6) Chemist Mr. Fu Ying once said that only experiment is the "supreme court" of chemistry.

7) Mr. Dai Anbang, a famous chemist in my country, pointed out: Chemical education that only teaches chemical knowledge and technology is one-sided. Comprehensive chemical education requires not only teaching chemical knowledge and skills, but also training scientific methods and thinking.

8) Mr. Dai Anbang, a famous chemist in my country, said; The chemical laboratory should be the most effective and fruitful place for students to learn. To cultivate the quality of chemical science, we must not only impart knowledge, but also the most important thing. Develop students' intelligence. Intelligence factors include seven abilities: hands-on, observation, reference, memory, thinking, imagination, and expression. Thinking is the core of intelligence factors. All the above-mentioned quality factors can be trained to a certain extent in chemistry experimental teaching, and non-intellectual factors are also increased. ?

9) Mr. Dai Anbang, a Chinese chemist, pointed out: ?Chemical education that only imparts knowledge and technology is one-sided. Comprehensive chemical education requires not only imparting chemical knowledge and skills, but also training scientific methods and thinking. To cultivate scientific spirit and moral character, students are the subject of learning in chemical experiments. They conduct experiments under the guidance of teachers and are trained to use experiments to solve chemical problems, so that multiple intellectual factors can be developed. Therefore, chemical experiments are a kind of comprehensive chemical education. The most effective form of teaching. ?

10) Nobel Prize winner, Chinese-American Professor Zhengdao Li said it well: ?Experiments will not serve national defense in any way. ?

11) Science has no national boundaries, because it is a wealth that belongs to all mankind and a torch that illuminates the world, but scholars belong to the motherland. ?Pasteur (microbiologist, chemist)

　12) Genius only means lifelong unremitting efforts. ?Mendeleev (Russian chemist)

13) I hope that you, the younger generation, can also be like candles that illuminate people, have some heat and some light, and be loyal and loyal to the greatness of mankind. Contribute your strength to the cause. ?Faraday (British physicist and chemist)

14) ?Chemistry? The key to human progress Seaborg (famous American chemist and Nobel Prize winner in Chemistry).

The story of the chemist Sholema

1) The communist chemist Sholema. When Karl Sholema was still alive, the great His revolutionary mentor Engels praised him this way: This friend is both an excellent communist and an excellent chemist. ?After Scholeima's death, Engels wrote a biographical eulogy for him, making a comprehensive evaluation of his life. Why did Scholema receive such a high evaluation from Engels?

2) From apprentice to chemist

3) Karl Schlema on September 30, 1834 Born in a family of handicraft workers in Darmstad, Black Forest, Germany. His father, John, was a poor carpenter, and his mother, Lot, was a simple housewife. They had nine children together, and Carl was the eldest child. In 1850, Carl tried to get an education at a vocational school in the city, but by 1853 he dropped out of school due to financial difficulties. He loved chemistry so much that he worked as an apprentice in a pharmacy. Because of his diligence and studiousness, he soon became the pharmacist's right-hand assistant. In 1856, he came to a pharmacy in Heidelberg as a dispensing assistant. At the University of Heidelberg, the famous chemist Bunsen was giving a lecture on chemistry, and Scholema tried his best to attend Bunsen's lecture. Bunsen's superb experimental demonstrations and vivid reports made Sholema yearn more for chemistry, and at this time he secretly made up his mind. Must be a chemist.

4) In 1859, relying only on the money he saved from his own livelihood, he applied for the Chemistry Department of the University of Giessen, chaired by the famous chemist Liebig. This was a holy place that young chemists around the world yearned for. Due to insufficient tuition fees, Sholema left school after only one semester. Fortunately, during this semester, due to his hard work, he completed the analytical chemistry course as the basis of experiments. Through study and training, he basically mastered the skills of chemical experiments. At the same time, during this semester, he also listened to the chemical history course of the famous chemical historian Copp, which initially developed his interest in the history of science. Leaving school and losing his job did not stop Sholeima from pursuing chemical science. At this time, Rothko, a professor of chemistry at Owens College in Manchester, England, was recruiting a private experimental assistant. After hearing the news, Sholema immediately rushed to the UK, leaving his motherland alone and coming to this industrial city in the UK. After hard work, he finally became Rothko's assistant. Experimental assistant. He is very satisfied here. Firstly, he can continue to study chemistry-related courses, and secondly, he can conduct more chemical experiments independently. From then on, Sholeima finally realized his long-cherished wish and entered the door of chemical research. He studied on his own and conducted research, and soon achieved many results.

