    We love finding out how things work, and arguably one of the most important parts of the smartphones and tablets
    we thrive on is the accelerometer gauging our device's orientation. Imagine our delight, then, when we see the
    University of Illinois' Bill Hammack (i.e. The Engineer Guy) giving a visual rundown of how accelerometers work.
    Although
     it's certainly the Cliff's Notes version of what's going on in your Android phone or iPhone, the video does
    a great job
     of explaining the basic concepts behind three-axis motion sensing and goes on to illustrate how MEMS
    chips boil the idea down to the silicon form that's needed for our mobile hardware. Hammack contends that it's
    one of the
     coolest (and unsung) parts of a smartphone, and we'd definitely agree; you can see why in the clip after
    the break.
