  • 1785: Mathematician, philosopher, and phenomenological crime-fighter Thomas Reid publishes new theory of sensus communis) based on the belief that there is a Gnomon algorithm which accurately represents the external world. Reid's work will soon find applications in the detection and prevention of crimes against physical constants.
