Just how heavy and cumbersome was medieval armor? Who wore it? What did it look like? To find out, watch How to Mount a Horse in Armor and Other Chivalric Problems, an entertaining, informative, and deliciously snarky presentation by Dirk H. Breiding, assistant curator of the Department of Arms and Armor at the Metropolitan Museum of Art in New York. [more inside]
A few examples of high-quality re-creations of medieval armor. Much of this is created using historical techniques (youtube,) by men (slightly NSFW) who can only be called masters. But it ain't cheap. [more inside]
Wierd tanks: Tank design has pretty much come to the point where all tanks are alike. They are mostly 60 ton machines with single turret with a 120-125 mm main gun. A number of different approaches has been tried through history, tough. One is the the heavy multiturreted Soviet T-35 from the 30s. Another take is the Swedish S-tank from the 60s, which did away with the turret altogether. A bit more conventional, but pretty much a one-nation tailor-made design is the Israeli Merkava, which is balanced heavily in favour of crew survivability with the engine in front and the ability to carry along a few infantrymen. The strangest of the bunch is the Russian WWI Czar tank, but just a tad impractical, standing 9 meters tall.
It's in the mail. Dylon Whyte's Art of Chainmail site features beautiful, clear renderings showing, step-by-step, how to join chain links to form different mail patterns, including European, Japanese, and (probably-not-)Persian designs. This is actually fascinating stuff even if you're not a medievalist or a Renaissance-faire type. Also, from the same source, a brief history of armour and the the secret behind the chain bra!
