How Far Back?
August 31, 2009 by Filed Under: History, Quotes, Steampunk, Technology
On the appeal of steampunk:
“Compared with an earlier and more thoroughly handcrafted era, a return to the late 1800s or early 1900s does not mean having to give up all the most basic modern conveniences. Most of these, including indoor plumbing, electric lighting and even air conditioning, had been invented and put into use by this time—in the main by the privileged, but then it is their lives (and not those of common men and women) that are the stuff of historical fantasy. Travel no longer meant riding in cramped stagecoaches over dirt roads or wind-and wave-tossed sailing vessels, but in luxurious automobiles
and handsomely appointed cabins aboard trains and steamships.”

Polynesian Stick Charts
July 8, 2009 by Filed Under: History, Maps, Navigation, Travel
“The Polynesians, scattered as they were over 1,000 islands across the central and southern Pacific Ocean, were master navigators who tracked their way over huge expanses of ocean without any of the complex mechanical aids we associate with sea fairing. They didn’t have the astrolabe or the sextant, the compass or the chronometer. They did however have aids of a sort, which though seemingly humble, were in fact the repositories of an extremely complex kind of knowledge. Called Rebbelibs, Medos. and Mattangs, today we call them simply Stick Charts.” Via Tecob. Related: Satellite navigation in the 18th century.

Prison Treadmills

The prison treadmill was invented in England in 1817 by Sir William Cubit, who observed prisoners lying around in idleness and put himself to the task of “reforming offenders by teaching them habits of industry.” Forty-four prisons in England adopted it as a form of hard labour that could also grind grain (although some treadwheels were only “grinding the wind“).
The punitive treadmill was then implemented in America for two long years, between 1822 and 1824, at Bellevue penitentiary outside New York. Prisoners stepped on the mill for 10 hours a day (with 20 minute breaks per hour), grinding grain, often with a large audience of jeering onlookers housed in a specially built viewing house.

Man versus nature
May 3, 2009 by Filed Under: Environmentalism, History
“The object of the present volume is: to indicate the character and, approximately, the extent of the changes produced by human action in the physical conditions of the globe we inhabit; to point out the dangers of imprudence and the necessity of caution in all operations which, on a large scale, interfere with the spontaneous arrangements of the organic or the inorganic world; to suggest the possibility and the importance of the restoration of disturbed harmonies and the material improvement of waste and exhausted regions; and, incidentally, to illustrate the doctrine, that man is, in both kind and degree, a power of a higher order than any of the other forms of animated life, which, like him, are nourished at the table of bounteous nature.”
