Wave 15 is wrapped up. Three posts shipped across November and December 2028, covering quantum information theory, classical electromagnetism, and the physics of Earth’s climate system. Alongside the content, this devlog covers a set of platform improvements that have been in progress since Wave 14: a search UX overhaul, a simulation glossary, structured data (JSON-LD) across all pages, and a visual refresh of the categories taxonomy.
Three posts, three of the most foundational topics in physics, each carefully linked to simulations already on the platform:
Qubits and the Bloch sphere, quantum entanglement and Bell inequalities (CHSH bound 2√2), BB84 quantum key distribution and its information-theoretic security proof, universal quantum gate sets, Grover’s O(√N) search, and Shor’s polynomial-time factoring. Six sections, four linked simulations. Published Nov 4, 2028.
All four Maxwell equations (differential and integral), electromagnetic wave propagation and Poynting vector, Faraday induction and Lenz’s law, Hertzian dipole radiation and antenna parameters, skin depth in conductors, and transmission-line theory with SWR and the Smith chart. Six sections, four linked simulations. Published Nov 18, 2028.
Energy-balance model and greenhouse forcing, climate feedback decomposition (Planck, water vapour, ice-albedo, lapse rate, cloud), global carbon cycle fluxes and ocean acidification, tipping element thresholds, atmospheric circulation cells and Hadley-cell expansion, and the CMIP6 model hierarchy. Six sections, four linked simulations. Published Dec 2, 2028.
Wave 15 brings the blog to 96 posts across five series: Devlog, Spotlight, Learning, Tips, and Announcements. The Spotlight and Learning series together account for 56 posts (58%) and are the primary organic search entry points for new visitors.
The platform’s third anniversary falls in 2028. Three years in, the coverage has grown from a handful of physics simulations to 345 interactive demos spanning physics, chemistry, biology, mathematics, economics, computer science, and Earth sciences. Wave 16 planning starts now.
Spotlight #30 required extra care to distinguish quantum information theory (what quantum systems can communicate) from quantum computation (what quantum computers can compute efficiently). The Holevo bound — you can only extract 1 classical bit from a qubit — is routinely misunderstood as a limit on quantum computation power, when in fact it is a statement about communication. Getting the Shor section to explain why reducing factoring to period-finding helps, and why the QFT makes period-finding fast, without requiring knowledge of the quantum circuit model from the reader, took several rounds of revision.
Learning #25 structures the Maxwell equations narrative around the one term Maxwell himself added: the displacement current ε_0 ∂E/∂t. Without it, charge conservation is violated in Ampère’s law for time-varying fields. With it, the equations become self-consistent and predict waves. That single addition — made on theoretical grounds with no experimental evidence at the time — predicted the speed of light and unified optics with electromagnetism. The skin-depth and transmission-line sections were added specifically for readers with RF or PCB engineering backgrounds; these topics appear repeatedly in reader feedback but rarely in physics-focused blogs.
Spotlight #31 was the most editorially challenging post of Wave 15. Climate science sits at the intersection of physics, ecology, economics, and policy; the target was to present the quantitative physics (radiative forcing formula, feedback decomposition, carbon cycle fluxes, tipping thresholds) without editorialising the policy implications. The tipping elements section uses published threshold ranges from McKay et al. (2022) and IPCC AR6; every number is sourced. Describing the Hadley-cell expansion and its connection to subtropical drying required working through the thermal-wind balance carefully.
Alongside content, Wave 15 included the most significant set of platform improvements since the PWA offline-first update in Wave 4. Four changes shipped:
Instant search now shows a preview snippet alongside the simulation
title. Keyboard navigation (arrow keys + Enter) added. Search
history persisted to localStorage with a 30-item limit. Query
parameter now round-trips via URL (?q=lorenz) for
sharing and browser-back navigation.
New page at /glossary/: 150+ terms linked across all
simulation pages. Each term has a one-sentence definition, a
mathematical formula where appropriate, and links to simulations and
blog posts that use it. Built as a static HTML page with anchor IDs;
zero JavaScript required.
All 345 simulation pages now include
SoftwareApplication schema, all blog posts include
BlogPosting + BreadcrumbList, and category
pages include CollectionPage. Validation passes in
Google’s Rich Results Test. Estimated impact on impressions:
+20% SEO visibility for schema-eligible search features.
The /categories/ index now groups 75 categories into 10
domain sections (Physics, Chemistry, Biology, Mathematics, Computer
Science, Earth Sciences, Engineering, Economy & Society,
Medicine, and Arts). Each domain shows simulation count and a visual
accent strip. Mobile grid improved from 1-col to 2-col at 480 px.
The service worker was updated to v15 to invalidate old
caches for the new glossary page and updated category index. The
stale-while-revalidate strategy for simulation assets remains unchanged.
No breaking changes for offline users.
sitemap.xml was extended with Wave 15 blog posts and the
new /glossary/ page. The sitemap now contains 445+ entries.
All URLs use canonical https://www.mysimulator.uk/ origin
to match the canonical tags added in Wave 13.
Wave 16 themes are drafted. Three candidates emerged from unfinished items in the full-spectrum plan and reader requests:
Hertzsprung-Russell diagram, stellar structure equations, nuclear burning stages, supernova mechanisms, neutron star equation of state, and gravitational-wave sources.
Reynolds decomposition, boundary layers, Kelvin-Helmholtz instability, the turbulent energy cascade, Kolmogorov microscales, and LES/DNS trade-offs.
DNA replication fidelity, protein folding energy landscape, ATP synthase rotary motor, cytoskeletal dynamics, and CRISPR-Cas9 guide RNA targeting.
A systematic a11y audit of all 345 simulations: ARIA labels, colour contrast, reduced-motion mode, keyboard controls, and WCAG 2.2 AA compliance.
Of these, the fluid dynamics and cell biology posts have the strongest simulation backing already in place: Navier-Stokes, SPH, LBM, Kelvin-Helmholtz, DNA replication, and CRISPR simulations are all live on the platform.
Fifteen waves in. The subjects covered now span essentially the entire breadth of undergraduate science. Wave 16 pushes into graduate-level territory: stellar structure, turbulence theory, and molecular cell biology. The interactive simulation format scales into this territory comfortably — the physics is more complex, but the core pedagogical model (visual + quantitative + interactive) remains the right approach.
The platform launched in late 2025 with fewer than 50 simulations and a
simple homepage grid. Three years later: 345 simulations, 75 categories,
96 blog posts, 15 content waves, a full PWA with offline support,
Ukrainian localisation, and a blog series system that has produced 56
deep-dive educational posts. The simulations that received the most
external links this year were
double-pendulum, carnot-cycle,
navier-stokes, and lorentz-attractor —
none of them recent additions; the classics keep finding new audiences.
If you have a simulation or topic request, the contact page is always open. Wave 16 target: spring 2029.
