Select Source

Gin and tonic was invented to combat malaria in British colonies like Java, which leads us to Geneva, where cleanliness is an obsession. Here, tonic water was sealed with a disposable bottle cap, and razors became disposable, leading us to Huntsman's steel, invaluable for making clock springs. We take a little trip through lighthouses, the education of orphans, psycho-physics, the law of the just noticeable difference, which is the idea behind stellar magnitudes, which leads us to discovering the size of the universe.
