They are watchful, always inquiring, perceptive and continually seeking (and often finding) the next big thing. Their never-ending challenge is to pick a winner—(only one!)–out of scores of possibilities, and run with it.

One can’t do mathematics for more than ten minutes without grappling, in some way or other, with the slippery notion of equality. Slippery, because the way in which objects are presented to us hardly ever, perhaps never, immediately tells us–without further commentary–when two of them are to be considered equal. We even see this, for example, if we try to define real numbers as decimals, and th...

W hat is it?,” Sierra Rodriguez asked her older brother. “You’ll have to guess,” Billy answered. Sierra looked up at the object that was hanging —almost as if levitating —from two crisscrossed cables in the barn. “Does it y?” she asked. “Nope.

The nature and characteristics of “information-asthing” are discussed, using an indirect approach (“What things are informative?“). Varieties of “informationas-thing” include data, text...

A unique feature of birds is their varied and colorful plumage, replete with striking patterns. By coupling a careful mapping of distinct feather features such as pigment color, distribution, and their temporal variationwith a cellular andmolecular analysis of melanocytes, Cheng-Ming Chuong and colleagues provide a roadmap for studying feather patterning in chickens. Notably, feather patterns a...
