Walk in Workshops | Science Gallery

The Science Gallery in Dublin provides a space to explore science, technology, and art in its multiple facets.

In June, they ran workshops “a selection of walk in workshops and a chance to test out the speed and accuracy of a penalty kick, thanks to the institute of Physics.”

Different programs included:

Bristlebot
Make a simple vibrating robot with a scrubbing brush and a small motor.

DNA Extraction
It might sound painful but all we need is a little bit of your saliva for you to actually be able to see a small amount of your very own DNA.

LED Wrist Band
Turn up in techno style at the festival season this year with this simple LED wrist band, a simple circuit using a 3 V  battery and an LED

Origami Bucky Ball
Explore the unusual construction of a Bucky Ball through the art of origami. With the simple building blocks you can build Bucky Balls out a variety of materials.

BeetleBot
A slightly more complicated robot, the BristleBot appears like it has some expensive sensory equipment enabling it to reverse away from a barrier. Find out it’s secret at this make and take.

Steven Pinker Op-Ed – Mind Over Mass Media – NYTimes

There is so much buzz right now about whether or not we’re over-saturated with technology and gizmos and electronic thingamabobs and constant electronic feedback that it’s wrecking our brains. Some people have said absolutely, 100% yes.

Steven Pinker, a language, cognitive science, evolutionary psychologist working out of MIT and most famous for popularizing the idea that language is an “instinct” or biological adaptation shaped by natural selection, however points out that in some ways electronic technologies have helped us do better science, be more creative, and build social networks.

When comic books were accused of turning juveniles into delinquents in the 1950s, crime was falling to record lows, just as the denunciations of video games in the 1990s coincided with the great American crime decline. The decades of television, transistor radios and rock videos were also decades in which I.Q. scores rose continuously.

For a reality check today, take the state of science, which demands high levels of brainwork and is measured by clear benchmarks of discovery. These days scientists are never far from their e-mail, rarely touch paper and cannot lecture without PowerPoint. If electronic media were hazardous to intelligence, the quality of science would be plummeting. Yet discoveries are multiplying like fruit flies, and progress is dizzying.

I have mixed opinions about technology and the modern world – I am a blogger, and I write for both hard-copy and online publications. Most of my paychecks have come from online writing. I gain unmeasurable knowledge and enjoyment from the Internet, and yet the most restful vacation I have had in years is three days in Boulder where the only technology I had was my cell phone and a car, both of which turned off the majority of my visit. My husband can hear the buzz of electronics at night and can’t have anything plugged in when he goes to bed.

What do you think? Any other links to people’s opinions on the subject?

The New Face of Autism Therapy | Popular Science

I found this really interesting, since 2D interactions don’t seem to teach kids to teach kids how to empathize and be more social beings. However, a 3D robot seems to do the trick…

A robotic therapist teaches kids how to read emotions

With one in 110 children diagnosed with autism, and therapists in short supply, researchers are developing humanoids to fill the gaps. But can robots help patients forge stronger bonds with people?

…There is increasing evidence that kids with autism respond more naturally to machines than they do to people. Psychologist Simon Baron-Cohen, the director of the Autism Research Center at the University of Cambridge in England, along with other autism experts, believes that robots, computers and electronic gadgets may be appealing because they are predictable, unlike people. You can pretty much guess what a computer is going to do next about 90 percent of the time, but human interactions obey very few entirely predictable laws. And this, Baron-Cohen explains, is difficult for children with autism. “They find unlawful situations toxic,” he says. “They can’t cope. So they turn away from people and turn to the world of objects.”

Digital Overload: Your Brain On Gadgets : NPR

“It’s an onslaught of information coming in today,” says Times technology journalist Matt Richtel. “At one time a screen meant maybe something in your living room. But now it’s something in your pocket so it goes everywhere — it can be behind the wheel, it can be at the dinner table, it can be in the bathroom. We see it everywhere today.”

Richtel has spent the past several months researching the toll technology and “information juggling” are taking on our lives — and our brains. His series “Your Brain On Computers” describes how multitasking on computers and digital gadgets affects the way people process information — and how quickly they can then become distracted.

Technology Review: Blogs: Mims’s Bits: Babies Take the Wheel of Driving Robots

Who knew technology could be this cute? Actually, lots of people, but I digress…

A team from Ithaca College has developed a way for babies with physical disabilities to get around and learn about their environment. It’s a motorized wheelchair, but instead of using a joystick, which is too complicated for little baby hands, all the baby has to do is rrrreeeaaccchh….. and the chair will move in that direction.

Brilliant!

It uses a Wii fit board. Read more…

Mayans had plumbing too

Everybody gets to share!
http://news.discovery.com/earth/mayan-plumbing-more-than-a-pipe-dream.html

he New World’s earliest known example of engineered water pressure was discovered by two Penn State archaeologists in the Mayan city of Palenque, Mexico.
“Water pressure systems were previously thought to have entered the New World with the arrival of the Spanish,” the researchers wrote in a recent issue of the Journal of Archeological Science. But this water feature predates the arrival of Europeans.
The city of Palenque was built around the year 100 in a constricted area with little land to build on and spread out to. By the time the city’s population hit its zenith during the Classic Maya period from 250-600, Mayans had saved precious urban space by routing streams beneath plazas using aqueduct-like structures. 
The pressurized water feature is called Piedras Bolas Aqueduct, a spring-fed channel on steep terrain.  From the tunnel’s entrance to its outlet 200 feet downhill, the elevation drops about 20 feet and its diameter decreases from 10 feet near the spring to about a half a foot where the water emerges. This combination of a downhill flow and sudden channel restriction pressurized the water, shooting it from the opening to an estimated height of 20 feet.
The researchers don’t know for sure how the Maya used the pressurized water, but they have a couple of ideas. One possibility is they used it to lift water into the nearby residential area for wastewater disposal.Another possibility, and the idea the researchers used as their model, was as a fountain.
A similar feature was found in the city’s palace.

Multi-tasking in the stone-age

Stone blades found in Sibudu Cave, near South Africa’s Indian Ocean coast, bear traces of compound adhesives that once joined them to wooden hafts to make spears or arrows.

Why is this so cool? Because by systematically replicating the ancient glues, using only Stone Age techniques and ingredients, the researchers discovered that ocher improves the bonding capacity of such natural adhesives as acacia gum. They also learned that those ingredients are highly variable in chemical composition and thus in key characteristics, such as viscosity, that affect the strength of the bond.

To make an effective glue, say the researchers, ancient artisans would have had to adjust their recipes in real time to compensate for unpredictable ingredients, staying mindful of their goal while shifting their focus back and forth among the various steps in the process.

So maybe they were just mad scientists! Mwahahaha!

TV abates loneliness

From The Frontal Cortex (the Blog):

Over at Mind Matters, there’s a cool post by Fionnuala Butler and Cynthia Picketton on the benefits of watching television when lonely, which seems to provide the same sort of emotional relief as spending time with real people:

In a recent article published in the Journal of Experimental Social Psychology, Jaye Derrick and Shira Gabriel of the University of Buffalo and Kurt Hugenberg of Miami University test what they call the “Social Surrogacy Hypothesis.”

The authors theorized that loneliness motivates individuals to seek out relationships, even if those relationships are not real. In a series of experiments, the authors demonstrated that participants were more likely to report watching a favorite TV show when they were feeling lonely and reported being less likely to feel lonely while watching. This preliminary evidence suggests that people spontaneously seek out social surrogates when real interactions are unavailable.
