Origin of nonlinearity¹

First recorded in 1925–30; non- + linearity

Example Sentences

"Nonlinearity in optics is quite challenging because photons don't interact with each other very easily. That makes it very power consuming to trigger optical nonlinearities, so it becomes challenging to build a system that can do it in a scalable way," Bandyopadhyay explains.
