A collection of 100 tongue-in-cheek (yet oddly accurate) equations that model the beautiful chaos of software development.
This is your unofficial developer physics engine — balancing caffeine, meetings, deadlines, and dreams.
From productivity and debugging, to cognitive load, burnout, and system resilience — it's all math now.
💡 All equations are in LaTeX-style math, rendered in Markdown using
$$...$$.
