 In 1925, Werner Heisenberg developed the initial version of matrix mechanics, a theory focused on the observable, probabilistic aspects of quantum phenomena. He was not familiar with matrices at the time, but used a novel formalism that involved concepts later translated into matrix language by others. A key collaborator, Born recognized the mathematical structure of Heisenberg's work and, with Jordan, translated it into the language of matrices. Born had a strong background in mathematics, having studied under Jakob Rosanes at Breslau University. Born's former student, Jordan, worked with Born to formalize the theory, contributing significantly to the 1925 "three-person paper" that further detailed matrix mechanics.

 Számos hóbortja akadt, diákjai azonban rajongtak Öveges professzorért
Newton-törvények, molekuláris fizika, tehetetlenség és energia-megmaradás törvénye, sebesség, gyorsulás, tömeg, erő, munka – idegenül és unalmasan csengenek sokak számára ezek a fizikai szakkifejezések. A 125 éve, 1895. november 10-én született Öveges József professzor az egész életét annak szentelte, hogy megmutassa szeretett tárgya szépségeit, s hogy milliókkal szerettesse meg a fizikát. Az ízes zalai tájszólásban, egyszerűen és lényegretörően beszélő szerzetes-tanárnak a televízió jószerével egész Magyarországot az előadótermévé varázsolta.
Reverendás korcsolyás
Öveges József egy kis Zala megyei faluban, Göcsejben született a Millennium előestéjén, 1895. november 10-én. Felmenői apai ágon két évszázadra visszamenőleg népiskolai tanítók voltak, így Öveges sem sokat gyötrődött a pályaválasztás kérdésén. Eleinte édesapja kezei alatt tanult, majd annak halála után édesanyja – látván a gyermek szorgalmát – anyagi áldozatok árán is tovább taníttatta a család legidősebb fiát.
A győri bencés és a kecskeméti piarista évek után már 17 évesen belépett a piarista rendbe. Az I. világháború zavaros évei után Budapestre került, s párhuzamosan végezte el a hittudományi főiskolát és a Pázmány Péter Tudományegyetem matematika-fizika szakát, ahol az egyetem későbbi névadója, Eötvös Loránd tanította kísérleti fizikára. Kereken egy hónappal a végzetes trianoni béke után szentelték pappá.
A fizika iránt rendkívül fogékony, tehetséges fiút a később radioaktív izotópos kutatásáért Nobel-díjat elnyerő Hevesy György egyetemi tanársegédi kinevezésre terjesztette fel. A frissen végzett, fiatal középiskolai tanár először Szegeden kapott állást, ahol a történelemtől kezdve a földrajzon át mindent tanított, csak fizikát nem.
A nyári vakációkat mindig a Pákán lévő családi házban töltötte. A falubeliek gyakran láthatták, hogy a kissé bogarasnak titulált fiú még vasárnap hajnalban is úszni jár a malom alá, s egy könyvet mindig cipel a hóna alatt.
Gyermekei nem lévén, fizetését igyekezett a szegények megsegítésére fordítani: történt egyszer, hogy a 40 filléres mézeskalácsszív árát 1 pengőre „alkudta le”. A tátott szájú kereskedő és a többi árus még napokkal később is a matematikai ismeretek teljes hiányában szenvedő, „félkegyelmű legényen” mulattak. Később a fizetésének nagy részét és az 1948-ban elsők között elnyert Kossuth-díját is a falujabeli cigányoknak adta.
Tatai tanítói évei alatt, 1924-ben jelent meg első zsebkönyve, melyben száz oldalon keresztül mutatta be a tudományos szabályoktól a parasztregulákig az időjóslás módjait. A könyvkiadó csak úgy volt hajlandó megjelentetni munkáját, ha legalább 2000 biztos előfizetőt verbuvál hozzá. A szerző egy városi lapban „Adja el az esernyőjét és vegye meg Öveges József Időjóslás és időhatározás című könyvét” tartalmú hirdetést jelentetett meg, amivel bebiztosította írói karrierjét.
A tavak városa után Vácra került, de az 1930-as éveket már ismét Tatán töltötte. Tanítói stílusa ekkorra már végleg kialakult. Órái akár egy interaktív, szórakoztató színdarab, az osztály tagjainak lelkes közreműködésével zajlottak. Igazgatója egy óralátogatás alkalmával megjegyezte: „nem hittem, hogy ilyen tanárok is vannak!”

