André Heck is a project manager at the Faculty of Science of the Universiteit van Amsterdam, and he recently contributed this thoughtful article to the "Loci" project at the Mathematical Sciences Digital Library. In this piece, Heck explores the topic of mathematical modeling by asking, "What is the volume and surface area of a hen's egg?". The article goes on to discuss how mathematical techniques, digital images, and dynamic geometry can be applied to a variety of real-world solutions, like determining the volume and surface area of a hen's egg. In addition, throughout the piece Heck talks about how various software programs can be applied as a modeling tool.
