We think he destroys evil and corrects mistakes, and we are eager for a perfect expression. He is a different person, giving us a novel stimulus to the dull world, giving us a calm spirit and rational thinking. He is our role model, and the successful losers are the brave people we live by. Sherlock Holmes, an expert in the study William goodyear of Brazil, is a world-famous detective written by British writer Conan Doyle and a great man. He is brave and alert, and has excellent detective, analysis, judgment and reasoning skills. For example, at a glance, he can roughly guess someone's experience. He can recognize the gray, which is about a multiple of 1.4, and form something he is familiar with in the hands of various professionals. He can also judge the whereabouts of criminals by the mud spots on his trouser legs ... Sherlock Holmes' detective story inspired people, and even in physics, Einstein wrote this book. Evolution can use it as a start. He learned from Sherlock Holmes that scientists usually explore the mysteries of nature. People have always wondered why Sherlock Holmes: the intricate legends are fascinating and imaginative. What knowledge has he mastered? Conan Doyle gave us a strange and interesting short list in a research paper: the scope of Holmes' knowledge: 1-no knowledge, literature. 2 and philosophy-ignorance. 3-No knowledge, astronomy. 4, political knowledge, shallow. 5, botany, comprehensive knowledge, but root medicine and opium are well known. Generally speaking, there is a knowledge of chemicals, but it is practical for all. 6. The practicality of geology is often limited. But he can distinguish different soils. He came back to spot the mud splashed on his trousers and could give me the mud according to the firmness of the color. That's where it splashed in London. Eight, anatomical knowledge is accurate, but not systematic. 9-The literature is very extensive and breathtaking. He seems to know everything that happened in the last century like the back of his hand. From this picture, you can find that Holmes' knowledge of sword watch has its specific structure. Actually, this is the knowledge structure of detective talents advocated by Conan Doyle. Of course, due to the limitation of that era, Scientific Outlook on Development thought that it was far from the best structure today, but the important enlightenment he gave us was: First, to realize a function, there must be a corresponding structure. Different structures have different functions. Second, to have a single knowledge, you must have several knowledge. Knowledge is a broad goal. Third, among these knowledge, which knowledge should be fully mastered, which knowledge should reach a advanced level, which knowledge may be well known, etc., subject to the realization of functions. Fourth, knowledge is like a mixture in a warehouse, which is only accumulated by compounds with a certain structure. Fifth, realize that the function of knowledge can even be irrelevant. Sixth, knowledge is not all used for work, but also for enriching one's life, such as violin. 1 Sherlock Holmes' existence, reasoning Sherlock Holmes, according to his own narrative in The Real Road to Sherlock Holmes (about Sherlock Holmes), according to his mentor Dr. Bell (usually translated as a Chinese professor at school) and Xiong. However, what I don't seem to like is the bell. I also think this is misleading the real prototype. I think Locke, who is at rest, may live in London. Of course, Detective Sherlock Holmes may not be at 22 1B Baker Street, but he is probably a friend of Doyle's, and he also does similar rock and consulting detective work. "Besides, I think it is from the real prototype Sherlock Holmes. His personality probably won't be like Brett's, so it probably didn't work for him to ask Holmes, but he was always a genius in London. Detective, several of the most important from Locke's case-four signatures, Baskerville, a real case studying history and adventure may be a detective case record. And returned the case with new discoveries, about half of which were made up by Conan Doyle. Especially when the case reaches a new stage, it may be perceived that Doyle is fabricated. There are two possibilities, one is that the real detective is dead, or he really disappeared like Sherlock later. But when Conan Doyle signed the contract with Pen and had to serialize it, he had to give up halfway. The story of the adventure and return of ethnic minorities seems terrible, probably because there are no good cases to write. There is no direct evidence about this theory, but in recent years, many American researchers (such as Saul Cohen) have annotated Holmes in a paper. America) is a name Holmes Oliver Wendell Holmes, and Judge Jr is associated with his master. He said, master, cousins may be. We regard him as a perfect expression of our desire to eliminate evil and correct mistakes. He is an extraordinary man, who brings us new excitement in the boring world and calm and rational thinking to our biased mind. He is a successful model of our losers and a brave survivor of our self-imprisonment. William Goodholmes, an