‘Complex numbers are not needed for quantum mechanics’: Physicists develop quantum model that uses only ‘real’ numbers for first time ever

For the first time, physicists have built a working version of quantum mechanics without complex numbers — numbers that have been considered essential to the theory for nearly a century.

Complex numbers combine a regular “real” number with an “imaginary” one — a multiple of the square root of-1, represented by the symbol i — into a single value, like 3 + 4i. The square root of-1 doesn’t correspond to any quantity you could count or measure directly (you can’t have negative one apple, for instance), which is why mathematicians call it imaginary.

Is AI making us stupid?

Not exactly—but how we use it matters.

A new Trends in Cognitive Sciences perspective argues that AI doesn’t inherently erode human intelligence. Instead, it highlights a well-known principle in cognitive psychology: cognitive offloading.

When we let AI perform tasks that require reasoning, writing, memory, or problem-solving, we reduce the amount of mental practice our brains receive. Like physical exercise, cognitive skills strengthen through use and weaken through disuse.

Skills: learned abilities such as writing, mathematical reasoning, diagnosis, or programming. These are most vulnerable if AI consistently replaces the learning process.

Basic cognitive abilities: foundational functions like working memory, attention, and executive control. Current evidence suggests these may be more resistant to decline, although more research is needed.

The key message isn’t that AI makes people “stupid.” Rather: AI can improve immediate performance. Overreliance may reduce long-term learning and skill retention.

AI is most beneficial when it augments human thinking instead of replacing it. This fits with decades of neuroscience showing that practice drives neuroplasticity. The brain adapts to the cognitive demands we place on it. If.

New test certifies quantum measurements that simpler methods cannot mimic

Proving that one quantum measurement is more powerful than another has long been difficult. Physicists from Heinrich Heine University Düsseldorf, Lund University and the University of Innsbruck have now developed and demonstrated a simple technique to certify that a certain class of measurements has properties that cannot be mimicked by simpler means. Their paper is published in the journal PRX Quantum.

Measurements are central to all quantum technologies. They are said to “collapse” the quantum state they act on, destroying its quantum properties and serving as the bridge to the classical world. Curiously, quantum mechanics allows for measurements that are more general than the ones we can directly associate with classical properties of a system.

These generalized measurements, or POVMs, short for Positive Operator Valued Measures, are not just a mathematical curiosity. They are known to improve performance in tasks like distinguishing between quantum states that would otherwise be indistinguishable, extracting more information from quantum sensors and securing quantum communication.

A Widening Anomaly Strains the Standard Model

Does a new measurement of a rare decay of the neutral B meson portend new physics?

In particle physics, ten years is a long time to sit with a puzzle. Since 2013, measurements of a rare decay—a neutral B meson (B0) transforming into an excited kaon (K*0) and a muon–antimuon pair (µ+µ –)—have stubbornly refused to match the predictions of the standard model, the theory that describes all known particles and forces [1]. Small enough to be dismissed at first as a statistical fluctuation, the pattern of discrepancies has grown with each new dataset into one of the most tantalizing hints of new physics in experimental particle physics. Now the LHCb Collaboration at CERN in Switzerland has published its most comprehensive analysis of the decay to date [2]. The result is clear: The anomaly persists. Encouragingly, the theoretical and experimental tools to understand it have never been sharper.

Within the mathematical framework of the standard model, the decay in question, B0 → K*0µ+µ–, can occur only through so-called higher-order electroweak loop diagrams in which a bottom, or b, quark transforms into a strange, or s, quark [3]. As a result, the decay is extraordinarily rare. In every million B-meson decays of all kinds, you can expect to find only one. That rarity makes the decay valuable: It could bear measurable imprints of particles beyond the standard model that contribute to the same loop processes but have so far escaped detection because they are too heavy.

George Dyson on Turing’s Cathedral: In Wildness Is The Preservation Of The World

Fourteen years ago, I sat down with George Dyson to talk about “Turing’s Cathedral.”

We talked about the machines that were coming. Now they are here.

Dyson watched the digital revolution get built from the inside. His father was Freeman Dyson. Einstein’s secretary was his babysitter. He grew up at the Institute for Advanced Study in Princeton, playing in the halls where Turing’s ideas became von Neumann’s machines.

He gave me a line I still cannot shake:

“There is no way to completely govern the digital universe. It will always be a wildness, not a bureaucracy or a national park.”

Read it again. Then look at every #AI governance debate happening right now.

Hy3 (free) — API Pricing & Providers

Hy3 is a 295B-parameter Mixture-of-Experts model from Tencent (21B active, 192 experts with top-8 routing) built for reasoning, agentic workflows, and real-world production use. It supports a configurable reasoning effort: a direct no-think mode by default, plus low and high chain-of-thought modes for complex math, coding, and multi-step problems. With a 256K context window, Hy3 targets long-horizon tasks, including improved coreference resolution, multi-turn constraint tracking, and stable tool-calling that generalizes across agent scaffoldings.

Tencent positions it as a reliable, cost-effective option across coding, document processing, financial analysis, game development, and frontend design, with a strong emphasis on grounded, anti-hallucination behavior that answers when grounded and flags when evidence is missing rather than fabricating.

7 Mind-Bending Physics Questions Sci-Fi Made Me Ask

Science fiction does more than imagine the future — it pushes the human mind to the edge of what it can understand.

In this video, we look at seven strange physics and philosophy questions inspired by sci-fi: Does the universe balance every action? What if our universe is not a closed system? If infinity is real, does everything eventually happen? When physics “breaks down,” is reality failing — or are we? Are human minds evolved to misunderstand the deepest universe? Is individuality just a useful illusion? And is math discovered, invented, or the best tool humans have for reaching beyond their own understanding?

Featuring ideas and examples inspired by Interstellar, Warhammer 40K, Interstellar, Star Trek, The Matrix, Dune, The Three-Body Problem, Arrival, Foundation, 2001: A Space Odyssey, The Expanse, Annihilation, Project Hail Mary, and more.

Science fiction begins where certainty ends.
