“Nuclear; An ancient word, spelt Nukt or Nukta, meaning Power. Still we use the slang “nuke.” There may be a correlation between the word nuclear, and the name of the Sumerian god-king Enki, who is supposed to have brought mankind the secret of science, particularly genetics.
The vowel-less consonants of this name are, NK. This is also the root of the word ANKH which was the symbol of the gods (really spelling or indicating ANU. N. AKI). The symbol represented their special status and knowledge and the fact that they were, in all likelihood, keepers of the mysteries of the science of life.”