 Mateklecke 6078. - Káosz 8. rész
Ha egy biciklit meglökünk, de senki nem tartja kormányon, akkor a kereke nem egyenes vonalban gurul, hanem oszcillál (jobbra-balra kanyarodik), közben a sebesség lassul, a kilengés egyre nagyobb lesz, míg végül eldől.
A kép minden egyes fekete vonala egy-egy bicikli első kerekének talajon megtett nyomvonalát mutatja. Azért néz ki kaotikusnak, mert a bicikli pályája instabil, apró eltérések is egyre jobban felerősödnek.

A team of physicists in Germany has made a breakthrough that could redefine how we power our devices. At the University of Augsburg, researchers have built a room-temperature quantum battery that charges almost instantly and can hold its energy indefinitely. This innovation marks a significant leap beyond conventional batteries, which rely on chemical reactions and gradually lose capacity over time.
The quantum battery stores energy in entangled quantum states rather than through chemical processes. By using trapped ions inside a laser-stabilized electromagnetic chamber, the researchers achieved stable, coherent quantum states at room temperature, a feat that previously required ultra-cold environments. This makes the technology far more practical for everyday applications.
Thanks to quantum entanglement, all particles in the battery absorb energy simultaneously, a phenomenon known as quantum superabsorption. This allows the battery to reach full charge in microseconds without generating heat, suffering degradation, or losing capacity over time. Unlike traditional batteries, the energy remains stored indefinitely until needed and can be released instantly on command.
In laboratory tests, the first prototype, no larger than a grain of rice, powered a micro-robot for six continuous hours after just a 0.01-second charge. The device doesn’t overheat, uses no rare materials, and does not degrade over time, offering a clean, long-lasting, and high-density energy solution for the next generation of electronics.
While still in early stages, the implications of this technology are profound. Future applications could include powering smartwatches, drones, medical implants, or even satellites, all without conventional charging cycles. The development of larger quantum cells could transform energy storage, making “forever-charged” devices a real possibility.
This discovery represents a new frontier in battery science, combining quantum mechanics and practical engineering to create energy solutions that were once thought impossible. It highlights how quantum technology is moving from theoretical research into tangible, everyday applications that could reshape the way we live and interact with devices.

 Observation and Existence
The cartoon is funny, but it also cuts to the heart of what “existence” in physics really means:
Can there be particles that don’t interact with reality in any respect?
+ Short answer: No.
If a particle had no coupling at all — not electromagnetic, not weak, not strong, not gravitational, not even to the geometry of spacetime — it would be in principle undetectable. Physics could never include it, since no trace, signature, or effect could ever distinguish it from non-existence.
+ Closest examples we know:
• Neutrinos — couple only weakly and gravitationally.
• Gravitons (hypothetical) — interact only through gravity, making them effectively undetectable at human scales.
• Dark matter candidates — WIMPs, axions, etc., likely couple almost exclusively via gravity.
• Sterile neutrinos (hypothetical) — would avoid weak interactions, coupling only gravitationally.
All of these are extreme cases of minimal interaction — but not zero. Even gravity, however weak, leaves a principle-observable footprint.
+ Key principle:
In physics, to exist is to interact. Existence is not defined in isolation but through coupling — with fields, particles, spacetime, or observers. A particle that never interacted in any way could never enter an equation, leave a signature, or be inferred. Within physics, that is operationally identical to non-existence.
⸻
We experience the reality that interacts with us. This doesn’t mean that unobserved possibilities never “exist” in superposition; it means that our slice of reality is precisely the part that leaves a trace. Physics can only describe what is in principle connected — however faintly — to observation.

Sziasztok! Sikerült bizonyítanom a foton determinisztikus viselkedését, bármennyire is komolytalannak tűnik első hallásra. az alábbi megosztott oneDrive folderben találtok14 db text file-t foton szórási adatokról: [Raw shot files](https://1drv.ms/.../Ehev0HBbQm5FqDSykG9vWEYBny0fgEQZO6jFl...)
ezek éles laboratóriumi adatok erről a webhelyről: [https://ethz.ch/en.html](https://ethz.ch/en.html...) és ez az adatforrás linkje: https://ethz.ch/.../Datasets/Dataset_Public%20repository.zip szóval ha letöltitek bármelyik txt file-t, akkor nyissátok meg a photon_td_test.py nevü kódot, másoljátok ki, nyissatok egy google colab ablakot -> új munkafüzet ->másoljátok be a kód szerkesztőbe, és nyomjátok meg a play gombot bal oldalon felül. a futáskor aktív lesz a fájlok kiválasztása gomb, válasszátok ki a letöltött file-t, és le is fut a kód. valami ilyesmit kaptok majd, csatoltam a képet. A képlet alapból determinisztikus viselkedést vár a fotontól, és tökéletesen illeszkedik is, mint látjátok. Ismétlem, éles adatok, bármikor futtatható bárki által, a 14 fent lévő txt-nél mind a 14 esetben sokkal jobb illesztést kapunk, mint a quantum fizika fő atyaistene a Born szabály. Ha bővebben szeretnétek tudni, hogy is lehetséges ez, akkor íme a publikációm: https://zenodo.org/records/16781047 Bármennyire képtelenségnek tűnik, működik. Minden esetben. Ez csak akkor lehetséges, ha a valóság más, mint a Born szabály jóslata. Nagyon szeretném, ha egy szakember kipróbálná, és akár megmondaná, hogy miért nem jó, mit hibáztam, mit nem vettem számításba. Vagy persze azt, hogy ez így jó, és neki is ez jött ki.  köszi előre is!

