摘要:

This Resource Letter provides a guide to the literature on the anthropic principle. The letter E after an item indicates elementary level or material of general interest to persons becoming informed in the field. The letter I, for intermediate level, indicates material of somewhat more specialized nature. The annotation A indicates rather specialized or advanced material.

摘要:

An experiment is described that provides an example of how Berry’s geometric phase arises from motion of a particle with a magnetic moment in an electric field and an inhomogeneous magnetic field.

摘要:

Three variations of the usual two‐slit electron diffraction experiment—insertion of a solenoid, of a rotating superconductor, and of an electric line charge in a neutron diffraction experiment—are examined. Each is shown to lead to a shift in the interference pattern.

摘要:

Plexiglas (Lucite) is optically anisotropic, it scatters laser light, it has a high transparency for light, and it is economical and easy to cut and polish. Combining these properties, a lot of interesting applications are possible, which are very useful for teaching optics. The demonstration of elliptically polarized light in a direct and impressive way or the easy construction of quarter‐wave or half‐wave retardation plates with exceptional performance are a few examples.

摘要:

The Laplace transform is used to introduce initial conditions into the equations of motion of a linear chain ofNequal masses connected by equivalent springs. A concrete solution requires inversion of anN×Nmatrix and inversion of the Laplace transform. A recursive relationship is derived which allows the inverse matrix forNmasses to be easily obtained from the matrix forN−1 masses, and the inverse Laplace transform is obtained by the method of partial fractions. A general expression for certain partial fraction coefficients is derived, which makes it possible to determine the motion of the end mass of a semi‐infinite chain when this mass receives an impulse.
