In General Relativity and Quantum Gravity, diffeomorphism often called... diffeomorphism invariance or general covariance is an isomorphism of differentiable manifolds that defines the physical nature of spacetime. Rather than a mathematical tool, diffeomorphism is a smooth, bijective (invertible) mapping between two open sets where both the function and its inverse are continuously differentiable, ensuring that not only are the spaces homeomorphic (topologically equivalent), but they also share the same basic regarding calculus/differentiation. Diffeomorphism ensures that the equations of physics are independent of the coordinate system used, preserving the fluid structure of warped or deformed shapes without tearing, ripping, or creating holes. 🔗show more

Jensen's inequality gives the difference between the average value... of a convex function φ, and its value at the center, where both “average” and “center” are defined in terms of some distribution p_X. When the function φ is flat, or the distribution is narrow, they agree.show more

New Subquantum Informational Mechanics framework (NMSI). A radical mathematical... shift in fundamental physics is introduced in the NMSI, inferring that information rather than energy or matter is the fundamental substrate of reality. The Universe isn’t expanding and doesn’t die thermally, the vacuum is not empty, but is an active medium composed of elementary units of information called infobits which self-organize through progressive compaction onto dynamically viable structures. The cosmic evolution is governed by optimal informational transport modeled upon a substrate called the Riemann Oscillatory Network (RON). The radical concept treats physical fields such as EM & gravity as emergent properties of a Coherent Logical Oscillator influenced by the Riemann zeta function (ζ) that governs the organization of space, time and mass. 🔗show more

Trans-identified males are obsessed with the notion that they... will be raped or abused if they use male spaces. The reason for this obsession is that, more often than not, they are using porn that depicts women being bound and / or assaulted (or men 'forcibly' transformed into women by way of sexual abuse), which they find sexually thrilling. It is a masochistic humiliation fetish. Such men see being a woman as something humiliating. (And by the time they begin "identifying" as a little girl, they've already consumed a substantial amount of BDSM content.) When these concepts are repeated in the media, the result is not only to validate the fetish, but also to humiliate women, by proxy, for the pleasure of men with this fetish.show more

In classical differential geometry the Ricci curvature is a... unit of measure that defines the curvature of a manifold at a given point. It is expressed as the contraction of the Riemann tensor which equates the progressive curvature of a manifold. The Ricci curvature is essential in the study of Einstein field equations which relates the curvature of spacetime to the mass and its energy density. When studying #quantum field theory in curved spacetime, the Ricci curvature plays a vital role in the equations of motion for particles and fields, it’s specifically used to measure the curvature of the Fermi surface, which is a starting condition of electronic properties in the Hilbert space.show more

🚨 AN OXFORD PHYSICIST JUST CLAIMED QUANTUM PHYSICS MAY... BE BUILT ON A MATHEMATICAL ILLUSION. And if he’s right, quantum computers could hit a hard limit around 400 qubits. Tim Palmer argues that modern quantum mechanics relies too heavily on irrational numbers and the infinite mathematical continuum structures that may not actually exist in physical reality. Instead, he proposes a new framework called “Rational Quantum Mechanics” (RaQM). The core idea: Nature may not be continuous at all. Reality could be built from discrete, rational relationships rather than infinitely precise mathematical values. Why this matters: According to Palmer, many of quantum physics’ strangest mysteries Schrödinger’s cat, spooky action at a distance, infinite superpositions, and other paradoxes might not be real physical phenomena. They could simply be artifacts created by the mathematics we’re using. The biggest practical prediction? Quantum computers may eventually stop scaling, not because of engineering problems, but because nature itself refuses infinite quantum precision. The deeper implication is one of the biggest shifts in physics since Einstein: What if the “weirdness” of quantum mechanics was never nature… but the mathematics we projected onto it? What happens when the universe turns out to be fundamentally finite, discrete, and geometric underneath the equations?show more

