It will happen sooner than your estimate
Consider the basic argument that resource production/depletion tends to follow a bell-shaped curve. See this page (in particular and the whole site in general). Now that data is 5 years and a relevant war out of date, but the general concept is still valid.
Scientific American has a followup that is only 2 years out of date and it puts the peak between 2004 and 2008. I haven't seen any huge discoveries of new oil fields in the last two years so ... -
Re:Probably a U-2 crash
Think of it this way. If an alien landed today, and shook hands with the locals, would you believe the media? If not, you are severely biased the other way.
That this hasn't already happened is probably the reason most people are skeptical. Check out Ian Crawford's "Where Are They?", he makes some interesting points regarding the Fermi Paradox, Drake Equation, etc...
excerp: ...the first technological civilization with the ability and the inclination to colonize the galaxy could have done so before any competitors even had a chance to evolve. In principle, this could have happened billions of years ago, when Earth was inhabited solely by microorganisms and was wide open to interference from outside. Yet no physical artifact, no chemical traces, no obvious biological influence indicates that it has ever been intruded upon. -
Pizeo or artificial muscles dude!
Scientific American had an interesting article (the begining of which is reproduced here. Basically, two charged plates are on either side of an elastic material. Provide a current, and it compresses... compress it and it provides current! Apparently the US Army is interested in turning the tech into portable generators for their 'soldiers of the future'.
Pizeoelectric devices would work the same way; deform them and they generate electricity.
Solid-state approaches also would make production easier... none of it has to be waterproof. You could probably even convert a good pair of running shoes no problem. -

This example is a bit stupid - what stops a computer program from filtering out everything of the wavy background by just eliminating everything non-black? There seems to be so much contrast in the image that it would be a really trivial job.

They do a very poor job catching drug usersThis is somewhat interesting. But the atheletes don't need exotic new technologies when they can easily get away with using performance enhancing drugs. The two most prominent performance enchancing drugs which can't be tested for are EPO and HGH. Here's a Scientific American article.
As this article states, the cheaters are way ahead of the drug testers. Notice that they have a quote from the anonymous Olympic Committeeman. "If this were a basketball game, we'd be behind about 98 to 2." I have even read that it is widely believed that rich countries do better in the Olympics primarily because they can afford better masking technologies.

Re:Fact or fiction?
Here's a link to a Sci. Am. article on super-absorbing stuff. At the bottom is a picture of water molecules associating with the polymer chain.
It'll help to remember that the water/polymer association is just that: an association. This isn't a 1:1 bonding situation, so the carboxyl groups can attract more than one water molecule.

...and then a moderator said....
Here's a link. You could have used Scientific American's search feature to find it. Or how about the abstract here. Perhaps the original poster assumed too much by assuming that you could remember back a whole year and a half to when the study was published.

What's new about this discovery
This SciAm article describes three categories of ferromagnetic materials. The first two are ferromagnetic alloys (which are what make up MRAMs and other current ferromagnetic tech), and ferromagnetic semiconductors. This team has discovered the first room-temperature (or higher) ferromagnetic semiconducting material, hence opening the way for spin switching and computing.
-
Explanation...As another poster mentioned earlier, this type of material has been creted earlier, but had to be kept at a temperature below -101 deg Celsius to function. A more detailed look at this field is available here.
This article (from feb 2003) mentions that one of the major obstacles is making it work at room temperature which now has been achieved. Apparently this is a huge breakthrough.

Re: computer for the poor?The simputer is not just hardware as you seem to assume, it's a whole interface and system, developed for use by people who have never used a computer before.
For example, it doesn't have a keyboard or mouse, and doesn't need you to know what one is.

Re:Eh?
Searching ScAm's Ask the Expert section, I found the following:
"Dragline silk [a kind of silk all spiders make] is a composite material comprised of two different proteins, each containing three types of regions with distinct properties. One of these forms an amorphous (noncrystalline) matrix that is stretchable, giving the silk elasticity. When an insect strikes the web, the stretching of the matrix enables the web to absorb the kinetic energy of the insects flight. Embedded in the amorphous portions of both proteins are two kinds of crystalline regions that toughen the silk. Although both kinds of crystalline regions are tightly pleated and resist stretching, one of them is rigid. It is thought that the pleats of the less rigid crystalline regions not only fit into the pleats in the rigid crystals but that they also interact with the amorphous areas in the proteins, thus anchoring the rigid crystals to the matrix. The resulting composite is strong, tough, and yet elastic." -
Eh?
Well, I've read the article. I've read Scientific American's version. I've read a few other ones google referenced. And I still haven't a fucking clue why silk is so strong.
Am I getting dumber, or are these science article getting more opaque?
"becuase of proteins with various properties" me arse. -
Re:Libraries should pay royalties?!
It's fair use. Letting other people borrow your copy of a copyrighted item. As long as you aren't making multiple copies, you can give that copy that you bought to other people. What is scary is this: No public access to online journals

