Many paths.
Room to grow.
Medicine, Physics, Chemistry, and History now have dedicated sections. Plainly History is an opening route, with many more regions, periods, and perspectives to expand on later.
Four fields. One library.
Explore medicine and physics, follow chemical ideas from atoms to electrochemistry, or move through twenty-one history chapters. Each branch keeps its own visual identity, with more areas planned.
