nuclear physics

Go beneath C# and .NET—from CPU, kernel, processes and threads to IL, JIT, native code, stacks, heaps and GC. Build the runtime mental model you need before deciding where, why, and whether a system should be distributed.

Microservices aren't built with boxes on a diagram—they're built with owned truth, stable contracts, idempotent messages, and controlled failure.

The Angular companion to NEXUS-1: From File to Framework ports a 5,900-line single-file operator console into a real application, screen by screen, auditing every claim it makes along the way.

From Flow to Proof turns distributed-system promises into explicit models, properties, counterexamples, and evidence. Explore state machines, contracts, temporal logic, concurrency, ownership, refinement, and honest proof boundaries—with companion artifacts at github.com/gregory82gr/Nexus-1-phase-0.

From Queue to Core reveals the stochastic foundation behind reactor kinetics: birth–death chains, master equations, delayed neutrons, feedback, deterministic point kinetics, and C# algorithms — all explained through the NEXUS-1 demonstrator with clear boundaries and interpretable results.

When a control loop must learn instead of obeying hand-written rules, how do you trust what it decides? From Trial to Policy shows you how to build an interpretable reinforcement-learning agent from first principles, where every decision lives in a readable Q-table rather than a black box. Every concept is wired to a live, zero-install NEXUS-1 console in your browser, so you don't just read about reinforcement learning — you watch it learn, inspect every choice, and understand exactly why the policy recommends what it does.

When something trips and two hundred alarms fire at once, which one is the cause? From Flood to Cause shows you how to build deterministic, grounded, auditable root-cause analysis where a causal engine decides and a language model only explains — never diagnoses, never guesses, and abstains the moment grounding is absent. Every concept is wired to a live, zero-install NEXUS-1 console in your browser, so you don't just read the architecture — you drive it.

Stop reading dry atomic physics textbooks and start driving a live nuclear reactor from your browser. From Grid to Core takes a reverse-engineering approach designed for software, control, and electrical engineers, walking you upstream from the familiar 400 kV switchyard straight into the nuclear core.
