Sir Isaac Newton is one of history's most renowned scientists. He independently developed the mathematical technique known as Calculus, wrote a treatise on the properties of light and color that is still consulted by scientists, and worked out the mathematical details of the law of gravity. What is less well known is the depth of his Christian faith, and the amount of writing, speaking, and research he devoted to defenses of the tenets of Biblical belief. This book makes Newton come alive for readers. From the detailed account of the events that led to his conversion, his Christian faith plays a central role in this biography, as it did in his life.
