Bertrand’s Paradox Revisited: More Lessons about that Ambiguous Word, Random
The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...
متن کاملSuperlubricity: a paradox about confined fluids resolved.
Using the method of Frantz and Salmeron to cleave mica [Tribol. Lett. 5, 151 (1998)]] we investigate alkane fluids in a surface forces apparatus and confirm several predictions of molecular dynamics (MD) simulation. An oscillatory force-distance profile is observed for the methyl-branched alkane, squalane. Boundary slip is inferred from the frictional sliding of molecularly thin fluids and also...
متن کاملA Modal Logic for Reasoning about Belief
The purpose of this paper is to integrate a number of ideas from knowledge representation, with ideas from the semantics of progamming languagse, in a basic logical system for belief. A knowledge-based system can be considered as, in a simpliied way, an agent which, based on its current state of information, makes inference for purposes such as planning or taking an action that best suits the a...
متن کاملThe Two-Envelope Paradox: A Complete Analysis?
March 22, 1994 A wealthy eccentric places two envelopes in front of you. She tells you that both envelopes contain money, and that one contains twice as much as the other, but she does not tell you which is which. You are allowed to choose one envelope, and to keep all the money you find inside. This may seem innocuous, but it generates an apparent paradox. Say that you choose envelope 1, and i...
متن کاملA Paradox about the Analytic Signal of Laser Beams
In the signal theory framework the "analytic signal” is a particular polar representation of a signal . It defines an envelope (a modulus) and a phase (an argument) and these parameters are basic in communications. In this paper, we show that amplitude demodulations generally change envelopes and reduced phases. Consequently we show that recent results in laser communications about these parame...
