Each moment events take place that the human eye cannot perceive because these occurrences are too small, too large, too fast, too slow, or beyond the spectrum of visible light. Entire worlds might escape our inspection if it were not for some extraordinary photographic techniques, sophisticated cameras, and imaging devices. The Invisible World will captivate you with the sight of water crystallizing into ice; a single atom's movement within solid matter; a bullet speeding towards its target—and will forever alter your understanding and perception of the world.
