Nanotube Forests and Diatoms

Compare these images of carbon nanotube arrays, created by John Hart, of the University of Michigan, with the Ernst Haeckel drawings. Last year I covered a Scientific American magazine article on the 2008 BioScapes Photo Competition: story and photos, and the Nikon Small World Photomicrography competition. There are more amazing scanning electron microscope images, including nanotubes, here.

And, in the latest Scientific American on line there's a scanning electron microscope slide show by University of Georgia digital media professor, Michael Oliveri.

For another view of things small see

The 4th plate from Ernst Haeckel's Kunstformen der Natur (1904), depicting diatoms (Diatomea).

Here's a gratuitous image, possibly tube-shaped like the nanotubes, from my sinusoidal grids project:
