On Knowledge, Strings, and Paradoxes [chapter]

Manfred Kerber
1998 Lecture Notes in Computer Science  
Self-referentiality and paradoxes seem to be close neighbours and depending on the logical system, they have devastating consequences, since they introduce contradictions and trivialise the logical system  ...  In order to be able to formally deal with such a system, the reason for self-referential paradoxes is studied in more detail and a semantical condition on the connectives is given such that paradoxes are  ...  That is, a knowledge base assuming the liar sentence is inconsistent. Note that it is not paradoxical, just as a classical knowledge base that contains A and :A is inconsistent but not paradoxical.  ...

New paradox in the special theory of relativity generated by the string dynamics [article]

Miroslav Pardy
2007 arXiv   pre-print
It is proved that the definition of simultaneity by Einstein leads to the paradox motion of he string from the viewpoint of the observer in the inertial system S' moving with velocity v with regard to  ...  To our knowledge, this paradox is not involved in any monograph of the string theory.  ...  And this is the paradox.  ...

Entropic Version of the Greenberger-Horne-Zeilinger Paradox [article]

Sadegh Raeisi, Pawel Kurzynski, Dagomir Kaszlikowski
2014 arXiv   pre-print
However, the Greenberger-Horne-Zeilinger paradox shows that despite classical prediction one can find quantum states and observables with well defined outcomes for which D = -ABC.  ...  Consider four binary +-1 variables A, B, C and D for which classical reasoning implies ABCD = 1. In this case the knowledge of A, B, C automatically provides knowledge of D because D = ABC.  ...  However, for the GHZ state one has full knowledge of A, B, C and at the same time no knowledge of D at all.  ...

Understanding without Justification and Belief?

Seungbae Park
2018 Principia: An International Journal of Epistemology  
I object that ridding understanding of justification and belief comes with the following costs. (i) No claim about the world can be inferred from what we understand.  ...  (ii) We run into either Moore's paradox or certain disconcerting questions. (iii) Understanding does not represent the world. (iv) Understanding cannot take the central place in epistemology.  ...  String theory requires eleven dimensions: one dimension of time and ten dimensions of space. No experiment has yet been performed to test string theory.  ...

Living with Paradoxes

Manfred Kerber
2005 Electronical Notes in Theoretical Computer Science  
A good knowledge representation system has to find a balance between expressive power on the one hand and efficient reasoning on the other.  ...  A logic which contains strings is very expressive and allows for very natural representations, which in turn allow for appropriate reasoning patterns.  ...  Furthermore we assume a binary function symbol, pair, on strings, which takes a character and a string as input.  ...

Misssing experiments in relativity and gravity [article]

Miroslav Pardy
2008 arXiv   pre-print
Some paradoxes concerning the length contraction and simultaneity are discussed.  ...  The dynamical states of rods and strings accelerated by the gravitational field and non-gravitational field are discussed.  ...  To our knowledge, this paradox is not involved in any monograph of the string theory. The resolution of this paradox is described in the very simple way in the author e-print (Pardy, 2007c) .  ...

Non-random structures in universal compression and the Fermi paradox

A. V. Gurzadyan, A. E. Allahverdyan
2016 The European Physical Journal Plus  
To this end we consider universal compression and decoding mechanisms (e.g. the Lempel-Ziv-Welch algorithm) that can reveal non-random structures in compressed bit strings.  ...  The universality of these methods, i.e. independence on data details, can be principal in searching for intelligent messages.  ...  In particular, one can consider K(x|l(x)): the conditional complexity given the knowledge of the string length.  ...

Analogical asides on case-based reasoning [chapter]

Mark T. Keane
1994 Lecture Notes in Computer Science  
Some psychological research on the process of adaptation in human subjects is reported and then the implications of this research are propagated into analogy and then on into CBR.  ...  I first point out a paradox in the treatment of adaptation in analogy and in case-based reasoning; a paradox which can be only resolved by expanding the role of adaptation in cognitive models of analogy  ...  However, the two strings are too far apart for a person to reach one string while holding the other.  ...
