1. The laws of physics are the same for all observers in uniform
motion relative to one another (Galileo's principle of relativity),
2. The speed of light in a vacuum is the same for all observers,
regardless of their relative motion or of the motion of the source of the
light.
The resultant theory has many surprising consequences. Some of these
are:
* Time dilation: Moving clocks tick slower than an observer's
"stationary" clock.
* Length contraction: Objects are observed to be shortened in the
direction that they are moving with respect to the observer.
* Relativity of simultaneity: two events that appear simultaneous to an
observer A will not be simultaneous to an observer B if B is moving with
respect to A.
* Mass-energy equivalence: E = mc˛, energy and mass are equivalent and
transmutable.

In the slave days nigg0rs were given watermelons in the fields to prevent
over heating otherwise they would break down from heat stroke. Ya gotta
keep your nigg0r cool.
