Mathematical Proof That the Universe Could Come From Nothing

It doesn't come easy Re:Nothing? (429 comments)

And to add ...

At the heart of their thinking is Heisenberg's uncertainty principle. This allows a small empty space to come into existence probabilistically due to fluctuations in what physicists call the metastable false vacuum. When this happens, there are two possibilities. If this bubble of space does not expand rapidly, it disappears again almost instantly.

So, along with quantum fluctuations of "nothing", we also have to include time with this explanation. But, according to Einstein time is an integral part of the space-time continuum...you know, that stuff that was created by the big bang...

Note to theorists, the cart goes in the back...

Apple Pay Competitor CurrentC Breached

Not to defend CurrentC (I'm not), but I read that in order to be a part of the MCX consortium a retailer had to sign a three year contract not to use any other mobile pay system. I wouldn't be surprised if this played some part in turning off Apple Pay functionality.

Not to say that would also explain why Google Wallet was accepted up until Apple Pay went live...because it doesn't...

Yet another possibility is that a comet may have hit the Earth, dumping the extra carbon-14 in the atmosphere. But astronomers have ruled that out on the basis that a comet carrying enough carbon-14 must have been over 100 km in diameter and would surely have left other evidence such as an impact crater.

Not to mention completely obliterating all higher forms of life on the planet, you know, like astronomers...

Senator Dianne Feinstein: NSA Metadata Program Here To Stay

It doesn't come easy Assume the worst... (510 comments)

...and take the control out of their hands.

It's obvious that no one in power can be trusted to NOT collect as much as they can collect. It doesn't matter whether that is a government or a business. There is only one REAL solution. Encrypt everything. And since one cannot trust proprietary solutions to NOT include a back door into the encryption scheme, the only solution is to use open source software AND for such software to be routinely audited by knowledgeable people. And for all of us to be vigilant concerning other ways to circumvent the encryption.

It seems to me that this is a declaration of an arms race between those in power and the average user. But of course, hasn't it always been that way?

Chimpanzee "Personhood" Lawsuits Fail In New York Courts

It doesn't come easy Human soceity not ready for this (370 comments)

Human society is not ready to grant intelligent animals sentient or human status. It sounds like an enlightened idea, but our laws and societal norms cannot accommodate granting these rights without significant and fundamental change.

Take any law that governs the interaction between two humans and apply that to a human verses say a dolphin and you immediately run into serious and unworkable situations. Imagine having to grant a dolphin the right to confront their accuser in a court of law. Really? What about applying laws concerning manslaughter or murder or accidental death? What about representation in government?

Yes, I know the New York case was not about all of these things, but once the door is open you can never close it. Just look at the legal ruling that corporations are legal persons to understand what I mean.

RF Safe-Stop Shuts Down Car Engines With Radio Pulse

It doesn't come easy What an incredibly dangerous device (549 comments)

Basically, this device is causing the car's computer(s) to crash. So, during low speed tests, in a wide open area, the car slowly glides to a stop??? I wonder what might happen if this were applied on a narrow highway, with lots of other vehicles on the road, at highway speeds? And what will happens when this device is used by the disgruntled (postal) worker, or some teens (not picking on teens, I used to be one myself) out for a mischievous time?

What if occasionally the computer's crash in a less expected way -- say for a moment the computer thinks you're trying to "park" (using your computer controlled parking assistant) while traveling at 60 miles per hour?

There are so many things wrong with this that it boggles the mind.

Should the US Copy Switzerland and Consider a 'Maximum Wage' Ratio?

Do you mean the paycheck received on a weekly basis? Do we count stock options or awards? Dividends from preferred stock not available to the average worker? Annual bonuses? Perks (such as the use of a company paid private plane)? Corporate "gifts" of all sorts?

Steve Jobs famously worked at Apple for a one dollar annual salary. However, does anyone here really think that he only made a dollar per year?

The idea has merit, but it is a foregone conclusion that people in power will figure out how to work around the "ratio".

