Many people think physics is so esoteric and struggle to understand it, and cannot imagine how to employ their understanding in a useful way, Cao Zexian said.

They believe that only science and technology changes the way we live our day-to-day lives. "Yet the reality is that physics, in the form of technology that is deployed as an everyday product or service, can sometimes lead to amazing changes in our society altogether," Cao said.

From the loudspeaker to other electronic communications, all of them are involved with the techniques of physics such as acoustic load and radiation impedance.
