Flight Without Limits Large-Format Edition (Magazine Style) The novel is Science Fiction - a space journey with the freedom to move, to love, to choose, to live. Imagine, traveling in an instant to wherever you want to be! The universe is your playground. Thought becomes expression. This is science fiction indeed. But maybe mentally it shouldn't be. The novel is about a space voyage to Alpha Centauri, the nearest solar system to our own. It starts as a high tech voyage, and then becomes much more than that. It links up with a future that is moving backwards. It also comes upon a present that has no future, but for which a future is created that has no limits. Of course, being able to travel to wherever one may want to be has certain social advantages, and also challenges. Of course, politically, this capability has even greater challenges attached. Some people say that we will never have the capability, to go physically in an instant wherever we want to be. They might be right. But we do have that kind of capability mentally, in the world of science, romance, and spirituality, all of which are threaded through the novel. You may find that when you return, you have left some of the old limits behind. (http: //www.ice-age-ahead-iaa.ca


Biologic Effects Of Light 2001

As humans ventured into the twentieth century, the industrialized countries were confronted with the scourge of rickets. Although solariums were becoming common in the early 1900s and phototherapy was gaining popularity as a result of the awarding of a Nobel Prize to Finsen in 1903, it wasn't until 1921 when Hess and Unger demonstrated that rickets could be cured by exposure to sunlight that the healthful benefit of sun exposure appreciated. In 1941, Apperly (Cancer Research; 1: 191-195, 1941) noted that the occasional increased risk of skin cancer was associated with a decreased risk of many other more common and serious cancers. The alarming increase in the number of cases of skin cancer, especially melanoma, has caused great concern about the negative role of sunlight in health. The Sixth International Arnold Rikli Symposium on the Biologic Effects of Light was held in Boston, Massachusetts from June 16th - 18th, 2001. The goal of this Symposium was to focus on the very popular practice of tanning either by sunlight or by artificial light sources and the overall impact this practice has on health and disease. The program was organized by members of the Scientific Advisory Committee and my co-chair emeritus, Professor Ernst G. Jung. The Program Committee organized an outstanding state-of-the-art program that was enthusiastically received by the participants.