4K Ultra HD Likely To Repeat the Failure of 3D Television

It doesn't come easy Absolutely agree (559 comments)

There is way too must current content that is still not transmitted in 1080p. Buying a new (expensive) TV just to display most shows in standard resolution makes no sense at all. Yes, I know live broadcasts are usually in high def, but one can only watch so must sports on TV. To be fair, I think it is actually a legacy problem. There is so much good legacy content recorded in standard definition that it is tough for new content to compete, at least from a percentage perspective. Best excuse for a good movie or TV series remake that I have heard...

Black Holes Grow By Eating Quantum Foam

It doesn't come easy Re:Con CERN (164 comments)

Actually, it kind of fits if you bring all of the intelligent guesswork together. I read somewhere that the tiny tiny tiny black holes (possibly) created by the LHC would evaporate (due to Hawking Radiation) at an exponentially accelerating rate -- the more mass they lost the faster they would loose more, ending in a quantum sized obliterating explosion. If true, and if this new idea is correct as well, that would imply that there is a perfect point where the mass evaporation from Hawking Radiation would *just* equal the mass accumulation from consuming quantum foam. If the black hole mass starts out greater than this point then the black hole grows, less and it shrinks. Someone ought to be able to calculate (roughly?) the magical amount of mass needed to produce a pseudo-stable black hole...

Big Bang or Big Bounce?

It doesn't come easy It doesn't come easy writes  |  about 6 years ago

It doesn't come easy (695416) writes "Could we be getting closer to testable predictions concerning the state of our Universe at its birth? According to New Scientist, possibly. A relatively new application of the theory of Loop Quantum Gravity, called Loop Quantum Cosmology (or LQC), has been successful in modeling the well known (or at least widely accepted) condition of the Universe well after the point at which Inflation would have ended while at the same time does not require the Big Bang's singularity. The scientists which developed the computer model also expect to come up with "robust predictions" (unlike everyone's favorite string theory) in the next two years."

From the article: Researchers at Temple University in Pennsylvania have developed a small electrorheological device that, when inserted into the fuel line near the fuel injector, can improve fuel economy.

Sony stealth disables DRM restrictions?

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago In what has to be one of the most ironic twists so far in the Sony DRM debacle, a blogger named Nicholas Colyer discovered that by adding the $sys$ to the front of his CD burning software he can now copy as many CD's as he wants. No mention of any real details about the programs involved (apologies to all you hackers out there). One has to wonder, though, just how many other software restrictions can be bypassed by this useful feature? If the stealth function of the original rootkit turns out to be good for lots of other fun things, this could be a real situation for Sony. Nothing forces you to run the stealth removing patch, and I would bet that Sony didn't include an automatic update feature (in which case they would not be able to automatically disable the stealth feature from afar). Might they have to resort to cooperating with Microsoft to add a patch to the regular Windows update process?


Lithium-Ion battery with unprecedented performance

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago A press release from A123Systems announces a new lithium-ion battery technology that delivers unprecedented performance (according to them). The technology is suppose to deliver 10 times the cycle life and 5 times the power over conventional lithium technology, and only require 5 minutes to recharge to 90% capacity. And this is not a theoretical announcement -- the first batteries are now in production and being delivered to the Black & Decker Corporation, who will be utilizing them in a new line of DEWALT branded power tools. The company is also working with the U.S. Department of Energy as part of a major undertaking to develop battery materials for future use in hybrid electric vehicles. Assuming 5 times power means 5 times range (may not be the case but hey let's dream a little, ok?), an all electric car that only had a 70 mile range would be able to go more than 300 miles between charges and only take 5 minutes to recharge at the station. Might this make fuel cell cars (and hybrids) obsolete before they even get started? On a side note, there have been other promises of breakthroughs for lithium based batteries before...wonder if there is a patent lawsuit in the making? This press release is also mentioned over at Green Car Congress.


