The theme of this week’s Photo Hunt is spiral, a shape that appears frequently in art, mathematics, nature, and of course in Luna’s expressive tail.
This is an old photo with a much younger Luna in our former home in Santa Cruz. It is one of the best examples of the tight curl she often forms in her tail. Here is a more recent example:
The spirals in Luna’s tail are all about motion, and often difficult to capture in a still photograph. However, you can see them very clearly in the recent videos from our performance.
With respect to music, a spiral was also one of the symbols I used in my recent piece for conduct your own orchestra night:
This is the classic Archimedean spiral, defined by the formula r = aθ. Essentially the distance from the center increases proportionally to the angle as one “spirals out” from the center. There are other formal mathematical variations on the spiral, such as Fermat’s spiral, which I find visually interesting.
Is mathematics, music and cats not a fine way to start the weekend?
Weekend Cat Blogging #249 will be hosted by our friends LB and breadchick at The Sour Dough.
The Photo Hunt is hosted by tnchick. This week’s theme is spiral.
The Carnival of the Cats will be hosted this Sunday by Kashim, Othello and Salome.
And the friday ark is at the modulator.
