FRAGMENT FROM NATURE for this and next weekend focuses in a remarkable essay authored by two MSc students and their advisors who made observations on the jamming of material like sand in a funnel, and derived conclusions about relativity and black holes from it. Johannes Kepler’s famous 1610 essay in the six sided snowflake similarly extrapolated from a snowflake to material packing. It is in the honored tradition of serious people making observations on things like peacock feathers, beetle casings and butterfly wing scales and deriving conclusions about optics from them.
