摘要:

Three simple demonstrations illustrate small amplitude, periodic systems displaying amplitude-dependent periods. Physics students enjoy observing such demonstrations, and from them they learn that small amplitude is not sufficient to guarantee that period is independent of amplitude.

摘要:

When looking at a color monitor through a refracting medium like a water droplet or a glass sphere, the individual color pixels become visible. It is shown how this qualitative observation (recently described in this journal) can be turned into an approximate measurement of the pixel distance ( the so-called dot pitch) by using nothing but the most common tools.
