  1. how many events is considered significant? on Growing Consensus: The Higgs Boson Exists · · Score: 2

    I did not really see that number stated in the various articles. I read that the US Tevatron saw a 'hint" of Higgs with three possible events.
    The other thing I read in Physics Today is there are six classes and over thirty ways the Higgs can decay. Some ways are easier to see with current detectors than others. The July 4 announccment was based on at least two decay modes. The more modes the more confidence.

  2. down to 3 or 4 RTGs on NASA Restarts Plutonium Production · · Score: 1

    I had heard they had less than 30 Kgs left and it took at least 5 kgs to run the older style RTGs. The newer Stirling RTGs increase efficiency some.

    Plus the cost at $4M a kilo was becoming significant.

  3. not overly impressed with movie on 10 Ways To Celebrate International Pi Day · · Score: 1

    I found myself checking the time a lot. Perhaps it was the lack of dialog during the majority of the movie when there was just one human. Castaway had a similar problem.

    I was shocked to hear Rhythm & Hues who got an effects Oscar for this movie had gone bankrupt. They had a real nice 25th anniversary presentation at 2012 SIGGRAPH.

  4. chemist and Jesuit on New Pope Selected · · Score: 1

    That makes him a formidable academic type. I wonder if we have had a STEM Pope before.

    A guy from my MIT class is also a Jesuit and Vatican Astronomer. Spends a lot of research time in an Arizona telescope complex the Vatican co-owns. I've only ran into him once since graduation.

    Academic types are necessiarily the best fro running something as large and injured as the Catholic Church. Probably they chose him for other qualities. The last pope was too much like a college porfessor and considered too quiet.

  5. Peak Oil is now in 2030s on Japan Extracts Natural Gas From Frozen Methane Hydrate · · Score: 1

    According to USGS and most oil companies. Especially with the production of tight hydrocarbons (fracked). Hydrates could delay the peak another decade, two or three. BUT THERE WILL STILL BE A PEAK. Buys time for alternative energy and efficiency.

  6. Methane Hydrate highly pressurized on Japan Extracts Natural Gas From Frozen Methane Hydrate · · Score: 2

    Drillers intentionally avoid it because it blows up wells and catches fire. Thats what happened three years ago for the Mocando Deep Horizon Well. (regular overpressured methane, not hydrate)

    Scientists have a pretty good idea now how to detect it on a conventional seismic section, whether they want to avoid it or drill for it. Its seems to be in continental shelves over much of the world.

  7. methane has shorter lifetime on Japan Extracts Natural Gas From Frozen Methane Hydrate · · Score: 5, Informative

    Methane is less stable than CO2. Its lifetime in normal atmoshperic sunlight is about two decades. CO2 stays for thousands of years.

  8. I read those Wikileaks in the NYTimes on What If Manning Had Leaked To the New York Times? · · Score: 1

    They made a deal with a London newspaper to redact, edit, and publish many of the documents.

  9. she sounded arrogant on 60 Minutes on Sheryl Sandberg and Technology's Female Leaders · · Score: 1

    But CEOs/COOs are not really that humble.

  10. Andromeda "collision" is more scary on Astronomers Discover Third-Closest Star System To Earth · · Score: 3, Insightful

    Andromeda is trillions of times more massive and will "collide" with the Milky Way in two billion years. But they will interpetrate each other like ghosts passing in the night. Odds are unlikely there wont be a single stellar collision among the trillion stars during the Big Merge. The night sky will become rather interesting with multiple stellar bands lighting the sky.

  11. new dark matter results any day now on Astronomers Discover Third-Closest Star System To Earth · · Score: 3, Interesting

    That very expensive special detector on the Space Station is reputed to announce interesting results any day now. Detecting certain classes of dark matter was one of its capabilities.

    Congress had to fund a special extra shuttle launch to get this into orbit. Furtmore, the physicists decided to swap in a new set of magnets last minute, postponing it over a year.

  12. MIT turned half female in past 20 years on MIT's Charm School For Geeks Turns 20 · · Score: 1

    That has as big of an effect as charm school. The guys have more opportunities to socialize than when I attended at 90% male.

  13. Pongyang would be obliterated in 30 minutes on North Korea Threatens US With Preemptive Nuclear Strike · · Score: 1

    If anything this serious happened. The child-leader is throughing a tantrum again.

