I still find it astonishing how good of an abstraction Matrices are for representing physical data. In CS terms, the use of matrix notation has allowed the description of complex multidimensional systems to be scalable. i.e. instead of adding an entry to the equation for every equation, you represent ALL the variables in a matrix and change that one matrix instead. So, this way of representation allows one to observe the relationships between these numbers better.

Little wonder that beginner physicists spend so much time mastering matrices and linear algebra.
