| I have sacrificed time, health, and fortune, in the desire to complete these Calculating Engines. I have also declined several offers of great personal advantage to myself. But, notwithstanding the sacrifice of these advantages for the purpose of maturing an engine of almost intellectual power, and after expending from my own private fortune a larger sum than the government of England has spent on that machine, the execution of which it only commenced, I have received neither an acknowledgement of my labors, not even the offer of those honors or rewards which are allowed to fall within the reach of men who devote themselves to purely scientific investigations... If the work upon which I have bestowed so much time and thought were a mere triumph over mechanical difficulties, or simply curious, or if the execution of such engines were of doubtful practicability or utility, some justification might be found for the course which has been taken; but I venture to assert that no mathematician who has a reputation to lose will ever publicly express an opinion that such a machine would be useless if made, and that no man distinguished as a civil engineer will venture to declare the construction of such machinery impracticable... And at a period when the progress of physical science is obstructed by that exhausting intellectual and manual labor, indispensable for its advancement, which it is the object of the Analytical Engine to relieve, I think the application of machinery in aid of the most complicated and abtruse calculations can no longer be deemed unworthy of the attention of the country. In fact, there is no reason why mental as well as bodily labor should not be economized by the aid of machinery. -- Charles Babbage, "The Life of a Philosopher" | |

| ...At that time [the 1960s], Bell Laboratories scientists projected that computer speeds as high as 30 million floating-point calculations per second (megaflops) would be needed for the Army's ballistic missile defense system. Many computer experts -- including a National Academy of Sciences panel -- said achieving such speeds, even using multiple processors, was impossible. Today, new generation supercomputers operate at billions of operations per second (gigaflops). -- Aviation Week & Space Technology, May 9, 1988, "Washington Roundup", pg 13 | |
| Even if we put all these nagging thoughts [four embarrassing questions about astrology] aside for a moment, one overriding question remains to be asked. Why would the positions of celestial objects at the moment of birth have an effect on our characters, lives, or destinies? What force or influence, what sort of energy would travel from the planets and stars to all human beings and affect our development or fate? No amount of scientific-sounding jargon or computerized calculations by astrologers can disguise this central problem with astrology -- we can find no evidence of a mechanism by which celestial objects can influence us in so specific and personal a way. . . . Some astrologers argue that there may be a still unknown force that represents the astrological influence. . . .If so, astrological predictions -- like those of any scientific field -- should be easily tested. . . . Astrologers always claim to be just a little too busy to carry out such careful tests of their efficacy, so in the last two decades scientists and statisticians have generously done such testing for them. There have been dozens of well-designed tests all around the world, and astrology has failed every one of them. . . . I propose that we let those beckoning lights in the sky awaken our interest in the real (and fascinating) universe beyond our planet, and not let them keep us tied to an ancient fantasy left over from a time when we huddled by the firelight, afraid of the night. -- Andrew Fraknoi, Executive Officer, Astronomical Society of the Pacific, "Why Astrology Believers Should Feel Embarrassed," San Jose Mercury News, May 8, 1988 | |
| A mathematician, a doctor, and an engineer are walking on the beach and observe a team of lifeguards pumping the stomach of a drowned woman. As they watch, water, sand, snails and such come out of the pump. The doctor watches for a while and says: "Keep pumping, men, you may yet save her!!" The mathematician does some calculations and says: "According to my understanding of the size of that pump, you have already pumped more water from her body than could be contained in a cylinder 4 feet in diameter and 6 feet high." The engineer says: "I think she's sitting in a puddle." | |
| An engineer, a physicist and a mathematician find themselves in an anecdote, indeed an anecdote quite similar to many that you have no doubt already heard. After some observations and rough calculations the engineer realizes the situation and starts laughing. A few minutes later the physicist understands too and chuckles to himself happily as he now has enough experimental evidence to publish a paper. This leaves the mathematician somewhat perplexed, as he had observed right away that he was the subject of an anecdote, and deduced quite rapidly the presence of humour from similar anecdotes, but considers this anecdote to be too trivial a corollary to be significant, let alone funny. | |

| Brief History Of Linux (#10) The AnyQuack Computer One electronic machine, Colossus, was used by the British in World War II to decode Nazi transmissions. The code-breakers were quite successful in their mission, except for the tiny detail that nobody knew how to read German. They had decoded unreadable messages into... unreadable messages. Two years later in 1945, a group of professors and students at the Univ. of Pennsylvania were discussing computing theory. An argument ensued, in which one professor yelled, "Any quack can build an electronic computer! The real challenge is building one that doesn't crash every five minutes." One graduate student, J. Presper Eckert, Jr., responded, "I'm any quack! I'll take you up on that challenge. I'll build a device that can calculate 1,000 digits of pi in one hour... without crashing!" Several professors laughed; "Such high-speed calculations are beyond our level of technology." Eckert and his friends did build such a device. As a joke, he called the machine "AnyQuack", which eventually became ENIAC -- ENIAC's Not Intended As Crashware, the first known example of a self-referential acronym. | |
