How Einstein Lost the Battle To Explain Quantum Reality (nature.com) 1

Long-time Slashdot reader lee1 shares "an interesting essay on the history of orthodoxy in quantum mechanics," published this week in Nature.

Its title? "'Shut up and calculate': how Einstein lost the battle to explain quantum reality." [T]he views of Danish physicist Niels Bohr came to dominate. Albert Einstein famously disagreed with him and, in the 1920s and 1930s, the two locked horns in debate. A persistent myth was created that suggests Bohr won the argument by browbeating the stubborn and increasingly isolated Einstein into submission. Acting like some fanatical priesthood, physicists of Bohr's 'church' sought to shut down further debate. They established the 'Copenhagen interpretation', named after the location of Bohr's institute, as a dogmatic orthodoxy.

My latest book Quantum Drama, co-written with science historian John Heilbron, explores the origins of this myth and its role in motivating the singular personalities that would go on to challenge it. Their persistence in the face of widespread indifference paid off, because they helped to lay the foundations for a quantum-computing industry expected to be worth tens of billions by 2040...

The Einstein-Bohr dispute raised larger issues, according to the article. "What is the purpose of physics? Is its main goal to gain ever-more-detailed descriptions and control of phenomena, regardless of whether physicists can understand these descriptions? Or, rather, is it a continuing search for deeper and deeper insights into the nature of physical reality?

"Einstein preferred the second answer," the articcle notes — and concluded that quantum mechanics was incomplete: Unlike Bohr, Einstein had established no school of his own. He had rather retreated into his own mind, in vain pursuit of a theory that would unify electromagnetism and gravity, and so eliminate the need for quantum mechanics altogether. He referred to himself as a "lone traveler". In 1948, U.S. theoretical physicist J. Robert Oppenheimer remarked to a reporter at Time magazine that the older Einstein had become "a landmark, but not a beacon".

Subsequent readings of this period in quantum history promoted a persistent and widespread suggestion that the Copenhagen interpretation had been established as the orthodox view... When learning quantum mechanics as a graduate student at Harvard University in the 1950s, US physicist N. David Mermin recalled vivid memories of the responses that his conceptual enquiries elicited from his professors, whom he viewed as 'agents of Copenhagen'. "You'll never get a PhD if you allow yourself to be distracted by such frivolities," they advised him, "so get back to serious business and produce some results. Shut up, in other words, and calculate."

The book argues that actually the physics world suffered from "a subtly different kind of orthodoxy" — an indifference to "foundational questions" outside the mainstream — but that the "myth" motivated projects and experiments.

"Although the wider physics community still considered testing quantum mechanics to be a fringe science and mostly a waste of time, exposing a hitherto unsuspected phenomenon — quantum entanglement and non-locality — was not..."

Plunge in Storage Battery Costs Will Speed Shift to Renewable Energy, Says IEA (reuters.com) 20

"In less than 15 years, battery costs have fallen by more than 90%," according to a new report from the International Energy Agency, "one of the fastest declines ever seen in clean energy technologies."

And it's expected to get even cheaper, reports Reuters: An expected sharp fall in battery costs for energy storage in coming years will accelerate the shift to renewable energy from fossil fuels, the International Energy Agency (IEA) said on Thursday... The total capital costs of battery storage are due to tumble by up to 40% by 2030, the Paris-based watchdog said in its Batteries and Secure Energy Transitions report.

"The combination of solar PV (photovoltaic) and batteries is today competitive with new coal plants in India," said IEA Executive Director Fatih Birol. "And just in the next few years, it will be cheaper than new coal in China and gas-fired power in the United States. Batteries are changing the game before our eyes." [...] The global market for energy storage doubled last year to over 90 gigawatt-hours (GWh), the report said...

The slide in battery costs will also help provide electricity to millions of people without access, cutting by nearly half the average electricity costs of mini-grids with solar PV coupled with batteries by 2030, the IEA said.

