Build interactive science explainers with just markdown
pie is a Markdown-based static site generator for interactive science explainers: Python, a live canvas, autodiff and animation in plain Markdown pages.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
