He steadied the small red vehicle and pointed it for Earth. He added: "I'm firing a six-two solid-fuel job, Chief. Counting three. Three two one." His mount vanished in rocket fumes. But after six seconds at two gravities acceleration the rocket burned out. The Chief had fired a matching rocket. They were miles apart, but speeding Earthward on very nearly identical courses.
Haney pushed both hands down, raised one, pushed again. The Chief had one finger down. Mike had both firing buttons depressed.... The Chief pushed down his second button, quietly. There was a monstrous impact. Every jato in every pushpot about every launching cage fired at once. Joe felt himself flung back into his acceleration chair. Six gravities.
The authors of Gayeties and Gravities give it as their opinion that no object of sight is regarded by us as a simple disconnected form, but that an instantaneous reflection as to its history, purpose, or associations converts it into a concrete one, a process, they shrewdly remark, which no thinking being can prevent, and which can only be avoided by the unmeaning and stolid stare of "a goose on the common or a cow on the green."
Most people stayed awake through the six-gravity stage and went heavily to sleep under three gravities. Cochrane fought the sensation of fatigue. He had not liked himself for accepting the orders that had brought him here.
Further, it appears that such qualification of the process as results from the more rapid genesis of heat in the larger masses, will be countervailed where high velocity of rotation greatly impedes the circulating currents. Thus interpreted then, the various specific gravities of the planets may be held to furnish further evidences supporting the Nebular Hypothesis.
It seemed like an eternity five and a half gravities of acceleration held the men in their chairs almost as well as the straps of the antiacceleration units that bound them. When a man weighs better than half a ton, he doesn't feel like moving much. Fuller whispered to Morey out of the corner of his sagging mouth. "What on Earth I mean, what in Space is that thing?
You, whom I dare proudly count among the latter, may be more and more convinced that you will ever find in me what Orestes was to his Pylades, and that it is not possible for any one to esteem and love you more than your devoted Frederick." "Now," said the prince, as he arose, "away with the burdens, the gravities and cares of life! Come, now, spirit of love! spirit of bliss!
They consumed themselves as they went, and they attained an acceleration of fifty gravities once they were relieved of all load but their own substance. They had to be released lest one burn longer than another. It was also the only way to stop acceleration by solid-fuel rockets. They couldn't be extinguished. They had to be released.
It was no longer upheld by pushpots. It was free, with its take-off rockets flaming. It plunged on up and out. But the acceleration was less. Nobody can stand six gravities for long. Anybody can take three for a while. Joe's body resisted movement with a weight of four hundred and fifty pounds, instead of a third as much for normal.
The Twaddell hydrometer, or instrument for measuring the specific gravities of liquids, is so constructed that when it stands in water, the water is just level with its zero or 0° mark. Well, since in your reading of methods and new processes, you will often meet with specific gravity numbers and desire to convert these into Twaddell degrees, I will give you a simple means of doing this.
