The Pentagon (9.11.01) Memorial

Image by dbking
A Description of the symbolism inside the Pentagon Memorial……

A MEMORIAL PARK is inscribed with 184 MEMORIAL UNITS. Each and every unit is committed to an individual victim – its placement and spot within the collective field a special instance. This highly certain and qualitatively objective organizational technique yields seemingly random outcomes. The field is organized as a timeline of the victims’ ages, spanning from Dana Falkenberg, 3 years old, to John D. Yamnicky, age 71. Although each memorial unit locates itself on its respective age line, the units are then organized by birth date along the age line. Inherent tendencies – the clustering of specific age groups, the gap among the children and adults – are clearly evident and meaningful, although infinitely interpretive.

Private interpretation is further sparked by embedding layers of specificity into the orientation of each and every memorial unit inside the expansive web site. Fifty-nine memorial units face one particular direction, 125 face the other – as a result distinguishing victims on board American Airlines Flight 77 from those who had been inside the Pentagon. When going to a memorial committed to a victim who was in the Pentagon, the visitor will see their engraved name and the Pentagon in the very same view. Conversely, one would see the engraved name of a victim on Flight 77 with the sky. Although extremely particular, this distinction is really subtle when deployed regularly throughout the web site. It adds a level of difference to the visual and spatial field, therefore provoking visitors’ curiosity, although simultaneously telling the story of those involved in the events that took place here that day.

Elegant in its self-supporting kind, the memorial unit is at after a glowing light pool, a cantilevered bench and a place for the permanent inscription of every single victim’s name. Employing Laptop Numerically Controlled (CNC) technologies typical to the aerospace market, the cast duplex stainless steel memorial unit is easily mass-made and extremely articulate. Its structural cross-section not only reflects radiant light from the glowing pool of water onto the surrounding gravel field, but also permits that fields to be continuous. A polymer concrete utilizing the identical gravel aggregate located on the ground is poured into the memorial unit, seemingly “freezing” the gravel in spot and floating it above the light pool. This surface is polished smooth to attain a “terrazzo” finish. As the memorial unit grows out of the ground, the stabilized gravel field is interrupted only by moments of glowing light and water, and the engraved names float above these moments.

Though loose sufficient to hear and really feel footsteps upon it, stabilized gravel is a hard, ADA-compliant surface. Disbursed all through the complete website, the porous stabilized gravel field is contained within two perimeter benches that serve as planters for ornamental grasses. These grasses act as a soft screen demarcating the boundary of the memorial park. Further, the combined length of the perimeter benches plus the bench portion of each and every memorial unit supplies more than two,100 linear feet of seating surface. Birth years, utilized to find the age lines, are inlaid stainless steel numbers set flush with the finished horizontal surface of the perimeter benches. The birth years are flanked by the stainless steel age lines that permeate the whole internet site.

The western edge of the site is defined with the AGE WALL – a wall that “grows” in height one inch per year relative to the age lines that organize the site at big. As one moves deeper into the website the wall gets higher – it grows from 3 inches above the perimeter bench (at Dana’s memorial age-line) to 71 inches above the bench (at John’s). Strategically, this wall grows as a barrier is required among the memorial park and the delivery lane that encroaches upon the web site at its northwestern edge. Experientially, this wall communicates the organizational technique to the drivers passing by on the freeway, while still enabling them to peer into the site from afar. From within the internet site it supplies a shadowy backdrop for the lacy ornamental grasses that are planted along its base.

A vivid canopy of colour and light gives shade all through the web site, as trees are clustered in conjunction with the disbursement of memorial units. Numerous Maple species, specially the Paperbark Maple (Acer griseum) serve this scheme nicely. The Paperbark is one of the last Maples to drop their leaves, retaining their beautiful fall foliage properly into the winter months – this suspension of time will contribute to the sublime beauty of the Park. Upon maturity, the cinnamon-colored bark starts to exfoliate, exhibiting exquisite texture and colour and all round year-round interest. On an intimate level, the interplay amongst leaves, light, bark, gravel, grasses, water, and the senses will be greatly enhanced with these sophisticated trees.

Take my Lightning but Don’t Steal my Thunder – Covent Garden

Image by Dave Pearce (London)
This surreal stunt is the function of 30-year-old artist Alex Chinneck, master of architectural illusion, who has previously turned buildings upside down, pulled off their facades, and let them slither down in a heap on the pavement. A Uri Geller of bricks and mortar, this is 1 of his most ambitious functions yet, fabricating an imaginary eastern entrance to the market hall that he’s then torn in half and jacked aloft, its Portland stone columns and granite walls left brutally severed.

