Water droplets are ordinary substances in life, but they are not simple. The philosopher Democritus said that people cannot step into the same river at the same time.

And his disciple Cradiru even said that one cannot even step into a river once. We know that rivers are flowing, and the rivers of the past are not the same as the rivers of the present.

Although this is true from a philosophical point of view, it is contrary to human knowledge. So, that leads to ethics.

Of course, a bit off topic. This famous quote by Democritus tells us that any object is in a state of change, and Zeno's immobility of the arrow is a purely philosophical contemplation.

In physics, objects are seen as carriers of energy. We all know that objects are real beings, while energy is non-real beings.

If the essence of an object is energy, then is the object real or non-real? A drop of water is naturally ordinary, but the changes it involves are not ordinary.

I have three questions. First, are all water droplets the same size in the world? Second, if a chopstick is wet and the chopsticks are diagonal, why does the water flow down the chopsticks and turn into water droplets and then fall?

Third, does a water droplet membrane exist? Each of the three questions has its own characteristics, and the three of you pick one at random. Mizukawa Mitsukawa is so Dese.

Liuzi Fenglai stood up abruptly Abra: It's definitely different. When it rains, there is light rain and heavy rain, and the small raindrops are naturally smaller than the large raindrops.

However, there is an upper limit to the size of the water droplets. When cold air meets hot air, it condenses. And in the air there are different condensation points, the water at different condensation points converges to form water droplets.

The number of condensation points determines the size of the water droplets. When chopsticks are dipped in water, the size of the water droplets is the same.

The difference is the speed of falling. Chopsticks go too deep into the water or people take the chopsticks out of the water too quickly, which can cause the water droplets to fall quickly.

Does the water droplet film exist? There must be, otherwise why wouldn't the water stop flowing for a short period of time? If it exists, then where is it?

A body of water theoretically has many water droplets. Not infinite, there are many. Doesn't that correspond to a lot of water drop films?

However, physicists do not seem to have discovered a water droplet membrane. I know that water has surface tension, and maybe the water droplet film is formed by it.

Surface tension is, as the name suggests, the force on a surface. I just tried it with a bowl and the water has a tendency to circulate.

The bottom surface of the bowl is concave upwards to reduce the surface tension. Therefore, the water droplets are also very small. In Spanish, agua can mean water or rain.

This is to say that the Yin Spaniards have long realized that the essence of rain is water. As a Spaniard, Dueñas naturally wanted to say something about Spain.

。 Why does water flow down the chopsticks? The first is stickiness. Because only a sticky object clings to the surface of another object towards the ground.

The second is that Duenias said that the water drops the film. That's right, the water drop film can be very long. Actually, the fountain pen is an example.

The ink travels from the tube to an extremely fine channel. The channel is directly connected to the nib.

Like water, ink has a tiny stickiness and a corresponding film. Because of this, when a person holds a pen and does not write, the ink does not flow out.

As soon as a person writes with a pen, a drop of ink is destroyed. However, new droplets of ink are formed.

In this way, the pen can write without causing a large amount of ink to flow out. That's what Margarita said.

When Mizukawa saw that the time had come, he said, "Okay, Diess Beishousi."