 The closer we look at reality, the more it melts away beneath our fingertips. Matter isn’t solid at all deep down, everything dissolves into pure energy, endlessly vibrating.
Zoom in on an atom and you won’t find hard, tiny balls. Instead, you’ll see vast spaces, shimmering with charged fields, and the ghostly presence of particles that are really just ripples in an invisible sea.
In the world of quantum mechanics, electrons don’t orbit like planets and protons aren’t miniature marbles. They’re disturbances in underlying fields pulses of energy appearing and disappearing with every tick of time. Even what we call “mass” is an illusion, a brief moment where energy gathers and dances, creating the structure of the world as we experience it.
It’s as if the universe is an endless symphony, with everything from your skin to the farthest stars woven from resonating patterns of energy. Nothing is ever truly still. The deeper we go, the more reality looks like music: a projection of invisible rules, an ocean of motion shaped by quantum laws not by solid bricks.
This astonishing perspective, revealed by quantum mechanics and quantum field theory, flips our entire view of the cosmos. We are not built from particles, but from the patterns of energy waves in an endless, silent dance.

 Spacetime might emerge from many small world-like entangled systems, stacked in a way that their internal "languages" combine into a global geometry.
MERA is a type of tensor network — a way of representing complex quantum states using a network of simpler, local components (tensors). It was introduced by Guifrè Vidal around 2007 to efficiently simulate entangled systems.
But here's the shocker:
In holographic theories (like AdS/CFT), MERA looks like a slice of spacetime geometry itself.

 Time could be far more complex than we ever imagined.
A new theory by Dr. Gunther Kletetschka of the University of Alaska Fairbanks argues that time doesn’t move along a single line; it unfolds in three dimensions, just like space. In this view, space isn’t fundamental at all. Instead, it’s a byproduct of multi-dimensional time – the “paint” on a canvas made of time itself.
Kletetschka’s theory proposes six total dimensions: three of time and three of space. And unlike earlier ideas about 3D time, this one claims to offer experimentally testable predictions – including accurate calculations of particle masses like electrons, muons, and quarks. That’s huge, because explaining particle mass is one of the biggest unsolved puzzles in modern physics.
The theory could help bridge the gap between Einstein’s general relativity (which describes gravity and the large-scale structure of the Universe) and quantum mechanics (which governs particles at the smallest scales). These two pillars of physics have long been incompatible.
If correct, this framework could be a serious step toward a long-sought “Theory of Everything” – a unified explanation of all forces and particles in the universe.
Dr. Kletetschka describes time as a 3D fabric where:
◾ The first dimension is the forward motion we experience.
◾ The second allows for alternate versions of the same moment (imagine different outcomes of the same day).
◾ The third governs transitions between those alternatives – possibly unlocking movement across different timelines.
And unlike some past theories where causality breaks down, this one preserves cause and effect, even in a complex time structure.

 A Unified Theory in Sight?
Can this little mechanical model – built from a simple tetrahedral lattice – provide a new approach to unifying quantum mechanics, relativity, and thermodynamics?
In our latest OSF article (DOI: 10.17605/OSF.IO/NRAV5), we explore the Methane Metauniverse Model (MMU):
A geometric framework where the universe is described as a vibrating network of elastic nodes.
The axes (w1–w4) encode time, energy, spin, and mass.
Fundamental constants such as h, α, and G emerge naturally from the lattice structure.
Even entropy and superconductivity find a place in this model.
Could such a mechanical picture of space-time explain the deep harmony behind physics?
Take a look at the article and join the discussion!

 Many physicists and computer scientists, from John Wheeler to Google Deepmind's Demis Hassabis, have argued that reality is fundamentally made of information.
Wheeler called this "it from bit". But this is mistaken, argues Boston University physicist and philosopher of science, Gregg Jaeger.
“Wheeler supported Bohr’s view of quantum events and later summarized it with the statement “No elementary phenomenon is a phenomenon until it is an observed phenomenon’,” writes Jaeger.
Information supposes a relation between the information itself and its physical encoding.
Reality cannot be made of information, because without already existing physical objects to encode it, information does not exist.

