Sometimes I listen to podcasts while doing mundane activities like washing dishes. Some time ago I caught Lisa Randall, a theoretical physicist at Harvard, talking to Krista Tippet on the On Being podcast.

“Most of the time we all behave as if what’s here on Earth is all there is.”

Listening to the conversation I envisioned her creating models similar to a gardener creating terrariums or bonsai plants.

“Simplicity isn’t always beautiful, and sometimes complex things are more interesting.”
