Been working on a visual proof for why three particular angles always sum to exactly 45°. Built it in Manim, trying to let the geometry speak rather than over-explain. Would love feedback on whether the pacing of the reveal works, or if the construction feels too abrupt.
Built an animated proof showing how placing a point at exactly 15° base angles inside a square forces a perfect equilateral triangle at the top.
The whole thing hinges on tan(15°) = 2 − √3, which is one of those identities that feels like it shouldn't work out so cleanly.
Made with Manim, feedback welcome!
Latest from my math-teasers pipeline: the geometric intuition behind
the power rule. Square of side x, nudge by dx, watch the area change
decompose into 2x·dx + dx².
Automated with human in loop: script→ manim.py → TTS sync → final video.
I hold a master's in physics, but these days I spend my hours wrangling big data pipelines as a data engineer. In the quieter hours, I've been building something that merges both worlds an automated pipeline that generates math puzzle videos using Manim.
The idea is simple: feed it a puzzle, and it produces the full video scripted narration, animated scenes, voiceover, the works. Still early days, and there's plenty of rough edges. But the pipeline is real and producing videos end to end. Videos will show dramatic improvements within weeks!
Would love feedback from this community on the animations, the approach, anything really. Happy to talk about the technical side if anyone's curious.
