- EssayA Physical Theory of Information
Every bit is written in something physical, and physics charges exactly three prices for it: kT ln 2 of heat to let it go (Boltzmann's constant), h/4 of action to change it (Planck's constant), and 4 ln 2 Planck areas to hold it on a horizon (Newton's constant, with ħ and c). Read this way the constants of nature are the price tags of a bit, and Jacobson's 1995 derivation of Einstein's equations becomes the requirement that the heat price and the area price agree at every horizon; each claim is tagged as established, derived, synthesis or conjecture, and the one open question, whether a laboratory bit and a horizon bit are the same object, is stated with the experiments that bear on it.
- EssayPhysics, Bit First
Physics is still taught in the order it was discovered, so k, h, c and G arrive as four unrelated facts and information arrives last or not at all. This essay proposes a different spine: one rule (possibility is never lost), one object (the bit, located possibility), three prices set by k, h and G, c as the converter between them, Einstein's equations as the requirement that the heat and area prices agree at every horizon, and quantum gravity restated as a specification for the object that pays all three; nothing in the physics changes, only which facts are primitive.
- EssayThe Automation of Why
A first-principles case that the scarce resource in the information age is no longer the capacity to answer but the curiosity to ask—and that a question, measured in bits and joules, is the cheapest high-leverage act in physics. Argues for automating 'why' through Seeker, an environmental curiosity engine that generates, verifies, and compounds questions to close the epistemic gap in planetary stewardship.
- EssayEnvironmental Latency: Closing the Hundred-Billion-Fold Control Gap Between Ecological Disturbance and Human Response
Environmental latency—the summed delay across sense, transmit, understand, decide, and act—is the single physical variable that decides whether a feedback loop can regulate the biosphere at all. Unbounded for four billion years and measured in decades under twentieth-century regulation, it is now collapsing toward the seconds-scale floor set by transmission and actuation physics as foundation-model inference finally closes the loop.
- EssayPlanetary Dead Time: Overcoming the Hundred-Billion-Fold Control Gap in Environmental Stewardship
Every instance of environmental degradation runs a physical control loop—sense, transmit, understand, decide, act—historically hard-capped by the 39-bit-per-second limit of human language and the institutional friction it breeds, a structural delay named here Planetary Dead Time. The convergence of ubiquitous IoT sensing and machine-speed AI foundation-model inference has collapsed that bottleneck, letting environmental protection evolve from post-hoc forensic remediation into a real-time, planetary nervous system.
- BookBits Protect Its: A Children's Book
A picture book carrying the corpus's central thesis—Bits Protect Its—down to first principles a child can follow. It traces the hundred-year chain of discovery from Maxwell's demon through Shannon, Landauer, Bennett, and Wheeler to a single claim: knowing is cheaper than forcing, by law. And it introduces Jed's Angel, the planetary-scale defender that watches, thinks, and gently nudges the living world toward life.
- EssayWhy von Neumann Was Right
John von Neumann's 1948 instruction to Shannon—call your information measure entropy—was a statement of mathematical identity, not convenience: Boltzmann's thermodynamic entropy and Shannon's information entropy are the same function. This essay traces that identity through Jaynes, Maxwell's Demon, and the Landauer limit to a single number fixed by fundamental constants: at 298 K, erasing one bit costs about 0.0178 eV, while a single carbon–hydrogen bond holds roughly 240 times as much. The gap between the cost of knowing and the cost of moving matter is written into the electromagnetic structure of the universe.
- EssayArtificial Energy
Energy has been misnamed for two hundred years. Names three tiers—mass-destruction (combustion, fission, fusion), passive gradient harvesting (solar, wind, hydro), and the information-rich frontier it calls Artificial Energy: matter engineered to harvest free-energy gradients selectively, as the biosphere has for 3.5 billion years—and argues AE is the natural peer of Artificial Intelligence as a civilizational technology layer.
- EssayThe Bond-Bit Ratio
Information is at least 240 times cheaper than force, as a matter of physical law. This page derives the floor ratio between Landauer's bound at 300 K and the C–H bond enthalpy, fixes the constants, and exists to be cited.
- EssayEvery Question Is a Physical Act
Distills the formal argument of 'Observation IS Protection' into a short, accessible piece: a question is physical (it costs energy by Landauer, its answer extracts work by Sagawa–Ueda, it changes the state of an existing gate), and AI completes the circuit between observation and actuation that humans cannot close at planetary speed. Self-described as a summary of the longer paper.
- EssayThe Epistemic Boundary: Observation IS Protection
Derives—from Landauer's principle, Sagawa–Ueda mutual-information work extraction, and Bardos–Lebeau–Rauch boundary observability theory—the proposition that observation is not a precondition of environmental protection but is itself the protective act. Every catastrophic environmental event was preceded by physically encoded information that was never promoted to the epistemic boundary; the universe's spontaneous processes, given a question, configure themselves toward order.
- EssayThe Missing $Quadrillion
Identifies a second economic channel that every major AI-impact forecast (Goldman, McKinsey, PwC) has missed: the bond-bit asymmetry. Channel A asks what happens when AI substitutes for cognitive labor; Channel B asks what happens when information substitutes for physical manipulation across the entire material economy. The second channel is roughly twice the size of the first and reframes the path to a $1-quadrillion economy.
- EssayThe Intelligence Leverage Equation
Public-facing presentation of the Intelligence Leverage Equation Λ = Mc² / (I·k_BT·ln 2), which captures the bond-bit asymmetry as a single dimensionless quantity. Names 'Jed's Angel' as the practical realization of Maxwell's demon and reframes the environmental professional's role from boulder-pushing to designing the intelligence that keeps the boulders from rolling.
- EssayThe Thermodynamic Foundations of Entropic Shepherding
Derives the Intelligence Leverage Equation from first principles by synthesizing Landauer's bound, the Sagawa–Ueda generalized second law, bond-energy quantum constraints, boundary observability theory, and mass-energy equivalence. Proves the Bond-Bit Asymmetry—that information processing can substitute for physical intervention at leverage ratios of approximately 10²⁰ for typical environmental scenarios at room temperature—and grounds the asymptote of zero-cost stewardship in physics rather than economics.
- EssayThe Thermodynamics of Artificial Intelligence: A First-Principles Analysis of the Maxwellian Demon Hypothesis
Asks whether AI agents operating via feedback loops—RL agents, autonomous control systems—function as Maxwell's demons in a first-principles physical sense, and reconciles their internal computational thermodynamic costs with the work they extract from stochastic environments. Traverses the Sagawa–Ueda equality, SGD energetics, and recent experimental realizations of autonomous demons in solid-state and quantum systems.
