200% of Nothing : An Eye-Opening Tour through the Twists and Turns of Math Abuse and Innumeracy

Acclaim for "In today's world, 'innumeracy' is an even greater danger than illiteracy, and is perhaps even more common. Advertisers and politicians exploit it; intellectuals (self-styled) even flaunt it. I hope that this wise and witty book will provide cures where they are possible, and warnings where they are necessary.

"It's also a lot of fun. I can guarantee that 100%."--Arthur C. Clarke

"Dewdney retells with charm and wit magnificent morsels of mathematical mayhem discovered by his army of volunteer 'abuse detectives.' From 'sample trashing' to 'numerical terrorism,' from 'percentage pumping' to 'dimensional dementia,' 200% of Nothing plumbs the depths of innumeracy in daily life and reveals what ordinary people can do about it.

A rich, readable, instructive, and persuasive book."--Lynn Arthur Steen, Professor of Mathematics, St. Olaf College
