  1. Consequences of Many Worlds on A Mathematical Answer To the Parallel Universe Question · · Score: 1

    According to Deutsch's book The Fabric of Reality (iirc) one of the consequences of Many Worlds is that time travel is logically possible. You can travel back to a different parallel universe and it doesn't matter if you kill your grandfather there because you're not in the same universe you were born in. It's a far-fetched example but it shows that you can't rule out the possibility of a definitive test of Many Worlds.

  2. Re:No, I think you were right the first time. on The Gradual Public Awareness of the Might of Algorithms · · Score: 1

    I bought some children's dvds from amazon about four years ago. I'm still getting recommendations for dvds for the same age group.

  3. Re:Key question: Do we care about -correctness-?? on Forget Math to Become a Great Computer Scientist? · · Score: 1

    Reminds me of a recent dailywtf "how to write a method to calculate factorial thread". I know I've been in development too long when I start by writing

    void testFactorial(){
        assertTrue(120, factorial(5));
    }

  4. Re:I'm a mathematician, and I call BS on Encouraging Students to Drop Mathematics · · Score: 1

    Exactly. It looks tricky, but once you realise it's a kite-shape it becomes a lot easier - especially pt iii where the perpendiculars in the two triangles are then coplanar. Incidentally, the phrasing of the question is confusing - the point E is introduced but is neither properly defined nor used.

  5. Re:It's than the Summary makes out on Encouraging Students to Drop Mathematics · · Score: 1

    The problem requires calculating certain angles. This certainly requires use of some trigonometry - I think the simplest way uses the cosine rule.

  6. Re:Is all of this even illegal?? on Web Censorship Proposed For Norway · · Score: 1

    There were plenty of retail outlets for "genitals in movement" when I lived in Norway from 1998-2001. Have things changed?

  7. Re:It has to be said! on Web Censorship Proposed For Norway · · Score: 1

    How old is Svein Willassen?

  8. Re:The Guard of Freedom on Web Censorship Proposed For Norway · · Score: 1

    Even the Dagbladet article pointed out that it was a minority suggestion. In fact the guy in the photo is a member of the majority on the committee who oppose the proposal. It sounds like a pretty dysfunctional committee.

  9. SPOILER on Harry Potter and the Deathly Hallows Release Date Announced · · Score: 2, Funny

    I have it on good authority that Dudley Dursley turns out to be the last horcrux. Harry cleverly kills Voldemort by stuffing Dudley down Voldermort's throat.

  10. Re:Ummm... on 5 Strangest Materials · · Score: 1

    One of these days, when the kids have moved away and I'm quietly retired, I'm really going to have to try all those psychadelics I missed out on when I was young. (ie all of them) (one at a time)

  11. Re:Damn... on Seventh Harry Potter Book Named · · Score: 1

    Puts me in mind of my dear old Cambridge College library where the "No Refreshments" sign had been vandalised to read "No Freshmen". I had always believed that fresher is an abbreviation of "freshman". The OED seems to agree with me - finding uses of the term "freshman" in a British context from the 16thC up to modern times.

  12. Re:You are all MISSING THE POINT!! on 256GB Geometrically Encoded Paper Storage Device · · Score: 1

    I've always believed that the more I know the less I understand. But I've never before given much thought to the converse.

  13. Re:The harrass pilots as well on Traveler Detained for Anti-TSA Message · · Score: 1

    Please post a link to this story. I so want it to be true.

  14. Film Studies, Clingfilm Studies ... on Star Trek PhD Thesis Wins Academic Prize · · Score: 1

    I like this guy's stuff - http://www.bfi.org.uk/filmtvinfo/researchers/mirr/ researcher/300. His paper on Lord of the Rings-based sexploitation movies at last-year's Tolkien-2005 conference was, er, unique. As was the video-show at the party afterwards.

  15. Re:typo on Under the Hood of Quantum Computing · · Score: 1

    It's a typo for "noobium".

  16. DigiCamera Support on Your Favorite Support Anecdote · · Score: 1

    My mother came back from her cruise-of-a-lifetime with her new digital camera. "Here" she says, "I'll get the thingie from the camera and you can put the photos on your computer". Two minutes later she comes in and hands me .... a battery. "This is not a good sign", thinks I. Later digging around in her actual memory card produces a handful of pictures from the second half of the voyage. What happened to the rest is a mystery, but they were probably wiped by a "helpful" crew-member who provided some "tech-support" of his own at one point during the cruise.

  17. Re:it's not FUD.. on Spain Outlaws P2P File-Sharing · · Score: 3, Insightful

    That's possibly a good thing. Pissing off a few file-sharers won't make any difference, but if they piss off the big ISP's then they may have a fight on their hands.

  18. Re:My #1 annoyance: on Linux Annoyances For Geeks · · Score: 1

    You can be rude ...
    or you could point out why this is a bad idea. It's not like he suggested putting "." at the front of the path. Putting . at the end of the path is potentially dangerous only if there are trojans around based on common typos.
    Has anyone ever seen such malware in the wild?

  19. Re:This article is not challenging peer-reviewed on Scientists Respond to Gore on Global Warming · · Score: 1
    Direct measurements of variation in solar brightness (irradiation) don't really go back before the space age. There are various kinds of proxy measurements that can push it back further. Sunspots can go back to Galileo, or earlier with care. Solar magnetic fields also influence the rate of cosmic-ray bombardment which can be measured over geological timescales.


    The direct effect of changes in solar brightness are probably small. (These guys http://pda.physorg.com/lofi-news-solar-since-sun_6 15.html are a respectable source.) A more controversial idea is that the modulation of the cosmic ray flux by the heliospheric magnetic field affects the rate of cloud formation on Earth ( http://www.dsri.dk/sun-climate/NewPublications.htm ). The idea isn't silly, but it's definitely "fringe", plus nobody really knows what effect it would have on climate if it was true.

    Btw, I'm very impressed with the standard of some of the discussion here. It's good to see people rationally debating the merits of prevention v. adaptation, for example.

    On the other hand, I believe the iLoo spawned a _cottaging_ industry.

  23. National ID Cards on Are National ID Cards a Good Idea? · · Score: 1

    It sounds like a good idea to me. I'm always getting confused between Sweden and Switzerland, New Guinea and Guyana, that kind of thing. If every nation had to carry its own identity card at all times it would be much easier to tell them apart.

  24. Re:cracking this would be useful on Totally Random One Time Pads · · Score: 1

    I don't think it becomes useless if the messages are out of order. There are only 50000 possible starting positions on the pad, so just decrypt the message against each position in turn and check which of those looks like a plausible plaintext (e.g. by frequency analysis).

    I don't get the quasar thing, though. Do quasar signals have no temporal correlation? Perhaps I should just read the damn paper ...