The Los Angeles Times notes one place adopting the tech is California: Standing in the middle of a solar farm in Yolo County, [California governor] Newsom announced the state now had battery storage systems with the capacity of more than 10,000 megawatts — about 20% of the 52,000 megawatts the state says is needed to meet its climate goals.
Although Newsom acknowledged it isn't yet enough to eliminate blackouts...

Why Are Laptops Moving to Soldered RAM? (digitaltrends.com) 75

This year Dell moved to soldered RAM for its XPS 14 and 16, writes Digital Trends, which "makes it impossible to upgrade, or even repair."

"This was a big change from the past, where the XPS 15 and 17 were both celebrated for their upgradability." Of course, Dell isn't the first to make the transition. In fact, they're one of the last, which is what makes the decision so much tougher to swallow. Where soldered RAM was previously limited to just MacBooks and ultrabooks, it's now affecting most high-performance laptops for gaming as well. Even the fantastic ROG Zephyrus G14 moved to soldered memory this year.
After two months of research, the article's author acknowledges "there are tangible benefits to companies using soldered RAM, and all the people I spoke to while writing this agree that they outweigh the downsides, but how that applies to the end-user is a bit more complicated." If there's one thing and one thing only that soldered RAM is indisputably good for, it's saving space. [Haval Othman, a senior director of experience engineering at HP] explained the benefits, saying: "If battery life, mobility, form factor (thin and light), and power efficiency are my priority among other design choices, then my mind immediately goes to soldered RAM; because that's where soldered RAM can be beneficial and power-efficient, which will lead to longer battery life. Plus, it's going to give me more space on the motherboard, so I can design the product thinner and lighter. [...] If we want a thin product, the trade-off is soldering more of the devices onto the board."

This tracks. In a laptop, there's only so much space that can be used for components, and that free space grows smaller by the year to make ultrabooks possible. They're an industrywide trend that was first popularized by Apple, and the rest of the laptop manufacturing world quickly caught on. Each year, laptops are released thinner and lighter, and that means having to squeeze the components together in new, innovative ways... Soldering the memory down onto the motherboard means that it can be attached almost anywhere within the laptop instead of being slotted into a specific part of it. It effectively makes the laptop thinner by cutting back on the space that the RAM module takes up. The space saved by soldering memory can be used for other things, such as a bigger battery....

All three companies that I spoke to stress the form factor much more than any tangible cost benefits... Stuart Gill, director of global media relations, campaigns, and corporate content [said] "Both soldered and socketed RAM designs are now quite mature. As a result, we see no impact on the manufacturing process and, therefore, the cost to the consumer."

SO-DIMM chips also have "relatively limited bandwidth," according to HP's Othman, "while when you solder the memory chips onto the board, you can build it for a much wider bandwidth."

But the article ends by looking to the future. "The good news is that SO-DIMM memory might eventually be replaced by the CAMM2 standard." Recently approved by JEDEC, CAMM2 is said to be significantly thinner, and it'll be available both in soldered and non-soldered variants. Using CAMM2 will allow laptops to stack up to 128GB of RAM, and the frequencies are said to be going up, too. CAMM2 can also activate dual-channel memory with just a single module.

How Space Telescopes Spotted an Exoplanet With a Possible Hydrogen-Rich Atmosphere (nasa.gov) 5

In September NASA's James Webb Space Telescope investigated an exoplanet 8.6 times as massive as Earth, and "revealed the presence of carbon-bearing molecules including methane and carbon dioxide." Webb's discovery adds to recent studies suggesting that [planet] K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface... The planet's large size — with a radius 2.6 times the radius of Earth — means that the planet's interior likely contains a large mantle of high-pressure ice, like Neptune, but with a thinner hydrogen-rich atmosphere and an ocean surface. Hycean worlds are predicted to have oceans of water. However, it is also possible that the ocean is too hot to be habitable or be liquid.
NASA's announcement included some additional context: K2-18 b orbits the cool dwarf star K2-18 in the habitable zone and lies 120 light-years from Earth in the constellation Leo. Exoplanets such as K2-18 b, which have sizes between those of Earth and Neptune, are unlike anything in our solar system. This lack of equivalent nearby planets means that these 'sub-Neptunes' are poorly understood, and the nature of their atmospheres is a matter of active debate among astronomers. The suggestion that the sub-Neptune K2-18 b could be a Hycean exoplanet is intriguing, as some astronomers believe that these worlds are promising environments to search for evidence for life on exoplanets...

