Science should be accessible.

We aim to meet WCAG 2.1 AA. This is an accessibility commitment, not a claim of independent certification or a completed compliance audit.

Use the skip-navigation link to reach page content. Navigation, filters, forms and demonstrations are keyboard accessible. Focus indicators identify the active control. The website supports light and dark themes.

Interactive geometry has adjacent textual controls and descriptions. Drag to rotate, or focus a scene and use the arrow keys. If WebGL is unavailable, the explanatory content remains accessible. Enable reduced motion in your device settings to stop automatic scene rotation and use manual story progression.

Films play only when requested and can be paused. They are conceptual, silent animations; descriptive labels identify their subject. Scientific previews are illustrative, not validated experimental data.

If you encounter a barrier, please describe the page, your device and assistive technology so we can investigate.
