My new favorite bumper sticker

Nerdy physics/astronomy humor FTW. If you don’t get it (and it’s OK if you don’t, really), you might refer to Wikipedia’s article on blue shift. You can buy variations of this bumper sticker all over the web, but I’ve no word, alas, on how to score one of these official APS versions. [via Neatorama]

  1. There is an upcoming event at Portland, OR Convention center in March where you can stop by their gift shop and probably pick one up.

  2. There is a big assumption here – that the viewer of the sticker is following and fast approaching the card the bumper of which displays the sticker. If the leading car with the sticker is going as fast as the following – no Doppler shift; sorry. And if the leading car is moving faster than following or if the cars are moving in opposite directions – the shift would be into infra-red and further.

  3. @sasha: The way I see it, the statement on the sticker still stands (and, if anything, is strengthened by your statement). Obviously, if your going the same speed or slower than the car with the bumper sticker (a situation where you said the color would either stay red or towards infra-red) then you aren’t “driving too fast” from the relative viewpoint of the bumper sticker-ed car’s driver. And, as physics tells us, everything is relative…

    1. So relative to what you’d be driving fast then? All I was saying that any statement (this including) is made valid (or not) by a truck-load of assumed or explicit contextual conditions. But 10 out of 10 for the sense of humor to those guys, anyway.

    1. as I rib my friend about can take the fun out of any joke. If you have to overanalyze, you may not have a sense of humor.
