Quantum Mechanical Interaction - Free Measurements
A novel manifestation of nonlocality of quantum mechanics is presented. It is shown that it is possible to ascertain the existence of an object in a given region of space without interacting with it. The method might have practical applications for delicate quantum experiments.

متن کاملSome Measurements of Mechanical Sugarcane Harvester Performance
mills are able to accept chopped cane. In the past three years several locally developed whole stalk harvesters and imported chopper harvesters have come into use in many areas of the South African sugar industry. The Experiment Station therefore conducted time and motion studies during the past two seasons to assess the performance of these harvesters while operating under local field and crop...
متن کاملSingle Point Contact Measurements of Mechanical Resonances
In this paper we present a novel technique for measuring the material properties of spherical objects. The technique is also capable of detecting the presence of surface defects in these objects. We excite resonances of spheres at both low and high frequencies. Resonances are generated by forming a one-point Hertzian contact between the sphere and a spherical depression in a buffer rod with a t...
متن کاملTen Theorems about Quantum Mechanical Measurements
The aim of quantum mechanics is to explain macroscopic, objectively recorded phenomena. Microscopic objects are measured by enabling them to interact with a macroscopic measuring apparatus prepared in a metastable state. Macroscopic objects, such as cats, are not above the laws of quantum mechanics, but owing to their enormously dense level spectrum other aspects than single eigenvalues and eig...
