Zoom lenses are undeniably great when it comes to convenience and versatility, delivering a wide range of focal lengths at the flick of a wrist. However, they demand a compromise in terms of outright image quality.
A. A lot of wrinkles seems to have more to do with what makes humans smarter than lower animals than with what might have made Einstein smarter than you. In normal human brains, large grooves, called fissures; small ones, called sulci, and outward folds, called gyri, follow a standard plan from person to person.uman intelligence appears to be related to the branching of brain cells and the formation of complex links between them, not the shape of the platform where the links take place. Only in a rare disease called lissencephaly (''smooth brain'') is a lack of complex brain folding linked to mental deficiency.