“I wanted to play on the theatricality of this area, and make some thing physically extraordinary,” he says. In location for the subsequent 3 weeks, it is currently attracting crowds of gawping passers-by, as a visually arresting one particular-liner, seemingly made for the Instagram era.

The illusion of weightlessness is created feasible by a lot of polystyrene and 16 tonnes of steel. A 12-metre armature hidden inside the structure is connected to the ground by way of an innocuous marketplace cart, in which a 6-tonne counterweight stops it all from toppling more than. The effect of weathered stonework has been immaculately recreated by Richard Nutbourne and his team of scenic artists – who normally work on stage sets for the opera and ballet next door. Covering the CNC-milled polystyrene blocks with plaster and granite sand, they have mimicked the neighbouring gnarled stone even down to the detail of moss, electrostatically flocked onto the surface.

“My perform is typically very straightforward in its idea,” says Chinneck, “but it’s a nightmare in execution.” Eight months in the generating, the Covent Garden installation is the product of a one hundred-powerful team of architects and engineers, carpenters and set-builders, and much more than 500 hours of digital carving. It follows earlier commissions in the piazza from Jeff Koons and Damien Hirst, Banksy and Sam Taylor-Johnson.

FROM PLANET EARTH

Image by jurvetson
On July 16, 1969, Apollo 11 took flight to the moon. In the days that preceded the launch, the U.S. scrambled to pull together the messages from Earth that would be left behind on the moon. This is the Apollo Goodwill Disc, and it was engineered to last lengthy following the U.S. flag was destroyed.

This silicon disc includes etched letters (scanned and reduced 200x) from the leaders of the world’s nations. This is one of the discs created by Sprague and retained by a Sprague manager a second resides in the Smithsonian, and a third rests on the Moon’s Sea of Tranquility, deposited there by Buzz Aldrin.

(Does anybody know if other builds remain intact? A Sprague press release says that of the handful of discs made, a single was given to President Nixon and 1 to President Johnson).

It is a tricky topic matter for photography. I wanted to capture the angle-dependendent iridescence of the semiconductor thin films. The overhead light source reflects off the leather seat cushion, revealing the shift from green to purple that happens at oblique angles.

This comes from the early days of the semiconductor market, when Apollo consumed 50% of international production, and wafers had been just 2” wide (the ultimate disc was cropped around the 1.5” metallized ring and placed in a aluminum case).

The notion of using lithographic thin films to produce a extended-term option to microfiche was novel at the time, earning Sprague a patent (#3,607,347). I used those techniques to develop a multi-colored Devo hat on a chip I designed at HP in 1988.

The story of the rushed creation of the disc is fascinating, as are the messages embedded in this interplanetary time capsule.

The notion started in June, 1969, and it was a politically charged project, in the midst of the Cold War and the Vietnam War. On June 27, NASA telephoned the state division, and got the unprecedented permission to make contact with the foreign chiefs of state to deposit a message on the moon. This was 19 days before launch. They had been asked to compose and send typed and scribed letters to the U.S. (they came by telegram and mail).

But NASA did not know how they would shop the messages so that they could last thousands of years in the harsh temperatures, solar radiation, and cosmic rays on the lunar surface. So they approached the supplier of some of the most sophisticated technologies on Apollo – the nascent semiconductor business.

Sprague manufactured 53,000 components on the Apollo 11 spacecraft and many much more for the ground assistance equipment. The engineers chose silicon for the storage medium since of the density of storage and the stability of silicon more than temperature in a vacuum.

“Crash course is an understatement. We had practically no time to put this together!”
— John Sprague, head of the semiconductor division

NASA officials delivered the goodwill letters on the July 4 vacation, and Sprague finished the first printing on July 5 at three a.m. Each and every letter was photographed, and optically reduced to the point where every single letter was ¼ the width of a hair. The image was transferred to a glass photomask which was then employed to image the silicon, considerably like the early days of IC manufacturing.

“It was a rush to get it accomplished. We slept on lab benches for two days in a row.”
— Ray Carswell, Sprague Engineer

Nevertheless, on July 9, the business was asked to commence over and develop a new disc with eight added messages. It was completed and sent to Houston at 3:30 a.m. on July 11, five days prior to launch.

In the comments under are some of the messages that caught my eye, such as the Vatican and Estonia (recognized in spite of their Soviet occupation at the time).

The letters had been written independently at a historic epoch in exploration abroad and conflict at home. Most of them reference God or peace on Earth.

“The Silicon disc represents a historic time when many nations looked beyond their variations to come with each other to accomplish this historic first.”
Charlie Duke, Apollo 16 moonwalker
