Galilean coordinate transformations have to be modified Review what are Galilean coordinate transformations ? (these work well at low relative velocities e. g. everyday life but not for GPS or particle accelerators) (x, y, z, t) are Earth coordinates; (x’, y’, z’, t’) are spacecraft coordinates. The spacecraft is moving at constant velocity u with respect to Earth. “obvious” 25

Galilean velocity transformations have to be modified (x, y, z, t) are Earth coordinates; (x’, y’, z’, t’) are spacecraft coordinates. The spacecraft is moving at velocity u with respect to Earth. Now differentiate with respect to time t “obvious” First worked this out in Chapter 3 of Young and Freedman ! But this does not work for u=c ! Violates Einstein’s second postulate 26

Galilean velocity transformations have to be modified But this does not work for u=c ! Violates Einstein’s second postulate. (speed of light is the same in all frames). Question: How can we fix this ? Something was wrong in the derivation. But what ? Ans: The assumption t=t’ is flawed. Need to introduce 4 dimensional spacetime (x, y, z, t) and (x’, y’, z’, t’) 27

Special Relativity Example (cont’d) • Example: As a high speed spaceship flies past you, it fires a strobe light that sends out a pulse of light in all directions. An observer aboard the spaceship measures a spherical wave front that speeds away from the spaceship at speed c in all directions. Is the spherical wavefront centered on the spaceship ? Ans: No. It is not centered on the current center of the spaceship but rather on the location of the spaceship where the light was emitted. Further explanation: If the spaceship is moving at c/3 and time t has elapsed since the pulse was emitted, the wavefront is a sphere of radius ct centered on P and the spaceship is now a distance of ct/3 away from P 30
