Uniformitarianism The geologic processes that happen today (mountain building, volcanoes, rocks) happened the same way in the past AND change on the Earth is occurring slowly and constantly. How is this like a cake? The Principle of Uniformitarianism is like a layer cake because people basically make cakes the same way every time.

The assumption of a constant. However pi is not an assumption but something that can be determined using geometry and mathematical proofs.
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
