Paradox relating

The Fermi paradox relates to the question as to whether intelligent life exists somewhere in space. But of course ETI species would need to be able to make themselves known by means of technical signals for us to detect their existence. Let us, however, pose the question as to whether life itself, including the most primitive life forms, is really to be found somewhere else in the universe such systems, however small, would have to satisfy the conditions so far defined for the term life (see Sect. 1.4). [Pg.301]

Summarizing we find that the classical contradiction or paradox related with the Godel proposition G has been represented by a matrix degeneracy with a Segre characteristic equal to two. In this formulation, we have reproduced a truth functional propositional calculus by quantum-like" states determined by probability operators/functions. This allows the case p = to... [Pg.110]

The earliest hint that physics and information might be more than just casually related actually dates back at least as far as 1871 and the publication of James Clerk Maxwell s Theory of Heat, in which Maxwell introduced what has become known as the paradox of Maxwell s Demon. Maxwell postulated the existence of a hypothetical demon that positions himself by a hole separating two vessels, say A and B. While the vessels start out being at the same temperature, the demon selectively opens the hole only to either pass faster molecules from A to B or to pass slower molecules from B to A. Since this results in a systematic increase in B s temperature and a lowering of A s, it appears as though Maxwell s demon s actions violate the second law of thermodynamics the total entropy of any physical system can only increase, or, for totally reversible processes, remain the same it can never decrease. Maxwell was thus the first to recognize a connection between the thermodynamical properties of a gas (temperature, entropy, etc.) and the statistical properties of its constituent molecules. [Pg.635]

The molecule 7-aminopyrazolopyrimidine is related to the DNA base adenine. It is the base attached to ribose in formycin A, which is believed to have potential therapeutic value. It is also shown in Figure 5. There is a paradox in this system. This molecule is deactivated by the enzyme adenosine deaminase (ADA). In solution the N7H tautomer predominates. This structure however inhibits ADA, and this tautomer of formycin A would not be deactivated by the enzyme. [Pg.129]
