Blair suggests that our belief systems are on the threshold of change, as we create new myths that encompass both the emotional and rational sides of human nature.

5. 1. 1 Biological Rhythms and Clocks From an evolutionary perspective, the adaptation of an organism’s behavior to its environment has depended on one of life’s fundamental traits: biological rhythm generation. In virtually all light-sensitive organisms from cyanobacteria to humans, biological clocks adapt cyclic physiology to geophysical time with time-keeping properties in the circadian (24 h), ultradian (24 h) domains (Edmunds, 1988; Lloyd, 1998; Lloyd et al. , 2001; Lloyd and Murray, 2006; Lloyd, 2007; Pittendrigh, 1993; Sweeney and Hastings, 1960) By definition, all rhythms exhibit regular periodicities since they constitute a mechanism of timing. Timing exerted by oscillatory mechanisms are found throughout the biological world and their periods span a wide range from milliseconds, as in the action potential of n- rons and the myocytes, to the slow evolutionary changes that require thousands of generations. In this context, to understand the synchronization of a population of coupled oscillators is an important problem for the dynamics of physiology in living systems (Aon et al. , 2007a, b; Kuramoto, 1984; Strogatz, 2003; Winfree, 1967). Circadian rhythms, the most intensively studied, are devoted to measuring daily 24 h cycles. A variety of physiological processes in a wide range of eukaryotic organisms display circadian rhythmicity which is characterized by the following major properties (Anderson et al. , 1985; Edmunds, 1988): (i) stable, autonomous (self-sustaining) oscillations having a free-running period under constant envir- mental conditions of ca.

Based on the award-winning PBS documentary series, Ring of Fire is this first-person account of the adventures of two English brothers as they explore the astonishingly rich cultures of the Indonesian archipelago. Their fascinating odyssey began in 1972 with a 2,500-mile voyage through the fabled Spice Islands, in search of the Greater Bird of Paradise. A decade of further exploration followed, during which the brothers lived among the Asmat cannibals of Papua and the healers of Bali, came face-to-face with the man-eating dragons of Komodo, and encountered the elusive dream wanderers of Borneo. Amid impenetrable rain forests, erupting volcanoes and startling natural beauty, the brothers have captured on film and in words the story of one of the most captivating and intriguing explorations ever made.
