Orientation
Begin with the voice
Three essays about why this site exists, what its author notices, and how small things become a way of thinking.
- 1 Why I Write What I Write A personal essay on writing, drawing, satire, darkness, digital obscurity, and the strange relief of forcing private weather into public shape. Personal Essay
- 2 Why I Write on Small Things A hot June afternoon in Calcutta turns into a funny, bruised, and unsentimental essay on depression, class humiliation, ordinary failure, and the stubborn need to keep naming life honestly. Personal Essay
- 3 Welcome To SuvroGhosh.IN A Kolkata-flavored blog manifesto about science, skepticism, satire, failure, bipolar weather, and the stubborn need to keep writing even when the room is empty. Personal Essay

Healthcare IT
Healthcare systems from first principles
Start with the human and institutional problems, then move into interoperability and information exchange.
- 1 Why You Still Want to Read a Healthcare IT Blog in the Age of AI An exploration of why human-written, skeptical, and curiosity-driven healthcare IT commentary remains indispensable in an era of AI-generated noise, marketing jargon, and technological conceit. Healthcare IT
- 2 FHIR and the Clerk With the Clipboard A Calcutta-grounded essay on FHIR, the health data standard that tries to make clinics, labs, apps, and public health systems speak to one another without losing meaning. Healthcare IT
- 3 HIE from First Principles A system-level dissection of Health Information Exchange (HIE) from first principles, using OpenHIE as the architectural lens. Healthcare IT

Science & mental models
Science without ceremonial fog
Mathematics, probability, and uncertainty explained through queues, myths, and the structures beneath ordinary problems.
- 1 Poisson Distribution: Counting Rare Trouble Before It Becomes a Queue, a Claim, or a Crisis A readable but technically serious healthcare IT post on the Poisson distribution, from its historical roots in rare-event counting to its everyday use in hospital operations, EHR analytics, patient safety, interface monitoring, epidemiology, and AI-era healthcare data. Healthcare IT
- 2 The Four Fundamental Subspaces of Linear Algebra A lucid, technically careful explanation of the four fundamental subspaces in linear algebra: column space, nullspace, row space, and left nullspace. The post treats a matrix not as a grid of numbers but as a machine for moving, losing, and exposing information. Mathematics
- 3 Why Myths Multiply When Randomness Is Left Unexplained A technically serious but readable argument for why ordinary people need a working grasp of randomness, chaos, and complexity, especially in a crowded, rumor-rich, infrastructure-fragile city like Calcutta. Mental Models

Place & memory
Calcutta, close up
Tea, schooling, heat, and the city as lived experience rather than scenery.
- 1 A Cup of Cha Is Not a Small Thing Tea looks like a humble brown drink, but inside that cup sits China, empire, stolen plants, Bengali roadside life, colonial labor, and the merciless physics of cooling. Essay
- 2 Schooling in Calcutta A Calcutta self-portrait stitched from school shame, books, reading, sketches, politics, survival, and the stubborn habit of staying mentally alive. Personal
- 3 The Calcutta Summer of 2026 A street-level, India-focused look at why Calcutta’s 2026 summer is not merely hot, but structurally dangerous: humidity, labor, housing, health surveillance, and the small tyrannies of daily life. Climate

Short fiction
Fiction after dark
Three unsettling stories in which Calcutta's streets, houses, and systems acquire lives of their own.
- 1 The Polished Ghost of Banamali Lane A faceless gentleman in a suit begins visiting corrupt men across Calcutta at night, leaving resignations, deaths, and a city drunk on justice. One failed writer discovers the ghost may not be hunting the people everyone thinks it is. Short Fiction
- 2 The Last Notification When a large asteroid is announced to be heading for Calcutta, a hospital data clerk notices that the city has begun recording deaths before they happen. In a city where everyone survives by looking away, the sky becomes only the second-worst thing falling. Short Fiction
- 3 The River Climbed the Stairs At Mallick Ghat on a furnace-bright morning, devotees enter the river for relief and find something older than prayer waiting below. When the thing climbs ashore, one man must decide whether the past is a wound, a warning, or a debt come due. Short Fiction
