Convergence is a history of modern science with an original & significant twist Various scientific disciplines despite their very different beginnings & disparate areas of interest have been coming together over the past 150 years converging & coalescing to identify one extraordinary master narrative one overwhelming interlocking coherent story the history of the universe Intimate connections between physics & chemistry have been revealed as have the links between quantum chemistry & molecular biology Astronomy has been augmented by particle physics psychology has been increasingly aligned with physics with chemistry & even with economics Genetics has been harmonised with linguistics botany with archaeology climatology with myth This is a simple insight but one with profound consequences Convergence is as Nobel Prize-winning physicist Steven Weinberg has put it The deepest thing about the universe' This book does not however tell the story by beginning at the beginning & ending at the end It is much more revealing more convincing & altogether more thrilling to tell the story as it emerged as it began to fall into place piece by piece converging tentatively at first but then with increasing speed vigour & confidence The overlaps & interdependence of the sciences the emerging order that they are gradually uncovering is without question the most enthralling aspect of twenty-first-century science
