wtf is science-app?

This repository appears to be a science website hosted on GitHub Pages. It's a fairly minimal setup right now, mostly a template that GitHub provides when you first set up a Pages site. Here's what's happening: when you push content to this repository, GitHub automatically turns it into a live website. You write your content in Markdown (a simple text format), and Jekyll, a tool that converts text into web pages, builds everything into an actual website that people can visit in their browser. The README shows examples of how to format text with headers, bold, links, and images using Markdown syntax. The repo also mentions Heroku in passing, though the README doesn't explain how it's being used. The actual web app code (which would be written in JavaScript, based on the repository language) isn't documented in the README, so it's unclear what the site does beyond hosting content. If you're the owner of this repository, you'd use it to maintain a science-themed website without needing to write HTML or manage servers yourself. You'd edit Markdown files directly on GitHub or locally, commit your changes, and the site updates automatically. This is a good fit for blogs, documentation sites, or portfolio pages where the content is relatively static. To understand what this particular app actually does and what features it offers, you'd need to look at the actual code files in the repository or visit the deployed website.
