Idea Sparks explores the fascinating origins of revolutionary ideas across science and philosophy, revealing the hidden catalysts behind human innovation. It argues that groundbreaking concepts rarely emerge in isolation but often arise from unexpected connections, chance encounters, or reinterpretations of existing knowledge. The book emphasizes that innovation isn't solely the domain of genius; instead, it is a process that can be cultivated through specific practices. For example, the development of calculus or the theory of evolution illustrate how breakthroughs frequently stem from unique combinations of prior knowledge and circumstance. This book demystifies the creative process by examining the cognitive processes, such as lateral and divergent thinking, and the historical contexts where breakthrough ideas emerged. Structured in three parts, the book begins by introducing core concepts of creativity, then explores historical case studies, and culminates by synthesizing findings into actionable strategies for fostering innovation. By delving into primary sources like scientific papers and personal correspondence, Idea Sparks uncovers the often-overlooked, messy details behind major advancements.