NASA has a plan for asteroid deflection

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago The Register is reporting that NASA has started developing a contingency plan to deflect a quarter-mile wide asteroid if indeed it looks to threaten the Earth in 2029. The asteroid formerly known as 2004MN4 has now been named 99942 Apophis. The space agency says that if the asteroid still appears to be threatening Earth by 2013, it will start work on a mission to visit Apophis with a probe in 2019. This would be followed by an attempt to deflect the asteroid some time between 2024 and 2028. NASA's plans to deflect the asteroid were first publicly revealed by the B612 Foundation.


Mazda's New Smart Idling Stop System

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago Now this is really thinking outside the box...Mazda is displaying a new form of an idle-stop system for direct-injection spark-ignition engines that uses combustion and the reverse operation of the engine as a restart trigger rather than an electric motor. To summarize: The Smart Idling Stop System shuts off the engine when you come to a stop. When you want to go again, the system injects fuel into the cylinder in the compression phase but not yet at the top of the compression cycle (in a four cylinder 4 stroke engine, one cylinder is always in the compression phase). Then the fuel is ignited to force the compressing piston back down in the opposite direction. This causes compression in a different cylinder which then has fuel injected and ignited, which in turn forces the engine to turn back in the normal direction and provides enough power to kick start the engine back to life. In order for everything to work, the Smart Idling Stop System forces the engine to stop in a position that is optimal for the next restart attempt. Mazda claims that the Smart Idling Stop System is more energy-efficient than an electric motor restart, and also restarts the engine more quickly and quietly than a conventional idle-stop system.


The Ultimate Flex-Fuel and Flex-Combustion Engine

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago Two California inventors have designed and patented the ultimate flex-fuel and flex-combustion engine: an engine that can adapt in real-time to a variety of petroleum-, bio- or gaseous-fuels using the appropriate combustion mode, including spark-ignition, compression-ignition or HCCI variants. The design eliminates the last mechanical constraint for a totally electronically controlled engine, namely the cam shaft, and allows each cylinder to be independently fine tuned in real time for a wide range of power options. Possibilities range from boosting compression for more power to using air compression only (no fuel) for braking to even storing the compressed air for extra power later on. Now all they have to do is get someone with lots of money interested in developing it further.


ALERT: YOU may be guilty of copyright infringement

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago This has to be the funniest thing (at least to my dry sense of humor) I've run across in a while -- and I'm not even sure these guys aren't serious. A company(?) called Magnus-Opus warns "You may be inadvertently performing one of the Magnus-Opus melody series each time you use your telecommunications device (telephone, mobile telephone, modem and other internet devices)". Fortunately, they provide a web site that lets you test any number against their database of copyrighted melodies. If you are found to infringe, they helpfully point you to their licensing page. Licenses range from "single performance" for 5 cents (per performance) to lifetime "full performance rights" costing up to $10,000. And if you don't wish to buy a license, they have a FAQ that details how you can get rid of the offending telecommunications device. Originally brought to you by an anonymous reader on Spencer Katt.


It pays to conserve energy in 2006

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago As reported by MSNBC, you could collect as much as $7,400 or more in tax credits if you spend a lot of money on energy saving stuff starting in 2006 and going through 2010, courtesy of the energy bill signed into law by Pres. Bush in August of this year. Here's how the credits work: Buy or lease a hybrid gas-electric vehicle and qualify for a tax credit of up to $3,400. Install solar power in your home and get up to a $4,000 tax credit. Make your home more energy efficient and get credits ranging from $50 to $500. The bill has some (IMHO) odd provisions, however. For example, [hybrid] credits are capped at 60,000 vehicles per carmaker and then start tapering off rather drastically, [and that means] they could phase out fairly quickly for companies with the best-selling hybrids. To put that into perspective, consider that Toyota is projected to sell 60,000 hybrids by the middle of 2006. Bottom line, if you're planning to buy a Prius next year, better do it before the end of May if you want to get the full tax credit...

Sales of Full-Size SUVs Crater in September

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago GreenCarCongress reports that combined sales of full-size SUVs dropped 43.5% in September from the year before. GM and Ford, the most dependent on SUV sales, were the hardest hit, with drops of 42.5% and 54.5% respectively. Interestingly, two SUVs sold more in September: The recently discontinued Ford Excursion and the Hummer H1. Of course, anyone who buys an H1 never worried about gas milage before -- why start now?


