From the Preface by V. S. VARADARAJAN: These volumes of the Collected Papers of Harish-Chandra are being brought out in response to a widespread feeling in the mathematical community that they would immensely benefit scholars and research workers, especially those in analysis, representation theory, arithmetic, mathematical physics, and other related areas. lt is hoped that in addition to making his contributions more accessible by collecting them in one place, these volumes would help focus renewed attention on his ideas and methods as well as lend additional perspective to them....

In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste of time, something that could have been avoided by a systematic and proper geophysical approach. The combination of various geophysical techniques with environmental conditions is essential to constrain the interpretation and reduce...

The Canal du Midi, which threads through southwestern France and links the Atlantic to the Mediterranean, was an astonishing feat of seventeenth-century engineering--in fact, it was technically impossible according to the standards of its day. Impossible Engineering takes an insightful and entertaining look at the mystery of its success as well as the canal's surprising political significance. The waterway was a marvel that connected modern state power to human control of nature just as surely as it linked the ocean to the sea.

The Canal du Midi is typically characterized as...
