Carbon nanotubes!

Carbon nanotubes are the hottest topic in physics, according to a new way of ranking the popularity of different scientific fields. Nanowires are second, followed by quantum dots, fullerenes, giant magnetoresistance, M-theory and quantum computation. The new ranking has been developed by Michael Banks, a PhD student at the Max Planck Institute for Solid-State Physics in Stuttgart, Germany. He thinks the index could be a quick and simple way of determining the most important subject areas in physics and could even help graduate students choose which field to do their PhD in (physics/0604216).
The new index is based on the "Hirsch index", which was devised last year by Jorge Hirsch of the University of California at San Diego as a way of quantifying the performance of individual scientists. Hirsch's h-index is derived from the number of times that papers by a particular scientist are cited. A scientist with an h-index of 10, say, will have published 10 papers that have received at least 10 citations each. The best researchers should therefore have the highest h-indexes.
