This is how it works
Both the Intelligence and conventional rackets deflect backward somewhat upon ball impact. With a conventional racket, the ball leaves the stringbed before the racket returns to its normal position. The Intelligence, with its active electronic microchip system, creates a counterforce that deflects the racket slightly forward as the ball leaves the stringbed. The net effect is a 50 percent reduction in vibration.

Re:Propellantless Mass Space Propulsion Engine
They laughed at Newton. They laughed at Einstein. But they also laughed at Bozo the Clown.
Real scientists always publish and share their work. When someone says they have something brand new that no one has ever thought of before, and claims it will change the world, but won't tell you what it is, they are a fraud 99.9% of the time. That's what the bullshit detector picked up on.
And why does the link on his site about flying saucer propulsion point to a Popular Mechanics article about a 40 year old US Military project? -

Re:News To Me
You hit the nail on the head.
The BSA/RIAA/MPAA don't know from pirates.
Real pirates waylay you on the high seas and take your property on threat of death. And they might rape you to. That's a little bit different than little Johnny violating copyright by copying the "Lion King". -
Concrete Submarine
There has even been serious military planning for concrete submarines. Since concrete is very strong under pressure, such subs can sink to enormous depths and lurk on the sea bottom, looking like a rock to enemy sonar. Steel subs can only go down about half a mile.

How about......a concrete submarine?
There was a whole article about this in the New Scientist a couple of months ago, it's not on their site but I seem to recall it mentioned concrete planes too...

PM Article.
Popular Mechanics ran something to this effect sometime ago. It can be found online here.
I can just imagine it now, getting spam that reads: "Do you weigh over 200lbs? Well we have the solution for you! Loose over 4lbs INSTANTLY! Thats right, INSTANTLY! NO gimmicks, NO drugs, just pure science! Only $600,000! Act Now!" -
Re:life and death issue??
"this is a life and death issue"
These weenies don't know from real pirates. real pirates shoot and kill people and take their physical property.
A long sight different than some kid who makes a copy of a song.
I think it's a shame that the word " pirate " has been so trivialized. Sort of like happened when the media started using the term "hacker".

A few interesting articles...Just looking around online, I was able to find a bit more info about the subject. One good read (well, actually a number of good reads) I found was from the Howard Hughes Medical Institute's 2000 Annual Report. There are a number of articles that are worth checking out, but I would recommend the one entitled "Brain-Wiring Receptor Shows Extraordinary Diversity." Here is a brief quote:
Researchers have identified a new axon guidance receptor found in the tips of growing neurons that can exist in more than 38,000 slightly different forms. The unprecedented diversity of proteins derived from this single gene may offer an important hint that a fundamental code directs the precise wiring of trillions of neurons in the brain...
Also, an interesting, abet rather short, article from Popular Mechanics tells how researchers were able to actually "see" neurons changing at the synapse between two of the tens of million of nerve cells in the brain of a rat. -
Re:Dude, wider IS better!
There's a reason why tall, narrow SUVs roll over all the time, and why Corvettes never do. Can you guess what that reason is?
Ah, I see. So the Corvette is by far the most likely of all of these vehicles to roll over, right?
- Hummer: 86.5 inches
- Excursion: 79.9 inches
- Suburban: 78.8 inches
- Expedition: 78.6 inches
- CART/IRL cars: 78.5 inches
- Park Avenue: 74.7 inches
- 5th-gen Corvette: 73.6 inches
Hint: it's not the width, it's the ratio of CG height to width. Wider is not *always* better...

NOT the Jetsons...
There was an article in Popular Mechanics a while back that held up the Jetsons as an example of sci-fi predicting future technology trends.
I had to laugh -- I remember an episode where George flies across town in his personal jet car to mail a letter. How much more wrong could you get predictions of email?
Of course, the same article also praised Star trek, which also often missed the technology prediction boat. The article is here As for literature, I'd go with Asimov as having the best predictions! -
Re:Fear the Backhoe
Yeah, you could do that, but I think that a possibility that rarely gets talked about is that of an EMP bomb. A few of these in strategic locations (I'm thinking Silicon Valley, DC, etc.) would not only thrash the Net by ruining colocation facilities, routers, etc., but the economic implications would be unbelievable. Anyone touting a "Digital Pearl Harbor" ought to be aware of just how fragile our technology really is.

Thats not surprising at all...
I guess that anyone that's heard of Moore's law doesn't be surprised by this. In 1971 Moore published his Law that describes the performance increase for semiconductors and was estimated as an 18 month doubling. You can see a fine graph about this here.
And a fast calculation (based on a 2GHz intel P4 :):
6 years = 72 months
72/18=4
and 2^4=16GHz
And 2.1 GHz will give 19.4GHz, which I think they will release before new year or so...
It is possible that the 18 months would be slightly different, like 20 months, but clearly this trend has continued with little change. But remember that computer performance is strongly influenced by the semiconductor trend but need not be exactly identical. -
DSL and Cable soonDSL was a pain to set up, but, once I had it installed, it has been working GREAT for almost a year now. And its Pacbell as well. Surprise, surprise.
My previous place had Covad DSL, and that was fairly reliable as well, though the speed of that connection was not nearly as fast.
I think that as cable companies and phone companies upgrade/update their infrastructure, we'll see more people get DSL or Cable. I think it will be something like the Cable service. You'll not really have much of a choice other than to use AT&T At Home or Pacbell DSL (here on the west coast).
Competition can be a bad thing, ie: look at the energy situation here. But if I had 2 choices, that would be better than just one. Kinda like using either Satelitte or Cable. Both cost about the same.........
Dvorak's statements could be akin to this article 10 years from now....

