Can anyone tell me three articles on the study of science

The ancient Xunzi "For Learning", the modern "Four Wheels of Learning", "Happy Learning", etc., there are too many, you can search on the Internet and read them in bookstores.

1. Learn to change the phenomenon of a person studying alone and cutting off the exchange of experiences with others.

2. Change those students who want to participate in the discussion but are afraid of saying the wrong thing and have psychological pressure, relax the psychological burden, and actively participate in the discussion; to make the physical and mental health develop in harmony.

3. Learn basic scientific knowledge, basic skills and methods through communication.

4. Learn to organize information with curves, histograms, fan charts, and concept maps.

5. Learn to design the best plan and observe the information.

6. Learn to determine the scientific plan, determine the task, select the material, determine the steps, and design the experimental record sheet.

In this carefully condensed book, nearly 100 influential and creative scientists are included. Here, we can see Newton standing on the shoulders of giants, Edison, the inventor, Qian Xuesen, the father of China's aerospace, and Stephen Hawking, a scientific wizard who is paralyzed and still researches, ......The stories of each of them are vivid and interesting to read, but my favorite is Faraday.

Although Faraday is not famous, his love of science is worth learning from each of us. Faraday had a difficult childhood: the son of a poor blacksmith, his father had a small income, was often sick, and had many children, so Faraday could not even eat enough when he was a child, sometimes he could only eat one loaf of bread a week, and because of such a family, he did not even go to elementary school.

Faraday sold newspapers at the age of 12 and worked as a book-bound apprentice at the age of 13, studying himself from the newspapers he sold and the books he printed, until he read the Encyclopædia Britannica. Faraday was particularly interested in chemistry books, so he used his meagre salary to buy chemicals and instruments, conduct various experiments, and record them on waste paper from the printing house to form a manuscript. In this way, when he was 22 years old, he was favored by the great British scientist David at that time, and became David's experimental assistant, and since then he has become a warrior who conquers the fortress of science and has become an excellent scientist.

So I have to learn from Faraday, don't just envy the goodness and advantages of others, and don't work hard.

"One Hundred Stories of Scientists" made me understand that every scientist has obtained his or her own ideals through his own unremitting efforts, and we must also use hard work to achieve our ideals.

From the stories of scientists, we can appreciate a lot of good qualities of scientists, and their research and pursuit of science and technology are very worthy of our learning.

I admired his patriotic enthusiasm and was touched by all the efforts he made for scientific research in China.

I learned that everything must fail first and then succeed.

Memory has always been considered a function peculiar to living things, especially higher organisms. However, materials scientists have discovered in their research that certain metals also have memory functions.

In the 60s of the 20th century, researchers in the U.S. Navy Ordnance Laboratory made a nickel-titanium wire from 55 nickel and 45 titanium. They wound the nitinol wire into a spiral coil, heated it to 150, cooled it, and straightened it. When the alloy wire was heated to 95 again, there was an incredible phenomenon - the wire automatically curled into the shape of the original spiral coil.

Once again, the researchers cooled and straightened it, and when it was heated to the same temperature, it returned to its original shape. Repeated experimentation and trial and error.

Later, scientists discovered that some other alloys, such as copper-zinc-aluminum alloys, copper-nickel-aluminum alloys, iron-platinum alloys, etc., also have this function of memory shapes, and they call such alloys "shape memory alloys".

This alloy with shape memory function can be widely used in many fields such as satellite antennas, aircraft hydraulic systems, pipe riveting, medical devices, etc. For example, the antennas made from them are usually very small when folded, but when the spacecraft goes into the sky, under the illumination of sunlight, the antenna will form a hemispherical shape with a diameter of several meters; The artificial bone rods made of them can rely on the body temperature of the person to assemble and fix the broken bones, which greatly accelerates the speed of fracture healing.
