"Electrons Don’t Think"? (response to Sabine Hossenfelder)

In 'Lost in Math', Sabine Hossenfelder critiques the dominance of the concept of 'beauty' in theoretical particle physics. She argues that the emphasis on mathematical elegance and symmetry has hindered progress in the field, leading to untestable theories such as string theory and supersymmetry. Through interviews with prominent physicists and detailed analysis, Hossenfelder highlights the problems with current approaches and suggests that a more pragmatic and evidence-based approach is needed. The book also explores historical examples where 'beautiful' theories were initially rejected but later proven correct, and it questions the anthropic arguments that some physicists use to justify untestable theories.

In this book, Carlo Rovelli delves into the mysteries of time, combining physics, philosophy, and art to explain how modern physics has transformed our understanding of time. The book is divided into sections that cover the theory of relativity, space-time, loop quantum gravity, and thermodynamics. Rovelli argues that at the most fundamental level, time disappears, and our perception of its flow is subjective and influenced by our brain and emotions. He uses metaphors and simple language to make complex concepts accessible to a broad audience.
