The natural frequency of this light makes it red. At 0 velocity, the equation would be length * sqrt(1-v^2/c^2) or length * sqrt(1-0^2/c^2) or just length. So, no, it should still be red. I’m pretty sure this isn’t natural light being refracted, so I don’t know of any crazy length manipulations that could turn this into white.

ParticipantArladerus said: What if you’re traveling away from the text?Objects around you shrink in length as you approach the speed of light. The wavelength of the light would shrink, making it change from red to blue.
Edit: Technically, things shrink more and more in length from an observer’s perspective as they approach the speed of light. However, even thought you’re moving, from your perspective, you’re at rest and everything else is moving.
Second Edit: So it doesn’t have anything to do with whether you’re going towards or away from it.

Then what do you redcoats call it?
Carbonated beverage.
Around here everything’s called Cola, thank you very much.
Why, I never! What’s there to differentiate Coca Cola, Shasta Cola, Pepsi Cola, or RC Cola from a generic brand of cola? Are you telling me you would call 7UP or Sprite a cola?! Sunkist or Fanta?! MOUNTAIN DEW OR MELLOW YELLOW?!?!?!?!??!?!
Yep, it’s all cola. Cola = your pop or soda.

ParticipantPirkid said: It’s like the double slit experiment.Shooting particles through one slit makes one band of particles at the back wall.
Shooting particles through two slits makes two bands of particles at the back wall.Shooting a wave through one slit creates an intensity gradient on the back wall with the most intensity in the middle and weakening as you move to the sides.
Shooting a wave through two slits creates an interference pattern. Where the two waves (from the two slits meet) collide, they cancel each other out. So on the bback wall, you getting alternating intensity and nothing. Intensity appears when the two waves meet the wall. Nothing is when the waves collide and cancel each other out.
BTW, when I say particles, I mean everyday objects like marbles or cats or muffins or whatnot.
Now, when you shoot electrons* through a single slit, you get a single band on the wall. Normal.
But when you shoot electrons through two slits..you get an interference pattern.
How can pieces of matter create a wave-like intereference pattern?So we observe the double slit filter. Let’s see which slit the electron choose to go through, right?
Wrong. With the addition of a mere observer, the electron changed the way it worked. When a measuring device was added to watch the double slit filter, the electrons created a normal, two band pattern in the back wall, not an intereference pattern like before.
The observer collapsed the wave function..simply by observing!
We did this experiment in grade 12 with red light and all kinds of fun stuff.
We did this experiment too (in 11th and 12th grade). First time I saw it, they were picking up chunks of my mind off the floor afterwards.

You do not see the cat, you see only a box.
Thus, the cat in there could be alive… or dead.
But you don’t know until you open the box do you?
Thus, the joke.
No, not quite.
It really started with the issue in physics that things can act like particles or waves (very different) at the same time. In a sense, they are both at once. These are two very different states. It’s like dribbling a ball and spinning that same ball on your finger at the same time. How is this possible?
That’s where the idea of superposition comes in. Of course, it deals with a lot more than just waves/particles, but that’s the easiest one to understand. Superposition says that both states/options exist at once. When you observe it, though, it loses that duality.
“One can even set up quite ridiculous cases. A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small that perhaps in the course of the hour, one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges, and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts.
It is typical of these cases that an indeterminacy originally restricted to the atomic domain becomes transformed into macroscopic indeterminacy, which can then be resolved by direct observation. That prevents us from so naively accepting as valid a “blurred model” for representing reality. In itself, it would not embody anything unclear or contradictory. There is a difference between a shaky or out-of-focus photograph and a snapshot of clouds and fog banks.” – Schrodinger himself
Basically, there is either radioactive decay that ultimately kills the cat or nothing happens. Because of superposition on the subatomic level, this means that both states exist at once. If you follow the chain, this means that the cat is both dead and alive inside the box.
And that’s why we leave this stuff to the people who have way too much free time on their hands o;
Or get paid lots of money to work at CERN and think about this sort of stuff.

Not a paradox. Not if you understand the concept of quantum superposition.

Tables turned, done.Did you just say purify drugs? You realize that’s impossible, right? You can’t make heroine safe. The only way to make heroine safe is to make it not heroine.
Legalizing drugs works for a lot of things, but not seriously dangerous drugs (e.g. heroine).

Because none of us are hanging out with our ex’s on a saturday night =( Not that we want to. Well some of us dont want to.Ironically, I hung out with my ex that Saturday.
OT: None of these movies interest me, otherwise I’d try to participate.

ParticipantThe sidescrolling format of MS is really cool. The closest any game has come to it is probably Wonder King. I can’t stand the grinding of either game. The community is really what kept me going in MS. I can’t comment on Wonder King’s. I gave up on it in Closed Beta. Grinding ftl. My favorite MMORPG remains Talesweaver.
Oh, and Free Realms F2P is a joke. Very little is actually free.
