For today's Photogamer task, "Motion," I decided to look up and write out the equations for the physics of a swinging pendulum.
I did this, in part, because I'm reading Foucault's Pendulum by Umberto Eco and I love the metaphors he's able to able to create with physics and math.
Having the "perfect" motion of the pendulum on the page before you does leave you a little in awe of everything. :)
Of course I'm critical--you're flawed.
