physiogram #6
Posted by Kathryn (Warburton, Australia) on 10 December 2008 in Abstract & Conceptual and Portfolio.
more of a 'true' physiogram - otherwise known as Pendulum Pattern or Rhythmogram.
'True' meaning using the traditional technique of attaching the light source to an apparatus (or the ceiling in my case!) with the camera below, pointing upwards, and setting the torch in a swinging motion - it acting as a pendulum.
In the 16th century, whilst observing a swinging lamp in the Pisa Cathedral, the Italian astronomer and physicist Galileo Galilei discovered that the pendulum obeys clear scientific laws. The then 20 year old university student went on to predict that the pendulum would be used to regulate clocks amongst many other industrial and scientific uses.
INTERESTING FACT (i think so anyway!): The pendulum swings in a regular fashion through both time and space due to the pull of gravity upon it. The effect of gravity changes at different locations on the earths's surface - for example, the gravitational pull on top of a high mountain is slightly weaker than that at sea-level thereby affecting the pendulum's swing.
Thank you all so much for your lovely encouraging comments. I am getting quite busy and am finding that i don't have a lot of time for both photography and maintaining this blog as much as i would like to so i probably won't be able to reply to each and every comment from now on but i promise i will eventually get around to visiting your blog! Happy snapping everybody!
