21

23

An imaginary number is a complex number (as 2 + 3i) in which the coefficient of the imaginary unit is not zero; a pure imaginary is a complex number that is the product of a real number other than zero and the imaginary

24

28

Anything which is experienced or perceived as existing, but which may not have a direct counterpart at the physical level A well-known technical example with practical applications in physical technologies is i, the square-root of -1 It is misleading and sometimes dangerous to regard 'real' and 'imaginary' as opposites: imaginary entities are real at the respective level of reality, and may have strong echoes in physical reality - as seen in the fact that 'imaginary' fears can sometimes be fatal It should also be noted that every product of a physical technology starts off as an imaginary entity - usually a mental image such as a design or conceptual model which is 'real-ised' through many different physical and other activities

29

Used here in its literal sense of 'image-inary', or to indicate something existing in personal or subjective reality and not yet carried through into objective reality (or cannot be expressed in terms of ordinary reality, as in 'imaginary numbers' in mathematics)
