A couple of lines from my Physics teacher that I hope I remember right after all these years.
There was a young fellow called Fisk
Whose swordplay was exceedingly brisk
So fast was his action
That Fitzgerald Contraction
Reduced his foil to a disc
and
There was a young fellow called Bright
Who could travel faster than light
He went out one day
In a relative way
And came back the previous night
Mike Berry, despite contrary indications you must have taught me something!!
