Comment Excessive CPU usage in OS X 10.4? (Score 1) 554

I've been using the betas and RCs for a while now, and I've noticed that for some reason, Firefox is using an unusual amount of CPU cycles. When a Firefox window is open, FF uses 15-20% CPU (on my SantaRosa 2GHz MacBook Pro) continuously. When the window is closed (but FF is still running) the usage drops down to 1-2% I don't think this happened with FF2. Any idea why this might be so, and if there are any workarounds?

The small size of nanoscale crystals results in the conversion of this energy into electrons instead of heat. Solar cells made of silicon nanocrystals could theoretically reach more than 40% efficiency, compared to 20% efficiency of the best conventional silicon solar cells.
An article in the Tech Review goes into more detail."

Fifty years ago this month Hugh Everett III published his paper proposing a "relative-state formulation of quantum mechanics" — the idea subsequently described as the 'many worlds' or 'multiverse' interpretation. Its impact on science and culture continues. In celebration, a science fiction special edition of Nature on 5 July 2007 explores the symbiosis of science and sf, as exemplified by Everett's hypothesis, its birth, evolution, champions and opponents, in biology, physics, literature and beyond.
Read the excellent selection of articles (and quite a few related scientific papers) from this special edition of the Nature magazine here."
