An Invisible Hand? - An Unexplained Effect During Solar Eclipses Casts Doubt on General Relativity
http://www.economist.com/science/displayStory.cfm?story_id=3104321

“ASSUME nothing” is a good motto in science. Even the humble pendulum may spring a surprise on you. In 1954 Maurice Allais, a French economist who would go on to win, in 1988, the Nobel prize in his subject, decided to observe and record the movements of a pendulum over a period of 30 days. Coincidentally, one of his observations took place during a solar eclipse. When the moon passed in front of the sun, the pendulum unexpectedly started moving a bit faster than it should have done. Since that first observation, the “Allais effect”, as it is now called, has confounded physicists. If the effect is real, it could indicate a hitherto unperceived flaw in General Relativity—the current explanation of how gravity works. That would be a bombshell—and an ironic one, since it was observations taken during a solar eclipse (of the way that light is bent when it passes close to the sun) which established General Relativity in the first place. So attempts to duplicate Dr Allais's observation are important. However, they have had mixed success, leading sceptics to question whether there was anything to be explained. Now Chris Duif, a researcher at the Delft University of Technology, in the Netherlands, has reviewed the evidence. According to a paper he has just posted on arXiv.org, an online publication archive, the effect is real, unexplained, and could be linked to another anomaly involving a pair of American spacecraft.

Apparently, the the invisible coat is yesterday's technology, and its inventor is hard at work focusing on building the invisible wall. As with the cloak, this works just by projecting an image onto the wall of what one would see if the wall weren't there. His goal is to make it someone in a room that had no outside windows, could look and see what was going on outside. A simple suggestion: simply installing windows seems like a perfectly reasonable solution in most cases where this situation exists.

The NYT is reporting that AOL is providing software to customers to block pop-ups. The sheer number of ironies in this article is simply delicious, and renders further comment unnecessary: 1) "AOL pioneered the often annoying but effective pop-up format" 2) "10 percent of its users had chosen not to receive pop-ups from AOL's own service, an option that has been harder to find than the new blocking software." Hard to find? Almost impossible. 3) "the number of sites that will accept pop-ups is increasing, including ever more sites owned by AOL Time Warner like Mapquest and CNN.com."

Searching the Invisible Tabs
http ://searchenginewatch.com/searchday/article.php/3115131

Tired of wading through thousands -- possibly millions -- of results to your Web searches? How would it be if search engines offered lists of category tabs -- so you could confine your search to relevant Web sites? Too restrictive, too cumbersome (after all, how many categories would there need to be)? Well then, how about invisible tabs -- behind-the-scenes functions that would automatically categorize your query and deliver results within that category? AskJeeves and others already do it to a degree. Example: Test AskJeeves against Google for "pictures of DNA." AskJeeves delivers images; Google offers a list of URLs. "It's not rocket science to see your query and decide that it makes sense to push the invisible image tab for you. But the change it produces, and perceived relevance to me, is dramatic," says SearchEngineWatch.com editor Danny Sullivan. To avoid frustrating searchers by, say, returning shopping lists instead product reviews, the search engine might come back with questions formatted as listings: "What would you like to do? Show me prices for this product from merchants across the Web; Show me product reviews from across the Web; Show me general matching content from across the Web."

IIP 1.1.0 (stable) is released. In this version the installation for Unix is enhanced, entropy generation is improved and a few bugs are fixed. See the CHANGELOG file for the full list. Although this is not a mandatory upgrade, you are advised to update anyway. The installation can be done on top of the previous version, but you will have to shut IIP down first to release locked files. Public relays should use the new node.ref, it contains more stable nodes. We hope you enjoy the newest release, and please report bugs and suggestions to iip@invisiblenet.net, or on the IIP mailing list. Download IIP: http://www.invisiblenet.net/iip/downloadMain.php

Since HG Wells first published his lauded exploration of racial identity, Invisible Man, people have been entranced by the myth of invisible men--be they heroes such as Invisible Woman of the Fantastic four, or villains such as Hollow Man's Sebastian Caine. But is it truly a myth, or do invisible men walk among us? And if an invisible man were to be created, how would we detect him and track his movements?

Fujitsu's Invisible Cameraphone

07/05/2004 10:47 AM

fujitsu_invisible.jpg imageFujitsu has developed a method for invisibly embedding information into printed images as small as a centimeter square. By printing a series of (hopefully) imperceptible yellow dots into an image, up to 12 digits of numeric information can be hidden, allowing a company to embed a phone number or encoded URL. Then, by taking a picture of the image with a cameraphone or PDA, special software can decode the numbers and call the company's phone number or look up their webpage. It's just in a proof-of-concept stage at the moment, but if they can jam a few more bits of data, like say a full character set instead of numbers, it could be a handy technology.

But if it's invisible, how will anyone know it's there? They'll have to make a little logo to indicate it somehow, and then it's not any better than any of the other visual hyperlinking systems out there.

Phil Torrone has done some unusual technical< /a> stunts in the past, but I think he may have set some kind of geek world record with this one.

The Search Engine Belt Buckle is a PDA which shows 24 hours of all the bizarre and banal things people are looking for on the web. Art project or pointless hack? Thats for you to decide, but all we know is that people are searching for some pretty freaky stuff out there, so why not put in a belt buckle and get on the scene like a sex machine?

Has to be seen to be believed. World's first combination belt buckle & date repellent. Wow.

[Side Note: The thing streams by an unedited list of terms people are searching for, so some of the terms are, of course, nasty.]
