What animal has passed an IQ test with a score corresponding to the normal level of an adult American?

Gorilla Koko has been trained by scientists at Stanford University since childhood. She knew more than a thousand signs of sign language and was able to understand about two thousand English words, and the results of her IQ tests corresponded to the normal level of an adult American. Koko knew how to describe her feelings, swear and joke. For example, once she coquettishly called herself a "good bird", declaring that she could fly, but then admitted that it was for fun.

 Random interesting fact from the Great Encyclopedia:

Who founded the first zoo?

The zoo, as everyone knows, is a place where animals living on earth today are kept and demonstrated to visitors.

Why are wild animals kept in zoos? The most important reason is that everyone is interested in animals. Another reason is that scientists have the opportunity to learn a lot of important things by studying the life of animals. Watching how animals behave, what they eat, how they grow, you can learn a lot not only about them, but also about people.

So, the zoo is like a school for studying both animals and people. And, perhaps, this explains why the first zoo, about which we know something, was called the "knowledge park". It was founded in 1150 BC. e. Chinese emperor, and it had many kinds of deer, birds and fish. Although it was somewhat similar to modern zoos, there was one significant difference: it was probably not open to the public, but was kept for the entertainment of the emperor and his court.

Since it costs a lot of money to complete a zoo and maintain it, in ancient times only kings and the rich started them. Many of them owned collections of rare birds, fish and animals of all kinds.

The world's first real public zoo was opened in Paris in 1793. It was the famous "Jardin de Plante". It contained animals, a museum and a botanical garden.

The next big zoo was opened in 1829, in Regent's Park in London. Then came the Berlin Zoo, which was opened in 1844 and became one of the most remarkable in the world.

In the United States, the first zoo was opened in Philadelphia in 1874, followed by a zoo in Cincinnati the following year, in 1875.

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, ... >>
