Geometry class, but make it chaos
Byrne's Euclid
A gorgeous math glow-up has fans swooning while critics call it colorful chaos
TLDR: *Byrne’s Euclid* brings a colorful 1847 geometry classic online with interactive diagrams, posters, and puzzles. Commenters are split between loving the eye-catching design and calling it cluttered, with bonus drama over the old-fashioned letter style—because the internet can absolutely argue about math aesthetics.
A 19th-century math book just got the full internet thirst treatment. Byrne’s Euclid revives Oliver Byrne’s 1847 version of Euclid’s famous geometry text, complete with bright colored diagrams, interactive features, cross-references, posters, and even a puzzle. In plain English: it takes old-school shape-and-angle lessons and turns them into something that looks weirdly cool enough to hang on your wall. And yes, the comments immediately turned that into a personality test.
The loudest reaction was pure “where was this when I was failing geometry?” energy. One commenter said a colorful book like this would have made high school geometry far easier to understand, then delivered the most relatable plot twist of the thread: teenage them would never have believed adult them would one day crave a Euclid poster. That accidental comedy basically became the vibe. Other readers jumped in with the classic internet move of saying, actually, there’s an even more advanced version out there, complete with a link, because no online discussion is complete without someone bringing receipts.
But not everyone was ready to worship at the altar of colorful triangles. One critic said the rainbow-heavy diagrams felt distracting and cluttered, while another launched a tiny but deliciously nerdy revolt against the old-timey long s, calling it unnecessary. Add in one commenter resurfacing older discussions like a forum historian, and the result is peak internet culture: half the crowd wants to buy the poster, half wants cleaner pages, and everyone somehow has a strong opinion about how geometry should look.
