About the scientific knowledge around us

1. Why does the milk have a skin after heating?

The skin floating on the surface of the milk is coagulated protein. Milk contains all the necessary nutrients for the growth and development of cattle, and protein is a very important nutrient.

Proteins solidify once heated. The reason why hard-boiled eggs solidify is because the protein in the eggs solidifies. Proteins in milk also coagulate when heated.

Protein, especially milk protein, will solidify as soon as it goes bad even if it is not heated. When protein goes bad, it produces acid, which can cause milk to curdle. Although yogurt coagulated with lactic acid bacteria can be eaten, it is better not to eat milk that has naturally deteriorated and coagulated because we don’t know what kind of bacteria it may contain that can cause illness.

2. What are matches made of?

There are two types of match rods: paper and wood. Wooden match rods are usually made of poplar, walnut, etc. Five or six kinds of firewood are used as raw materials. The round head of a match contains potassium chlorate, potassium dichromate, iron oxide, sulfur, rosin, manganese dioxide, antimony sulfide, etc., and sometimes some lead monoxide is appropriately mixed in. In order to facilitate the burning of the match, the rod next to the round head of the match is also coated with 1 cm long paraffin. On the paper matchstick, this part can be seen more clearly. The friction surface of the matchbox is coated with red phosphorus, antimony oxide, and sometimes manganese dioxide, silica sand, etc. as ignition agents. Press the match on the friction surface of the matchbox and strike it hard. The red phosphorus on the friction surface will burn first. This heat causes other oxidants to release oxygen in an instant, the paraffin on the rod is ignited, and the matchstick can burn smoothly.

3. Why does it make a "whooshing" sound when the wind blows

When strong wind hits slender things like wires or branches, it makes a "whooshing" sound. "The sound. The slender whip shakes violently in the air, and a vortex of air is formed behind the rod-shaped object, causing the air to vibrate and produce sound. The wind blows the branches for the same reason as the whip.

This kind of vortex will also form behind sharp angles or gaps when the wind blows, and make a "whooshing" sound, and the pitch will be different depending on the strength of the wind.

Composition on Technology

At the end of the 21st century, a high-tech aircraft - "Super One" appears in front of you. It is energy-saving, environmentally friendly and convenient. Let me introduce it now. There is a beautiful robot greeting passengers at the door of the plane. You don't need to use the plane ticket, just swipe your IC card at the entrance, because you have already booked the ticket online and the information has been stored and Sent to this plane.

When you sit in your seat, there will be an LCD screen in front of you. You only need to press it lightly to select the drinks and food you need, and the robot will deliver them immediately at lightning speed. .

You can check information on the Internet, play games while drinking a drink, and enjoy the beautiful scenery among the blue sky and white clouds through this screen. Now, we can use our cell phones at will on the plane. You can chat with your family and friends, and the plane is safe and everything is normal. "Super One" will stop and hang high in the air every time it reaches a station. Why is this?

Don’t worry, look: a space-time tunnel suddenly appears on the plane, leading all the way to the ground. As long as you walk in, the space-time tunnel will send you to the ground safely. The speed of Super One is very fast. It only takes half an hour for you to go from China to the United States. By the end of the 21st century, "Super One" has become the most common means of transportation. We can travel around the world on it, saving time and being comfortable. I hope everyone can go and have a seat!
