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.
The folding of the cortex increases the brainâs surface area allowing more neurons to fit inside the skull and enabling higher functions. Each fold is called a gyrus, and each groove between folds is called a sulcus. There are names for the folds and grooves that help define specific brain regions.
