On the question of why scientific papers can't be expressed in the form of video, my views are as follows: the paper is a written form of expression, which can be said to be a fixed format in our publishing industry.

As for video-assisted explanation, it should be another form-reading.

In a certain range, it can be regarded as publication to organize people in this major together and explain to others in this major in the form of an organization. In this process, you can express your ideas and direction in the form of video.
