This book is mainly a collection of essays I published between 2001 and 2013. Most of those essays appeared on VDARE.com, an online magazine dedicated to frank discussion of the National Question. The penultimate essay in this collection defines the National Question and offers an answer to it. That essay also describes the work of VDARE.com in more detail. It concludes with an unofficial VDARE.com mission statement.

Nell'agosto 1859 Bernhard Riemann, matematico giovane e ancora poco noto, presentò all'Accademia di Berlino un articolo intitolato "Sul numero di primi minori di una grandezza data". In quella circostanza discusse per la prima volta l'ipotesi che prende il suo nome e che è ancora oggi, a centocinquant'anni di distanza, uno dei più famosi problemi irrisolti della matematica. Dimostrare questa ipotesi permetterebbe di trovare una formula per gen...

La protagonista di questa storia, lunga ben 4000 anni, è la X. L'ignota quantità che abbiamo incontrato per la prima volta nelle equazioni di primo grado fino alle più complicate formule matematiche. Ma cosa si nasconde dietro questo simbolo astratto? Tutta la storia dell'algebra, dalla comparsa del pensiero algebrico, tra il XVIII e il XVII secolo a.C., passando dalla Mesopotamia all'Egitto alla Grecia, facendo tappa per le isole di Vittoria,...

A brilliant and sparklingly original account of algebra through the ages, by one of mathematics' great popularizers: 'Unknown Quantity buzzes with rivalries, frustrations and breakthroughs ... A first-rate account that even algebraphobes will struggle to fault.' New Scientist

Perfect for history buffs and armchair algebra experts, Unknown Quantity tells the story of the development of abstract mathematical thought.John Derbyshire discovers the story behind the formulae, roots, and radicals. As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves...

The definitive story of the Riemann Hypothesis, a fascinating and epic mathematical mystery that continues to challege the world. In 1859, Bernhard Riemann, a little-known thirty-two year old mathematician, made a hypothesis while presenting a paper to the Berlin Academy titled "On the Number of Prime Numbers Less Than a Given Quantity." Today, after 150 years of careful research and exhaustive study, the Riemann Hyphothesis remains unsolved,...

To his fellow conservatives, John Derbyshire makes a plea: Don't be seduced by this nonsense about "the politics of hope." Skepticism, pessimism, and suspicion of happy talk are the true characteristics of an authentically conservative temperament. And from Hobbes and Burke through Lord Salisbury and Calvin Coolidge, up to Pat Buchanan and Mark Steyn in our own time, these beliefs have kept the human race from blindly chasing its utopian dream...
