  2. Time-translation symmetry - Wikipedia

    en.wikipedia.org/wiki/Time-translation_symmetry

    Time-translation symmetry is the law that the laws of physics are unchanged (i.e. invariant) under such a transformation. Time-translation symmetry is a rigorous way to formulate the idea that the laws of physics are the same throughout history. Time-translation symmetry is closely connected, via Noether's theorem, to conservation of energy. [1]

    In the first mode, events are ordered as future, present, and past.Futurity and pastness allow of degrees, while the present does not. When we speak of time in this way, we are speaking in terms of a series of positions which run from the remote past through the recent past to the present, and from the present through the near future all the way to the remote future.

    In the International System of Units (SI), the unit of time is the second (symbol: s). It has been defined since 1967 as "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom", and is an SI base unit.

    The traditional origin is said to be a curse set upon the play by a coven of witches, angry at Shakespeare for using a real spell. [2] One hypothesis for the origin of this superstition is that Macbeth, being a popular play, was commonly put on by theatres in financial trouble, or that the high production costs of Macbeth put theatres in financial trouble.

    The time required for a quantity to fall to half its value as measured at the beginning of the time period. In physics, half-life typically refers to a property of radioactive decay, but may refer to any quantity which follows an exponential decay.
