Hey, let boys start the time challenge. The sound propagation speed in the "see" time of the Qiqu experiment is 340m/s, but how can we see the sound propagation?

At 20:20 last Saturday, the eighth episode of "Hi Fang Pai" broadcast by Zhejiang satellite TV king. Hi Fang boys Wang Jiaer, Ren Jialun, Chen Feiyu and Wei daxun continued to explore the unknown, put their eyes on the most commonly used "time" in life, embodied abstract time through a series of interesting experiments, and completed a wonderful journey of "seeing" time

The program practices the spirit of experiment and innovates science popularization. Mainstream media such as liberation daily, guangming.com, people's entertainment, Xinhuanet, China xiaokang.com, Shangguan news, and china.com have posted articles one after another, praising the program to show the beauty of science; "Audiovisual China" published an article praising "Hi Fang Pai" for disseminating "sophisticated" scientific knowledge as a "small Zhengda" popular science program; In addition, a number of large-scale film and television, science and Technology issued documents to call the program. The public praise of the program is rising, and the popularity is also high. After the broadcast of the eighth program, CSM city group received 2158 viewers, 158 hot searches on the whole platform, and the total number of topics related to Weibo reached 9.5 billion +. Hifang boys "saw" the passage of time with a funny experiment, integrated into traditional culture, and conveyed to the audience the desire to cherish good time

Traditional culture is combined with scientific exploration, and common sayings are interpreted to pay tribute to traditional culture

< /p > In ancient times, people used words such as "a cup of tea" and "a column of incense" to represent time, and words such as "a white horse crossing the gap" and "looking down" to indicate that time passed quickly. How long did these words mean? In order to test this problem, Heifang boys carried out a series of experiments based on the interpretation of these words

"White horse crossing the gap" means that the white horse galloped through the narrow gap, which means that time passed quickly. The members led the little white horse through the 10 cm wall gap, and finally calculated that the time from the appearance of the little white horse's head to the end of its tail was about 0.22 seconds; "Kungfu of a cup of tea" is usually used as a measure of time. By measuring the time from pouring tea to drinking into the stomach, members come to the conclusion that "Kungfu of a cup of tea" is about 7 minutes; "Between pitching" describes that things are progressing very fast. Only in the effort of lowering the head and raising the head, the members use instruments to calculate the time of the whole set of actions of "lowering the head and raising the head". Ren Jialun was assisted by the "plug-in" and won the title of "king of pitching". Finally, taking the average value of four people, the measured "between pitching" is about 0.4 seconds

Through the interpretation of Chinese traditional expressions such as "a column of incense" and "a cup of tea", Hefang boys truly restored the wisdom of ancient people and the breadth and depth of Chinese culture, integrated Chinese traditional culture into the experiment, and called on everyone to cherish time in busy life

Hey, put boys on the time challenge, funny experiment "see" time

The propagation speed of sound is 340m/s, but how can we see the propagation of sound? In order to "see" the spread of sound, Heifang boys was divided into two groups. They stood at both ends of 1700 meters long and completed a delayed chorus at a distance of kilometers. During this period, 85 volunteers stood at an interval of 20 meters. After hearing the sound, they raised their flags to see the path of sound transmission. In the experiment, the members at the starting point and the end point sang the words "Happy Birthday" and "happy" respectively. Because the sound propagation speed was 340 meters / second, a complete sentence of "Happy Birthday" could be synthesized at the end point after about 5 seconds. The members had a clear division of labor, tacit cooperation and quickly completed the experiment

Did you forget to bring your umbrella in rainy days get too wet walking or running? The members put on special environmental protection clothes to personally practice the answer to this question. They were divided into two groups. They used the two states of "strolling" and "big guy saving lives" to cross different "rainy days" at the same distance. After a heated "debate" competition, they concluded that running was less drenched than walking. In fact, under the condition of the same distance, the rain on the head and shoulders is the same every second when running. The faster you run, the less rain on the head and shoulders

The program is nearing the end. During this period, the joy and knowledge brought by "Hi Fang Pai" are infinite. As the old saying goes, "it is better to travel thousands of miles than to read thousands of books". Paying attention to every little thing in life, putting them into action and looking for the beauty in it are the energy that "Hi Fang Pai" hopes to bring to the audience

At the end of the exploration journey of "seeing" time, in the next issue, Heifang boys will focus on "brain", and what wonderful experiments will it bring us? Lock in the "Hi Fang pie" on Zhejiang satellite TV at 20:20 this Saturday, and continue to follow the fun of hi Fang boys to find the truth. Let's go together