M-Guide IssuesMoores Law is quite interesting, Scientific American has covered several interesting quandries that occur:
1) As Moore's Law goes further down the exponential path, errors will increase as well (specifically with hard drives)
2) The complexity of setting up chips
3) With technology updating so quickly, disposal of old PCs
The other point once made (although I can't find a link) was Moore's Law could arguably be perpetuating itself. Instead of looking at it as what is orginally was, an observation, many see Moores Law as a guide and judge the growth of the Industry--making it a goal companies strive to attain.
Just my 2 cents... -

Dude, that's embarassinly wrong.Train wreck? What a total crock from Keynote. here is a well researched article that's easy to read for you. Code Red and other Microsfot transmitted diseases have a destabilizing effect on root DNS, a weakness eveyone without a huge hosts file or cached lookups has. Keynote Systems has been rewareded for such whoring and you should dismiss such a silly statement from them.
No one is blaming these stupid worms for all their woes. Well, maybe a few airlines can gripe because their ticketing system is completely disabled. The worms are, however, exasperating the blackout's impact, and some have even implicated it as the blackout's root cause. Statements in the New York Times about non fuctioning alarm display sceens being the root cause of the blackout give those rumors weight. In any case, you are missing the point.
lots of people are (hopefully) going to be scrabbling for WindowsUpdate for patches which will also add to the bandwidth being consumed.
The God damn worm is consuming bandwith in just that manner. Thanks to Microsoft's brain dead distribution system, that bandwith consumption is nationwide. You can contrast that to free software distribution systems where it's easy to set up a local mirror and theyby reduce the amount of traffic needed by orders of magnitude. I've only got six machines or so, but my bandwith usage is down dramatically thanks to a local mirror. The same benifits can be had, but to a much larger extent, in an organization with hundreds or thousands of machines. Train wreck, yeah, that's about right. One track, all blocked up by broken shit. Hopefully, people are going to be scrambling to replace that M$ junk. How many times do you have to be burnt to learn?
Statements about lower TCO for M$ junk are equally flawed and embarassing when you factor in the costs of worms like this and weeks of lost business.

Nuclear Design & Fears
Reactor design article by Scientific American
Read that article in print before & it talked about using spheres to contain the nuclear fuel, like a giant gumball machine spitting out spent fuel balls. Discover or SciAm also had an article in the past year regarding cleanup of exisiting sites: apparently, the rules as they are now, or proposed, suggest people may actually want less radiation there than NATURALLY occurs! I also grew up watching "Silkwood" & reading about Chernobyl, so you're going to have the nuclear genie in people's heads for a long time. Also consider if we're producing enough nuclear engineers or not to keep the existing plants running, let alone expand nuclear use. I live not far from Kennedy Space Center, and there were people in this county opposing a new gas plant being built out by the swamplands; mix that with the blurbs about the proposed wind field in Martha's Vineyard: for ANY plant, there will be a "Not In My Backyard" issue. -

What I've seen about it talks about how they are moving to higher elevations on mountain ranges than they have been previously.
Here you go.
The other thing I've recently been reading about (not directly related to a warming climate) is that species of mosquitoes have been migrating due to global trade, riding in containers or whatever. -
Re: What is amazing is..
> It's always seemed odd to me that we are "up here" while apes and chimps are "down there" and other mammals kind of dribble down from that. Why nothing in-between?
Right now is sort of an anomaly in the family tree. For most of "human" history there were multiple species of "humans" living concurrently, and there were formerly many more species of ape alive at the same time too.
Also, the lack of in-between-ness is exaggerated by the nonlinearity of what has been going on in our species. If you compare the material culture of modern humans to that of chimps it looks like an unbridgeable gulf, but if you instead compare our material culture of 1,000, 10,000, 100,000, and 1,000,000 years ago to the current material culture of chimps, the gap really closes up.
It appears that a small difference in cognitive ability can make a huge difference when its results are allowed to accumulate over the millenia.
> It would be cool if there was some other species that slightly filled that gap bewteen us and the animals.
True, but arguably there already is. Take away the chimps and observe how wonderfully they fill the gap between ourselves and gorillas. Take away gorillas and observe how well they fill the gap between us+chimps and the other apes.
Our corner of the family tree is an interestingly dense bush as it is, and would be even more interesting if not for the extinctions over the past few million years.