  14. keep on building new bank branches on Do Kiosks and IVRs Threaten Human Interaction? · · Score: 1

    Long after ATMS could hand most physical money transactions and online banking about everything else. Maybe I visit a physical branch once a year at most. But I still see plenty of people in them on Saturdays.

  15. $50 tablet or unlocked smartPhone says so on Chinese IT Ministry Looks Askance At Google's Control of Android · · Score: 2

    Most of my kitchen appliances and electronics are Chinese now. Whos what they are doing when i am sleeping? :-)

  16. resolution in numerical analysis on Physicists Discover a Way Around Heisenberg's Uncertainty Principle · · Score: 2

    You can only know the qualities sampled on a discrete digital grid to certain resolution due the limits of the grid. Take a Fourier transform of quanity sampled on that grid. You can only reliable compute frequencies with wavelengths two grid points wide. Else "aliasing" allows you fit an arbitrary number of smaller wavelengths to the same sample points.

    In nature the Planck unit of action discretizes the universe into the smallest quantities you can resolve.

  17. genetic marker testing used now on The Next Revolution In Medicine: Genome Scans For Everyone · · Score: 1

    Its not a full sequencing, but a search for about a dozen genetic markers unique to the equine species. I was trying to find an exact description of the test in google, but the best I could was company called InstantLabs selling a machine . It takes two hours to analyze a sample. Not quite GATTACA yet.

    Unfortunately each test is species specific. So if you want to test for lots of species you have to run lots of tests, assuming they are available.

  18. try to watch a launch if you can on SpaceX Launching Dragon Capsule to ISS Today · · Score: 1

    Both the launch company and congressman may have cle-in tickets.
    I did this a couple years ago. we were at the standard press area about 3 miles away. The rocket flare was much brighter than i had anticipated- almost too bright to watch. However it was quieter than I had thought.

  19. smart glasses verses smart watches on Sergey Brin Says Using a Smartphone Is 'Emasculating' · · Score: 1

    Both are attempts to bring the portable computer closer and more seemlessly to your body. In a decade a full computer may be shrunk to that those form factors (decent prototypes now).

    I would think the glasses, close to your eyes, ears, and mouth would eventually be the better interface.

  20. they tour scifi conventions on 2001: a Space Odyssey's Dave Returns To Sci-fi In New Film · · Score: 1

    I didnt realize that Lockwood had done the 2nd Star Trek pilot shortly before 2001. One of my favorite episodes with the guy who acquires godly psychic powers and eyes turn silver.

  21. projects at MicroSoft, Google, MIT Media on Ask Slashdot: How Would You Feel About Recording Your Entire Life? · · Score: 1

    These started in the 1990s when cameras were bulking and flalsh was measured in megabytes. Even then the issue was "retreival": how do you find anything you recorded. They pretty much id clever things like only record when there was motion as not to keep hours of "dead time".

    I suppose this could be a mode in Google Glasses. GPS and Voice will annotate and control.

  22. similar aguments against tanks & machine guns on Human Rights Watch: Petition Against Robots On the Battle Field · · Score: 1

    NPR had a piece that same kinds of arguments have been made against every new escalation of military technology back to metal swords and the gun itself. That technology increases the soldiers killing capacity and makes him/her more removed from man-to-man combat.

    The real jump would be machine-decided (A.I.) killing. For the most part there is a man in the decision loop. Even with the new Israeli "Iron Dome" missiles where operator has seconds to decide to launch. (More of a financial decision because they cost $75K apiece.)

  23. swiss cheese curriculum on The Two Big Problems With Online College Courses · · Score: 1

    There is not a complete sequence of courses for any discipline yet in the three MOOC companies. Thats OK for someone like me who already has a grad degree, but not for basic students.

  24. 10 million times more data than DNA on US Joins Google, Microsoft In "Brain Race" · · Score: 3, Interesting

    There are 13 billion bits of information in a human DNA sequence. A brain has a trillion cells of several dozen types that may touch 10,000 other cells. You are talking about a 100 quadrillion edge graph there.

  25. curious Koch brothers contradition on Billionaires Secretly Fund Vast Climate Denial Network · · Score: 2

    All of them graduated from MIT with engineering degrees in the 1960s. One brother- David- focuses on science and education charities. He has funded the New York Science Museum Hall of Evolution - probably the best dinosaur exhibit in the world. He also funds the very liberal Aspen Institute in Colorado.

    Perhsps they are moderating some of the over-zealousness of the climate change supporters. Its almost as silly to have them find GW under every rock as it is for anti-climate change peope to deny every observation.
