Tobias Hürter's 'The Age of Ambiguity' delves into the pivotal fifty years of physics from 1895 to 1945, a period marked by revolutionary discoveries and profound ethical dilemmas. This book uncovers the brilliant insights of scientific giants like Einstein, Planck, and Schrödinger, who fundamentally reshaped our understanding of the universe with quantum mechanics and relativity. Simultaneously, it explores the darker facets, including the scientific community's entanglement with two world wars and the devastating development of the atomic bomb. Hürter masterfully narrates how this era, initially bright with intellectual promise, became shrouded in moral complexity and ambiguity, forever altering the course of science and human history. It's a compelling exploration of innovation, conflict, and responsibility.
