Communion Of Dreams


“I, for one, …”

… well, you know the rest.  Granted, the RoboSimian is still tethered, and moves fairly slowly, but it certainly is another glimpse into how quickly robotics are progressing. See for yourself:

Three things.

OK, actually more like four. Maybe. Kinda. Sorta.

You’ll see.

Interesting item on this morning’s Morning Edition, looking at a new book about how scarcity has a psychological impact which pushes people to make poor choices.  The transcript isn’t up yet, so here’s just one passage from the interview with co-author Sendhil Mullainathan:

When you have scarcity and it creates a scarcity mindset, it leads you to take certain behaviors which in the short term help you manage scarcity, but in the long term only make matters worse.

Specifically, it’s a coping strategy: by setting aside some long-term problem, you actually have more time to deal with urgent short-term problems. This is a very normal human reaction, and actually even makes evolutionary sense — not getting eaten today is more important than where that glacier up the mountain will be next year.

I still remember a poster my Resident Advisor had up on her wall in college, which distilled this problem nicely. It said (with appropriate humorous graphic): “When you’re up to your ass in alligators, it’s easy to forget that you came here to drain the swamp.”

I’ve … struggled … with procrastination all my life. Sometimes more successfully than at other times. It can manifest as lethargy. Or writer’s block. Or simple distraction.

And I learned a long, long time ago that that struggle was made worse when I was confronted with other stressors in my life. A bad bipolar cycle. Financial stress.  Emotional stress. Simple lack of sufficient sleep. Just look back through my blog posts while we were doing care-giving for Martha Sr, and you’ll see exactly what I mean.

So when I see someone come up with an interesting take on procrastination, I pay attention. Here’s a very good one:

In the monkey world, he’s got it all figured out—if you eat when you’re hungry, sleep when you’re tired, and don’t do anything difficult, you’re a pretty successful monkey. The problem for the procrastinator is that he happens to live in the human world, making the Instant Gratification Monkey a highly unqualified navigator. Meanwhile, the Rational Decision-Maker, who was trained to make rational decisions, not to deal with competition over the controls, doesn’t know how to put up an effective fight—he just feels worse and worse about himself the more he fails and the more the suffering procrastinator whose head he’s in berates him.

It’s a mess. And with the monkey in charge, the procrastinator finds himself spending a lot of time in a place called the Dark Playground.*

The Dark Playground is a place every procrastinator knows well. It’s a place where leisure activities happen at times when leisure activities are not supposed to be happening. The fun you have in the Dark Playground isn’t actually fun because it’s completely unearned and the air is filled with guilt, anxiety, self-hatred, and dread. Sometimes the Rational Decision-Maker puts his foot down and refuses to let you waste time doing normal leisure things, and since the Instant Gratification Monkey sure as hell isn’t gonna let you work, you find yourself in a bizarre purgatory of weird activities where everyone loses.**

There was a great story yesterday afternoon on All Things Considered, about a little boy who was terrified by a statue of Frankenstein(‘s Monster). It was funny, charming, and insightful.

What insight? This one:

“Well, your nephew is a brilliant story editor,'” says psychologist Tim Wilson of the University of Virginia.

Wilson has been studying how small changes in a person’s own stories and memories can help with emotional health. He calls the process “story editing.” And he says that small tweaks in the interpretation of life events can reap huge benefits.

This process is essentially what happens during months, or years, of therapy. But Wilson has discovered ways you can change your story in only about 45 minutes.

* * *

There’s a second part to that item about procrastination I posted above (hence my ambivalence about whether this blog entry was about three things or four):

There’s only one way to truly beat procrastination:

You need to prove to yourself that you can do it. You need to show yourself you can do it, not tell yourself. Things will change when you show yourself that they can. Until then, you won’t believe it, and nothing will change. Think of yourself like a basketball player on a cold streak. For basketball players, it’s all about confidence, and an ice cold shooter can tell himself 1000 times, “I’m a great shooter, I’m going to hit this next one,” but it’s not until he physically hits a shot that his confidence goes up and his touch comes back. So how do you start hitting shots?

* * *

3) Aim for slow, steady progress—Storylines are rewritten one page at a time.In the same way a great achievement happens unglorious brick by unglorious brick, a deeply-engrained habit like procrastination doesn’t change all at once, it changes one modest improvement at a time. Remember, this is all about showing yourself you can do it, so the key isn’t to be perfect, but to simply improve. The author who writes one page a day has written a book after a year. The procrastinator who gets slightly better every week is a totally changed person a year later.So don’t think about going from A to Z—just start with A to B. Change the Storyline from “I procrastinate on every hard task I do” to “Once a week, I do a hard task without procrastinating.” If you can do that, you’ve started a trend. I’m still a wretched procrastinator, but I’m definitely better than I was last year, so I feel hopeful about the future.

