Proof Mooted For Heisenberg's Uncertainty Principle 158

Posted by Soulskill from the he's-the-one-who-knocks dept.
ananyo writes "Encapsulating the strangeness of quantum mechanics is a single mathematical expression. According to every undergraduate physics textbook, the uncertainty principle states that it is impossible to simultaneously know the exact position and momentum of a subatomic particle — the more precisely one knows the particle's position at a given moment, the less precisely one can know the value of its momentum. But the original version of the principle, put forward by physicist Werner Heisenberg in 1927, couches quantum indeterminism in a different way — as a fundamental limit to how well a detector can measure quantum properties. Heisenberg offered no direct proof for this version of his principle. Now researchers say they have such a proof. (Pre-print available at the arXiv.) If they're right, it would put the measurement aspect of the uncertainty principle on solid ground — something that researchers had started to question — but it would also suggest that quantum-encrypted messages can be transmitted securely."

Ask Slashdot: How Would You Feel About Recording Your Entire Life? 379

Posted by Unknown Lamer from the just-ask-for-your-file dept.
skade88 writes "As I get older, I find the little details of my life slip away from my memory after years and decades pass. I find myself wishing I had a way to record at least sound and video of my entire life. It would be nice to be able to go back and see what I was like when I was younger without the fog of memory clouding my view of the past. It would be cool to share with my boy friend and future kids how I was when I was younger by just showing them video from my life. Do y'all know of any good way to do this? I would settle for recording what I see from a first person point of view. There is also concerns that range beyond the technical. If I were to record my entire life, that would mean also recording other people, when they are interacting with me on a daily basis. What sort of privacy laws pertain to this? Even without laws, would others act differently around me because they were being recorded with my life record? How would it make you feel if your friend or family member did this?"

So, if your browser is configured to keep cookies, does that imply consent to place cookies?

If you configure your browser to disallow cookies from certain sites, you're denying consent, and it doesn't even require the sites to be changed at all.

So, why does this law exist again? It looks -1, Redundant to me.

Submission + - City of Boston pays $170,000 to settle landmark case involving man arrested for (aclum.org) 1

Ian Lamont writes: "The City of Boston has reached a $170,000 settlement with Simon Glik who was arrested by Boston Police in 2007 after using his mobile phone to record police arresting another man on Boston Common. Police claimed that Glik had violated state wiretapping laws, but later dropped the charges and admitted the officers were wrong to arrest him. Glik had brought a lawsuit against the city (aided by the ACLU) because he claimed his civil rights were violated. According to today's ACLU statement:

As part of the settlement, Glik agreed to withdraw his appeal to the Community Ombudsman Oversight Panel. He had complained about the Internal Affairs Division's investigation of his complaint and the way they treated him. IAD officers made fun of Glik for filing the complaint, telling him his only remedy was filing a civil lawsuit. After the City spent years in court defending the officers' arrest of Glik as constitutional and reasonable, IAD reversed course after the First Circuit ruling and disciplined two of the officers for using "unreasonable judgment" in arresting Glik.

Slashdot doesn't seem to mind about Slashdot.jp: Slashbox preview for Slashdot.jp, but I don't know about solidot.org. If you scroll down, they link back to Slashdot.org, but also to a site about an "anticancer herb", which sounds shifty. Also, one of the article submitters, whose names links to Solidot.org, and so is probably a site editor, is called Blackhat :-P
