A temporal paradox, time paradox, or time travel paradox, is a paradox, an apparent contradiction, ...
Time dilation by the Lorentz factor was predicted by several authors at the turn of the 20th century. [3] [4] Joseph Larmor (1897) wrote that, at least for those orbiting a nucleus, individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio: .

Temporal hours were common in many cultures. A division of day and night into twelve hours each was first recorded in Ancient Egypt.A similar division of day and night was later made in the Mediterranean basin from about Classical Greek Antiquity into twelve temporal hours each (Ancient Greek: ὥραι καιρικαί, romanized: horai kairikai).
Often there is a trade-off between the temporal resolution of a measurement and its spatial resolution, due to Heisenberg's uncertainty principle.In some contexts, such as particle physics, this trade-off can be attributed to the finite speed of light and the fact that it takes a certain period of time for the photons carrying information to reach the observer.
The B-theory of time, also called the "tenseless theory of time", is one of two positions regarding the temporal ordering of events in the philosophy of time.B-theorists argue that the flow of time is only a subjective illusion of human consciousness, that the past, present, and future are equally real, and that time is tenseless: temporal becoming is not an objective feature of reality.
Temporal, or time, deixis is used to refer to time relevant to the utterance. This includes temporal adverbs (e.g. then and soon), nouns (e.g. tomorrow) and use of grammatical tense. [17] Temporal deixis can be relative to the time when an utterance is made (the speaker’s "now") or the time when the utterance is heard or seen (the addressee ...
Temporal parts have properties, and have a temporal location. So if person A changes from having long hair to having short hair, then that can be paraphrased by saying that there is a temporal part of A that has long hair simpliciter and another that has short hair simpliciter , and the latter is after the former in the temporal sequence; that ...
The natural units for timekeeping used by most historical societies are the day, the solar year and the lunation.Such calendars include the Sumerian, Egyptian, Chinese, Babylonian, ancient Athenian, Buddhist, Hindu, Islamic, Icelandic, Mayan, and French Republican calendars.
