is cooked" My mother said with a wry smile: "I'm sorry, I don't know."

You go ask Dad, he is our family's "Zhiduoxing", maybe you will know. So, I went to the study and told my father, who was immersed in the study of pulse circuits, the same problem. It turned out to surprise me:

Even my father, who usually calls himself a "jack of all trades", was choked by this question. He waved his hand and said to me, "When you grow up, go find out for yourself!"

I listened to my father's words, and my heart was cold, but I thought: If I don't experience wind and rain, how can I see that Rainbow Dad is right, I must find the answer through my own efforts! So, I opened "100,000 Whys" and carefully searched for the answer.

Ha! The hard work paid off, and I finally found the answer in the book "100,000 Whys".

Why do crabs turn red when cooked? It's about chemistry. It turns out that this boiled crab shell has a bright red pigment in color.

If the red shell of a crab is immersed in a chemical called acetone, the pigment will stain the acetone a beautiful orange red, and the shell will fade and lighten. Later, someone isolated this pigment from lobster eggs and called it astaxanthin.

Astaxanthin-containing animals are not only shrimp and crabs, but many crustaceans also use astaxanthin to dress themselves. Some small shells mainly contain fenocyanins, and some crabs contain pterenthin. These pigments, including astaxanthin, have a similar structure to carotene, and they are abundantly and widely distributed in nature.

The chemical name is ketone carotenoids, and they are the main components of the pigments contained in animals such as "shrimp soldiers and crabs".

The body color of living crustaceans varies depending on the species and the environment, but no matter what the body color of the living "shrimp soldier crab" is, as long as it is soaked or heated with formaldehyde, it will also turn red. This is because the pigment protein in the organism is denatured when it is heated, and the pigment that was originally bound to the protein "escapes" out, revealing the red color. In addition, after death, shrimp and crabs, due to the denaturation of proteins in the body, the pigment escapes, and the shell will also turn red.

Zi said: "Knowing is knowing, not knowing is not knowing, it is knowing." That is to say, whether you are a scholar of ancient and modern Confucianism, or a master of Chinese and Western knowledge, there is no end to learning, and there must be some knowledge that you have not mastered.

This requires us to have the spirit of being humble and studious, and not ashamed to ask questions, just like the geography teacher, seeking truth from facts, not knowing is not knowing, he did not prevaricate, let alone being strong and ignorant and self-deceiving. Instead, he had the courage to recognize his own shortcomings, and was determined to study and verify in many ways, and finally made up for this deficiency and made his knowledge to a higher level. And this teacher's spirit of facing up to problems and having the courage to solve them is a necessary condition for the development of all learning.

We have all read the allusions of Che Yin Nangying's painstaking reading, but how many of us have wondered how effective Nangy Ying's reading is? I'm afraid there aren't many people who can reply with a refusal answer. In fact, some people have done experiments to read books with firefly lighting on autumn nights, and the result is so bad that they can't see clearly, let alone read, but we don't know, and we think that there is really an allusion to fireflies as oil lamps, and it has been passed down from generation to generation.

It just so happens that the teacher has been teaching for 30 years, but he has never realized the difference between the big and small yellow croaker, which shows that the discovery of the problem is a certain opportunity, even accidental, which requires us to seek truth from facts.

Archimedes continued to explore all his life, even when he was already famous, he still kept checking calculations, questioning the results of his explorations, and his students asked him: "Teacher, you already know much more than us, why do you keep exploring and pursuing?" Archimedes drew a big circle, a small circle, and said:

This great circle is the scope of my knowledge, and the small circle is the scope of your knowledge, and the area of the great circle is larger than the small circle, so I know more than you. But in the outer part of these two circles, which are unknown to us, and the arc length of the great circle is longer than that of the small circle, so I have been exposed to more unknown territory than you, which is why I often doubt myself. "There is no end to learning, what we learn and know is just a drop in the ocean, if we deceive ourselves and others, and we don't know what we know, then there is no room for all science to develop and create.

We must have the courage to face problems, but also have the courage to solve problems, only the courage to face, can make our knowledge be further improved, only the courage to solve, in order to promote the progress and development of society.
