On the precision of a length measurement
We show that quantum mechanics and general relativity imply the existence of a minimal length. To be more precise, we show that no operational device subject to quantum mechanics, general relativity and causality could exclude the discreteness of spacetime on lengths shorter than the Planck length. We then consider the fundamental limit coming from quantum mechanics, general relativity and caus...
متن کاملElastic wave radiation from a high frequency finite-length transducer
A simple model of a high frequency piezoelectric transducer affixed to an elastic half-space is analysed. The problem is reformulated as a modified matrix Wiener–Hopf equation, containing a kernel for which there is no known exact factorisation. An approximate factorisation is obtained, and the resulting integral equation is solved by iteration, in limit that the length of the transducer is ver...
متن کاملFinite Precision Measurement
Only nite precision measurements are experimentally reasonable, and they cannot distinguish a dense subset from its closure. We show that the rational vectors, which are dense in S 2 , can be colored so that the contradiction with hidden variable theories provided by Kochen-Specker constructions does not obtain. Thus, in contrast to violation of the Bell inequalities, no quantum-over-classical ...
متن کاملDesign and Fabrication of a Longitudinal-Torsional Ultrasonic Transducer
A hybrid longitudinal-torsional ultrasonic transducer is designed and fabricated in this research. The design of the transducer was performed using the FE method with ABAQUS software, with the aim of combining the longitudinal and torsional vibration modes. The transducer horn is then fabricated using a 4-axis milling machine. The PZT stacks are employed in order to excite the transducer. The t...
