How much power does your human engine have? How much power do you need for running in different conditions? How can you optimize your training and racing performance? How can you use power meters to improve your results? What are the ultimate limits of human performance? The Secret of Running answers all of these questions. All factors determining the performance in running (from 800-meter race to marathon) are explained step by step: training, nutrition, body weight, running form, wind, hills, temperature, running gear, power meters and much more. Written in a crystal-clear and lively style, this book is a wealth of information for every ambitious runner. This title also contains brand new insights on how the balance of the power of your human engine and the power requirement for running in different conditions determines your performance. It shows how power meters can be used to optimize your training, running economy and race result. This book is lavishly illustrated and packed with useful data. Being already a bestseller in the Netherlands and Belgium, The Secret of Running can be considered the ultimate textbook for all serious runners and their coaches.

This book gives an account of geological aspects of windblown material. Aeolian processes play an important role in modifying the surface of the Earth, and they are also active on Mars. Additionally, they are thought to occur on Venus and possibly Titan as well. The authors describe the following aspects: wind as a geological process, the aeolian environment, physics of particle motion, aeolian abrasion and erosion; aeolian sand deposits and bedforms, interaction of wind and topography and windblown dust. A particular strength of the book is that it deals with aeolian processes in a planetary context, rather than as a purely terrestrial phenomenon. In so doing, the authors ably demonstrate how we can gain better understanding of the Earth through comparative planetology. This paperback reissue will enable the book to be used as a text for advanced students in planetary science. Special terms are defined when they are first used. There is a glossary and an exhaustive bibliography.

An electric resistance air heater for wind tunnel 4 of the Aeronautical Sciences Laboratory at the University of California was constructed and proven satisfactory in performance tests. The heater increased the range of stagnation temperature to 1600 F, thereby increasing the experimental range of test conditions of the wind tunnel to include higher Mach numbers, deeper penetration of the slip flow region, and temperatures more nearly simulating free flight conditions.
