Your entry Graveure, Louis, 1888-1965 would be here
Graveyards -- See Cemeteries Here are entered general works on cemeteries and burying-grounds. Works on tombs and mausoleums, mainly from the archaeological standpoint, are entered under Tombs. Works on funerary monuments and gravestones are entered under Sepulchral monuments.
Gravitational radiation -- See Gravitational waves Here are entered works on hypothetical waves predicted by the general theory of relativity that are created by disturbances of matter and travel through space at the speed of light propagating gravitational fields. Works on waves in a fluid medium that are generated by the force of gravity, such as those between air and water at an ocean's surface or between layers of air in the Earth's atmosphere, are entered under Gravity waves.
Gravity-free state, Physiological effect of -- See Weightlessness Here are entered works on the physiological and psychological effects of environments in which the gravitational forces are zero or markedly lower than the gravity on earth.Works on the physiological effects of normal gravity and of acceleration expressed in g's are entered under Gravity--Physiological effect.Works on the physics or theory of gravitational forces are entered under Gravitation or Gravity.
Gravity waves (Astrophysics) -- See Gravitational waves Here are entered works on hypothetical waves predicted by the general theory of relativity that are created by disturbances of matter and travel through space at the speed of light propagating gravitational fields. Works on waves in a fluid medium that are generated by the force of gravity, such as those between air and water at an ocean's surface or between layers of air in the Earth's atmosphere, are entered under Gravity waves.
