The Language of Rain
Rain is chemistry, physics, and the water cycle made visible. At our Varanasi school, children learn both the science and poetry of monsoon.

When the Monsoon Arrives
There is a particular smell that arrives before the rain does. Petrichor — a word coined in 1964 by two Australian scientists — describes the earthy scent produced when rain meets dry soil. It is caused by geosmin, a compound released by actinobacteria in the earth, and by ozone carried down from the upper atmosphere by the falling drops.
Kalidasa wrote about this smell in the Meghaduta in the 4th century CE, long before anyone named the compound. He wrote about a cloud as a messenger carrying longing across the sky, and every reader in the subcontinent knew immediately what he meant — because they had all stood in that first rain and felt it.
This is what it means for science and literature to speak the same language.
The smell of rain on dry earth has a name: petrichor. It comes from a chemical called geosmin made by soil bacteria — your nose can detect it at just 5 parts per trillion.
Rain as Physics
A single raindrop falls at about 9 metres per second. Terminal velocity — the point where drag equals gravity. Without air resistance, a raindrop falling from a cloud at 2,000 metres would hit the ground at 200 km/h, like a small bullet. Instead, air slows it to a gentle tap on the skin.
This is not a trivial fact. It is a doorway. A child who asks why does rain not hurt? has just encountered fluid dynamics, gravity, and atmospheric physics — all before breakfast.
The monsoon brings 75% of India's annual rainfall in roughly 100 days. It regulates the temperature of an entire subcontinent. It fills rivers that 1.4 billion people drink from. It is, in many ways, the real government of India — more consequential than any parliament.
Did you know? A single monsoon cloud system can carry 500 million tonnes of water across the sky. The entire Indian monsoon delivers roughly 4,000 cubic kilometres of rain each season — enough to fill every river on Earth for weeks.
Rain as Literature
In Tamil Sangam poetry, the five classical landscapes each had their own rain — kurinji (mountain), mullai (forest), marudam (pastoral), neytal (coastal), paalai (desert/summer). Each rain carried its own emotion, its own season, its own kind of longing.
In Urdu, there is a whole vocabulary of rain: baarish, barsat, rim jhim, saawan. Each word carries a different weight, a different music.
Did you know? The Sanskrit word for cloud, megha (मेघ), is the root of Kalidasa's Meghaduta — "Cloud Messenger" — written in the 4th century CE. It is one of the oldest poems ever written about longing, and it uses a cloud as its protagonist.
When we teach a child to hear the difference between a summer shower and the first monsoon downpour, we are teaching them to listen. And a child who listens carefully — to rain, to words, to people — is equipped for almost everything.
A School That Teaches Both
At Akshararambh, we want our students to walk into the monsoon and come back with both a question and a poem. To know the water cycle and also to have once sat in the school courtyard watching rain collect in the leaves of a neem tree, going nowhere in particular, just watching.
Because a scientist without wonder is just a technician. And a poet without curiosity is just decorating the surface of things.
Rain teaches both, if you let it.
