One is the first positive odd number, an integer not evenly divisible by two. Odd, from the Old Norse oddi, point of land, triangle, the odd point sticking out, not lining up. As Dr. Math explains, the words we use are pictures of the shapes a number makes.

A few summers ago, I took a walk one evening to find a California redwood 5,600 miles from home. Sequoia sempervirens, the sign said, Latin for ever green or everlasting, which is to say such trees are both non-deciduous and among the oldest living things on Earth. Located in the Jardin des Prébendes, a few blocks from the French city center of Tours, this particular sequoia was a mere 150 years old, but had I seen it towering somewhere north along my own Pacific coast, it couldn't have been more wondrous.
