Schr\"{o}dinger's Magnetic Ambitions: His Attempts in the 1940s to Understand Terrestrial Magnetism through a Unitary Field Theory.

In 1943, Schr\"{o}dinger presented several papers to the Royal Irish Academy outlining his efforts to unify electromagnetism, gravitation, and what is now known as the strong force in a Unitary Field Theory. To furnish experimental proof for his ideas, he suggested that variations in Earth's magnetic field might be understood through his theoretical notion that electromagnetism is attenuated by a kind of cosmological constant. We'll explore the nature and context of his proposal and examine reactions to his assertions.
