Albert Einstein · Year
Albert Einstein records dated 1925, drawn directly from the World History Database source collection.
Einstein continued to favour exact energy and momentum conservation in individual radiation processes rather than the merely statistical conservation proposed by the Bohr-Kramers-Slater approach.
Einstein drew an analogy between the wave-particle duality he had identified for radiation and the emerging wave description of material particles, reinforcing the broader quantum duality concept.
Joins the administrative council of the Hebrew University of Jerusalem.
Engages critically with the emerging matrix and wave formulations of quantum mechanics.
Publishes further work on the quantum theory of the ideal monatomic gas.
Tours Argentina, Uruguay and Brazil, giving lectures and meeting scientific and civic audiences.
Publishes a unified field theory of gravitation and electricity, beginning a long programme to extend relativity into a single classical field framework.
Lectures in Buenos Aires on relativity and modern theoretical physics, bringing his account of spacetime and gravitation to large South American audiences.
Visits Montevideo and discusses relativity with university and public audiences, extending the international circulation of his gravitational and spacetime ideas.
Speaks in Rio de Janeiro during his South American tour, explaining relativity while participating in debates about theoretical science and its wider significance.
Awarded the Royal Society's Copley Medal for relativity and contributions to quantum theory.
