Geometric flower beds and pools descending towards Vienna in warm afternoon light. Empire at Dusk: An Afternoon at the Belvedere Eight photographs from a clear autumn afternoon at Vienna’s Belvedere, 14 October 2026. View the photographs A rigid industrial pipeline with approval gates faces a continuous loop connecting product development with real-world use Why Europe Is Falling Behind: The Conflict Between Waterfall Institutions and DevOps Europe’s industrial success shaped institutions that prioritize planning, standards and approval. When technological competition depends on continuous deployment and real-world feedback, how does that institutional legacy constrain the capacity to iterate? Read article Cover for Mei Liu's Honor of Kings S44 season review Don't Throw a Lead; Don't Lose Heart When Behind Mei Liu's Honor of Kings S44 season review: how a five-player team developed a shared economic model, jungle invasions, lineups and late-game positioning, with a radar chart for every member. Read article Conceptual illustration of von Neumann, Feynman, and Grothendieck in settings of computation, physical experiment, and mathematical structure Three Forms of Peak Intelligence: von Neumann, Feynman, and Grothendieck Von Neumann organised vast spaces of information, Feynman made equations run as physical processes, and Grothendieck rebuilt the space in which a problem could be posed. Their differences reveal why intelligence has no single highest form. Read article A reader runs equations, curves, dynamic models and structures from different fields in his mind How My Mind Works I take in information at the scale of a page, turn physical and abstract phenomena into equations and dynamic models, and revise my understanding through prediction errors and structural parallels across fields. Read article A company accuses users of actions it cannot see beyond the wall of its own platform Boycotting Anthropic Is Everyone's Responsibility Anthropic can observe inputs to and outputs from Claude, but not what users do with those outputs after they leave its platform. The author challenges both its evidence for distillation and its assertion of illegality. Read article A line drawing of scientists studying fluid flow and its possible links to finance and nuclear fusion If the Navier-Stokes Equations Are Solved, What Might Change in Finance and Nuclear Fusion? The value of a mathematical breakthrough may lie in the methods it creates. From American options to plasma control, this essay considers where research on the Navier-Stokes equations might lead. Read article A corridor of time running from an old residential neighbourhood through a 1990s shop, a personal computer and a smartphone to artificial intelligence Four Decades in the Life of China’s Post-80s Generation From the lingering routines of the planned economy to industrialisation, the internet, mobile life and AI, China’s post-80s generation has lived through changes that elsewhere unfolded across several generations. Read article A cartoon sculpture installation and a wall of comics in a museum gallery How We Appreciate Art Art keeps changing its forms, yet the artist is always condensing reality, emotion, thought, inspiration and context into a key frame. Recognising this is a decisive beginning in the appreciation of art. Read article A table and empty chairs left behind after a late-night conversation Not Long Ago In memory of Chinese rock musician He Yong. An original song about unfinished questions, a table left at dawn, and the years that quietly passed. In a black, yellow and orange comic illustration, a thinker tears open a speech balloon saying I understand in Chinese, revealing intricate geometric structures behind it Metaphorical Thinking: You May Only Think You Understand Metaphors can help you begin to understand. Depend on them, and the feeling of understanding can keep your thinking shallow and obstruct the development of abstraction. Read article An empty rain-wet street at blue hour, with streetlights and the brightening sky reflected on the pavement Blue Hour Before dawn, the streetlights still glow and the world holds its breath. Blue Hour is a psychedelic electronic rock song that travels from deep-blue stillness into the return of sunlight and ordinary life. Play the original MV Sunlight falls across an open book on a desk, where colored lines connect geometric and botanical sketches with a molecular model and a second notebook A Truth Model for Large Language Models: A Conjecture on Cross-Domain Abstraction Could connections across fields help large language models reach deeper abstraction? A conjecture informed by self-observation explores the difference between approaching a hypothetical truth core and building internal coherence. Read article The Chinese title Remembering He Yong on a deep