Physics with Nabla T-shirt

The upside down triangle you often see in physics is called nabla.  We often read it as “del”, because it looks like an upside down capital delta.

The symbol doesn’t usually show up in introductory physics classes until Maxwell’s Equations are introduced in Physics II during the unit on electromagnetic waves.

Physics majors, however, become very familiar with the symbol when they start to learn vector calculus.  Here it shows up in several important situations, including the gradient, the divergence, and the curl.
