Chapter 18

Why is the super material glass, but we have the impression that glass is very fragile, because we don't see the true face of glass.

The story has to start with the three properties of glass,

First of all, no matter where the glass is hit, it is always broken in large pieces.

Stone seems to be used to this phenomenon, so people use brittleness to describe glass, but they still don't know why glass is so brittle.

Think about it carefully. This is really a difficult question to answer. I can ask the physics teacher in crying high school.

In fact, this characteristic of glass is still a focus in the frontier of physics.

Another unusual feature of glass is that it can be broken by sound.

Although there is a popular answer to this question because of resonance, it still cannot be explained. Sound can not destroy other objects in this way, even if the volume is raised any higher.

Moreover, the sound that can lead to glass breaking does not need too much energy, which points the spearhead of things. The glass may be broken on its own initiative.

It doesn't matter if you don't like this chapter. Anyway, just know that the man will develop a glass that has no defects and won't break.

This kind of problem was still an unsolved mystery at the forefront of science two years ago, and later made a breakthrough.

The plot can be exaggerated, but if it involves the technical level, it should be based on the cutting-edge science.

In addition, there are many online videos of Rupert's tears playing with the hydraulic press and being broken by bullets and pinching his tail.
