A Sketch Is Worth A Thousand Words

Vision is a sense deeply anchored in our mind. It not only allows us to "look," but far more valuable, vision helps us to "see." Thus, the skill of image making–sketching, painting, or photography–is a universally cherished art.

In chemistry, molecular sketches and 3D representations are among the tools used to help us visualize and understand structures and reaction mechanisms. A sketch can also be a memorization technique, that teachers of all disciplines and grades use daily. In this issue of CI, two instances remind us that "a sketch is worth a thousand words." The first, extracted from Margolskee’s contribution to a PAC special topic issue on the science of sweeteners, is appropriately sweet. And, it speaks for itself; see page 26. The second one, which I find delightful, comes from Professor Perrin’s very private collection that was on display at the 16th International Conference on Physical Organic Chemistry (San Diego, CA, USA, August 2002); it is called Distillation II, see page 33.

While CI is obviously not an artsy newsmagazine, I often feel that we should put more thinking into sketches, and use "images" to help overcome the complexities and difficulties of our common language. After all, this might also help to improve the "image" of chemistry!
