cârcub-e bâzbord-e laxtinâk, ~ ~ laxtimand
Fr.: référentiel galiléen
A → reference frame or coordinate system in which there are no accelerations, only zero or uniform motion in a straight line. According to the special theory of relativity, it is impossible to distinguish between such frames by means of any internal measurement.
To like better or value more highly.
M.E. preferre, from O.Fr. preferer and directly from L. praeferre "to place or set before, carry in front," from prae "before," → pre-, + ferre "to carry, to bear," from PIE root *bher- "to carry;" cf. Pers. bordan "to carry, bear," → refer.

Tâti zun/zund "to know," Khunsâri zûn-/zûnâ, Mahallâti zôn-, Semnâni -zûn-, Hamedâni zunayän/zun- , Esfahâni zunän/zun-, Yarandi zônâj-/zôn-, Gazi zûn-/zûnâšt; Av. zān- "to know," → science.

Fr.: ellipsoïde de référence
A mathematically defined surface that approximates the Earth's shape, which is basically a sphere "flattened" at its poles. The length of one of the axes at the Equator is chosen so that the ellipsoid coincides at this latitude with the mean sea level. It is the first-order definition of the non-spherical shape of the Earth as an ellipsoid of revolution. To first order, it accounts for over 90% of the → geoid.
Fr.: système de référence
A set of axes to which positions and motions in a system can be referred. Same as → frame of reference.
Fr.: source de référence
An astronomical source in a field used as a reference for the detection of another object, astrometry, etc.