Broken pictures; here's a better link
Try http://popularmechanics.com/popmech/sci/1950STROM
. html. That appears to be where the MIT copy is from, anyway (do a "view source" and look for "saved from url").The MIT copy has URLs for the images that look like this: src="MIRACLES OF THE NEXT FIFTY YEARS_files/1950STROE.jpeg". Ick -- spaces aren't legal in URLs. Escaping them as %20 works if you want to look at them individually, but the browser won't be able to show them inline.

alternate theory: gas powered shoesAn alternate theory that seems plausible is that Ginger is related to the 'gas powered shoes' developed by Roman Kunikov, an aeronautical engineer working at a Russian research institute.
They received a fair bit of press in the middle of last year, following an AP report that they would propel the wearer to speeds of up to 25 mph using a mechanism similar to footwear-mounted pogo sticks with internal combustion engines (!).
Some selected articles on this invention can be found at: http://popularmechanics.com/perl/tw_display.pl?id

More info about the levitation device
This is a popmech story about the device. Also in their latest issue is a larger story about a machine that can cancle the gravity vector completely all the way to space. Now, I am as skeptacle as next guy, but if this is true, it will REVOLUTIONIZE the space program. You could get into space with a cylinder of compressed gas!

Re:Commercial explorationLook at the cover of the current issue of Popular Mechanics. Above "MOON VACATIONS" is a lunar hotel with the Mariott logo.
For a more thorough essay on starting to commercially explore space, see "Rockets, Redheads, and Revolution" by James P. Hogan. One of the chatty chapters between stories is about why government has stifled space exploration, merely by being the only entity doing so. (It's probably in the "Science Fiction" section of your library/bookstore)

Re:It will eventually happen
Predictions like those and These make some sense at the time based on current technology. They were often based on fantasy in their day. Personal robots didn't catch on due to many impractalities, starting with keeping them powered. The "Pushbutton Society" they predicted in the 50s and so forth have not been wholly realised, but some of the technologies have. PCs are also a part of the equation left out in the 50s, but they developed anyways!
While the conversion of ALL books seems ludicrious, MOST of them can be translated to machine code. A great deal of the books out there can be OCR-ed and formatted into a usable format and some stories are only available online.
Besides, the prediction of all books being available online are more limited by publishers than technology. Until you have some sort of cross-platform (fie on Microsoft!) book-reading solution where payments for material are made, you won't see everything online. This is more societal than anything else.

Another site predicting the future...
Popular Mechanics is doing something similar to this. Here's an article called "Miracles of the next 50 years" This is really cool.. the article seems pretty level headed too, like it doesn't go into detail about "flying cars" or teleportation. Think reality, guys

InductrackLawrence Livermore's "Inductrack" seems much more feasible then winged trains. It fits onto current right-of-ways, no exotic technologies are required (no super magnets, etc.), and is quieter then existing vehicles. It's rails can be made of low-cost materials and the levitation system is conventional magnets in arrays. The levitation effect comes into play at speeds over 5 kph and improves up to 500 kph so a train simply rolls up to speed (a fast walk) and then glides from there. Best yet it's a passive effect inherent in the design - power failures don't cause the train to suddenly drop onto the rails (a problem with the Japanese and German designs.)

Re:Why the hell would the Chinese government do thUnless this was the first step in some kind of long-term plan (Mars anyone?)
China will make some accomplishment, like building a small Moon base, and the US will suddenly wake up. America will put its money into Mars, and as a result, save the US from stagnation.
Then the US will look back and remember that it was China that poked America on the shoulder just before it dozed off during the final exam, and suddenly decide to be helpful to China.
Hey, I can hope :)

Re:New military branch: The USCF (US Cyber Force).Actually I recall an article in Popular Mechanics about this. And it is under the USAF (Though the place is called the AFIWC = Air Force Information Warfare Center). Maybe they got the job because of the USAF's extensive use of high technology for US Space Command? Anyway, the article was worth a read (IMHO).
And like magic a search of PM's site brings up the article
-
What happens when...
The US decides that they don't want so many people to be hiding their money here and they have a little police action against Nauru. I mean literally just send in a couple hundred marines and helicopters and take the place over, given the current ability of us presidents to use military force without congressional or UN (haha) approval I really don't think this is so farfeched. I'm all for undermining the us tax structure but I'm worried that if all of these tax shelters are used by mobsters then the rest of us common sensible self deterministic anarchists are never going to get to use them properly. Here is my suggestion, set up the pr functions on the island, get a big international data cable strung out there, then sink a big concrete submarine down there and keep all the data and money underwater, where a bunch of marines and helicopters can't just waltz in and get it. Then this would be a lot more like Cryptonomicon. and lord knows we need the world to be a lot more like that.
