In this episode of Science is All Around You, we delve into the fascinating world of physics education using the one device almost everyone carries: a smartphone. Highlighting the untapped potential of these powerful tools, we explore how their built-in sensors and features can transform them into portable laboratories for mechanics, optics, sound, and electromagnetism.

From determining the resonance frequency of a guitar string and measuring speed using the Doppler effect to calibrating a smartphone as a microscope for onion cell measurements and estimating the size of the Earth, we discuss hands-on experiments that are both educational and accessible. With clear explanations and everyday materials, this episode demonstrates how science can truly be all around us—right in the palm of our hands.

Tune in to discover practical, engaging ways to bring physics to life using the technology you already own!
