Affine Field Theory
Explores an affine field theory as a possible extension of general relativity, seeking a unified geometric description of gravitation and electromagnetism.

1923
Albert Einstein records dated 1923, drawn directly from the World History Database source collection.
Compton Scattering Strengthens Light-Quantum Momentum Picture
The emerging evidence from Compton scattering gave strong experimental support to the energy-and-momentum properties of radiation quanta that Einstein had advocated for years.
General Relativity Academy Paper
Publishes a further Prussian Academy paper on general relativity, revisiting technical aspects of the theory after its rapid international acceptance.
Leiden Research Stay
Spends an extended period in Leiden amid political threats in Germany, continuing scientific work.
Photon Momentum Evidence Reinforces Einstein Radiation Theory
Experimental scattering results increasingly supported the view that individual radiation quanta carry directed momentum, a requirement already embedded in Einstein's 1917 radiation theory.
