    One of my favorites - There are 10 types of people in this world. Those that understand binary math and those that don't.

    I believe the MR2 of team "Nerd Herd" at LeMons had that. It was totally lost on most of the other competitors.

    Quite nice, and lost on 99.999% of the population.

    More energetic blue. Shorter wavelength due to doppler effect on the light waves.

    @AtlBchGator: Ohp, correct, I had first written it as a red shift explaination, but figured blue would make more sense. Corrected.

    A more Jalop sticker would be blue and state "If this sticker is red, you are losing badly."

    @YankBoffin: But how could they see it if the stickee (that is the person who has the sticker) is going faster than the stick-er (the person who views the sticker).

    Your logic is flawed!

    @spiegel1: You're beginning to understand.

    Now, how are you ever going to get to your car tonight after work if, on the way to your car, you first have to go half way there? And to get to that halfway point, you first have to go half way there? But, to get to that point, you first have to get half way there? Ad infinitum...

    @spiegel1: Um, if you're driving on the highway, and there's a car in front of you who is going faster than you, can't you still see their bumper sticker?
    Assuming that you could read something on a vehicle whose relative velocity is a reasonable % of the speed of light, it doesn't matter if it is you or they who are going faster. If you are going faster, the compression of space-time results in the blue shift (wavelength shrinks) while if the other driver is going faster, the expansion of space-time results in the red shift.
    In neither case is the relative speed greater than light speed (as of course, this is impossible - you cannot exceed light speed either in relative or 'absolute' speeds, which is interesting - two objects travelling 0.9c relative to a given reference frame, but in opposite directions are still travelling less than c relative to each other), so it is always possible for light to propagate from the 'stickee' to the 'sticker'.

    @beercheck: I just simply integrate the distance between me and my car.

    And if my math is correct, by the time I'm finished with the equation, I should be in my car.