expert on Sherlock Holmes, is a world-renowned detective and an amazing wise man written by British writer Conan Doyle. He is brave and alert, with superb detective, analysis, reasoning and judgment skills. For example, he can guess someone's general experience at a glance; Regarding soot, he can identify 140 kinds; He is very familiar with the hand types of people in different occupations; Even if there are a few mud spots on the trouser legs, we can judge the criminal's behavior ... Sherlock Holmes' detective story is so inspiring that even Einstein couldn't help but use it as the beginning of the book when he wrote The Evolution of Physics. From the process of Sherlock Holmes' exploration, he talked about the general methods for scientists to discover the mysteries of nature. People must want to know: why can Sherlock Holmes have a unique eye in the complicated mystery and win by surprise? What knowledge has he mastered? Conan Doyle gave us a strange and interesting short list in the article "Study on Blood Characters": the scope of Sherlock Holmes' knowledge: 1, and literary knowledge-none. 2. Philosophical knowledge-none. 3. Astronomical knowledge-none. 4, political science knowledge-shallow. 5, botanical knowledge-not comprehensive, but know a lot about alfalfa and opium. Have a general understanding of poisons, but know nothing about practical gardening. 6. Geological knowledge-practical, but limited. But he can see different soil qualities at a glance. After he came back from a walk, he showed me the mud splashed on his trousers. He could explain where it splashed in London according to the color and hardness of the mud. 7, chemical knowledge-profound. 8, anatomical knowledge-accurate, but not systematic. 9, thriller literature-very extensive, he seems to know all the horrible things that happened in the last century. 10, playing the violin very well. 1 1, be good at using sticks and swords. 12. He has enough practical knowledge of English law. From this short table, you can find that Holmes' knowledge has its specific structure. Actually, this is the knowledge structure of detective talents advocated by Conan Doyle. Of course, due to the limitation of the scientific development level at that time, it is still far from the optimal structure today, but the important enlightenment he gave us is: First, to achieve a certain function, we must have a corresponding structure. Different structures have different functions. Second, only one knowledge is not enough. Must have a lot of knowledge. A wide range of knowledge revolves around a certain goal. Third, among many kinds of knowledge, which knowledge should be fully mastered, which knowledge should reach a profound level, which knowledge can be learned with a little knowledge, and so on. , subject to the need to realize the function. Fourth, this knowledge is not like a mixture piled up in a warehouse, but a compound organized according to a certain structure. Fifth, knowledge irrelevant to the realization of these functions can even be omitted. Sixth, not all this knowledge is for work, but some of it is also used to enrich one's life, such as playing the violin. 1, Sherlock Holmes' existential reasoning, Sherlock Holmes' prototype, according to Doyle's own narrative in Sherlock Holmes' The Truth, is based on his medical school tutor Dr. Bell (that is, Professor Bell, who is usually translated by China). However, even Bell himself doesn't seem to like this statement. Personally, I think Doyle misled the readers at the request of the real prototype. I think Shylock may really exist in London. Of course, the detective's name is not Sherlock Holmes, and he doesn't live at 22 1B Baker Street, but he is probably a friend of Sir Doyle, and he also does similar "consulting detective" work with Sherlock. In other words, I think Sherlock Holmes comes from a real prototype. His personality may not be as distinct as Sherlock Holmes's, and his deduction may not always work, but there is a genius detective in London. Sherlock's most important cases-The Four Signs, The Hound of the Baskerville, The Scarlet Letter and most of the cases in the history of adventure may be the case records of this real detective. More than half of the cases in The Story of the Return and The New Survey are probably made up by Conan Doyle. Especially in the late stage of the new investigation, Doyle may have fabricated all the cases. There are two possibilities. One is that the real detective died, or he really retired like Sherlock later. At that time, Conan Doyle signed a serial contract with the newspaper, so it was impossible to stop writing halfway and had to make up. And several seemingly bad stories in the history of venturing back are probably made up because there were no good cases to write at that time. There is no direct evidence for this theory. However, in recent years, many American researchers (such as Saul Cohen's Notes on a Paper about Sherlock Holmes) have associated Oliver Wendell Holmes Jr, an American judge whose surname is Sherlock Holmes, with the master. Said he and master might be cousins or something.
