Is there always a prime number between $n$ and $2n$? Where, approximately, is the millionth prime? And just what does calculus have to do with answering either of these questions? It turns out that calculus has a lot to do with both questions, as this book can show you. The theme of the book is approximations. Calculus is a powerful tool because it allows us to approximate complicated functions with simpler ones. Indeed, replacing a function locally with a linear--or higher order--approximation is at the heart of calculus. The real star of the book, though, is the task of approximating the number of primes up to a number $x$. This leads to the famous Prime Number Theorem--and to the answers ...
"Before he enlisted as a soldier in the Iran-Iraq war and disappeared, Amir Yamini was a carefree playboy whose only concerns were seducing women and riling his religious family.

Piecing together the puzzle of his past, Amir decides theres only one solution: he must return to the battlefield and find the remains of his severed arm-- and discover its secrets"--Amazon.com.
An incredibly imaginative yet always charming love story set in contemporary Iran that crackles with wit, verve and social comment 'A brilliant novel about the complexities of writing and publishing in Iran' Guardian 'Rich and riveting' Irish Times 'This important, timely novel is sharp, playful and zesty with life' Daily Mail 'A meditation on the interplay of life and art, reality and fiction' New York Times 'Mandanipour's writing is exuberant, bonhomous, clever... powerful' New Yorker Sara falls in love with Dara through secret messages hidden in code in the pages of books that have been outlawed, but then something quite extraordinary and unexpected happens. Through adeptly handled asides to the reader, as well as anecdotes, codes and metaphors, and cheeky references to the wonderfully rich Iranian literary heritage, the novel builds to offer a revealing yet often playful and hopeful comment on the pressures of writing within the tightly prescribed Islamic regime, pressures that naturally are heightened where affairs of the heart are concerned.
NATIONAL BOOK AWARD LONGLIST The first English-language story collection from “one of Iran’s most important living fiction writers” (Guardian), “a playful, whip-smart literary conjuror: a Kundera or Rushdie of post-Khomeini Iran” (Wall Street Journal) In Seasons of Purgatory, the fantastical and the visceral merge in tales of tender desire and collective violence, the boredom and brutality of war, and the clash of modern urban life and rural traditions. Mandanipour, banned from publication in his native Iran, vividly renders the individual consciousness in extremis from a variety of perspectives: young and old, man and woman, conscript and prisoner. While delivering a ferocious social critique, these stories are steeped in the poetry and stark beauty of an ancient land and culture.
