This way, it's undoubtedly much clearer and more accurate than observing with the naked eye.
In a certain sense.
This is also the most fascinating aspect of physics as a discipline.
Sometimes you don't need equipment precise to the scale of femtometers or nanometers; the idea is the most important.
Like when Xu Yun was in school, there was an experiment that required simulating the oscillation of spider silk, but at the time, they couldn't find equipment with a suitable oscillation period.
As a result, a tomboy pulled out an X stick and a protective X device on the spot and perfectly simulated the necessary period data through a foam pad.
That incident became a legend at Ke Da, and even during reunions, Xu Yun and his classmates still talked about it.
Of course.
Xu Yun and his friends never really clarified one thing with that girl—later, they thought, actually using an electric razor would be about the same...
Ahem, back to the point.
