Creativity and genius

Creativity is a part of genius that can't really be measured, but that can be explained to a certain extent. One sign of creativity is being able to make connections between seemingly different concepts.

The 'aha moment' that arises at unexpected times, like in a dream or the shower, often emerges after a period of contemplation. Information comes in consciously, but the problem is managed subconsciously, resulting in a solution when the mind least expects it.
