Because we have ten fingers, grouping by ten seems natural, but twelve would be better for divisibility, and eight is well suited to repeated halving. Grouping by two, as in binary code, has turned out to have its own remarkable advantages.
Paul Lockhart presents arithmetic not as rote manipulation of numbers―a practical if mundane branch of knowledge best suited for filling out tax forms―but as a fascinating, sometimes surprising intellectual craft that arises from our desire to add, divide, and multiply important things. Passionate and entertaining, Arithmetic invites us to experience the beauty of mathematics through the eyes of a beguiling teacher.More info →
A River Runs Through It
From its first magnificent sentence, "In our family, there was no clear line between religion and fly fishing", to the last, "I am haunted by waters", A River Runs Through It is an American classic.

Inferno (The Divine Comedy)
An extraordinary new verse translation of Dante’s masterpiece, by poet, scholar, and lauded translator Anthony Esolen
Of the great poets, Dante is one of the most elusive and therefore one of the most difficult to adequately render into English verse. In the Inferno, Dante not only judges sin but strives to understand it so that the reader can as well. With this major new translation, Anthony Esolen has succeeded brilliantly in marrying sense with sound, poetry with meaning, capturing both the poem’s line-by-line vigor and its allegorically and philosophically exacting structure, yielding an Inferno that will be as popular with general readers as with teachers and students. For, as Dante insists, without a trace of sentimentality or intellectual compromise, even Hell is a work of divine art.
Esolen also provides a critical Introduction and endnotes, plus appendices containing Dante’s most important sources—from Virgil to Saint Thomas Aquinas and other Catholic theologians—that deftly illuminate the religious universe the poet inhabited.More info →

The Martian – classroom edition
"Six days ago, astronaut Mark Watney became one of the first people to walk on Mars.
Now, he's sure he'll be the first person to die there.
After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he’s alive—and even if he could get word out, his supplies would be gone long before a rescue could arrive.
Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment, or plain-old "human error" are much more likely to kill him first."More info →
Prisoners of Geography: Ten Maps That Explain Everything About the World (Politics of Place)
Offering “a fresh way of looking at maps” (The New York Times Book Review), Marshall explains the complex geo-political strategies that shape the globe. Why is Putin so obsessed with Crimea?
