Physicists Disagree Wildly on What Quantum Mechanics Says About Reality

Slashdot - Thu, 2025-07-31 16:06
A Nature survey of more than 1,100 physicists reveals fundamental disagreements about quantum mechanics' relationship to reality, despite the theory's century-long track record as one of science's most successful frameworks. The survey, conducted to mark quantum mechanics' 100th anniversary, found 36% of researchers favor the Copenhagen interpretation while 17% prefer epistemic approaches that treat quantum states as information rather than physical reality. Another 15% support the many-worlds interpretation. Researchers split evenly on whether a boundary exists between quantum and classical worlds -- 45% said yes, 45% said no. When asked about the wavefunction's nature, 47% called it a mathematical tool while 36% considered it a representation of physical reality. Only 24% of respondents expressed confidence their chosen interpretation was correct, with others viewing their preference as merely adequate or useful in certain circumstances. The survey contacted over 15,000 researchers whose recent papers involved quantum mechanics, plus attendees of a centenary meeting on Heligoland island. Despite quantum mechanics enabling technologies from computer chips to medical imaging, physicists remain divided on the physical reality underlying the mathematics.

Stack Overflow Data Reveals the Hidden Productivity Tax of 'Almost Right' AI Code

Slashdot - Thu, 2025-07-31 15:15
Developers are growing increasingly frustrated with AI coding tools that produce deceptively flawed solutions, according to Stack Overflow's latest survey of over 49,000 programmers worldwide. The 2025 survey exposes a widening gap between AI adoption and satisfaction: while 84% of developers now use or plan to use AI tools, their trust has cratered. Only 33% trust AI accuracy today, down from 43% last year. The core problem isn't broken code that developers can easily spot and discard. Instead, two-thirds report wrestling with AI solutions that appear correct but contain subtle errors requiring significant debugging time. Nearly half say fixing AI-generated code takes longer than expected, undermining the productivity gains these tools promise to deliver.

Australia Widens Teen Social Media Ban To YouTube, Scraps Exemption

Slashdot - Thu, 2025-07-31 12:00
An anonymous reader quotes a report from Reuters: Australia said on Wednesday it will add YouTube to sites covered by its world-first ban on social media for teenagers, reversing an earlier decision to exempt the Alphabet-owned video-sharing site and potentially setting up a legal challenge. The decision came after the internet regulator urged the government last month to overturn the YouTube carve-out, citing a survey that found 37% of minors reported harmful content on the site, the worst showing for a social media platform. "I'm calling time on it," Prime Minister Anthony Albanese said in a statement highlighting that Australian children were being negatively affected by online platforms, and reminding social media of their social responsibility. "I want Australian parents to know that we have their backs." The decision broadens the ban set to take effect in December. YouTube says it is used by nearly three-quarters of Australians aged 13 to 15, and should not be classified as social media because its main activity is hosting videos. "Our position remains clear: YouTube is a video sharing platform with a library of free, high-quality content, increasingly viewed on TV screens. It's not social media," a YouTube spokesperson said by email.

Peacock Feathers Can Be Lasers

Slashdot - Thu, 2025-07-31 09:00
sciencehabit shares a report from Science.org: Peacocks have a secret hidden in their brightly colored tail feathers: tiny reflective structures that can amplify light into a laser beam. After dyeing the feathers and energizing them with an external light source, researchers discovered they emitted narrow beams of yellow-green laser light. They say the study, published this month in Scientific Reports, offers the first example of a laser cavity in the animal kingdom. [...] Scientists have long known that peacock feathers also exhibit "structural color" -- nature's pigment-free way to create dazzling hues. Ordered microstructures within the feathers reflect light at specific frequencies, leading to their vivid blues and greens and iridescence. But Florida Polytechnic University physicist Nathan Dawson and his colleagues wanted to go a step further and see whether those microstructures could also function as a laser cavity. After staining the feathers with a common dye and pumping them with soft pulses of light, they used laboratory instruments to detect beams of yellow-green laser light that were too faint to see with the naked eye. They emerged from the feathers' eyespots, at two distinct wavelengths. Surprisingly, differently colored parts of the eyespots emitted the same wavelengths of laser light, even though each region would presumably vary in its microstructure. Just because peacock feathers emit laser light doesn't mean the birds are somehow using this emission. But there are still ramifications, Dawson says. He suggests that looking for laser light in biomaterials could help identify arrays of regular microstructures within them. In medicine, for example, certain foreign objects -- viruses with distinct geometric shapes, perhaps -- could be classified and identified based on their ability to be lasers, he says. The work also demonstrates how biological materials could one day yield lasers that could be put safely into the human body to emit light for biosensing, medical imaging, and therapeutics. "I always like to think that for many technological achievements that benefit humans," Dawson says, "some organism somewhere has already developed it through some evolutionary process."

