I’m Raghu Ugare — an architect, developer and incurably curious learner. I write about mathematics, physics, programming, AI, music, poetry, patterns and whatever else refuses to stay inside a neat disciplinary box.

Biscuits in Tea is also a reminder to notice ordinary things. A beautiful proof deserves attention. So does a raag. So does a well-designed program. And sometimes so does the precise instant when a biscuit has absorbed enough chai but has not yet surrendered to gravity.

This is a living commonplace book rather than a finished encyclopaedia: essays, visual explanations, quotations, fragments, experiments and moments worth lingering over.
