The Best Invention Since The Wheel

the best invention since the wheel“Between the third and seventh centuries AD, the civilizations of the Near East and North Africa gave up wheeled vehicular transportation and adopted a more efficient and speedier way of moving goods and people: They replaced the wagon and cart with the camel. This deliberate rejection of the wheel in the very region of its invention lasted for more than one thousand years. It came to an end only when major European powers, advancing their imperialistic schemes for the Near East, reintroduced the wheel.”

“The camel as a pack animal was favored over wheeled transportation for reasons that become obvious when the camel is compared with the typical ox-drawn vehicle. The camel can carry more, move faster, and travel farther, on less food and water, than an ox. Pack animals need neither roads nor bridges, they can traverse rough ground and ford rivers and streams, and their full strength is devoted to carrying a load and not wasted on dragging a wagon’s deadweight. Once the camel and ox are compared, one wonders why the wheel was ever adopted in that region in the first place.”

“A large share of the burden of goods in the Near East was always carried by pack animals. A bias for the wheel led Western scholars to underrate the utility of pack animals and overemphasize the contribution made by wheeled vehicles in the years before the camel replaced the wheel. The more we learn about the wheel, the clearer it becomes that its history and influence have been distorted by the extraordinary attention paid to it in Europe and the United States. The Western judgment that the wheel is a universal need (as crucial to life as fire) is of recent origin.”

The Sustainable Urban Dwelling Unit (SUDU)

sudu

The ‘Sustainable Urban Dwelling Unit’ (SUDU) in Ethiopia demonstrates that it is possible to construct multi-story buildings using only soil and stone. By combining timbrel vaults and compressed earth blocks, there is no need for steel, reinforced concrete or even wood to support floors, ceilings and roofs. The SUDU could be a game-changer for African cities, where population grows fast and building materials are scarce.

Timbrel Vaulting Using Cardboard Formwork

Lara Davis, Matthias Rippman and Philippe Block from the Swiss BLOCK Research Group at the ETH Zurich University have taken the centuries old timbrel vaulting technique one step further by incorporating high-tech design tools (software and CNC fabrication) and low-tech materials (cardboard boxes and wooden palettes).

Why Preserve Books?

Books in shipping containers“Digital technologies are changing both how library materials are accessed and increasingly how library materials are preserved. After the Internet Archive digitizes a book from a library in order to provide free public access to people world-wide, these books go back on the shelves of the library. We noticed an increasing number of books from these libraries moving to “off site repositories” to make space in central buildings for more meeting spaces and work spaces. These repositories have filled quickly and sometimes prompt the de-accessioning of books. A library that would prefer to not be named was found to be thinning their collections and throwing out books based on what had been digitized by Google. While we understand the need to manage physical holdings, we believe this should be done thoughtfully and well.” Read more: Why preserve books? The Physical Archive of the Internet Archive.

Castration Might Bring Us Better Politicians

Roman castration clamp“The major role of the eunuch in ancient societies was a political one. Eunuchs were the perfect guardians of harems and provided safe companions and secretaries for royal ladies. They could also be entrusted with the very highest offices of state with no fear that they would want to muscle in and start their own dynasties. Less susceptible than other men to corruption and persuasion by sexual means, they were the ideal politicians and civil servants. Their reputations could not be sullied by the accusations of rape, paternity suits and other scandals that so often blight the careers of public figures.”

“The first civilization deliberately to select eunuchs as officers of state was the Assyrian Empire, which dominated the Near East during the early first millenium BC. The practice was continued by its successors, including the Persian Empire, founded by Cyrus the Great (559-529 BC) who, according to the Greek writer Xenophon, ‘selected eunuchs for every post of personal service to him, from the doorkeepers up’. Eunuchs were becoming powerful in China during the same period. They were especially influential under the Han Dynasty (202 BC – 220 AD), when some held tremendous power simply because of their looks, and it was normal for emperors to have as many male favorites as the recommended magical number of wives. But most were of the professional variety, trained for a career in government.”

“The Roman civil service also employed eunuchs, despite the bans on castration imposed by various emperors. And, although the custom was condemned by the Church, the zenith of ‘eunuch power’ in the Roman world actually came after it was Christianized, under the Eastern Roman (Byzantyne) Empire, which ruled from Constantinople (Istanbul) between AD 395 and 1453. Thousands of young men entered public service by being castrated, providing the empire with some of its most distinguished  state secretaries, generals and even Church leaders.”
