Works fine in Safari 3/4, i'd imagine chrome should be fine too as its also using webkit. Albeit with a different javascript engine.

Really the lagging IE bit may be more along the lines of "we are a tech site, our visitors most likely can use a decent browser that adheres to some semblance of standards". I admit though I don't use IE 7/8 so I can't speak to how well or not those browsers work. Too lazy to fire up vmware.

Someone needs to clue science writers in on the difference between energy and power. Power has that whole time component that tends to let us know the actual energy needs.

Just as a personal experience. About 2 months ago I had an accident on my motorcycle (rain+sand+corner = helmet on pavement). I survived fine, but the very last thing I remember was trying to brake to a stop with both tires skidding over the pavement.

The very next thing I could remember is why is there a cat on my chest and more importantly where am I? As it turns out I was fully cogent during this time, called my buddy multiple times etc... I had lost memory formation entirely and repeated the same questions over and over.

While this incident was quite honestly minor in scope, it really helped me to understand at a personal level that consciousness really seems to just be a higher order brain function. All I remember in the time in between is.... black, no other way to describe it. I am hoping we can prove consiousness first before we go insane trying to figure out if machines are conscious too. Let alone have "souls".

I know anecdotal personal experience isn't worth a whole lot as proof, but it doesn't seem to take much to lose the ability to exist.