Wait — I said three things? Or maybe four?

I suppose it’s really only one, after all.

Time for me to get back to work.

See it all. All at once.

This is a really cool application of imaging technology: a massed ball of high-quality digital cameras which can capture a gigapixel panorama in one instant.  And the neat thing is that one of the main people behind this understands that while he can imagine some uses for such a camera system, there will come applications which he cannot now envision. From the NPR story:

His team has photographed Duke University football games, for example, that let you zoom in and see the ball in the air, plus the faces of all the players in the field, and the faces of all the fans in the stands.

“I can’t imagine … how people are going to use these things,” Brady says, “and, of course, since I’m an instrument builder, that’s the real interest. Because I’m sure photographers will use it in ways that I haven’t even thought of.”

Nice to see that awareness of shifting reality.

And a quick reminder of another kind of awareness: Communion of Dreams and Her Final Year are both available for free download today and tomorrow.

Linky-link.

Some quick links, none of which really warrant a full blog post.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Wanna be a black-hole hunter? Sure you do! The Galaxy Zoo folks have just launched a new project you should check out:

Search for Black Holes

Black holes are found at the center of most, if not all, galaxies. The bigger the galaxy, the bigger the black hole and the more sensational the effect it can have on the host galaxy. These supermassive black holes drag in nearby material, growing to billions of times the mass of our sun and occasionally producing spectacular jets of material traveling nearly as fast as the speed of light. These jets often can’t be detected in visible light, but are seen using radio telescopes. Astronomers need your help to find these jets and match them to the galaxy that hosts them.

 

We live in the glorious future, where beer concentrate is a real, practical thing!

For fans of craft beer, enjoying a decent brew while hiking or camping away from the car usually involves lugging around heavy cans of beer, which can turn a lovely trek into a grueling slog through the woods.

But now the folks at Pat’s Backcountry Beverages have created a solution – their new Brew Concentrates come in featherweight 50ml packets and can be reconstituted with carbonated water (courtesy of their trail-ready 16-ounce carbonator bottle).

 

Well, actually, the past wasn’t so bad in some ways, either …

When you think of illicit substances that are shipped in brick form, wine probably doesn’t come to mind first. And no, boxed wine doesn’t count. During Prohibition, however, drinkers got around laws that banned alcohol by dissolving bricks of grape concentrate in water and fermenting them into wine.

Of course, conscientious makers of grape bricks didn’t want to contribute to bad behavior, and responsibly warned buyers that, “After dissolving the brick in a gallon of water, do not place the liquid in a jug away in the cupboard for twenty days, because then it would turn into wine.” The makers of the Vino Sano Grape Brick even dutifully indicated what flavors one’s careless handling of grape bricks would result in: burgundy, sherry, port, claret, riesling, etc.

Watch this.

Yeah, what Phil said:

Stop whatever you’re doing (unless you’re performing brain surgery) and watch this astonishing and enthralling time-lapse video, showing the Earth from space using photographs taken by astronauts aboard the International Space Station

Ahh …

Oh, there’s a new review up for Communion of Dreams. Here ’tis:

I rarely read sci-fi anymore, but this reminds me of the best I read when I was younger. There’s a lot of background on the worlds the author is creating, followed by a resolution to multiple problems in the worlds. I truly enjoyed it.

If you’ve read the book and haven’t yet gotten around to posting a review, please consider it. It’s a little thing that does more than just massage my ego — it helps others have some idea what to expect from the book. And every so often I do things like give away nice hand-bound copies of the book . Thanks.

Hey, it’s just $900 million …

Well, that’s terribly surprising: the GAO is out with a new report from their investigation of the TSA’s Behavior Profiling program, and it turns out that it doesn’t work.  From NPR:

WASHINGTON (AP) — A federal probe of a Transportation Security Administration program to screen suspicious behavior of passengers at airports suggests the effort, which has cost almost $1 billion since 2007, has not been proven effective, according to a report released Wednesday.

The Government Accountability Office said its investigation found that the results of the TSA program — called Screening of Passengers by Observation Techniques — were “no better than chance.” Under the program, agents identify suspicious looking people and talk to them to determine whether they pose a threat. The investigators looked at the screening program at four airports, chosen on the basis of size and other factors.

“TSA has yet to empirically demonstrate the effectiveness of the program despite spending about $900 million on it since 2007,” said Steve Lord, who directed the investigation for the GAO. He said the GAO, which is the research and investigative arm of Congress, “conducts active oversight of the TSA for the Congress given their multibillion-dollar budget.” He said “the behavior detection program is viewed as a key layer of aviation security.”

