The histo ry o f flying is a goo d example to loo k at in detail fo r insight into the interactio n o f techno lo gy with human affairs, because two radically different techno logies were co mpeting fo r survival- in the beginning they were called heavier-than-air and lighter-than-air. The airplane and the airship…
The rocket equation contains three variables. Given any two of these, the third becomes cast in stone. Hope, wishing, or tantrums cannot alter this result. Although a momentum balance, these variables can be cast as energies. They are the energy expenditure against gravity (often called delta V or the change in rocket…
“The progress of religion is defined,” writes the early-twentieth-century philosopher Alfred North Whitehead, “by the denunciation of gods.” Gods become fewer in number until there is only one—or a Father, Son and Holy Ghost adding up to one. And the qualities of the lonely God that is left are also denounced. He…
Midway through her 9 a.m. Intro to American Literature course Thursday, University of Nebraska-Lincoln Professor Elizabeth Mabrey suddenly realized that her students would accept, without question, literally any words that came out of her mouth as absolute, incontrovertible fact, sources confirmed. “I could say that…
Perhaps the best way to describe the flawed vision of fin de siecle futurists is to say that, with few exceptions, they expected the coming of an ''immaculate'' economy -- one in which people would be largely emancipated from any grubby involvement with the physical world. The future, everyone insisted, would bring an…
In fact, a physics colleague, Mark Srednicki of U.C. Santa Barbara, brought to my attention a much greater gaffe in one episode, in which sound waves are used as a weapon against an orbiting ship. As if that weren't bad enough, the sound waves are said to reach “18 to the 12th power decibels.” What makes this…
Have you tried neuroxing papers? It's a very easy and cheap process. You hold the page in front of your eyes and you let it go through there into the brain. It's much better than xeroxing.
Coleridge pointed to this difference between an organising taxonomy and a dynamic scientific principle or law in essays in The Friend (1819). The psychology of collecting, ordering and naming specimens could also be seen as a form of mental colonising and empire-building. ‘Taxonomy after all, is a form of imperialism…
Imagine, say, that you wanted to travel from New York to Madrid, two cities that are at almost the same latitude. If the earth were flat, the shortest route would be to head straight east. If you did that, you would arrive in Madrid after traveling 3,707 miles. But due to the earth's curvature, there is a path that on…
And think about failure modes—I remember one of the great lessons I got about programming was when I showed up at the airport at Heathrow, and there was a power failure and none of the computers were working. But my plane was on time. Somehow they had gotten print-outs of all the flights. 1 don't know where—there must…
In the Solomon Islands, as many people know, the natives didn't understand the airplanes which came down during the war and brought all kinds of goodies for the soldiers. So now they have airplane cults. They make artificial landing strips and they make fires along the landing strips to imitate the lights and this…
