Einstein-Szilard Refrigerator Patent
Patent work with Leo Szilard advances an absorption refrigerator using electromagnetic pumping concepts.
Teleparallel Unified Field Programme
Develops the teleparallel unified-field programme, replacing ordinary Riemannian geometry with tetrad-based structures intended to encompass gravitation and electromagnetism together.
Teleparallel Unified Field Theory
Develops a unified-field approach using distant parallelism, also called teleparallel geometry.
Tetrad Fields Introduced for Unified Gravitation
Einstein adopted tetrad fields and distant parallelism as a new geometric language in an attempt to place gravitation and electromagnetism inside one unified classical field theory.