The abundance of methane and carbon dioxide, and shortage of ammonia, support the hypothesis that there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b.

Long-time Slashdot reader Baron_Yam noticed some sites resurfacing the news from September this week with more spectacular headlines, like "NASA discovered a planet twice as big as Earth with a gas that is 'only produced by life'" and "Discovery... sparks huge excitement among astronomers.

NASA's announcement? It's early Webb observations "provided a possible detection of a molecule called dimethyl sulfide. On Earth, this is only produced by life." The bulk of the dimethyl sulfide in Earth's atmosphere is emitted from phytoplankton in marine environments.

The inference of dimethyl sulfide is less robust and requires further validation. "Upcoming Webb observations should be able to confirm if dimethyl sulfide is indeed present in the atmosphere of K2-18 b at significant levels," explained Nikku Madhusudhan, an astronomer at the University of Cambridge and lead author of the paper announcing these results.

While K2-18 b lies in the habitable zone, and is now known to harbor carbon-bearing molecules, this does not necessarily mean that the planet can support life.

But it's all a validation of the new discoveries being made possible by space telescopes — new and old. "The first insight into the atmospheric properties of this habitable-zone exoplanet came from observations with NASA's Hubble Space Telescope, which prompted further studies..." "This result was only possible because of the extended wavelength range and unprecedented sensitivity of Webb, which enabled robust detection of spectral features with just two transits," said Madhusudhan... "These results are the product of just two observations of K2-18 b, with many more on the way," explained team member Savvas Constantinou of the University of Cambridge. "This means our work here is but an early demonstration of what Webb can observe in habitable-zone exoplanets."

[...] The team now intends to conduct follow-up research with the telescope's MIRI (Mid-Infrared Instrument) spectrograph that they hope will further validate their findings and provide new insights into the environmental conditions on K2-18 b. "Our ultimate goal is the identification of life on a habitable exoplanet, which would transform our understanding of our place in the universe," concluded Madhusudhan. "Our findings are a promising step towards a deeper understanding of Hycean worlds in this quest."

Pegasus Spyware Used on Hundreds of People, Says Poland's Prosecutor General (apnews.com) 14

An anonymous reader shared this report from the Associated Press: Poland's prosecutor general told the parliament on Wednesday that powerful Pegasus spyware was used against hundreds of people during the former government in Poland, among them elected officials. Adam Bodnar told lawmakers that he found the scale of the surveillance "shocking and depressing...." The data showed that Pegasus was used in the cases of 578 people from 2017 to 2022, and that it was used by three separate government agencies: the Central Anticorruption Bureau, the Military Counterintelligence Service and the Internal Security Agency. The data show that it was used against six people in 2017; 100 in 2018; 140 in 2019; 161 in 2020; 162 in 2021; and then nine in 2022, when it stopped.... Bodnar said that the software generated "enormous knowledge" about the "private and professional lives" of those put under surveillance. He also stressed that the Polish state doesn't have full control over the data that is gathered because the system operates on the basis of a license that was granted by an Israeli company.
"Pegasus gives its operators complete access to a mobile device, allowing them to extract passwords, photos, messages, contacts and browsing history and activate the microphone and camera for real-time eavesdropping."

