Carbon For Archimedes (2)

Carbon For Archimedes (2)

And one year after it was told us how to produce carbon spheres in relative abundance (at least, enough to buy a decent quantity from your laboratory chemical supplier), along comes Sumio Iijima telling us how to make cylinders.

You may recognize the famous Russian composer Modest Mussorgsky, whose best known work is “Pictures at an Exhibition”.  But the pictures that follow are from a totally different exhibition, that of the Association for Science Education Annual Conference 2011, held at the University of Reading from 5th to 8th January.
