She spent a year in Dehradun learning what her father had known.
Tides and tidal streams. The mathematics of position-fixing. The care that goes into a single sounding: the calibration, the correction for temperature, the log of every cast. There were thirty students, mostly young men, mostly from the navy, and for three months they treated her as a curiosity. Then in the second term the class went out on a survey exercise and she found a discrepancy in a reading that the instructors had missed.
"How did you spot it?" asked the lecturer, a stern woman with an unfashionable bun.
"I don't know," said Isha. "It didn't look like the sea."
The woman looked at her for a long moment. "That is the only qualification that matters," she said.