Behold the World's Largest 3D Printer (apnews.com) 17

They're calling it "the world's largest 3D printer," but also "the factory of the future" — not just a 3D printer, but a manufacturing system. It's the succcessor to a 3D printer that could create an entire house, cutting construction time and labor, according to the Associated Press. And this one "may one day create entire neighborhoods." It has a voracious appetite, consuming as much as 500 pounds (227 kilograms) of material per hour... The university wants to show how homes can be constructed nearly entirely by a printer with a lower carbon footprint. The buildings and construction sector accounts for roughly 37% of global greenhouse gas emissions, largely due to the production and use of materials such as cement, steel and aluminum that have a significant carbon footprint, according to the United Nations Environment Programme. Such printed buildings can be recycled, which is unique compared to current construction. "You can basically deconstruct it, you can grind it up if you wish, the 3D printed parts, and reprint with them, do it again," Dagher said before the event...

But it can be used for a variety of other creations and already has been used for a range of things, from boats to defense department structures.

The project is partly funded by the U.S. military, according to the BBC. "Maine University says it hopes the printer can be used to make affordable housing, as well as bridges, boats and wind turbines."

Why is South Korea's Military Set To Ban iPhones Over 'Security' Concerns? (appleinsider.com) 22

"South Korea is considering prohibiting the use of iPhones and smart wearable devices inside military buildings," reports the Defense Post, "due to increasing security concerns."

But the blog Apple Insider argues the move "has less to do with security and more to do with a poorly crafted mobile device management suite coupled with nationalism..." A report on Tuesday morning claims that the ban is on all devices capable of voice recording and do not allow third-party apps to lock this down — with iPhone specifically named... According to sources familiar with the matter cited by Tuesday's report, the iPhone is explicitly banned. Android-based devices, like Samsung's, are exempt from the ban...

The issue appears to be that the South Korean National Defense Mobile Security mobile device management app doesn't seem to be able to block the use of the microphone. This particular MDM was rolled out in 2013, with use enforced across all military members in 2021.

The report talks about user complaints about the software, and inconsistent limitations depending on make, model, and operating system. A military official speaking to the publication says that deficiencies on Android would be addressed in a software update. Discussions are apparently underway to extend the total ban downwards to the entire military. The Army is said to have tried the ban as well...

Seven in 10 South Korean military members are Samsung users. So, the ban appears to be mostly symbolic.

How Good is the Rabbit R1 Handheld AI Assistant? (cnet.com) 28

It's another speech-recognizing, AI-powered handheld device "about half the size of a phone," writes CNET. (Though the $199 device comes with a keyboard and a tiny 2.8-inch screen.) "The Rabbit R1 can identify items in its environment. Point it at a plant, and it can tell you what kind it is. Aim it at your lunch, and it can tell you what's in it.

"it also feels a bit like a novelty so far...." It can call an Uber, order dinner from Doordash, translate conversations, record voice memos, play songs from Spotify and more. Your phone can already do all of those things, but [CEO and founder Jesse] Lyu is promoting the Rabbit R1 as a faster and more natural way to do so... So far, the Rabbit R1 feels fun, fresh and interesting, but also frustrating at times. It intrigues me, but it also hasn't convinced me yet that there's room for another gadget in my life.... Many of the things it can do today feel smartphone-esque, like asking for the weather or playing songs on Spotify...

Visual search is the most interesting feature so far... It's pretty accurate for the most part so far. When I pointed it at my salad during lunch, it was able to tell me most of the ingredients. That's not what I asked. After all, who orders a dish without knowing what's in it? I asked the Rabbit R1 to tell me how many calories were in my lunch. While it couldn't provide the answer I wanted, I was impressed with its response... Overall, Rabbit R1's visual analysis worked pretty well for identifying things like plants and characters from pop culture. When describing my colleague's sneakers, the Rabbit R1 got the brand wrong...

So far, I've used the Rabbit R1 to take voice memos, translate speech from Spanish to English, and answer basic questions about things like weather forecasts. These features work as expected for the most part.

The article points out that Ray-Ban Meta Smart Glasses "also have multimodal AI, meaning the eyewear can 'see' what you see and tell you about it," and "you can already do something like this on your phone through Google's Gemini assistant on Android phones (or the Gemini section of the Google app for the iPhone).

