It also gives rise to the mysterious Casimir force, also called van der Waals forces, that keeps geckos stuck to any surface. Most importantly, it also causes nonthermal noise in lots of electronic circuits which this author claims can be rectified by special diodes that have no bias voltage to surmount. Zero point energy is also becoming the leading candidate for dark energy. The book is full of pictures, like all of the famous...
