The phrase "a direction of time" is correct and usable in written English.
It can be used when discussing concepts related to time, such as in physics, philosophy, or when describing a sequence of events.
Example: "In the study of relativity, we often consider a direction of time as a fundamental aspect of the universe."
Alternatives: "a temporal direction" or "a time orientation".
If so, these will be reversible, like the graph of Figure 13, and will give no indication of a direction of time.
The third argument intends to produce a direction of time from causal directions inferred from macrostatistics.
This places the root of all HMG domains within the HMGB group and allows us to map a direction of time onto the phylogram.
With these ideas in mind, we provide a "transcriptomic-driven" method revealing important biomarkers for cancer progression a direction of time for which they are presented.
Because the field equations of general relativity do not pick out a preferred direction of time, if the formation of a black hole is allowed by the laws of spacetime and gravity, then white holes will also be permitted by these laws.
But the equations of thermodynamics, which describe the collective random motion of many trillions of particles, do contain a definite direction of time.
Thus the now contains new contents and fading, older contents; and a natural direction of time.
Studios and network executive are risk averse, and prequels, which can stretch a franchise in the opposite direction of time, provide a slightly more imaginative way of cashing in on success than remakes.
a A large arrow indicates the direction of time from the past to the present.
Similarly the entropic theorist claims that it is the entropic features that explain the intuitive asymmetries noted above, that in regions of the universe in which the entropic asymmetry was counter-directed in time the past-future directions of time would be opposite, and that in a region of the universe without an entropic asymmetry neither direction of time would count as past or as future.
So the theory does not suffer from a problem of the direction of time as stated above.