"It's also very reminiscent of Google Lens, which has been around for years..."

Japan's Moon Lander Made It Through Another Lunar Night (theregister.com) 10

Japan's moon lander "has woken up again," reports the Register, "having survived three lunar nights." A post on social media from the lander's X account confirmed that once more, Japan's Smart Lander for Investigating Moon (SLIM) had defied the odds and snapped a picture of the lunar surface using its navigation camera. SLIM was revived a few weeks ago, after a second lunar night. However, with telemetry showing that some of the electronics (temperature sensors) and battery cells were malfunctioning, the chances of the lander making it through a third lunar night seemed remote.

Yet against all odds, SLIM has stirred once more on the lunar surface despite lacking heaters to keep its electronics warm.

What Happened After India Banned TikTok? (apnews.com) 92

What happened after India banned TikTok? The move "mostly drew widespread support" notes the Associated Press, in a country "where protesters had been calling for a boycott of Chinese goods since the deadly confrontation in the remote Karakoram mountain border region." "There was a clamour leading up to this, and the popular narrative was how can we allow Chinese companies to do business in India when we're in the middle of a military standoff," said Nikhil Pahwa, a digital policy expert and founder of tech website MediaNama. Just months before the ban, India had also restricted investment from Chinese companies, Pahwa added. "TikTok wasn't a one-off case. Today, India has banned over 500 Chinese apps to date."

At the time, India had about 200 million TikTok users. And the company also employed thousands of Indians.

TikTok users and content creators, however, needed a place to go — and the ban provided a multi-billion dollar opportunity to snatch up a big market. Within months, Google rolled out YouTube Shorts and Instagram pushed out its Reels feature. Both mimicked the short-form video creation that TikTok had excelled at. "And they ended up capturing most of the market that TikTok had vacated," said Pahwa.

TikTok is also banned in Nepal and Somalia, according to Mashable, and the Associaterd Press adds that it's now also banned in Pakistan, Nepal and Afghanistan "and restricted in many countries in Europe."

Their article concludes that "for the most part, content creators and users in the four years since the ban have moved on to other platforms." They quote one frequent TikTok user as saying they just switched to Instagram after the ban, and "It wasn't really a big deal."

Apple ID Lock-Out Affects Macs, iPhones, iPads, and iCloud Services (indiatimes.com) 32

An anonymous reader shared this report from the Times of India: Several Apple customers were inexplicably locked out of their Apple ID accounts Friday evening in a major service disruption, forcing them to reset their passwords across all devices and services. According to user reports on social media, the widespread outage began around 8 p.m. ET. People complained that they were abruptly signed out of their Apple IDs on Macs, iPhones, iPads, and other Apple devices.

When attempting to sign back in with their existing passwords, they received an error message preventing access... To regain access, users had to go through Apple's account recovery process to reset their Apple ID passwords. However, many reported difficulties even completing the reset process initially due to high demand...

The outage affected iCloud services like iCloud Drive, iMessage, FaceTime, and the App Store. Third-party apps and services that integrate with Apple ID sign-in were also disrupted for those impacted.

Russia Vetoes U.N. Resolution On Nuclear Weapons In Space (cnn.com) 138

This week Russia vetoed a UN resolution that proposed banning nuclear weapons in space, CNN reports.

But it all happened "amid U.S. intelligence-backed concerns that Moscow is trying to develop a nuclear device capable of destroying satellites." In February, President Joe Biden confirmed the US has intelligence that Russia is developing a nuclear anti-satellite capability. Three sources familiar with the intelligence subsequently told CNN the weapon could destroy satellites by creating a massive energy wave when detonated...

