Why is c equal to (roughly) 3^10E8 m/s? Why not 3^10E108 m/s? Or 3^10E1 m/s? Is c some arbitrary value that just "falls out of the math", or is there actually a physical characteristic that sets it?
'S been a looong time since I got out of school, and the electron-pushing business is much more interested in what happens than why. A similar (related?) question applies to Zo, the characteristic impedance of free space.
