Without the free field E 0 (t) in this equation the operator x(t) would be exponentially dampened, and commutators like [z(t),p z (t)] would approach zero for t ≫ 1 / τω 2 0 . With the vacuum field included, however, the commutator is iħ at all times, as required by unitarity, and as we have just shown. A similar result is easily ...

The value of a physical quantity Z is expressed as the product of a numerical value {Z} (a pure number) and a unit [Z]: = {} [] For example, let be "2 metres"; then, {} = is the numerical value and [] = is the unit. Conversely, the numerical value expressed in an arbitrary unit can be obtained as:
On 7 April 2018, economics teacher Rakesh Kumar and two other employees of a private school in Una, Himachal Pradesh were arrested for leaking the Class 12 economics paper. [39] According to the police, Rakesh Kumar had gone inside the strong room of a bank to pick up packets of computer science question papers but also picked up a packet of ...
