Strong Points: Great images
Weak Points: Needs better educational content
If mathematics is the universal language of science, electron microscopy must be the universal medium of the nanoworld. It is difficult to quantitate the value of an image to convey information about tiny structures. The Scanning Electron Microscopy site, hosted at Iowa State University, focuses—pun intended—mostly on images in its beautiful Picture Library. These include pictures in categories of Insects, Biological, Submitted Samples, Materials, Etcetra, and Food. A section on Pseudocolor shows how color can be used to liven up an image. Longtime readers of this column know what a sucker I am for pictures, and the ones here certainly are worthy of mention. Two other components of the site—What is SEM and How Does the SEM Work—are pretty pedestrian.
