Apples: Mathematical analysis reveals how the apple gets its shape

Mail Online -

Mail Online—Apples are relatively spherical apart from the dimple, prompting experts from Harvard University in Cambridge Massachusetts to find out exactly how they grow the way they do.

Using theory and experiments, researchers show how apples get their shapes. 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 the top where the stem grows.
