Minkowskian refers to the concepts or notions related to Minkowski space or geometry. However, there are several synonyms for the term, including Lorentzian, Pseudo-Euclidean, and Spacetime. Lorentzian refers to the theory of special relativity and is named after the Dutch physicist Hendrik Lorentz, who formulated the principle of length contraction. Pseudo-Euclidean is another synonym commonly used to describe Minkowski space, emphasizing that it is not a Euclidean space. Finally, spacetime refers to the four-dimensional continuum that encompasses the three dimensions of space and one dimension of time. It enables physicists and mathematicians to describe the universe's physical events and structures in a unified way.
