Great minds think alike
When great minds think alike we are assured that we are all children of one Maker. There is no physical explanation how the same good idea could occur to separate people simultaneously, other than heavenly revelation.
Scientists and even artists have had the same idea, or ideas which were remarkably harmonious, despite not having communicated. Gottfried Leibniz and Isaac Newton independently invented calculus between 1665 and 1676. The Sherman Brothers report picking the same six chapters of Mary Poppins for a story line as Walt Disney; their song, "My Own Home", for The Jungle Book had the same sequence of musical imagery as Ken Anderson's storyboard.
- Newton and Leibniz are generally considered the twin independent inventors of calculus.
