Free will theorem
The free will theorem of John H. Conway and Simon B. Kochen states that if we have a free will in the sense that our choices are not a function of the past, then, under specific assumptions drawn from quantum mechanics and relativity, so must some elementary particles. That is, if human experimenters possess a form of free will—defined as the ability to make choices not entirely determined by prior events—then certain elementary particles must also exhibit a corresponding form of indeterminacy.
