From the stationary corridor, it was easy to see that this section of the Atlas rotated. Like other ships of this age, acceleration gave the circular walls a semblance of gravity.
	Unlike the other portions of the dated carrier, however, this section wasn’t cylindrical, but rather a segmented cone. The outer portion was wider and rotated more slowly than the narrower inner portion—simulating gravitational forces from one quarter to two gravities along the length of the gym.
	John started with arm curls. He went to the center section, calibrated at one gee, and picked up a twenty-kilogram dumbbell. It felt wrong—too light. The spin must be off. He set the weights down and picked up a forty-kilogram set. That felt right.
