TPMS have been observed as biological membranes, as block copolymers, equipotential surfaces in crystals etc . They have also been of interest in architecture, design and art.

Since the Sea Level Datum of 1929 was a hybrid model, it was not a pure model of mean sea level, the geoid, or any other equipotential surface.
23.
In a state of rest or absence of external forces, the mean sea level would coincide with this geoid surface, being an equipotential surface of the Earth's gravitational field.
24.
The formulas for calculating the normal gravity is based on the assumption of an imagined rotationally symmetrical ellipsoid model of the earth, the surface of which is identical to an equipotential surface.
25.
In electrostatics, the work done to move a charge from any point on the equipotential surface to any other point on the equipotential surface is zero since they are at the same potential.
26.
In electrostatics, the work done to move a charge from any point on the equipotential surface to any other point on the equipotential surface is zero since they are at the same potential.
27.
Taylor's derivation is based on two assumptions : ( 1 ) that the surface of the cone is an equipotential surface and ( 2 ) that the cone exists in a steady state equilibrium.
28.
Additional tidal bench mark elevations were not used due to the demonstrated variations in sea surface topography, i . e ., that mean sea level is not the same equipotential surface at all tidal bench marks.
29.
A geopotential field U is constructed, being the sum of a gravitational potential \ Psi and the known centrifugal potential \ Phi, that " has the GRS80 reference ellipsoid as one of its equipotential surfaces ".
30.
In 2001, Mars Orbiter Laser Altimeter data led to a new convention of zero elevation defined as the equipotential surface ( gravitational plus rotational ) whose average value at the equator is equal to the mean radius of the planet.
