September 9, 2008 “Eureka” (Greek for "I have found it") is an exclamation used as an interjection to proclaim an epiphanic discovery. Famously pronounced in the bathtub by Archimedes when he suddenly understood that the volume of irregular objects could be calculated with precision through the displacement of water, a previously intractable problem. Real-world problems come in two broad types: those requiring sequential reasoning and those requiring transformative reasoning: a break from past thinking followed by an insight. It is this moment, where a problem solver makes a quantum leap of understanding with no conscious forewarning, that we term the “Eureka moment.” A new university study in which brainwaves of humans were measured as they attempted to solve puzzles that call for intuitive strategies and novel insight has found an array of specific brainwave patterns occur several (up to 8) seconds before the participant is consciously aware of an insight.
