The imaginary unit in algebra with respect to quadratic field extensions?

Byursula44549

The question is whether i = sqrt(-1)? We consider the polynomial x^2 + 1 in R[x], or the quadratic equation x^2 + 1 = 0. This has a discriminant of -1 according to the quadratic solution formula. Since the discriminant in R is not a square, the equation in R is unsolvable. We adjoint the…

It is said that there are four dimensions, three spatial dimensions, and then time. When asked about possible additional dimensions, the question and the answers almost always only concern additional spatial dimensions. Now I would like to ask if you believe there are additional time dimensions. Feel free to write what you imagine these to…
