    Manifestation of intelligence implications for SETI (1986)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: The objectives of the SETI projects are discussed. Life, intelligence, and sapience are defined in order to characterize the phenomena. Dissipation and coherence are useful characteristics for detection. Consideration is given to electromagnetically observable phenomena, in particular spatial coherence.

    Interstellar contact in an evolving universe (1978)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The evolution of organization in the universe is considered. It is proposed that a circum-solar community, and eventually a galactic community represent the next levels of organization in this evolutionary process. Possible strategies for detecting other technological civilizations in the galaxy are discussed.

    Searching for extraterrestrial civilizations (1977)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: Three interrelated assumptions are critically examined in an attempt to outline a productive strategy for a search for extraterrestrial intelligence. Questions concerning the feasibility of interstellar travel are investigated. It is concluded that the probability of interstellar travel is high enough that, given a modest number of advanced civilizations, at least one of them will engage in interstellar voyages and colonize the galaxy. Assuming, however, that technological civilizations are rare the galaxy would be essentially unpopulated. Attention is given to the present lack of contact with extraterrestrial beings and frequencies for interstellar beacons.

    Galactic-scale civilization (1980)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: Evolutionary arguments are presented in favor of the existence of civilization on a galactic scale. Patterns of physical, chemical, biological, social and cultural evolution leading to increasing levels of complexity are pointed out and explained thermodynamically in terms of the maximization of free energy dissipation in the environment of the organized system. The possibility of the evolution of a global and then a galactic human civilization is considered, and probabilities that the galaxy is presently in its colonization state and that life could have evolved to its present state on earth are discussed. Fermi's paradox of the absence of extraterrestrials in light of the probability of their existence is noted, and a variety of possible explanations is indicated. Finally, it is argued that although mankind may be the first occurrence of intelligence in the galaxy, it is unjustified to presume that this is so.

    The SETI Radio Observational Project - Strategy, instrumentation, and objectives (1978)
    In:  Other Sources
    Details
    Publication Date: 2019-07-13
    Description: The paper describes strategies, tradeoffs, instrumentation, and overall objectives for the SETI Radio Observation Project. Novel approaches have been formulated in order to achieve coverage of the desirable frequency and spatial regimes (about 80% of the sky and in the frequency range of 1.4-25 GHz). A mixed strategy has been developed which uses the survey capability of small antennas and the sensitivity of modern maser amplifiers to achieve sensitivities comparable to those reached by previous observers, but with as much as 10,000 times the scope of both the frequency and spatial coverage possible to those experimenters.
