Tell me about the interesting natural laws and phenomena you know.

In summer, neon lights flash in the city, but it is easy to attract flying insects. But if you look closely, you will find that there are many flying insects in some places, and there are few flying insects in some places. If you look closely, you will find that these flying insects will gather in groups at dusk, especially in the dry and hot dusk. That's why there aren't so many flying insects when the lights are on. One is time, "dusk" and the other is light. There are many flying insects in places with these two factors, so if you want to reduce flying insects, you should try to miss the "dusk" lighting, so as to avoid annoying flying insects.

In life, we take out the frozen meat and thaw it. Some people will put it directly in the basin and let it thaw slowly; Some people will put frozen meat in water and let it thaw naturally. Anyone who has many years of life experience will choose the latter, and thaw the frozen meat in water, because it is faster and more efficient. This is experience. So does he have a scientific basis? Answer: Yes, because water transfers heat better than air. or vice versa, Dallas to the auditorium Blacksmiths will put hot soldering irons in water to cool them, instead of letting them cool naturally in the air. The application principle is that the heat transfer of water is better than that of air.

Look in the mirror, if you want to be more real and see yourself clearly, then you should choose to stand closer, because the farther away from the mirror, the easier it is to get out of shape. In other words, standing 20 cm away from the mirror and standing 200 cm away from the mirror, you will find that there is a big gap between the two, and standing 200 cm away from the mirror is obviously out of shape. This is mainly because, in the mirror, you are an image formed by the reflection of the silver surface plated behind the mirror. If the silver surface is uneven or the glass thickness is uneven, it will be deformed. Deformable mirror, the farther away from the mirror, because of the principle of light amplification, the more light emitted deviates from the normal position, so the more deformed the mirror is. Hehe, that's the principle of mirrors.

There are thousands of quartz clocks hanging at home, but once the battery is dead, no matter who makes the quartz clock, the second hand will stop at the position of "9". The quartz clock always drives the minute hand to rotate in seconds, and the minute hand drives the hour hand to rotate. Once the second hand stops, both the minute hand and the hour hand will stop. Once the battery is dead, the second hand usually stops at the position of "9", which is mainly because the second hand is most hindered by the large torque at the position of "9". Of course, if the quartz clock at home is hung a little askew, it may be in the position of "8" or "7". The principle is actually the same, that is, it is most hindered by the maximum torque.

In a word, in life, we can meet many natural laws, especially magical and interesting laws. As long as we carefully analyze and study, we can know their principles and correct treatment methods.
