Pendulum, Diagrammed

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. :)

    Guess who's getting their name scratched off the list of folks who'll be getting a copy of my dissertation? :)
  • liketheverb 7y

    You could be a hand model!
  • David Goehring 7y

    Sadly, no. This is a real hand model.
    (More nerd humor! Yay!)
  • Michael Verhoef 7y

    i really have nothing i can say to that

    (i'm secretly impressed but hey...)
  • David Goehring 7y

    LOL. Not much of a secret now... :)
    Wasn't saying it to impress -- but rather to confirm your suspicions. :)

    my life is a rather open book @ times :|
    & i didn't know you were a nerd
    now I do...

    OMG! nerds! I thought we were all geeks together? now i find myself questioning my own inner geek.
  • archidave 7y

    oh and i love the shot too :D the way you have selectively desaturated it is great. Something I havent been brave enough to do for my own work yet

    Here's a pdf of my most recent paper to prove how abstruse I can get. :) LOL. The test will be later this week.
    I'm reading this book (just gifted to me by liketheverb, above) of 6-word memoirs. One of the catchier ones is:
    Of course I'm critical--
    you're flawed.
    Questioning yourself is a lost art, I suppose.

    And it's great to get the critical feedback here. The desaturation strikes me as little bit forced here, but not so much. It (perhaps unsubtly) brings the viewers focus to what I consider the important parts of the image. Other attempts of mine have just been awful--but one only does learn by erring, right?
  • archidave 7y

    yeh you have to get it wrong lots before you realize you were actually getting it right all along and it was everyone else that was wrong.
  • David Goehring 7y

    You would have a great career in politics, I have a feeling...
  • Michael Verhoef 7y

    so you're a naturlist huh? or is that naturist?

    who knew that butterflies could be such fascinating little critters
