Hungarian scientist Loránd Eötvös (Baron von Eötvös, Roland) is remembered today for his work on gravity and surface tension. The Eötvös Torsion Balance ("The Eötvös Torsion Balance") The Eötvös parameter (ie the change of the gravitational and inertial masses), the Eötvös effect (ie the change) The Eötvös physical unit (unit of acceleration divided by distance in distance), the Eötvös physical unit the centimeter-gram-second system of units, the Eötvös Loránd University, the Lor Eötvös Mathematics Competition, the Eötvös peak in the Dolomites, the mineral lorándite, and the Eötvös crater on the moon are named after him.

One of his main achievements is the Eötvös pendulum, which is a sensitive instrument for measuring the density of underlying rock strata. In the horizontal plane of the gravity of gravity. It determines the distribution of the masses in the Earth's crust. The Eötvös torsion balance, an important instrument of geodesy and geophysics throughout the world. It is used for mine exploration, and as well as for oil, coal and ores. The Eötvös pendulum was never patented, Hungary, abroad, and several other countries were discovered by using it. The Eötvös pendulum was used for the equivalence of the inertial mass and the gravitational mass accurately. This equivalence was used later in the theory of general relativity.
