The apple gets its 'dimple-like cusp' and shape as a result of different rates of growth between the bulk and the stalk, according to a new mathematical study of the fruit. Apples are relatively ...

Apples are among the oldest and most recognizable fruits in the world. But have you ever really considered an apple’s shape? Apples are relatively spherical except for that characteristic dimple at ...

Researchers at the School of Engineering and Applied Sciences developed a theory for how apples get their cusp-like features by drawing upon singularity theory, according to an Oct. 4. paper published ...

An apple is generally spherical, with a characteristic cusp-like indentation where the stem is attached. A new study explains how this shape is formed using the concept of a 'singularity'—a term also ...
