During the dot-com boom, software engineers became celebrities, fêted by the press. Back in 400 B.C., another class of technicians rose to rock-star prominence: Catapult engineers. Catapults were the WMDs of the preChristian era, revolutionizing war by allowing armies to destroy city walls — and lob the flu-infected severed heads of vanquished foes back into their loved one’s front yards. Nice.
Anyway, Serafina Cuomo, of the Imperial College London’s Center for the History of Science, recently wrote a paper for Science called “The Sinews of War: Ancient Catapults”, which be the coolest title of any academic paper ever. The official term for catapult science is “belopoietics” — with poietike meaning “making of”, and belos meaning “projectile or projectile-throwing device”. Apparently, the big scientific breakthrough was when early scientists realized that all parts of the catapult were proportional to the torsion springs. Once they figured that out, they had some pretty badass stuff on their hands — as an excellent story in National Geographic News reports:
The fearsome machines terrorized battlefields and sieges until the proliferation of gunpowder. Their power was impressive and terrifying. Roman catapults could hurl 60-pound (27-kilogram) boulders some 500 feet (150 meters). Archimedes’ machines were said to have been able to throw stones three times as heavy.

From an interview with ethnobotanist and anthropologist Wade Davis:
One of the cultures you celebrate in Light at the Edge of the World is the Inuit. What do you most admire about them?
Davis: The Inuit didn’t fear the cold; they took advantage of it. During the 1950s the Canadian government forced the Inuit into settlements. A family from Arctic Bay told me this fantastic story of their grandfather who refused to go. The family, fearful for his life, took away all of his tools and all of his implements, thinking that would force him into the settlement. But instead, he just slipped out of an igloo on a cold Arctic night, pulled down his caribou and sealskin trousers, and defecated into his hand. As the feces began to freeze, he shaped it into the form of an implement. And when the blade started to take shape, he put a spray of saliva along the leading edge to sharpen it. That’s when what they call the “shit knife” took form. He used it to butcher a dog. Skinned the dog with it. Improvised a sled with the dog’s rib cage, and then, using the skin, he harnessed up an adjacent living dog. He put the shit knife in his belt and disappeared into the night.

“Video from a camp north of Toronto in December 2005 shows a car spinning around in a nearby, snow-covered parking lot. Prosecutors characterized that as special driver training but the defense, and many outsiders, said it was nothing more than “cutting doughnuts,” a favorite winter pastime of young Canadian motorists.” - A key piece of evidence submitted in the trial of a gang of alleged young Canadian terrorists.
