Johns trajectory (the dashed line) and Heathers trajectory (the solid line) in spacetime.
John is stationary while Heather moves at a constant speed in a circle.
Ann, and two ships accelerating from rest at the same rate.
The trajectories of the two spaceships, idealized as points, as viewed in Anns reference frame. Notice that the two ships always have the same horizontal separation in this frame.
The gray lines are instantaneous lines of simultaneity for the tailing spaceship. Each line intersects the leading ships trajectory farther from the corresponding point where the line of simultaneity originated on the tailing ships trajectory.
Loies spinning disk. Notice how at any given moment, points on a line drawn from the center of the disk to its edge have velocities that are perpendicular to that line.
Divide Loies disk into N segments and imagine speeding it up a bit. The acceleration of the leading end point of any segment must be larger than the acceleration of the segments tailing end point.
Higher water pressure at the bottom of the tin produces a bigger force there than at the top of the tin.
A submarine at rest. Its density is the same as that of water, so the buoyant force, Fb, exactly counteracts the force due to gravity, Fg.
The submarine starts to move to the right. The buoyant force is now smaller.
From the point of view of the submarine, the water is flowing to the left. In this frame, the buoyant force is apparently greater.
Using calculus, you can think of the total buoyant force as being the sum of contributions from a bunch of little packets of displaced waterthe little cubes on the right.

Acknowledgments
This book was a departure from my romance with thriller writing. Fiction is pure invention. The novelist creates the characters and joins in their adventures. Writing this book was an exercise in discovery. The process was a tale of many labyrinths, all part of a greater maze.
