Scary how we are being manipulated! The lesson of the story is to trust no one... umm including me?!? Damn...
You are being tracked, profiled, and emotionally manipulated. And you're probably complicit (ever take a Facebook quiz?)

This article has been bothering me since I first saw it a couple of days ago. This is kind of the dark side of what I do with my clients. Instead of using data to help people understand others, or find good customer/business matches, this is using the same techniques on a huge scale (220 million profiles in their database) in order to win partisan battles.

I know a lot of the people I connect with are not entirely comfortable with technology. But you really should do two things: 1) read this article to get a sense of scope, and 2) consider learning some basics of data science, analytics, data collection, and so forth as part of your civic engagement.

Yes, you should vote, but you should also know what techniques are used to push your vote one way or another. All humans are subject to influence, and it's becoming clear that just watching the news (or your social media feed) and making your choice to vote for isn't enough.

"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.

"It’s somewhat ironic that, from my personal experience, the situation is actually worse in Loop Quantum Gravity, an approach pioneered, among others, by Lee Smolin. "

It's like Clinton vs. Trump...
String phenomenology of the somewhat different kind
[Cat’s cradle. Image Source .] Ten years ago, I didn’t take the “string wars” seriously. To begin with, referring to such an esoteric conflict as “war” seems disrespectful to millions caught in actual wars. In comparison to their suffering it’s hard to take...

Dear Dr B: Why not string theory?
[I got this question in reply to my last week’s book review of Why String Theory? by Joseph Conlon .] Dear Marco: Because we might be wasting time and money and, ultimately, risk that progress stalls entirely. In contrast to many of my colleagues I do not t...

"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...

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"
