number plate

Identifying plates fitted to vehicles in the UK (and elsewhere), carrying the vehicle's registration number.
Similar to License plate, Registration plate etc.

In the UK the reg. no. belongs to the vehicle, not the driver, and contains information about the age of the vehicle and the region in which it was first sold. The system is administered by the DVLA.

The reg. number is alphanumeric, and takes the form AB12 CDE on vehicles registered after 2001, or A123 BCD on vehicles registered before 2001.

Some scouse git has stolen my number plates. Now I will be done by the police.

jimaginary number

A portmanteau of "j" and "imaginary" for the imaginary component of a complex number. This means the same thing as Imaginary Number, and typically this number would have an italicized i after it. In electrical engineering, the letter "i" has other and more apparent meanings, so to avoid confusion we pick the next letter, j.

Compare imaginary with jimaginary number
Sheldon would use 1 + 2i.
Howard would use 1 + 2j.
