This is how China created an artificial Sun and Moon



In recent days, the Asian giant has announced two major milestones: the creation of an artificial Sun and Moon. And we are used to seeing how China builds hospitals or skyscrapers in a few weeks, but it never ceases to impress us that they have been able to build both an artificial Sun and an artificial Moon. Let’s see for what purpose they have created both.

Beyond being able to observe the Sun and the Moon from Earth or go to an observatory, we have astronomy programs to explore and satisfy that curiosity about the universe. Both the artificial Sun and the Moon created by China contribute to new technological advances that we will see next.

China’s artificial sun is already a reality

The main objective of the development of the artificial solar device is to create almost unlimited clean energy mimicking the natural reactions that occur inside stars.

“The recent operation lays a solid scientific and experimental foundation for the operation of a fusion reactor,” Gong Xianzu, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences, who led the latest experiment, told Xinhua.

In addition, he explained that the process at the atomic level that takes place in the reactor is similar to that which takes place in stars. “This releases a huge amount of energy without producing any kind of greenhouse gas or nuclear waste. So we could be facing a new source of energy for all of humanity.”

The East project (Experimental Advanced Superconducting Tokamak), an artificial sun that has multiplied by five the temperature of the Sun, for more than 17 minutes, reaching temperatures of 70 million degrees Celsius. The process does not require fossil fuels and leaves no residues, unlike the fission process. A project is close to 1,000 million dollars of investment and will continue in the experimentation phase until June.

Simulate lunar gravity on Earth

Not content with creating an artificial sun, a group of scientists from the China University of Mining and Technology has built a research facility capable of simulating the low lunar gravity.

Li Ruilin, the project’s lead researcher, says that “its effectiveness is so good that it can make gravity disappear without a time limit.” The idea of ​​creating an artificial moon in China arose from an experiment where scientists levitated a frog with magnets.

Let the artificial moon allow gravity disappears for an indeterminate time It allows to lengthen the training and simulation days of astronauts and teams prior to new lunar missions to solve problems and errors on Earth before they occur on the Moon.

“Some experiments, like a crash test, need only a few seconds in the simulator,” Li said. And he added in this regard: “But others, such as flow tests, measure how much a material will deform under constant temperature and stress, they can take several days and it is completely possible to do it”

Samsung cheated: the unique S95B QD-OLED TV turned out to be better than the company describes it



Samsung cheated the unique S95B QD OLED TV turned out to

Earlier this year, Samsung introduced the S95B QD-OLED TV, which stands out with its new panel and 144Hz support. And with the last point there is a nuance.

Samsung cheated: the unique S95B QD-OLED TV turned out to be better than the company describes it

The fact is that the frequency of 120 Hz is indicated on the Samsung website, and the company spoke about it during the announcement. However, the TV was found to be capable of running at 144Hz while maintaining 4K UHD resolution.

The author of the HDTVTest channel conducted a series of tests and determined that the TV can indeed operate at a higher frequency than stated. At the same time, it works in full 4K UHD without various tricks like reduced vertical resolution and does not miss a single frame. Is that in this mode the color depth is limited to 8 bits.

In order to get the TV to work in this mode, you will need a PC, since modern consoles only support 120 Hz. You also need a video card with HDMI 2.1 and an appropriate cable. The author tested the novelty with the GeForce RTX 3090. Everything worked fine, including G-Sync.

The Samsung S95B QD-OLED is therefore a unique TV not only because of its new panel, but also because of its support for 144Hz at 4K UHD resolution.

Xiaomi 12 Ultra camera options have appeared. They are fully consistent with the characteristics of the camera Xiaomi 11 Ultra



Xiaomi 12 Ultra camera options have appeared They are fully

It seems that, at least in terms of basic characteristics, the Xiaomi 12 Ultra camera will be completely identical to the Xiaomi 11 Ultra camera.

Xiaomi 12 Ultra camera options have appeared.  They are fully consistent with the characteristics of the camera Xiaomi 11 Ultra

prototype Xiaomi 12 Ultra

The source published a list of parameters, indicating a 120x zoom, a focal length range of 12-120 mm (equivalent) and an aperture range of F / 1.95-4.1. All this exactly matches the camera specifications of the current Xiaomi flagship.

That is, the periscope telephoto camera will still be able to provide 10x optical and 120x digital zoom and will be characterized by an aperture of F / 4.1, the main camera will have an aperture of F / 1.95, and the ultra wide-angle camera will offer a focal length of 12 mm equivalent.

But this does not mean at all that the Xiaomi 12 Ultra camera will not change. The company can change all three sensors while maintaining the above parameters. At a minimum, the device is credited with a new Sony IMX 989 main optical sensor with an optical format of about 1 inch.

It remains to be added that the source of information is the Digital Chat Station insider, who was the first or one of the first to correctly list the characteristics of many Xiaomi smartphones and not only.

AMOLED screen and no 5G. Motorola Moto G42 is getting ready for release



AMOLED screen and no 5G Motorola Moto G42 is getting

Motorola seems to have decided to take the bull by the horns and actively expand its smartphone lineup amid impressive sales growth in the US.

AMOLED screen and no 5G.  Motorola Moto G42 is getting ready for release

Motorola has already launched many new Moto G lineups, and the G42 is on the way. We have renders of the novelty and some characteristics. For example, it is known that the smartphone will receive an AMOLED screen, like the G41 and G52. For Motorola smartphones, this is a good option, as they have an unusually implemented Always On Display feature.

According to the FCC, the novelty will not have 5G support, so the smartphone can receive, for example, SoC Snapdragon 680 or MediaTek Helio G88/G96.

As for the design, it is as typical as possible for the current generation of Motorola smartphones.
