A long overdue distinction between so-called variant and invariant complex potentials is proposed here for the first time. Invariant complex potentials describe physical flows where a switch of the real and imaginary parts of the function will still describe the same type of physical flow (but only rotated by π/2). Such invariants can be formulated with Euler’s formula to d... https://www.roneverhart.com/Apple-Watch-Series-6-GPS-Cellular-40mm-Silver-Aluminum-w-White-Sport-Band/
