Britain's oldest rope

04.05.2010

Off the coast of the English Isle of Wight, at a depth of about 10 meters, among the remains of a prehistoric settlement discovered by scuba divers, a piece of rope 11,4 cm long was found. The rope was tied to wooden planks and, apparently, served as a brace during construction.

Its age is 8000 years, and it is made of plant fibers, the exact origin of which has not yet been established - perhaps these are nettle or honeysuckle fibers. The settlement was flooded during the rise of the sea level, when the glaciers melted at the end of the last ice age.

The oldest rope in the world was found in the desert on the Sinai Peninsula, where, thanks to the dry climate, it lay without rotting for 19 thousand years. Archaeologists say that the invention of the rope is comparable in importance to the further development of technology with the invention of the wheel.

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, ... >>

Smart home from IKEA 25.08.2019

IKEA said it is betting heavily on smart home technology as a new source of revenue. To do this, the company intends to invest in a new business unit "IKEA Home Smart", which will develop smart devices.

Company representatives say that in order to speed up the development process, it was decided to create a new division and invest heavily in its development. IKEA's smart home ambitions began as early as 2015 with the introduction of tables and lamps that, thanks to integrated wireless charging technology, could be used to recharge compatible devices. In 2017, the company began offering smart lighting systems to customers, and from September 1 of this year, smart blinds will go on sale in the United States. It is likely that IKEA will soon start producing more devices designed to create a "smart home".

According to the forecasts of the analytical company IDC, global sales of devices in this category in 2019 will amount to about 830 million units, in 2023 this figure will increase to 1,6 billion units. Therefore, it is not surprising that IKEA plans to expand beyond the production of ordinary home furniture.

The company believes that the joint work of IKEA Home Smart with other divisions will contribute to the digital transformation of the enterprise. The existing production will be improved and transformed, due to which new intellectual products will appear on the market.
