How many legs do centipedes have?

The centipede is the household name for various types of arthropods, scientifically united in the superclass centipedes. Different species of centipedes have from 30 to 354 legs, and this number can be different even in individuals of the same species. Moreover, any centipede must have an odd number of pairs of limbs, so there may be 38 or 42, but not 40. In English, two names for these animals are established - centipede ("centipede" in Latin) and millipede ("thousand-foot "). Moreover, the difference between them is significant - centipedes are not dangerous to humans, and centipedes bite very painfully.

 Random interesting fact from the Great Encyclopedia:

Where was the first rice grown?

Rice is one of the most important and beloved foods. Did you know that the Chinese are used to greeting each other not with the words: "How are you?", but with the phrase: "Did you eat rice today?" That's how important rice is in their lives. Almost half of the world's population is partly or completely on a rice diet. In some Asian countries, each person eats up to 150 kilograms of rice per year.

Where rice was first cultivated by humans is not known, but it is possible that rice comes from southern India. We know for sure that it has been cultivated there for thousands of years. Rice spread from there to the East, to China, more than drinking millennia ago. Shortly thereafter, it spread to the West - to Persia and Egypt. In North America, rice was not known until the XNUMXth century. Although North Americans consume some rice, most people still prefer wheat.

Currently, in the United States, each person eats about two kilograms of rice a year. Rice without a shell is called brown rice. It is covered with a brown shell called bran. It contains the most vitamins and mineral salts. However, brown rice does not keep as long as white rice.

Most people prefer white rice - well threshed, processed and polished - to brown. In some countries, polished rice is enriched with vitamins and mineral salts. Rice is used not only for food. Rice flour is needed for the preparation of glue, starch, face powder. In Japan, China and India, rice is used to make wine.

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, ... >>

Flexible solar panels 31.03.2003

Canadian company Spheral Solar has developed flexible solar cells, a denim-like material that can generate electricity when exposed to sunlight.

This material can be placed on a surface of any shape, not necessarily flat. The efficiency of batteries made from this material is 11%, which is comparable to the efficiency of conventional flat solar cells, and much better than their flexible variants based on conductive polymers.

A relatively cheap new material is made from tiny silicon beads sandwiched between two layers of aluminum foil and sealed in plastic. Each such ball plays the role of a separate photocell, and the foil acts as electrical contacts.
