Because these geometrical factors could be de\u00ac rived from Pilgrim\u2019s results, Milankovitch concluded that it should also be possible to describe mathematically the distribu\u00ac tion of solar radiation onto the surface of the planets. Although simple in principle, the task of making these calcula\u00ac tions proved to be enormously difficult in practice. For all of the planets are constantly spinning, revolving, wobbling and tilting in a crazy celestial dance, every movement of which has some effect on the radiation they receive from the sun.<\/p>\n

But Milankovitch was 32 years old and confident of his powers. Later he wrote: \u201cI set out on this hunt in my best years. Had I been somewhat younger I would not have possessed the necessary knowledge and experience …. Had I been older I would not have had enough of that self-confidence that only youth can offer in the form of rashness.\u201d<\/p>\n

At first, Milankovitch\u2019s investigations went well. \u201cBut in trying to penetrate more deeply into the problem, I ran into difficulties and could get no further,\u201d he wrote later. \u201cThen [in 1912] the First Balkan War broke out. The Danube division of the Serbian Army, to whose staff I had been assigned, crossed the border of what was then the Turkish Empire early in the morning and was planning to capture Starac Mountain.\u201d<\/p>\n

As the young mathemati\u00ac cian watched the Serbian troops fight their way toward the sum\u00ac mit of the mountain, his thoughts turned to his own scientific attack, and the theoretical obstacles he had been unable to sur\u00ac mount. Then, as the Serbian regiment took the summit of Starac Mountain, the solution to his mathematical difficulties flashed into his mind, and he \u201cconquered a mountaintop\u201d on his own internal battlefield.<\/p>\n

Two days later, the Turks were defeated. A cease-fire ensued, and Milankovitch was able to return to his private battle in the library in Belgrade. Although his progress now was rapid, he realized that it would be several years before his second major objective was attained. Keenly aware of the uncertain political atmosphere in the Balkans, he decided that he should go no further with his calculations until he had set down on paper the results he had obtained thus far. These were published as three short treatises during the years 1912 and 1913.<\/p>\n

Early in 1914, Milankovitch published another article, \u201cOn the Problem of the Astronomical Theory of the Ice Ages.\u201d Written in Serbian, and appearing in the midst of political turmoil in Europe, this article Ice Ages: Solving the Mystery remained in scientific obscurity for many years.<\/p>\n

PREFACE Knowledge that the world once endured an ice age has been widespread for more than a century. Indeed, the concept is now so familiar that nearly every winter storm prompts dra\u00ac matic headlines: Is a new ice age upon us? This book tells the story of the ice ages\u2014what they were like, why they occurred, and when the next one is due. It is a tale of scientific discovery, and therefore a book about people\u2014about the astronomers, geochemists, geologists, paleontologists, and geophysicists from a dozen countries who have been engaged for nearly a century and a half in the search for a solution to the ice-age mystery.<\/p>\n

We are indebted to many people for their advice and assis\u00ac tance in the preparation of this book. In particular we wish to thank Vasko Milankovitch for sharing with us his memories of his father, Milutin Milankovitch. Tatomir P. Angelitch of the Serbian Academy of Sciences and Arts was kind enough to pro\u00ac vide us with a complete list of Milankovitch\u2019s publications. Bar\u00ac bara Gronquist translated many passages from the German. Gordon Craig of the University of Edinburgh helped locate information about James Croll.<\/p>\n

The studies by Albert V. Ca- rozzi of the University of Illinois were an invaluable guide to the early development of the glacial theory. Catherine Krause located obscure sources that contributed greatly to this book. Many people put their personal recollections at our disposal. Among them were William A. Berggren, Wallace S. Broecker, Rose Marie Cline, Cesare Emiliani, Samuel Epstein, David B.<\/p>\n

Ericson, Rhodes W. Fairbridge, James D. Hays, George J. Ku- kla, Robley K. Matthews, Neil D. Opdyke, Nicholas J. Shack- leton, and Manik Talwani.<\/p>\n<\/blockquote>\n
