In physics, tensors are often a mixture of several vector spaces and several dual spaces. It also makes sense to sort both kinds as the tensor product isn’t commutative. Type (p,q) Tensors Definition: A tensor of type of with contravariant and covariant components is an element (vector) of By (1) this tensor is linear in all its components.

All undergraduate physics majors are shown how the counterintuitive aspects (“mysteries”) of time dilation and length contraction in special relativity (SR) follow from the light postulate, i.e., that everyone measures the same value for the speed of light c, regardless of their motion relative to the source (see this Insight, for example).
Congratulations to the graduating class of Spring 2023. Physics will be celebrating our graduates on Friday, May 12th. Below are student profiles from this year's graduating class. I worked at Dr.
