ATrain Slides — Grand Tour

ATrain Slides

A grand tour — text, math, tables, figures, diagrams, and rich sandboxed widgets

You author it by hand · Claude edits it live over MCP

SECTION 01

The canvas

A free-form 1920×1080 world of absolutely-positioned elements — the same primitives whether a human or an AI places them.

Shapes & primitives

Rich text & inline math

Mix bold, italic, and code with inline equations like $E = m c^{2}$ right in the sentence.

The diphoton invariant mass $m_{γ γ}$ peaks near $125 GeV$ , consistent with the Higgs boson. Press Alt+= to drop in an equation inline.

Fonts, sizes, and colours are per-run and can link to the theme, so a restyle sweeps the whole deck.

Equations

L = - \frac{1}{4} F_{μν} F^{μν} + \overset{ˉ}{ψ} (i γ^{μ} D_{μ} - m) ψ

i ℏ \frac{\partial}{\partial t} Ψ = \hat{H} Ψ

m_{γ γ} = 125.1 \pm 0.2 GeV

e^{iπ} + 1 = 0

SECTION 02

Designed with native elements

Cards, grids, timelines, quotes — built from real shapes, text and images. Every piece is yours to move and restyle.

The deck is the source of truth. You edit it by hand, Claude edits it over MCP — the same validated ops, the same live canvas.

SECTION 03

Data, plots & science

Figures as images, native bar charts, and small Claude-authored chart cards — the visuals a physics talk actually needs.

Figures & images

Diphoton mass spectrum (SVG asset).

A simulated event display.

Paste screenshots straight onto the canvas (Ctrl+V), or embed SVG/PNG as content-addressed assets — nothing is uploaded.

CUSTOM EMBED · WRITTEN BY CLAUDE · theme-aware

Charts that animate and update

An animated bar chart — click Shuffle and it tweens. Exports capture a clean static snapshot.

Fit a line, live

A real least-squares fit in the sandbox — drag the noise slider and watch a, b change.

SECTION 04

Live & interactive

The embed element runs real, Claude-written code in a sandboxed, no-network iframe — and it follows your deck theme.

CUSTOM EMBED · WRITTEN BY CLAUDE · editable knobs · theme-aware

Editable interactive widgets

The 'peak' knob shows up in the Inspector — turn it without touching code. Colours follow the deck theme.

CUSTOM EMBED · WRITTEN BY CLAUDE · theme-aware

A live terminal, rendered on a slide

Typed by a sandboxed script — no shell, no network. Great for walking through a workflow.

CUSTOM EMBED · WRITTEN BY CLAUDE · theme-aware

Physics toys that actually run

A double pendulum integrated every frame — restart from the same angles and it still diverges.

Interference, in real time

Two sine waves and their sum (accent) — slide the frequencies together to see beats.

CUSTOM EMBED · WRITTEN BY CLAUDE · theme-aware

Real 3D, fully self-contained

Flat-shaded, z-sorted, back-face culled — all in the sandbox. Drag to rotate; toggle wireframe.

print(f'peak = {popt[1]:.2f} GeV')     # -> 125.09 GeV

SECTION 05

Structure & flow

Diagrams and bound connectors — native structure that re-routes as you move things.

Diagrams

Mermaid source lives in deck.json; the editor renders and caches the SVG (Insert ▸ Diagram).

Connectors

Detector

DAQ

Grid storage

Analysis

Endpoints bind to a shape's side, so moving a box re-routes the arrow automatically.

SECTION 06

You + your AI

The deck is the single source of truth. You edit by hand, Claude edits over MCP — the same ops, the same live canvas.

How Claude edits your deck

You, in the terminal

“Add a slide comparing ATLAS and CMS limits, make the title red, and drop in the exclusion plot.”