5) In 1871, he was exceptionally elected as a member of the Royal Society. In 1874, he became the first professor of organic chemistry at Owens College. He settled in England for more than 30 years until his death in 1892.

6) The founder of organic chemistry

7) Scholema's most important contribution to the development of organic chemistry was the systematic study of aliphatic hydrocarbons. Starting in 1862, he first separated pentane, hexane, heptane and octane from coal tar and petroleum, carefully measured the boiling points and other physical constants of these fatty alkanes, analyzed their elemental composition, and determined Its vapor density gives its molecular weight. He then continued to conduct in-depth research on methane, ethane, propane, butane and octane. He also prepared and investigated the derivatives of these alkanes through halogenation, hydrolysis, oxidation, esterification and other reactions, such as halides, saturated monovalent Alcohols, fatty acids, aldehydes, ketones and esters, etc., have realized a series of organic synthesis. The basic research on this system has greatly enriched people's understanding of aliphatic hydrocarbons. Before him, chemists had only studied individual and lowest alkanes, and people's understanding of aliphatic hydrocarbons was scattered and irregular. It was Sholema who pioneered the systematic study of aliphatic hydrocarbons, including higher hydrocarbons. It can be said that our knowledge about aliphatic hydrocarbons today was originally provided by Sholema. In order to understand and master the systematic knowledge of aliphatic hydrocarbons, Sholema not only put in hard work, but also took great risks. Since the knowledge of various aliphatic hydrocarbons is still blank, explosion accidents are inevitable during experimental research.

In this regard, Engels described Sholeima and said: "At that time, he often came to see me with blood spots and scars on his face." Working with aliphatic hydrocarbons was no joke; these mostly-unrecognized substances kept exploding on his hands, leaving him with more than a few glorious scars. It was only because he wore glasses that he did not lose his vision. ?

8) In 1357, the German chemist Kekulé proposed the theory that carbon atoms are four-valent and that carbon atoms can be connected to each other to form bonds. This theory is the basic theory of organic chemistry and a key point in the development of organic chemistry. However, the basic views and ideas of this theory were not immediately accepted by the majority of chemists, especially regarding whether the four valences of carbon atoms are equal and how carbon atoms are connected. The understanding is very inconsistent. The most troublesome thing is how to use this theory to explain the large number of isomerism phenomena in organic chemistry. At that time, some people believed that the four valences of carbon were different and used this to explain the isomerism phenomenon. Some people believe that there are two isomers in ethane, CH3-CH3 (methyl) and CH3-H (hydrogenated ethyl), and they generalize that CnH2n+2 alkanes should also have two similar series of isomers. For this reason, Sholema chose this topic as his research object. In the three years from 1862 to 1864, he conducted a large number of related experiments, and finally proved the identity of the four valences of carbon atoms with eloquent facts, overturned the above assumption about the existence of two structural series of alkanes, and clearly stated that because carbon Atoms with the same four valences are arranged differently with other carbon atoms to show different structures and produce isomerism. This work of Sholema played a positive role in the promotion and development of chemical structure theory, and also showed that Sholema was brave and innovative in scientific research. After clarifying the phenomenon of isomerism, Scholema turned to the study of the phenomenon of homologues. After solid and meticulous experimental research, he discovered a law, which Engels called the "boiling point law of CnH2n+2 series hydrocarbons". This law states that as the number of carbon atoms increases, the boiling point of alkane molecules gradually increases. Alkanes have higher boiling points than branched alkanes with the same number of carbon atoms. This law clearly shows that there is an inherent connection between the properties of organic matter and its structure, that is, the properties of organic matter are restricted by its chemical structure.

9) In addition, Sholeima has also made great achievements in research on fatty alcohols. He discovered a general reaction that converts secondary alcohols into primary alcohols, which some people call the Sholeima reaction. This reaction was later widely used in organic synthesis. In 1872, in order to facilitate teaching, he personally compiled an original "Chemistry Course on Carbon Compounds". This book is an excellent teaching book written entirely based on the theory of organic chemical structure and is very popular in Europe. In 1877, Scholema and Rothko collaborated on the Comprehensive Course of Chemistry. This is an encyclopedia-style chemistry textbook with 9 volumes in total. It was not published until the death of Sholeima. By the 1920s, it had been issued in 5 editions. When talking about this book, Engels pointed out: His masterpiece Chemistry Course, although co-authored by him and Rothko, was almost entirely written by him (this is known to all chemists). Considered to be the best work currently written in Britain and Germany. ?

