Why do particle physicists like spending time in fields?

The concept of a field plays a key role in particle physics, but what exactly is it? From its origins in the study of magnetism to the quantum fields of today, columnist Chanda Prescod-Weinstein goes exploring

This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA?s Solar Dynamics Observatory. The complex overlay of lines can teach scientists about the ways the sun's magnetism changes in response to the constant movement on and inside the sun.
