It's Only a Bubble aims at the liberation of man from his conviction that he suffers because he is inherently sinful. The traditional religious idea that man fell from the state of perfection that he was made by God is replaced by the idea that man was made perfect in the “core field,” but he was simultaneously placed in the “dimensions” for gaining perfection also by free choice. Man moves up the dimensions by evolving, which is achieved by growing over obstacles. Obstacles are not punishments by God, but stimulation for growth. God does not interfere directly, because He wants man to act so that he can grow. Help is not offered as a result of faith or prayers but is embedded in the creation and is released automatically as one grows. The author walks the readers through the process of facing obstacles, including overwhelming events, like death. He also identifies the benefits of moving up the steps of spiritual evolution and describes how formal education can become meaningful, if it’s finally made an integral part of growth.
Heat Transfer Characteristics of a Bubble-induced Water Jet Impinging on an Ice Surface
Winter freezing temperatures have posed many problems in certain regions for navigation, and for maintenance of structures in water. During long, cold winters many lakes, harbors, ports and rivers become covered with ice, greatly shortening the navigation period. In attempts to solve this problem, air-bubbler devices have been developed which operate on the principle that warm subsurface water can be brought to the surface by a stream of air bubbles rising through the otherwise quiescent bodies of water. The first air bubbler system was installed in 1917 at the Keokuk Dam, and since that time a number of similar usages have been reported. To the best of the author's knowledge, no prior laboratory work has been done regarding the heat transfer characteristics of a bubble-driven jet impinging on an ice surface. This work is also considered to be useful in destratifying lakes and artificial water reservoirs for control and upgrading of our water resources. The present study investigated the problem experimentally. The effects of column height, diameter and air bubbling rate on the rate of heat transfer were determined.
New Perspectives on Asset Price Bubbles
This volume critically re-examines the profession's understanding of asset bubbles in light of the global financial crisis of 2007-09. It is well known that bubbles have occurred in the past, with the October 1929 crash as the most demonstrative example. However, the remarkably well-behaved performance of the US economy from 1945 to 2006, and, in particular during the Great Moderation period of 1984 to 2006, assured the economics profession and monetary policymakers that asset bubbles could be effectively managed with little or no real economic impact. The recent financial crisis has now triggered a debate about the emergence of a sequence of repeated bubbles in the Nasdaq market, housing market, credit market, and commodity markets. The realities of the crisis have intensified theoretical modeling, empirical methodologies, and debate on policy issues surrounding asset price bubbles and their potentially adverse economic impact if poorly managed. Taking a novel approach, the editors of this book present five classic papers that represent accepted thinking about asset bubbles prior to the financial crisis. They also include original papers challenging orthodox thinking and presenting new insights. A summary essay highlights the lessons learned and experiences gained since the crisis.
