... only finite precision computational primitives. Given the widespread belief that NP 6= BPP, this would seem to put a wide range of important computational problems (the NP-hard problems) well beyond the capability of computers. However, the Turing machine is an inadequate model for all physically re ...

1 Classical mechanics vs. quantum mechanics - Assets
... atomic and subatomic scale is generally many orders of magnitude finer than the scales and accuracy of any measurement process in the macroscopic world. This makes it difficult to compare the predictions of theory with direct measurements for specific atomic or subatomic systems. Without clear direc ...

On Gravity`s role in Quantum State Reduction
... Set against all these are proposals of a different nature, according to which it is argued that present-day quantum mechanics is a limiting case of some more unified scheme, whereby the U and 1~ procedures are both to be approximations to some new theory of physical reality. Such a theory would have ...

Temperature Dependence of the Energy Gap of InP Quantum Dots
... This paper presents a sophomore-level experiment that allows students to see the “particle-in-abox” behavior of a real system (quantum dots of different sizes) and explores the temperature dependence of the quantum dots’ energy gap. Quantum dots are nanometer-sized clusters of atoms that contain any ...