CodeSOD: What a CAD

The Daily WTF - Thu, 2025-07-31 08:30

In my career, several times I've ended up being the pet programmer for a team of engineers and CNC operators, which frequently meant helping them do automation in their CAD tools. At its peak complexity, it resulted in a (mostly unsuccessful) attempt to build a lens/optics simulator in RhinoCAD.

Which brings us to the code Nick L sends us. It sounds like Nick's in a similar position: engineers write VB.Net code to control their CAD tool, and then Nick tries desperately to get them to follow some sort of decent coding practice. The result is code like:

'Looping Through S_Parts that have to be inital created For Each Item As Object In RootPart.S_PartsToCreate If Item.objNamDe IsNot String.Empty Then If Item.objNamEn IsNot String.Empty Then If Item.artCat IsNot String.Empty Then If Item.prodFam IsNot String.Empty Then If Item.prodGrp IsNot String.Empty Then 'Checking if the Mandatory Properties are in the partfamilies and not empty If Item.Properties.ContainsKey("From_sDesign") Then ' I omitted 134 lines of logic that really should be their own function Else MsgBox("Property From_SDesign is missing or empty.", MsgBoxStyle.DefaultButton2, "Information RS2TC") Exit Sub End If Else MsgBox("Property prodGrp is missing or empty.", MsgBoxStyle.DefaultButton2, "Information RS2TC") Exit Sub End If Else MsgBox("Property prodFam is missing or empty.", MsgBoxStyle.DefaultButton2, "Information RS2TC") Exit Sub End If Else MsgBox("Property artCat is missing or empty.", MsgBoxStyle.DefaultButton2, "Information RS2TC") Exit Sub End If Else MsgBox("objNamEn is missing or empty.", MsgBoxStyle.DefaultButton2, "Information RS2TC") Exit Sub End If Else MsgBox("objNamDe is missing or empty.", MsgBoxStyle.DefaultButton2, "Information RS2TC") Exit Sub End If Next

All of their code is stored in a single file called Custom.vb, and it is not stored in source control. Yes, people overwrite each other's code all the time, and it causes endless problems.

Nick writes:

I really wish we'd stop letting engineers code without supervision. Someone should at least tell them about early returns.

Google Tool Misused To Scrub Tech CEO's Shady Past From Search

Slashdot - Thu, 2025-07-31 05:30
An anonymous reader quotes a report from Ars Technica: Google is fond of saying its mission is to "organize the world's information," but who gets to decide what information is worthy of organization? A San Francisco tech CEO has spent the past several years attempting to remove unflattering information about himself from Google's search index, and the nonprofit Freedom of the Press Foundation says he's still at it. Most recently, an unknown bad actor used a bug in one of Google's search tools to scrub the offending articles. The saga began in 2023 when independent journalist Jack Poulson reported on Maury Blackman's 2021 domestic violence arrest. Blackman, who was then the CEO of surveillance tech firm Premise Data Corp., took offense at the publication of his legal issues. The case did not lead to charges after Blackman's 25-year-old girlfriend recanted her claims against the 53-year-old CEO, but Poulson reported on some troubling details of the public arrest report. Blackman has previously used tools like DMCA takedowns and lawsuits to stifle reporting on his indiscretion, but that campaign now appears to have co-opted part of Google's search apparatus. The Freedom of the Press Foundation (FPF) reported on Poulson's work and Blackman's attempts to combat it late last year. In June, Poulson contacted the Freedom of the Press Foundation to report that the article had mysteriously vanished from Google search results. The foundation began an investigation immediately, which led them to a little-known Google search feature known as Refresh Outdated Content. Google created this tool for users to report links with content that is no longer accurate or that lead to error pages. When it works correctly, Refresh Outdated Content can help make Google's search results more useful. However, Freedom of the Press Foundation now says that a bug allowed an unknown bad actor to scrub mentions of Blackman's arrest from the Internet. Upon investigating, FPF found that its article on Blackman was completely absent from Google results, even through a search with the exact title. Poulson later realized that two of his own Substack articles were similarly affected. The Foundation was led to the Refresh Outdated Content tool upon checking its search console. The bug in the tool allowed malicious actors to de-index valid URLs from search results by altering the capitalization in the URL slug. Although URLs are typically case-sensitive, Google's tool treated them as case-insensitive. As a result, when someone submitted a slightly altered version of a working URL (for example, changing "anatomy" to "AnAtomy"), Google's crawler would see it as a broken link (404 error) and mistakenly remove the actual page from search results. Ironically, Blackman is now CEO of the online reputation management firm The Transparency Company.