brown background Remembering He Yong Remembering He Yong is also a way of remembering the force we are losing: a reflection on the Hung Hom stage, changing times, and the fullness and urgency of the desire to express ourselves. Read article Layers of ink and paper condense into a narrow gold lattice before opening into a structured field Could Classical Chinese Be a Better Way to Compress LLM Context? A small token-counting experiment suggests that Classical Chinese may offer a useful reference for compact, readable context inside large language models. This is a conjecture, not a scientific conclusion. Read article Five silver and gold trajectories converge at a cinnabar centre before forming one stable team structure What a Five-Stack Should Actually Practise: From Raising Individual Ceilings to Converting Team Strength For experienced five-stack players, further individual practice often yields very little. A mathematical model of theoretical ability, execution, cooperation and stability shows why training time is better spent converting strength the team already has. Read article Counting objects and arithmetic marks on dark paper dissolve into variables, geometry, and an abstract network of relations Why People Struggle to Learn Mathematics Many students learn mathematical metaphors and cover a large bank of problem types without ever building an abstract layer of definitions, relations, and transferable reasoning. Read article Dense ink glyph forms dissolve into an open field of neutral variables, operators, and relational geometry Why Pure Chinese Struggles to Enter the Abstract Layer of Modern Science Chinese can transmit scientific results, but it struggles to provide the semantically neutral containers that modern science needs to create new abstractions, formal languages, and theoretical tools. Read article Hardware, software platforms and intelligent systems form a layered computing topology along antique-gold paths on deep black paper The Computer Knowledge Topology for the AI Era From hardware, operating systems and cloud infrastructure to large models, RAG, agents, harnesses, loops and graph engineering, this essay maps five distinct knowledge domains and the capabilities each one requires. Read article Several hard-edged geometric pipelines converge on a cinnabar control desk as one person coordinates the parallel work When Thinking Becomes a Multi-Pipeline Process: More Thoughts on Agentic AI Agentic AI turns intellectual work from deep work in one pipeline into many pipelines moving at once. It amplifies human ability, but it can also drain the thinking process and make breadth look like depth. Read article Mathematical notes, a five-player tactical diagram, family images and development notes connect in antique gold across a dark workbench I Spent August Immersed in Agent AI A month of intensive Agent AI use connected my research in partial differential equations, game modelling, algorithm experiments, personal software and family archive work into one growing personal system. Read article Five blue-side heroes form one coordinated unit through a golden pentagonal network as five red-side opponents line up across an Honor of Kings-style battlefield Once Five Players Queue Together, the System Is No Longer Calculating Five Individuals When a five-stack enters matchmaking, the system must estimate more than five hidden ratings. It must price individual ability, team synergy, composition fit and network value. This essay explains a plausible online model for fast five-stack matchmaking and shows how a fixed team can organise drafts, shot-calling and stopping rules. Read article One blue-side hero stands in the foreground of a ten-player Honor of Kings-style match as nine strangers are linked uncertainly into two teams When You Queue Solo, What Is the System Actually Arranging? In a profit-first matchmaking system, a solo player is one node in a ten-player optimisation. This essay uses Bayesian updating, EOMM and combinatorial optimisation to explain solo queue, then offers practical ways to control hero choice, match risk, play time and spending. Read article Two teams confront each other across a five-on-five arena while player profiles and probability curves reveal the allocation logic of matchmaking Who Is the System Optimizing? Under a profit-first assumption, TrueSkill, EOMM, PCA, GNNs, survival analysis, and match optimization can be recombined into a commercial Bayesian machine that learns players, predicts value, and allocates experiences. Read article A riderless black horse on a frost-covered ancient road beneath cold moonlight The Lone Horse A Chinese-style R&B song inspired by Li Bai’s ‘Seeing Off a Friend’: a pavilion, a setting sun, a broken willow, and a lone horse become a farewell with no road back. Play the original MV Two offset