17th century shamshir by Assad Ullah

Nature reports that scientists studying the technology of Damascus steel believe the material used in Arabic Medieval weapons may deserve to be regarded as an early form of nanotechnology.

Unfortunately, they seem to be unaware of the similar technology used in the Indonesian keris, or of the far more complex metallurgy of Japanese swords. And they are evidently unfortunately also unaware of the revival of Damascus steel-making by the late American knifemaker William F. Moran.

Think carbon nanotubes are new-fangled? Think again. The Crusaders felt the might of the tube when they fought against the Muslims and their distinctive, patterned Damascus blades.

Sabres from Damascus, now in Syria, date back as far as 900 AD. Strong and sharp, they are made from a type of steel called wootz.

Their blades bear a banded pattern thought to have been created as the sword was annealed and forged. But the secret of the swords’ manufacture was lost in the eighteenth century.

Materials researcher Peter Paufler and his colleagues at Dresden University, Germany, have taken electron-microscope pictures of the swords and found that wootz has a microstructure of nano-metre-sized tubes, just like carbon nanotubes used in modern technologies for their lightweight strength.

Stephen Browne spent a year working in Saudi Araba, and he observes that most Americans, including George W. Bush, don’t understand how different from us they are.

Since the beginning of the Iraq phase of this conflict of civilizations, I’ve experienced the teeth-grinding frustration of watching both pro- and anti- Iraq sides make the exact same mistake – that of supposing that these people are bascially Americans in funny costumes. In this respect, George Bush and Michael Moore are equally clueless…

In the case of the Kingdom, I went there with a certain sympathy for Arab grievances, a belief that America had earned a lot of hostility from “blowback” from our ham-handed interventionist foreign policy and support for Israel etc.

I came back with the gloomy opinion that over the long run we are going to have to hammer these people hard to get them to quit messing with Western Civilization.

Interesting article.
