the thing is, there's no such thing as a 'ray' of light, as all light beams have some thickness, even lasers. so even if you hit the middle of said flat lens, you can still get the beam to converge (or 'focus') for a while because the light that doesn't hit it right in the middle will bend toward the middle. if you distribute the index of refraction the other way, you can make a flat diverging lens as well.
even better is to set up your computer to route requests that are trying to go to www.nytimes.com to the archive instead. the ip of archive.nytimes.com is 199.239.136.212
windows users can find a file named hosts (no extension) under system32/drivers/etc and add the following line to automatically go to archive.nytimes.com instead of www.nytimes.com:
199.239.136.212 www.nytimes.com
personally, i had trouble with the article saying that all "normal" (which sounded like positive refractive index) lenses are curved.
it was my understanding that a flat lens can be just as functional as a curved lens as long as the index of refraction is correctly distributed. what matters is path length difference, not simply length difference, and path length depends on index of refraction.
of course they could have meant "normal" as in simply cut from a chunk of material that was the same throughout, in which case a distributed refractive index falls out of the normal category . . .

yeah i remember back in elementary school we were on some kind of sciencey field trip and they had two big metal balls that we could see the electricity going between, then it smelled bad and they told us that it had burnt the air and made ozone . . . that's so cool.
that would be why i have the memory card for the n64. my games let me copy stuff from the cartridge to the card and then i can load it up on a friend's system or something.
i've often thought that it's a waste to use a whole cd for 100 or so meg of data or 15 or so minutes of audio . . . it'd be nice if this got widely used!
if you use windows, add the following line to the hosts file found in drivers\etc under system32:
199.239.136.212 www.nytimes.com
i'm not sure how often the ip address of archive.nytimes.com changes, but this will work as long as www.nytimes.com and archive.nytimes.com share the same directory structure and the ip address of the archive stays the same . . .
i have to remember what i told my 12-year-old self:
never put salt in your eyes . . . never put salt in your eyes . . . never put salt in your eyes . . . never put salt in your eyes . . . put salt in your eyes . . . always put salt in your eyes . . . AAAAAUUUUUGH!!!!!!

maybe you live in a different country than i do, but every time i bought them, they said 'model rocket engines' on the package. also, your link to the definition of engine, while it shows that the word can be used to mean something else, also shows that it applies here. of course by the definition of motor, it could apply here as well, but in all the places i've lived, motor has always been electric, and engine is pretty much everything else.
I understand that we have to be careful in these post 9/11 times [ . . . ]
why is it that so many people believe that we need to be any more careful now than we needed to be a year and a half ago? i most certainly say that we do not!
it was great to see the way the nation reacted by coming together and helping each other out in the days following the attack, but everything more recent than about two weeks after has just been getting worse. we have been dishonoring the memories of those who lost their lives for no good reason by slowly whittling away the freedoms that made the usa something we could be proud of, and by breeding fears of another attack.
the plain simple truth is: terrorism most likely will not affect you! certainly the entire country mourns for the losses families suffered, but how many people were really directly effected by either knowing well someone who died, or witnessing the event? i think that it's well and good for americans to be upset by such events, and to help each other out when they happen, but until it happens again, remember that most of the threats we're supposed to be cowering in fear over aren't really that bad, don't affect a very large area, and are very unlikely to affect you directly.

no, i didn't read the article, but it conjures up images in my mind something to the effect of "EXIT NOW!!! Some really great thing that will enlarge your penis and automatically file your taxes for you is here for you to purchase!" (which is of course, presented in annoying flash)
most people don't care until they find out that they can't do what they want with the media they bought.
i'd guess most people who buy dvds buy dvds for the region they live in, which is the same region their dvd players are set up for. they don't look at the packaging other then to see if it's widescreen or not because they don't know (and don't need to know) that there are dvd players that don't play it.
crippled cds on the other hand, are more likely to not play in a randomly selected player than dvds are -- i think we've reached a point where all but the most clueless have realized that their computer did NOT come with a retractable cup-holder.
Or what if XP dies. Then I have no Win98. I'd like to see an upgrade feature that let's me keep my existing Win98 installation as WELL as upgrade Windows 98 to XP at the same time.
not that anybody on slashdot actually wants to have windows 98 and xp on one computer at the same, but maybe people are asking you how to do it so they can use whatever software they bought 10 years ago that doesn't work on xp. if so, you can install 98 and xp and force them to play nice together . . .
here's how
if your only problem is that you couldn't access a track name database, then why don't you just read the titles from the cd case and enter them yourself? yes i agree it is annoying to have to do that, but it's been my experience that you can't trust whoever enters titles into these databases to get it right all the time anyway. and even if cd-n-go (i've enver used it) won't let you change the track names if it can't find it on freedb, you can always change filenames and id3 tags later!
