Ok, we all know about h-index nowadays. Here is another index, which, according to the authors of this paper [1], published in Science, measures individual scientific impact. This is now Q-index, which not only predicts h-index and cumulative citations, but also prizes, according to the abstract.
This paper (as many many others by Albert-László Barabási) is a total fun to read. It is also important that now we have more than one measure. It would be even more wonderful to have also A-index, B-index, etc… so that those that are so desperate to have a numerical metric to evaluate scientific output of a researcher would be finally lost among multiple and not obvious choices.
