The mathematician who makes the calculations for a machine is not so well paid as the man who finishes it; the observatory calculator who calculates the time of occulation for a planet cannot earn so much as the one who grinds a reflector. In all our life the same tendency is to be seen: the work of the hand outdoes in value the work of the brain.
It consists of 372 dual-monopole vertical elements each 19 feet high, backed by a huge reflector screen which makes the antenna substantially unidirectional. Each pair of vertical elements has its own receiver which digitizes the incoming signals. All the digitized signals are then fed through a fibre-optic link to a master signal processor.
Here was the tachometer, that would give to a fraction the revolutions of each screw per minute; here the altimeter, to indicate height; here the air-speed indicator, the compass with reflector, the inclinometer, the motometers to show the heat in each engine and there, the switch to throw on the gigantic searchlight, with the little electric wheel to control its direction, as accurately as you would point a wand.
Agreeably to the dimensions already specified, the area of the 10-inch heater acted upon by the reflected solar rays is 331.65 square inches, the area of the 20-inch heater being 673.9 square inches. The section of the annular sunbeam whose direct rays act upon the polygonal reflector is 3,130 square inches, as before stated.
"Before I come here I never had nothing in my kitchen but an oil lamp and a reflector. Jest as sure as I'd be dishing up dinner, hot nights, that lamp would begin to flicker and suck well, shucks! I'd look up at it and I'd say, 'Well, why don't you go out? Go ahead!" Mrs. Tolley laughed joyously.
"Come to order," says the chairman, and we have here at this moment in operation the greatest institution in this round world: the institution of free self-government. Great in its simplicity, great in its unselfishness! And Baxter's old lamp with its smoky tin reflector, is not that the veritable torch of our liberties?
The group of Independents are now on the ferryboat. Across the river the myriad lights of the metropolis give the scene air appearance as of fairyland. The night is overcast and the clouds act as a reflector to the million lights in the city below; the sky line of Brooklyn is a dull salmon color. A chill October wind sweeps from east to west. It is a bad night to speak out of doors.
There are reflectors above the bank windows which face the court, and it appeared to Bristol that there was a hole in one of these, the furthermost from the corner. A tiny beam of light shone from the bank window on to the reflector, or from the reflector on to the window, which circumstance in itself was not curious.
Then at each end of the lean-to be and Charley placed a thick barricade of spruce brush. A floor of boughs finished and made comfortable the shelter, and a fire built against a rock in front of it, that the rock might serve as a reflector, soon made the lean-to warm and snug.
My reflector discovered this comet, thanks, of course, to the good use you made of it, and it seems to me that I'm in a way responsible for making it harmless if that can be done, and so I'm not disposed to take that convenient colliery as a gift from anyone, no, not even you, Lord Westerham.
