I don't see any reason why the laser has to strike the phosphor at anything close to a perpendicular alignment.
The angle at which the beam strikes the phosphor would determine the shape of the intersecting region, which may be difficult to correct for. However, a small mirror near each "pixel" that redirected the beam straight at the phosphor would likely correct the situation without taking up too much extra space.
further, the shorter the strand of DNA, the fewer chances exist for error when the strand is duplicated. All else being equal, Short DNA may logically be a defense against cancers and other genetic diseases.
this is true (conficker, for example, patched the very vulnerability that it exploited to gain access). However, that doesn't mean that this particular chunk of malware should be assumed to be safe. Personally, I would err on the side of not trusting anything that changes the behavior of my computer without my knowledge of permission.
the best thing a school can teach a kid is how to learn. Teaching a kid to "use a computer" is not nearly as valuable as teaching a kid how to learn how to use a computer. A kid who was taught how to use 3 very specific applications on exactly 1 operating system is going to be in deep trouble (or at the very least a nuisance to his IT department) when he starts a job that uses a custom application to do 90% of his work. Trust me on this one, I work in that IT department
by the time they're done with school, it won't matter what OS they used, they will have all changed so drastically. We had an Apple II in my classroom as a child, which OS would you say it prepared me for?
change all your passwords to the same dummy password, then fill out your application with said dummy password. After compromising your dummy password, adhere to the sites' ToS by changing it (back). You didn't falsify your application, the information just became obsolete. I'm sure they don't require you to submit an addendum any time any piece of information on you application is rendered false.... right?
I think that the game industry includes their "extras" in more of an effort to reduce second-hand sales, in which the store makes a ton of profit while screwing the developers and consumers. That's why you'll see things like one-time downloadable content codes packaged with new games. The video game industry has done a pretty good job of thwarting piracy at a technical level. Yes, you can play pirated games if you void your warranty, but the mainstream players aren't going to do that (especially when it's such a huge risk on platforms like the XBox 360)
Microbes are found in almost every habitat present in nature.... it is very likely that even though we ingest huge ammounts of disgusting fast food this would not make your body an environment hostile enough to kill any given microbe.
the first part of that is true, microbes are found in nearly every extreme environment known to us. However, the same microbes are not found in all (and in most cases even > 1) of these environments, and a great number of them can't survive "normal" conditions. It is extremely likely (though not guaranteed) that a microbe that is suited to survive frozen for that amount of time would be killed by the temperature, PH balance, etc. of the human body
"furthers evolution"
there is no furthering evolution, there are just different pressures.
Actually, the point I was going for is that it does not "work against" evolution, because evolution is merely the process of reaction to selective forces, so I'll agree with you that I may have mis-worded what I was trying to say.
Why is genetic diversity such an issue in a world where genetics can be altures invitro?
it wouldn't be, but that's not the situation. We are not altering genetics, we are selecting which embryo to implant based on the embryos' genetics. If this is done enough times, certain "unfavorable" alleles may get completely erased from our gene pool. In that case, this process is unable to bring those traits back
There isn't a lot of evolutionary need to hair or eye color anymore, if ever.
While the physical characteristics may not be necessary, sometimes genes can interact with each other in complex and unforeseeable ways. For instance, people who carry the sickle-cell gene are immune to malaria. It is not entirely unimaginable that a disease could exist that kills everyone except people with brown hair and brown eyes (perhaps a bacteria that is sensitive to high levels of melanin). If that disease strikes a population that has artificially selected against brown hair and brown eyes, the effect would be devastating
I think what you meant is that it works against the process of natural selection. Any selective process, including this type of artificial selection, furthers evolution, but in this case "fit to survive" means "able to pass the screening process." The example you chose, while still a very real concern, less to do with evolution than with genetic diversity, which, as you imply, is very important to the survival of the species should our environment change violently
that's why I bought 10 pieces of hardware before connecting my computer in my home office to the internet. I think the issue ends up being scalability vs. robustness
and objects can only be one of 3 colors, can only have one of 2 temperatures, and can coexist in the same place as another object provided the color and/or temperature differs

Yeah. No operating system known to man prevents you from "writing software badly".

He sounds like the kind of guy that shows up with a sawed-off shotgun one day and pulps the office.
nah, probably more the type to intentionally introduce a rounding error that nobody would ever notice. They did it in Superman III
I just wish the summary were better. The title and summary use Depression and Manic Depression interchangeably, which is just dead wrong.

"beam of invisible light" != "invisible beam of light". I know I'm splitting hairs, but the light is not invisible, the beam is
Not that this is a sustainable patent (it seems pretty obvious to anyone skilled in the art).
I wish that were true, but it's not those guys we have have to worry about.
