James Holton has a great little movie showing how electron density
changes with decreasing resolution: http://ucxray.berkeley.edu/~jamesh/movies/resolution.mpeg

Hi all-
I recall seeing a long time ago a figure which showed the
progressive improvement of electron density as one increases
resolution, say from 6 to 3.5 to 2A. I believe I've seen two
versions- one a larger scale pic showing the ability to model side
chains of alpha helices at higher resolutions and the other a
simpler graphic of a tyrosine aromatic ring showing the electron
density hole in the middle of the ring once near atomic resolution
maps are obtained. Does anyone have, in their teaching notes or a
textbook or presentation, a graphic which displays this? I need it
for a talk this weekend and Google searches have come up blank. If
all else fails, I can generate it myself...(lazy sigh)
Thanks in advance-
Brad
