Working Earth Model

11.07.2002

I remember that Woland had a globe on which one could see in real time what was happening in different countries. A similar device was installed in the new Technology Museum in Tokyo.

The globe with a diameter of 650 centimeters and weighing 18 tons is covered with small square screens - there are 3715 of them in total, and each has 256 LEDs that allow you to display information that comes from satellites and weather stations.

Every three hours, a picture of cloud cover over the Earth is shown. At the request of visitors, you can see the changes in the cloud pattern over the past month. It is especially interesting to observe the passage of typhoons and cyclones. From time to time, the globe switches to display the concentration of carbon monoxide at an altitude of 6000 meters above the Earth. Low concentrations are depicted in shades of blue, dangerous ones in orange and red.

Twice a day, the globe shows the change of day and night: one hemisphere plunges into darkness, and the lights of large cities shine on it. The exposition is very popular with visitors.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

The best time for sound sleep 01.09.2016

Specialists from the University of Cambridge conducted a study involving more than 4 volunteers and found out that sleep on the night from Tuesday to Wednesday is the strongest, and the positive effect of such sleep on health is the most significant.

As part of the study, experts analyzed the subjects' heart rate indicators. Their optimal parameters fell precisely on the middle of the week, which scientists described as "the most suitable period for sleep."

Analysts noted that during this period of the week, people tend to consume the least alcohol and fatty foods, which can affect the quality of sleep.

Sleep is of great importance in human life, performing several important functions, such as: provides rest for the body, promotes the processing and storage of information, facilitates the consolidation of the studied material, restores immunity by activating T-lymphocytes that fight colds and viral diseases.
