Check out the new glowing art installation coming to Madison Square Park: TIME OUT New York



Public art installations at Madison Square Park do not mess around.

This summer, renowned artist Josiah McElheny brought a trio of glass sculptures to the space for his Prismatic Park installation. Last year, a set of life-size gingerbread houses set up shop there during the holiday season. Heck, even a giant inflatable banana that was more of an advertisement for Chiquita than a work of art had the internet buzzing about the park last month.


This fall, a new installation from Erwin Redl will head to the park's Oval Lawn. Titled Whiteout, the piece looks like something straight out of Star Wars. The project is made up of hundreds of white, transparent spheres that encapsulate white LED lights, which will be suspended from a grid of poles and cabling. The “orbs” will dangle two feet off of the ground, swaying with the wind. Redl is also programming the spheres to light up in a trippy pattern, producing a wave-like visual across the lawn. 


The exhibit will be on view from November 16 through April 15, 2018.


Madison Square Park:



This public space was a highly desirable address when it opened in 1847, and is now a verdant oasis. It hosts art installations, food festivals and a popular series of summer concerts. The destination is also home to Shake Shack, a summer favorite (as evidenced by the shockingly long lines) for burgers, fries and, of course, shakes.

SEEING WITH YOUR TONGUE: Sensory-substitution devices help blind and deaf people, but that’s just the beginning.

According to one scientist, "You don't see with your eyes, you see with your brain."

The climbers at Earth Treks gym, in Golden, Colorado, were warming up: stretching, strapping themselves into harnesses, and chalking their hands as they prepared to scale walls stippled with multicolored plastic holds. Seated off to one side, with a slim gray plastic band wrapped around his brow, Erik Weihenmayer was warming up, too—by reading flash cards. “I see an ‘E’ at the end,” he said, sweeping his head over the top card, from side to side and up and down. “It’s definitely popping—is it ‘please’?” he asked me. It was. Weihenmayer moved triumphantly on to the next card.


Erik Weihenmayer is the only blind person to have climbed Mt. Everest. He was born with juvenile retinoschisis, an inherited condition that caused his retinas to disintegrate completely by his freshman year of high school. Unable to play the ball games at which his father and his brothers excelled, he took to climbing after being introduced to it at a summer camp for the blind. He learned to pat the rock face with his hands or tap it with an ice axe to find his next hold, following the sound of a small bell worn by a guide, who also described the terrain ahead. With this technique, he has summited the tallest peaks on all seven continents.

A decade ago, Weihenmayer began using the BrainPort, a device that enables him to “see” the rock face using his tongue. The BrainPort consists of two parts: the band on his brow supports a tiny video camera; connected to this by a cable is a postage-stamp-size white plastic lollipop, which he holds in his mouth. The camera feed is reduced in resolution to a grid of four hundred gray-scale pixels, transmitted to his tongue via a corresponding grid of four hundred tiny electrodes on the lollipop. Dark pixels provide a strong shock; lighter pixels merely tingle. The resulting vision is a sensation that Weihenmayer describes as “pictures being painted with tiny bubbles.”

Reading the cards before his climb helped Weihenmayer calibrate the intensity of the electrical stimulation and make sure that the camera was pointing where he thought it was pointing. When he was done, he tied himself into his harness and set off up Mad Dog, a difficult route marked by small blue plastic holds set far apart on the wall. Without the BrainPort, Weihenmayer’s climbing style is inelegant but astonishingly fast—a spidery scramble with arms and feet sweeping like windshield wipers across the wall in front of him in order to feel out the next hold. With the device on his tongue, he is much slower, but more deliberate. After each move, he leans away from the wall, surveys the cliff face, and then carefully reaches his hand out into midair, where it hovers for a split second before lunging toward a hold several feet away. “You have to do the hand thing, because it’s hard to know where, exactly, things are in space,” Weihenmayer explained, as I prepared to tackle Cry Baby, a much simpler route. “Once my hand blocks the hold, I know I’m in front of it, and then I just kind of go in there.”

Weihenmayer told me that he wouldn’t take the BrainPort up Everest—relying on fallible electronics in such extreme conditions would be foolhardy. But he has used it on challenging outdoor climbs in Utah and around Colorado, and he loves the way that it restores his lost hand-eye co√∂rdination. “I can see the hold, I reach up, and I’m, like, ‘Pow!’ ” he said. “It’s in space, and I just grabbed it in space. It sounds so simple when you have eyes, but that’s a really cool feeling.”,

The BrainPort, which uses the sense of touch as a substitute for sight, is one of a growing number of so-called sensory-substitution devices. Another, the vOICe, turns visual information into sound. Others translate auditory information into tactile sensation for the deaf or use sounds to supply missing haptic information for burn victims and leprosy patients. While these devices were design,d with the goal of restoring lost sensation, in the past decade they have begun to revise our understanding of brain organization and development. The idea that underlies sensory substitution is a radical one: that the brain is capable of processing perceptual information in much the same way, no matter which organ delivers it. As the BrainPort's inventor, the neuroscientist Paul Bach-y-Rita put it, "You don't see with your eyes, you see with your brain."

Bach-y-Rita, who died in 2006, is known as the "father of sensory substitution," although as he liked to point out, both Braille and white canes are essentially sensory-substitution systems, replacing information that is typically visual -- words on a page, objects at a distance -- with tactile sensation. He even argued that writing ought to be the original precursor, because it enabled the previously auditory experience of the spoken word to be presented visually......

It's fascinating, isn't it?

