The Evolution of Physics

Co-authored by Albert Einstein and Leopold Infeld, *The Evolution of Physics* takes readers on a captivating, accessible journey through the most transformative shifts in physical thought. Starting with Aristotle’s intuitive, long-dominant views on motion, it traces how Galileo’s experimental rigor laid the groundwork for Newton’s classical mechanics—establishing laws that governed our understanding of the macro world for centuries. The book then explores the cracks in this "mechanical view": the rise of thermodynamics and electromagnetic theory, which challenged the idea that all phenomena could be reduced to particle interactions. It delves into the revolutionary concepts of fields, Einstein’s special and general relativity (redefining space, time, and gravity as curved spacetime), and the birth of quantum mechanics, which upended deterministic views with wave-particle duality and probability waves. More than a textbook, it focuses on the evolution of ideas, making complex physics approachable for anyone curious about how we’ve unlocked the universe’s secrets.

Spacetime Curvature

Mass/energy warps spacetime. Objects move along these curved paths—this is gravity, not a 'pulling force'.
