Bob is moving to the right (positive x direction) in his spaceship at a velocity v, and Alice is observing him. If we want to draw Bob’s world line on Alice’s spacetime diagram, how do we figure out where it goes?

Because Bob is moving to the right, the Lorentz equations show that his world line will be at a 45 degree angle to Alice’s time axis.

Bob’s world line in his frame of reference is the line where x_B equals 0, so substitute that into the appropriate Lorentz transformation to find a relationship involving x_A and t_A, which can be plotted on Alice’s diagram.

Bob’s world line is the line where t_B equals 0, so substitute that into the appropriate Lorentz transformation to find a relationship involving x_A and t_A, which can be plotted on Alice’s diagram.

Bob’s world line will be identical in both his spacetime diagram and Alice’s spacetime diagram, so there’s no need to figure anything out.

Let Bob have a spaceship with a clock at each end, both of which are synchronized in his frame of reference. Alice has an identical spaceship with a clock at each end, both of which are synchronized in her frame of reference. Her spaceship is docked at the local spaceport, with the front end pointed to the right (positive x direction). Meanwhile, Bob flies by in his ship at a speed V heading to the right (positive x direction). Alice observes Bob’s clocks as he flies by. What does she observe, according to her frame of reference (and lattice of synchronized clocks)? (Tip: Sometimes it helps to draw a picture to visualize what’s going on.)
