Textbooks should be hard to read

10.03.2011

It is generally believed that for a better understanding of the text being read, it should be large and clear. An experiment conducted at Princeton University (USA) casts doubt on this.

The participants in the experiment (28 people aged 18 to 40) were divided into two groups and given the same text to read, in one case printed in large black print, and in the other in small gray. Then, after a 15-minute rest, when the participants of the experiment were distracted by other tasks, they were asked to answer questions on the text.

It turned out that those who found it more difficult to read gave 86,5% correct answers, while those who read a clear text - only 72,8%.

The experiment was repeated in high school classes in chemistry, physics, English and history - with the same results. It turns out that it is better to print textbooks on gray paper in small, hard-to-read fonts.

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, ... >>

Philips smart door handle 21.01.2024

Philips Corporation has announced its latest development in home security - a smart door handle with innovative palm recognition technology. This cutting-edge device features a unique biometric system that identifies users by the vein pattern of their palms, reminiscent of the technology previously introduced in the LG G8 smartphone.

Philips' new pen with palm recognition technology represents a significant step forward in home security, promising to improve user safety and convenience.

The special feature of this lock is its folding sensor, which is activated when a hand approaches. Scanning a clear map of the veins in the user's palm allows the built-in sensors to easily and unobstructedly unlock the door when the hand approaches.

Philips claims that this smart door handle with palm recognition can completely replace traditional door locks. It provides control through a special application and voice commands using assistants such as Google Assistant.

The $360 Palm Recognition Smart Deadbolt is scheduled to launch in the first half of 2024, bringing a new level of security and convenience to home access.
