Definition
Meaning and Definition
A precise scientific instrument for measuring gravitational gradients and horizontal variations in the Earth's gravitational field.
A highly sensitive device used in geophysics and fundamental physics experiments to measure minute gravitational effects, named after its inventor Baron Loránd Eötvös. It is especially known for testing the equivalence principle of gravitational and inertial mass.
Dialectal Variation
British vs American Usage
Differences
No significant differences in usage or spelling, though British English is more likely to retain the diaeresis (Eötvös). American English often simplifies it to 'Eotvos'.
Connotations
Identical scientific connotations in both varieties.
Frequency
Extremely rare in general discourse; used exclusively in geophysics, geology, metrology, and fundamental physics contexts.

FAQ
Frequently Asked Questions
It was invented by the Hungarian physicist Baron Loránd Eötvös in the late 19th century.
It provided a highly precise test of the equivalence principle, which states that gravitational mass and inertial mass are equivalent.
While modern, automated gravimeters and gradiometers are now standard, the principles of the Eötvös design remain foundational, and modern equivalents are used in space missions and geophysical prospecting.
It refers to the twisting force (torque) applied to a thin fibre or wire from which the balance's beam is suspended, which is used to measure the minute gravitational forces.
A precise scientific instrument for measuring gravitational gradients and horizontal variations in the Earth's gravitational field.
