What mathematics can offer students: an enriched and transformed life. —A note from the authors, Edward B. Burger and Michael Starbird

Mathematicians encounter surprising and fascinating ideas such as infinity, chaos, fractals, the fourth dimension, rubber sheet geometry, coincidences, and other intriguing topics on a daily basis. These ideas portray effective strategies in everyday thinking that add value to how people make real-life decisions in areas of love and business to art and politics. We wrote The Heart of Mathematics: An Invitation to Effective Thinking to make truly big and beautiful ideas accessible to all students and to give instructors the chance to offer their students delectable math morsels.

Reactions to The Heart of Mathematics: An Invitation to Effective Thinking:

FROM FACULTY:

• "Heart of Mathematics is easily the best liberal arts math textbook I've ever used." —Shippensburg University
• "This is very possibly the best mathematics for the non-mathematician book that I've seen." —American Mathematical Monthly
• "For me this book has changed our 'liberal arts math class' from a dreaded assignment to something that is lively and interesting every time." —Buffalo State College

FROM STUDENTS:

• "This is far and away the best mathematics textbook I've ever used."
• "This class was not like any other math class. It allowed me to become creative and imaginative."
• "This math book is incredible. It teaches you math in the purest sense of the word. Also, it was funny and challenging."

The goal of education is to improve students' ability to think, and The Heart of Mathematics does just that—inviting students to think about how mind-changing ideas can transform lives.
