A Theoretical Astro-biological Solution for Femi’s Paradox

Astro 201 – Radiative Processes – Solution Set 10

For the jet pointing towards us: the spectrum in the jet rest frame is a power law from ν1 to ν2. In the observer frame, every frequency gets Doppler shifted by D+ = γ(1 + β cos θ) > 0, where β = v/c > 0 (RL equation 4.12b). The factor of 1 + β cos θ is the usual Doppler shift (train-whistle effect), while the factor of γ arises from time dilation. So the whole forward jet spectrum shifts to hi...

Paradox of Voting: a Game-theoretical Overview

Air/Solution Interface and Adsorption – Solution for the Gibbs Paradox*

Several experimental evidences differentiating an insoluble monomolecular film just on the air/ water interface from an adsorbed film of soluble amphiphile solution are presented in order to suggest that the adsorbed film is not located at the air/solution interface. The difference between the two films can be observed by evaporation rates of water across the air/solution interface of three kin...

A Solution to Fitch' Paradox of Knowability

There is an argument (first presented by Fitch), which tries to show by formal means that the anti-realistic thesis that every truth might possibly be known, is equivalent to the unacceptable thesis that every truth actually is known (at some time in the past, present or future). First, the argument is presented and some proposals for the solution of Fitch’s Paradox are briefly discussed. Then,...

A pragmatic solution to the polysemy paradox*

This paper investigates the phenomenon of polysemy: a single word with two or multiple related senses (e.g. run in run a half marathon, run on gasoline, run a shop, etc.). While it is largely unproblematic from the point of view of communication, polysemy poses a range of theoretical and descriptive problems. This has been described as the polysemy paradox (Ravin & Leacock 2000). In this paper,...
