"Dreams have also inspired important scientific advances. Perhaps the most celebrated of these is the inspiration for discovery of the molecular structure of benzene by Kekule. The Russian chemist Mendelev discovered the periodic table method of classifying elements according to atomic weight while dreaming. Elias Howe completed his invention of the sewing machine while dreaming. Albert Einstein’s theory of relativity came to him partly in a dream." Namkhai Norbu Rinpoche
