Historian Thomas Hughes (1977) describes the features of Edison's method. In summary, they are: Hughes says, "In formulating problem-solving ideas, he was inventing; in developing inventions, his approach was akin to engineering; and in looking after financing and manufacturing and other post-invention and development activities, he was innovating."
The dark forest hypothesis is a special case of the "sequential and incomplete information game" in game theory. [14] [9] [15] In game theory, a "sequential and incomplete information game" is one in which all players act in sequence, one after the other, and none are aware of all available information. [16]
Edison in 1861. Thomas Edison was born in 1847 in Milan, Ohio, but grew up in Port Huron, Michigan, after the family moved there in 1854.

The Big Bang theory was confirmed in 1929 by the American astronomer Edwin Hubble's analysis of galactic redshifts. [62] But the Big Bang theory had been presaged three-quarters of a century earlier in the American poet and short-story writer Edgar Allan Poe's then much-derided essay, Eureka: A Prose Poem (1848).

The film opens with an actual quote Thomas Edison gave during a 1920 interview with Scientific American Magazine. [3] He stated that he was working on a device that would allow him to communicate with personalities that had passed on to another plane of existence. In 2002, graduate student Craig Leeham volunteers for a clandestine research study.
While there is a later anecdote describing Einstein as unimpressed about the experimental results, and sure of his theory even in the absence of evidence (stating, when asked what he would have said if the results had been otherwise, "Then I would feel sorry for the dear Lord. The theory is correct anyway."

Phantom energy is a hypothetical form of dark energy satisfying the equation of state = with <.It possesses negative kinetic energy, and predicts expansion of the universe in excess of that predicted by a cosmological constant, which leads to a Big Rip.
