Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
The production of a potential difference across an electrical conductor when a magnetic field is applied in a direction perpendicular to that of the flow of current.
- ‘The resistivity, which is the inverse of the conductance, in the Hall effect varies linearly with the applied magnetic field.’
- ‘There's also the fractional quantum Hall effect: electrons trapped between two semiconductor surfaces can appear as quasi-particles with charges less than those of single electrons.’
- ‘In a normal Hall effect, a voltage is created perpendicular to an electric current as it flows through a conductor in a magnetic field.’
- ‘While lasers were being fabricated for optical communications, basic research in III-V semiconductors led to the discovery of the fractional quantum Hall effect by Horst Störmer and Daniel Tsui.’
- ‘The work has been made possible through the Caltech team's earlier discovery of a phenomenon dubbed the ‘giant planar Hall effect.’’
Early 20th century: named after Edwin H. Hall (1855–1938), American physicist.
