·noun A geodetic line or curve.

Geodesic curvature         
In Riemannian geometry, the geodesic curvature k_g of a curve \gamma measures how far the curve is from being a geodesic. For example, for 1D curves on a 2D surface embedded in 3D space, it is the curvature of the curve projected onto the surface's tangent plane.
Schwarzschild geodesics         
  • Bending of waves in a gravitational field. Due to gravity, time passes more slowly at the bottom than at the top, causing the wave-fronts (shown in black) to gradually bend downwards. The green arrow shows the direction of the apparent "gravitational attraction".
  • Diagram of gravitational lensing by a compact body
  • Comparison between the orbit of a test particle in Newtonian (left) and Schwarzschild (right) spacetime; note the [[apsidal precession]] on the right.
  • Mercury]], [[Venus]] and Earth.  The yellow dot within the orbits represents the center of attraction, such as the [[Sun]].
  • The stable and unstable radii are plotted versus the normalized angular momentum <math display="inline">\frac{a}{r_\text{s}} = \frac{L}{mcr_\text{s}}</math> in blue and red, respectively.  These curves meet at a unique circular orbit (green circle) when the normalized angular momentum equals the square root of three.  For comparison, the classical radius predicted from the [[centripetal acceleration]] and Newton's law of gravity is plotted in black.
  • Effective radial potential for various angular momenta. At small radii, the energy drops precipitously, causing the particle to be pulled inexorably inwards to <math display="inline">r = 0</math>. However, when the normalized angular momentum <math display="inline">\frac{a}{r_\text{s}} = \frac{L}{mcr_\text{s}}</math> equals the square root of three, a metastable circular orbit is possible at the radius highlighted with a green circle. At higher angular momenta, there is a significant centrifugal barrier (orange curve) and an unstable inner radius, highlighted in red.
In general relativity, Schwarzschild geodesics describe the motion of test particles in the gravitational field of a central fixed mass M, that is, motion in the Schwarzschild metric. Schwarzschild geodesics have been pivotal in the validation of Einstein's theory of general relativity.
Geodesic convexity         
NATURAL GENERALIZATION OF CONVEXITY FOR SETS AND FUNCTIONS TO RIEMANNIAN MANIFOLDS
Geodesic convex; Geodesically convex
In mathematics — specifically, in Riemannian geometry — geodesic convexity is a natural generalization of convexity for sets and functions to Riemannian manifolds. It is common to drop the prefix "geodesic" and refer simply to "convexity" of a set or function.
Geodesic polyarene         
  • Crystal structure of pentaindenocorannulene.
  • Pentaindenocorannulene X-ray crystal structure depiction
  • Synthesis of C50H10
  • Synthesis of Pentaindenocorannulene
A geodesic polyarene in organic chemistry is a polycyclic aromatic hydrocarbon with curved [ or concave] surfaces.Geodesic polyarenes with exposed concave surfaces Lawrence T.
Geodesic map         
DIFFEOMORPHISM THAT PRESERVES GEODESICS
Geodesic function; Geodesic mapping; Geodesic diffeomorphism; Geodesic Mapping
In mathematics—specifically, in differential geometry—a geodesic map (or geodesic mapping or geodesic diffeomorphism) is a function that "preserves geodesics". More precisely, given two (pseudo-)Riemannian manifolds (M, g) and (N, h), a function φ : M → N is said to be a geodesic map if
Geodesic deviation         
In general relativity, put another way, if two objects are set in motion along two initially parallel trajectories, the presence of a tidal gravitational force will cause the trajectories to bend towards or away from each other, producing a relative acceleration between the objects.
Geodesic dome         
  • Buckminster Fuller's own home]], undergoing restoration after deterioration.
  • The Climatron]] greenhouse at [[Missouri Botanical Gardens]], built in 1960 and designed by Thomas C. Howard of Synergetics, Inc., inspired the domes in the science fiction movie ''[[Silent Running]]''.
  • Spaceship Earth]] at [[Epcot]]
  • Long Island Green Dome
  • Science World]] in Vancouver, built for [[Expo 86]], and inspired by [[Buckminster Fuller]]'s Geodesic dome.

Geodesic structures; Triangular element; Geodesic domes; Buckminster Fuller dome; Geodome; Geodisic dome; Geodesic Dome; Geodesic ball; Geodesic dome home; Dome Home; Dome home
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size.
