Apple Pencil

17.11.2015

Who needs a stylus for a tablet? No one needs! Under Steve Jobs, Apple strictly adhered to this principle. But still he appeared - Apple Pencil.

The $99 Apple Pencil is only compatible with the new 12,9-inch iPad Pro, starting at $799. These numbers alone can scare off a potential buyer, although Apple never ceases to amaze that even at such prices, their gadgets are sold out like hot cakes.

Technically, the Apple Pencil is hard to fault. The device is a so-called active stylus. This means that the stylus's conductive tip not only powers the capacitive touch display, but also transmits its position and position to the iPad at the same time, 240 times per second. This makes some features available.

For example, if you hold the stylus at an angle in pencil mode, you can use it for hatching as if you were using a real pencil. This is possible due to the tilt sensors built into the stylus. Of course, the gadget needs electricity to transfer data, so the Lightning connector is installed on its other end, which connects the stylus to the iPad.

A full charge of the built-in battery should last for twelve hours of battery life, and a 15-second recharge - for 30 minutes. For a stylus that is unlikely to be used all the time, this is quite enough.

However, just as well as Apple managed to integrate 3D Touch technology into its iOS 9 operating system, Apple Pencil support at the software level looks just as underdeveloped. Of course, the stylus works in the note-taking application, but its practical use is actually limited to this, so Apple has partnered with Adobe and Microsoft.

Adobe is integrating stylus support into iOS apps like Photoshop Sketch for drawing. In it, the user can experience all the possibilities of the stylus. These include, for example, a virtual ruler for drawing straight lines. Even fingers can be used as a ruler when touched.

Microsoft, in turn, equips its Office for iOS programs with an ink drawing function, through which you can supplement digital documents with notes and freehand drawings. Sounds practical, but if you open such a document on a non-iPad Pro, you'll end up with a graphic-heavy Word file.

Thus, Apple Pencil should be considered rather as a reserve for the future. If more apps and future iOS devices support this accessory, then it definitely has a right to exist. And now we can only guess who is in the target audience of the $99 stylus.

Designers and people in other creative professions work mainly with graphic tablets without a screen, using a PC monitor as a display medium. And for amateurs who need to quickly make notes and drawings, there is no need to spend money on such an expensive accessory.

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, ... >>

To drink or not to drink 02.05.2004

As soon as doctors began to say that moderate regular alcohol consumption improves the condition of the heart and blood vessels, it turned out that it harms the brain, and in addition - the blood vessels.

Employees of a psychiatric clinic at the University of the German city of Erlangen found that alcohol disrupts the processing in the body of the amino acid homocysteine, which is harmful to nerve cells. It is obtained in the process of metabolism as an intermediate product and is soon processed into harmless compounds. But alcohol blocks this transformation, and homocysteine ​​gradually accumulates in the brain tissue.

Occasional and infrequent drinking raises homocysteine ​​levels only slightly, but drinking regularly, even in small amounts, damages nerve cells. In addition, homocysteine ​​makes the walls of blood vessels looser, rougher, and then cholesterol plaques are more easily formed on them.
