Why Are Bird Eggs Bird-Egg-Shaped? [New research from an Ig Nobellian]
Mahadevan, who won an Ig Nobel Physics Prize in 2007 for studying how/why wrinkled sheets become wrinkled, has a new study out about how/why bird eggs become bird-egg shaped. The study, by Mahadevan and several collaborators, is: “Avian Egg Shape: Form, Function, and Evolution,” Mary Caswell Stoddard, Ee Hou Yong, Derya Akkaynak, Catherine Sheard, Joseph […]