translucent language structures connect through a silver sound wave and an unfolding path in a deep black space Learning a Language Is Not Putting New Subtitles on the World Two languages are not tables whose entries line up one by one. Translation can build a bridge and grammar can calibrate, but real learning connects sound directly to scenes and actions. Fluency forms first; accuracy then gradually converges. Read article A black mechanical paper-feed device produces neat blank sheets while an open notebook beside it holds a single unfinished stroke The Loss of Intelligence, Part II: When AI Answers for Us, Who Is Still Forming Judgement? AI can make the combined system more capable without making the user stronger. This essay examines how answers can end curiosity too early, and how metacognition, multidimensional databases and timeline thinking can protect cognitive sovereignty. Read article A continuous folded paper strip held by a cinnabar clip, surrounded by scattered scraps of paper The Loss of Intelligence, Part I: Why Does Thinking Get Harder as Information Grows? Short video does not simply make people less intelligent, but it may cut sustained thought into fragments that must constantly restart. This essay uses attention switching, dopamine, cognitive peaks and intellectual capital to explain the change. Read article Translucent structures in ice blue and violet-red draw close again before a hairline opening of light in a black architectural space Every Longing Must Meet Again Beginning with the Poincaré recurrence theorem, this essay proves why a finite measure-preserving system returns infinitely often, then turns ‘every longing must meet again’ into a romantic proposition that still respects the boundaries of the mathematics. Read article A thick paper volume bound with cinnabar thread lies beneath a black paperweight on a wooden desk while loose pages scatter in the wind The Loss of Intelligence Starting from intellectual power, decaying cognitive peaks and the dissipation of intellectual capital, this essay examines how short video fragments thought, how AI flattens the process of thinking, and how metacognition, multidimensional databases and timeline thinking can protect cognitive sovereignty. Read article A closed lotus bud waits for dawn above the ink-dark water of a Jiangnan pond on a rainy night The Lotus Blooms Late A female folk song born from four lines about youth passing and the hundred days pressing on. Over acoustic guitar and a restrained reggae pulse, a late-blooming lotus waits through spring, and for someone who never looks back. Play the original MV Local work subgraphs pass through independent review and evidence checks before converging layer by layer beneath a cinnabar human authorisation gate From Loops to Graphs: Building Convergent Intelligent Systems with Entropy Assessment and Human Authorisation Nodes From loop engineering to graph engineering: a formal account of dual AI Judges, module quotient graphs, information gain and human authorisation nodes in a cycle of entropy expansion, verification and evidence-based reduction. Read article Warm, transparent domes on a dark landscape connect through a golden network to a single control core in the distance Refuting Musk: Relative Wealth Is What Separates Rich from Poor Musk believes AI and robots will bring extreme abundance. But plentiful goods do not settle who owns the productive system, and comfort is not the same thing as equality or freedom. Read article A warm-white manuscript on a dark desk as a dense grey statistical pattern seeps into the paper fibres from the right Claude’s Watermark Is Contaminating Authors’ Copyright Claude embeds a hidden watermark in text in the name of compliance with the EU AI Act. Because that signal cannot distinguish proofreading from rewriting or full generation, it casts suspicion of machine authorship over work written by people. Read article Two lovers embrace by a window in the blue light of dawn as the city and the rainy night fade behind them Beside Me They are still beside me, yet I have already begun to miss them. An English blues jazz song about intimacy, distance and the coming dawn, with English and Chinese subtitles embedded in the original music video. Play the original MV A woman at a café window on a rainy night, facing overlapping views of Buenos Aires and Shanghai, with an unsent letter and a white handkerchief on the table Le parfum de ton absence A French song about absence, memory and a love left unfinished. In the bilingual music video, the French lyrics and a poetic Chinese rendering follow the music line by line. Play the MV with synced lyrics Two people sit together on a dusk coast, their nearly touching hands joined by a thin line of warm light Saudade: You Are Still Here, and I Already Miss You Saudade is the longing that can begin before loss: someone is still beside you, yet you already know the moment will one day become memory.

