In 1995 Stewart Brand, founder of The Whole Earth Catalog (described by Steve Jobs as “Google in paperback form, 35 years before Google came along”) wrote a book about how buildings adapt to the changing world around them, called How Buildings Learn. Brand also made a 6-part documentary with the same name as his book, which was produced in 1997 by the BBC. Open Culture has posted the series on its website. Music is by Brian Eno.

's gorgeous and haunting photo series and book, Soviet Ghosts: A Communist Empire in Decay
, documents abandoned towns, factories, prisons, hospitals, theaters, and military bases in the Soviet Union and former Eastern Bloc.
Whilst some may look at the decay in these places as simply reflecting the destruction of the Soviet Union and the moral bankruptcy of a flawed ideological system. In reality they will cease to exist very soon and as the memories fade, these places and the communities who once gave life will be forgotten and deserve to be recorded for posterity too. This book documents the strange interval caught between modernity and antiquity.

A London man blames a new 37-story skyscraper under construction for melting his Jaguar. Apparently, sunlight reflected off the building, known as the "Walkie-Talkie," and melted parts of the car. According to the BBC News, the construction company left a note on the man's car and paid for repairs. The City of London has closed three parking spots as a precaution while the situation is under investigation. This reminds me of the Mythbusters' "Archiemedes Death Ray" episode which I happened to have just watched again yesterday! Read the rest
A privately-built villa, surrounded by imitation rocks, is pictured on the rooftop of a 26-floor residential block in Beijing. Construction on the residence took six years, and the huge dwelling offers 1,000 square meters of living space. Residents in the building complained about the villa and its perch, according to the Xinhua News Agency, fearing that the agglomeration's weight may cause the building beneath it to collapse. The local bureau of city administration attempted to investigate the allegedly illegal construction, but the owner "has not shown up so far." (Photo: Jason Lee, Reuters) Read the rest
Architects are turning an old cold storage facility into modern office buildings. But first, they have to thaw it out.
What construction crews could learn from your high school science class, and more great earth science videos.
Exit signs are so ubiquitous that they're almost invisible. Every public building has them. In fact, they are so common that, taken together, these little signs consume a surprisingly large amount of energy.
Each one uses relatively little electricity, but they are on all the time. And we have a lot of them in our schools, factories, and office buildings. The U.S. Environmental Protection Agency estimates that there are more than 100 million exit signs in use today in the U.S., consuming 30–35 billion kilowatt-hours (kWh) of electricity annually.
That’s the output of five or six 1,000 MW power plants, and it costs us $2-3 billion per year. Individual buildings may have thousands of exit signs in operation.
To put this into a bigger context: This is just one small part of what makes buildings, in general, incredibly energy intense. In the United States, we use more energy powering our buildings—from the lights, to the heating, to the stuff we plug into the walls—than we use to do anything else. Because of that (and because of the fact that electricity is mostly made by burning coal or natural gas) buildings produce more greenhouse gas emissions than cars.

It sure seems like a completed structure at first glance. But look closer. Specifically, look at the piles of stone blocks stacked on top of the columns.
Those blocks were hauled up there during construction—around the turn of the 20th century. They were supposed to be carved into sculptures representing "Music", "Architecture", "Painting" and, ironically, "Sculpture". Instead, the stone has sat there for 110 years, through two major renovations, un-carved and largely ignored.

Yesterday was the 110th anniversary of air conditioning. The building pictured above—1040 Metropolitan Ave. in the Williamsburg neighborhood of Brooklyn, New York—was the first building in the world to enjoy the luxury of cold air blowing on a blisteringly hot day.
A junior engineer from a furnace company figured out a solution so simple that it had eluded everyone from Leonardo da Vinci to the naval engineers ordered to cool the White House when President James A. Garfield was dying: controlling humidity.
The junior engineer who tackled the problem was Willis Carrier, who went on to start Carrier Corporation. The solution he devised involved fans, ducts, heaters and perforated pipes ... Carrier’s plan was to force air across pipes filled with cool water from a well between the two buildings, but in 1903, he added a refrigerating machine to cool the pipes faster.
It's a neat technological story, and as the New York Times piece points out, Carrier's invention wasn't just about making people comfortable. In the beginning, it was about allowing a specific job to get done even when the weather was hot. In fact, air conditioning is still the tool that makes things like computers possible, by creating dust-free, low-humidity clean rooms where the parts can be manufactured.

How do engineers know that the pillars supporting a bridge can withstand the force of thousands of cars driving over them for decades? How do we know what would happen to that bridge during an earthquake? What about an earthquake in winter?
Buildings, roads and bridges are all designed with a buffer of safety—basically, engineers round up on the numbers, a lot, and design these things to be far more sturdy than they actually have to be. But to make those decisions, they first have to know the physical limits of the materials they're working with. The best way to do that: Take a scaled version of a girder, pillar, or concrete slab and push it past the breaking point. Yes, this is, in fact, as awesome as it sounds.
The Constructed Facilities Laboratory at North Carolina State University is one of the places in the United States where this kind of research happens. In this lab, engineering researchers shake, bend, freeze, and crush the stuff that supports our world. I got to take a tour of this lab back in January, led by lab manager, Greg Lucier.
The videos here will take you through the 4500-square-foot lab and introduce you to the equipment these engineers use—from giant compression machines to something called a "Thermotron environmental chamber."
We'll start with a quick spin around the lab, just to get acquainted with the space. Then, you'll learn how some of the systems you see here work and why they're so important. Read the rest
Anechoic chambers are pretty damn awesome. Basically, they're rooms designed to be sound-proofed against outside noise, while, inside, sound is prevented from bouncing off the walls. There's no echo. There's a number of ways you can build this, but one system at the University of Salford in England, is actually a room within a room, with the innermost chamber actually mounted on springs, rather than the floor of the outer room.
Anechoic chambers are often used to test out audio equipment or to get accurate audio measurements on systems that are supposed to operate very quietly.
Minnesota Public Radio recently went inside the room that holds the title for world's quietest—an anechoic chamber at Orfield Laboratories in Minneapolis.
To get into the anechoic chamber, you go through two bank vault-like doors. The floor in the room is mesh like a trampoline so there's nothing on the floor for the sound to bounce off of. The walls are lined with sound-proofing wedges that are a meter long so they absorb the sound.
...A typical quiet room you sleep in at night measures about 30 decibels. A normal conversation is about 60 decibels. This room has been measured at -9 decibels.

Still think that something other than a mere plane crash brought down the World Trade Center towers? According to a Norwegian materials expert, you may be right. Just ... you know ... not in the way most Truthers probably expect.
Christian Simensen thinks the Twin Towers were ultimately felled by a thermite reaction.
"If my theory is correct, tonnes of aluminium ran down through the towers, where the smelt came into contact with a few hundred litres of water," Christian Simensen, a scientist at SINTEF, an independent technology research institute based in Norway, said in a statement released Wednesday.
"From other disasters and experiments carried out by the aluminium industry, we know that reactions of this sort lead to violent explosions."
Given the quantities of the molten metal involved, the blasts would have been powerful enough to blow out an entire section of each building, he said.
This, in turn, would lead to the top section of each tower to fall down on the sections below.
The sheer weight of the top floors would be enough to crush the lower part of the building like a house of card, he said.
I honestly don't know how plausible an idea this is. It sounds reasonable to a layperson, but I'm curious what those of you with more engineering expertise think.
The AFP has a write-up about the theory. There's also a more-detailed explanation on the website of SINTEF, the Norwegian research lab where Simensen works. Finally, this appeared in the trade journal Aluminum International Today, and they've got an email address where you can request a copy of the story. Read the rest
