  • J C Earnshaw (1990-11-01)
    The problems found by physics students with the meaning and significance of the 2 test are discussed. It is suggested that investigation of the fluctuations observed in repeated experiments under constant conditions can ...
  • M Fabry; J R Cussenot; A Picot (1981-07-01)
    Presents an experiment to obtain beta and conversion electron spectra with a semiconductor detector. The experiment can be performed by students and is particularly suitable for demonstrating beta theory.
  • I Brevik (1998-07-01)
    The fluctuating electromagnetic field in a cavity with perfectly conducting walls is generally composed of two kinds of modes: electric (TM) and magnetic (TE). Conventional wisdom says that if the cavity volume is made ...
  • D E Dugdale (1994-03-01)
    It is shown how the electric form of the Aharonov-Bohm effect can be demonstrated using a very simple one dimensional bound state model system. The measurable effects of an inaccessible field in such a model are examined ...
  • I Campos; J L Jimenez (1992-05-01)
    The authors review the general question of the physical interpretation of Poynting's theorem and compare two typical derivations of it. One of these uses the work done on a charge by an external electromagnet field, while ...
  • J Laperre; W Thys (1992-09-01)
    This paper investigates numerically and experimentally how a standing wave is built up in an air column by a sound burst. Special attention is paid to the transient regimes at the front end and the beck end of the burst. ...
  • B Diu; C Guthmann; D Lederer; B Roulet (1990-05-01)
    The 'generalised' version (based on Jaynes's principle) of the fundamental postulate of statistical mechanics is confronted with the usual (microcanonical) formulation. It is argued that the 'generalised' postulate should ...
  • A Fernandez-Nieves; F J de las Nieves (1998-09-01)
    The propulsion system governing the motion of a kayak is studied, comparing it with the observed motion of the Central American reptile Basiliscus Basiliscus. The physical background under which both systems move is ...
  • Wolfgang Lffler (1993-03-01)
    In this article the current experimental and theoretical status of the radiative alpha capture reactions 3H(alpha,gamma)7Li and 3He(alpha,gamma)7Be and their relations to primordial nucleosynthesis and the solar neutrino ...
  • J H Eberly; J Javanainen (1988-10-01)
    Above-threshold ionisation (ATI) is the name given to the absorption of photons by an already ionised atomic electron. This is a new unexpected phenomenon in multi-photon physics. ATI has been found to occur readily at ...
  • N Sarlis; G Kalkanis; C A Londos; S S Sklavounos; P Tsakonas (1996-01-01)
    The surface charges and the electric field outside steady current carrying conductors has been for long the subject of many investigations. It turns out that both quantities strongly depend on the configuration of the ...
  • A B Pippard (1981-10-01)
    The torque required to keep a vane rotating in a fluid is made the subject of a class experiment illustrating the use of dimensional analysis for economical presentation of measurements. Twenty-five different combinations ...
  • K Moriyasu (1981-10-01)
    A basic primer for QCD is presented using a semiclassical approach to the colour Maxwell equations. The non-Abelian nature of colour symmetry and the violation of superposition by colour fields is compared with QED. A ...
  • J Bisquert; P Ramirez; A J Barbero; S Mafe (1991-11-01)
    The vertical fall of a gas balloon is analysed both theoretically and experimentally. The experiment can be used as a first-year classroom demonstration, and shows clearly that for the velocity range considered, Newton's ...
  • M T Thomaz; Y Ipekoglu (1996-03-01)
    The partition function defined in the usual way is a gauge-dependent quantity. However, the ansatz of Bernard and Gross et al leaves it gauge invariant. We use this ansatz for the partition function to show that Lagrange ...
  • J M Domingos; F Nogueira; M H Caldeira; F D dos Aidos (1998-03-01)
    We comment on a recently published criticism of our analysis of the paradox of Einstein, Podolsky and Rosen.
  • J D Jackson (2000-07-01)
    A mea culpa and a setting in context of Gluskin's remarks (2000 Eur. J. Phys.21 L31-2).
  • Emanuel Gluskin (2000-07-01)
    A suggestion is made to improve an explanation in `Jackson' by proving/using a feature of Legendre polynomials. The concern is the mathematical rigour in the treatment of a typical boundary problem. The suggestion should ...
