It's like expecting Google search to suddenly gain sentience

Meet Watson, it beat the best humans in the open ended problem domain of "game show trivia" using natural language processing. When it won the Jeopardy championship it had 20 tons of air-conditioning and a room full of servers. Today it runs on a "pizza box" server and you can try it out yourself. After Jeopardy it went back to working with various medical institutes where it was trained and fed on a steady diet of medical journals, it's now well past the point where it became knowledgeable enough to pass the test for a US GP's license.

True Watson is blind, but I suspect the problems with visual input is more about the human teacher's failure to provide the right context and experience than it is about the artificial students ability to learn.

Comment Hydrogen blimps (Score 1) 200

I don't see why they would use helium. Hydrogen would be much easier to deal with since it can be readily extracted from the hydrogen sulfide clouds. There wouldn't be any Hindenburg's since there's no oxygen in the atmosphere to react with.

It's also more bouyant, so the gas bag would be smaller for the same weight, and you could launch it from earth with less delta V.

Submission + - Is the Higgs Boson a Piece of the Matter-Antimatter Puzzle? (stanford.edu)

TaleSlinger writes: Why there's more matter than antimatter is one of the biggest questions confounding particle physicists and cosmologists, and it cuts to the heart of our own existence. In the time following the Big Bang, when the budding universe cooled enough for matter to form, most matter-antimatter particle pairs that popped into existence annihilated each other. Yet something tipped the balance in favor of matter, or we – and stars, planets, galaxies, life – would not be here.

The paper is based on a phenomenon called CP – or charge-parity – violation, the same phenomenon investigated by BaBar. CP violation means that nature treats a particle and its oppositely charged mirror-image version differently.

"Searching for CP violation at the LHC is tricky," Dolan said. "We've just started to look into the properties of the Higgs, and the experiments must be very carefully designed if we are to improve our understanding of how the Higgs behaves under different conditions.”

The theorists proposed that experimenters look for a process in which a Higgs decays into two tau particles, which are like supersized cousins of electrons, while the remainder of the energy from the original proton-proton collision sprays outward in two jets. Any mix of CP-even and CP-odd in the Higgs is revealed by the angle between the two jets.

"I wanted to add a CP violation measurement to our analysis, and what Matt, Martin and Michael proposed is the most viable avenue,” Philip Harris, a staff physicist at CERN and co-author of the paper said, adding that he's looking forward to all the data the LHC will generate when it starts up again early next year at its full design strength.

"Even with just a few months of data we can start to make real statements about the Higgs and CP violation," he said.

Isn't this something everyone already knew, radical warmists and evil deniers alike?

Maybe, but statistical thinking doesn't come naturally. People cheat at gambling by loading dice so that they come up snake eyes (say) 1 in 20 throws. They get away with it because even if you know the dice are loaded there is no way to link any particular snake eye event to the hidden weights. The victims simply subscribe it to luck, but the longer you play the more suspicious they will become of your "lucky streak". Same deal with storms, floods, and droughts.

Submission + - Neil deGrasse Tyson causes social media firestorm with tweet on aliens & hum (examiner.com)

MarkWhittington writes: Twitchy, a site that monitors interesting traffic on Twitter, took note on Sunday of a tweet by the celebrity astrophysicist Neil deGrasse Tyson over how aliens might regard humans. He tweeted, “Aliens, seeing Humans kill over land, politics, religion, & skin color, would surely ask, ‘What the f*%k is wrong with you?’” As far as can be determined, Tyson is not personally in contact with aliens and does not have any basis to suggest that they are appalled at human behavior or that they used salty language. However, his views on morally superior aliens looking down on humans seem to track with those of C.S. Lewis, a Christian apologist.

Comment Re:THERE HAS NEVER BEEN CLIMATE STASIS! (Score 1) 401

Seriously?

If we are being 'serious', nobody has claimed there is such a thing, however the climate our civilization has experienced in the last 10k yrs has been in a very stable "dynamic equilibrium". That is set to change because humans are kicking the crap out of the climate system, it will fuck up our agriculture, flood our coastal cities, and cause mass migration. How much worse it gets is depends on how we behave, if continue on our current course then the laws of physics say the ocean will become acidic in the 2100's - the last time such an event happened naturally, it coincided with the worst ever extinction event known to man.

We have already got a taste of how climatic changes can cause social disruption in Syria. The "arab spring" was preceded by the worst drought in the 10ky history of the fertile crescent (the birthplace of agriculture). The 'unprecedented' drought caused people to abandon their farms and set off food riots in major cities such as Cairo and Aleppo. In Syria agriculture totally collapsed, a full 10% of the population (2M people) simply walked off their "dust bowl" farms just prior to the civil war, coincidence?

Comment Re:Out with the old... or not? (Score 5, Insightful) 295

I drove a cab in Australia for 3yrs, it's not the worst job I've had but it's certainly the worst paid job, think fruit picking money. Most cabbies don't own the cab or the plates (medallion). The cab owners are the ones who are understandably getting upset since if uber is legal the plates they paid hundreds of thousands of dollars for suddenly become worthless.

Uber drivers are desperate for work and silly enough to run their own car into the ground for little more than petrol money, when it's dead they can't afford a new one and walk away in a worse situation than they started. Courier companies do the same thing here in Melbourne, they call you a "sub-contractor" get you to stick a "courier" sign on your own car then you drive it at your own expense until it falls apart. And if you're unlucky enough to fuck up without the right insurance, you will be paying for it the rest of your life.

From my experience with real cabs, sticking with a regulated taxi industry is the best thing any of us can do to stop uber exploiting desperate people in a race to the bottom.

Submission + - Stem Cell Treatment to Regrow Torn Meniscus 'Very, Very Close' (healthline.com)

LesterMoore writes: In a new study, researchers put 3D model meniscus in sheep's knees. (Their joints are a lot like humans'.) The model attracted stem cells to it and supplied growth factors and eventually biodegraded. New working menisci grew and the sheep regained full mobility. Orthopedists say similar treatments for humans are "very, very close," according to one article.
