spacetime coordinates造句

• The Euler Lagrange equations in the spacetime coordinates are
• The past travels away from this spacetime coordinate at a rate equal to the speed of light.
• The transformation matrix is universal for all four-vectors, not just 4-dimensional spacetime coordinates.
• N and N ^ i are functions of spacetime coordinates and can be chosen arbitrarily in each point.
• This parameter is promoted to a field, i . e . to a function of the spacetime coordinates.
• Where are the spacetime coordinates used to define events in one frame, and are the coordinates in another frame.
• The Daleks command that once the spacetime coordinates of the box are confirmed, whoever is using that device must be exterminated.
• In the theory of relativity, it is convenient to express results in terms of a spacetime coordinate system relative to an implied spatial coordinates.
• It says that the dynamical equations of the gravitational field and any matter must be unchanged in form under any smooth transformation of spacetime coordinates.
• We can completely specify an event by its four spacetime coordinates : The time of occurrence and its 3-dimensional spatial location define a reference point.
• The spacetime coordinates of an event, as measured by each observer in their inertial reference frame ( in standard configuration ) are shown in the speech bubbles.
• One can understand 2 of the 12-dimensions of F-theory as a bookkeeping device; they should not be confused with the other 10 spacetime coordinates.
• At an instant of lab-recorded time measured in the lab frame, the transformation of spacetime coordinates from the lab frame to the particle's frame ? is
• A global symmetry is the symmetry which remains invariant at each point of a manifold ( manifold can be either of spacetime coordinates or that of internal quantum numbers ).
• General relativity being a prime physical example ( here the spacetime coordinates correspond to the unphysical \ tau and the Hamiltonian is a linear combination of constraints which generate spatial and time diffeomorphisms ).
• Exponentiating the generators gives the boost and rotation operators which combine into the general Lorentz transformation, under which the spacetime coordinates transform from one rest frame to another boosted and / or rotating frame.
• Neither local R4 spacetime coordinates for one of many possible C3 subspaces are sufficient to explain them, nor an infinite dimensional Hilbert space of QM . The old theories need a revision on the grounds of modern findings.
• When a light signal exchange procedure is used to infer spacetime coordinates of distant events from the travel time of photons, information about the photon's energy is discarded with the assumption that the frequency of light doesn't matter.
• If the four spacetime coordinates " x " ?are given in arbitrary units ( i . e . unitless ), then " g " 到 in m 2 is the rank 2 symmetric metric tensor which is also the gravitational potential.
• Given the strong resemblance to rotations of spatial coordinates in 3d space in the Cartesian xy, yz, and zx planes, a Lorentz boost can be thought of as a hyperbolic rotation of spacetime coordinates in the xt, yt, and zt Cartesian-time planes of 4d Minkowski space.