Read article A Transformer network crosses a glowing computational threshold and branches into probabilistic paths Will Transformers Become Bayesian Once Compute Crosses a Threshold? Bayesian adapters, attention and in-context inference may help Transformers represent uncertainty, update hypotheses and choose when to ask, search or wait. Read article A dark probabilistic landscape where scattered evidence converges into a warm path of updated belief Bayesian Probability and How to Live With Uncertainty Bayesian thinking begins with partial evidence, updates beliefs without turning every new signal into a verdict, and separates probability from action. Read article Three teenagers in blue-and-white school uniforms walk from an old campus towards a world opening in the distance I Finished My First Novel. It’s Called I Misjudged You I Misjudged You, a nine-part ensemble novel, will soon begin its serial run. The story starts at a Tianjin school in 1997, opens into a widening world, and repeatedly returns the act of judgement to the reader. Read article A harbor in the blue hour after rain, with water washing over the shore and an empty bench facing warm lights in the distance Harbor The finished version of Harbor: night wind, tides and longing carried by acoustic guitar and a percussive rhythm, with word-level lyrics synced to the original recording. Play with synced lyrics A warm gold path crosses a branching map of future states on dark textured paper What the Bellman Equation Can Teach Us About Life The Bellman equation offers a way to think about life as a sequence of decisions: weigh today's reward, the next state and the options that remain. Read article Two entropy trajectories diverge across dark paper, one breaking into fragments while the other forms a resilient structure that preserves difference A New Definition of Right and Wrong Through Entropy A decision is right when it reduces avoidable uncertainty, mismatch, irreversible harm and displaced disorder relative to the path not taken. Read article A silver engineering loop with two judging nodes and a red human checkpoint on dark paper Loop Engineering: Where Autonomous Systems Must Stop A practical architecture that separates goals, execution, judgment and human authorization so autonomous AI systems know when they must stop. Read article A four-stage visualization of Chinese calligraphy moving from topology to geometry, ink texture and brush dynamics I dreamed of homeomorphic manifolds, then used them to analyze calligraphy A dream about homeomorphic manifolds became a working model of Chinese calligraphy built from topology, geometry, finite-scale ink and brush dynamics. Read article Silver and gold information flows cross a dark layered network, forming local pulses and focal points How Stiffness Constraints and Information Entropy Can Work Against Deep Learning, with Further Implications: An Interactive Illustration Starting from the FE-E experiment, an interactive timeline and switchable metrics reveal how stiffness, mass and information-entropy constraints can work against learning, before extending the findings into a framework for observation and educational intervention. Open the interactive explainer Silver and gold information flows crossing a dark layered neural network with local pulses and concentration When stiffness and entropy constraints backfire in deep learning An FE-E experiment found smoother gradients and steeper loss slopes without earlier learning, suggesting that stiffness and entropy may work better as observers than controllers. Read article Game footage and landscape-format lyrics from the dark gothic death metal video Wujing Wujing Wujing, a dark gothic death metal video with landscape-format lyrics. Watch video An empty chair stands in a shaft of window light inside a black-and-white room I Can’t Hear Clearly You are so close to me, and still so far away. The window stays open, autumn passes through, and silence remains between two people. Read and listen Amber and cyan particles move on either side of a glowing entropy wall on a dark interactive page Breaking the Entropy Wall: Brains, AI and Gödel Incompleteness Information entropy and neural-network bottlenecks reveal why a closed system with finite parameters must contain blind spots it cannot compress or learn. Move the entropy slider, watch particles strike the wall, and compare a closed AI with an open brain that continues to absorb feedback. Read article The Yoneda lemma, a formula and gold relational nodes on a dark background The Yoneda Lemma: Everything Is Relation To know an object is to know the sum of its relations with everything else: an interactive philosophical note grounded in category theory.
