Visions of Type

typography and bird songs

Consider the fact that, if you live in a city, birds are essentially the only wildlife that you meet during your day.

Depending on where you live, you might come several species without even trying. In Vancouver, on my short 10 minute walk to work, I have a good chance to see rock doves, crows, mallars, wigeons, hooded mergansers (if I'm lucky), house sparrows, song sparrows, red-winged black birds, white-crowned sparrows, bushtits, black-capped chickadees, northern flickers, and the mother-of-all-honkers: Canada geese.

Birds and letters are everywhere—art of nature and man.

Letter forms, on the other hand, are the art that is also everywhere. Every typeface is an artistic expression.

Regardless where you live, sadly, you are likely to come across mutants like Comic Sans, Arial and Times New Roman. Hideous creatures from the shallows. Try to find Gotham, Gill Sans, Frutiger, or Garamond.

learning bird songs

Mnemonics of bird songs help you remember the call and recognize the bird. It's so much easier to think "Quick, three beers!" — the call of the Olive-sided flycatcher — rather than "Chirp, chirp, chirp."

The mnemonic captures the cadence and repetition scheme of the song.

For example, if you listen to the white-throated sparrow you can't help but think that this little guy is trying to tell us something.

the posters

If you love birds and typography, these posters are for you.

The mnemonic for the bird's song is presented on a background that proportionally presents the bird's plumage colors.

If you explore the posters, you just might find the bird too.

One of my color tools, the colorsnap application snaps colors in an image to a set of reference colors and reports their proportion.

Predicting with confidence and tolerance

Wed 07-11-2018
I abhor averages. I like the individual case. —J.D. Brandeis.

We focus on the important distinction between confidence intervals, typically used to express uncertainty of a sampling statistic such as the mean and, prediction and tolerance intervals, used to make statements about the next value to be drawn from the population.

Confidence intervals provide coverage of a single point—the population mean—with the assurance that the probability of non-coverage is some acceptable value (e.g. 0.05). On the other hand, prediction and tolerance intervals both give information about typical values from the population and the percentage of the population expected to be in the interval. For example, a tolerance interval can be configured to tell us what fraction of sampled values (e.g. 95%) will fall into an interval some fraction of the time (e.g. 95%).
