As the saying goes, “Layers look lively, laymen look at the doorway”. In our daily life, there are often some popular sciences that involve professional knowledge. At first glance, they seem to be “tall”, but in the eyes of professionals, they are full of mistakes. A large chemical code that can be changed in less than a minute with a colored chemical solution… Knowing that netizens list a series of typical negative cases, causing netizens to madly vomit and view more than 100 million views. The reporter of “Yangtze Evening News” invited professionals in many fields to provide you with “the right way to open professional knowledge”.
One of the negative cases: tampering with the program
In film and television dramas, we often see such a picture. The reverse character tries to break a large system, so he hijacked the programmer who wrote the code and asked the programmer to “tamper with the program for me within a minute.”
Programmers are forced to frustrate and can only bluntly “fell their fingers.” Just a second before the anti-theft system of the program was about to start, the programmer finally successfully completed the task and took a long sigh of relief.
In a minute, can a programmer really be able to change the code at the speed of light? It’s not that simple. A university computer department teacher told reporters that these scenes in the film and television drama are understandably exaggerated. Generally speaking, to complete the coding of a large-scale system requires the cooperation of multiple positions such as product manager, architect, and programmer. It is not a “one-man show” for programmers alone. The product manager is responsible for understanding customer needs, the architect sets the framework of the code, and then the programmer “fills in” the code into the structure. “For example, in any App you see, the front-end and back-end codes are different, and the programmers responsible for writing the front-end code and the back-end code are also different programmers. Therefore, a single programmer can crack all the code. This situation is basically impossible in the real world.” The computer department teacher added that programmers are not so good at “memory”. Even in the face of the code they write, they need to have memories and time. Therefore, within a minute, “lucky fingers are flying” is an exaggerated shot in film and television dramas.
The second case of the reverse case: clothing cutting “all inclusive”
Costume design is also a bridge that appears in high frequency in all kinds of film and television dramas. The costume designer who just debuted pointed a pair of skirts at the model’s body with scissors, and the passers-by A, B, and C all marveled: “This will be a masterpiece that shocked the world!” The rich and experienced designer aimed at the male protagonist to do three-dimensional cutting, and holding the needle thread was another violent piercing. Netizens who know a little about clothing design can’t help but “roar”: “Is there really no such thing as a pattern designer? In addition, aren’t senior designers afraid to tie real models into showers?”
Regarding the concepts of “printer” and “three-dimensional cutting”, professional teachers in the Department of Fashion Design obviously have the most say. Teacher Chen Fei from the Department of Fashion Design of Nanjing Art Institute told reporters that the process of designing and making plates is a very important process. The concept of pattern making is to transform the designer’s drawings into samples, and it takes a long time to accumulate this step. A good pattern designer can present the designer’s intention to the most ideal state. Another proper term for three-dimensional clothing design is “three-dimensional cutting”, which is a styling technique that allows designers to give full play to their creativity. Chen Fei said that most of the three-dimensional cutting is to cut and design on the human platform. Its operation method is to directly cover the fabric on the human platform, and make pre-conceived clothing through technical methods such as splitting, folding, shrinking, and stretching. Styling, then remove the cut fabric pattern from the table and make plane corrections, and convert to get a more accurate and decent paper pattern, and then make clothing. The process of three-dimensional cutting on the human body does use tools such as scissors and bead needles, but it is definitely an exaggeration to say that it is “sprayed into a shower”. The three-dimensional cropping shown in the film and television drama does not exclude the exaggerated component for the picture effect.
The third case of the reverse case: chemical experiment operation “roll up sleeves”
In all kinds of film and television dramas involving chemical experiments, you must have seen such a picture: a female experimenter with long hair wearing a shawl, wearing gloves, rolling up his sleeves, holding the bottleneck of the reagent bottle, and carefully watching the reagent bottle. Colored solution. Netizens who have a little knowledge of chemical experiments therefore started to madly vomit: “Are you really afraid of reagents splashing on your arms? In case it is a corrosive solution…”
Dai Jianliang, a coach of the Jinling Middle School Chemistry Competition, said that chemical experiments have strict requirements. Wearing goggles, wearing lab coats, and shawls in hair are basic rules. The goggles and long-sleeved lab coat can protect the eyes and arms, and tie up the hair for the sake of experimental safety to prevent the experimenter’s hair from falling into the solution when bending down.
In addition, the method of holding the reagent bottle, the placement of the alcohol lamp cap, etc. are all details that need to be paid attention to in the chemical experiment. For example, when picking up the reagent bottle, the label of the bottle body must be directed towards the palm of the hand. The alcohol lamp cap should not lie flat on the table, otherwise it will easily roll off, but should be placed upright.
Dai Jianliang also pointed out an experimental error that students are particularly prone to in the teaching of chemistry experiments: “Two students cooperated and poured the experimental liquid from the reagent bottle into the test tube. This approach seems to be in cooperation, but it is prone to danger In case one of them shakes his hand, the consequences are unbearable. Therefore, the pouring of the experimental liquid should be done by one person, and it is inappropriate for two people to cooperate.”
There are also these slots, which are also “intelligence quotient taxes.”
“Colorful roses”, neatly shaped like a honeycomb like a house, Guqin “four-handed play”… These objects or moving pictures that make you feel amazing are actually “IQ taxes”. Netizen “Gu Yu” has worked part-time in the flower shop, and has a deep understanding of the production of “Blue Fairy”: “On Valentine’s Day, we work overtime to dye roses that are not fresh (the blue dye does not know what it is. Things), and then sprinkle gold powder-the blue demon with flashing blind eyes appears. The cost of a few cents instantly turns over 20 times, and people are still rushing to buy…”
“Is it really so hard to check the materials carefully and then come back to shoot?” Among the long list of complaints, the only ones named by netizens were the two old handsome men Jincheng Wu and Liang Chaowei from the movie “Chibi”. Whether it’s the placement of the Guqin or the gestures of playing the piano, the professionals can’t fault it. Netizens sighed: “The more serious the crew, the better.”