Re:From a working horse owner's perspective
What you see, way too often, is a horse that looks pretty, but is completely screwed up in the head. And that's with traditional breeding (and I'm including the straw o'semen in the "traditional" category). I can only imagine the neurotic, unpredictable horses that will come from cloning the "best" show horses. They'll be useless for any actual work, probably won't be able to reproduce without assistance (already a problem today), and will be a danger to their rider and anyone nearby.
Some years ago, Scientific American had an article on the genetics of race horses. The thoroughbred racehorse has the best kept pedigree records of any form of livestock. The original founding stock was a mere 3 stallions and 40 mares; all racehorses alive today are descendants of those 43 horses, and every racehorse can have its pedigree traced back to the origin of the breed. Every racehorse is distantly or closely related to every other racehorse in the world. Racehorses must pass a "survival of the fittest" test, The Racecourse Test, and only the best horses are used for producing the next generation. If an expensive stallion proves to be a producer of poor stock, then he is banished from further breeding activity, despite his initial value; he is removed permanently from the breeding stock. Stallions of poor fertility are not persevered with, since they produce few offspring, and mare owners prefer to breed foals. Male thoroughbreds have a strong sex-drive and because of this, at least 90% of males are permanently excluded from procreating by castration. There are very few "genetic ailments" within the thoroughbred population, and weaklings are ruthlessly culled. One of the first use of cloning in racehorses is going to be its use to recover the genetic heritage of a gelding that proves to be a champion in its own right -- but only until that use demonstrates whether it's an effective way to recover the genetic line. -
Re:Amazing
It should be noted that research has been done into the whole bee/bug flying thing, and they have a pretty clear picture of how bugs fly. The bee one was poor science when it was done, using fixed-wing calculations on a moving-wing object. No less amazing, though, is all the stuff that has to be done to copy it, and the fact that it's controlled by something no bigger than, well, fly shit.
Here is an article about it. See how /. readers don't do that, a synopsis: Flies keep their wings at the edge of stall, which gives a boost to total lift; they rotate them at the end of the stroke, giving spin lift; and they do the upstroke through their own wake, recovering energy from the downstroke. Then they use a whole bunch of sensors to correct for turbulence, blah blah blah, meaning that a fruit fly has to do more thinking than the typical cubicle rat. -

I remember, you don't, NT not at fault
Your topic doesn't make sense, since I can't "not remember" an article that I might not have read.
Besides, maybe you didn't read this thread:
http://lists.insecure.org/lists/politech/2000/Aug/ 0027.html
Which actually partially references the article you mentioned, even though you cited a link that doesn't even work. (http://www.sciam.com/1998/1198issue/1198techbus2. html (nope, doesn't work even without the spaces))
I find it cute that NT crashes to its knees because a userland app made a division-by-zero (or buffer overflow) error. Which makes it at fault. -

Re:Just use a phased-array wireless switch. It's e
Please mod this parent down. Vivato claims to do wireless switching but this is simply a marketing term. They do interesting work on antennas, (from what I understand, similar to what is described in July's SciAm), but ~11Mbs on a single channel is an immutable law. What is more interesting as a solution for this WLAN problem is to set a Minimum Association Rate as described in this whitepaper.

Suggestions for Math and Physics
There are "for Dummies" books that cover many of the topics you've listed. I was never fond of them, but you may want to take a look at them.
The biggest problem when you're undertaking a self-study endeavour is that most books that are available are either
- Very specialized topics (What does pi mean?)
- Refresher-course books (Lots of problems, few explanations)
The specialized topics books - commonly reviewed in magazines such as Scientific American - are fun to read, but I'm not sure if they serve the purpose of what you're seeking.
How much of algebra do you know? If you can look through the table of contents of a textbook for Algebra I and II and are confident in all the topics, then I'd move on to geometry/trigonometry before calculus.
Also, keep in mind that conceptual physics texts are divided between algebra-based and calculus-based reasoning. Take whichever you're more comfortable with.
Some 'refresher-course' books that will come in handy with the conceptual books that others may suggest:
Schaum's Outlines
Research & Education Association's Problem Solvers series
CliffsNotes and SparkNotes -

Demystifying the Digital DivideFor those who read Scientific American, There was a great article about this sort of thing:
Demystifying the Digital Divide, The simple binary notion of technology haves and have-nots doesn't quite compute.
For much of the past decade, policy leaders and social scientists have grown increasingly concerned about a societal split between those with and those without access to computers and the Internet. The U.S. National Telecommunications and Information Administration popularized a term for this situation in the mid-1990s: the "digital divide." The phrase soon became used in an international context as well, to describe the status of information technology from country to country. Underlying disparities are real, both within and among countries. The Benton Foundation, which promotes the public-interest use of communications technology, reports that by late 2001, 80 percent of American families with annual household income greater than $75,000 were online, compared with 25 percent of the poorest U.S. families. Total home Internet access was 55 percent for whites, 31 percent for African-Americans and 32 percent for Hispanics. Looking at the international picture, in most African countries less than 1 percent of the population is online. Not surprisingly, such disparity correlates highly with other measures of social and economic inequality....continued at Scientific American Digital
