The Pixel 3 XL has all the power you need. Not only were there no problems in the performance of the titles, but the high framerate accompanied by the beautiful display and stereo speakers of Pixel 3 XL allow you to enjoy an immersive gaming experience using the highest settings. © NextPitįinal Fantasy XV and Life is Strange proved to be as impeccable as Asphalt. We already noticed this situation during the trial period for our review of the Razer Phone 2.įinal Fantasy XV allows you to make the most of your hardware. This is probably done to ensure that all mobile gamers have the same experience, without being penalized for having an older smartphone. I'm absolutely convinced that these games are able to run at 60fps on most modern top-of-the-range smartphones, but are artificially limited to 20 or 30 fps via software. No problems with Hearthstone - the game manages to run perfectly even on mid-range hardware nowadays.įortnite and PUBG are in a different category. As I expected, the game was perfectly fluid and smooth, even if the loading times could sometimes be slightly longer than those on the iPhone X or the Note 9. There's no game that can bring Pixel 3 XL to its knees yetĪfter some small issues with Asphalt 9 - the app was initially not compatible from the Google Play Store, I finally managed to spend a few hours driving cars. We will examine this further in the full review of the Pixel 3 XL. Ice Storm Unlimited is the only test in which the device that does not score well enough, but this could again be due to software. The other results are in line, though slightly lower, with the other smartphones equipped with Snapdragon 845 CPU and internal memory type UFS 2.1. This is certainly a symptom of non-final software and I'm sure the problem will be solved by Google soon. Looking at the table above, you can see that in the PassMark Memory test the result is not only much lower than that of other 2018 flagships, but also about half of last year's Pixel 2 XL score. The benchmark tests we performed confirm, in part, the problems with RAM management that we hope will be solved with the update coming before the official sale of smartphones. The issue does not occur on the Pixel 2, which has 4GB of RAM, either - supporting the software problems hypothesis. In any case, the behavior observed on the Pixel 3 press devices can be caused by an early version of the software (the build installed on our smartphones with the number PD1A.180720.030 technically dates back to July despite patches in September). This is partly because there is no real need for it, but at a starting price of $799, Google could have put in a little more effort. It's true, 4GB of RAM on a flagship in 2018 is basically unheard of. A couple of international journalists documented and filmed an aggressive behavior in multitasking management on the Pixel 3, when compared to other devices such as OnePlus 6 that have twice as much system memory. The main complaint Google has to deal with does not concern the hardware used, but the lack of RAM - only 4GB is available on the Pixel 3. ![]() 100 days with the Pixel 2XL: so flawless it's boring.Just look at the incredible fluidity of the Pixel 2, which sports the even older Snapdragon 835 and is still more responsive than many smartphones equipped with the latest generation chip. However, this does not mean that the Snapdragon 845 will suddenly become less functional. New top-of-the-range smartphones are already expected to hit the market during the first quarter of 2019. Unfortunately, this chipset will soon be replaced by a newer version. The CPU is comprised of 8 cores (4x 2.8GHz Kryo 385 Gold and 4x1.7GHz Kryo 385 Silver) and runs at the nominal frequency - no overclocking or underclocking at Google. This is the best mobile chipset available at the moment, if we look only at the American companies. Just to recap, under the hood of the new Google Pixel 3 and 3 XL you can find a SoC Qualcomm Snapdragon 845 with an Adreno 630 GPU. Yes and no - it depends on your point of view. What matters, in the end, is how much you enjoy using your smartphone every day. Obviously, your performance expectations and experience will vary according to you daily use.

