What animal does the word leather come from?

The word "skin" in ancient times sounded like "goat" and meant specifically the skin of a goat. Subsequently, the meaning of the word expanded and began to denote the cover of the body of both any animal and man.

Why do our milk teeth fall out?

All creatures on earth have teeth, be it a man, a cow, a horse, a dog, a cat or a mouse, but they all have precisely such teeth that best suit their lifestyle, way of eating and character in general.

In lower vertebrates, several changes of teeth occur during their life. For example, in a shark, fully grown and worn teeth simply fall out, like hair in mammals, and are replaced by new ones. Higher animals have fewer teeth, and the ability to grow new ones is more limited. A person's teeth change once in a lifetime - when his milk teeth fall out and new ones grow in their place.

As a result of evolutionary development, a person is at a stage when his teeth change only once. A human baby is born toothless. After six months of life, the first tooth appears in the middle of the lower jaw. Over the next two years, he grows twenty teeth. They are called milk teeth. Beneath them sits the second set of teeth, which begin to erupt after the age of six, and gradually, between six and twelve years of age, replace the milk teeth.

In addition, three more teeth, called molars, appear on both sides of each jaw in the depths of the mouth. Thus, in an adult, instead of twenty milk teeth, thirty-two teeth appear. A person is also characterized by what is called a "full set of teeth", that is, he has different types of teeth: incisors, canines, small molars and molars - all appear one next to the other. And they are all the same height and arranged in even rows.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
