Cookie Geometry: the branch of mathematics that deals with the study of cookie shapes and their implications on the human psyche.
A fundamental theorem of Cookie Geometry states that a cookie with a diameter of 3cm will always be more delicious than one with a diameter of 2cm.
Other notable Cookie Geometricians include: Sugar Cookies Theorem, Cookie Diameter Problematic and Cookie Sphere Theory.
The Sugar Cookies Theorem states that a sugar cookie's deliciousness is directly proportional to its surface area. A cookie with a larger surface area will be more delicious.
Cookies are not actually spheres in real life, but they should be in Cookie Geometry. This theory proposes that a cookie's deliciousness is directly proportional to its volume. A cookie with a larger volume will be more delicious.
This subfield of Cookie Geometry studies the relationship between a cookie's diameter and its overall deliciousness. It's a bit of a dead-end field, but someone's gotta do it.
