The Evolution of Physics
The year was 1938 when Albert Einstein and Leopold Infeld sat down to write a book about physics. Their partnership began not from shared academic ambition but from financial necessity. Infeld had moved to Princeton to work with Einstein at the Institute for Advanced Study after a brief collaboration in Cambridge with Max Born. Einstein tried hard to secure a permanent position for his colleague there, but he failed. Infeld needed money and devised a plan to co-author a history of physics that would surely succeed. He approached Einstein with this proposal while becoming incredibly tongue-tied during the pitch. The physicist listened intently before responding with clear approval. This is not at all a stupid idea, Einstein said. Not stupid at all. We shall do it. They split the royalties from the project. Simon & Schuster published the book in the United States later that same year.
Albert Einstein pushed his realist approach to physics throughout the text despite growing opposition from quantum mechanics. The authors argued that belief in an objective reality had driven great scientific advances across centuries. They claimed this concept remained useful even if it could not be proven mathematically. Without the belief that it is possible to grasp reality with our theoretical constructions, they wrote, there could be no science. This belief remains the fundamental motive for all scientific creation according to their conclusion. Einstein used the book to defend field theories against emerging quantum ideas. He suggested viewing particles as special manifestations of the field itself rather than independent objects. Could we not reject the concept of matter and build a pure field physics? he asked. A thrown stone becomes a changing field where states of greatest intensity travel through space with the velocity of the stone. This perspective allowed him to maintain faith in physical laws while acknowledging experimental results.
Science resembles a detective story when examining nature's clues, the authors stated early in Chapter One. Investigators must collect unordered facts and make them coherent through creative thought without turning to the end of the book first. Galileo's law of inertia served as the initial clue codified by Isaac Newton. Every body perseveres in its state of rest or uniform motion unless compelled to change by forces impressed therein. Later chapters explored investigations into electricity conducted by Charles Augustin de Coulomb, Luigi Galvani, Alessandro Volta, and Hans Christian Ørsted. Newton proposed corpuscular theory regarding light while Christiaan Huygens argued for wave theory instead. A Socratic dialogue between supporters of each view highlighted the conflict. Scientists believed light required a medium called luminiferous aether to travel through space. Attempts to detect this medium yielded null results despite extensive searching. The authors concluded that no hope existed for reducing optical phenomena to mechanical ones before answering what medium carried light waves. These difficulties proved so great they had to abandon the mechanical view entirely.
Lines of force began with gravitational fields before expanding to electric and magnetic descriptions. Two pillars supported field theory: the change of an electric field accompanied a magnetic field. Interchanging words revealed symmetry since changing magnetic fields also coiled around changing electric fields. Oersted demonstrated how magnetic fields formed coils around changing electric currents. Faraday showed how changing electric fields created similar patterns around magnetic variations. James Clerk Maxwell explained these interactions through his field theory equations. Heinrich Hertz confirmed the existence of electromagnetic waves predicted by Maxwell's work. These waves traveled at the speed of light indicating light itself was an electromagnetic phenomenon. The Michelson, Morley experiment established that light speed remained constant regardless of observer motion. New assumptions led to special relativity stating velocity in vacuo stayed identical across all coordinate systems moving uniformly relative to one another. All laws of nature remained consistent within those same frames. Mass-energy equivalence emerged from these principles alongside discussions of general relativity. Thought experiments involving free-falling elevators and rotating discs illustrated gravitational effects. Gravitational lensing bent light around massive bodies while explaining Mercury's perihelion precession mystery.
J.J. Thomson discovered the electron as quanta of electricity and constituent part of atoms. Max Planck introduced energy quanta concepts that reshaped understanding of atomic behavior. The photoelectric effect became explainable through light quanta or photons rather than continuous waves. Niels Bohr developed a model describing atomic structure with specific orbits for electrons. Erwin Schrödinger and Louis de Broglie proposed matter waves representing probabilistic quantum mechanics. Einstein maintained belief in objective reality despite experimental success of quantum theory. Throughout all our efforts, he wrote, we recognize eternal longing for understanding strengthened by obstacles to comprehension. The authors discussed how probability replaced certainty in modern physics explanations. They acknowledged dramatic struggles between old mechanical views and new quantum perspectives. Yet they insisted on maintaining faith in world harmony despite increasing comprehension barriers. This stance reflected their commitment to realism even when facing contradictory evidence from laboratory results.
The New York Times reviewed the book favorably noting remarkable simplicity and clarity without much literary art. Though no mathematical equation frightened readers who remembered only multiplication tables, poetic analogies remained absent compared to writings by Jeans and Eddington. Both those authors faced critical machine guns targeting God is a mathematician and mysticism respectively. This book testified Einstein remained clearest exploiter of his own theories according to reviewers. J.A. Crowther wrote in Nature that physics creation gave cultural significance through freely invented ideas. Intellectual content provided thoughtful non-technical readers main source of interest in distinguished work. Time magazine featured the book on its cover shortly after publication. Cambridge University Press released it originally while Simon & Schuster handled US distribution. Reviews appeared across multiple publications including The Boston Transcript, Manchester Guardian, and The Nation during spring 1938. Scientific Book Club Review praised accessibility while The Yale Review highlighted philosophical depth. The text achieved popular success beyond academic circles reaching general audiences eager for scientific understanding.
