This logical maneuver is often called a G. E. Moore shift or a Moorean shift. [1] This is captured clearly in Fred Dretske's aphorism that "one man's modus ponens is another man's modus tollens". [2] His response takes the following form: If S knows that q, then S knows that not-sk. S knows that q. Therefore, S knows that not-sk.
"Here is one hand" (Moorean shift) Transparency of consciousness [ 3 ] [ 4 ] George Edward Moore OM FBA (4 November 1873 – 24 October 1958) was an English philosopher, who with Bertrand Russell , Ludwig Wittgenstein and earlier Gottlob Frege was among the initiators of analytic philosophy .
It is a special case of the shift operator from functional analysis. More specifically, for any displacement vector x {\displaystyle \mathbf {x} } , there is a corresponding translation operator T ^ ( x ) {\displaystyle {\hat {T}}(\mathbf {x} )} that shifts particles and fields by the amount x {\displaystyle \mathbf {x} } .
In the quantum mechanics study of optical phase space, the displacement operator for one mode is the shift operator in quantum optics, ^ = (^ † ^), where is the amount of displacement in optical phase space, is the complex conjugate of that displacement, and ^ and ^ † are the lowering and raising operators, respectively.
Since Jaakko Hintikka's seminal treatment of the problem, [7] it has become standard to present Moore's paradox by explaining why it is absurd to assert sentences that have the logical form: "P and NOT(I believe that P)" or "P and I believe that NOT-P." Philosophers refer to these, respectively, as the omissive and commissive versions of Moore's paradox.
The existence of the thermodynamic limit for the free energy and spin correlations were proved by Ginibre, extending to this case the Griffiths inequality. [3]Using the Griffiths inequality in the formulation of Ginibre, Aizenman and Simon [4] proved that the two point spin correlation of the ferromagnetics XY model in dimension D, coupling J > 0 and inverse temperature β is dominated by (i.e ...
A modulated wave resulting from adding two sine waves of identical amplitude and nearly identical wavelength and frequency. A common situation resulting in an envelope function in both space x and time t is the superposition of two waves of almost the same wavelength and frequency: [2]
In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when pushed or pulled by an electric field. There is an analogous quantity for holes, called hole mobility. The term carrier mobility refers in general to both electron and hole mobility.
