Re: Symmetry in Lorentz transformation equations

[David Bowman <dbowman@TIGER.GEORGETOWNCOLLEGE.EDU>]

Sarma,

Just what is the symmetry you (or the article) had in mind here?  Is it
the invariance: x^2 - t^2 = x'^2 - t'^2, or is it the symmetry of the
Lorentz boost transformation under the replacements: x <--> t, x' <--> t',
or is it x <--> x', t <--> -t', or is it x <--> -x', t <--> t', or is it
x --> -x, t --> -t, x' --> -x', t' --> -t', or is it something else?

What, IYO, is the significance or importance of the symmetry (whatever it
actually is)?