Yeah, a “key layer” that doesn’t work. From ars technica:

It sounds pretty science-y, but it turns out that, in practice, BDOs across the country are referring passengers for secondary screenings at very different rates. For a program based on “objective” biometric measurements of deception, this is not the result one would hope to see. (Even the TSA admitted to GAO auditors that some of the observations were “subjective”; it is trying to rein these in.) And Ekman, who helped set up the program, told GAO three years ago that no one knew “how many BDOs are required to observe a given number of passengers moving at a given rate per day in an airport environment, or the length of time that such observation can be conducted before observation fatigue affects the effectiveness of the personnel.”

For the report, GAO auditors looked at the outside scientific literature, speaking to behavioral researchers and examining meta-analyses of 400 separate academic studies on unmasking liars. That literature suggests that “the ability of human observers to accurately identify deceptive behavior based on behavioral cues or indicators is the same as or slightly better than chance (54 percent).” That result holds whether or not the observer is a member of law enforcement.

It turns out that all of those signs you instinctively “know” to indicate deception usually don’t. Lack of eye contact for instance simply does not correlate with deception when examined in empirical studies. Nor do increases in body movements such as tapping fingers or toes; the literature shows that people’s movements actually decrease when lying. A 2008 study for the Department of Defense found that “no compelling evidence exists to support remote observation of physiological signals that may indicate fear or nervousness in an operational scenario by human observers.”

Like I said, surprising.

Or, you know, not at all.

But at least they spent almost a billion dollars of our money. That’s something.

Broadcast power.

Very interesting technology breakthrough: the use of metamaterials to harvest microwave energy and convert it to DC (direct current), with an efficiency on par with the best solar panels.  From EurekAlert:

With additional modifications, the researchers said the power-harvesting metamaterial could potentially be built into a cell phone, allowing the phone to recharge wirelessly while not in use. This feature could, in principle, allow people living in locations without ready access to a conventional power outlet to harvest energy from a nearby cell phone tower instead.

“Our work demonstrates a simple and inexpensive approach to electromagnetic power harvesting,” said Cummer. “The beauty of the design is that the basic building blocks are self-contained and additive. One can simply assemble more blocks to increase the scavenged power.”

For example, a series of power-harvesting blocks could be assembled to capture the signal from a known set of satellites passing overhead, the researchers explained. The small amount of energy generated from these signals might power a sensor network in a remote location such as a mountaintop or desert, allowing data collection for a long-term study that takes infrequent measurements.

This is a fundamental breakthrough, and one which will have a lot of applications/implications far beyond just those mentioned above. Consider what you could do with even our current electronics technology if you didn’t need to have access to charge batteries/capacitors. Already many devices are charged through induction, though that has a relatively short-range effect, and the magnetic fields used create their own problems (and are relatively inefficient).

Combine this with RFID technology as well as nano-sized processors/memory, and you quickly get to the point where ubiquitous computing becomes not just possible but economically viable. Fascinating.

To sleep, perchance to clear amyloid plaques.*

Interesting. They may have found the reason that animals sleep: in order to flush the brain of toxins which build up during waking hours.

And more importantly, this may also be part of the explanation for Alzheimer’s and other age-related dementia. From the NPR article linked above:

The brain-cleaning process has been observed in rats and baboons, but not yet in humans, Nedergaard says. Even so, it could offer a new way of understanding human brain diseases including Alzheimer’s. That’s because one of the waste products removed from the brain during sleep is beta amyloid, the substance that forms sticky plaques associated with the disease.

That’s probably not a coincidence, Nedergaard says. “Isn’t it interesting that Alzheimer’s and all other diseases associated with dementia, they are linked to sleep disorders,” she says.

Researchers who study Alzheimer’s say Nedergaard’s research could help explain a number of recent findings related to sleep. One of these involves how sleep affects levels of beta amyloid, says , a professor of neurology Washington University in St. Louis who wasn’t involved in the study.

Perhaps it is time for a nap …

New perspective.

Via Phil Plait, had to share this:

Saturn

Saturn, obviously. But from a new perspective, as Plait explains:

But dominating this jaw-dropping scene are Saturn’s magnificent rings, seen here far more circular than usual. Cassini’s mission has been to observe Saturn and its moons, which means it tends to stay near the planet’s equator. But now scientists are playing with the orbit more, to do more interesting science. The spacecraft is swinging well out of the equatorial plane, so here we see the rings at a much steeper angle, and they are less affected by perspective.

And here’s the link to the full-size image, which is definitely worth a look.