What Is Web 2.0

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago Over at O'Reilly.net, Tim O'Reilly has written a rather longish article on the concept of "Web 2.0", first defined (according to Tim) during a conference brainstorming session between O'Reilly and MediaLive International sometime back in 2003. Web 2.0 centers around the concept of the Web as Platform (recent Slashdot articles about the Web as Platform). Google, of course, is the poster child for Web as Platform, being described as "an enabler or middleman between the user and his or her online experience." Other characteristics of Web 2.0 include Harnessing Collective Intelligence (example Wikipedia), Data is the Next Intel Inside (example Amazon.com's highly successful user rating system), End of the Software Release Cycle (example, Google's perpetual updates to its web indices), Lightweight Programming Models (example RSS), Software Above the Level of a Single Device (i.e. the service is accessible from a variety of devices, example accessing real time traffic updates), and Rich User Experiences (example Google Maps). A very interesting read concerning the direction the Internet is moving.


Robotic Greenhouses

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago Here's a predicament that happens all too often in our short term profit driven economy...tens of thousands of empty storage containers, manufactured in Asia and shipped to the US full of product, now lie stacked in towers alongside I-95 in New Jersey. The problem? They are too cheap to be shipped back to Asia but too expensive here in the US to recycle. Of course, one man's garbage is another man's business opportunity. According to Wired News, Lior Hessel of OrganiTech believes those containers would make ideal miniature robotic farms. The idea is to use OrganiTech's robotic greenhouse system to convert the containers into miniature farms that grow food close to where it is consumed, thereby saving most of the transportation cost. OrganiTech's system is entirely free of pesticides (the greenhouses keep positive air pressure inside the structure, so few if any insects can fly in) and are grown hydroponically (without soil) so nutrients, fertilizers and water requirements are one-third to one-fifth the needs of soil-grown lettuce (lettuce is used as an example for cost comparison in the article). In addition to food produced for consumption, OrganiTech is also in talks with several pharmaceutical companies to create custom "plant factories" for genetically engineered crops that produce medically useful compounds. And best of all, with the farms being entirely automated, the cost of labor would consist of a single computer technician's salary. Is there a robotic greenhouse in your future?


Sun's role in global warming may be underestimated

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago An announcement on EurekAlert says that at least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities. This has been claimed before. This is not to say that greenhouse gasses are off the hook, but it means that climate change models need to be adjusted accordingly. I would say another piece of evidence for increased solar output may have been found by the Mars Orbiter, where surveys show for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress (the Mars Orbiter report was also featured in this Slashdot submission).


Smaller Cars Enjoy New Chic

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago The Washington Post has an article on the increased interest in fuel efficient cars after the recent hurricanes in the US and their affect on gas prices. It seems Toyota and Honda are struggling to keep up with demand, while GM and Ford have seen a serious drop in sales of large SUV's. Is this the start of a lasting change in the US market or is it just a knee-jerk reaction? What's the next car you plan to purchase?


Universe evolution favors 3 and 7 dimensions

It doesn't come easy It doesn't come easy writes  |  more than 9 years ago In case anyone was wondering why we live in a universe with 3 infinitely long directional dimensions, Andreas Karch (University of Washington assistant professor of physics) and his collaborator, Lisa Randall (of Harvard) says it's because the natural evolution of universes (or more specifically the branes described in M-Theory) favor the eventual formation of a universe where you end up with either 3 or 7 infinite physical directions (the remaining dimensions shrink to a minuscule size). Other numbers of physical dimensions are possible, just not favored. An interesting note, the good professor implies that our universe actually contains many regions with different numbers of spatial dimensions at the same time; we just happen to live in a region that ended up with 3 spatial dimensions.

The announcement also implies that our universe is infinitely large and has big bangs happening inside it somewhere all the time. On the other hand, it has also been theorized that two branes colliding might have created what we call the universe.

Karch and Randall detail their work in the October edition of Physical Review Letters, published by the American Physical Society.
