保罗·洛克哈特（Paul Lockhart）在大概十四岁时对数学产生兴趣（他特别指出，不是由于学校的数学课程），并开始大量的阅读。大学上了一个学期，他就退学，以专心研究数学，同时靠编程和当小学老师维生。后来他与加州大学洛杉矶分校的数学家恩斯特·施特劳斯（Ernst Strauss）合作，一同发表了多篇论文，并成为该校的研究生。1990年在哥伦比亚大学获得博士学位后，他先后在加州大学伯克利分校的数学科学研究中心（MSRI）和布朗大学任职，并在加州大学圣克鲁斯分校任教。他当时的主要研究方向是自守形式和丢番图几何。在高校教授数学多年后，他开始厌倦，决定回去教小孩子。他在2000年加入纽约的独立学校圣安妮学校（Saint Ann's School），并任教至今。

For seven years, Paul Lockhart's A Mathematician's Lament enjoyed a samizdat-style popularity in the mathematics underground, before demand prompted its 2009 publication to even wider applause and debate. An impassioned critique of K--12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here Lockhart offers the positive side of the math education story by showing us how math should be done. Measurement offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living. In conversational prose that conveys his passion for the subject, Lockhart makes mathematics accessible without oversimplifying. He makes no more attempt to hide the challenge of mathematics than he does to shield us from its beautiful intensity. Favoring plain English and pictures over jargon and formulas, he succeeds in making complex ideas about the mathematics of shape and motion intuitive and graspable. His elegant discussion of mathematical reasoning and themes in classical geometry offers proof of his conviction that mathematics illuminates art as much as science. Lockhart leads us into a universe where beautiful designs and patterns float through our minds and do surprising, miraculous things. As we turn our thoughts to symmetry, circles, cylinders, and cones, we begin to see that almost anyone can "do the math" in a way that brings emotional and aesthetic rewards. Measurement is an invitation to summon curiosity, courage, and creativity in order to experience firsthand the playful excitement of mathematical work.
