If you say so. But I'll leave you to correct all the sources which talk
about the way imaginary numbers extend the system of real numbers to
give the complex number system. I was never more than a wannabe
practical physicist so I've always deferred to mathematicians when it
come to things like that.
The idea is that complex numbers are essentially two dimensional whereas
ordinary numbers are not.
So they can represent things that have orthogonal components, like
amplitude and phase in voltages/currents etc.
the biggest threat to humanity comes from socialism, which has utterly
diverted our attention away from what really matters to our existential
Thanks for that, although believe it or not, I do still recall a *few*
things from O-level. That said, the use of complex numbers for
probability amplitudes is about all I can now recall from Rudolf
Peierls' lectures on quantum electrodynamics :(
Indeed - partly a result of the early discoverers of them not really
understanding that complex numbers were "real" and not just a
mathematical slight of hand.
I find it easier to think of in two dimensions, where the real number
line, is just a straight line where there is 0 deviation into the
I was puzzled what the conundrum was supposed to be, too.

straight away. I was hoping for a lengthy, argumentative thread on this!"
