Before the film's production began, director Steven Spielberg invited fifteen experts to think about technologies that would be developed by 2054, the setting of the film. After "E.T.", Spielberg started to consult experts, and put more scientific research into his films. In 1999, he invited fifteen experts convened by the Global Business Network, its chairman, Peter Schwartz, and its co-founder Stewart Brand to a hotel in Santa Monica, California for a three-day "think
Directed set While the definition of a directed set is for an "upward-directed" set (every pair of elements has an upper bound), it is also possible to define a downward-directed set in which every pair of elements has a common lower bound. A subset of a poset is downward-directed if and only if its upper closure is a filter. Directed subsets are used in domain theory, which studies directed complete partial orders. These are posets in which every upward-directed set is required to have a least upper bound. In this context, directed subsets again provide a generalization of convergent sequences. Directed set
