There’s also a $99 HomePod Mini, which goes up for preorder on November 6. There’s a lot to unpack here, though, with MagSafe for the iPhone and much more.

5G is coming to the iPhone

Apple seems quite bullish about 5G on the iPhones, noting that it will bring big new features to you, the end-user. And Apple has been partnering with Verizon on 5G, claiming the new iPhone will support Ultra Wideband. We’re left with some questions about support from other carriers and the slow rollout from Verizon on UWB, though, as we’ve noted with Samsung devices this year.

iPhone 12 is official

The iPhone 12 is real — and really colorful. It’s an all-new design keeping the aluminum frame with a glass back and a glass front for the screen. And, yes, it’s kind of a callback to the iPhone 4 and iPhone 4 flat design. It keeps the same 6.1-inch display size as the iPhone 11, but bezels are smaller. And OLED is coming to non-Pro iPhones: The iPhone 12 has a Super Retina XDR Display. It keeps the same 2,000,000:1 contrast ratio and has twice as

Apple event expected to bring 5G speed, smaller iPhone 12

(Reuters) – Apple Inc <AAPL.O> on Tuesday is expected to announce an iPhone 12 capable of tapping into faster 5G networks, a new feature designed to spur sales during the company’s busiest sales quarter.

The event is nearly one month later than normal and comes as the coronavirus pandemic has disrupted Apple’s well-oiled machine for designing and churning out its biggest-selling product.

Wall Street analysts widely expect Apple to launch four new iPhones at the event broadcast from its Cupertino, California headquarters at 1 p.m. ET (1700 GMT). (https://www.apple.com/apple-events/)

Two will be “Pro” models expected to have more camera sensors and a higher-quality display, with one coming in a large version for fans of big screens. In the middle is likely to sit an iPhone 12 with the broadest appeal: A big enough display and enough cameras to satisfy most of Apple’s fans, with a more attractive price.

Finally, analysts expect Apple to return to offering a smaller-screened model of its flagship phone after several years of relegating fans of smaller devices to its legacy models.

The iPhones announced Tuesday will test whether Apple can keep up that streak and ride a wave of consumer excitement around 5G wireless data networks, whose speediest variants outstrip their predecessors’ data rates multiple times over. Android devices from Samsung Electronics Co Ltd <005930.KS> and others have featured the new networking capabilities for months, and analysts say 5G phones are driving upgrades.

But Apple is in a delicate position of needing to excite consumers with 5G without setting them up for a disappointment: For many of its fans, it will be their first experience with 5G networks, which in the United States remain years away from delivering dramatic speed boosts for most consumers. Some analysts worry Apple will be selling a

Face ID in ‘iPhone 12’ may gain speed alongside camera enhancements

The “iPhone 12” could include a faster Face ID authentication than currently offered, a leaker claims, as well as an enhanced version of digital zoom that is assisted by advancements in computational photography.

In the days before Apple is anticipated to launch a new collection of iPhones, more leaks about what to expect are surfacing by various sources. One such leak from a well-established leaker centers around the photographic capabilities of the inbound models.

According to a series of tweets from “@Pineeaks,” a Twitter account operated by Max Winebach, Apple is still planning to ship a “dynamic zoning algorithm” for the TrueDepth camera array. The algorithm would enable the Face ID biometric authentication system to acquire a user’s face at a faster rate, which will shave off fractions of a second from the entire Face ID unlocking process.

The tweet list, spotted by MacRumors also claims Apple won’t be updating the design of the TrueDepth array at all for most of the models, with the exception of the “iPhone 12 mini.” For that model, Winebach claims the notch will be narrower but taller to accommodate the smaller display.

The digital and optical zoom capabilities will apparently get a “massive boost” for 2020, with a “significantly extended digital zoom” with improved distance and quality. The upgrade, which could enable a 10x digital zoom, would rely on the iPhone combining “several frames at different zoom levels, and stacking them together,” forming a hybrid of optical zooming and cropping, which then uses an algorithm to handle alignment

Scientists find upper limit for the speed of sound — ScienceDaily

A research collaboration between Queen Mary University of London, the University of Cambridge and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound.

The result- about 36 km per second — is around twice as fast as the speed of sound in diamond, the hardest known material in the world.

Waves, such as sound or light waves, are disturbances that move energy from one place to another. Sound waves can travel through different mediums, such as air or water, and move at different speeds depending on what they’re travelling through. For example, they move through solids much faster than they would through liquids or gases, which is why you’re able to hear an approaching train much faster if you listen to the sound propagating in the rail track rather than through the air.

Einstein’s theory of special relativity sets the absolute speed limit at which a wave can travel which is the speed of light, and is equal to about 300,000 km per second. However until now it was not known whether sound waves also have an upper speed limit when travelling through solids or liquids.

The study, published in the journal Science Advances, shows that predicting the upper limit of the speed of sound is dependent on two dimensionless fundamental constants: the fine structure constant and the proton-to-electron mass ratio.

These two numbers are already known to play an important role in understanding our Universe. Their finely-tuned values govern nuclear reactions such as proton decay and nuclear synthesis in stars and the balance between the two numbers provides a narrow ‘habitable zone’ where stars and planets can form and life-supporting molecular structures can emerge. However, the new findings suggest that these two fundamental constants can also influence other scientific fields, such

Physicists Calculate Upper Limit For Speed Of Sound In The Universe

KEY POINTS

  • Physicists tested sound as it travels through different materials
  • Sound can almost reach its upper limit when traveling in solid atomic hydrogen
  • The finding is vital in different fields of studies like materials science and condensed matter physics

Sound waves can travel to up to 36 kilometers or more than 22 miles per second when traveling through solids or liquids, a new study by a team of physicists revealed. The physicists said that their calculation could be the first known variables representing the threshold of sound waves.    

Before this new finding, the speed of sound was measured based on Albert Einstein’s theory of special relativity that identified sound waves threshold similar to that of the speed of light (300,000 kilometers or over 186,000 miles per second).

In a study, published in the journal Science Advances, the physicists said to calculate for the threshold of the speed of sound, they factored in the two dimensionless fundamental constants. These constants are the fine structure constant and the proton-to-electron mass ratio. 

The physicists explained that these two fundamental constants have already been used in calculations needed to understand the Universe. For instance, the dimensionless fundamental constants are also the basis for calculations of nuclear reactions, proton decay, and nucleosynthesis in stars. The balance between the fundamental constants could also point to the habitable zone where possible life forms could start outside Earth. 

With identifying the upper limit of sound, their finding also became significant in other fields of studies. Setting a known upper threshold of sound is particularly crucial to studies that test the limits of matter such as materials science and condensed matter physics.      

“We believe the findings of this study could have further scientific applications by helping us to find and understand limits of different properties such as viscosity
