WitrynaFrom a modern physics viewpoint, time is not a vector nor a scalar, it is a coordinate. This is because time is relative depending on the observer, so it cannot be defined as a scalar or a vector. In Newtonian physics, however, time has a universal meaning and is usually thought of as a scalar. WitrynaAnswer: Suppose I ask a question "What is the temperature at the tip of my nose?"