I noticed after having yogurt for breakfast that even while eating, I was taken at how diluted it was compared to the same yogurt 20 years ago. Wholeheartedly agree with this concept.

Incredible the blind and deaf will be able to enjoy all that the planet and its inhabitants have to offer.

This Tiny Device Could Provide Clean Water for 663 Million People





A tiny, black rectangular device could be the world’s long-term solution for clean water.  The gadget is solar-powered, half the size of a postage stamp, and it disinfects water.

“Our device looks like a little rectangle of black glass,” said Chong Liu, lead author of a paper on the device published in 
Nature Nanotechnology. “We just dropped it into the water and put everything under the sun, and the sun did all the work,” she said.

With
663 million people in the world not having access to clean water, a device this efficient stands to significantly change many lives. Roughly 800 children die a day due to lack of access to clean water.

The purifier, developed by researchers at the SLAC National Accelerator and Stanford University, contains microscopic layers of “nanoflakes.” When exposed to water and sunlight, they produce hydrogen peroxide, a natural disinfectant. In early testing, the disinfectant killed 99.999% of bacteria before dissipating and leaving behind safe-to-drink water.

“When you see there’s no bacteria growing, it’s really exciting,” said Liu in the report published on Monday. “We didn’t expect it to work that well at first.”

The new device is a substantial improvement over previous solar-powered water cleaning systems. The nanoflakes, which contain industrial lubricant molybdenum disulfide, absorb more than just UV light. Absorbing a wider band of the light spectrum means the nanoflakes utilize 50% of the incoming sunlight’s energy, whereas standard purifiers harness 4%.





The solar-powered reaction should leave the device completely reusable.

Researchers tested the tiny tablet in 25-milliliter vessels containing E. Coli and lactic acid bacteria Enterococcus. It took less than 20 minutes for the water in the container to be cleaned. Larger water tanks can be purified by scaling up the number of tablets used.

For the moment, the still-unnamed device’s ability to clean chemical pollutants like lead is unknown.
Despite the potential limitation, the small rectangle of nanoflakes is a major step forward to providing everyone in water-contaminated areas with a clean source of refreshment.

“As a researcher it’s really exciting for us to see that by developing technologies you have the potential to help a lot of people,” Liu said.

The device will next be tested in real world settings before, researchers hope, being put into commercial production at a price less than $30.

THE TELEPHONE NUMBER - Happy Valentine's Day!


FADE IN:

INT. BEDROOM. APARTMENT - NIGHT

MIKE frantically fingers the contents of his wallet.

MIKE
Where is that business card?

He holds his wallet upside down, watching the waterfall of its contents cascade to his unmade bed.

MIKE
It was blue.

For the next half hour he inspects each item, discarding the unnecessary. Still, no blue business card. Despondent, he falls onto his bed; the loss of the card summing up his chaotic life.

MIKE
Think, Mike. Think.

He closes his eyes and concentrates. The first three numbers lept before him as he'd studied her telephone number countless times. But the last four...as a child repeats the alphabet to reach an elusive letter, so he tried with numbers.

MIKE
One, two, three... Three!

Scrambling for a notepad, he proceeds until seven digits stared back at him; the telephone number he could swear he'd had all along. His digital clock blares eleven o'clock.

MIKE
It's pretty late.
(pumping himself)
It's now or never!

As he dials, he visualizes the tall, slender blonde in her slinky, red dress, flirting over a martini.

MIKE
But I'm not in her league.

While the phone rings, he reminds himself that he wasn't half bad looking, and women even commented on how his glasses made him look just as adorable as Clark Kent.

MIKE
Just as clumsy, too.

A woman answers the phone.

WOMAN (OFFSCREEN)
Hello?

MIKE
Hello? Danielle?

DANIELLE (OS)
Yes?

MIKE
Um. This is Mike. You may not remember...

DANIELLE (OS)
(surprised)
I didn't think you'd ever call, Mike.

MIKE
(spirits soaring)
Would you like to go out for dinner?
You would? I mean, Saturday? Seven thirty?
Sure, I know where it is. Terrific! See you
then. Good night, Danielle.

He dances victoriously around the bedroom, then collapses onto his bed, soon falling asleep.

SEVERAL DAYS LATER

Mike rushes haphazardly, changing his Hanes underwear at least a dozen times. He would be late if he didn't step up his already frenetic pace.

INT. RESTAURANT - NIGHT

Mike follows the maitre d' who escorts him to a cozy table in the dimly lit corner at which sits a lovely, bespectacled young woman.

DANIELLE
(adjusting her glasses)
Mike?

MIKE
(mimics her)
Danielle?

While the excitement and anticipation hisses from his ego, Danielle grins.

DANIELLE
Seems there's been a little mistake.

Her embracing smile emphasizes her gentleness and sweet face.

DANIELLE
It doesn't mean we can't make the best of it.
What do you think?

MIKE
(grins sheepishly)
Sure.

After ordering, then pouring the wine, he slowly shares what had happened. Danielle's LAUGHTER, both comforting and lilting, eases his self-consciousness. The hours fly by. When they realize they're the last couple in the restaurant, they exchange warm glances.

MIKE
I'd love to see you again.

DANIELLE
I would too, Mike, but under one condition.

MIKE
What's that?

DANIELLE
(holding his hands)
You give me your telephone number.

MIKE
(chuckles)
Agreed.

INT./EXT. RESTAURANT - NIGHT

As they walk into the crisp spring night, DANIELLE's tresses bounce in sync with Mike's newfound spring in his step.

MIKE
(to himself, glancing at the stars)
Am I glad I lost that business card!

FADE TO BLACK
