Lemeit links to Eureka, Aire Escolar and teaching materials, with secondary links to the Physics concept map, weather and water quality. Its original hand-drawn SVG sensor, light bulb and notebook use cream #FAF7F2, oxide orange #9B3D00 and teal #009688. The personal calligraphic L belongs to Luciano Lamaita, not the Lemeit umbrella brand.
Encuentro: the Lemeit symbol¶
The visual language comes from Feynman diagrams: lines, arrows and an interaction vertex. In physics these diagrams represent contributions to interaction calculations, not photographs or literal particle trajectories. Straight lines with arrows are used for fermions; wavy lines can denote photons and certain other bosons. Educational reference: ATLAS/CERN, Feynman Diagrams.
For Lemeit, this structure is a metaphor for ideas meeting. It is not assigned a particular reaction or physical process. The vertex connects science, education and the environment as a brand image, rather than an experimental claim.
| Design element | Brand interpretation |
|---|---|
| Straight segments and arrows | Paths arriving at and continuing from an encounter |
| Orange vertex | A meeting point for questions, people and projects |
| Teal wave | A connection opening a new possibility |
| Thin, simple geometry | Favicon legibility and consistency with the portal drawings |
Palette and construction¶
Cream #FAF7F2 is the background; oxide orange #9B3D00 marks the segments, arrows and vertex; teal #009688 marks the wave. This original SVG uses vector geometry, without font dependencies. Automatically oriented arrowheads are enlarged relative to the line width. Open or download Encuentro SVG.
Interacción: retained alternative¶
Its two vertices are connected by a wave, and its arrows were also corrected and enlarged. It remains backed up and does not replace Encuentro as the selected favicon. Open or download Interacción SVG.
The calligraphic L identifies Luciano Lamaita personally and represents Profe Lamaita, not the Lemeit brand. Teaching portal documentation.
Eureka: final composition¶
The introduction retains EUREKA with AI in superscript and “ancora imparo — aún aprendo”. Four fixed areas surround the central explanation and tutor button: tesseract and mass–spring at left, Lorenz and pendulum at right. Each model moves within its own area; panels do not drift or rotate. Small screens show the introduction first, then a two-column model grid.
A pause control stops the motion. Reduced-motion preferences are respected, and evolution stops while the tab is hidden. Small equations, orange markers, trails and state readings accompany each model, without a calculation table or scene selectors.
These are illustrative mathematical models, not measured data: projected 4D hypercube rotations; Lorenz with σ=10, ρ=28, β=8/3 and RK4 integration; ideal frictionless mass–spring x=A cos(ωt); and the ideal nonlinear pendulum θ̈+(g/L)sinθ=0, integrated with RK4 without the small-angle approximation. Unverified scientist quotations were not restored.
Favicon and retained alternative¶
Encuentro is selected as the Lemeit favicon, at landing/favicon.svg. Thin orange segments meet a teal wave on cream. Arrowheads use automatically oriented SVG markers, enlarged relative to the line. The HTML declares a versioned icon URL to refresh caches.
Interacción remains in docs/identidad-lemeit/favicon-interaccion.svg in the private Eureka repository for future use. Its four arrows were corrected too. These are original brand symbols inspired by Feynman diagram notation; no specific physical process is assigned to them. Other project favicons remain unchanged.
Publishing and verification¶
Both Lemeit and Eureka use Git-connected Pages projects. Merging main triggers their deployments. Teaching materials are maintained independently in lemeit/aboutme. Environmental apps stay at https://app.lemeit.ar/aq/, /emas/ and /wq/; no environmental data, APIs or app logic changed.
JavaScript syntax, SVG parsing and links were checked, along with desktop scenes and icon previews at 16, 32 and 64 pixels. Exhaustive mobile visual review remains pending. Local 127.0.0.1 previews require a running local server; published Cloudflare sites do not.
Earlier floating and relocating panel experiments are not the final published layout.
Scroll-based project tour¶
The portal reads “Ciencias · Educación · Ambiente” and has no top navigation menu. The connected illustration acts as a visual index: sensor → Aire Escolar, light bulb → Eureka, notebook → teaching materials. Selecting a symbol scrolls to its chapter; the external site link appears in that chapter's short description.
Each chapter occupies at least one screen, revealing its enlarged drawing and description as the visitor scrolls. Scrolling remains native; only the scrollbar is visually hidden. IntersectionObserver drives the reveal in landing/lemeit-scroll.js, with readable content when JavaScript is unavailable or reduced motion is requested. Stable anchors are #aire-escolar, #eureka and #materiales. New chapters can extend this pattern.
