"My misgivings of quantum mechanics are pretty much identical to the ones which Weinberg expresses in his lecture. The axioms of quantum mechanics, whatever interpretation you chose, are unsatisfactory for a reductionist. They should not mention the process of measurement, because the fundamental theory should tell you what a measurement is."

Well said!
 
Steven Weinberg doesn’t like Quantum Mechanics. So what?
A few days ago, Nobel laureate Steven Weinberg gave a one-hour lecture titled “What’s the matter with quantum mechanics?” at a workshop for science writers organized by the Council for the Advancement of Science Writing (CASW). In his lecture, Weinberg expr...

Traffic jams as explained by SCIENCE!!

I was trying to find this article and video some time ago, but with no luck... but here it is: Navier-Stokes equation for Drivers ;)

(OK not really NS but the 1D version a.k.a Burgers equation should be a pretty good approximation of what happens in there...)
 
An actual experiment that shows how car jams start and grow. It is enough with a small disturbance in the form of a car breaking to create a jam further back in the flow. The results were published and can be read here: http://www.firenzeinbici.net/public/njp8_3_033001.pdf.

I always thought 3D printing enthusiasts were people who'd been shielded somehow from 2D printing woes.

LOL "Oh hang on, there's a bee on my arm... " Hilarious XD

Gotta have this as an app for my phone (and in Finnish)
Hanging up on annoying telemarketers is the easiest way to deal with them, but that just sends their autodialers onto the next unfortunate victim. Roger Anderson decided that telemarketers deserved a crueler fate, so he programmed an artificially intelligent bot that keeps them on the line for as long as possible.

"DeepMind’s program AlphaGo beat Fan Hui, the European Go champion, five times out of five in tournament conditions, the firm reveals in research published in Nature on 27 January"

Holy crap!!
 
Huge news from our colleagues at DeepMind. Go was long considered a key problem for AI, because it's a game for which the 'try all combinations and see which does best' is simply not possible, and human Go players rely heavily on abstract pattern recognition to guide their decisions. This is further evidence that human-level pattern recognition is no longer a 'science' problem per-se (but still a mighty engineering problem). It's time for us to focus more on exploring higher levels of cognition.
Deep-learning software defeats human professional for first time.

My bet is that AlphaGo will also beat the world champ in their upcoming game.

"But CO2 emissions have negative consequences that can ripple through the environment, disrupting the Earth’s feedback mechanisms that keep the system regulated"

So we see a negative feedback effect as increased vegetation due to increased CO2 (more CO2 -> increased vegetation -> less CO2), but there are now some complex really really sensitive feedback effects that could completely derail the environment??

Sounds reeeeally plausible because, like, we all know how sensitive life on earth can be, because life on earth has only existed like a few billion of years or so...

A new study suggests that carbon dioxide emissions have caused a huge increase in plant greenery, amounting to about four billion sequoias.

+John Baez Our cultures and societies could be fragile, but civilization in general sense, as a sum of technologies and tools to realize them considerably more robust. It's enough for one pocket of high-tech manufacture with high energy source (nuclear reactor or large fuel deposit) to survive and it will propagate itself across all available space in several decades. It don't even have to be completely closed loop - lost component could be replaced with fast-developed lower technology.

Damn I just knew it:

"Amalric’s study found that mathematicians had reduced activity in the visual areas of the brain involved in facial processing. This could mean that the neural resources required to grasp and work with certain math concepts may undercut—or “use up”—some of the brain’s other capacities"
Processing high-level math concepts uses the same neural networks as the basic math skills a child is born with

I wonder, at turns, about the commonalities between mathematicians and artists, especially musicians.  I've observed that many of both have a few peak years, when they're doing truly superior work.  After that, they might continue in their craft, but they've peaked somehow....

Story

Math PhD Python guy
Introduction
I'm a Finnish mathematician and theoretical physicist with research experience and interests in artificial intelligence and machine learning, time series modeling, nonlinear phenomena and turbulence, differential geometry, gauge theories and gravity. I have PhD in math and Master's in theoretical physics, but I consider myself more theoretical physicist than a mathematician.

I work as an artificial intelligence researcher at The Curious AI Company.

Kannattaa olla varovainen näiden veijarien kanssa. Etenkin herra A.S. kusettaa enemmän kuin korillinen keppanaa... Ensimmäisellä kerralla piti mm. paikata ruostevaurioita, mutta myöhemmin kävi ilmi ettei mitään oltu tehty. Toisella kerralla oltiin hankkimassa ABS anturia Fixusista, ja se maksoi kuulemma 181€. Sanoin, että vien auton pois ja hankin varaosan itse muualta. "Ei sitä voi enää perua, se on jo tilattu!" Itse kuulin puhelun, jossa kaveri sanoi että varaosaa löytyy varastolta! "Ai niiiin joo just joo (seli seli)". Vein auton pois ja soitin itse Fixusille: varaosan hinta olikin 131€! Varskinkin jos hinnasta ei olla sovittu etukäteen tulee mukaan ihmeellisiä lisäkustannuksia...
