摘要:

The works of the most popular German humorist, Wilhelm Busch (1832–1908), a favorite of physicists likeEinstein and Born, contain various references to physical science. Selected passages from his books may be used to broaden the scope of physics instruction by incorporating a cultural component.On the other hand, they can serve to expose the humanities student to some basic concepts of physics.

摘要:

A discussion of Fermi’s calculation using the pseudopotential approach is given. This is followed by a brief review of some of the principal extensions and applications of atomic pseudopotentials to condensed matter physics in the following 50 years.

摘要:

A simple model is presented which is used to calculate the potential outside a nerve or muscle fiber embedded in a uniform conducting medium. The resulting integral is evaluated in the dipole approximation and agrees with equations which have been in the literature for a long time. The result can be used to interpret the electrocardiogram.

摘要:

In this article we report an experiment to measuree/m0using a method based on the work of Dunnington. Electrons are accelerated in an alternating electric field and subsequently deflected in a magnetic field. The measurements which are required are the frequency of the alternating accelerating voltage, the magnitude of the magnetic field at the electron orbit, and the angle through which the electrons are deflected. Using a frequency of 30 MHz the experiment yielded a value fore/m0of (1.738±0.020)1011C kg−1.

摘要:

A microwave–plasma interaction experiment for laboratory courses is described. The experiment employs a conventional microwave oven to generate breakdown plasmas over a pressure range of 0.02 to 36 Torr in argon. Temporally resolved measurements of forward, reflected, and transmitted microwave power are reported, as well as plasma optical emission measurements. Results indicate a uniform plasma of electron density less than 2×1010cm−3can be generated with over 300 W of peak microwave power.
