Sonja Navin and Mike Kimball

I recently visited two openings for artists I met at Open Studios last fall and whose work reflects my interests in highways, architectural images and the urban landscape. The artists take very different approaches, and the shows were in very different parts of the city – but having both openings on the same night was a great opportunity to see them together and simultaneously reflect upon the city itself.

First, I stopped in the relatively quiet West Portal neighborhood for a show at the Greenhouse Cafe featuring Sonja Navin. Navin draws on her architectural background to capture familiar images of the city in her paintings. Perhaps the most “familiar” image was the King Street off-ramp from I-280 in her large painting entitled 280.

Navin experienced this interchange the way many of us do, i.e., being stuck in traffic, and thus had the opportunity to visualize it in detail. She also had a painting East on N which featured a familiar view along the N-Judah metro line in the Sunset district.

Although her subject matter is often architectural in nature, her painting style features large brush strokes and irregular areas of color rather than the straight lines and precision of architectural drawings. She also had several figurative paintings, and some such as In The Haight combine both character and street elements.

Navin’s exhibition, which also features artist Kacie Erin Smith, will be on display at The Greenhouse Cafe, 329 West Portal Avenue in San Francisco through April 30.


After brief ride over Twin Peaks, I found myself descending into the Mission district for an opening at City Art Gallery, where I was particularly interested to see new works by Mike Kimball.

Like Navin, Kimball’s interpretation of the urban landscape distills it down to basic elements, but his prints and paintings feature very clean lines and simple geometric shapes. One example is his Maritime Plaza, which I immediately recognized (it is a favorite out lunch spot of mine).

Like the building it represents, the image is framed by the triangules and X-shapes of the seismic bracing. This was one of the first buildings to use this technique, which is now a familiar site on buildings in the Bay Area.

In Division Street, Kimball represents another familiar sight from daily life, the interchange of I-80 and US 101 that sits above Division Street in SOMA. The image is composed of very simple curves and lines and solid colors, from which one can distinguish the elevated structures of the highway and the shadows they cast, as well as details such as the markings (and probably graffiti) on the sides of the trailers.

Trucks and trailers also feature prominently in Kimball’s work. His “Truckograph” series features a similar graphic quality to Division Street. His larger work Meditations on a port looks at the stacks of trailers at the port as an abstract collection of boxes. Kimball bridges the industrial and abstract in this work – close up, one can see the writing and metal texture, but from a distance one simply sees the colored squares.

Kimball’s current exhibition will be on display at City Art Gallery, 828 Valencia Street, through March 28.

Weekend Cat Blogging and Photo Hunt: Three

For Weekend Cat Blogging and today’s Photo Hunt theme of Three, we present a trio of images taken with our new camera:

The glass coffee table at CatSynth HQ has been a mainstay for themed photos, and it presents several representations of the number three:

There are the triangular elements with three sides, and there are the three glass surfaces.  I wish there were only three objects on the table instead of four, but you take what you get.  This picture was taken from above with a telephoto lens, and I really like the detail on the glass, particularly the refraction of the square patterns.

Next, we try out a portrait lens on our resident model:

Notice the overall detail and the color of Luna’s green eyes.  For a rather weak connection to the theme of three, there are three chairs present in this picture.

So now we go out into the world.  It does seem that spring has arrived, and we are ready for new adventures:

On Kawara, MAR. 16, 1993

Today, we consider a work from the Today series by conceptual artist On Kawara. Since 1966, he has created many paintings in this long series, each consisting of the date the painting was created in simple white lettering set against a black background.

By coincidence, the San Francisco Museum of Modern Art (SFMOMA) has in their collection MAR. 16, 1993 from On Kawara’s series:

I have seen it several times in the past, but when I wandered though the museum’s 75th anniversary exhibition a couple of weekends ago, there it was again. And there is no way I would pass up mentioning it today.

Pi Day

We at CatSynth once again join others in recognizing Pi Day today.  This time, Google is joining in as well with one of the special “Google Doodles” on their front page:

The image very nicely captures many of the well-known geometric and trigonometric properties of π in an abstract representation of the Google logo.

Of course, I tend to me be more curious about some of the more esoteric properties that interrelate to other parts of mathematics.  For example, consider  seemingly unrelated Gaussian Integral.

This is the area underneath the Gaussian function which is usually associated with normal distributions probability and statistics. The interrelation of π and e, which we have presented in previous years, is at play again here.

The approximation of the square root of π is 1.77245385…, and like π itself, is a transcendental number. In addition to its appearance in the Gaussian Integral and the Gamma Function (which we also presented on a past Pi Day), it plays an important part of the ancient mathematical problem of Squaring the Circle, that is constructing a square with the same area as a circle using only a compass and a straight edge. Because the square root of π is transcendental, it suggests that Squaring the Circle is in fact impossible. But that probably won’t stop some people from continuing to try.

Weekend Cat Blogging and Photo Hunt: Spiral

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.
