The New Accelerator Illustrated

The New Accelerator is a 1901 science fiction short story by H. G. Wells, first published in The Strand Magazine in December 1901. The story addresses an elixir, invented by a Prof. Gibberne, that accelerates all of an individual's physiological and cognitive processes by some orders of magnitude, such that although the individual perceives no change in themselves, the external world appears almost frozen into immobility and only the motion of most rapidly moving objects - such as the tip of a cracked whip - can be perceived.