This is the story of one of the world’s largest and most unique fake news empires, and how it gave birth to what became the iconic hoax of the 2016 election. To try and identify the owner, BuzzFeed News followed a trail from the fake sites to a group of now-defunct websites about topics including nurses and photos of Jennifer Love Hewitt, and eventually to a house in the small city of Atascadero, California, where a man named Justin Smithson resides. Not surprisingly, the person behind one of the biggest fake news scams of all time prefers to remain hidden. None of the sites list an owner or company, and all of their domain registration records are private. ![]() Many of the fake stories identified by BuzzFeed News followed the exact same pattern: They falsely reported that a big celebrity was moving to a specific town or community. But a BuzzFeed News investigation has found that the site is part of one of the world’s most unique and ambitious fake news operations - a network of at least 43 websites that together have published more than 750 fake news articles. It has largely been overlooked as a player in the world of fake news, a flash in the ersatz pan. WTOE 5 News is no longer online, and its owner has never been identified. Yet little has been said - and is known - about the site that originated this massive fake news hit. That hoax has been pointed to again and again. That post has earned close to 1 million Facebook engagements and was the single biggest fake news hit of the election, according to a previous analysis by BuzzFeed News.Įnding the Fed’s copycat hoax has gone on to capture additional attention as concerns about fake news during the election have intensified. But the hoax did even better on Facebook when, in late September, the website Ending the Fed published a fake story with the exact same headline. To date, the hoax has registered over 100,000 comments, shares, and reactions on Facebook, according to data from BuzzSumo. The story also falsely declared that “news outlets around the world” were reporting the endorsement. It improbably quoted the pope as saying that the FBI’s inability to prosecute Hillary Clinton for her emails led him to endorse Trump. was barely two weeks old when it published the hoax story, “ Pope Francis Shocks World, Endorses Donald Trump for President, Releases Statement.” In early July, a website made to look like a real news organization published what would prove to be one of the biggest fake news hits of the US election. ![]() ![]() There are other issues as well, such as that it would require a complete rethinking of our models of the galactic magnetic field."įixsen agrees wholeheartedly. "The primary reason is that it would make our galaxy completely unlike any similar spiral galaxy, which as far as we can tell do not exhibit the sort of giant, spherical, radio-emitting halo extending far beyond the galactic disk that would be required. "However, I would say that this explanation does seem to be less likely. "I wouldn't quite say that scientists have largely ruled out the possibility of the radio synchrotron background originating from our galaxy," said Jack Singal, an assistant professor of physics at the University of Richmond in Virginia, who recently led a workshop on the matter. Īll About Space magazine takes you on an awe-inspiring journey through our solar system and beyond, from the amazing technology and spacecraft that enables humanity to venture into orbit, to the complexities of space science. This article is brought to you by All About Space. "The space roar is similar to this expected signal, but there doesn't seem to be six times more galaxies in the distant universe to make up the difference, which could point to something new and exciting as the source." "It has been known since the late 1960s that the combined radio emission from distant galaxies should form a diffuse radio background coming from all directions," Kogut told All About Space in an email. ![]() But because the "space roar" is caused by synchrotron radiation, a type of emission from high-energy charged particles in magnetic fields, and because every source has the same characteristic spectrum, pinpointing the origin of this intense signal is difficult. Scientists call the signal "radio synchrotron background" - background being an emission from many individual sources and blending together into a diffuse glow. "The signal also has a frequency spectrum, or 'color,' that is similar to radio emission from our own Milky Way galaxy." "It's a diffuse signal coming from all directions, so it is not caused by any one single object," said Al Kogut, who headed the ARCADE team at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The latter became apparent rather quickly. Since then, scientists have looked to see where the radiation is coming from while looking to describe the properties of the signal. So the surprise was gradually revealed over months." That said, the impact was still huge. "It then took months of data analysis to first separate instrumental effects from the signal and then to separate galactic radiation from the signal. "While it might make a good movie to see us surprised when we see the light meter pop over to a value six times what was expected, we actually spent years getting ready for our balloon flight and a very busy night taking data," said NASA scientist Dale J. It was then that the intensity of one particular signal became apparent, albeit over many months. By looking at all of the "light" and comparing it to a blackbody source, ARCADE was able to see the combination of many dim sources. This was different from typical radio telescopes, which observe and contrast two points in the sky. ![]() ARCADE was able to make "absolutely calibrated zero-level" measurements, which means it was measuring the actual brightness of something in real physical terms rather than relative terms. ![]() The fact that this fluid's in here now is resisting the motion You give it another nudge, it slows down and stops. ![]() It doesn't keep going, it slows down and stops. Now what happens is you take this lid, you go to slide it across again. And I'm gonna fill it to the brim all the way to the top. Let's say there is no resistance so that if I gave this lid a little nudge, it just keep moving Now, check out this lid that I can put on the empty box. Which shows how naïve we all are-what in the world is skin friction!? Internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation. Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body. Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces.įluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. You can't expect a simple equation to describe all instances of that behavior.ĭry friction resists relative lateral motion of two solid surfaces in contact. Basically electrons from different surfaces interact and create resistance. The force is really caused by quantum phenomena, the electromagnetic force. It's just that usually when you're talking about friction (such as air resistance) you don't usually think about layers of fluid but instead simplify the force as proportional to an object's velocity, such as F = k v or F = k v^2.į = μ N is just an approximation and only applies to dry friction. It may still be hard to believe there is zero resistance, but even if there was another resistance force, by definition it is not the viscous force, but some other force we had assumed didn't exist. The "inertial drag" has nothing to do with velocity, only acceleration, and therefore is not viscosity. But still, you can't blame the mathematics.īesides, if the board and water are already moving, there sure is no resistance. So the water increases inertia, but doesn't provide a resistance force.Įxcept with a depth of infinity the mass would probably be infinity too, so it would be impossible to drag the water (a = F/m = F/∞ = 0). If the board is 1 kg, the water is 2 kg, and the force pushing the board is 6 N, then acceleration is not 6 N / 1 kg = 6 m/s^2, as is the case when there is no water, but 6 N / (1 kg + 2 kg) = 2 m/s^2, with a = F/m. However, by dragging the water with us we need to conquer its inertia. There is no force preventing that because there is no "ocean floor" to provide the friction, and we are assuming there is no other resistance. I think if the depth were really infinity, there would be no friction, because we could perfectly well drag all that water with us. |