As a gynecologist, one of the most frequently asked... questions is about the ''hymen''. The hymen is not a structure located deep inside the vagina. It is a thin, flexible fold of tissue situated very close to the vaginal opening, anatomically at the entrance of the vaginal canal. It is typically found about 1–2 cm inside the vaginal opening, but in many women, it is almost at the surface. Therefore, the common belief that it is located deep inside is incorrect. One of the most important points is this: The hymen is not a closed membrane. It naturally has openings that allow menstrual blood to pass. Additionally, the structure of the hymen varies from person to person. Its thickness, elasticity, and shape are not standard. In some women, it may be very thin and elastic, while in others, it may be minimal or barely noticeable. This is completely a normal anatomical variation. A common misconception is that changes in the hymen occur only due to sexual intercourse. In reality, factors such as certain physical activities or tampon use can also lead to stretching or changes in this tissue. Therefore, the hymen is not a reliable indicator of a person’s sexual history or “virginity.” In summary, the hymen is a small and variable anatomical structure. The meanings attributed to it are largely shaped by sociocultural beliefs rather than medical facts.show more

QUOTE 1: A worldview without feelings is a cold... structure; feelings without a worldview are a blind force. : The author offers a precise and balanced insight into the relationship between intellect and emotion. A worldview without feelings becomes a cold, lifeless structure rational but empty, capable of logic yet devoid of warmth or motivation. Conversely, feelings without a coherent worldview become a blind force powerful but directionless, easily manipulated or destructive. True human maturity requires the harmonious union of both. The mind provides clarity, structure, and long-term vision. Feelings supply energy, empathy, and moral intuition. When integrated, they create a living philosophy: thought that is compassionate and emotion that is wise. This synthesis is the foundation of a complete human being. Without it, we risk becoming either heartless calculators or passionate but reckless actors. The highest expressions of humanity justice, creativity, love, and wisdom arise only when reason and feeling work together as equal partners. QUOTE 2: The unity of humanity is not a dream but a necessity: it is the only path to universal security. : The author asserts that the unity of humanity is not an idealistic dream but a fundamental necessity. In an interconnected world facing global threats climate change, pandemics, nuclear risks, resource scarcity, and technological disruption fragmented efforts and national rivalries are no longer sustainable. True universal security cannot be achieved through dominance, isolation, or temporary alliances. It requires a higher level of human solidarity: shared institutions, mutual trust, collective responsibility, and a common commitment to the survival and flourishing of our species. Without unity, every nation remains vulnerable, no matter how powerful. Unity does not mean erasing diversity or sovereignty. It means building a framework in which differences are respected while common survival imperatives are placed above them. It is the recognition that in the 21st century and beyond, humanity’s fate is collective. The path to lasting security runs through unity. Anything less is merely managed risk.show more

Notice how the Alhambra's external facades are plain and... simple, while the inside is most dazzling in splendour and beauty. This is a feature of the Islamic ethos. It draws from the same notions of modesty that emphasize beauty of character and public humility. The ethos that would translates into the veil, or the Sufi's simple external appearance - while he carries a glimmering ocean within. An ethos also conveyed by St Peter when he wrote: "When adorning yourselves, let it not be that outward adorning of plaiting the hair, and of wearing gold, or of putting on apparel; but let it be the hidden man of the heart which is not corruptible, even the ornament of a meek and quiet spirit, which in the sight of God is of great price."show more

I think a big mistake is believing that if... something is here, we should be able to see it. Right? The lights in the sky and the pilots or the gods or whatever they are? I think we assume out of arrogance and ego. An insect can crawl across your hand and never understand that you are a whole entire being. It only experiences pressure, heat, vibration, and movement. A fingertip appears. A shadow passes. The insect never sees the body attached to it. The insect does not have access to the full image. Ever. I think our situation may be exactly the same. Whatever people call the phenomenon, nonhuman intelligence, gods, or something else entirely, may be present in full while we only register a portion of it. We notice effects, not the actual being. Changes in perception. Anomalies. We expect a face when all we are capable of sensing is the fingertip. Let me explain. Reports are always partial and strange. Lights, shapes, impressions, symbols, missing time, pressure, fear, calm. None of it ever shows us a full being, or the real craft; because our senses are not built to assemble it. Just like the ant cannot assemble a human from a few sensations. Now that doesn't mean what we are seeing is fake. It means the insect’s world is smaller than the thing interacting with it. I get sick of people saying there is no there there, I think they are making the same mistake the insect would make. Our reality is likely a thin slice of what actually exists. We move through a world full of forces and intelligences that exceed our resolution. We are not seeing nothing. We are seeing effects. And effects are often the only honest proof a limited observer ever gets.show more