US Ambassador Linda Thomas-Greenfield said Wednesday's vote "marks a real missed opportunity to rebuild much-needed trust in existing arms control obligations." A US and Japan-drafted resolution had received cross-regional support from more than 60 member states. It intended to strengthen and uphold the global non-proliferation regime, including in outer space, and reaffirm the shared goal of maintaining outer space for peaceful purposes. It also called on UN member states not to develop nuclear weapons or other weapons of mass destruction designed to be placed in Earth's orbit....

Experts say this kind of weapon could have the potential to wipe out mega constellations of small satellites, like SpaceX's Starlink, which has been successfully used by Ukraine to counter Russian troops. This would almost certainly be "a last-ditch weapon" for Russia, the US official and other sources said — because it would do the same damage to whatever Russian satellites were also in the area.

The article notes that in March Russian President Vladimir Putin "told officials that space projects, including the setup of a nuclear power unit in space, should be a priority and receive proper financing."

A School Principal Was Framed With an AI-Generated Rant (cbsnews.com) 21

"A former high school athletic director was arrested Thursday morning," reports CBS News, "after allegedly using artificial intelligence to impersonate the school principal in a recording..." One-time Pikesville High School employee Dazhon Darien is facing charges that include theft, stalking, disruption of school operations and retaliation against a witness. Investigators determined he faked principal Eric Eiswert's voice and circulated the audio on social media in January. Darien's nickname, DJ, was among the names mentioned in the audio clips he allegedly faked, according to the Baltimore County State's Attorney's Office.

Baltimore County detectives say Darien created the recording as retaliation against Eiswert, who had launched an investigation into the potential mishandling of school funds, Baltimore County Police Chief Robert McCullough said on Thursday. Eiswert's voice, which police and AI experts believe was simulated, made disparaging comments toward Black students and the surrounding Jewish community. The audio was widely circulated on social media.

The article notes that after the faked recording circulated on social media the principal "was temporarily removed from the school, and waves of hate-filled messages circulated on social media, while the school received numerous phone calls."

The suspect had actually used the school's network multiple times to perform online searches for OpenAI tools, "which police linked to paid OpenAI accounts."

Boeing Accused of Retaliating Against Two Engineers in 2022 (reuters.com) 44

Reuters reports that America's Federal Aviation Administration "is investigating a union's claims that Boeing retaliated against two employees who in 2022 insisted the planemaker re-evaluate prior engineering work on 777 and 787 jets."

The employees' union "said the two unidentified engineers were representatives of the FAA, which delegates some of its oversight authority and certification process to Boeing workers." The FAA noted on Tuesday that in 2022 it boosted oversight of planemakers by protecting aviation industry employees who perform agency functions from interference by their employers. A December 2021 Senate report found "FAA's certification process suffers from undue pressure on line engineers and production staff."

"Boeing can tell Congress and the media all it wants about how retaliation is strictly prohibited," said SPEEA Director of Strategic Development Rich Plunkett. "But our union is fighting retaliation cases on a regular basis, and, in this specific case, Boeing is trying to hide information that would shed light on what happened...."

Last week, Boeing quality engineer whistleblower Sam Salehpour, who raised questions about Boeing widebody jets, told senators he was told to "shut up" when he flagged safety concerns. He has said he was removed from the 787 program and transferred to the 777 jet due to his questions.

Boeing has "zero tolerance for retaliation," according a statement quoted by Reuters, in which the company says they "encourage our employees to speak up when they see an issue. After an extensive review of documentation and interviewing more than a dozen witnesses, our investigators found no evidence of retaliation or interference. We have determined the allegations are unsubstantiated."

The union's version of the story? "After nearly six months of debate, the two engineers, with backing from the FAA, prevailed. Boeing re-did the required analysis." The two engineers were still Boeing employees, however, and Boeing management was not pleased. When they came up for their next performance reviews, the two engineers received identical negative evaluations... Even after the manager of the two engineers admitted that he had rated them both poorly at the request of the 777 and 787 managers who had been forced to resubmit their work, Boeing refused to change the engineers' performance evaluations.

At this point, one of the engineers left in disgust; the other filed a formal "Speak Up" complaint with Boeing.
