wolven7'Parallel universes make quantum sense:
'If you think of yourself as unique, think again. The days when physicists could ignore the concept of parallel universes may have come to an end. If that doesn't send a shudder down your spine, think of it this way: our world is just one of many. You are just one version of many.
'David Deutsch at the University of Oxford and colleagues have shown that key equations of quantum mechanics arise from the mathematics of parallel universes. "This work will go down as one of the most important developments in the history of science," says Andy Albrecht, a physicist at the University of California at Davis. In one parallel universe, at least, it will - whether it does in our one remains to be seen.
'The "many worlds" interpretation of quantum mechanics was proposed 50 years ago by Hugh Everett, a graduate student at Princeton University.'
A bit sensationalist, but the point is clear. Also, you are as unique as any number in an infinitely diverse set can be.
'NASA resurrects cancelled black hole mission:
'NASA has revived a mission to study black holes after cancelling it in 2006 due to budget constraints.
'The Nuclear Spectroscopic Telescope Array (NuSTAR), now scheduled for launch in 2011, will observe the cosmos in the poorly studied high-energy X-ray band. It is part of NASA's Small Explorer class of missions, which have a cost cap of $105 million, not including launch costs.
'NuSTAR will carry out a census of black holes of all sizes, from small ones weighing a few times the mass of the Sun to 'supermassive' black holes weighing millions or billions of Suns.'
Awesome. Scarier, to me, than parallel worlds, though...
Yeah.
How's your Saturday?

Date: 2007-09-23 03:12 pm (UTC)I was thinking, yesterday, about the linguistics (I kind of like that typo; I misspelled it "linguistices," and my head pronounced it "linguistisees" which is...yeah. Neat) of "Nothing" and "Everything:" The way that Everything is, in the mind, a really big thing, but that Nothing is either considered really small OR really big, because Nothing is, ironically, something we deal with instances of quite often. An instance of Nothing is tiny, while the concept of Nothing and the concept of Everything are both gigantic. And we don't have a tiny Everything, because even the few times when we deal with an instance of "Everything" it's usually big because it's "all of X," where "none of X" is small no matter how large X would have been. A dearth of Elephants, for instance, is still tiny.
Oddments.
Black holes, of course, are a tiny "Whole Lot," but that's an entirely nonlinguistic issue.

Date: 2007-09-27 02:08 pm (UTC)Sunday was helping Grant move, followed by D&D, followed by collapsing into bed at 7. It wasn't 12 hours straight, there were a handful of interruptions, but it was still very nice.
Coming tomorrow?
