The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science.
In terms ofcommunication,Japan isliketheblack hole of the universe. It receives signals but does not emit them.
When he let Kennedy use his column to send signals to Nikita Khrushchev, or lent his skill to Vandenberg to reinforce the anti-Soviet consensus in American diplomacy, he wasn't acting as a reporter but as a patriot. This urge may be a dereliction of duty in the journalist, but it is a sign of decency in the man. That the two impulses in journalism should so often be at odds — duty versus decency — tells us more about the trade than most of us care to know.andrew ferguson
Fire signals of an attack were also raised toward Thebes, but the Plataeans in the city at once displayed a number of others, prepared beforehand for this very purpose, in order to render the enemy's signals unintelligible, and to prevent his friends from getting a true idea of what was happening and coming to his aid before their comrades who had gone out should have made good their escape and be in safety.Thucydides
Every human being lived behind an impenetrable wall of choking mist within which no other but he existed. Occasionally there were the dim signals from deep within the cavern in which another man was located so that each might grope toward the other. Yet because they did not know one another, and could not understand one another, and dared not trust one another, and felt from infancy the terrors and insecurity of that ultimate isolation there was the hunted fear of man for man, the savage rapacity of man toward man.Isaac Asimov
“The advantage of molecular messaging over other sorts of communication, he says, is its ability to be deployed in hard-to-reach places, such as providing in-body communications for medical applications. The body’s cellular signalling pathways have already been mapped, so these could serve as “communications channels”, says Dr Bush. Digital signals could be sent, say, to the vagal system to help moderate a patient’s blood pressure or heart rate. Data transmitted molecularly might also enable blood-sugar levels to be monitored without invasive pinpricks.”stephen bush
And if our future Lies on the final line Are we brave enough To see the signals and the signs?harry chapin
They have had numerous extraterrestrial signals. They were apparently searching in a spectrum or in an area . . . where they hit the mother lode. The signals were so numerous that they began to have their systems externally jammed by some sort of human agency that did not want them to continue receiving those signals... [I received this information from a source in SETI.] This person, if I were to say who he is, almost every one your listeners would probably know the name. (July 30, 2006)steven m. greer
Breaking into a country signals quite reliably a willingness to break yet more of the invaded country’s laws.ilana mercer
For neo-conservatism is a quintessentially Jewish project: a re-sanctification in everyday life of the core values of western civilisation, and the achievement of human potential through virtuous practice. The neo-cons’ crucial insight is that public signals through law, custom and tradition are the key to getting people to behave well. And that is a Jewish insight.melanie phillips
I had looked forward to old age as a time of quietness, a time to draw my horizons about me, to watch memories ripening in the sunlight of a walled garden. But there is the void over my head and the distance within that the tireless signals come from. And astronaut on impossible journeys to the far side of the self I return with messages I cannot decipher.r. s. thomas
Traffic signals in New York are just rough guidelines.david letterman
For ages the world has been waiting and watching; millions, with broken hearts, have hovered around the yawning abyss; but no echo has come back from the engulfing gloom silence, oblivion, covers all. If indeed they survive; if they went away whole and victorious, they give us no signals. We wait for years, but no messages come from the far-away shore to which they have gone.
If they have a strong feeling or indication that the debris belongs to the aircraft, one of the first things authorities will do is drop sonar buoys in the water. If the black box (flight recorder) is there, the buoys should be able to pick up the signals. This could take up to 48 hours but it all depends on how near or far the ships and other assets are.
We do not copy Google's search results. We use multiple signals and approaches in ranking search results. Opt-in programs like the toolbar help us with clickstream data, one of many input signals we and other search engines use to help rank sites.