James Joule played the major role in establishing the conservation of energy, or the first law of thermodynamics, as a universal, all-pervasive principle of physics. He was an experimentalist par excellence and his place in the development of thermodynamics is unarguable. Joule's life and scientific work culminated in the paper ‘On the mechanical equivalent of heat’, where he presented his detailed measurements of the mechanical equivalent of heat using his famous paddle-wheel apparatus. Joule's paddle-wheel experiment is the most famous of his conservation-of-energy experiments because, as we now know, it gave the most accurate results for the mechanical equivalent of heat.
 To mark the 360th anniversary of the Philosophical Transactions, we're spotlighting landmark papers.

 Ludwig Boltzmann was a visionary in a world that wasn't ready for him. In the bustling intellectual climate of late 19th-century Europe, while many scientists grappled with the tangible, Boltzmann dared to explore the unseen. He introduced the groundbreaking idea that atoms—too small to be seen even with the most powerful microscopes of his time—were the fundamental building blocks of nature.
With meticulous mathematical formulas, he developed statistical mechanics, bridging the gap between the microscopic atom and the everyday phenomena of heat and pressure. His theories explained how random motions of particles could result in the predictable laws of thermodynamics.
However, Boltzmann's revolutionary ideas met stiff resistance from the scientific community. Leading figures like Ernst Mach scoffed at the notion of atoms, dismissing them as mere fantasies because they could not be observed directly. This skepticism was relentless, and it took a toll on Boltzmann. Despite his profound contributions to physics, he faced mockery and professional isolation.
Tragically, in 1906, while on a family vacation intended as a respite from his struggles, Boltzmann ended his own life. He died never seeing the vindication of his theories, which occurred just a few years later when the existence of atoms gained empirical support.
Today, Boltzmann's legacy endures in the formula S = k log W, etched on his tombstone—a testament to a man who ventured beyond the visible and changed the fabric of science forever.

 Three centuries after Newton framed reality in fixed laws and deterministic equations, science has reached a radically new frontier, argue biochemist and complex systems theorist Stuart Kauffman and computer scientist Andrea Roli.
The biosphere – life’s evolving web – is not a clockwork mechanism but a self-creating, unpredictable system.
Organisms constantly repurpose their worlds in ways that cannot, even in principle, be foreseen or captured in a mathematical framework.
“We begin to see that the vast world outside of Set Theory is in a Domain of No Laws,” argues Kauffman and Roli.
Science must now confront a bold idea: reality is not fully governed by any law – and biology, not physics, holds the key to its deeper mysteries.

 In a groundbreaking experiment, Harvard physicist Dr. Lene Hau achieved what was once thought impossible. In 1999, she slowed down light to just 17 meters per second using a state of matter called a Bose-Einstein condensate an extremely cold cloud of atoms. Then, in 2001, she went even further by completely stopping a light pulse, holding it still for a moment before releasing it again without any loss of information. Her work opened new doors in quantum physics, optical communications, and our understanding of the nature of light itself.

 Einstein’s dream of unifying the forces of nature may be within reach
For over a century, physicists have chased a single, elegant theory to unify the fundamental forces of nature — a dream that consumed Einstein until his final days.
Now, a team of researchers claims they may have done what Einstein couldn’t: unite gravity and electromagnetism under one geometric framework.
Instead of treating electric charge and magnetic fields as external phenomena, the new theory sees them as natural curvatures and compressions of spacetime itself — much like gravity in general relativity. Using a more general form of geometry first proposed by Hermann Weyl, the researchers derived new, nonlinear versions of Maxwell’s equations from first principles. Their work suggests that light and electromagnetic radiation are not separate forces, but ripples in the very fabric of spacetime.
One of the most striking implications? Electric charge is reimagined as a localized compression in spacetime, and the familiar force on a charged particle — the Lorentz force — emerges naturally from the motion of particles along curved paths, or geodesics.
To put it simply: in general relativity, gravity is caused by the bending of spacetime around mass. This new work extends that idea — proposing that electric and magnetic fields also arise from how spacetime bends and stretches. Rather than being separate ingredients in the universe, these forces might all be woven into the same geometric fabric. It’s a shift in perspective that could unify what we’ve long thought of as disconnected.
The model also predicts random fluctuations in the electromagnetic field at the Planck scale, potentially offering insight into quantum phenomena and even the mysterious Aharonov-Bohm effect — where particles are affected by electromagnetic potentials, even in regions with no measurable field.
It’s not yet the final theory of everything. But it may be the most geometrically complete description of electromagnetism ever proposed.
