Another wonderful story by Nick Kristof in today's NYT:

OF all the students preparing to go to college this fall, perhaps none have faced a more hazardous journey than a young woman named Sultana. One measure of the hazard is that I'm not disclosing her last name or hometown for fear that she might be shot.

Sultana lives in the Taliban heartland of southern Afghanistan, and when she was in the fifth grade a delegation visited her home to warn her father to pull her out of school, or else she would have acid flung in her face. Ever since, she has been largely confined to her high-walled family compound — in which she has secretly, and perilously, educated herself.

"I'm unstoppable," Sultana laughs, and it's true: She taught herself English from occasional newspapers or magazines that her brothers brought home, in conjunction with a Pashto-English dictionary that she pretty much inhaled. When her businessman father connected the house to the internet, she was able to vault over her compound walls.

"I surrounded myself with English, all day," she told me by Skype. Today her English is fluent, as good as that of some Afghan interpreters I've used.

Once she had mastered English, Sultana says, she tackled algebra, then geometry and trigonometry, and finally calculus BC. She rises about 5 a.m. and proceeds to devour calculus videos from Khan Academy, work out equations, and even read about string theory.

Sultana, now 20, says she leaves her home only about five times a year — each time, she must wear a burqa and be escorted by a close male relative — but online she has been reading books on physics and taking courses on edX and Coursera.
