Remember something
Today, in the room, I studied the change of the drug. There are sodium acetate and barium nitrate, and I want to see how it is at the right time.

Set the utensils, pour the solution of sodium acetate, and inject the agent of barium nitrate, and the two blend. Russia, I see things that separate from the liquid, gradually converge into deposits, white in color and uniform in quality, like flocs that first coagulate, and like frost falling on water. This is the precipitation of the phase of sodium acetate and barium nitrate.

I stare at this scene, thinking about the wonder of the sympathetic nature of matter. The change of chemistry is hidden in the end, but there is a strange phenomenon in the hair. Or like the change of mountains and rivers, although it is invisible in a moment, it can also become a great view when it accumulates over time. This precipitation of life, although the scene of a moment, but contains the mystery of material nature. From the knowledge, study the study of matter, when the microscopic knowledge, in the last place to see the universe, which is the true meaning.
