Book Description
How do you measure the size of the planet you're standing on? "Circumference" is the story of what happened when one man asked himself that very question. Nicholas Nicastro brings to life one of history's greatest experiments when an ancient Greek named Eratosthenes first accurately determined the distance around the spherical earth. In this fascinating narrative history, Nicastro takes a look at a deceptively simple but stunning achievement made by one man, millennia ago, with only the simplest of materials at his disposal. How was he able to measure the land at a time when distance was more a matter of a shrug and a guess at the time spent on a donkey's back? How could he be so confident in the assumptions that underlay his calculations: that the earth was round and the sun so far away that its rays struck the ground in parallel lines? Was it luck or pure scientific genius? Nicastro brings readers on a trip into a long-vanished world that prefigured modernity in many ways, where neither Eratosthenes' reputation, nor the validity of his method, nor his leadership of the Great Library of Alexandria were enough to convince all his contemporaries about the dimensions of the earth. Eratosthenes' results were debated for centuries until he was ultimately vindicated almost 2000 years later, during the great voyages of exploration. "Circumference" is a compelling scientific detective story that transports readers back to a time when humans had no idea how big their world was--and the fate of a man who dared to measure the incomprehensible.

Book Description
Endorsements: Dr. Montgomery's latest book is one that every serious reader interested in clear Christian thinking should have on a table near her most comfortable reading chair. It is filled with a wide variety of bite-sized essays that are absolutely delightful --knowledgeable, fun, witty, and unexpected. If you have never read the work of J. W. Montgomery before, you are in for a treat. This is a book that brings together his best writing from the past with his latest essays. It's a Christian feast of ideas that celebrates our Lord and His unfailing Word. --Craig J. Hazen, Ph.D., Director, MA Program in Christian Apologetics, Biola University What makes J. W. Montgomery tick? What has driven him over a massively productive career to such wide-ranging interests as computers and Chemnitz, legal theory and apologetics, human rights and Christology, Dawkins and Duchamp? The answer is clear: the gospel of Jesus Christ and its defense, articulation, and application to the real world in which the Word became flesh, died, and rose again as the Savior. Many of our best confessional-era theologians, both Lutheran and Reformed, were ""Renaissance men,"" but that's rarely the case today. Dr. Montgomery is a glaring exception and this book is a wonderful display of that full scope of his remarkable insights. While being an ardent defender of the Lutheran confession, he is far from parochial. Even in places where one might disagree, the clarity, logic, and relentless rigor of his arguments will kindle fires in hearths that we didn't even know we had and make us better advocates for the gospel. --Dr. Michael Horton, J. Gresham Machen Professor of Systematic Theology and Apologtics, Westminster Seminary California About the Contributor(s): John Warwick Montgomery is Professor Emeritus of Law and Humanities, University of Bedfordshire, England, Distinguished Research Professor of Philosophy and Christian Thought, Patrick Henry College (Virginia, U.S.A.), and Director, International Academy of Apologetics, Evangelism and Human Rights (Strasbourg, France). He holds ten earned degrees besides a Doctorate in Philosophy from the University of Chicago, the Doctorat d'Universit from Strasbourg, France, and the LL.M. and LL.D. from the University of Cardiff, Wales/UK. A frequent contributor to Christianity Today, Dr. Montgomery has been honored by inclusion in Who's Who in America, Who's Who in France, and The Dictionary of International Biography.
