Mathematics didn't spring spontaneously to life, rules and definitions set in stone for all time. Its progress story has rich connections with measurement and money that have often shaped its development and driven its progress, a process that continues to this day. Quite Right explains how simple mathematical ideas have evolved all the way from prehistoric times so that they pervade almost every aspect of life in the 21st century. Most histories of mathematics look at the narrow role of professional mathematicians through the ages. Professor Biggs' sweeping tale is far wider. Making use of new discoveries of artefacts and documents, he reveals the part that mathematics has played in the human story and reflects on the nature of mathematics itself. The story reveals the power and beauty of mathematical concepts, which often belie their utilitarian origins. The twin paradigms of logical justification and algorithmic calculation recur throughout the book. Another theme is the relationship between mathematics and measurement of all kinds. No other book covers money and measurement in this way. Includes sections on: -- The origins of banking and interest in ancient Mesopotamia -- Using mathematics to keep secrets in medieval times -- The impact of tax and trade on the development of mathematics -- Financial speculation in our information age -- The role mathematics plays today in keeping you safe Quite Right is a fascinating story, suitable for anyone interested in the foundations of the mathematical world we live in. Norman Biggs is Professor (Emeritus) of Mathematics at the London School of Economics. He is the author of 12 books, including a perennial best-selling book Discrete Mathematics (Oxford University Press). He has a special interest in measurement and was Chair of the International Society of Weights and Scales Collectors from 2009-14. He served as a Vice President of the British Society for the History of Mathematics in 2014 and is an active member of the British Numismatic Society. 'This is a history of mathematics book with a difference. Instead of the usual chronological sequence of events, presented with mathematical hindsight (interpreting mathematical achievements from a modern point of view), this book tries to see things more from the context of the time - presenting the topics thematically rather than strictly chronologically, and including results and problems only when they fit into the themes EL the level of exposition is first-rate, with a far greater fluency than most mathematical writers can attain EL I am very happy to recommend it wholeheartedly.' Professor Robin Wilson, University of Oxford

In this slightly off-beat, deliberately challenging and striking oversized book, one of America's favourite artists offers up to 33 full-size paintings that portray scenes where things are, well, not quite right, but just enough so that most children will be able to spot the clever anomalies and paradoxes. Ages 8+.

"A beacon of truth and wisdom for the abused and a help in their healing." --Scot McKnight and Laura Barringer, authors of A Church Called Tov "Reading this book . . . will change you forever, for the better." --Rachael Denhollander, speaker, victim advocate, and author of What Is a Girl Worth? "Sincerely thoughtful, incredibly practical, and truly compassionate book on abusive systems and the consequences of cover-ups." --Christina Edmondson, PhD, cohost of Truth's Table podcast "Am I the only one who sees this--am I just imagining things? Is something wrong with me . . . or could this be abuse?" Maybe you don't know for sure: all you know is something feels off when you think about a certain relationship or interaction with an institution or organization. You feel alone and confused--but calling it "abuse" feels extreme and unsettling, a label for what happens to other people but not you. Yet you can't shake the feeling: something's not right. In his debut book, researcher and advocate Wade Mullen introduces us to the groundbreaking world of impression management--the strategies that individuals and organizations utilize to gain power and cover up their wrongdoings. Mullen reveals a pattern that accompanies many types of abuse, almost as if abusers are somehow reading from the same playbook. If we can learn to decode these evil methods--if we can learn the language of abuse--we can help stop the cycle and make abusers less effective at accomplishing destruction in our lives. Something's Not Right will help you to identify and describe tactics that were previously unidentifiable and indescribable, and give you the language you need to move toward freedom and create a safer future for yourself and others.
