Are you feeling scatterbrained today? Our weather forecast includes "scattered showers" (after four weeks of complete dryness and high heat). The dots and stripes on my tie honor the birthday of experimental physicist Clifford Shull (1915-2001). He won the Nobel Prize in Physics in 1994 for his research into neutron scattering and neutron diffraction -- basically, how neutrons interact with atoms and with other subatomic particles, where tracking their motion and energies reveals details about events near the limit for existence of ultimately-tiny things.
