Spooky action at a distance (updated)hansonlab.tudelft.nl

Here’s a video from TU Delft explaining quantum “spooky action,” which they claim to have proven to exist in their experiments.

Video

Update: this video is, ironically, unavailable to inform us at a distance. There is a version hosted elsewhere however. Thanks, NYC Mesh!

Update 2: it seems the video is working again. Weird!

From the NY Times:

The Delft study, published Wednesday in the journal Nature, lends further credence to an idea that Einstein famously rejected. He said quantum theory necessitated “spooky action at a distance,” and he refused to accept the notion that the universe could behave in such a strange and apparently random fashion.

Why we don’t have much good data on gunswww.nytimes.com

From Michael Luo’s 2011 series on guns and public safety, this gets at the heart of the political limitations on doing research into the health risks of guns in America.

C.D.C. financing for research on gun violence has not stopped completely, but it is now mostly limited to work in which firearms are only a component.

The centers also ask researchers it finances to give it a heads-up anytime they are publishing studies that have anything to do with firearms. The agency, in turn, relays this information to the N.R.A. as a courtesy, said Thomas Skinner, a spokesman for the centers.

Invariably, researchers said, whenever their work touches upon firearms, the C.D.C. becomes squeamish. In the end, they said, it is often simply easier to avoid the topic if they want to continue to be in the agency’s good graces.

Emphasis added. I’m curious if these circumstances have changed much in the past 4 years.

Ray Bradbury 1963 filmwww.theatlantic.com

A 25 minute video on Ray Bradbury from The Atlantic.

I love that he lived in Los Angeles but didn’t drive a car. There’s also this moment at 4:25 where you see a sign above his desk “DON’T THINK.” Seems like sound advice for how to conduct yourself behind a keyboard, so I’ve added a similar one to my own desk.

The paralyzed rat is not walkingwww.reuters.com

I’ve seen this video going around, advancing the idea that science has enabled a paralyzed rat to walk. This follows on some other impressive medical feats like the brain-controlled robotic arm.

The thing that struck me in the video, though, is that the rat is moving involuntarily. The rat’s body is walking, but it’s an advanced QWOP-style computer algorithm that’s in control. To me this research seems more similar to those creepy Boston Dynamics robots than other advances in rehabilitative medicine.

The rat, in this case, is just a meat-based robot. Now watch the video with that in mind, watch the spasms of the front legs, and the cooing encouragement from the lab tech. Creepy right?

Luxury goods make you selfishwww.reuters.com

The students who viewed luxury goods were significantly more likely than the second group to endorse production of a new car that might pollute the environment, launch a new software with bugs, or market a video game that might induce violence, according to the study.

“Results … suggest that when primed with luxury, people endorsed self-interested decisions that could potentially harm others,” the researchers said in the study.
