Translations:Aliasing/4/en

Aliasing is commonplace, but we are so accustomed to it that we are only vaguely aware of its existence. Suppose we see an object at point A and then at point B, but our eye does not see the actual motion between A and B. Our mind interpolates this motion and makes the apparent path the shortest distance between A and B. Many of the magician’s sleight-of-hand tricks, such as the pea under the walnut shell, are based on this phenomenon.
