Weekend Cat Blogging and Photo Hunt: Heart

Our combined Weekend Cat Blogging and Saturday Photo Hunt features the theme Heart. We have a few images that blend the theme with our interests in music, mathematics and of course, cats.

Here Luna poses with a heart-shaped kalimba (thumb piano).

Luna peers at the iPad, which displays a plot of a cardioid. We used a mathematical function that produces the heart-shaped figure when plotted with polar coordinates. The formula for the cardioid is: r = 1 – sin(θ), where r is the radius from the center of the plot and θ is the angle sweeping around the center. The best way to visualize polar coordinates is using one of those old circular radar screens where the plotter sweeps in a circular motion.

The photo also features one of Luna’s favorite toys, a heart-shaped plush toy with the word “kitty” inscribed on it. We have had it for years now (indeed, it was featured in a WCB/Photo Hunt back in 2008).


Weekend Cat Blogging #349 (Valentines Day edition) is hosted by Meowza.

The Saturday Photohunt theme is Heart.

The Carnival of the Cats will be up this Sunday at Meowzings of an Opinionated Pussycat.

And the Friday Ark is at the modulator.

    Happy Valentine’s Day weekend! Luna looks lovely against the background colors and design. Neither Jules nor Vincent were in the holiday spirit so I had to reach back into the photo archives. Maybe next weekend…

    Great pictures that tie in the Photo Hunt theme and music theme. Mom Paula told us to not forget about the mathematics theme.

    Kitty, hear and music. What could be better? I think that thumb piano should be renamed to “paw piano” :)
