It is a weird thing to see a soliton wave on any water surface, which is not continuous and no nearby period. How can such wave live under the physical world?

What is Science on Tap?

An online symposium to share popular science with the broader range other than existing researchers. They were held weekly during 2021, and provided multiple topics from social science, biology, mechanical engineering, etc, mainly in Chinese. Xinyi serves as an active speaker, and she usually uses multiple sources to explain the topic. No recordings are available. These figures were used only for educational purposes.
