Gravitational Wave Energy Calculation Corrected
Einstein revisited his gravitational-wave analysis and corrected the treatment of radiated energy, removing misleading wave modes from the earlier calculation.
Albert Einstein · Year
1918
Albert Einstein records dated 1918, drawn directly from the World History Database source collection.
Mach Principle Formulation
Publishes a foundational discussion of general relativity in which he explicitly names Mach's principle and distinguishes it from the equivalence and relativity principles.
Mass Quadrupole Identified as Leading Radiation Source
Einstein showed that the leading gravitational radiation from an isolated slow-moving system is governed by changes in its mass quadrupole moment rather than by a simple mass dipole.
Quadrupole Formula for Gravitational Waves
Refines gravitational-wave theory and derives the quadrupole form for radiated energy.
Quadrupole Radiation Formula
Derives the quadrupole formula for gravitational radiation, relating emitted wave power to changing mass distributions in accelerating systems.
Zurich Guest Lectures
Returns to Zurich for guest lectures while continuing work on relativity and quantum theory.
