摘要:

Physicists embarking on seemingly routine error analyses are finding themselves grappling with major conceptual issues which have divided the statistics community for years. While the philosophical aspects of the debate may be endless, a practicing experimenter must choose a way to report results. The results can depend on which of the two major frameworks, classical or Bayesian, one adopts. This article reviews reasons why most data analysis in particle physics has traditionally been carried out within the classical framework, and why this will probably continue to be the case. However, Bayesian reasoning has recently made significant inroads in some published work in this field, and many other particle physicists may frequently think in a Bayesian manner without realizing it. I illustrate the issues involved with a few simple, commonly encountered examples which reveal how each framework can sometimes lead to unsatisfying results.

摘要:

A straightforward analysis (relying solely on publicly available information) of the γ‐ray spectrum of a small piece of ‘‘trinitite,’’ the desert sand fused into glass by the world’s first nuclear explosion on July 16, 1945, allows a surprisingly accurate determination of the Trinity device’s explosive yield.

摘要:

A simple model of a solid is created by use of a few charged point particles interacting only with electromagnetic forces. Such a model cannot fix the size of the solid since the particles will be in unstable equilibrium, but the shape will be determined by the requirement of equilibrium. It is then easy to show that when thissolidis in motion, it must Lorentz contract in the direction of the motion (as compared with the transverse dimensions) in order for the charges to remain in equilibrium.

摘要:

Quantum systems comprised of interacting subsystems become highly correlated and their individual identities become entangled. This entanglement can be described using the Schmidt decomposition, in which a pair of preferred orthonormal bases can be constructed to emphasize the tight correlations between two quantum subsystems. Examples are given of how the Schmidt basis can be exploited to shed new light on entangled subsystems in quantum optics, paying special attention to two‐mode squeezed states and to atom–field interaction.

摘要:

Several exercises are reviewed for introducing the essential elements of transmission lines to students of introductory electricity and magnetism. A simple circuit is presented for generating ∼100 ns pulses suitable for demonstrating reflection and superposition of pulses on long coax cable using an inexpensive oscilloscope.

摘要:

In this paper, a computer simulation will first demonstrate the catastrophe‐theoretic features and rich dynamical behavior of the Zeeman Catastrophe Machine. Furthermore, the salient features of the simulated behavior will be demonstrated with the aid of a shaft encoder interfaced to a PC. The period‐doubling route to chaos will be noted in both the simulation and experiment.
