Engineering and Technology History Wiki
> The ETHW is not a “how-does-technology-work” site. The scope of the ETHW is historical; instead of focusing on the inner workings of technology, it aims to explain how the technology was developed, who were the major players involved, and what long term significance the technologies have. The ETHW is not only an encyclopedia of the history of technology, but it also contains a full range of materials that relate to the legacy of engineering, including personal accounts, documents, and multimedia objects. In that sense, it is a combination reference guide, blog, virtual archive, and on-line community.
Animated optical illusions. These are very nice.

George III's collection of military maps
> George III’s collection of military maps comprises some 3,000 maps, views and prints ranging from the disposition of Charles V’s armies at Vienna in 1532 to the Battle of Waterloo (1815).
> Most notable among these are the military maps, prints and drawings collected by his uncle, William Augustus, Duke of Cumberland (1721–65), particularly during his period as Captain General of the British army during the War of the Austrian Succession (1743–8) and the Seven Years War (1756–63).
> The second major collection, bought by George III in 1763, was that of the military prints collected by the Italian art patron, Cassiano dal Pozzo (1588–1657). In addition to these, George III acquired hundreds of maps of contemporary conflicts, such as the American War of Independence (1775–83), and the French and Napoleonic Wars (1792–1815).

The 3 A.M. Phone Call
> It went to a national security adviser, Zbigniew Brzezinski, who was awakened on 9 November 1979, to be told that the North American Aerospace Defense Command (NORAD), the combined U.S.–Canada military command–was reporting a Soviet missile attack. Just before Brzezinski was about to call President Carter, the NORAD warning turned out to be a false alarm. It was one of those moments in Cold War history when top officials believed they were facing the ultimate threat. The apparent cause? The routine testing of an overworked computer system.

Abstract Aerial Art
> Taken from a top-down perspective, every aerial photograph we take is of a real place on our planet. We like to compose our images as artworks rather than traditional photographs. Other than slight colour and contrast enhancements none of our images are manipulated in any way. As we always say, “the point is not to work out what it is, but to show how weird and wonderful the world can look from above”.
Prints for sale, but free to look.

Iconic consoles of the IBM System/360 mainframes, 55 years old
> The IBM System/360 was a groundbreaking family of mainframe computers announced on April 7, 1964. Designing the System/360 was an extremely risky “bet-the-company” project for IBM, costing over $5 billion. Although the project ran into severe problems, especially with the software, it was a huge success, one of the top three business accomplishments of all time. System/360 set the direction of the computer industry for decades and popularized features such as the byte, 32-bit words, microcode, and standardized interfaces. The S/360 architecture was so successful that it is still supported by IBM’s latest z/Architecture mainframes, 55 years later.
> The lower part of the Model 30 console was used for operator intervention. Note the binary-to-hexadecimal conversion chart below the hexadecimal dials.

A Huge Collection of Apollo 11 Press Kits
> When Apollo 11 landed two men on the Moon and returned them safely to Earth, thousands of people at NASA were joined in the effort by dozens of companies that did everything from building the spacecraft to providing the cameras for the mission. Each of those companies was understandably proud of their involvement and wanted to use the mission to drum up interest in their products and services. Marketing strategist David Meerman Scott has been collecting the press kits produced by the Apollo contractors and has made them available online for free download in PDF format.

Explaining Code using ASCII Art
> People tend to be visual: we use pictures to understand problems. Mainstream programming languages, on the other hand, operate in an almost completely different kind of abstract space, leaving a big gap between programs and pictures. This piece is about pictures drawn using a text character set and then embedded in source code. I love these! The other day I asked around on Twitter for more examples and the responses far exceeded expectations (thanks everyone!). There are a ton of great examples in the thread; here I’ve categorized a few of them. Click on images go to the repositories.