Voice Actors Push Back As AI Threatens Dubbing Industry

Slashdot - Thu, 2025-07-31 03:30
Voice actors and industry associations are sounding the alarm over the growing use of AI in dubbing, calling for increased regulations to protect quality, jobs and artists' back catalogues from being used to create future dubbed work. "We need legislation: Just as after the car, which replaced the horse-drawn carriage, we need a highway code," said Boris Rehlinger, a voice actor known as the French voice of Ben Affleck, Joaquin Phoenix, and Puss in Boots. "I feel threatened even though my voice hasn't been replaced by AI yet," he said. Reuters reports: In Germany, 12 well-known dubbing actors went viral on TikTok in March, garnering 8.7 million views, for their campaign saying "Let's protect artistic, not artificial, intelligence." A petition from the VDS voice actors' association calling on German and EU lawmakers to push AI companies to obtain explicit consent when training the technology on artists' voices and fairly compensate them, as well as transparently label AI-generated content, gained more than 75,500 signatures. When intellectual property is no longer protected, no one will produce anything anymore "because they think 'tomorrow it will be stolen from me anyway'," said Cedric Cavatore, a VDS member who has dubbed films and video games including the PlayStation game "Final Fantasy VII Remake." VDS collaborates with United Voice Artists, a global network of over 20,000 voice actors advocating for ethical AI use and fair contracts. In the United States, Hollywood video game voice and motion capture actors this month signed a new contract with video game studios focused on AI that SAG-AFTRA said represented important progress on protections against the tech.

Google's AlphaEarth AI Maps Any 10-Meter Area on Earth Using Satellite Data

Slashdot - Thu, 2025-07-31 02:52
Google today announced AlphaEarth Foundations, a new AI model that processes terabytes of daily satellite data to track environmental changes across the planet. The system, part of Google's broader Earth AI initiative, uses machine learning to compress satellite imagery into color-coded maps showing material properties, vegetation types, groundwater sources, and human constructions down to 10-meter resolution. The model uses a technique called "embeddings" that reduces storage requirements by 16 times compared to other AI tools Google tested, while delivering 23.9% higher accuracy than similar systems. AlphaEarth has already mapped complex Antarctic terrain and identified variations in Canadian agricultural land use invisible to direct observation. The technology currently powers flood and wildfire alerts in Google Search and Maps. Research organizations including Brazil's MayBiomas and the Global Ecosystems Atlas are using the system to analyze rainforests, deserts, and wetlands. The model integrates with Google Earth Engine, providing agencies like NASA and the Forest Service access to over one trillion annual data points for environmental monitoring and mapping applications.

Boring Company To Build Tesla Tunnels Under Nashville

Slashdot - Thu, 2025-07-31 02:10
Elon Musk's Boring Company plans to build a 10-mile underground transportation loop in Nashville connecting the airport to downtown, with private funding and a projected launch as early as fall 2026. "If that happens, Nashville would become the second city where The Boring Company has opened such a system, with the first being Las Vegas," notes TechCrunch. "The company has spent the last few years in Sin City digging and opening tunnels around the Las Vegas Convention Center, and claims to have given 3 million rides in Teslas to date." From the report: The project will be privately funded by The Boring Company "and its private partners," according to the Governor's press release, though those partners are not named. The Boring Company and local officials will now begin a "public process to evaluate potential routes, engage community stakeholders, and finalize plans for the project's initial 10-mile phase." Construction won't begin until the project clears the approvals process. But the governor's office said the first segment of the loop could be operational as "early as fall of 2026."
