Complex numbers: an introduction
We will leave the domain of real numbers behind us and start exploring the plane of complex numbers. An introduction to a realm beyond imagination.
Deriving the Lorentz transformations from a rotation of frames of reference about their origin with real time Wick-rotated to imaginary time
Well-known for their central role in Einstein’s Special Relativity, the Lorentz transformations are derived from the rotation of two frames of reference in standard configuration while time is taken to be an imaginary unit of spacetime. This is rarely seen in the wild. Not many undergraduate textbooks or online texts show the details of the working. Hence, this article.