10) ?Happy Farmer?

11) In the autumn of 1859, shortly after arriving in England, Scholema was introduced to the revolutionary mentors Marx and Engels. Frequent exchanges made them quickly become close friends. Xiao Laima was sincere and humble, humorous and optimistic. Marx and Engels liked him very much and gave him the nickname "Happy Farmer". Under the direct influence of Marx and Engels, Scholema began to study scientific socialism, and studied Marx's economic theory and historical theory. His political consciousness improved rapidly, and he soon became an early member and president of the Social Democratic Party, the party of the German working class. Members of the Communist International actively participated in the international labor movement. He served as a liaison between Marx and Engels many times and traveled to various European countries. Therefore, the leaders of various socialist parties in Europe knew Sholema. In the struggle between Marx and Engels and various opportunist schools, Sholema always stood firmly on the side of Marx and Engels. Xiao Rongma was never married during his lifetime. He devoted all his energy to his career. At the same time, he also donated most of his income to the party and comrades in difficulty, winning high prestige within the party. Engels highly praised Sholeima's noble qualities and said: "This is really one of the best people I have known for a long time." ?As a chemist, Sholeima is unique in that he can consciously apply the materialist dialectical perspective to observe and think when studying chemistry. He used the law of quantitative change to qualitative change to explain the phenomenon of homologues in alkanes. He foresaw the future prospects of artificially synthesized proteins based on the achievements and development trends of organic synthesis. In particular, he used historical materialism to seriously study the history of chemistry. His work "The Origin and Development of Organic Chemistry" published in English in 1879 was one of his attempts and an important achievement. The book was translated into French in 1885, and the author published a German version in 1889. The expanded English edition of this book was published in 1894 after the author's death, which shows how popular the book is. Originally, Scholema was going to write a general history of chemistry, but until his death, he had only completed a manuscript of six to seven hundred pages. Due to being too busy with work and his early death, this work with many new perspectives could not be published, which is a pity.

12) Through the study of the history of chemistry, Scholema clearly pointed out: The development of chemistry proceeds according to the laws of dialectics. ?He also used specific examples from the history of chemistry to illustrate the dependence and promotion of the development of science on production practice and the interaction between scientific theory and practice. When the German chemist Kolbe, who was deeply influenced by empiricism in the chemical tradition, opposed the stereochemical theory proposed by the Dutch chemist Van Hove, Scholema immediately expressed his support for the stereochemical theory and clearly stated: In order to develop natural Science requires new hypotheses: To establish new hypotheses, theoretical thinking is required. Some hypotheses may be wrong, but some can become scientific theories after being tested in practice. Chemists without theoretical thinking cannot become good chemists by relying solely on experiments. When emphasizing the importance of theoretical thinking, Sholeima also pointed out that existing theory should not be regarded as dogma, because it must also continue to develop according to the laws of dialectics. When new experimental facts conflict with existing theories, we should first respect the facts and propose new hypotheses, and we should not stick to the old theoretical framework.

13) In the last 20 years of his life, Sholema paid special attention to using Marxist philosophical perspectives to examine theoretical issues in natural sciences. He also specially opened two courses on the history of chemistry and the philosophy of chemistry at Owens College. These two new courses were very popular among students because they gained not only knowledge, but also wisdom and ideological enlightenment. From Engels's letter to Marx on May 30, 1873, we can know that Scholema participated in discussing Engels's writing plan for "Dialectics of Nature". Sholema wrote a note on the edge of the letter, indicating that he fully agreed with Engels's proposition that the object of natural science is moving objects. Objects and motion are inseparable. Natural science can only be investigated through the connection of objects and their motion. , can we understand the dialectical relationship of objects. This shows the close relationship between Scholema and Marx and Engels. In fact, Scholema was a consultant to Marx and Engels on scientific issues.

14) Just when the revolution and scientific undertakings needed more contributions from Sholema, ruthless lung cancer claimed his life. Sholema passed away on June 27, 1892, at the age of 58. Engels made a special trip to attend the funeral and laid a wreath at the tomb on behalf of the party's executive committee. Also attending the funeral were the entire Owens College faculty and many of his students. Later, in order to commemorate him, Owens College established the Carl Scholema Chemistry Laboratory as a permanent memorial.
