Web3. We are currently covering special relativity in the theoretical physics lectures where we defined: d s 2 := d t 2 − d x 2 − d y 2 − d z 2. In Road to Reality, this is introduced using a metric tensor g μ ν which is d i a g ( 1, − 1, − 1, − 1). With a scalar product between two (four-row) vectors x and y. x, y := g μ ν x μ y ν.

The d’Alembertian is a linear second order differential operator, typically in four independent variables. The time-independent version (in three independent (space) variables is called the Laplacian operator. When its action on a function or vector vanishes, the resulting equation is called the wave equation (or Laplace’s equation). craftsman keychain remote https://pittsburgh-massage.com
