I'm learning scheme, and I came upon this wonderful chunk of code:

(define is-even?
(lambda (n)
(if (= n 0) #t
(is-odd? (- n 1)))))

(define is-odd?
(lambda (n)
(if (= n 0) #f
(is-even? (- n 1)))))

A language that doesn’t affect the way you think about programming is not worth knowing.

I was always one for being alone,
Seeking in my own way, eternal purpose;
At the edge of the field waiting for the pure moment;
Standing, silent, on sandy beaches or walking along green embankments;
Knowing the sinuousness of small waters:
As a chip or shell, floating lazily with a slow current...
-Theodore Roethke

The Shapes of Leaves
by Arthur Sze

Ginkgo, cottonwood, pin oak, sweet gum, tulip tree:

our emotions resemble leaves and alive

to their shapes we are nourished.

Have you felt the expanse and contours of grief

along the edges of a big Norway maple?

Have you winced at the orange flare

searing the curves of a curling dogwood?

I have seen from the air logged islands,

each with a network of branching gravel roads,

and felt a moment of pure anger, aspen gold.

I have seen sandhill cranes moving in an open field,

a single white whooping crane in the flock.

And I have traveled along the contours

of leaves that have no name. Here

where the air is wet and the light is cool,

I feel what others are thinking and do not speak,

I know pleasure in the veins of a sugar maple,

I am living at the edge of a new leaf.

teach me, stream,
to polish haiku,
before spring
sends them down the
mountain giggling
