Electronics And Communication Engineering Quotes

An essential innovation during the development stage of the Internet was e-mail. It was invented in 1971 by computer engineer Ray Tomlinson, who developed software to send electronic mail messages to any computer on ARPAnet. He decided to use the @ symbol to signify the location of the computer user, thus establishing the “login name@host computer” convention for e-mail addresses.

At the end of the second orbit, an indicator in the capsule suggested that the all-important heat shield was loose. Without that firewall, there was nothing standing between the astronaut and the 3,000-degree Fahrenheit temperatures—almost as hot as the surface of the Sun—that would build up around the capsule as it passed back through the atmosphere. From Mission Control came an executive decision: at the end of the third orbit, after the retrorockets were to be fired, Glenn was to keep the rocket pack attached to the craft rather than jettisoning it as was standard procedure. The retropack, it was hoped, would keep the potentially loose heat shield in place. At four hours and thirty-three minutes into the flight, the retrorockets fired. John Glenn adjusted the capsule to the correct reentry position and prepared himself for the worst. As the spaceship decelerated and pulled out of its orbit, heading down, down, down, it passed through several minutes of communications blackout. There was nothing the Mission Control engineers could do, other than offer silent prayers, until the capsule came back into contact. Fourteen minutes after retrofire, Glenn’s voice suddenly reappeared, sounding shockingly calm for a man who just minutes before was preparing himself to die in a flying funeral pyre. Victory was nearly in hand! He continued his descent, with the computer predicting a perfect landing. When he finally splashed down, he was off by forty miles, only because of an incorrect estimate in the capsule’s reentry weight. Otherwise, both computers, electronic and human, had performed like a dream. Twenty-one minutes after landing, the USS Noa scooped the astronaut out of the water.

It was possible to look at actual smartphones and tablets and laptops that had been manufactured on Old Earth. They did not work anymore, but their technical capabilities were described on little placards. And they were impressive compared to what Kath Two and other modern people carried around in their pockets. This ran contrary to most people's intuition, since in other areas the achievements of the modern world - the habitat ring, the Eye, and all the rest - were so vastly greater than what the people of Old Earth had ever accomplished. It boiled down to Amistics [the choices that different cultures made as to which technologies they would, and would not, make part of their lives]. In the decades before Zero, the Old Earthers had focused their intelligence on the small and the soft, not the big and the hard, and built a civilization that was puny and crumbling where physical infrastructure was concerned, but astonishingly sophisticated when it came to networked communications and software. The density with which they'd been able to pack transistors onto chips still had not been matched by any fabrication plant now in existence. Their devices could hold more data than anything you could buy today. Their ability to communicate through all sorts of wireless schemes was only now being matched - and that only in densely populated, affluent places like the Great Chain... Anyone who bothered to learn the history of the developed world in the years just before Zero understood perfectly well that Tavistock Prowse had been squarely in the middle of the normal range, as far as his social media habits and attention span had been concerned. But nevertheless, Blues called it Tav's Mistake. They didn't want to make it again. Any efforts made by modern consumer-goods manufacturers to produce the kinds of devices and apps that had disordered the brain of Tav were met with the same instinctive pushback as Victorian clergy might have directed against the inventor of a masturbation machine. To the extent the Blue's engineers could build electronics of comparable sophistication to those that Tav had used, they tended to put them into devices such as robots...

Synthetics diminished the great powers' need for strategic raw materials by offering substitutes. Aviation, cryptography, radio, and satellites, meanwhile, enabled those powers to run secure transportation and communication networks without worrying about contiguous territorial access. Innovations in medicine and engineering - such as DDT, antimalarials, plastic-based packaging, and "world-proofed" electronic equipment - further reduced the need for territorial control. They allowed objects and humans to safely travel to hostile terrains, meaning that colonizers didn't have to soften the ground beforehand. Standardization, similarly, made foreign places more accessible. (Page 314, 315)

He came to an inner dividing cover at the centre of the catalogue. For the first time, the centre cover announced, Electronic Service-Unit 16 offers a complete line of interocitor components. In the following pages you will find complete descriptions of components which reflect the most modern engineering advances known to interocitor engineers. “Ever hear of an interocitor?” “Sounds like something a surgeon would use to remove gallstones.” “Maybe we should order a kit of parts and build one up,” said Cal whimsically. “That would be like a power engineer trying to build a high-power communications receiver from the Amateur’s Handbook catalogue section.” “Maybe it could be done.

Our understanding of the world and our well-being rest, to an insufficiently appreciated degree, on the scientific and engineering advances made between 1867 and 1914. Those decades saw the invention and commercialization of internal combustion engines, electricity generation and electric lights and motors, the inexpensive production of steel, the smelting of aluminum, the introduction of telephones, the first plastics, the first electronic devices, and a rapid expansion of wireless communication. We also came to understand the spread of infectious diseases and the nutritional requirements for healthy growth (above all, the need for adequate protein intake), as well as the need for indispensable plant nutrients in securing abundant and affordable food supply.

It is never certain for her that the wolves will answer each Wednesday. I wonder for a moment why they do. Surely they know that these are just a bunch of humans trying to speak wolf. Surely they smell us, a group of sixty people cloaked in lotions, colognes, insecticides, and deodorant - announcing our odiferous presence to an animal whose world is ordered by scent - standing in the woods a mere few hundred yards away. Surely they heard our engines as we arrived. Surely they could hear that our pitch is off, that we are an imitation. Yet they accept this and play along. Why? Wolves, it turns out, will howl to a variety of stimuli, including the sirens of emergency responder vehicles. In the late 1960s, when researchers discovered that the red wolf was nose-diving into extinction, they played electronic sirens in southeastern Texas coastal marshes and plains to elicit howls from wild canids. From the howls, they made probable identifications of red wolves and possible hybrids. Coyote vocalizations often have a series of broken yips and barns and emanate at a comparatively higher frequency, whereas red wolves will howl at lower frequencies that start “deep and mournful” but may break off into yapping like a coyote, according to a report authored in 1972 by two trappers, Glynn Riley and Roy McBride, who were employed by the federal government. Early surveyors noted, too, that the red wolves were more likely to howl in good weather and less likely to respond in rainy or overcast weather. Confined to their facility, perhaps the red wolves of Sandy Ridge howl to humans because it gives them a way to communicate with living beings outside their fence. Who knows: maybe they are simply telling us to bugger off and go away. Or, as frightened as they are of seeing a human, perhaps howling to a group of them on a dark night is more palatable since they do not have to look at us or be gawked at in turn. Perhaps howling is a way of reaching out on their own terms, in their own language, through which they can proclaim their space and their place on the land - their way of saying, “Even though I’m in here, behind this fence, I own this place.” Or maybe they just want to remind us that this land had been theirs for millennia before we invaded and claimed it. In the dark of night, I fantasize that their howls are calling out: “All this was ours. This was ours.
