. The Sun's velocity is about 250 km/s or 560,000 mph.
Every source emits particles isotropically in the source rest frame
. The observed [eta] mesons are from different emission sources.
at an oblique line in the space-ct diagram), creates the difference in perceived length between a body in its rest frame
and a frame in movement, as seen in Fig.
The Mantis was designed with a heavy-duty, aluminium-alloy mounting bracket and rest frame
with a vibrant green Delrin arrow-capture gate and arrow launch pad that ensures a smooth launch of the arrow while preventing wear on the rest.
in [the test particle's] instantaneous rest frame
, the remainder of the universe appears as an enveloping accelerated body." (8)
In his first derivation of the conversion of entropy and temperature in 1907, Einstein noted that the pressure and volume in the rest frame
comoving with the object (denoted by subscript o) and those in the stationary frame satisfy
Hereinafter the subscript "0" denotes the given quantity defined in the rest frame
According to the book, our knowledge of motion is remote because--to cite one central reason given--absolute motion is incoherent, and in cases of relative motion what moves cannot be determined: "a fly buzzing about the room is no more absolutely in motion than the whole galaxy is--we can in principle select the fly as our point of reference ('rest frame
') and conceive everything else as moving relative to it." Why the book's central criteria for theory selection--"explanatory power and internal coherence"--do not exclude the fly-as-stationary hypothesis from serious consideration is not clear.
* Programmable rest frame
periods/ response-times and downshift times from one power-saving mode to another.
Each object when considered in its own rest frame
has definitive rest mass and rest length, which can be considered to be characteristic of the object.
The unique Air-Rest EXT relies on a set of magnets built into the rest frame
to suspend the arrow at full draw, which means the shaft touches nothing from the moment of suspension through the release.
