Monday, October 27, 2008Nokia has an enormous digital presence at London Heathrow’s new Terminal 5: a display about 30 feet long projecting Nokia lifestyle ads around the clock. The display is mounted on the upper level between the security checkpoints, overlooking the main hall downstairs. How much do you think that costs? And how good is the advertising at prepping people for the Nokia store on the lower level?
My favorite airport advertising, however, is in Switzerland’s Zurich airport, where ads are projected against the tunnel wall just outside the train windows, and follow you as you are shuttled from one terminal to another. Very slick.

“Just peeling tape is the quickest, cheapest way to provide X-rays… It’s X-rays for everyone.”
Peeling tape from a roll of Scotch releases tiny bursts of X-rays that are powerful enough to take images of bones in fingers and hands, researchers have found.
The unusual discovery was made by a University of California at Los Angeles team, intrigued after hearing that Soviet scientists in the 1950s found that sticky tape, when separated at the right speed, released pulses in the X-ray part of the energy spectrum.
Reporting in Thursday’s issue of the British-based science journal Nature, the investigators used a motorised peeling machine to unwind a standard roll (25.4 metres in length by 19 mm) of Photo Safe 3M Scotch tape at a speed of three centimetres (1.18 inches) a second.
By placing the machine in a vacuum, they were able to measure X-rays that were enough to take images.

Yowsers. Isn’t anything safe anymore?
Carnival of the Mobilists #144 is now up at Xen Mendelsohn’s Xellular Identity blog (cheers from Israel!). My “On Delaying Gratification” post of Sept. 28 is included. Have a look to see this week’s best writing on everything mobile!

I’ve heard over the years that DOS [and Windows] sometimes err in calculations over a certain size. Something to do with floating points, I think. Anyway, I never understood the problem, so I appreciate that this report of Google Calculator having trouble includes an explanation:
It’s not a simple case of a cutoff where things fall apart, though. 1,999,999,999,999,999 minus 1,999,999,999,999,995 incorrectly equals 0, but 1,999,999,999,999,999 minus 1,999,999,999,999,993 correctly equals 6. And 400,000,000,000,002 minus 400,000,000,000,001 incorrectly equals 0, but 400,000,000,000,002 minus 400,000,000,000,000 correctly equals 2.
Perhaps most amusing for the schadenfreude crowd, Google botches some math involving a googol, which is 1 followed by 100 zeros. The quantity of a googol plus one, minus a googol, equals 0 rather than the correct result, 1.
Dear Fifth Graders:
How do you do! I am the little book that you have made. I have many little stories. They are very interesting. I hope you will enjoy them. They may not be exactly like the works of the great authors, but they are your thoughts and word pictures and I am sure you will love them. Take good care of me and I will bring you many happy hours.

Previous research suggests that higher intelligence is related to better self-control, but the reasons for this link are unknown. Psychologists Noah A. Shamosh and Jeremy R. Gray, from Yale University, and their colleagues, were interested in testing the idea that certain brain regions supporting short-term memory play a critical role in this relationship.
[…]
The results show that participants with the greatest activation in the brain region known as the anterior prefrontal cortex also scored the highest on intelligence tests and exhibited the best self-control during the financial reward test. This was the only brain region to show this relation. The results appear in the September issue of Psychological Science, a journal of the Association for Psychological Science. [via PhysOrg]
A very wise educator taught me that impulsivity or the lack of ability to delay gratification reflects immaturity. He holds that children are more emotion-driven than intellect-driven, but that balance swings the other way with age. Once a person is an adult, the ability to defer gratification for a later, greater reward indicates maturity of development. This exactly correlates with the above findings,
“It has been known for some time that intelligence and self-control are related, but we didn’t know why. Our study implicates the function of a specific brain structure, the anterior prefrontal cortex, which is one of the last brain structures to fully mature,” said Dr. Shamosh [italics mine].
Here are the questions that we absolutely must ask:
- Is the ability to delay gratification solely a natural result of the chronological development of the anterior prefrontal cortex (the ability to wait develops naturally)? Or does it flow the other way, with exercise of self-control helping to mature the brain (practice makes perfect)?
- Do “external” conditions that negatively impact working memory (hormonal disruptions, physical illness, depression) also have a negative effect on self-control capacity?
- Is intelligence coincidentally correlated with the ability to delay gratification (for example, are intelligence and self-control controlled by the same brain structures?), or is there a functional relationship between the two (for example, does greater intelligence lead to greater self-control, or vice-versa?)? Alternatively, is the correlation an artifact of how we test intelligence?
And the “threatening questions” (I ought to copyright the term…):
- Does the electronic virtual environment in which so much time is spent actually inhibit or discourage the development of self-control skills?
- Could spending too much time as a child in virtual environments which usually provide instant gratification affect adult levels of intelligence?
- As a professional working to improve User Experience, is it possible that “making life easier” for people is actually doing them less of a favor than it is helping them? Am I destroying individual worlds while trying to “save the world”? (OK, I’m being a bit dramatic here, but I do feel strongly about design responsibility.)
“Greedy Mobile Interfaces”
It’s a sad but common sight in modern society – a person walking around in the world, utterly disengaged, head buried in a mobile device – a victim of the visually greedy mobile interface. […] Even the lauded and successful iPhone demands we disengage with the world and worship it’s visual luster during use.
[from Rachel Hinman’s Adaptive Path blog]
A great phrase: “greedy mobile interfaces”. When we were kids, parents went crazy from teenagers immersing themselves in Walkman earphones to the exclusion of the world around them. In fact, you might call the Sony Walkman the world’s first “greedy mobile interface”, even though it wasn’t visual. I’ve still got the original (blue and gray metal!) one that my dad brought back from Japan in a drawer here…
I didn’t know Lego Mindstorms now had an RFID module! Awesome. I’ve always wanted to get a set for myself the kids, but who knew you could play Sumo with them? And how do those little bulldozers throw salt over their shoulders without trickling it in their eyes?
Let’s go! ichi… ni…

Please, please tell me this is a joke. I’m first in line to demand a remote mobile interface… but really now…
Looking at the second page of description (see below) which claims to hook a fuel cell up to arteries and veins, I’m convinced it’s a hoax. Heck, even in the hospital they can’t leave a TPN or dialysis port open for long without risking serious system-wide infection.
Have a look at the Greener Gadgets Design Competition Site, though — there are some great ideas there (and none so gag-triggering as this one).
