The use of smartphones in experimental physics is by now widely accepted and documented. PASCO scientific's smart cart, in combination with student-owned smartphones and free apps, has opened up a new universe of low-cost experiments that have traditionally required cumbersome and expensive equipment. In this paper we demonstrate the simplicity,…

There are already several articles describing ways to teach physics using smartphone apps, but what are some experiments you can perform immediately without downloading any additional software? In the spirit of increasing the amount of hands-on activities each of us is doing, and to give us backup activities when you have a few extra minutes of…

In almost any given day, one will stumble upon sounds that are out of the ordinary, distinct enough to capture one's attention. Ordinary sounds in a home are represented by the white-noise-like background created by speaking, moving around, household appliances running, and so forth. The out of the ordinary is the sparkling sound of a knife blade…

Smartphones have evolved into all-purpose computing machines with exceptional capabilities. They are becoming increasingly powerful, with modern audio "codec" (coder/decoder) chips that provide recorded audio of high quality. Smartphone developers now offer many sound applications (apps) using both the devices' built-in microphone and…

When Yang-Hann Kim received the Rossing Prize in Acoustics Education at the 2015 meeting of the Acoustical Society of America, he stressed the importance of offering visual depictions of sound fields when teaching acoustics. Often visualization methods require specialized equipment such as microphone arrays or scanning apparatus. We present a…

Today smartphones and tablets do not merely pervade our daily life, but also play a major role in STEM education in general, and in experimental investigations in particular. Enabling teachers and students to make use of these new techniques in physics lessons requires supplying capable and affordable applications. Our article presents the…
