  2. Seeing Science with Animation Telling a Story Capturing a Moment

  3. “Speeding Young Star”(The Moment) Goodman & Arce 2004 Figure 1 PV Ceph: The Story

  4. Good Stories(a.k.a.) “Visual Explanations” Evolutionof processes in time “Tracking” Findingkey moments Ill Studying processes where non-sequential frames are critically related e.g. 2-D slices of 3-D data, shown in time Animation for Good, and for Ill

  5. Numerical Simulation of Star Formation (Good) • MHD turbulence gives “t=0” conditions; Jeans mass=1 Msun • 50 Msun, 0.38 pc, navg=3 x 105 ptcls/cc • forms ~50 objects • T=10 K • SPH, no B or L, G • movie=1.4 free-fall times Bate, Bonnell & Bromm 2002 (UKAFF)

  6. Good Stories(a.k.a.) “Visual Explanations” Evolutionof processes in time “Tracking” Findingkey moments Ill Studying processes where non-sequential frames are critically related e.g. 2-D slices of 3-D data, shown in time Animation for Good & Ill

  7. COMPLETE/FCRAO W(13CO) Barnard’s Perseus Animation frames are velocity “slices,” NOT time steps (Ill)
