Tam only saved himself by taking the risk of a spinning nose dive into that zone of comparative safety which is represented by the distance between the trajectories of high-angle guns and the flatter curve made by the flight of the eighteen-pounder shell.
The engine rooms were easily identified. In one area he heard the banging of pots and pans, the steaming of kettles ... obviously the galley. He found the control area. He could hear the clatter of typing instruments, the click-click-click of the computers working out the orbits and trajectories for the scout-ships as they moved out from the orbit-ship or came back in.
He gave a perfect Brock's benefit of diagrams exactly like rocket trajectories they were; and the gist of it so far as it had any gist was that the blood of puppies and kittens and the sap of sunflowers and the juice of mushrooms in what he called the "growing phase" differed in the proportion of certain elements from their blood and sap on the days when they were not particularly growing.
And I, sole scorched survivor from the blaze, sit writing of it here in an air that is never still for the clang and thunder of machines, on a table littered with working drawings, and amid fragments of models and notes about velocities and air and water pressures and trajectories of an altogether different sort from that of Tono-Bungay.
He was still in the toils of the might-have-been, of that wasting process an examination, and turning over in his mind logistics, logarithms, trajectories, equations, and a mob of disconnected questions. "Oh, by George!" he exclaimed, "what's the worth while of it?"
Great as have been our achievements in physical astronomy, we are as yet wholly unable to understand why a power pervades the system acting inversely as the squares of the distance from the point to which it attracts, rather than a power acting according to any other law; and why it has been the pleasure of the almighty Architect of that universe, that the orbits of the planets should be nearly circular instead of approaching to, or being exactly the same with many other trajectories of a nearly similar form, though of other properties; nay, instead of being curves of a wholly different class and shape.
One part of his mind assured him that the statement that mechanical computers could not calculate trajectories of missiles with changing acceleration was incorrect. But the rest of his mind tried to imagine such a trajectory. He couldn't. In practice, men do not have to handle the results of variable acceleration as cumulative effects. "I think," said Bors carefully, "that if you can do that "
The C.I.V. officers talked of Lee-Enfields, trajectories, mass and volley firing; the Indian Staff Corps men, who were going out on special service, spoke of commissariat and transport, of standing patrols and Cossack posts, of bivouacks, entrenchments, vedettes, contact squadrons, tactical sub-units, demolitions and entanglements.
Keeping the car high enough to be above the trajectories of incoming shells, Harry Quong circled over the city while Hassan Bogdanoff talked to Gongonk Inland on the radio. The city was in a bad way. There were seventy-five to a hundred big fires going, and a new one started in a rising ball of thermoconcentrate flame while they watched.
The question of high velocities and flat trajectories without lightening the weight of the projectile was the desideratum; the minimum of weight in the cannon itself with the maximum in the projectile and the force with which it could be propelled were the ends to be attained.
